Us Patents

  • High Temperature Nmr Sample Spinner

    view source
  • US Patent:
    52026337, Apr 13, 1993
  • Filed:
    Nov 1, 1990
  • Appl. No.:
    7/607521
  • Inventors:
    F. David Doty - Columbia SC
    Jonathan B. Spitzmesser - Blythewood SC
    David G. Wilson - Winchester MA
  • Assignee:
    Doty Scientific, Inc. - Columbia SC
  • International Classification:
    G01R 3320
  • US Classification:
    324321
  • Abstract:
    A high-strength, thin-wall ceramic cylinder partially closed at one end, with radial-inflow turbine blades ground into the partially closed end thereof, provides the rotational drive, surface protection, and burst strength necessary to contain and spin a low strength, disposable soft ceramic capsule, loaded with a sample for NMR experiments, at high rotational speeds inside an NMR receiver/transmitter coil. An improved radial inflow turbine design results in higher efficiency for micro-turbines. A cylindrical air journal bearing at both ends provides radial stability and support. An axial thrust air bearing is formed at the end opposite the turbine blades between the sacrificial bottom of the soft capsule and a thrust ring. The high-strength ceramic is typically of a partially stabilized zirconia or hot pressed silicon nitride. The disposable capsule is typically of hexagonal boron nitride.
  • Microtube Strip Surface Exchanger

  • US Patent:
    49287559, May 29, 1990
  • Filed:
    May 31, 1988
  • Appl. No.:
    7/200139
  • Inventors:
    Francis D. Doty - Columbia SC
    Jonathan B. Spitzmesser - Columbia SC
  • Assignee:
    Doty Scientific, Inc. - Columbia SC
  • International Classification:
    F28F 312
  • US Classification:
    165168
  • Abstract:
    A microtube-strip module, consisting of a plurality of parallel rows of microtubes, metallurgically bonded to rectangular header tubestrips, is encapsulated in solid metal in such a way as to leave at least one major surface exposed in a manner suitable for metallurgical bonding to an objective surface requiring heat transfer. Fluid connections are provided perpendicular to the objective surface to facilitate parallel manifolding of a plurality of these modules with high surface coverage. The device is intended for ultra high thermal flux applications, especially in aerospace and in controlled thermonuclear fusion, for the efficient transfer of heat between an objective surface and a working fluid, especially high pressure helium gas.
  • Microtube Array Space Radiator

  • US Patent:
    52676056, Dec 7, 1993
  • Filed:
    Sep 6, 1990
  • Appl. No.:
    7/578762
  • Inventors:
    F. David Doty - Columbia SC
    Gregory S. Hosford - Columbia SC
    Jonathan B. Spitzmesser - Columbia SC
  • Assignee:
    Doty Scientific, Inc. - Columbia SC
  • International Classification:
    B64G 150
  • US Classification:
    165 41
  • Abstract:
    The MTS radiator consists of planar arrays of micro-tube strip modules, each of which contain two or three rows of about 200 properly spaced microtubes per row. The three-dimensional tubular titanium structure with support members between microtubes maximizes stiffness and strength per mass. The working fluid--typically hydrogen at 0. 1 to 1 MPa--circulates through the microtubes, and most of the radiation occurs from their walls, which are only 0. 2 to 0. 4 mm thick. This allows specific mass below 1 kg/m. sup. 2. The operating temperature range is typically 200-650 K. The radiator's radiating surface comprises a heavily oxidized, metal alloy with a corrosion resistant, refractory alloy film deposited on it.
