The consistency of a watery sauce prevents the sauce from sticking to the pasta and causes the pasta to absorb water, leading to soggy pasta and a ruined meal. Thickening tomato-based sauces requires adding tomato paste, pureed vegetables or meat, depending on your desired flavors. Save a watery sauce by fixing it with simple and savory ingredients in time for service.
Boil the tomato sauce uncovered for five to 10 minutes to evaporate some of the excess water. Stir the sauce so that it does not stick to the bottom of the pan and burn.
Add one can of tomato paste to thicken the sauce. Stir the paste into the sauce and reduce the heat to a medium temperature.
Add a cream-based product such as butter, heavy cream or grated Parmigiano-Reggiano cheese to thicken the spaghetti sauce.
Puree one roasted pepper and one onion in a food processor if you desire those flavors in your sauce. Add the pureed vegetables to the sauce as a thickening agent to absorb the water. Stir the pureed vegetables and sauce.
Pour 1 cup of olive oil into a skillet. Cook hot or sweet Italian sausage, based on your preference, and ground beef for about 10 minutes until golden brown. Add the sausage and beef to the tomato paste to absorb the moisture and thicken it. This turns your spaghetti sauce into a Bolognese sauce and creates juicy, flavorful meat.

Burn marks on a cookie sheet from foods,tomato paste,ash or corrosion can warp or pit the bakeware. Warped cookie sheets unevenly distribute heat resulting in more damage to the cookie sheet over time and undercooked or overcooked foods. Burn marks can also damage non-stick coatings, making a non-stick cookie sheet unusable. To remove burn marks from a cookie sheet, as with any bakeware, start with a mild cleaning solution and move on to harsher cleaning solutions, if necessary.
Soak the cookie sheet in warm water and a mild dish detergent to dissolve and break up burned-on foods and liquids, as well as any metal corrosion caused by intense heat.
Wash the sheet with a microfiber cloth or sponge. If cleaning a hard-metal and uncoated cookie sheet, scrub at the marks with a scratch-resistant scrubbing pad or with fine steel wool. If cleaning a non-stick or aluminum cookie sheet, test a small area of the rim or exterior bottom of the sheet using the scratch-resistant scrubbing pad. Only use the pad to rub away burn marks if the pad doesn’t scratch the surface during the spot test.
Place tomato paste or ketchup on the burn marks found on an uncoated cookie sheet. Wait 30 minutes, rinse, wash and then dry with a clean microfiber cloth. The acid in the tomato paste or ketchup breaks down any burned-on foods, liquids, ash (if the pan was used on a grill) and corrosion marks. If you have tough burn marks on a non-stick or aluminum cookie sheet, skip this section and call the bakeware manufacturer or stain removal instructions.
Make a paste of equal parts baking soda and water if the acid in the tomato paste did not remove the burn marks. Rub the baking soda paste onto the cookie sheet using a scratch-resistant scrubbing pad or fine steel wool. Wash, rinse thoroughly, and dry with a clean cloth.
Use an oven or metal cookware cleaner like GrillPro? Natural Grill & Oven Cleaner or EASY-OFF? Fume Free Oven Cleaner if you’re unable to remove the burn marks using the tomato paste or baking soda methods.

