Filed:

Dec 22, 2003

Appl. No.:

10/745362

Inventors:

Robert Louis Walter - Castro Valley CA, US

International Classification:

B60Q 1/56

US Classification:

362497, 362330, 362603, 362612, 40205, 40546

Abstract:

A license plate system for motorcycle, car, truck or boat including a row of lights supported along an edge of a clear plastic channel so that light from the row enters the interior of the pane through an edge surface of the panel. The front surface of the panel has an area that is textured to form the alpha-numeric characters of the license. The panel is sufficiently thin ( 1/8 to inches) so that Light from the row of lights is confined between the front and rear surfaces of the panel except an area of the front surface that is textured. Therefore the contrast between the illumination of the textured area compared to the smooth area is very pronounced.

Appl. No.:

6/194549

Inventors:

Robert J. Walter - Thousand Oaks CA
Kam C. Wong - Canoga Park CA

International Classification:

C25D 102

US Classification:

204 9

Abstract:

A process for fabricating character bands 22 for computer printers and the product generated thereby. The process comprises the steps of electrodepositing a binary or ternary nickel alloy onto a cylindrical cathodic mandrel 20, preferably machining away excess backing material 36 so as to leave a smooth surface 38, and separating character band 22 from mandrel 20.

International Classification:

B23P 1526

US Classification:

29890054

Abstract:

A method for the manufacture of articles such as heat exchangers, heat absorbers, thermal skins, rocket engine components and the like which method comprises providing a substrate or mold, etching or cutting cooling channels therein, filling said channels and processing to form a part which is then fabricated into the final article. In the production method a unique filler or core material comprising a strontium composition is utilized thus rendering a product of high quality and net-shape finish.

Appl. No.:

6/419273

Inventors:

Robert J. Walter - Thousand Oaks CA
Harold E. Marker - Northridge CA

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

C22C 1907

US Classification:

148425

Abstract:

There are provided superplastic alloys formed by electrodeposition of the alloy onto a cathode from an electrolyte containing a first metal ion, which is iron, nickel or cobalt, and a second constituent different from the first, which is iron, nickel, cobalt, tungsten or molybdenum, or a colloidal dispersoid. The products formed are fine-grain deposits free of intergranular embrittling films, and exhibit grain boundary flow at a superplastic temperature below a recrystallization temperature of the deposit. Nickel-cobalt alloys are preferred, and are deposited from halide-free sulfamate baths, with care being taken to eliminate all anode oxides from the system. In a complex structure, the approximate initial hardware contour is formed by electrodeposition, and the final structure formed by superplastic forming.

Inventors:

Robert J. Walter - Thousand Oaks CA

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

B22F 300

US Classification:

428570

Abstract:

Metal matrix composite materials are formed from a reinforcing, submicron-particle material, such as SiC, which is not easily wettable by a matrix metal, such as Al, and therefore cannot be uniformly dispersed in the matrix because the particles agglomerate. A coating 12 of material, such as Si, easily wettable by the matrix metal, is placed on the surface of the particles 10 before mixing the reinforcing particles in the matrix metal.

International Classification:

B23K 1500

US Classification:

219121EM

Abstract:

A method for healing surface cracks 10, especially in metals, by scanning a high-energy, diffused, pulsed electron-beam past a crack 10 in a slowly moving specimen object 12. The crack 10 moves laterally with respect to the beam so that the beam pattern 14 is a sawtooth pattern comprising a series of overlapping circles 22, each comprising one pulse of diffused energy.

US Classification:

366127

Abstract:

A process of preparing ceramic powders for sintering comprises the steps of dispersing ceramic powders and sintering aids in a low-boiling dispersing liquid to form a suspension, ultrasonically vibrating the suspension to defloculate agglomerates which may have formed, and continuing the ultrasonic vibration until the dispersing liquid is evaporated.
