Abstract: The present invention is for a three-dimensional device for teaching the important structures and functions of an organ in a body in order to increase an individual's understanding of the organ and possible medical problems involving the organ. An individual places the glove-like or mitten-like three-dimensional device on his hand and positions his hand in such a way as to accentuate the three-dimensional aspect of the device, then places that hand on his own body to indicate the general location of the organ of interest.

Abstract: Thermosetting, bottom-applied polymeric anti-reflective coatings exhibiting high optical density, rapid plasma etch rates, high solubility in preferred coating solvents, excellent feature coverage, and improved stability in solution are disclosed. The principal component of these new anti-reflective coatings is a polyester resin produced by the reaction of one or more difunctional aliphatic carboxylic acids with a stoichiometric excess of a di- and/or a trifunctional aliphatic primary alcohol, wherein at least one of the dicarboxylic acids may contain a reactive methylene (--CH.sub.2 --) group. The resulting polyester resin reaction product is further modified by attaching light-absorbing groups to some or all of the reactive methylene groups (if present) and/or hydroxy groups present on the resin. The dye-attached polyester resin is combined with an aminoplast crosslinking agent and acid catalyst in a suitable solvent system to form the final anti-reflective coating.

Abstract: The invention is a mechanism for the streamwise deployment of an aircraft trailing or leading edge flap. The mechanism connects the spar and flap. There are a pair of swivel links which pivotally connect the spar to the flap. There are also a pair of slaving mechanisms which rotationally connect the spar to the flap by spherical bearings. A linear flap actuator initiates the combined pivotal and rotational action from the spar which translates into a single downward and rearward motion of the flap.

Abstract: A hybrid-propulsion car system having one axle driven by an internal combustion engine and another axis driven by an electric motor. The waste heat of the internal combustion engine is absorbed by the engine cooling fluid, and is then heat exchanged with an evaporative fluid in a closed circuit. The evaporative fluid is vaporized by the heat of the engine cooling fluid in order to drive an expander which in turn drives an electric generator. The electric generator supplies current to a storage battery and to the electric motor.

Abstract: A hydro injection system for generating steam from the heat exchanged between a stream of hot combustion gases and a countercurrent flow of warm water sprays which contact hot tubes transporting the hot combustion gases is disclosed. The system comprisesi. a continuous supply of hot combustion gases and means for propelling the gases through the system;ii. a continuous supply of cold water and means for warming said cold water prior to steam generation;iii. a pressure vessel means for conducting the heat exchange; andiv. a condensate receiver means for recirculating and equilibrating water in the system.

Abstract: A photolithographic composition having improved processability and which eliminates the need for inter layering multiple special purpose coatings in the production of micro-electronic devices is surprisingly made possible by selective dissolution of poly(vinylpyridine) and an effective light attenuating material in critical solvents.

Abstract: Pentaerythritol co-esters derived from pentaerythritol, (3-alkyl-4-hydroxyphenyl)-alkanoic acids and alkylthioalkanoic acids or lower alkyl esters of such acids are useful as stabilizers of organic material normally susceptible to oxidative and/or thermal deterioration. The co-esters are advantageously prepared by transesterification of such esters with pentaerythritol. Preferred co-esters are (I) pentaerythritol tris[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]-mono[3-n-do-decylthi opropionate] and (II) pentaerythritol bis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]-bis[3-n-dodecylthiopr opionate]. The co-esters are especially useful in stabilizing applications for which physical mixtures of (i) (3-alkyl-4-hydroxyphenyl)alkanoic acid esters of polyols with (ii) polyalkanol esters of alkylthioalkanoic acids have heretofore been proposed.

Abstract: Disclosed are stabilized linear low-density polyethylene (LLDPE) compositions containing a stabilizing amount of a ring-substituted N-acyl-para-aminophenol. In a preferred embodiment, the latter compound is N-stearoyl-2,6-di-t-butyl-4-aminophenol.

Abstract: The ethanolamine salt of N-nitrosophenylhydroxylamine ("NPHA") is effective as a polymerization inhibitor for ethylenically unsaturated monomers. The ethanolamine salt can be prepared by reacting ethanolamine with the ammonium salt of NPHA. Advantageously, the ethanolamine salt is soluble in high concentrations in water and a variety of polar organic solvents.

Abstract: Disclosed is a process for preparing a coated-particle salt substitute composition wherein a flow of a gaseous medium is passed upwardly through a bed including potassium chloride particles at a velocity more than sufficient to form and maintain a fluidized bed of the particles. A spray of an aqueous solution including maltodextrin is introduced into the fluidized bed below its upper surface to form a coating of the solution on the fluidized particles. The velocity is sufficient to also establish a particle-flow zone above and adjoining the upper surface of the fluidized bed wherein a substantial portion of the coated particles are propelled out of the fluidized bed on a flow path extending thereabove and returning thereto.
