Abstract: Cutters for removing excess weld material from elongated welds are moved by hydraulic cylinders into precise positions in proximity to the article having the welds to maintain the desired uniform thickness of the welds. The movement of the hydraulic cylinders is controlled by tracer control valves having operating elements engaged by members connected to sensing rollers which engage the article as the article is moved past the sensing rollers. The positions of the rollers and the cutter are adjustable to accommodate articles of various sizes.

Abstract: A connective-protective adapter for use with a silo-type cathode ray tube base provides both connector pin protection and electrical connective means for all active pins of the tube. The adapter permits affixation of the permanent base to the tube early in tube processing, thereby eliminating the need for temporary processing bases, and provides pin protection on the finished tube.

Abstract: First and second connector housings are keyed to each other by means of identical parts which can serve as either keys or keyway plugs. The identical parts are produced as a continuous strip comprising a carrier strip from which the parts extend at spaced apart intervals. In the practice of the invention, a section of strip is used which has a number of parts thereon equal to the number of keying positions in the connector assembly. One or more of the identical parts are removed from the strip and assembled to the first housing. Thereafter the remaining parts on the strip are aligned with the keying positions on the second housing and assembled to the second housing. The carrier strip can then be separated from the remaining identical parts.

Abstract: An electrical connector includes a female member and a male member. The elongated female member has a flat base portion and a pair of opposed retaining arms formed integrally on the base portion and extending along opposite lateral edges thereof to form a retaining portion of a generally channel-shaped cross-section. Each of the retaining arms has a side portion extending from the base portion and a distal end portion extending from the side portion. The side portions of the respective retaining arms are inclined inwardly toward each other. One end of the male member is adapted to be inserted into the retaining portion for being resiliently held by the retaining arms and the base portion to make an electrical connection between the female and male members.

Abstract: By providing an input/output module which incorporates post means formed thereon and slider means connected thereto and movable into and out of locking engagement with the post means of an adjacent module, a unique input/output module is achieved that is rapidly mounted to an adjacent module as well as rapidly disconnected therefrom. Preferably, each input/output module incorporates mating connector means positioned on opposite surfaces thereof, whereby each input/output module electronically directly connects to an adjacent module for communication with a central processor.

Abstract: A supply connector for an electrical distribution track (1) consisting of a channel housing longitudinal conductors (4) comprises a body (7) carrying contacts (18) for engaging the track conductors, and a polarizing member (23) which cooperates with the track to permit one orientation of the connector in the track, the polarity of the connector being reversible by rotating a member (21) which carries wiring symbols (L,N) to indicate the correct connections between the suuply leads and the terminals for the polarity selected.

Abstract: An elongate header for mounting a connector. The header includes a series of insulative L-shaped segments each including a base having an aperture for receiving a header post and further including a resilient, deflectable wall extending from the base. Adjacent segments are joined by interconnection means sufficiently thin that a group of segments can be broken away by hand from the remainder of the segments. The header also includes a post disposed in each aperture, the locking means for cooperating with a component of the connector to lock the connector, once mounted to the header. Finally, the header includes polarizing means for preventing reverse mounting of the connector on the header. Headers of a predetermined number of segments can be removed from an indeterminate length of such segments to preclude the need for a user to carry an inventory of headers of different lengths.

Abstract: In order to provide a more compact package for economical storage and shipment, of a vacuum cleaner, or the like, the handle is manufactured in two portions. The two portions are configured to fit together in a predetermined manner with a telescoping relationship and to concomitantly complete electrical connections through connectors which are affixed to and internal to respective handle portions. At least one of the electrical connectors is allowed some longitudinal and rotational motion relative to its handle portion to facilitate electrical connector engagement and alignment. The assembly is held together by a fastener passing through the telescoped handle portions and one of the connectors. A portion of one of the connector assemblies also serves to limit the excursion of a compression spring surrounding a portion of the associated handle portion.

The insulating member 30 may be attached to both members 10 and 50 with the attachment to the cover member 10 being stronger than the attachment to the rear member 50. The pins of an electrical plug pass through openings in the cover member to electrically contact the conductors 70,71,72.

Abstract: A self-locking electrical connector is disclosed in which a locking ring is mounted in an annular groove in the interior of a coupling nut on the plug of the connector. When the plug is mated with the receptacle, inwardly extending projections on the locking ring ride up over a low-angle ramp on the shell of the receptacle and then snap into a locking groove formed in the receptacle shell behind the ramp to lock the connector members together. The surface of the locking groove next to the low-angle ramp is formed as a high-angle ramp which allows removal of the projections of the ring from the groove when the coupling nut is rotated with high torque to unthread from the shell. In an alternative embodiment, the locking ring is carried by the receptacle shell, and the locking groove and angular ramps are formed on the inner surface of the coupling nut.
