Abstract: An improved gel-protected registered telephone jack includes a cavity in a housing, and a rear opening to the cavity that permits positioning an insert that connects permanent telephone wires to spring connectors. A front opening receives a plug to make contact between wires in the plug and the spring connectors, and a gel on the spring connectors prevents corrosion of the connectors. Guides for the insert are mounted lower in the rear opening than is conventional and the housing adjacent the rear opening extends rearwardly more than is conventional, so the positioned insert is lower and more rearward than is conventional. A retainer binds the insert to the housing and thereby limits fore-and-aft translational movement of the insert within the cavity.

Abstract: An apparatus provides multiple telephone jacks for RJ11 and RJ45 connectors at an outlet box that has an installed telephone jack and holes to receive cover plate support screws. The apparatus includes a housing and a wiring board in the housing. The housing has an outlet box side and another side and generally has the shape of a rectangular parallelopiped with a minimal distance from the outlet box side to the other side to provide the appearance of a conventional outlet box coverplate with minimal protrusion into a room from the outlet box when installed. A telephone cord having a RJ11 or RJ45 plug connected to both ends of the telephone cord extends from the housing on the outlet box side to connect the installed phone jack to the multiple telephone jack apparatus. Further, surge protection circuitry, including an overcurrent protection device and a overvoltage protection device, is mounted on the wiring board to provide automatically resetting surge protection for the apparatus.

A telephone plug protrudes from the outlet box side of the housing to enable engagement with a jack mounted in the outlet box and includes a release lever to enable release of the plug from the jack. The housing has an access path to permit access to the release lever.

Abstract: A repeater case for high-density subscriber lines includes a repeater base and repeater case housing formed of a fiberglass composite and together forming a sealed enclosure for a pressurized atmosphere. The repeater case housing has a removable cover secured in position by torque bolts, a sealing gasket to sealingly receive the cover, a plurality of high-density subscriber line module slots and a plurality of printed circuit boards mounted to certain of the slots with gaps between adjacent printed circuit boards, the printed circuit boards being adapted to receive respective high-density subscriber line modules. The repeater base has a cable inlet, and each of the plurality of printed circuit boards is provided with a connection to the cable inlet and a connector to electrically receive one of the high-density subscriber line modules. The repeater base also includes an electrically insulating barrier between the cable inlet and the printed circuit boards.

Abstract: A pneumatic drilling chip removal system for removing drilling chips from a well bore, comprising sub-surface drilling equipment having a plurality of components and a drilling bit, a central passageway extending through the components and to the air jets in the drilling bit, wherein at least one component above the drilling bit in the sub-surface drilling equipment is a pneumatic component having an opening forming a pneumatic conduit from the central passageway to the annulus, a bypass valve disposed therein selectively permitting air flow from the central passageway to the annulus, forming a supplementary air source for removal of drilling chips from the well bore. Methods for using a pneumatic drilling chip removal system.
