Abstract: There is described a floatable incendiary composition consisting essentially of magnesium powder, an oxidizer and an elastomeric polysiloxane which serves as a binder the amount of polysiloxane being sufficient to bind together the other components of the composition. The compositions are rendered floatable on the surface of water by incorporating into them a quantity of hollow microballoons in sufficient amount to lower the specific gravity of the composition concerned to less than 1.

Abstract: Suppression of convulsions in warm-blooded animals is accomplished by administration of phenylsilanes of the formulas 0R.sub.2 SiX, 0RSiX.sub.2, 0SiX.sub.3, 0.sub.2 RSiX, and 0.sub.3 SiX in which R is an alkyl or alkenyl group and X is a hydroxyl group or one of several readily hydrolyzable radicals, such as the methoxy group. It should be understood that where there is more than one R or one X group in a composition, they need not be the same species.

Abstract: A solar energy collector is made up of a first flat flexible sheet preferably of silicone, and a first sinuous sheet also preferably of silicone, sealingly adhered to the first sheet along a plurality of spaced parallel lines to provide a series of substantially parallel ducts which carry a liquid heat transfer medium. Either the first flat sheet or first sinuous sheet incorporates solar energy absorbent material. A backing member which may include a sheet of reflective foil and a layer of foam insulation is adhered to the opposite side of the first sinuous sheet to form a plurality of substantially parallel air channels under the ducts. Desirably, a solar window which includes a second sinuous sheet with a second flat sheet adhered to the upper amplitudes thereof is adhered to the first flat sheet along the lower amplitudes to space the second flat sheet from the first flat sheet thereby providing a multiplicity of insulative air channels.

Abstract: There is described an incendiary composition consisting essentially of by weight 20-40 percent magnesium powder, 30-60 percent metallic oxide and the remainder of elastomeric polysiloxane which serves as a binder the amount of polysiloxane being at least 10 percent. A second type of composition consists of 20-50 percent magnesium powder, 20-30 percent polytetrafluoroethylene in particulate form, and the remainder of elastomeric polysiloxane. A third type of composition consists of mixtures of the first and second types in proportions according to the desired specific gravity of the incendiary.

Abstract: A solar energy collector is made up of a plurality of flexible sheets separated by a plurality of extruded flexible spacer members adhered to the sheets in parallel spaced relationship forming channels between the spacer members. The bottom sheet or middle sheet is light absorbing while the top sheet or sheets are light transmitting and all of the sheets and spacer members are desirably formed of silicone rubber or resin, the sheets being reinforced with glass fiber mesh if desired.

Abstract: A penile implant formed of a soft silicone rubber having a bulbous distal end which tapers to the proximal end and has a longitudinal groove formed on the ventral side which notches the proximal end.

Abstract: This is a method and apparatus for machining a flexible silicone contact lens which utilizes a moving, flexible abrasive tape bearing against the rotating lens to accomplish the desired result. The tape travels in a transverse direction across the lens and may be oscillated to provide a more uniform finish.

Abstract: This application describes a cross-head for directing flowable polymeric materials 90.degree. from the axis of an extruder or similar pressure source and providing substantially uniform pressure patterns at the cross-head output. This is accomplished by dividing and subdividing the stream entering the cross-head, each subdivision taking place on an axis of pressure symmetry and each substream being twisted 90.degree. before reaching its next point of subdivision. The subdivision and twists are accomplished by mounting twisted pieces of flat bar stock in the conduit carrying the stream or substream, each piece having its input end positioned on the axis of symmetry of the stream at the point of stream division.

Abstract: Method for making elongated structures such as furnace tubes having at least one flat side from vapor deposited silicon or silicon carbide using a graphite mandrel having a plurality of elongated edge-mated elements held in place by end collars to which an electrical power source is connected. Rectangular tubes can be sawed apart to produce flat plates if desired.

Abstract: Silicon semiconductor device array, e.g. solar cell device or array of devices; formed from bulk silicon deposited in the form of columnar crystallites bounded by substantially vertical grain boundaries. Junctions are formed across crystallites and along grain boundaries. The grain boundaries are made substantially non-conductive by diffusion from one side of the sheet. P.sup.+ and n.sup.+ layers are provided as contact areas for electrodes. Deposition of silicon takes place directly from decomposition of silicon-containing vapors onto a non-silicon substrate sheet.

Abstract: A wide dispersion incendiary device such as artillery round, bomb, or grenade in which a high explosive charge within a casing has imbedded therein a plurality of hollow metallic objects such as balls. The hollows communicating with the exterior of the objects and being filled with incendiary material which is ignited by detonation of the high explosive. The incendiary material is a mixture of silicone rubber, powdered magnesium, and an oxidizing agent.

Abstract: An incendiary device such as artillery round, rocket warhead, bomb, or grenade in which a high explosive charge within a casing has imbedded therein a plurality of balls of incendiary material which is a mixture of silicone rubber, powdered magnesium, and an oxidizing agent. The balls are ignited by detonation of the high explosive and are designed to continue burning during dispersion caused by said detonation.

Abstract: An incendiary fragmentation device such as artillery round, bomb, or grenade, in which a high explosive charge within a casing has imbedded therein a hollow cylindrical body of frangible incendiary material which is ignited by detonation of the high explosive. The frangible incendiary material is a mixture of silicone rubber, powdered magnesium, and an oxidizing agent.

Abstract: This is an elastomeric safety insert for a pneumatic tire assembly. The insert when installed has a toroidal configuration and has protuberances extending therefrom to space the body portion of the insert from the rim and tire casing, permitting the insert to dynamically balance itself when the tire is rotated.

Abstract: There is described herein a mold injection adapter for use with low viscosity polymers comprising a housing adapted to be urged into sealing relationship with the area around the mold inlet port and selective means in the housing for evacuating the mold cavity through the port and for injecting polymer into the port, as well as a fluid jacket for heating or cooling the polymer immediately prior to injection. The injecting means is disclosed as a pneumatically or hydraulically operated injection barrel containing a further pneumatically or hydraulically operated needle valve for controlling flow of polymer through the injection barrel and sealing the barrel during the evacuation step.
