US Patent:

47262320, Feb 23, 1988

Filed:

Jun 2, 1986

Appl. No.:

6/869744

Inventors:

Donald J. Koneval - Brookfield WI

Assignee:

Gould Inc. - Rolling Meadows IL

International Classification:

G01L 708
G01L 906
G01L 1904

US Classification:

73708

Abstract:

A pressure transducer, which includes a silicon diaphragm with ion-implanted resistors in Wheatstone Bridge configuration and in insulating layer covering the diaphragm, is provided with temperature compensation for differences in thermal expansion coefficients of the layers by depositing a layer of aluminum onto the central portion of the diaphragm.

Filed:

Nov 16, 1988

Appl. No.:

7/271812

Inventors:

Donald J. Koneval - Brookfield WI
Harold J. Pollnow - Dousman WI
Richard J. Molus - Greenfield WI

Assignee:

Allen-Bradley Company, Inc. - Milwaukee WI

International Classification:

G01D 1124
G01D 1100

US Classification:

73431

Abstract:

An enclosure for a transducer includes a cylindrical housing and an end cap covering one end of the housing. A coupling ring engages an annular projection on the one end of the housing and a threaded portion of the end cap to hold the two elements in an abutting relationship. The housing has a threaded aperture therethrough. One of a series of different types of plumbing fittings, each having a common threaded projection, has the threaded projection received in the aperture of the housing. The end cap has a threaded aperture therethrough with one of a series of different types of electrical couplings received therein. Each of the couplings of the series has a common threaded projection which is adapted to mate with the end cap aperture. A set of stops is provided to prevent the end cap and the housing from rotating more than 360 degrees with respect to each other.

Assignee:

Gould Inc. - Rolling Meadows IL

International Classification:

G01D 1518

US Classification:

346140A

Abstract:

An impulse ink jet mounted in an ink reservoir so as to be a self-contained writing device for X-Y and strip chart process recorders and table top graphic recorders, with the jet being associated with a length of energy absorbing conduit coiled within the reservoir so as to minimize the effects of acceleration on the ink; the conduit allowing the ink jet to achieve a flat response to the driving pulse rate through its full response range.

Filed:

Oct 22, 1979

Appl. No.:

6/086642

Inventors:

Donald J. Koneval - Arlington Heights IL

Assignee:

Gould Inc. - Rolling Meadows IL

International Classification:

G01B 720

US Classification:

73766

Abstract:

A thin film strain gage transducer includes temperature compensation resistances on an unstrained portion of the flexure element of the transducer. The compensation resistances are formed of the same material as the electrical leads interconnecting the strain gage resistances and also are deposited simultaneously with the electrical leads during manufacture.
