Abstract: Automatic device for economizing compressed air comprises a means for ensuring the passage of driving fluid under pressure during most of the stroke of the moving element of a user apparatus. The device consists of a single-unit body having a first circuit connecting a fluid supply pipe to one chamber of the cylinder actuator. The first circuit is controlled by a valve moving with a piston subjected to the action of an elastic means and slidably mounted in the body. The piston is actuated by the presence or absence of a pressure signal, the body having a second circuit by-passing the first circuit and connecting a fluid exhaust pipe to the cylinder chamber.

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.

Abstract: A valve that is connected to a container of pressurized fluid and has a spring-loaded striker member which is normally secured in a ready position out of contact with a seal retaining the fluid within the container, the striker member being releasable by the action of a releasable lock for movement by a loading spring into an operate position in which the striker member perforates the seal to release the pressurized fluid. The lock is responsive to a control member to lock the striker member against movement when the control member is in a non-operating position, and to release the striker member upon arrival of the control member at an operating position. Movement of the control member is effected by a releasable connector which connector is further responsive to the arrival of the control member at the operating position to then release the cable allowing the escape thereof.
