  • Patent number: 5151961
    Abstract: An assembly for axially aligning two ferrules comprises a first housing, an alignment sleeve carrier, an alignment sleeve retained within a passage of the alignment sleeve carrier and a nut for securing the alignment sleeve carrier to the first housing such that a leading end of a first ferrule received in a passage of the first housing can extend into the alignment sleeve. The assembly further comprises a second housing, a socket member and a spring clip for securing the socket member to the second housing. The socket member has a through passage for receiving a second ferrule at one end and a leading end of the alignment sleeve carrier at another end such that the second ferrule can extend into the alignment sleeve for axial alignment with the first ferrule when the alignment sleeve carrier is received in the passage of the socket member.

  • Patent number: 4286121
    Abstract: A manual cutover apparatus activates a plurality of circuit boards in an equipment frame in a telephone switching facility. Each circuit board is provided with a manually operable switch for inhibiting the function of the circuit or disabling a line termination at the circuit board, while the switch is in contact with an elongated control member. The control member spans the board locations in the frame and is held in place by slots in a connector shroud at each board position. When the frame is empty of circuit boards, the control member is inserted into slots in the equipment frame. After the required circuit boards are placed in the frame, these boards are activated by the withdrawal of the control member through a hole in a frame member at one end of the frame. The switch includes a base with a pair of terminals and a cantilever spring switch member extending over a groove in the base.
