Abstract:
A series of individual telephone subscriber circuit modules for use with telephone connector blocks having flat insulation displacement clips projecting from a planar surface thereof. The block mounts a grounding strip medially positioned on said surface. The modules employ known protection components, and in various modifications, are suitable for providing alternatively three point protection or five point protection utilizing either or both of gas tube and fuse components. Depending upon specific requirements, each module protects either two or four subscriber circuits.
Abstract:
A wastebasket includes a container having a top opening, and a lid mounted on the container and adapted to pivot about a pivot axis to cover and uncover the top opening. A mechanism for actuating pivotal movement of the lid with respect to the container is provided. The mechanism includes a generally horizontal operating lever having a foot pedal, a depending flange joined to the lid, and a rod linkage interconnecting the operating lever and the flange. The lid flange has an elongated slot formed through its thickness. The slot includes a channel and two enlargements situated at opposite ends of the channel. The rod linkage slides through the channel into one of the two enlargements, and engages the lid flange at either enlargement to pivot the lid between positions covering and uncovering the container. A U-shaped member having legs is pivotally mounted on the lid flange and is adapted to pivot with its legs across the elongated slot near one of the enlargements to help keep the rod linkage from inadvertently slipping out of the enlargement and into the channel of the slot when lid is being pivoted to a position uncovering the container.
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:
A hand-held tool for the convenient attachment and disconnection of conductors to individual insulation displacement terminals on a telephone connector block. The device includes a first member for serially inserting the free end of a conductor into a resiliently expandable slot in the terminal, and severing the end of the wire which projects from the slot at a predetermined length. A second remotely positioned member provides for the engagement of the conductor for removal of an unwanted connection. The last-mentioned member also includes structure for the engagement of a protector module overlying the terminal for purposes of removal of the same to gain access to the conductor.
Abstract:
A laminar type telephone protector block of quick clip type including grounding means incorporated into the individual laminae, and a novel protector module of gas tube type communicating with said grounding means.
Abstract:
A multiple cradle structure for use in supporting a plurality of cradle-mounted telephone connector blocks upon a main frame or backboard wherein the wired blocks may be pressed into position to be supported thereon. The cradle is configured to provide separate passages for outside plant cable and inside office wiring so as to maintain cross talk and noise on individual subscriber pairs at a minimum.

Abstract:
An improved telephone subscriber circuit protector module providing plural surge voltage and excess current protection elements including so-called sneak current protection. The module includes a three-element gas tube which protects against voltage surges in the range of 200 to 300 volts, and includes fail safe protection relative to the gas tube should the gas tube become non-conductive over its intended range of protection. The fail safe protection is thermally operated under the influence of high current. Secondary air gap protection supplements the operation of the gas tube in the event of gas tube failure, and is operative to ground momentary voltage surges in the area of 1500 volts. Separate sneak current protection employing heat coils are operative in a range below one ampere flow, and an alternate form provides for the opening of the subscriber side of the line rather than the grounding of it. All of the protective elements communicate with a common ground plane forming part of a ground assembly.
Abstract:
An individual telephone subscriber circuit module for use with laminar type connector blocks employing conventional three-element gas tubes of diameter greater than the thickness of an individual lamina. The module houses two gas tubes in side-by-side relation and straddles two adjacent laminae on the block to protect a pair of adjacent circuits.
