Abstract: A combined connector and valve, for example, for connection of an air line to a source of compressed air or to a vacuum source (all for use in an hydraulic fluid line) the connector comprising a one piece housing (112) a spring-loaded valve member (130) located in a bore (118) in the housing. The valve member (130) is removably retained in the bore by means of a threadedly engaged cap (134). A standard spring-loaded sleeve (140) is slidably located on the open end of the housing (112) to provide a means of connection, and a standard ribbed stem (114) may receive a hose at the remote end.

Abstract: An inflatable hose system which may act as a boom for rescue purposes or for controlling the flow of surface borne contaminants of rivers, lakes and seas and comprising first and second hose lengths each having one en flattened and sealed to be chiselshaped and the other end provided with a coupling. The two lengths and any interposing standard hose lengths may thus be coupled together and inflated to a pressure in the range of 2 to 3.5 bar to provide a boom of the required length, and one of the hose lengths includes an inflation valve. The hose length may be connected together in mutual alignment thus to produce a straight boom or with the interposition of elbows to form a curved boom capable of containing floating objects or substances.

Abstract: A coupling for connecting a vacuum line to a body such as an autoclave to be evacuated, the coupling having a first part adapted to be sealingly engaged by welding upon the wall of the autoclave about an aperture therein, and having an internal bore which thus communicates with the interior of the autoclave, and a second part also having an internal bore for communication with the bore of the first part. The second part thus serves as a removable cartridge which is slidably engaged within the first part with sealing rings radially and axially sealing the two-parts together to prevent fluid leakage therebetween. The cartridge includes a spring-loaded valve. A circlip enables separation of the cartridge from the first part, and a circlip enables removal of the valve parts from the cartridge.

The valve cap (134) has surface formations to enable it to be unthreaded from within the connector for retrieval of the valve member (130) for maintenance or replacement.

Abstract: To avoid sealing problems associated with attachment of a connector to a separate valve member when providing for evacuation of a bag or other container, a unitary connector and valve (10) comprises a spring-loaded valve member (24) located in a bore (20) in a housing (12), which has external clamping (40-46) enabling the housing (12) to be sealingly attached to a container (not shown) as well as a fitting (48) enabling the housing (12) to be attached to an air line (not shown).
