Abstract: A flexible supporting sheet formed of insulating material has "printed circuit"-type adherent conductors thereon which are flexible with the sheet and which are so disposed that contact parts which are also carried by the sheet, and which are arranged to be connectable to the individual components of a row of circuit components, are located at the ends of relatively long, straight, parallel hinging portions of the conductors, all of which hinging portions are arranged on the same side of the respective components to which they are to be connected. The sheet can be cut on three sides of each component, and its connected hinging portions of the conductors, to enable bending back an overlying tongue-like section of the sheet for access to the component without severing any of the conductors.

Abstract: A connecting and latching mechanism in an electronic apparatus is activated by a portion of the housing of a complementary electronic device as it is inserted for interconnection and charging. Varying sizes of devices can be accommodated. Three rotatable elements, two pawls and a connector arm, are mounted on a single base plate. One pawl keeps the connector arm from being damaged before device insertion and helps position the device upon insertion. A connector block on the connector arm is rotated into position for contacting the terminals of the device by a second portion of the device housing. When the connector block is in full contact with the terminals, the connector arm is latched by another pawl. A lock must be deactivated by key or manually operated button to release the latching pawl, the connector arm and the inserted device. Rotatable charging contacts provide scouring motion at the contact points and also accommodate devices of varying lengths.

Abstract: A current collector for connection to a current rail having current conductors in its side walls. The collector has a housing from which a coupling member having laterally directed electrical contact fingers projects. An element which screens the contact fingers and provides protection against touching the live parts of the device is rotatably mounted about the coupling member.

Abstract: A retaining device for preventing withdrawal of an electric plug from a wall or extension cord socket responsive to forces exerted on a cord connected to the plug. The devices of the first and second embodiments are fastened to a wall adjacent a conventional wall outlet. The devices frictionally engage the cord so that forces exerted on the cord are not transmitted to the plug.

Abstract: A self-attaching receptacle box adapted for use with light fixtures to afford a quick connection for the light fixture wiring to a source of current comprises a rectangular housing having in one wall thereof an opening for receiving the wires and a projection adjacent one edge of the opening, and a slotted opening in said wall opposite the projection through which extends a clamp portion of a block. The block has a threaded opening to receive a screw extending from an adjacent wall member which permits the block to be moved toward and away from the wire-receiving opening to clamp the projection and clamp portion of the block against opposite edges of a standard knock-out opening of the light fixture or other supporting panel.

Abstract: A pin type jack-and-plug coupling device is joined together by inserting the pin plug of a male connector into the pin jack of a female connector. The male connector has a captivated nut member and the female connector has an externally threaded member engageable with the nut member. After the pin plug has been inserted in the pin jack for electrical connection, the nut member is turned for threaded connection with the externally threaded member, whereupon the male and female connectors are lockingly joined together. The male connector also has a retainer nut for fastening the tightened nut member to prevent loosening.

Abstract: A housing made of insulating material has a plurality of slots each accommodating a contact spring including a pair of legs. The free ends of each leg are formed as contact noses facing each other. The contact noses define an opening through which an edge of a printed circuit board may be inserted with the board held at an angle with respect to its final position. The printed circuit board is then rotated about an axis parallel to the edge into its final position in which it is locked by a pair of resilient detent tongues formed at the ends of the housing. In this final position, conductor strips provided at the inserted edge of the printed circuit board make electrical contact with the noses of the contact springs. During rotation of the circuit board, minute sliding movements occur at the contact locations providing a cleaning effect on the contacts without causing excessive wear thereof.

Abstract: Disclosed is a method and apparatus for continuously stacking and discharging a predetermined number of flat folded, glued box blanks issuing from a folder-gluer without limiting the operating capacity of the folder-gluer. Provided is a conveyor means for depositing a predetermined number of blanks on a stacking table. Interposed between the conveyor and table are counter means and blank deflecting means. After a predetermined number of blanks have been counted, the counter activates the deflecting means and a secondary support means. The next following blank is deflected and engaged by a secondary support means and it and the following blanks are supported thereby until the blanks on the support table have been discharged and the table assumes the support of the new stack.
