Abstract: The present invention provides a chemical product having magnesium oxide, magnesium hydroxide or both and being applied as a preservative for animal or animal parts containing fats, proteins or both. The animal or animal part are meat, meat by-product, blood, blood products and animal feed. The preservative may also be combined with an anti-oxidant (such as Vitamin E, i.e. Tocopheryl Acetate), sodium hydroxide, potassium hydroxide, calcium hydroxide, calcium oxide or sodium bicarbonate. The preservative is used as a neutralizer of acids in degradation reactions of proteins and as a neutralizer of acids in degradation reactions of fats. The method of application of the preservative for neutralizing acids during degradation reactions of proteins and for neutralizing acids during degradation reactions of fats is also presented. By stabilizing pH of acidic media, degradation reactions of fats and proteins are slowed.

Abstract: The present invention relates to portable flexible fillable barriers that are used to restrain the flow of fluids and to serve as reservoirs, containers (for solids as well) and embankments. The portable flexible fillable barrier is collapsible upon itself into a smaller size, facilitating storage and transportation, and is self-opening from the collapsed state. The portable flexible fillable barrier has a flexible fillable wall comprising an upper portion, a lower portion, a top end, a bottom end, several sides, a number of openings and a supporting frame that has inner structural cells with cell openings and an enclosing flexible membrane. Numerous portable flexible fillable barriers may share a fluid path formed by holes in shared side walls or formed by tubes leading from one portable flexible fillable barrier to another.

Abstract: The subject invention provides a gas turbine engine in which a cooling system is utilized to lower the temperature of light hydrocarbon liquid fuel before the fuel is injected into the combustors. Specifically, the fuel cooling system is deployed in the fuel delivery system upstream of the combustors to lower the temperature of the liquid fuel below the flash point temperature, preventing phase change and premature combustion. In the preferred embodiment, the cooling system is a closed loop system comprising a heat exchanger, a containment reservoir, and a refrigeration unit. Brine is circulated within the loop, such that cooled brine is passed into the heat exchanger to act as a heat sink for the light hydrocarbon flowing therethrough. Warm brine exiting the heat exchanger is directed into the refrigeration unit for cooling before being collected and stored in the containment reservoir. The cooled light hydrocarbon exits the heat exchanger and is injected into the gas turbine engine.

Abstract: An improved additive eductor for supplying additives, including foam concentrates and thixotropic foam concentrates, into a hand line or waterline for supplying a nozzle used for fire fighting operations wherein the additive eductor can be operated in either eductive or non-eductive by-pass mode and further comprising in a prefered embodiment a back-flow preventative metering valve attached to a additive port.

Abstract: A tool for enhancing the impact of either an upward or downward blow delivered by a single-acting jar to an object stuck in a well bore includes first and second tubular members telescopically arranged and vertically reciprocable with respect to one another to form an annular space between them, upper, lower and intermediate seal rings between equal diameter portions of the tubular members, and a ring carried by the second tubular member within the annular space between the intermediate seal ring and each of the upper and lower seal rings to form upper and lower pressure and charging chambers on the opposite side of each ring, the rings being of such construction that, with each charging chamber filled with a compressible fluid, movement of the second tubular member in one vertical direction will compress the fluid in the upper and lower pressure chambers and thus enhance the impact of a jar in the same vertical direction, and permit flow therepast, in response to movement of the second tubular member in the
