George R. Gibbs 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).

  • Compact mercury-free fluorescent lamp
    Patent number: 4647821
    Abstract: A compact fluorescent lamp has an outer envelope in which there is supported a capsule containing a mercury-free fill comprised of aluminum tribromide. The fill is energized to produce a plasma discharge which emits ultraviolet and visible radiation. Phosphor, in the form of a particulate layer or a gas, converts the ultraviolet into visible light. The lamp may contain electrodes or be electrodeless. In the electrodeless embodiment RF energy may be capacitively or inductively coupled to the fill.
    Type: Grant
    Filed: September 4, 1984
    Date of Patent: March 3, 1987
    Assignee: GTE Laboratories Incorporated
    Inventors: Walter P. Lapatovich, George R. Gibbs, Joseph M. Proud
  • Mercury-free discharge lamp
    Patent number: 4636692
    Abstract: An ultraviolet light source includes a volume filled with a dose of AlBr.sub.3 and an inert gas. No mercury is used. During electrical discharge excited states of AlBr.sub.2, and AlBr emit light, with AlBr having a broad ultraviolet emission peaking at about 278 nm. The source may be energized with or without internal electrodes. Phosphors may be employed to convert the ultraviolet to visible light. The lamp's envelope may be aluminosilicate coated quartz.
    Type: Grant

  • Compact mercury-free fluorescent lamp
    Patent number: 4480213
    Abstract: A compact fluorescent lamp has an outer envelope in which there is supported a capsule containing a mercury-free fill comprised of aluminum trichloride. The fill is energized to produce a plasma discharge which emits ultraviolet and visible radiation. Phosphor, in the form of a particulate layer or a gas, converts the ultraviolet into visible light. The lamp may contain electrodes or be electrodeless. In the electrodeless embodiment RF energy may be capacitively or inductively coupled to the fill.
