Abstract: A modular jack for telephone and data equipment test access ports including a cover having substantially the same thermal coefficient of expansion as its housing, and which is integral with the housing to prevent its being lost during usage or testing. The cover extends inwardly of the housing, to rotate further inwardly, automatically, upon the insertion of the plug into the housing to complete the electrical circuit.

Abstract: An insulation displacement contact (IDC) strain relief cap to interconnect a wire with an electrical contact is disclosed. The strain relief cap has a “U” shaped end to engage and retain the wire and is engageable with the contact. Means in the form of two star shaped openings are provided on the strain relief cap to retain the wire whereby the electrical contact, wire, and strain relief cap may be moved as a single unit. The star shaped openings and “U” shaped member allow for flexible retention of the wire to the strain relief cap.

Abstract: A modular plug assembly is provided which includes a modular plug body, and an insulation displacement connector (IDC), having a terminal body and a terminal strip. The assembly is formed to engage a wire, including a multi-conductor wire, and be inserted into a modular jack to form an electrical connection between the wire and the modular jack. Any length of wire can be used, and in the preferred embodiment of the invention, the assembly engages the wire in a toolless manner.

Abstract: A system for organizing optical fibers includes a pedestal, a bracket and a fiber splice tray. The pedestal has a longitudinal passage through it. The pedestal has at least one hole on its side surface. The hole penetrates from the longitudinal passage to an exterior of the pedestal. The bracket is mounted to the pedestal near the hole. The bracket is capable of receiving and storing a plurality of fiber splice trays. Preferably, the pedestal includes a plurality of holes located around its perimeter and a plurality of brackets located between respective ones of the plurality of holes. Each tray is movable between a vertical position for storage and a horizontal position for accessing a fiber on the tray. The assembly has a single base mounted on the pedestal below the plurality of holes, at a distance from the bottom of the pedestal; and a single cover that joins with the base to form a sealed enclosure around the plurality of brackets and the fiber splice trays.

Abstract: A modular jack receptacle that includes a plurality of removable interfaces that provide for interconnection between and among the plurality of interfaces and a modular jack held by the receptacle. Each of the removable interfaces include two terminals mounted on a printed circuit board and each connected to a circuit trace. Each interface may also include, as a routine matter of design choice, electronic devices, circuits, connectors, etc., to provide for additional functionality of the interface. The modular jack receptacle provides increased flexibility in diagnostic and test capability for a particular communication line from a Central Office (CO) to a customer premise location and simplified replacement of electronic devices installed in series with a communication line.

Abstract: A latch for securing the cover to the housing of a network interface device including a shaft having a bayonet-type projection at its tail end rotatable to lock with one of two tabs fabricated as part of the housing, and with a stop projection at its opposite end to capture the shaft within the cover. In a preferred embodiment of the invention, the housing, the cover, the tabs and the shaft are all constructed of a substantially plastic composition, and with a controlled rotation of ±90° from the quiescent insertion of the shaft for locking and unlocking the network interface device in allowing for automated manufacture and assembly of the interface device in telephone and data equipment test accessing port.

Abstract: A tool to remove an insulation displacement contact (IDC) strain relief cap that interconnects a wire with an electrical contact. The electrical contact has a bifurcated end to engage and retain a wire and is engageable with the strain relief cap to secure The wire. Means in the form of tabs are provided on the electrical contact to releaseably retain the electrical contact and the strain relief cap together with the wire whereby the electrical contact, wire, and strain relief cap may be moved as a single unit. The tool has tangs to engage the tabs and move them out of engagement with the relief cap while gripping the relief cap for removal from the electrical contact.

Abstract: A contact wire connector includes a housing connected to an insulation displacement contact (IDC) and a contact sleeve. A strain relief member is connected to the housing opposite the IDC. The contact sleeve connects to a pin of a substrate and the IDC connects to an insulated wire which establishes an electrical connection between the substrate and the insulated wire. The strain relief member engages the insulated wire to maintain the electrical connection in an unstrained state.

Abstract: An insulation displacement contact (IDC) strain relief cap is employed to interconnect a wire with an electrical contact. The electrical contact has a bifurcated end to engage and retain a wire and may be engaged with the strain relief cap. The cap contains notches, some of which fit on retaining cams that are attached to the electrical contact while others serve as wire exit holes. The cap fastens onto the clip once the retaining cams engage the notches and once the wire is aligned with the appropriate exit hole.

Abstract: A mechanically sealed insulation displacement connector includes a contact and a wire holder. The wire holder has a channel for receiving an insulated wire and a slot for receiving the contact. One end of the channel has a conical shaped region which provides a positive stop for an inserted wire. The positive stop causes the insulation of the inserted wire to press against the inside surface of the conical region when the wire is inserted into the channel. The insulation is slightly deformed providing an inexpensive and effective seal for the wire's conductor without the use of gelled oils and greases. As the insulation is pressed against the conical shaped region, the wire holder is rotated enabling the contact to move into the slot where it pierces the insulation and grips the conductor of the wire, thereby making an electrical connection and holding the insulation against the conical shaped region.

Abstract: A tundish veneer composition comprising about 45-80 percent by weight of MgO, about 1-7 percent by weight of a refractory clay filler, about 1-15 percent by weight of a refractory glass wool fiber, about 3-10 percent of aqueous colloidal silica binder, and optionally, up to about 15 percent by weight of graphite, a foaming agent, or a dispersing agent.

Abstract: System for handling and applying a non-suspended refractory slurry to ingot stools used in the production of steel ingots, including an apparatus capable of selectively applying refractory slurry to ingot stools which receives slurry from a storage tank. An agitator is provided in the tank to continually agitate the slurry, and wet air is used to clean the lines carrying the slurry when they are not being used for application of slurry to prevent clogging.
