Abstract: An automatic coupler for pressurized fluid circuits is divulged of the type comprising a valve (19) sliding in a body (1), and means for balancing the upstream fluid pressure on the valve. The downstream portion of the latter forms a socket for receiving and sealingly locking a connector (8). The coupler comprises a means for locking the valve in two positions: one in which the valve is open and the other in which it is closed and the socket communicates with the atmosphere, the connector (8) being still locked. Release of the valve from the first position engages a locking means in an intermediate position whose release causes locking in the second position. The coupler of the invention reliably prevents the "whiplash" phenomenon produced, at the time of uncoupling, by the downstream pressure.

With the device, an element may be quickly fixed while working from only one side of the wall.

Abstract: Disclosed is an improvement to the passage of pressurized liquids through masonry work using hollow plastic material boxes (17) embedded in pairs in a masonry work (2) and connected together by sheaths (3) also embedded in the masonry work (2) and fixed to the boxes (17). The pressurized liquid plastic material pipes (4), pass through the masonry work (2) through boxes (17) and sheaths (3) in which they are installed by axial sliding motion with diametrical play. The boxes (17) have wheels with a curved profile (11, 13) which hold each pipe (4) in position and bend it while it is guided laterally in a deep grooved curved over a 1/4 of a circle (17i), without friction. With rolling contact of the pipe (4) on the wheels (11, 13), the pipes (4) pass through and are bent from the horizontal position to the vertical position with a minimum axial thrust. Through the free rolling of the wheels (11, 13), it is easy to install them or change them. The boxes are sealed with respect to liquid cement.

An inlet channel 4 in element 2 and an outlet channel 3 in element 1 each equipped with an integrated connector 66 and 55 open into their respective adjacent faces over the same circle of radius XY. The angular registration of these orifices allows the sealed bidirectional passage of the fluid of the device by means of a seal 8 housed in a cup 7 at the periphery of channel 4 and compressed between the two elements 1 and 2.

Abstract: A method and device for assembling connection fittings such as couplings, between hard components, such as metal pipe and a body formed of a softer substance to obtain a permanent coupling able to withstand aging and thermal shock conditions. The parts coupled are formed of materials of different hardness which are first force fit together. One of the parts is then rotated at high speed so that the part made of the softer material is locally heated until it melts. The result is a snug but swivelable connection free of internal stress.

Abstract: Improvement in pneumatic sensors for the control of pneumatic cycles, in which a liquid jet vacuum pump is supplied at the input by a compressed air circuit and connected at the output to a nozzle of which the obturation provokes a rise in pressure in the vacuum pump used as signal for controlling a pneumatic component.
