US Patent:

50501844, Sep 17, 1991

Filed:

Feb 23, 1990

Appl. No.:

7/485250

Inventors:

George A. Nelson - Sandy UT

International Classification:

H01S 308

US Classification:

372107

Abstract:

A laser employing a dispenser cathode is provided with a tubular enclosure surrounding that cathode. The tubular enclosure serves as a support for the bore and the optical chamber on either side of the dispenser cathode and is insulated from ambient temperature conditions by a ballast reservoir housed in a jacket encircling the tubular enclosure. The jacket has peripheral sidewalls spaced apart from the tubular enclosure. Lateral end walls connect the opposite extremities of the peripheral sidewalls in a sealing engagement to the exterior of the tubular enclosure. Communication between the interior of the jacket and the interior of the tubular support is afforded through an aperture formed in the tubular support at a location remote from the dispenser cathode. Leads for the dispenser cathode are disposed in a sealing engagement through the end walls of the jacket and enter the interior of the tubular support through the aperture formed therethrough. By retaining rather than dissipating from the tubular support the heat generated by the dispenser cathode, a predictable and circumferentially uniform amount of longitudinal, temperature-related dimensional changes are induced in the tubular support, preventing cathode housing bending of the support structure between the optical chamber and the bore.

US Patent:

43046614, Dec 8, 1981

Filed:

Mar 10, 1980

Appl. No.:

6/128737

Inventors:

George S. Nelson - Salt Lake City UT

International Classification:

B07B 900

US Classification:

209 35

Abstract:

The present invention discloses a novel machine that, by a dry process, will segregate granules of different specific gravities. The machine first segregates the granules as to size, regardless of their specific gravities and regardless of the multiplicity of the sizes (within limits set by the machine). In the next step the machine feeds individual granules side by side ranging progressively from fine to more coarse into a stream of air that ranges in carrying power from low to high in a sequence corresponding to the increasing sizes of the granules that fall through it. The carrying power of the air stream is regulated to convey granules having the same specific gravity to the same container, regardless of the sizes of the granules. Granules of different specific gravities will be deposited in different containers. Thus gold will be segregated from silver, and silver from copper etc.

Abstract:

An improved optical delivery assembly for an argon-ion or similar medical laser attaches to a wobble plate for thermal tracking and supports in a single integral subassembly an adjustable focusing lens, a beam splitter and associated light detector enabling selective display of power at both proximal and distal ends of the fiber, scattering and blocking shutters, a scattering shutter position sensor, shutter control solenoids, an optical plug position sensor and an optical plug mounting block adapted to interchangeably receive any of several types of optical fiber connecting plugs.
