US Patent:

20090126793, May 21, 2009

Filed:

Nov 20, 2007

Appl. No.:

11/986261

Inventors:

Martin William Collins - Staten Island NY, US

International Classification:

H01L 31/04

US Classification:

136259

Abstract:

A multi-layered transparent photovoltaic cell of the silicon variety. With transparent electrodes on both sides of each of the two independent silicon structures. The spectral makeup of the captured light is influenced by designing/controlling the optical characteristics of the layers of the two photovoltaic layers, and their non-conductive components. Light passing thru the collector that is not captured for photovoltaic purposes is available to provide illumination to the interior of an office, dwelling, or vehicle.

Filed:

Aug 27, 1973

Appl. No.:

5/391862

Inventors:

Martin F. Collins - Somerset NJ
Romuald Michalek - Hackensack NJ

Assignee:

Engelhard Minerals & Chemicals Corp. - Iselin NJ

International Classification:

B01D 5334

US Classification:

423248

Abstract:

Tritiated species, e. g. , tritium, tritiated water, and/or tritiated hydrocarbons, are removed from gas streams comprised thereof by reacting the same over a precious metal catalyst with sufficient air or oxygen to insure conversion of all tritiated species to tritiated water and, if hydrocarbons are present in the gaseous feedstock, carbon dioxide. The tritiated water and any other moisture that might be present in the reaction effluent are next adsorbed by a desiccant dryer, preferably to a level of less than one part per million. Most desirably, the desiccant dryer effluent is then diluted with non-radioactive water such that the tritiated water is diluted by a factor of at least about 1,000 to 1; the resulting water mixture can be adsorbed from the diluted effluent by a second dessicant dryer to provide a value in the ultimate effluent gas of less than about one-half parts per billion tritiated water.
