  • Patent number: 4813879
    Abstract: A connector device is provided for receiving a smart card having a plurality of electric contact areas distributed along a forward edge. The device has a reception case having a card introduction passage with a stop limiting insertion of the card. Flexible contact blades are placed so as to bear on the areas and to exert on the card a force tending to move it away from the stop; a resilient bolt is carried by the case and cooperates with a cam formed on the end part of the card. The end part of the card, the cam means and the bolt have a construction such that full insertion of the card and return under the action of the blades cause locking of the card in a set contact position and that a second thrust exerted by the card frees the cam means from the bolt.

  • Patent number: 4767180
    Abstract: A device makes a non-permanent connection between two optical fibers each fixed into a respective fiber holding device from which a bared end of the fiber protrudes. The device comprises a socket member featuring a guide member to accommodate the aligned bared fiber ends. A clamp member in line with the guide member immobilizes the bared fiber ends by clamping them against the guide member. Two mobile plug members are each adapted to interlock nesting fashion with the socket member, one on each side of the guide member. Their axes are at a predetermined angle to the guide member. Each plug member comprises a front surface through which it comes into an abutting and supporting relationship with the other plug member. At a rear end of a central channel in the plug member is a receptacle for the fiber holding device.

  • Patent number: 4753689
    Abstract: The invention relates to a method of conditioning an object in shape-memory material of metallic alloy type.The object formed to final shapes and dimensions constituting the first shape-memory state is submitted to a thermal treatment in order to bring this object to an austenitic crystallographic phase, then to cooling. The object is then submitted in at least one deformation zone to a process of education consisting of imposing on the object, in at least one cycle, a series of thermal and/or mechanical stresses. The stresses are such as to lead to deformation of the object for bringing it to a shape close to its second shape-memory state in a martensitic crystallographic state, then to permit the return of the object to its first shape-memory state, on a return of the object to the austenitic crystallographic state.Application to electric contact elements.
