Abstract: A connection between a graphite or carbon block having a cavity therein and the end of an electrical conductor disposed therein is made with a tamping material comprising flowable graphite powder, a metal oxide, a resin binder, and a flow promoter such a silica or a resin. The finished connection is treated with an acid dopant which reacts with the metal oxide to form a bond between the conductor and the block.
Abstract: Tantalum anode bodies having a pressed-in nickel coated tantalum riser wire which provides increased bond strength and improved leakage characteristics.
Abstract: Lead oxide-base material for multilayer ceramic capacitors having high dielectric constant and insulation resistance over wide temperature range, e.g., 10.degree. C. to 85.degree. C.
Abstract: A battery of special burners, each adapted for the treatment of a particular range of waste material formed during the conversion of metallurgical grade silicon to high purity silane and silicon, is accompanied by a series arrangement of filters to recover fumed silica by-product and a scrubber to recover muriatic acid as another by-product. All of the wastes are processed, during normal and plant upset waste load conditions, to produce useful by-products in an environmentally acceptable manner rather than waste materials having associated handling and disposal problems.
Abstract: Copper end terminations of excellent electrical and mechanical properties are provided on multielectrode ceramic capacitors by applying copper, glass frit metallizations to the ends of a ceramic capacitor and firing the applied metallization in an atmosphere of nitrogen which contains a controlled partial pressure of oxygen.
Abstract: A device for use in making encapsulated chip electrolytic capacitors of precise dimensions having planar surfaces and anode and cathode terminals formed from a metal channel containing the electrolyte capacitor.
Abstract: A storage container is formed by joining together the sides and top of a pair of matched laminated flat sheets. The bottom portions are joined together adjacent the sides, but the center is sealed along the sealing surfaces of a tube connector assembly, the connector portion being in the form of a parallel pipe head, the center of which is enclosed a tube. The tube extends through the connector and projects outwardly therefrom to provide a closable access path for filling and draining the container. The projected portion of said tube is corrugated.A sleeve is formed along the top edge of the sealed top portion of sealed container and a stiffener rod is installed in the sleeve to provide a more stable structure for handling when the container is filled. Below the sleeve and horizontally centered is a hook mounting aperture for holding the container in the drain position.
Abstract: An invention is described in which a portion of one of the product streams from an adsorption system is used to wash a recycle gas stream in order to improve the quality of one of the products.

Abstract: An improvement to a continuous solvent extraction-steam distillation process for the recovery of aromatic hydrocarbons in the range of C.sub.6 -C.sub.16 from a feed stream containing such aromatics and aliphatic hydrocarbons in the range of C.sub.5 -C.sub.16 which resides in utilizing two heat exchangers wherein the heat of condensation of the overhead stripper vapor and vapor sidedraw products is recovered and utilized to vaporize the stripping water, thereby producing stripping steam which in turn is compressed up to the pressure present at the bottom of the stripper and resulting in the reduction of the heat load of the process.

Abstract: Tri- and dichlorosilanes formed by hydrogenation in the course of the reaction of metallurgical silicon, hydrogen and recycle silicon tetrachloride are employed as feed into a separation column arrangement of sequential separation columns and redistribution reactors which processes the feed into ultrahigh purity silane and recycle silicon tetrachloride. A slip stream is removed from the bottom of two sequential columns and added to the recycle silicon tetrachloride process stream causing impurities in the slip streams to be subjected to reactions in the hydrogenation step whereby waste materials can be formed and readily separated.
Abstract: Adjustable hub mount for circular saw blade which enables the substantial elimination of blade wobble due to non-uniform flatness of the saw blade.
Abstract: Magnetic film-substrate composites of enhanced quality are provided by rotating a garnet substrate immersed in a melt of magnetic film material to obtain a growth of magnetic film having uniaxial anistropy on the substrate normal to the substrate surface and maintaining the immersed substrate stationary in the melt after a desired film growth has been achieved to effect enhancement of the anisotropy constant of the film.
Abstract: Capacitive electrical heating of a fluidized bed enables the individual solid particles within the bed to constitute the hottest portion thereof. This effect is achieved by applying an A. C. voltage potential between dielectric coated electrodes, one of which is advantageously the wall of the fluidized bed rejection zone, sufficient to create electrical currents in said particles so as to dissipate heat therein. In the decomposition of silane or halosilanes in a fluidized bed reaction zone, such heating enhances the desired deposition of silicon product on the surface of the seed particles within the fluidized bed and minimizes undesired coating of silicon on the wall of the reaction zone and the homogeneous formation of fine silicon powder within said zone.
