US Patent:

55850863, Dec 17, 1996

Filed:

Sep 6, 1994

Appl. No.:

8/300898

Inventors:

Edward D. McCullough - Riverside CA
Robert D. Waldron - Hacienda Heights CA

Assignee:

Rockwell International Corporation - Seal Beach CA

International Classification:

B01F 100

US Classification:

4236585

Abstract:

The present invention is a method for enhancing reaction rates when digesting chemical systems which form passivating layers. Particles are introduced into a digestion fluid bath. Digestion is allowed to proceed until passivating layers of digestion products have partially formed on the particles. The layers constitute a diffusion barrier to the digestion fluid and reduce the digestion rate. The particles are periodically conveyed through an ultrasonic beam to remove portions of the passivating layers. Thus, fresh surfaces of the particles are exposed to the digestion fluid bath. The periodic conveyance is such that a desired rate of digestion is obtained.

International Classification:

G02B 522

F24J 208

US Classification:

350 11

Abstract:

Such system can include, in the first plane, a first optical device for producing converging radiation from incident, substantially parallel radiation passing through the first optical device and, in a second plane, substantially parallel to the first plane, a second optical device for receiving, as incident radiation, converging radiation from the first optical device and for recollimating or reducing the degree of convergence of this incident, converging radiation as it passes through the second optical device.

Appl. No.:

7/334685

Inventors:

Robert D. Waldron - Hacienda Heights CA

International Classification:

G02B 504

US Classification:

350286

Abstract:

Systems for deviating and (optionally) converging radiation include two optical devices preferably in parallel planes with one device producing convergence, and the other divergence. Alternatively, the deviating effect can be produced by an array of pairs of dove prisms with the tips of the prisms in each pair either joined to one another or separated by dielectric of lower refractive index, and with the adjacent contiguous pairs joined periodically at the base of each prism along the contiguous surfaces or separated from one another by dielectric.

Appl. No.:

7/767438

Inventors:

Robert D. Waldron - Hacienda Heights CA

Assignee:

International Classification:

C25C 700

US Classification:

204 111

Abstract:

The system includes at least one electrolysis cell having a principal direction of current flow. The electrolysis cell has two electrode surfaces whose mean surface planes are substantially parallel, separated by a fluid electrolyte layer. Separate electric current conducting means, energized by an electric power source and independent of the electrolysis circuit elements are so arranged and constructed with respect to the cell to increase the average component of the magnetic field substantially parallel to the mean electrode surfaces within the fluid electrolyte layer. This increase in the magnetic field is relative to the magnetic field due solely to the electrolysis current. A flow return conduit is included for connecting at least one entrance port of the electrolysis cell to a least one exit port of the electrolysis cell. The ports are disposed substantially parallel to the pressure gradient formed by the magnetic forces present during operation.
