Patents by Inventor James W. Langeliers

James W. Langeliers has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Heat and mass transfer apparatus and method for solid-vapor sorption systems
    Patent number: 6736194
    Abstract: A sorber heat exchanger is provided with a substrate material incorporating a sorbent for reacting with a polar gas refrigerant or hydrogen. A preferred sorbent is a metal salt capable of reacting with the polar gas refrigerant to form a complex compound. The sorbent incorporating substrate is loaded into the reactor space between the heat transfer surfaces. Incorporating the sorbent into the substrate reduces sorbent migration thereby improving performance and life expectancy of the heat exchanger.
    Type: Grant
    Filed: December 7, 2000
    Date of Patent: May 18, 2004
    Assignee: Rocky Research
    Inventors: Uwe Rockenfeller, Lance D. Kirol, Kaveh Khalili, James W. Langeliers, William T. Dooley

  • Pulsed operation control valve
    Patent number: 5675982
    Abstract: A valve assembly includes a refrigerant inlet port and a refrigerant outlet port having a restricted opening, with the inlet port opening at least 2 times larger than the restricted outlet port opening. The valve includes components for opening and closing the inlet port in response to valve cavity pressure between the inlet and outlet ports.The larger inlet port relative to the restricted outlet port provides for rapid pressure buildup in the valve cavity when the inlet port is open which, in turn, causes rapid closing of the inlet port. The valve is capable of rapid cycling rates, highly effective for small refrigeration or cooling apparatus, as well as for controlling pressure in other applications requiring pressure regulation.
