  • Method for making alkylhalosilanes
    Patent number: 4500724
    Abstract: A method is provided for making alkylhalosilanes by effecting reaction between an alkyl halide, such as methyl chloride and powdered silicon in the presence of a copper-zinc-tin catalyst. Significant improvements in reaction rate and product selectivity are achieved when copper is employed at a critical weight percent relative to silicon and critical weight ratios of tin and zinc are employed relative to copper.
    Type: Grant
    Filed: July 28, 1983
    Date of Patent: February 19, 1985
    Assignee: General Electric Company
    Inventors: William J. Ward, III, Alan Ritzer, Kenneth M. Carroll, John W. Flock

  • Phenol recovery from bisphenol-A waste streams
    Patent number: 4351966
    Abstract: Bisphenol-A waste stream derived from the reaction of phenol and acetone in the presence of an acidic condensing agent can be treated with a molecular sieve to obtain good yields of phenol present in the effluent stream either in isolated form or as part of the compounds present in the waste stream.

  • Vapor compression cycle device with multi-component working fluid mixture and improved condensing heat exchanger
    Patent number: 4218890
    Abstract: A vapor compression cycle device is described which includes a multi-component working fluid mixture, and an improved condensing heat exchanger. The vapor compression cycle device includes also a high-pressure liquid accumulator with an associated flow restricting device positioned between the condensing heat exchanger and the evaporating heat exchanger, and a liquid accumulator positioned between the evaporating heat exchanger and the compressor. A method is also described of modulating the capacity of such a device.

  • Vapor compression cycle device with multi-component working fluid mixture and method of modulating its capacity
    Patent number: 4217760
    Abstract: A vapor compression cycle device is described which includes a multi-component working fluid mixture, a high-pressure liquid accumulator with an associated flow restricting device positioned between the condensing heat exchanger and the evaporating heat exchanger, and a low-pressure liquid accumulator positioned between the evaporating heat exchanger and the compressor. A method is also described of modulating the capacity of such a device.
