  • Patent number: 4945840
    Abstract: This invention is directed to an apparatus for the combustion of coal comprising a heated tubular reactor having combined air and granular coal inlet means for tangentially introducing air and granular coal into the reactor, external heating means, insulation means, and an outlet means wherein the coal is partially burned in the heated tubular reactor to a temperature 50 to 100 degrees Fahrenheit below the fusion temperature of the ash produced from the coal to be used to produce partial combustion products composed of coke, ash and combustion gases. The partially combusted products exiting from the tubular reactor are tangentially introduced with additional air into a second tubular reactor where they are completely burned.

  • Patent number: 4866799
    Abstract: A fire retardant mattress comprising a central coiled spring support assembly, a first layer of polyurethane foam and/or matting covering on the top and bottom of said support assembly, a second layer of a fire resistant resilient material preferably polychloroprene foam covering the surface of said first top and bottom layers and a fire shield composed preferably of a woven fiber glass material attached to the edge of the perimeter of said second top and bottom layers to completely encapsulate the support assembly and first layers in a fire retardant capsule; said fire shield having sufficient slack to allow the springs of the mattress to expand due to the effect of heat and fire and thus preventing the rupturing of the integrity of the mattress and exposure of the polyurethane foam and matting to flames by said expanding springs and thereby preventing the inner contents of the mattress from coming in contact with fire and/or burning with a concommitant sudden release of heat and smoke.

  • Patent number: 4845635
    Abstract: A system and method are disclosed for automatically stamping designs onto candles under computer control. For a given stamped mark, a turret selects the tool with a specific die is to be stamped. The turret orients the tool angle about the axis defined by the tool's travel line during stamping by use of a planetary gear system. A rotatable chuck mounted on a movable bed selects the location on the candle surface to receive the die. A linear solenoid plunges the selected and oriented tool onto the candle. This process is repeated until all marks in a desired design are completed. The planetary gear system is designed so that all tool orientations are controlled by one motor, and tool anti-rotation during travel is controlled by the face length of a sun gear.

  • Patent number: 4603497
    Abstract: A platform having two clamps for securing the barrels of two pistols substantially parallel permitting the operator of the two pistols, using both hands, to hold said pistols by their hand grips and to aim and fire the pistols at the same target simultaneously and/or successively, whereby stability of the two aimed pistols is imparted during repeated firing.

  • Patent number: 4389391
    Abstract: An improved method of beneficiating ilmenite using two chlorinators in order to oxidize by-product iron chlorides to chlorine in the vapor phase and eliminate the necessity of separating the chlorine from combustion gas by cryogenic methods comprising using a first stage which produces beneficiated ore, and, inter alia, carbon dioxide, iron chlorides, predominantly ferrous chloride, which are condensed to gain the separation from CO.sub.2 ; solid iron chlorides are fed to an oxidation zone in the void above the second stage beneficiator and reacted with oxygen; heat required for vaporization of the condensed chlorides is supplied in part by beneficiation within the second stage. The fluidized bed overflow of the second stage beneficiator is magnetically separated to separate practically pure T.sub.1 O.sub.2, useful as a starting material for T.sub.1 O.sub.2 pigment and a recycle stream of magnetic partially beneficiated ore.

  • Patent number: 4353740
    Abstract: A process for treating a particulated gold bearing ore to recover the gold therein is disclosed. The process includes roasting the ore to remove sulfides as sulfur dioxide followed by chlorination of the ore at a temperature of about C. in the presence of iron to form a mixture of volatile gold chlorides and volatile gold-iron chlorides in the chlorine off gases followed by condensing the gold compounds by passing the mixture through a salt such as sodium chloride to form a salt melt and separating the gold from the melt.

  • Patent number: 4211755
    Abstract: A process for beneficiating titaniferous ores to a product having a lower percentage content of silicates, and other inerts comprising, at temperatures of C., passing chlorine through a bed comprising (a) a first fraction of particulate titaniferous ore having about 90% of large particles, (b) a second fraction having about 90% small particles and (c) carbon in an amount equal to 10-30%, by weight, of the total titaniferous ore present, and removing freed silicates and inerts and by-product iron chloride thereby consuming (b) with the titanium dioxide values present in (b) being substituted for iron oxide values present in (a). The beneficiated ore is useful as an intermediate for preparing titanium dioxide pigments.

  • Patent number: 4189797
    Abstract: A firm, shape-retaining mattress made of layers of resilient material separated by a layer of nonwoven material such as jute, which are held in relation to one another by a strong, nonwoven fabric material intertwined among the layers and through slits in the layers in a manner to substantially prevent movement relative to one another.
