Abstract: A pressing tool for electrical connectors, or the like, including an elongated housing, an anvil carried by the housing adjacent one end thereof, a presser carried by and movable relative to the housing toward and away from the anvil along a presser path perpendicular to the anvil, an elongated handle extending longitudinally of the housing and accessible from the exterior thereof, means connecting the handle to the housing for producing longitudinal movement of the handle relative to the housing in response to lateral movement of the handle relative to the housing, and means for converting such longitudinal movement of the handle relative to the housing into movement of the presser along the presser path toward the anvil. Reversed movement of the handle is prevented until the presser has been moved a predetermined distance toward the anvil.

Abstract: A cable transfer system for a telephone central office main frame and cable vault. A cable transfer panel for permanent or temporary connection to the main frame while positioned remote from the main frame, and providing for interconnection of up to 200 line pairs at a time with a single switch operation for each interconnection. A cable transfer panel also providing for cross connecting of line pairs and for connecting of test equipment to the line pairs, as desired.

Abstract: A re-enterable enclosure, or enclosure kit, for use with a cable splice, including two axially spaced, longitudinally split tubular members having inner and outer ends and converging toward their outer ends and having external radial locking ribs respectively extending longitudinally along the edges of the slits therein. A longitudinally split coupling sleeve is adapted to be telescoped over the inner ends of the tubular members. Each tubular member is adapted to be locked against circumferential expansion by a locking strip telescoped over the locking ribs of the corresponding tubular member from the outer end thereof.

Abstract: A re-enterable enclosure, or enclosure kit, for use with a cable splice, or the like, including, among other elements, a longitudinally split tubular member which is sufficiently flexible and resilient that the edges of the slit thereof may be spread to permit lateral application of the tubular member over a cable splice, or the like, the tubular member having external radial locking ribs respectively extending longitudinally among the edges of the slit therein, and a locking strip of generally H-shaped cross section including two outer flanges and two inner flanges interconnected lengthwise thereof at their respective junctions by a web, the outer flanges respectively having internal longitudinal grooves therein adapted to receive the external locking ribs on the tubular member to prevent spreading of the edges of the slit in the tubular member, the web of the locking strip being insertable longitudinally into the slit in the tubular member from one end of the tubular member with the outer flanges engaging t

Abstract: This invention is directed to liquid polyurethane compositions made from a prepolymer and a curing solution. The prepolymer is made from organic diisocyanate, aliphatic triol, and liquid organic plasticizer material compatible with the composition and having an NCO content of about 1.2-2.5%. The prepolymer is cured with a solution composition of urethane curing agent, liquid organic plasticizer compatible with the cured composition, and an organo-metallic catalyst effective at ambient temperature. The cured polyurethane composition is a resilient solid which is waterproof and crumbles under shearing force applied to the surface or interior of the solid to permit easy breakaway or reentry into a cable splice or a surface which is encapsulated, embedded or coated with said solid.

Abstract: A split cover plate for a telephone outlet comprising two interlocked plate forming members which overlap sufficiently to receive two attachment screws through each plate forming member, thereby providing the assembly of plate forming members with essentially the same rigidity as a one-piece cover plate.

Abstract: An improved high-capacity solderless bonding assembly for shielded cables having a current carrying capacity in the order of 1,000 amperes for in excess of 15 seconds. The assembly includes a U-shaped metal strap of good conductivity material having one leg insertable beneath a cable shield together with strong ferrous metal fastener means extending through aligned openings of the strap legs as well as the cable sheath and shield, and effective to clamp one strap leg against the shield and the other leg to the outer end of the fastener means thereby utilizing the strap and the fastener to share the electrical load. The fastener means extend through aligned openings in the legs of the U-shaped strap and through the cable sheath and shield.

Abstract: An enclosure and enclosure kit for encapsulating a splice or splices between main and service cables, the enclosure containing a potted compound which prevents the entry of moisture into the splice or splices. The enclosure is re-enterable to permit the addition or deletion of service cables, the potting compound being of a type which is readily removable to permit adding or deleting service connections. More particularly, the enclosure kit includes a re-closable, longitudinally split tubular housing and re-closable, longitudinally split end caps telescopable over the ends of the tubular housing, together with a supply of potting compound adequate to completely charge the enclosure, or to replace potting compound removed upon re-entry. Readily releasable locking elements are provided to close the longitudinal splits in the tubular housing and in the end caps, such locking elements also resisting circumferential expansion of the enclosure components mentioned.

Abstract: A turn-back protector securable within the return bend of a multi-conductor sheathed cable to limit the minimum radius of a return bend in the cable thereby protecting the cable from too severe bending. The protector is particularly useful in connection with butt cable splices and cable dead ends, whether under ground or above ground.

Abstract: Cable reclamation method and apparatus by which moisture is precluded from entering or is purged from an electrical cable by injecting a two-part polymerizable compound in liquid phase into and along the cable. Any moisture present is purged through an outlet port distant from the compound entry port. The compound takes a permanent soft-solid set at normal ambient temperatures within a few hours as a paste-like gel readily removable at any future time to permit cable splicing and servicing operations. This soft-solid gel forms a moisture-proof nonconductive sealing barrier precluding entry of moisture and restoring normal cable operating conditions. The compound supply tank is pressurized with air or gas to transfer the compound in liquid phase into the cable, the pressurized gas being used initially to agitate and intermix the compound constituents.

Abstract: A conductor terminal block and a mounting member therefor having provision for detachably holding one or more blocks snugly but detachably assembled to one or both faces of the mounting member. As shown, each block includes a pair of threaded studs to which conductors can be clamped. The one-piece mounting member is molded of resilient non-conductive material and includes a pair of resilient latches to which a respective terminal block can be snugly assembled. A tool serves to deflect the latches and release any block independently of the others. The conductor terminal connecting capacity is readily expandable upon need by adding one or more terminal blocks and one or more terminal block mounting members.
