  • Patent number: 5159989
    Abstract: An automatic leveling system for a four-wheel vehicle system having outrigger assemblies at each of the four corners of the vehicle chassis and in which each outrigger assembly has an outrigger pad and a hydraulic cylinder for moving the pad downwardly and upwardly relative to the ground. The leveling system includes a low-pressure high-flow source of hydraulic fluid which is connected for one-way flow into the head ends of all four of the cylinders to lower all pads to the ground and then maintain them in contact with the ground. A level sensor senses the relative levelness of the right front and left rear corners of the vehicle and high-pressure low-flow hydraulic fluid is connected to the head end of the cylinder at the lower of those two corners to raise that corner of the vehicle relative to the ground.

  • Patent number: 5157942
    Abstract: An improved regenerative absorption refrigeration cycle having a high COP and a commercially practicable pumping system. In the basic cycle, an ammonia/water solution is boiled in an externally-heated generator (11). The boiled-off ammonia vapor is cooled (14) in a regenerator (16), condensed (28), expanded to low pressure (32), and boiled in an evaporator (34) to extract heat from fluid circulating to and from a cooling load (41). The low-pressure liquid ammonia returns (46) to the regenerator (16) and is absorbed back into the low-pressure water from the generator. The solution is then cooled in a low-pressure absorber (50), pumped (53) to a high-pressure conduit (57) which is heated by the regenerator heat before going back to the generator 11. The improved cycle uses at least one intermediate absorber stage 60 to absorb more ammonia vapor (69, 71) into the solution coming from the lower pressure absorber (50) to produce a cooled solution of higher ammonia concentration.

  • Patent number: 5143737
    Abstract: The present invention relates to an improved method for the modification of a food for a ruminant mammal such that the mammal will produce a modified milk fat or meat fat which method comprises:(a) producing an emulsion of(i) a non-toxic food substance to be encapsulated; and(ii) an acid sensitive nontoxic crosslinkable material which will surround and encapsulate the substance with the proviso that no added crosslinking chemical is present in the emulsion; (b) subjecting the emulsion to reaction conditions which crosslink the crosslinkable material and encapsulate the substance. Specifically, the method is useful to encapsulate emulsified unsaturated fatty acids with a natural protein such as whey protein concentrate containing a reducing sugar, such as lactose, with crosslinking and encapsulating using the Maillard browning reaction. Cattle sheep or goats feed the modified food produce a higher level of unsaturated milk fat and meat fat.

  • Patent number: 5141627
    Abstract: The present invention relates to a group of organic chelators whose affinity for calcium ion in solution is increased by electromagnetic radiation. Specifically, the chelators are related to BAPTA and utilize the addition of an electron-withdrawing group (e.g., diazocarbonyl) to a ring of BAPTA, para to the amino group. Photochemical rearrangement of the diazoacetyl group converts the group to the electron-donating carboxymethyl group, causing the calcium ion efficiency to increase 25 to 50 fold. These chelators when incorporated into rat fibroblasts either by microinjection or by incubation as the membrane-permeable, enzymatically-labile tetraacetoxymethyl ester and flash-photolyzed cause a drop in intracellular free calcine ion to or below resting valves of about 10.sup.-7 M. These chelators are used to generate controlled fast removal of intracellular free calcium ion to mimic or modulate a number of important cellular responses, especially in nerve or muscle.

  • Patent number: 5106601
    Abstract: Exhaust gases are treated to remove NO or NO.sub.x and SO.sub.2 by contacting the gases with an aqueous emulsion or suspension of yellow phosphorous preferably in a wet scrubber. The addition of yellow phosphorous in the system induces the production of O.sub.3 which subsequently oxidizes NO to NO.sub.2. The resulting NO.sub.2 dissolves readily and can be reduced to form ammonium ions by dissolved SO.sub.2 under appropriate conditions. In a 20 acfm system, yellow phosphorous is oxidized to yield P.sub.2 O.sub.5 which picks up water to form H.sub.3 PO.sub.4 mists and can be collected as a valuable product. The pressure is not critical, and ambient pressures are used. Hot water temperatures are best, but economics suggest about 50.degree. C. The amount of yellow phosphorus used will vary with the composition of the exhaust gas, less than 3% for small concentrations of NO, and 10% or higher for concentrations above say 1000 ppm.