Tomato paste, which are rich in a powerful antioxidant known as lycopene, have been proven useful in promoting heart health. In many cases, they can help to lower high blood pressure as well as assist in preventing heart disease. While these delicious fruits are wonderful all on their own, the truth is that few of us would eat large enough quanities of them every day to have the kind of impact we might want. However, by using them in the more condensed and intensified version of tomatoe suace, we broaden the number of ways that tomatoes can be used in our daily meals.
Use all-natural tomato sauce for the best nutritional and health impact. Make your own tomato sauce or shop for organic and/or other versions that are not packed with extra chemicals and preservatives. Extra chemical ingredients can actually do more damage that not using tomato sauce at all.
Mix the tomato sauce with other heart healthy ingredients whenever possible. For example, if you must use oil in your chosen recipe, choose olive oil rather than canola or vegetable oil. Olive oil, added to tomatoes actually helps to enhance the fruits flavor and increases its curative values. Add a little garlic for yet another heart healthy ingredient to expand the product’s health impact.
Pick the leanest type of meat products in recipes that contain both tomato and a ground meat of some kind. Try ground round rather than ground meat, which tends to be fattier in nature. Better yet, choose buffalo, which provides the leanest type of meat of all while also offering an extra dose of healthy protein.
Use tomato sauce to make your own tomato or V8 style juice. You will experience more than five times the amount of natural tomato goodness and nutrient benefits without all of the additives and preservatives found in most canned juices.
Make homemade tomato soup with tomato sauce and other ingredients like sour cream vegetable stock, heavy cream, or any other ingredients that you typically use in your tomato soup.
Substitute tomato sauces for other types of sauces or gravies in recipes. For example, instead of a beef gravy served over a meatloaf, use a tomato sauce topping.
Use tomato sauce for whole tomatoes in recipes that call for them. Chances are the food will taste better and you will get the additional benefit of a tomato’s heart healthy benefit without the bulk of a whole tomato.
Rather than making a meat sauce for spaghetti, simply add some hearty healthy tomato sauce along with garlic, oregano, Italian seasoning, or any other spices that you like to use. Increase the heart healthy benefit of the meal by choosing to use whole wheat or multi-grained pasta instead of the traditional white pasta. If you want you can even add a few fresh tomatoes on top for a stronger tomato taste or as a garnish.
Use tomato paste sauce as a substitute for tomato juice in drinks like a Bloody Mary, rather than pre-canned tomato juice. Mix up your own natural juice for the occasion. It can be a supplement for your diet to ensure that you have a sufficient amount of lycopene in your diet.

Many home cooks now opt to make their own marinara sauce, because it offers a fresh tomato paste flavor and is easy to make. Yet sometimes homemade marinara sauces can become too runny or thin. To thicken your marinara sauce, try the following steps to bring your sauce to the consistency of your liking.
Simmer your sauce. The longer you simmer your sauce, the more your sauce will thicken. Set your burner on low heat and allow your sauce to simmer until it reaches a thick consistency. Stir the sauce every few minutes to keep it from burning. You may have to wait a couple hours before the sauce reaches a thickness you like. If you decide to use this method, understand that the flavors of the sauce will become more robust as it thickens. Refrain from seasoning and salting your sauce until it is almost ready to serve.
Make a slurry. If you do not have time to simmer your sauce, make a quick slurry out of white rice flour and cold water. Mix 1 tablespoon white rice flour with 2 tablespoons water, then whisk the slurry into your sauce. Let the sauce simmer for at least 15 minutes to allow the slurry to take effect. You can find white rice flour in the Asian section of your supermarket or in an Asian grocery store. You may substitute cornstarch for the rice flour, but the rice flour will not add any noticeable flavor to your sauce.
Try tomato paste. Add tomato paste to your sauce 1 teaspoon at a time until it reaches a thick consistency. Only use tomato paste as a last resort, because it can alter the flavor of marinara sauce.

Few of us expect to feel our lips tingle and our chests constrict when we bite into a pizza or an Italian sandwich . But for the small number of people with an allergy to tomato, that’s exactly what can happen. Though most of us know that food allergies are prevalent and even on the rise tomato paste, the symptoms of tomato allergies are lesser known than that of more publicized food allergies. That doesn’t mean that the symptoms are any less severe or worth less notice than those of other food allergies.
Recognize the difference between a food intolerance and a true allergy. Food intolerances are more common than food allergies and, though the body’s chemical reaction to the food can cause very real and unpleasant symptoms, food intolerances have less potential for fatality. A true allergy to tomato is rare and caused by a histamine reaction to a protein usually found in the seeds, skin and juice of the tomato.
Take note of when the symptoms occur. Food allergy symptoms tend to manifest very soon after the food is ingested. It’s important for your doctor to know the timetable so that he might rule out whether you are experiencing a life-threatening allergic reaction or a food intolerance. You should also take note as to whether your symptoms have become increasingly worse with each exposure to tomatoes.
Avoid fresh tomatoes if after eating them you experience swelling or itching around your mouth, hives, diarrhea, vomiting, difficulty breathing or a persistent skin rash. Though scientists don’t know the exact reason, many people with an allergy to tomatoes only experience symptoms when in contact with the raw fruit. Some patients can eat processed products such as catchup or tomato paste with no discernible reaction.
Connect tomato allergy symptoms to other food contact allergies. The tomato plant is closely related to potatoes, eggplant and tobacco. They are all members of the Deadly Nightshade family and have a similar structure. Since a true tomato allergy is so rare, if you’re allergic it’s likely that you will have symptoms after contact with these other foods too.
Make an appointment with an allergist or your family physician for food allergy testing tomato paste. For a suspected tomato allergy, you are likely to undergo both blood tests and pin-prick allergen testing. Pin-prick testing allows the allergist to inject small amounts of food proteins in a grid pattern on your back to look for localized reactions, while the blood test can reveal an increase in the IgE allergy antibody in your system.

