US Patent:

42597323, Mar 31, 1981

Filed:

Jun 4, 1979

Appl. No.:

6/045452

Inventors:

Phillip R. Anderson - Columbia MD
George R. Douglas - Arnold MD
John H. Thompson - Severna Park MD

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H04R 2900

US Classification:

367 13

Abstract:

An acoustic homing torpedo having an array of transducers wherein each transducer has a head mass, tail mass, and a main active element therebetween. An auxiliary active element is placed on the tail mass so that when given a predetermined signal it will cause the main element to provide a corresponding output signal so as to simulate the reception of an actual acoustic wave. By energizing the main element, the response of the auxiliary element may be examined for testing the transducer and the array in a transmit mode of operation.

Assignee:

Hoppmann Corporation - Chantilly VA

International Classification:

B65B 4724

US Classification:

198380

Abstract:

An apparatus and method is provided for producing an oriented single file of articles comprising a conveyor having pockets for receiving articles, a lateral support surface forming a drop zone between it and an edge of the conveyor, a device for determining the direction in which articles are lying within the pockets, and a device for moving articles lying in one direction out of the pocket and onto the support surface. The pockets may be relatively quickly and easily changed to accommodate articles having different widths.

Appl. No.:

5/461334

Inventors:

Phillip R. Anderson - Ellicott City MD

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H04R 2300

US Classification:

367153

Abstract:

An acoustic array of special utility in deep operating antisubmarine torpedoes comprises a plurality of individual transducer elements supported by a back-plate member. An acoustic window made of an elastomeric or plastic material is mounted against the front faces of the transducer elements and forms part of the water-proof housing of the torpedo. The backplate provides abuttive support to the transducer elements against crush pressure exerted by ambient water against the acoustic window. Inserts, made of an acoustic decoupling material which exhibits high crush strength characteristics, are interposed between each transducer element and the backplate. The backplate is made of body sections having interposed therebetween very thin layers of a compliant material, with the layers bondingly confined between the body sections. The compliant material is chosen to be of a type which damps acoustic vibrations which may be present in the backplate by the mechanism of "coulomb friction damping".

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

G01S 966

US Classification:

340 3R

Abstract:

1. A channel defining system for aiding the navigation through a body of er of a vessel equipped with a high resolution pulsed catacoustic system adapted to scan the bottom in range abeam of the vessel comprising An elongated buoyant ridge-like strip of acoustic reflecting material extending lengthwise of the channel on the channel bottom and laterally spaced from the center line of the channel by a substantially constant known distance, and Anchoring weights secured to said strip at spaced positions along its length.
