  • Patent number: 4746768
    Abstract: Insert has a plate member supporting one or more transition blocks for interconnecting power conductors from the power cell to the conductors of a flat cable together with an adjusting ring supporting a cover with a cable exit slot. The cover, the adjusting ring, and the transition block provide for the cover and transition block to be angularly oriented to correspond to the direction from which the flat conductor cable exits to the insert. The arrangement provides for the flat connector cable to exit the insert from several different azimuthal directions and with the power conductors being connectible with the transition block.

  • Patent number: 4745717
    Abstract: An adaptor to interface a poke-thru with power cable sets of a flexible wiring system. The adaptor has: an elongated, hollow housing with an axially extending opening; a support inside of the housing having a center section and a head, the center section extending across the opening and the head which has an opening for power conductors extends across the interior of the housing; a wire connector mounted on the center section of the support member and accesible through the housing opening; and a hollow, axially extending barrier inside of the housing and resting the head, the interior of the barrier being in communication with power conductor passageway in the head. The portion of the housing not closed off by the center section serves as an entrance to the adaptor for communication cables. The barrier and the head isolate the communication cables from the power conductors.

  • Patent number: 4741221
    Abstract: The combination of a lead screw and a multi-ball nut. The balls are disposed around the axis of the lead screw. The balls are mounted on the nut either to be received and retained in the valley of the lead screw thread (whereby rotation of the lead screw causes movement of the nut along the lead screw in one direction for a feed operation) or for the balls to be movable out of the valley onto the crest of the thread. The latter condition permits the nut to be moved along the lead screw in a reverse direction for a quick return operation.

  • Patent number: 4685912
    Abstract: A flexible tube is mounted on top of the drip chamber. The top of the tube is connected to the spike via a one-way ball-type valve. The bottom of the tube is connected to the drip chamber via a duck-bill-type valve inside of the drip chamber. The duck-bill is held closed against head pressure by a metal spring clip acting on the lip. The duck-bill will open when the tube is squeezed and fluid will be injected into the drip chamber.The drip chamber is charged bubble-free by the use of an output tube open to the chamber and joined to the flexible tubing carrying the hypodermic needle. During the initial fill the output tube is positioned above the fluid level and air in the chamber vented via the output tube, the flexible tubing and the hypodermic needle. When the desired level is reached, the output tube is submerged and bubble-free fluid fills the output tube, the flexible tubing, and the hypodermic needle.
