A bore contact having a gas port is attached to a snuffer tube of the assembly and has fixed to it a piston adapter for driving the snuffer-contact assembly toward the open end of the container tube in response to gas generated by arcing inside the bore. Resilient sliding contact means are fixed to the piston and press against the inside wall of the container tube to establish continuous electrical contact with it even while the piston is moving.

Abstract: A portable, prefabricated panel adapted to be connected with a plurality of similar panels to form a wall or partition structure. The panel is electrically prewired and includes electrical power blocks disposed adjacent the opposite lower corners of the panel, which power blocks are connected by electrical cables which extend internally of the panel. When two or more panels are connected together, electrical power is transmitted between each adjacent pair of panels by a flexible electrical connector which plugs into the power blocks of the adjacent panels. The panel also has electrical sockets integrally associated therewith, which sockets are preferably associated with the power blocks. The power blocks are symmetrical so that the same electrical connections can be made on either side of the panel. A channel-like raceway extends along the bottom edge of the panel for permitting the hidden storage of communication cables.

Abstract: A machine for bringing the flexible upright walls of paperboard containers into a predetermined configuration, so that fitment rings may be applied to the upper ends of those containers, includes a pair of captivator chains having parallel inner passes and a main conveyor located generally between the two inner passes. The containers are released onto the main conveyor at equal intervals, whereupon opposed captivator blocks on the two chains fit snugly around the containers and cause them to assume the desired configuration. This enables fitment rings to be installed over the upper margins of the sidewalls or some other operation to be performed on the containers.

Abstract: The tube socket is especially adapted for use with a longitudinal extending cathode ray tube of the type having one or more high voltage pins and a plurality of relatively low voltage pins. The socket provides structure for spark gap grounding of the high voltage pin or pins, with or without spark gap grounding of the low voltage pins, the latter spark gap protection being essentially conventional. The structure is inexpensive and easy to mold and assemble as compared with prior art socket structures performing the same or equivalent functions.

Abstract: Each welding cable terminal component, such as a semi-cylindrical terminal half, near its rearward end is provided with a semi-cylindrical recess in which the cable conductors are received and held in position by a clip in the form of an endless band having a partially cylindrical external portion snugly fitting a corresponding external semi-cylindrical groove in the terminal component. A chordal inner portion of the clip is pressed forcibly into compressing engagement with the ends of the cable conductors within the recess, whereupon molten solder is flowed into the recess under the clip between the hair-like wires of the strands of the cable conductors, thereby forcibly holding the cable conductors firmly in the recess while the solder permeates the entire cable conductor ends within the recess. The terminal components of which there are at least two, are then assembled with an insulating strip between them and clamped together, as by bolts.

Abstract: A lampholder for a medium bi-pin fluorescent lamp has a combination slot permitting either "straight-in" or "turn-lock" insertion.

Abstract: An electrical connector in which two rows of resilient contacts are mounted in a connector housing on opposite sides of a slot which is adapted to receive a printed circuit board or similar electrical component therein. The end portion of the spring contacting section of each contact is reversely bent in a direction away from the slot. A vertically movable contact shifting element is disposed between the spring contacting sections and the reversely bent end portions of the contacts in each row of contacts. A cam actuator is operated to move the contact shifting elements upwardly against the reversely bent end portions of the contacts thereby deflecting the spring contacting sections away from the slot so that a printed circuit board may be inserted therein with zero insertion force. Teeth are provided on the contact shifting element and cam actuator which interlock and thereby restrict upward movement of the contact shifting element except during operation of the cam actuator.

Abstract: An integrally molded housing has a dead-front base and a pair of side covers pivotally connected to it by web hinges. The side covers fold about the web hinges to: (i) force cord conductors into insulation displacement terminals affixed to the housing and thus wire the connector; (ii) safely enclose the wiring area; and (iii) lock the side covers to the dead-front base by the engagement of mating portions of the covers and base to prevent relative motion even should the web hinges fail. The connector can have male or female contacts or both. It provides speed and convenience of wiring and assembly and ensures quality wiring by eliminating the variability in workmanship associated with conventional stripping of conductor ends and screw tightening used for screw type terminals.
