US Patent:

44133316, Nov 1, 1983

Filed:

Apr 26, 1976

Appl. No.:

5/680254

Inventors:

Linwood M. Rowe - Glen Burnie MD
Dale D. Skinner - Severna Park MD
John H. Thompson - Severna Park MD

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H04B 1300

US Classification:

367151

Abstract:

A transducer made up of a plurality of piezoceramic tubes arranged in end to end relationship with elastomeric material between tubes. The tubes are poled and driven axially; however, the hoop mode of operation is utilized to obtain a fan-shaped beam extremely narrow in one direction and extremely broad in the direction perpendicular thereto. A suitable backing arrangement is provided for the transducer when mounted on a support body to prevent degradation of the beam pattern.

Appl. No.:

6/812048

Inventors:

Dale D. Skinner - Severna Park MD

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H04R 1700

US Classification:

367159

Abstract:

A cylindrical transducer for use as a low frequency hydrophone and having inner and outer electrodes at least one of which is deposited in a certain predetermined pattern having smooth continuous lines whereby the electrode coverage varies as a function of transducer axial length.

Appl. No.:

5/791434

Arthur Nelkin - Annapolis MD
Dale D. Skinner - Severna Park MD
Donald G. Wilson - Severna Park MD
Harold D. Palmer - Severna Park MD

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H01L 4110

US Classification:

310334

Abstract:

A sand transport detector which detects the discrete impingements of sand particles on an elongated probe member inserted into the sand. A piezoelectric transducer element is cemented to the probe and produces an output signal when impingement occurs. With an electronic circuit coupled to the transducer, an indication of sand transport may be obtained.

Filed:

Jan 2, 1990

Appl. No.:

7/459861

Inventors:

Dale D. Skinner - Severna Park MD
John H. Thompson - Severna Park MD

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H04B 1700

US Classification:

367 13

Abstract:

A single test transducer or a line array of test transducers is placed above the transducers of an array under test and provided with a simulated flow noise signal. The response of all of the transducers under test is derived and stored whereupon the test transducer or line array of test transducers is moved to a subsequent position wherein the process is repeated. After all positions are indexed, the stored signals representing the outputs of all of the transducers of the array under test for all transmissions are combined and processed to derive a transducer array output signal for analysis purposes.
