Abstract: An outdoor battery cabinet is formed to include a cooling system to extend the life of the housed batteries. The cooling system comprises a ventilation system including an air intake unit, an exhaust unit and a thermostat control. The interior surface of the cabinet is covered with a layer of insulative material. The ventilation system is configured to turn "on" when the outdoor temperature drops below the interior cabinet temperature, thereby cooling the housed batteries. Once the outdoor temperature rises above the cabinet temperature, the ventilation system is turned "off" and the insulation in the cabinet functions to maintain the cooler ambient temperature within the cabinet. To minimize the effects of wind forcing air through the ventilation openings, the intake and exhaust louvers are located on the same side of the cabinet.

Abstract: An aerial fiber optic cable case comprises an elongated boxlike housing, openings at the ends of the housing for insertion therein from the side of an unbroken aerial fiber optic distribution cable and further insertion therein of the ends of one or more aerial fiber optic drop cables; seals for the passage of such cables through such openings, a tray reversibly mounted with the housing for supporting optical splices between one or more distribution cable fibers and one or more drop cable fibers, and a support frame including two hangers for fastening such case to hang from an aerial support strand. The container formed of the housing and lid is pivotably mounted relative to the hangers to be angularly movable relative thereto between forward and rear limit positions of angular tilt.

Abstract: A device for sealing passage of cable through an opening in a wall comprises (a) an elastomeric grommet having therein an axial bore and a radial slit extending to such bore from the grommet's outer surface, and (b) a clamp comprising a belt of which a segment forms a loop around the grommet, and a take-up adapted by adjustment to contract or expand such loop. In use, a portion of a cable is inserted through the slit into the bore, the grommet is positioned within the wall opening and the take-up is operated to contract the loop to pressurize the grommet material to thereby seal (c) the cable portion in the bore, (d) the slit and (e) the interface of the grommet and wall. Prior to such use, the bore contains a removable plug joined to the grommet by a ring of tearable material. The grommet has thereon first and second flanges adapted to, respectively, provide strain relief for the cable and aid in retaining the grommet in the wall opening.

Abstract: Splices between conductors in of an aerial telephone cable are covered by a closure located within a terminal. The closure has a large central section connected via tapered joints to two end sections. A settable liquid encapsulant is received in the central section. The closure has two halves joined by a flexible hinge that runs lengthwise along a first longitudinal edge. Two rigid tabs of nonuniform thickness running lengthwise along a second longitudinal edge are secured by snaps through apertures in the tabs. The snaps have tapered sections that clamp the varying thickness rigid tabs along their lengths to prevent leakage of liquid encapsulant. The end sections have open cell foam strips fitting snugly between the cable and the end section walls which are fixed with the liquid encapsulant. The encapsulant sets within the open cell foam to form a barrier to passage of contaminants into the central section.
