Abstract: RAPID ELECTRIC-ARC EXTINGUISHING ASSEMBLY    IN CIRCUIT-BREAKING DEVICES SUCH AS      ELECTRIC CIRCUIT BREAKERS   ABSTRACT      A rapid arc extinguishing assembly includes an arc chute comprising a large number of essentially parallel deionizing plates each in form of thin magnetically permeable, electrically conductive plates bent in U-shape, with the curve of the U facing the circuit breaker contacts and the arms thereof insulated from each other by a thin insulation sheet.  To promote arc extinction by the arc chute and accelerated breaker contact separation, the breaker contacts are flanked by a magnetic assembly comprising opposed columns of parallel, spaced ferromagnetic plates embedded in an insulating material.  The columns may be magnetically coupled by a yoke to create a closed slot in which the breaker movable contact travels.

Abstract: PLENUM DRYING HOPPER WITH INTEGRAL HEATERS     Abstract of the Disclosure A plenum drying hopper for granular material includes a housing enclosing a plenum chamber, an upper material inlet for introducing a flow of granular material into the plenum chamber, and a perforate diffuser cone, located in the lower portion of the plenum chamber, that directs the granular mater-ial from the plenum chamber into a material outlet.  The per-forations in the diffuser cone are large enough to permit ready passage of gas therethrough but small enough to preclude passage of all but the finest particles of the granular material.  A gas inlet extends into the lower portion of the housing for intro-ducing a drying gas (air) into the plenum chamber; a gas outlet discharges the gas from the upper part of the housing.  Heaters are provided for heating the gas prior to its entry into the plenum chamber.  The improvement comprises a deflection shield structure mounted in the housing below the plenum chamber between the heaters and the diffuser cone, that directs heated air along a labyrinthine path from the heaters through the diffuser cone and into the plenum chamber.  It also shields the diffuser cone from the heaters to prevent radiant heat from reaching the diffuser cone, and deflects fine particles of the granular material that pass through the diffuser cone directly into the material outlet.

Granted: 1984-01-31
Abstract: Abstract:          A system, method and apparatus for converting solar energy into heat and/or shaft work and employing two working fluids in admixture is described.  One fluid has a relatively low boiling point and is capable of being readily converted to a vapor at low, system pressure.  The other fluid has a re-latively high boiling point and is not capable of being read-ily vaporized at low, system pressure.  The mixture of fluids is passed through a solar energy absorber or collector where the fluids are heated, the lower-boiling fluid undergoing con-version at least in part to the vapor phase and the higher-boiling fluid remaining in the liquid phase.  The heated flu-ids are passed into a disengaging zone where the vapor phase is separated from the liquid phase.  Thereafter, the liquid phase is passed to an energy storage zone and the vapor phase, which consists entirely of the lower-boiling fluid, may be fed to a gas motor to generate useful shaft power   Vapor from the outlet end of the gas motor or direct from the dis-engaging zone also may be passed through a heat exchanger to give up at least a portion of the sensible heat, and possibly also its latent heat, to a heat exchange fluid.  The lower-boiling-point fluid, which may exist in both liquid and vapor phases, is admixed with the higher-boiling, liquid phase fluid from the energy storage one, and then either rein-troduced into the solar collector or by-passed around the solar collector, depending upon the availability of solar insolation.

Abstract: ABSTRACT            Multi-layer magnetic thin-film disks comprising substrates with aluminum and a synthetic resin layer underneath the matallic magnetic layer are subject to the formation of pin holes in the synthetic resin layer, which pin holes are caused by galvano corrosion of the aluminum of the substrate. The pin holes are passivated by aluminum oxide which is advantageously effected by anodically oxidizing the aluminum of the substrate in an electrolytic bath, the electric voltage of the bath being well below the normal passivation voltage for aluminum.

Abstract: ABSTRACT      The invention relates to a method of forming a metal-resin bond in the presence of environmental contamination of the metal surface by, for example, adsorbed water.  The method consists of cleaning the metal surface and then coating it with a pre-treatment material adapted to displace the adsorbed contaminant and to be displaced in turn by the applied resin.  The method is particularly relevant to the formation of steel/epoxy resin bonds underwater for the repair of submerged structures.  The pre-treatment material may consist of a hydrocarbon solvent containing in solution a surfactant such as an ionic surfactant together with a viscous hydrocarbon such as petroleum jelly.

Abstract: ABSTRACT OF THE DISCLOSURE          A method of operating a diesel engine is disclosed.  The method requires the introduction into combustion chambers of the diesel engine of a diesel fuel, air and a catalyst material which lowers the temperature at which soot will be oxidized.  The diesel fuel is burned in the combustion chambers of the diesel engine to form exhaust gases.  These exhaust gases contain soot which is a by-product of the burning of the diesel fuel, and also contain the catalyst material in a highly dispersed oxide form.  The exhaust gases are passed into a trap structure in which the soot is trapped.  The highly dispersed catalyst material is trapped on the soot during any one, any combination, or all of the following: (a) the time the soot is in the combustion chamber, (b) the time the soot is passing from the combustion chambers of the diesel engine to the trap structure, (c) while the soot is trapped in the trap structure.  Periodically, the temperature within the trap structure is raised to a temperature which is sufficient to permit catalytic oxidation of some or all of the soot trapped in the trap structure.  This temperature of catalytic oxidation is lower than the temperature at which the soot would oxidize if no catalyst material was present.
