Assignee:

ExxonMobil Research and Engineering Company - Annandale NJ

International Classification:

B01D053/60

US Classification:

423/235000

Abstract:

A process for reducing NOconcentrations in waste gas streams by contacting the waste gas stream with a reducing agent selected from ammonia and urea and then oxidizing the lower NO's present in the waste gas streams to higher oxides with sodium chlorite.

Filed:

Oct 7, 1974

Appl. No.:

5/512621

Inventors:

William L. McLaughlin - Washington DC
Harry Levine - Silver Spring MD
Marvin Rosenstein - Rockville MD

Assignee:

The United States of America as represented by the Secretary of the
Department of Health, Education and Welfare - Washington DC

International Classification:

G03C 152

US Classification:

96 90R

Abstract:

A hard, clear, glassy, smooth polymer with a dry surface having a dye precursor therein which forms a permanent color at those areas of the solid polymer that have been irradiated with ultra-violet or ionizing radiation is formed by combining vinyl and/or acrylic monomers, a triphenylmethane cyanide dye precursor and a chemical initiator that is compatible with the dye cyanide and polymerizing in the presence of a slight excess of hydrogen ions in an inert atmosphere.

International Classification:

G01T 102

US Classification:

2504741

Abstract:

A radiation dosimeter includes an optical waveguide enclosing a radiation-sensitive material that changes color or color intensity with increasing amounts of exposure to high energy ionizing radiation. A light-transparent radiation-transparent light-transmitting member extends along the length of the optical waveguide, and is separated from the radiation-sensitive material by a light-opaque sidewall. Outside the light-transmitting member is a light-opaque shield that permits light to enter distal ends of the waveguide and the light-transmitting member, while permitting light to exit the proximal ends thereof, the light-opaque shield being transparent to high energy ionizing radiation. A light transmission comparator is positioned adjacent the proximal end of the light-transmitting member, the comparator including a plurality of transparent segments of different color or color intensity arranged in an array of consecutive light-to-dark shades, the color or color intensity of each segment being an exact reproduction of an actual dose level coloration that results from exposure of the radiation-sensitive material within the waveguide of a particular dose of radiation, so as to provide for accurate determination of radiation exposure to the optical waveguide under a variety of ambient lighting conditions.
