Abstract: An internal combustion rotary engine has a chamber defined by a chamber wall and a rotor valve body in three locus-sealing contact with the chamber wall to define a series of three subchambers including a first subchamber for sequential compression, transfer, and combustion of a fuel mixture from a chamber fuel mixture intake and for exhausting combustion products through a chamber exhaust outlet. The rotor body defines a first bodily internal path for fuel mixture travel from the intake to the first subchamber for compression and combustion to combustion products, and a second bodily internal exhaust travel path between the combustion products in the first subchamber and the chamber exhaust outlet for exhausting of the combustion products. The chamber and rotor cooperate to transfer compressed fuel mixture past the rotor within the first subchamber. The rotor further defines a sealing and sliding valve structure with the chamber wall for controlling intake into and exhaust from the first subchamber.

Abstract: Horse hoof protection is obtained by incorporating a synthetic organic resin such as a urethane resin in the volume defined by the horse hoof bottom wall, suitably covered with a web fixed to the hoof bottom wall that is adhered to the resin. The resin protection is suitably free flowing into place, conforms to the contours of the hoof bottom wall, and adheres to the wall when cured. The protection by the resin is resilient and softer than the hoof wall and acts to cushion the hoof against shock.

Abstract: Horse hoof protection is obtained by incorporating a urethane resin reaction product of low viscosity sides A and B which react rapidly to gel in a few seconds while filling the interstices or the horse's hoof and have when reacted a low hardness of 40 to 80 Shore A to cushion the hoof.

Abstract: The medicament of the present invention and its process of manufacturing employs a caplet or tablet core with a clear or single color uniform covering which can be applied either through an enrobing process, by spraying or by a single dip-coating step. The core itself can have a first color or be colorless, and its clear or single color covering has the outer surface of one end or one side colored by a suitable dye to provide a two-color appearance. The dye can be applied by dipping or spray painting with a suitable jet-spraying apparatus. In a preferred embodiment, the covering is of a clear gelatinous material.

Abstract: Composition, method, and products for the environmental protection of integrated circuits comprising a robotically dispensible, wave solderable, low moisture absorbing urethane polymer reaction product of an aliphatic isocyanate, a flexibilizing low molecular weight rubbery polymer having isocyanate reactive hydroxyl terminals, and a diamine arranged to bodily encapsulate the integrated circuit within a dam of thixotropic version of the same polymer, the encapsulation being free of popcorning response to rapid heat rise after high humidity conditioning and otherwise superior as an IC encapsulant.

Abstract: A medicament includes a caplet having a peripheral land which is inserted into mating capsule shell halves each with internally formed recesses defining external peripheral lands which align when the shell halves are fitted over the caplet. In one embodiment of the invention, the internal diameter of the capsule shells is selected such that the caplet will fit within the capsule cell regardless of its orientation, while in another embodiment the caplet land mates with the internal recesses of the capsule shells. In a preferred embodiment of the invention, the capsule shells have different lengths and diameters such that one overlaps the other and can be sealed.

Abstract: Structure, composition and method in which a fiber reinforcement is impregnated with an interpenetrating network of a light cure resin and a thermosetting resin which are independently curable, enabling autobody component repair, electronic assembly bonding, etc. by selective cure first of one or the other resin, and the support against fluid flow of the uncured resin by the first cured resin.

Abstract: Addition of a polyurethane or polyurea polymer to each part of a particulate filled precursor of a two-part resin stabilizes the filler against settling from suspension, and provides thixotropic response when the precursors are expressed from a container.

Abstract: Circuit board devices are provided based on use of high temperature superconducting ceramic polymers comprising high temperature superconducting ceramic powders distributed in electrically insulative organic polymers which are thermosetting by reaction of a two-part liquid mixture or by catalytic or photoinitiation of a one-part liquid. The ceramic domains transmit their superconductivity across the insulating barriers of organic polymers enabling formation of superconductive lines and superconducting bonds to electronic devices to be adhered to circuit boards, and providing superconducting circuitry.

Abstract: An improvement in producing aqueous slurries of wool pulp made by the Stora process is disclosed. The improvement consists of adding to the slurry from 1 to 5 percent of isatoic anhydride, based upon the weight of the pulp. It has been found that the properties of paper made from the pulp, without beating, are improved, and that the time required for beating the pulp to a given degree of freeness is shortened as a result of the presence of the isatoic anhydride in the slurry.

Abstract: This invention relates to a process for preparing benzoxazines and more particularly 2-substituted-4H-3,1-benzoxazine-4-ones, obtained by reacting at least at about room temperature in the presence of an effective amount of a tertiary amine an isatoic anhydride with an acylating compound consisting of either a carboxylic acid anhydride or an acyl halide.

Abstract: A method for producng N-monosubstituted-2,3- and 3,4-pyridinedicarboxamides and 2,3-pyrazinedicarboxamides, which is accomplished by reacting corresponding imide precursors with ammonia or primary or secondary amines in the presence of a suitable solvent such as anhydrous alcohols, ethers, dimethylformamide and the like.
