Title: Use of cationic preservative in food products
Inventor: URGELL BELTRAN JOAN BAPTISTA
IPC: A23L29/231
Filed: 2001-10-25
Granted: 2010-07-06
Abstract: This invention relates to a novel use of cationic preservatives and preparations according to this novel use. A cationic preservative derived from lauric acid and arginine, in particular, the ethyl ester of the lauramide of the arginine monohydrochloride, hereafter named LAE, can be used for the protection against the growth of microorganisms. The chemical structure of LAE  is described in formula (I). LAE and related compounds are particularly suitable to be used in the preservation of all perishable food products. It is preferred to dissolve the compound directly before use in one of the following preferred solvents of food grade: water, ethanol, propylene glycol, isopropyl alcohol, other glycols, mixtures of glycols and mixtures of glycols and water.  If the treatment shall be performed at a specific pH value the use of a corresponding buffer solution may be recommendable. The composition optionally comprises auxiliary components and excipients. Such auxiliary components and excipients can be thickening agents (e.g. xanthan gum, guar gum, modified starches), anti-foam agents (e.g. dimethylpolysiloxane, silicon dioxide), products to obtain the optimal pH value (e.g. phosphates, tartrates, citrates, lactates), colouring agents (e.g. curcumin, tartrazine, erythrosine), and aroma products. It is preferred, that the preservative composition comprises LAE in an amount of from 0,0001 % to 1 % by weight relative to the whole weight of the preservative composition. It is particularly preferred to use the inventive composition for the preservation of meat products, like for instance meat, poultry products, fish, crustaceans, vegetables, greens, emulsions, sauces, confectionery, bakery, pre-cooked meals, ready-to-serve meals, dairy products, egg-based products, jams, jellies, beverages, juices, wines and beers.

Title: Gelatin coated sand core and method of making same
Inventor: HERREID RICHARD M
IPC: B22C9/14
Filed: 2002-03-13
Granted: 2008-05-20
Abstract: In a method of making a molded article for use in a casting process, sand particles are mixed with protein and water to effect a coating of protein on the sand particles. Then, the protein coated sand particles are dried and blown into a pattern mold to form a molded article without active cooling of the coated sand particles. Steam is then passed through the molded article to hydrate and melt the protein, thereby forming bonds between contiguous sand particles. Finally, hot, dry air is passed through the molded article to harden the protein bonds between the contiguous sand particles. This forms a protein coated sand core for use in casting molten metals.

Abstract: A method of attaching a tubular (22) to an existing tubular (10) in a well without reducing the inside diameter of the well is described. A shoe (14, 19, 28, 32, 42, 48, 58, 66) is attached to the lower end of the existing lowermost casing or tubular, generally prior to the casing being cemented or otherwise secured in the wellbore. The shoe has a diameter larger than the inside diameter of the casing or tubular to which it is attached. Subsequently, a liner is run in until its top end is in the enlarged diameter region of the shoe. A hanger can be optionally used. The liner is expanded into the enlarged diameter so that the net result is that the inside diameter in the wellbore is not reduced by the addition of the liner.

Abstract: An efficient and reliable installation for a water tight and an aesthetically pleasing transition between adjacent building or construction components is provided with use of a backer rod material for placement between adjacent building or construction components for subsequent caulking. A closed cell foam backer rod material includes a terminal end portion of the backer rod joined to a remainder thereof by a frangible connection or perforated joint. The frangible connection or joint in the backer rod is nonlinear or arcuate-shaped to provide a crown- shaped or convex-shaped backer rod surface to receive the caulking compound to finish the joint. After the backer rod material is installed into the joint, the terminal end portion of the backer rod is removed by being torn along the frangible joint. A bead of caulk or similar finishing material is applied in the recess to provide a smooth and aesthetically pleasing transition from the frame to the wall. The convex or crown shape of the exposed surface of the backer rod material allows for and promotes integrity of the caulking compound during shifting, expansion and/or contraction of the adjacent building components relative to each other.

Abstract: A movable belt conveyor system for a leach pad for use for sulfidic copper ore, where favorable conditions are to be generated for leaching out the copper by a slight compaction of the ore piled up into a dump for the microbiological leaching technology. The movable belt conveyor system of a length of up to several km is composed of a plurality of smaller belt segments, comprising a tail segment (70), standard segments (71 l-n) and a head segment (72), as well as a traveling tripper (8). To prevent the loading by these individual components from being excessively compacted by the weight of the device during multiple travel over the dump during the moving process, the belt drives with the driving drum are accommodated in the tail element (70), which is supported on the soil next to the leach pad. In addition, the traveling tripper (8) is designed as an independent unit with the belt drums, additional belt drives and the belt-tensioning means, which unit is autarchically displaceable on a caterpillar-type moving gear (85) of its own. Due to the moving of the belt on the caterpillar-type moving gears of the standard segments (71 l-n), on the head segment (72) and on the traveling tripper (8) as well as due to the absorption of the weight of the tail segment (70) by the transfer carriage (6), the surface pressure acting locally on the dump is reduced and the compaction of the ore on the dump due to being traveled over by the belt conveyor system remains low. Traveling over with a moving device, which frequently happens with the use of a moving caterpillar, is eliminated.

Abstract: The present invention discloses a method for recombining catalytic hydrocarbons, which is fed onto the main catalytic fractional column for fractionating to get gasoline, diesel and a medium fraction. The medium fraction or the mixture of medium fraction and gasoline fraction is divided into aromatics and nonaromatics after the processing of aromatics extraction.  Then the aromtics is fractionated to get high octane value gasoline, which is blended with the former gasoline fraction to increase its octane value, on the other hand, the nonaromatics is fractionated to get diesel, which is blended with the former diesel fraction to increase its cetane value and yielding.  Compared with the prior art, the method with less investment and lower production cost is not limited by raw material and also can increase the final production items.
