Bowed Elastomeric Window

US Patent:

4300219, Nov 10, 1981

Filed:

Apr 26, 1979

Appl. No.:

6/033649

Inventors:

Arthur B. Joyal - Bristol RI

Assignee:

Raytheon Company - Lexington MA

International Classification:

H04R 1700

US Classification:

367174

Abstract:

A window for a sonar transducer housing is formed of an elastomeric plate which is bonded to a mounting ring for securing the window to the housing. The plate is bowed with a convex shape during the molding and the curing of the elastomer. During assembly of the housing, the convex surface of the plate faces inwardly and is depressed to a substantially planar configuration by the pressure of oil within the housing. The compression of the elastomer against the mounting ring inhibits separation of the elastomer from the ring.

Sonar Transducer Joint Seal

US Patent:

4949319, Aug 14, 1990

Filed:

Dec 20, 1988

Appl. No.:

7/286688

Inventors:

Richard W. Boeglin - N. Kingstown RI
Arthur B. Joyal - Bristol RI

Assignee:

Raytheon Company - Lexington MA

International Classification:

G01V 138

US Classification:

367154

Abstract:

A seal of flexible waterproof material joins two shells, or a shell and its end plate, which are spaced at their edges to have a separation or gap between them into which the seal material loops. The seal material is attached to each shell, or to the shell and its end plate, to effect a watertight seal at the joint. When one joint edge moves radially with respect to the other edge, a low friction rolling action of the seal material accommodates the motion with low frictional resistance and low energy loss.
