Abstract: A ceramic chip carrier package for integrated circuits is described which provides reduced interlead capacitance. A cavity for the placement of the integrated circuit chip is centrally located on a substrate. The leads of the package are bridged between the cavity and the outer periphery of the substrate. The leads are bonded to the substrate using adhesive glass placed on the substrate at the outer periphery of the cavity and at the outer periphery of the substrate. Sealing glass is placed on the outer periphery of the substrate over the leads to provide a bonding material for a lid to the package. The area between the cavity and the outer periphery of the substrate has no adhesive or sealing glass which thus provides an air dielectric between the leads so that interlead capacitance is reduced.

The slidable cover member is movable between an open position at which access to underlaying electrical outlets is available through the slidable safety cover and a closed position at which access to the electrical outlets is blocked by the slidable cover member. Movement of the slidable cover member from the closed position to the open position requires release of a locking mechanism comprising at least one resilient finger latch member having a first end portion anchored to the stationary frame and a second end portion partially protruding through the slidable cover member. A finger latch opening is provided in the slidable cover member and is located distal from all sides of the safety cover slidable cover member.

Abstract: Apparatus for use in providing an electrical connector having a plug receptacle with protection from intrusion therein of foreign matter comprises a resilient membrane adapted for disposition in contiguous overlying relation to the connector. The membrane has a flat undersurface and extends therefrom to a preselected maximum thickness and therewith defines at least one recess extending from the undersurface for receipt of the connector plug receptacle. The membrane defines a pad distal from the undersurface by the extent of the recess. The pad includes a portion of thickness greatly reduced from the membrane maximum thickness and positioned for registry with a prong of the plug and readily penetrable thereby to sealingly seat the prong in the receptacle. The membrane may include a further pad penetrable for sealed passage of a communication cable therethrough. The membrane is comprised of a material adapted to self-close the membrane portion upon withdrawal of the prong and communication cable therefrom.

Abstract: A floor electric wire junction case includes a bottom block covered with a cover plate defining a plurality of wiring passages therebetween for respectively receiving a plurality of junctions which can be respectively connected to wiring connecting tubes. Each wiring bracket has a circular hole at its top for mounting a wiring plug assembly.

Abstract: A trunking assembly for electrical cables comprises a channel section housing having a longitudinal opening defined by the inturned edges of its side walls. Mounting rails extend along the free edges of the inturned side walls within the channel section and a backing box for an electrical component such as a socket outlet is adapted to be fitted within the channel section and fixed to the mounting rails by a clamping ring. The assembly of the backing box and clamping ring is a snap fit within the housing and longitudinal adjustment of the assembly along the rails can be achieved prior to locking in position. When locked in position, the backing box and clamping ring improve the integrity of the housing by preventing significant deformation of the side walls.
