Abstract: Through-the-wall hot and ground type improved stud connectors are disclosed for use being positioned through heavy duty motor vehicle battery box sidewalls, engine fire walls, dashboards and the like. The stud connector including a connector housing of conductive material including a threaded bore axially therethrough. First and second flat annular lands defining opposing ends on the conductor housing. The annular outer surface on the connector housing extends from the first annular land to the second annular land. A portion of the outer surface adjacent the second flat annular land is threaded. The invention resides in a threaded stud member of predetermined length being threadedly engaged with the threaded bore axially through the connector housing for providing adjustable length threaded stud mountings on opposing ends of the connector housing.

Abstract: Through the wall hot and ground type stud connectors are disclosed for use being positioned through truck and other heavy duty motor vehicle battery box side walls, engine firewalls, dashboards and the like. The stud connector includes a unitary conductive connector element with opposed first and second male connector ends and a radially enlarged central segment therebetween. In the hot type stud connector an overmold insulative member extends around part of the enlarged central segment and has a face that abuts a surface of a wall member and an annular flange that extends through a wall aperture to insulate the connector from the wall. An insulative nut member has a face for abutting an opposing surface of a wall member. A complementary cylindrical recess in the nut member slidingly receives the annular flange for fitting through various thicknesses of walls. The ground connector has a smaller overmold insulative member with a face for abutting one surface of a wall member.

Abstract: A cap is provided to cover the terminal heads of batteries and protect them from the elements. The cap is made of rubber or other pliable, non-conductive material and has a hollow cylindrical section and a planar section across the top of the cylindrical section. The cyclindrical section fits tightly over the terminal head, and the cap is retained over the terminal by the friction of the cylindrical section around the terminal head. The bottom of the cap seals against the insulated portions of a connector which is retained by the battery terminal.

Abstract: A cable clamp is provided for attaching a mid-portion of a cable having an electrically conductive interior surrounded by a non-conductive cover to a portion of a vehicle. The clamp includes a metal plate which is attachable to portions of a vehicle by a bolt extending through a transverse hole in the plate to secure the plate to the vehicle frame. A resilient elastomeric strap surrounds a portion of the length of the cable and surrounds the peripheral edges and a portion of the planar surface of the plate.

Abstract: A cable connector for attaching a cable having stranded wires enclosed in an insulated enclosure has a metal plate attached to the stranded wires. A threaded bolt is passed through an aperture in the metal plate and held in position by a nut. The parts, with the exception of the portion of the threaded shank extending beyond the nut, and the outer surface of the nut are hermetically sealed in an insulating enclosure. Finally a malleable sleeve of conductive material is fitted over a portion of the uncovered threaded shank of the bolt. When the shank of the bolt and the sleeve are passed through an aperture in a bulkhead or other conductor member, and a nut tightened on the end of the bolt projecting through the conductor member, the malleable sleeve is longitudinally compressed causing it to radially expand within the aperture in the conductor member.

Abstract: The present invention relates to a new and improved battery cable termination having an auxiliary terminal extending from one end of the termination in coaxial relationship with the associated cable.

Abstract: The present invention relates in general to battery cables and terminations for connecting electric cables to the terminals of batteries, and it relates more particularly to a new and improved termination for use with multiple connector cables and which incorporates an auxiliary stud which does not interfere with the fill holes of the associated battery.

Abstract: A self-contained jumper terminal assembly includes a battery terminal connector connected by an insulated cable to a remotely located jumper terminal for connection to one of the alligator clip connectors of a jumper cable. The jumper terminal is connected to one end of the insulated cable and an insulating cover member encloses the associated end of the cable and includes a mounting through-hole and a raised annular flange surrounding the mounting hole.

Abstract: A battery cable has a termination at one end for electric connection to the threaded terminal of a storage battery, which termination also includes an upstanding threaded stud for connection to another battery cable or to other auxiliary equipment.

Abstract: A battery cable termination includes a plastic housing incorporating a resilient sealing bead for sealing one termination to another termination which is stacked thereon.

Abstract: A first cable is spliced to an intermediate portion of a second cable by inserting an end of the first cable and a stripped intermediate portion of the second into a metallic tube, then forging the tube and cable portions together, then bending the first cable at a desired angle relative to the second cable, then soldering the cables and tube together, and then molding a plastic cover over the tube and exposed conductive portions of the cables.

Abstract: A terminal of a storage battery has an upstanding boss surrounded by an annular groove and a terminal plate has an embossment which fits against said boss and a resilient sealing being which is compressed into the groove by a bolt which extends through an opening through said embossment into a threaded hole through said boss.

Abstract: Low resistance in-line and end battery cable terminations incorporate a plastic cover which is molded over an apertured lug which fits over the battery stud and which includes a captured nut for attachment to the stud.

Abstract: A cyclic process for selective recovery of a metal from a material which contains other metal values in addition to the selected metal, comprises leaching the material with an aqueous solution capable of leaching metal values including the selected metal from the material. The resulting, aqueous solution, containing the selected metal and other metallic contaminants, is dispersed in an organic medium comprising an exchange reagent which is capable of selectively extracting the selected metal from the aqueous solution while rejecting any other metal values in the aqueous solution. The dispersion, comprising the aqueous solution and the organic medium containing the extracted metal, is passed as a flowing stream through a zone in which there are a plurality of spaced, parallel, elongate electrodes. Flow of the dispersion is such that it is distributed uniformly about the electrodes. An alternating current potential is applied to the electrodes to create an A.C.