Airbrush have generally been available in two basic forms, gravity fed and siphon fed. Further, within these forms, a plethora of sizes of airbrushes are also available.
Gravity fed and siphoning airbrushes are generally used for different tasks. If a paint job requires a great deal of paint, the user generally must use a siphon fed airbrush as it allows for more paint to be available. If greater painting precision is desired, the user will generally choose a gravity fed airbrush as the lighter weight paint receptacle and the availability of all of the air to push paint, rather than sucking paint, allows more precise movements and accuracy. As a result of these limited uses of each type of airbrush, the user must buy both types of airbrushes if he wishes to do large and small jobs. In addition, if the user has need of different sizes of airbrushes, he must then buy the different sizes in both gravity and siphoning types. The result is a large collection of different size and type airbrushes which must be prepared and then cleaned.
A gravity fed airbrush generally has a receptacle or cup in which relatively small amounts of paint can be placed. The receptacle can generally be located anywhere above the point at which paint exits the airbrush and works by paint dripping into the airbrush. A siphon fed airbrush generally has a larger receptacle or paint jar attached below the paint exit point and generally has a tube connecting the paint jar with the airbrush. The passage of air over the end of the tube causes a negative pressure in the tube, which coupled with the positive pressure in the paint jar, causes the paint to be literally sucked, or siphoned, from the paint jar into the airbrush.
We have invented a novel type of airbrush that allows the use of one airbrush as both a gravity fed and siphon fed airbrush. In this way, only half as many airbrushes need be bought, prepared, used and cleaned to make a complete set. Further, if the user is doing a large job and then wishes to work with greater accuracy, the airbrush of the present invention may be easily converted from a siphoning airbrush to a gravity fed airbrush and vice versa.
In the illustrative embodiment, the airbrush is further provided with a paint intake on the front body and a trigger and air intake on the handle. When the front body is rotated, the paint intake can rotate from a siphoning position to a gravity feed position.
In accordance with the present invention, an airbrush is provided having a handle and a front body. The handle defines a first tubular cavity through which air may travel and the front body defines a second tubular cavity through which air may travel. The handle and front body also define a longitudinal axis. The front body is rotationally attached to the handle in such a way that the first tubular cavity is in communication with the second tubular cavity when the front body is rotated about the longitudinal axis of the airbrush with respect to the handle.

An airbrush couples to a pressurized air source and a media source, e.g., a liquid ink or paint media. The media intermixes with an air stream as it exits the airbrush in an atomized spray. Air brushes are versatile and popular tools in many fields. An airbrush may be modified in operation according to a variety of parameters to accomplish a variety of objectives. The amount of air pressure, amount of media introduced into the air stream, and the rate of movement for the airbrush in relation to the workpiece affect the resulting work, i.e., affect how the media appears as it comes to rest on the workpiece.
Fine line detail work, therefore, presents a challenge in airbrush design and use. Some airbrushes produce fine line detail. Unfortunately, the artist must move the airbrush quickly to preserve fine line detail as the media strikes the workpiece. If the artist does not move the airbrush quickly, fine line detail is lost in excess media buildup and overspray on the workpiece. Accordingly, only the most skilled airbrush artists can produce any meaningful fine line detail. Even such skilled artists, however, cannot make extensive and practical use of fine line detail due to the need to always move the airbrush rapidly. Because of such limitation, i.e., the requirement that the airbrush move at significant speed relative to the workpiece, fine line detail in airbrush work is generally not possible. Even with a limited ability to render fine line detail work by moving the airbrush at significant speed, conventional airbrushes have not and cannot allow elaborate or intricate fine line detail work.
Accordingly, there remains need for an affordable airbrush capable of providing fine line detail but at significantly lower speeds. By allowing fine line detail at lower speeds, i.e., speed of the airbrush relative to the workpiece, a greater number of artists can make use of fine line detail in their work and a greater variety of airbrush work becomes possible at even greater detail than previously possible using conventional airbrush designs. The subject matter of the present invention provides a fine line detail rendering ability for a conventional or typical airbrush moving at relatively low speed in relation to the workpiece.
The subject matter of the present invention is particularly pointed out and distinctly claimed in the concluding portion of this specification. However, both the organization and method of operation of the invention, together with further advantages and objects thereof, may best be understood by reference to the following description taken with the accompanying drawings wherein like reference characters refer to like elements.
The atomized media spray follows a conic pattern as it emerges from the airbrush nozzle. This conic pattern naturally carries significant overspray, especially when using relatively high air pressure. Given this conic spray pattern and inherent overspray, the airbrush naturally lacks an ability to focus the media spray. As a result, airbrush work typically includes a given amount of overspray and “fuzzy” rendering. Fine lines and distinct edges typically can only be achieved by use of shielding, e.g., a template held between the airbrush and the workpiece to prevent overspray on the workpiece.
A relatively expensive type of airbrush, i.e. the “turbine” model reciprocating needle by Paache AB, provides a degree of fine line detail work without requiring that the airbrush move rapidly. The cost, typically six to eight times that of an introductory-level conventional airbrush, makes this airbrush unavailable to most airbrush artists.
In accordance with the present invention, a conventional airbrush receives an attachment coupling to its spray outlet nozzle. The conventional airbrush output, i.e., atomized media, enters a chamber of the attachment. The flow of atomized media within the chamber is then diverted. The bulk of atomized media passes from the chamber through a bypass outlet. The remaining portion of atomized material, however, passes through an outlet nozzle at the distal end of the chamber as a fine line spray. In essence, the present invention focuses the atomized material more closely along parallel lines as opposed to diverging lines, i.e., as opposed to a conic pattern as found in conventional airbrush design. When applied to a workpiece this focused fine line spray provides fine line detail rendering without requiring rapid movement of the airbrush in relation to the workpiece.

