Barry E. Newton 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).

  • Combination valve and regulator with vented seat for use with pressurized gas cylinders, particularly oxygen cylinders
    Patent number: 7234680
    Abstract: A combined valve-regulator apparatus, for safely regulating the flow of combustible gases such as oxygen. A compressible o-ring is used to provide controllable sealed seating of the valve and regulator during operation. A system is provided in the valve-regulator apparatus for venting the o-ring seat elements, to minimize undesirable ballooning or extrusion otherwise resulting from dynamic pressures and changing forces due to rapid gas flows through the regulator.

  • Cylinder valve and bayonet check-filter with excess-flow protection feature
    Patent number: 6607007
    Abstract: A valve apparatus especially well-suited for use in gaseous oxygen delivery systems. A valve apparatus is provided that substantially reduces the risk of fire in high-pressure oxygen systems. The apparatus is particularly well-suited for use as a plug valve on ordinary cylinder containers, but may be beneficially used in any pressurized gas system, particularly oxygen systems such as those encountered in many industrial facilities. The wetted portion of the valve is isolated from threaded portions to prevent particulate contamination of the gas stream. The valve seat is located to protect it from direct impact of high-velocity gas streams. The inventive valve, and its associated inventive check-filter and excess-flow prevention features, reduces the potential for hazardous combustion at valve points within oxygen delivery systems.
