Appl. No.:

12/583568

Inventors:

Robert Parker - Panama City FL, US
David Robinson - Panama City FL, US
Anthony Simpson - Panama City FL, US

Assignee:

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

International Classification:

G12B 9/00

US Classification:

220584, 114312

Abstract:

The invention in one variation is a pressure vessel having a pair of hemispheres with a wall and a circular edge, a pair of sealing elements, and an intervening mounting plate with circular groove on both sides of the plate. The hemispheres are mounted on opposite sides of the plate. Each groove has an sealing element and the circular edge. A seal is formed between the plate and a hemisphere when the hemisphere is pressed against the sealing element. Pressure can be generated by creating a partial vacuum in the sealed hemispheres or by using clamps. When exposed to higher pressures, such as when the vessel is used underwater, the pressure on the hemispheres is conveyed to the sealing element forming an even tighter seal. The vessel has interface connections that enable communication to and from devices mounted inside. The vessels are modular and can be ganged to provide redundancy or different functions.

Abstract:

A brake mechanism for a beam trolley on a beam has a body member on the beam trolley adjacent the beam. The body member has a recess and axially aligned bores and a rotatable lateral pin extends through the aligned bores. The lateral pin has a rotatable elongate cam portion extending across the recess, and a brake pad is in the recess adjacent to the beam and abutting the cam portion. A handle is connected to the lateral pin for rotating the pin and the cam portion to displace the brake pad against the beam. The brake pad frictionally secures the beam trolley on the beam and locks the rotatable cam in place. Rounded end portions on opposite ends of the lateral pin and sleeve-like bushings between the axially aligned bores and rounded end portions permit rotation of the cam portion by the handle.
