摘要： An armored cable structure which converts a plurality of stranded flexible wire ropes for suspending and retrieving the cable structure in a bore hole into members which are also rigid in longitudinal compression and constrained against birdcaging. The converted ropes serve as positively drivable members for forcing the cable structure and any equipment attached to the down-hole end thereof down-hole.

摘要： A reinforced cable having hauling, electrical and hydraulic lines. The cable has a substantially rectangular cross section and includes at least one internal support to protect these lines by resisting external compressive forces, and yet is bendable about one of its transverse axes for easy storage on and deployment from a drum. The internal support also protects the hauling lines from compressive forces applied longitudinally thereof by resisting radial displacement of the hauling lines. In one embodiment, the cable comprises an armor layer, a pair of engaged channels inside the armor layer, and a pair of corrugated supports inside the channels and fixedly spaced apart. The hauling lines, in the form of wire ropes, are located inside the corrugated supports, while the electrical lines are located inside the channels between the corrugated supports. The hydraulic lines can alternatively be located inside the channels between the corrugated supports, or inside the wire ropes. Any spaces inside the channels are filled by elastomeric material. In another embodiment, the cable comprises a rigid tubular support located between and engaging the wire ropes, and an armor layer engaging and enclosing the tubular support and the wire ropes. In this embodiment, the electrical conductor is located inside the tubular support.

摘要： A resilient gasket for a weatherproof electrical outlet provides seals between the outlet box and the cover plate, between the receptacle and the cover plate, and between the cover plate and cover flap or plug connected to the receptacle. The gasket is a planar member having a peripheral configuration corresponding to the peripheral configurations of a standard outlet box and cover plate therefor and is received between the cover plate and receptacle and between the cover plate and outlet box. At least one aperture extends through the gasket and has transverse dimensions, in a relaxed condition of the gasket, less than the similar dimensions of projections on standard electrical receptacles. Upon assembly of the gasket within the electrical outlet, the portions of the gasket adjacent the aperture are stretched and deformed out of the plane of the gasket to provide a peripheral lip which extends through the cover plate opening, surrounds the receptacle projection, and contacts the cover flap in its closed position or the plug connected to the receptacle. In this manner, a single, unitary and continuous gasket is provided for the electrical outlet.

摘要： A general purpose receptacle having selective single and split circuit electrical modes is adapted for mounting in a standard floor or wall mounting box. The receptacle is formed of a molded, one-piece receptacle body and a molded, one-piece receptacle front. Selection of single or split circuit operating modes is achievable by a break-off tab which normally electrically connects two sets of female contacts as a single circuit but which can be broken off so that the female contact sets are electrically separated. The receptacle is wired by placing the unstripped ends of insulated conductors at insulation severing terminals connected to the female contacts and forcing the conductors into the terminals. To accomplish this, a pair of suitably shaped side covers are hinged to the front part of the receptacle top to provide the requisite insulation-displacement forces. With the side covers secured in position, no terminals are exposed which might otherwise make electrical contact with metallic parts of the mounting box. Mounting, insulation severing and circuit mode selection can all be performed by using a screwdriver.
