Abstract: An article of armor includes a friction material operative to prevent penetration of a ballistic projectile. The armor is also operative to prevent penetration of a plurality of ballistic projectiles at a single point of impact. The armor may include a backing, or a facing, or may comprise an intermediate layer between a backing and facing in any combination. The armor of the invention applied directly to or attached to an article to be armored so as to cover all or any portion of the article. The backing and facing may include a friction material or a non-friction material. The friction material is a composite of a resin binder agent, a fibrous support structure, a friction modifier system, and a wear system.

Abstract: A method and system for increasing optical instrument calibration and prediction accuracy within and across different optical instrument platforms can comprise two main submethods or routines. The first routine can include one for correcting differences among optical instruments of different model types regardless of the manufacturer and correcting differences among optical instruments of the same model type. The second main routine or sub-method can include one for analyzing new samples of a product over time and maintaining prediction accuracy as compared to a reference method over time. The first routine can include a “TRANS” procedure, a “MIN” procedure, and checkcell tests. The second main routine provides techniques on how a product database can be cleaned, condensed, and expanded automatically as it is used by one or more different optical instruments.

Abstract: Provided are certain chemical entities, and methods of use to modulate skeletal myosin, skeletal actin, skeletal tropomyosin, skeletal troponin C, skeletal troponin I, skeletal troponin T, and skeletal muscle, including fragments and isoforms thereof, as well as the skeletal sarcomere, and methods of use in the treatment of muscle weakness and/or cachexia, as part of a rehabilitation or conditioning exercise regimen, or in the treatment of fraility, post-polio syndrome, obesity, sarcopenia, wasting syndrome, muscle spasm, and other indications.

Abstract: An improved continuous crumbing machine for recycling rubber tires and other materials such as polyethylene containers, gypsum, hardboard, tin cans, glass jars and bottles. The device comprises a pair of rotating rolls having negative rake teeth of interlocking sprocket design formed on the outer periphery of each roll. The materials to be fragmented or crumbed are fed between pairs of rotating rollers having negative rake teeth. A plurality of stages of rotating rollers are placed in series to obtain the desired particle size.

Abstract: Post consumer recyclable plastics are combined with a ethylene-octene copolymer and a polyamide to prepare a resin composition that can be used in conventional molding processes to fabricate new and useful plastic articles of manufacture.

Abstract: Waste rubber containing carbon black is broken down in size into small pieces, purged of air and then fed into a retort, likewise purged of air and continuously rotated or oscillated about its longitudinal axis. The retort is maintained at a temperature ranging between 275.degree. F. and 1000.degree. F., and preferably ranging between 500.degree. F. and 850.degree. F., to produce rubberized carbon black consisting of particles of carbon, each particle encapsulated in a sphere of rubber of 1-60 microns in diameter.Rubberized carbon black can be compounded with virgin rubber or polymer such as scrap high density polyethylene or both virgin rubber and polymer, and can then be formed into various shapes having useful and valuable physical, mechanical and thermal properties.

Abstract: An automated loading system for nuclear reactor fuel elements utilizes a gravity feed conveyor which permits individual fuel pins to roll along a constrained path perpendicular to their respective lengths. The individual lengths of fuel cladding are directed onto movable transports, where they are aligned coaxially with the axes of associated handling equipment at appropriate production stations. Each fuel pin can be reciprocated axially and/or rotated about its axis as required during handling steps. The fuel pins are inserted as a batch prior to welding of end caps by one of two disclosed welding systems.

Abstract: A welder for automated closure of fuel pins by a pulsed magnetic process in which the open end of a length of cladding is positioned within a complementary tube surrounded by a pulsed magnetic welder. Seals are provided at each end of the tube, which can be evacuated or can receive tag gas for direct introduction to the cladding interior. Loading of magnetic rings and end caps is accomplished automatically in conjunction with the welding steps carried out within the tube.

Abstract: An enlarged funnel is releasably mounted at the open end of a length of cladding by an encircling length of shrink tubing which securely engages outer surfaces of both the funnel and cladding. The shrink tubing overlaps an annular shoulder against which pulling force can be exerted to remove the tubing from the cladding. The shoulder can be provided on a separate collar or ring, or on the funnel itself.

Abstract: A welder for automated closure of fuel pins by a gas tungsten arc process in which a rotating length of cladding is positioned adjacent a welding electrode in a sealed enclosure. An independently movable axial grinder is provided in the enclosure for refurbishing the used electrode between welds.

Abstract: A game of chance simulating the betting in horse racing. A game board contains the numbers of hypothetical horses, and indications of odds paid on each horse in each position of that horse in the race, as Win, Place and Show. A wheel or roulette type indicator, includes a dial with the numbers of the horses arranged in a circle, and a rotatable arrow or spinner which upon being rotated or spun, and after stopping, indicates the horses in the particular race concerned. The spinner has three arms, each indicating a respective one of the horses as to its position, i.e., whether Win, Place or Show. A combinations chart is included, which shows the combinations of the positions of the first three horses in each race, that is, for each position of stopping of the indicator, a predetermined combination of horses constitute the first three in that race.

Abstract: A composition for coating the refractory liners of ladles and troughs for pouring and/or conveying molten metals comprising an aqueous dispersion containing finely divided zirconia, a colloidal silica, finely divided mica, finely divided zircon, finely divided bentonite and, optionally, an inert coloring agent. The coating composition is capable of re-bonding fractured liners and the resulting coating prolongs the effective life of the liner and exhibits superior reflectivity, causing the molten metal to retain its heat which facilitates better pouring.

Abstract: A process for solvent extraction of higher aromatic hydrocarbon oils with N-methyl-2-pyrrolidone wherein N-methyl-2-pyrrolidone is separated from a solvent-extract mix in a series of distillation steps with recirculation of a portion of a partially stripped extract mix from an intermediate distillation step to the extraction step to improve the solvent-oil ratio in the extraction step and conserve energy as compared with conventional processes in which the solvent power of N-methyl-2-pyrrolidone is moderated by incorporating water in the solvent.

Abstract: A composition for coating the molding surfaces of molds for casting metal parts comprising an aqueous dispersion containing finely divided zirconia, a colloidal silica composition, finely divided mica, finely divided zircon, finely divided bentonite and, optionally, an inert coloring agent. While capable of protecting the molding surfaces against high temperature molten metal and producing castings having substantially defect-free surfaces, the coating composition provides cleaner castings by partially attaching to the casting and spalling off as the casting cools.
