Capillary Liquid Fuel Nuclear Reactor
| United States Patent | Inventor | Appl. No. | Assignee |
|---|---|---|---|
| #4327443 Apr 27, 1982Filed: Jan 17, 1980 | Donald J. Cotton (Washington, DC) | 6/112739 | |
| International Classification: | G21C 344 | U.S. Classification: | 376359 |
Abstract:
Capillary liquid fuel elements, created by the method of confining a liquid fuel in horizontal capillary troughs, are employed to create the core of a nuclear reactor to generate useful heat energy. The reactor incorporates the inherent advantages of a liquid fuel reactor: high specific power, high fuel burnup, inherent safety, ease of control, and simple fuel preparation, processing, reprocessing, and handling. The reactor in addition, has advantages unavailable in other liquid fuel reactors: high breeding potential, low delayed neutron loss, low pumping power requirement, low fission material external holdup, direct fuel-coolant heat exchange capability, and low construction material cost.
Mower And Reel With Axially Offset Chevron Blade Apexes
| United States Patent | Inventor | Appl. No. | Assignee |

| #6318059 Nov 20, 2001Filed: Jan 28, 2000 | Donald F. Cotton (Andalusia, AL) | 9/493973 | Bush Hog, L.L.C. (Selma, AL) |
| International Classification: | A01D 3447 | U.S. Classification: | 56251 |
Abstract:
A foliage mowing apparatus and mowing reel assemblies include a plurality of helically shaped blades which are mounted circumferentially with respect to each other. Each blade has a chevron-type junction or apex lying within a radially extending plain which is transverse to the longitudinal axis of the reel. Apexes of adjacent blades do not lie along the same radial plane. Instead, each apex is axially spaced from each of its adjacent apexes. With this structure, if a piece or blade of grass passes uncut through an apex area, a straight blade section follows immediately in order to cut or trim this piece or blade of grass.
Electromagnetic Shape Calibration Of Tubes
| United States Patent | Inventor | Appl. No. | Assignee |
|---|---|---|---|
| #8099989 Jan 24, 2012Filed: May 4, 2009 | John R. Bradley (Clarkston, MI) Michael H. Lovell (Leonard, MI) Kevin R. Marks (Durand, MI) Terry A. Kent (East China, MI) Donald W Cotton (Royal Oak, MI) | 12/434703 | GM Global Technology Operations LLC (Detroit, MI) |
| International Classification: | B21D 39/00, B23P 17/00 | U.S. Classification: | 72 56, 72 58, 72 61, 72 62, 72430, 294192 |
Abstract:
Articles are often formed from a tubular workpiece in a process which does not usefully shape the ends of the tube. In an embodiment of the invention, tube ends may be mechanically reduced in cross section and then expanded against a secondary forming surface(s) using an electromagnetic force to obtain desired shapes for the tube ends and minimize scrapping of workpiece material.
Reel Assembly For Mower
| United States Patent | Inventor | Appl. No. | Assignee |
|---|---|---|---|
| #5291724 Mar 8, 1994Filed: Feb 14, 1992 | Donald F. Cotton (Andalusia, AL) | 7/837251 | T.I. International, Inc. (Andalusia, AL) |
| International Classification: | A01D 3447 | U.S. Classification: | 56251 |
Abstract:
A mechanism for use in a reel type lawn mower for maintaining a constant uniform pressure between V-shaped reel blades and a bedknife. The blades are arranged to maintain continuous contact with the bedknife on both sides of the center of the reel. A biasing unit acts between the reel unit and the bedknife unit to apply a regulated pressure on both sides of the reel center.
Vertical Liquid Electrode Employed In Electrolytic Cells
| United States Patent | Inventor | Appl. No. | Assignee |
|---|---|---|---|
| #4091829 May 30, 1978Filed: Feb 3, 1977 | Donald J. Cotton (Washington, DC) | 5/765198 | |
| International Classification: | C25B 136 | U.S. Classification: | 137 1 |
Abstract:
A vertical liquid electrode is employed in an electrolytic cell used to manufacture chemical products by the electrolytic decomposition of an electrolyte. The cell incorporates the advantages of high current density, high current efficiency, low space requirement, low liquid electrode requirement, and convenience of optional diaphragm employment.
Reel Assembly For Mower
| United States Patent | Inventor | Appl. No. | Assignee |
|---|---|---|---|
| #5477666 Dec 26, 1995Filed: Aug 20, 1993 | Donald F. Cotton (Andalusia, AL) | 8/109251 | T.I. International, Inc. (Andalusia, AL) |
| International Classification: | A01D 3447 | U.S. Classification: | 56251 |
Abstract:
A mechanism for use in a reel type lawn mower for maintaining a controlled constant uniform pressure between V-shaped reel blades and a bedknife. The blades are arranged to maintain continuous contact with the bedknife on both sides of the center of the reel. A biasing unit acts between the reel unit and the bedknife unit to apply a regulated pressure on both sides of the reel center in response to a feedback signal such as a temperature signal at the reel/bedknife interface.
