Abstract:
An individual subscriber circuit protector module employing solid state circuitry for protection against momentary voltage surges, and having firmly sensitive heat coil assemblies for protecting against continuous excess current surges. Fail-safe protection is also provided which becomes operative in the event of failure of the heat coil protection.
Abstract:
A rigid waste container having a bottom and walls and a peripherally depending rigid shift for offsetting the bottom of the container from a support surface. The skirt has one or more spaced orifices and affixed to the underside of the bottom of the container is a ratchet bar. A holder for a package of waste container liners is mounted on the side of the container. The holder includes a pawl arm, an upright member joined to the pawl arm and a pawl escapement tooth formed on the pawl arm. The holder is located through the orifice of the skirt so as to be in slideable engagement with the ratchet bar. This arrangement is adapted to receive a supply package of liner bags located between the upright member and the wall of the container. The supply package is of sufficient resiliency so as to permit locking engagement of the package between the upright member and the container. The holder is formed of one piece construction and is flat prior to assembly. The holder may be bent into an L-shape configuration and is retained in this configuration by a latching mechanism.
Abstract:
Coaxial connectors include a connector body and an inner contact post. A compression sleeve is also provided that is configured to impart a generally circumferential compressive force to secure one or more elements of a coaxial cable between the connector body and the inner contact post when the compression sleeve is in a seated position. The compression sleeve or the connector body includes a first disengagement mechanism that is configured to assist moving the compression sleeve from the seated position to an unseated position in which at least some of the circumferential compressive force is eliminated.

Abstract:
Adaptive racking and distribution frame systems for handling optical fiber cables and including racking sections with wall portions that can be replaced without removing the section or displacing cables in the section and further including housings with moveable shelves that can be adapted to hold optical fiber splices, optical fiber connectors or optical fiber storage spools.
Abstract:
An optical fiber storage and distribution cabinet of molded plastic box-like construction with U-shaped formations open through the bottom wall of the cabinet to provide an easily molded door hinge and spool-like fiber storage elements which also serve to mount a removable splice tray. The splice tray has cable and fiber guide formations and splice holding means which allow fiber entry and exit from different directions.

Abstract:
A fail-safe secondary fuse device for assuring the grounding of a conductive gas tube used in modular protection devices for individual subscriber circuit pairs. The device resiliently engages each of the three end and center electrodes normally provided on the tube. In the case of the end electrodes, the device is insulated from direct electrical communication by a fusible sleeve of insulative material which fuses under heat emanating from the gas tube with the occurrence of continued current overload.
Abstract:
A solid state protector module for individual subscriber circuits particularly suited for use with laminar type quick clip connector blocks. The module comprises a printed circuit board mounting integrated circuit protector units which are thermally sensitive. Solder preforms are resiliently urged against integrated circuit units by a shorting spring, mounting the solder preforms allowing the shorting spring to ground the individual circuit. The solder preforms including a camming circuit allowing the shorting spring to urge the preform perpendicularly to the normal direction of spring movement.
