US Patent:

6493638, Dec 10, 2002

Filed:

Mar 1, 2000

Appl. No.:

09/516490

Inventors:

Robert A. McLean - Brea CA
James A. Wurzbach - San Diego CA
Harold C. Gilbert - North Kingston RI
Lawrence A. Schatzmann - Yorba Linda CA
Gregory E. Smith - Fullerton CA
Thomas B. Stanford - Port Hueneme CA

Assignee:

Raytheon Company - Lexington MA

International Classification:

G01N 3100

US Classification:

702 22, 702 24

Abstract:

An apparatus for measuring volatile organic compounds in a gas includes a sensor chamber having a housing with a gas inlet, a gas outlet, and a gas flow path from the gas inlet to the gas outlet, a set of baffles within the housing and positioned in the gas flow path, and a set of sensors within the housing and positioned in the gas flow path. Each sensor has an electrically conductive polymer whose electrical properties are dependent upon the presence of specific volatile organic compounds in the gas flow. Desirably, the set of baffles and the set of sensors are cooperatively positioned such that the time for gas to flow from the gas inlet to each of the sensors is substantially the same. The apparatus further includes a pump that removes the gas from the gas outlet of the housing, and an electronic circuit that measures the electrical properties of each of the sensors.

International Classification:

A63C001/16

US Classification:

280 1118, 280 1117, 280 113, 280 11223

Abstract:

An ice skate chassis is configured so that a user can adjust the pitch of the skate chassis between a plurality of discrete pitch positions. The pitch is adjusted by locking the ice blade at a desired angle relative to a bladeholder of the chassis. The blade can be positively locked at a plurality of discrete, repeatable angle positions so that the angle will not slip or creep during skating.