Small airbrush is ideally suited for precision painting and other artistic endeavors. The small size and light weight of the equipment allows ease in holding and longer use before fatiguing the user’s hand. However, as a result of the small size needed, the airbrush, which includes a large number of very small precision parts, is generally difficult to manufacture and assemble, and is also difficult to disassemble for cleaning.
In order to clean thoroughly an airbrush constructed in this manner, the user would have to break the seal between the paint tip and the head, clean the parts and then reassemble the parts in the manner described above. Many users, without the materials, tools or skills to do this operation, were forced to return the paint tip and head assembly. This generally caused the user to be without the use of the airbrush for a considerable amount of time or necessitated the purchase of replacement interchangeable paint tip and head assemblies.
In many prior art air brushes the most precise and tiny parts are found in the crown. The crown comprises a head with a post connecting the head to the front body, a paint tip and a regulator. The post comprises a tube through which the paint needle and paint pass in the head. The paint tip, a tiny and highly specialized part, is screwed into the post and accepts a paint regulating needle. The paint tip comprises the final passage for paint prior to the mixing of the paint and air. In many prior art airbrushes, the paint tip is constructed with threads so that it can be screwed into the distal end of the post. The assembly of the paint tip to the airbrush head, via the post, further required the use of beeswax. The beeswax was heated and applied by a skilled technician to the threads of the paint tip so as to form a leak-proof seal of the walls of the post and the paint tip when the threads of the paint tip and post were inter-engaged. The head and paint tip assembly would then be attached to the front body of the airbrush.
In many larger model airbrushes, such as the CRESCENDO? 175T airbrush by Badger Air-Brush Co. of Franklin Park, Ill., this problem is obviated by the increased size of the device. In the CRESCENDO?airbrush, the paint tip is seated in the airbrush body and a head is attached to the body. The paint tip emerges through the head and is held to the airbrush body by the head. A regulator is then attached to the head. This three part system, paint tip, head and regulator, works well in larger air brushes.
We have discovered a novel four-part small airbrush that obviates the need for skilled re-assembly, sealing compounds or large sized parts and allows the use of a non-threaded paint tip that will not fall out when the regulating tip is removed for cleaning. We have also discovered that this four-part system can be substituted onto many prior art airbrush front bodies and handles thereby obviating the need for present airbrush users to purchase entirely new airbrushes. The substitution would give the user all of the benefits of the prior art airbrushes and provide all of the benefits described herein. Further, because the paint tip and the post, of the present invention, are not fixed together, better alignment between the paint tip and the regulating tip can be achieved and fewer posts may be bent or otherwise taken out of alignment.
In accordance with the present invention, an airbrush which comprises a front body through which air and paint are directed is provided. A head, having a tube known as a post, is removably attached to the front body. A paint tip and a regulator, removably attached to the head, are also provided. The regulator comprises a detachable holding ring and a regulating tip.
The paint tip is secured to the head by the holding ring when the paint tip is placed within the post and the holding ring is attached to the head. The regulating tip can be detached from the airbrush while the paint tip remains secured by the holding ring.
In the illustrative example, the paint tip and post are shaped so that their joinder produces a close fit. In this way, when pressure is applied through the holding ring, leakage of paint is minimized. Further, the illustrative example shows a crown design that can be used on prior art airbrushes, allowing the user to buy a replacement crown kit and obviating the need for the user to buy an entirely new airbrush.

