  • Patent number: 5174661
    Abstract: A method and apparatus for mounting a rotating part between two bearings designed to transmit radial and axial forces without axial and radial play. Each bearing includes a rolling element positioned between an outer part and an inner race surrounding the shaft end. Each bearing also includes a conical sleeve in contact with an inclined surface of the inner race. A nut is threaded to the outer end of the conical sleeve such that rotation of the nut causes the centering of the shaft end within the bearing. The outer part includes a chamfer surface into which extends a shim. A screw is rotted to cause the shim to compress the outer part downwardly toward the inner race. The method for mounting the rotating part also includes the use of a stepped shoulder at one end of the housing to prevent axial movement of one of the bearing members. The opposite end of the housing does not include a stepped shoulder so as to allow easy insertion of the second bearing member.

  • Patent number: 4557292
    Abstract: Stage for a system for distributing pneumatic control signals by electrical means, comprising a large number of associated stages. Each stage comprises a removable electrical valve (141) having an electro-magnet (33) of very low power, and a fixed socket (5) into which it fits: a pneumatic amplifier (57) is housed in the body (51), of the socket and feeds relatively large amounts of fluid to an outlet connector (26) when it is activated by the outlet of a low flow pneumatic switch (40); a non-return valve (88) protects the amplifier against pressure perturbations in the discharge duct (4). Numerous thin stages of a thickness close to 17.5 mm. can with advantage be used as an interface between a pneumatic installation (28) and a control center (24) supplying low level electrical signals.

  • Patent number: 4402254
    Abstract: A progressive pneumatic starter device delivers at its outlet an increasing pressure of low flow rate, then a working pressure at a high flow rate. The starter device is provided with a distributor member adapted to connect, in parallel with a calibrated bore, a channel of large section, when a pressure which is greater than a predetermined threshold and which is not derived from the outlet is applied to the distributor member. The starter device is advantageously placed upstream of a pneumatic switch to which it is directly associated for the purpose of shortening its channels for transfer of fluid.

  • Patent number: 4245673
    Abstract: A sequencing logic circuit comprises a blocking means for preventing phase jumps caused by the untimely presence of a release signal. An inhibitor device is placed on one of the channels feeding a storage relay, placed upstream of said release signal, in such a manner as to prevent the transmission thereto of a pressure for placing it in logic state "1." This inhibitor device is actuated by the release signal and does not permit any communication between the latter and the channel controlled.

  • Patent number: 4238748
    Abstract: The invention relates to a magnetically controlled switch with contacts wetted by a conductive liquid. It is characterized in that the wettable contact surfaces of the electrodes are selectively connected to one another by a wettable ferromagnetic moving element covered with mercury which is held solely by the surface tension forces of the mercury. The absence of any polarizing force and the lightness of the moving element enable the switch to operate with a minimal energy consumption and stabilize it against accelerations. Principal application to any low-power circuit and in particular to telephone circuits.
