Patents by Inventor Ralph A. Langensiepen

Ralph A. Langensiepen 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).

  • Publication number: 20090272150
    Abstract: A cradle for a high-temperature fluid delivery system, comprising a shell including a base and two side walls defining a trough, wherein the shell comprises fused zirconia. Fused zirconia provides the high temperature creep-resistance, corrosion resistance and thermal insulation to supported delivery system. The cradle extends system life, increases product quality and reduces costs associated with failure of glass delivery system.

  • Publication number: 20080049431
    Abstract: A technique for reducing the appearance of Newton's Rings for a light emitting device is disclosed. The light emitting device comprises an anti-reflective coating on the inner surface of a cover substrate. A method of making a light emitting device is disclosed, together with a method for reducing the formation of Newton's Rings in a device.

  • Publication number: 20070108900
    Abstract: A technique for reducing the appearance of Newton's rings for a light emitting device is disclosed. The light emitting device comprises a scattering layer positioned contiguous with the inner surface of a cover substrate. Scattering the light reduces or eliminates the opportunity for constructive interference and as a result reduces or eliminates Newton's ring formation.

  • Patent number: 5553657
    Abstract: The present invention relates to the use of a gating means in combination with a spontaneous infiltration process to produce a metal matrix composite body. Particularly, a permeable mass of filler material or a preform is spontaneously infiltrated by molten matrix metal to form a metal matrix composite body. A gating means is provided which controls or limits the areal contact between molten matrix metal and the filler material or preform. The use of a gating means provides for control of the amount of matrix metal which can contact the preform or filler material, which may result in less machining of a formed metal matrix composite body compared with a similar metal matrix composite body made without a gating mean. Moreover, the use of a gating means ameliorates the tendency of a formed metal matrix composite body to warp due to the contact between the formed composite body and matrix metal carcass.
