  • Peak power generation
    Patent number: 4275310
    Abstract: Electric power is provided during periods of peak demand, employing a turbine generator facility activated by the expansion of compressed air, withdrawn from an underground air storage reservoir, in a substantially isothermal system. A generator system, which may comprise a steam boiler or a fuel gasifier, is employed for isothermal compression of air into reservoir storage during periods of low power demand.

  • Weather resistant composites
    Patent number: 4100325
    Abstract: Improved weather resistant products such as building siding, shutters, roof vents and the like, are made by coextruding or laminating a plasticized vinyl chloride capstock with a substrate of rigid vinyl chloride polymers, chlorinated vinyl chloride polymers, or acrylonitrile-butadiene-styrene polymers. The resulting composites are much improved over rigid PVC, chlorinated PVC, or ABS articles alone for retention of appearance and retention of impact on aging.

  • Method of extracting gallium
    Patent number: 3932230
    Abstract: A method of removing gallium from tin, lead or tin-lead alloy in which the molten metal containing gallium is treated with a molten flux of alkali metal hydroxide, alkali metal carbonate or a mixture of such constituents where the alkali metal is lithium, sodium, potassium or a mixture of these. Preferably the metal and flux are stirred together, then separated, and the flux dissolved in water and gallium recovered from the solution by electrolysis.