The invention comprises the foregoing and other features hereinafter fully described and particularly pointed out in the claims, the following description and the annexed drawings setting forth in detail a certain illustrative embodiment of the invention, this being indicative, however, of but one of the various ways in which the principles of the invention may be employed.
Each pair of branch passages preferably forms a Y with the main delivery passage and terminate at a bore opening in the wall of a respective one of the bores in which the nozzle members move. The nozzle members each having a body including a transfer passage which has an inlet opening and a nozzle outlet opening, and the inlet opening is aligned with the corresponding bore opening when the nozzle member is moved into operative engagement with the mold and out of alignment when the nozzle member is moved out of engagement with the mold.
At least two nozzle members each have associated therewith a respective actuator for moving the nozzle member independently of movement of the other one of the two nozzle members. Preferably the manifold includes a manifold block in which said nozzle members are slidably movable, and each molding station comprises a clamping unit.
The object of the invention is to provide a molding changing device for a molding machine of the aforementioned type, which makes it easy to handle a mold without any additional means, such as a travelling crab, cranes, stacker trucks or the like.
According to another aspect of the invention, an injection molding machine comprises a plurality of molding stations for respective molds, an injection unit, and a manifold assembly. The manifold assembly includes an inlet for receiving molding material from the injection unit and a plurality of nozzle members each including a transfer passage and being movable into and out of operative engagement with a mold in the respective molding station.

Known rubber injection molding machine commonly include a press or clamping unit for a mold and an injection unit for injecting uncured rubber into the mold. The mold typically includes upper and lower mold halves or parts which are heated and clamped together under high pressure by the clamping unit. The injection unit has an injection nozzle through which the uncured rubber is injected into the mold for cure under pressure and high temperature conditions. Rubber injection molding machines of various press clamping forces and injector shot capacity are manufactured by U.S. Molding Machinery Company of Mentor, Ohio.
During the curing and/or product removal phases of the machine cycle, the injection unit may be recharged for the next machine cycle. The recharging time often is considerably shorter than the time needed to cure the rubber and remove the cured rubber product. Consequently, the injection unit may be idle for a substantial portion of the total cycle time. As has been recognized in the art of rubber injection molding for some time, advantage can be taken of this idle time in relation to one mold by using the injection unit to inject a charge into another mold or molds.

As has been recognized in the art of rubber injection molding for some time, advantage can be taken of this idle time in relation to one mold by using the injection unit to inject a charge into another mold or molds.
In a typical machine cycle, the mold is clamped in the clamping unit and then uncured rubber is injected into the mold by the injection unit. The rubber is then cured (vulcanized) in the mold for a prescribed time after which the press is opened for removal of the molded rubber product from the mold. After this the press is again closed to commence another machine cycle and production of another molded rubber product.
According to another aspect of the invention, an injection molding machine comprises a plurality of molding stations for respective molds, an injection unit, and a manifold assembly. The manifold assembly includes an inlet for receiving molding material from the injection unit and a plurality of nozzle members each including a transfer passage and being movable into and out of operative engagement with a mold in the respective molding station. Preferably the manifold includes a manifold block in which said nozzle members are slidably movable, and each molding station comprises a clamping unit.
One known rubber injection molding machine includes a single injection unit which may be shared by up to six press units in respective stations of the machine. The press units are arranged in a row and the injection unit is shifted laterally from station to station thereby sequentially to inject a charge into the mold clamped at each station. This technique of moving the injection unit from one station to another is subject to several drawbacks. One drawback is the relatively high cost and complexity of the mechanism and controls needed to shuttle the injector unit between stations. The moving injector unit also creates concerns about misalignment between the injection unit and the molds which may cause such problems as leakage and excessive wear.
According to the invention, a multi-station rubber injection molding machine comprises plural molding stations for respective molds, a rubber injection unit, and a manifold assembly for selectively transferring uncured rubber from the rubber injection unit to a mold in any one of the molding stations. Actuators are provided for moving respective ones of the nozzle members between the first and second positions independently of movement of the other nozzle members.
