Abstract: A snap-in strain relief (10) is provided for insulated cable wires (23) spread across and solder connected to thin metallic terminals (22) formed on a printed circuit board (11). The strain relief is constructed in the shape of a bar (32) having a projecting cleat (36 or 58) at one end which fits into a slot (37) or hole (62) formed in an edge section of the circuit board, and a projecting post (44) with a headed lobe (46 or 57) at the other end which is force-fitted into a hole (43) formed in the circuit board. Standoffs (47 and 48) are formed on the underside of bar to insure that the bar does not crush the insulation of the wires while applying a force to hold the wires and force isolate the soldered connections against pulling forces imparted to the cable (24).

Abstract: A coiled section (16) of a plastic sheathed stub cable (10) is placed on a support (43) which is orbited about a longitudinal axis of a straight section (13) of the stub cable. The straight section of cable is positioned coaxially within an aperture formed in a casing part (12) which is mounted in a rotating nest (16). The juncture (70) between the apertured casing and the cable sheath is heated (81), whereafter a bead (91) of bonding material is extruded around the juncture. A molding die (106) is moved into the extruded bead to force portions of the bead into the juncture to form a homogeneous weld with the cable sheath and casing parts while uniformly shaping the remaining portions.

Abstract: A portable tool is provided to assemble washers (13) and nuts (14) on threaded studs (10) extending from a frame member (11,12). Pneumatically operated pushers (43,54) advance a polygonal-shaped nut and a round washer into a polygonal-shaped chamber (24) formed by a sleeve (26) and a polygonal-shaped driver rod (29). The end of the sleeve is placed over a threaded stud and forced against the frame member, whereupon a clutch (32) is disengaged and rotative power is applied to the driver rod and the sleeve while the driver rod is moved within the sleeve to push the washer and the rotating nut onto the threaded stud. The clutch in the engaged position is constructed so as to insure that slots (63 and 64) in the sleeve (26) are aligned with the pushers (43 and 54) to permit entry of the washers and the nuts into the chamber where they are magnetically held.

Abstract: A continuous strip (16) of metal with boxed discrete capacitors (10) assembled thereon is cyclically advanced to move a leading section of the strip into a positioned chamber (48) of a multi-chamber magazine (46). After a predetermined number of advancements of the strip, a cutter (76,83) is operated to sever the strip and then an auxiliary feed device (107-118) is rendered effective to advance the trailing extremity of the severed strip into the magazine chamber. Immediately thereafter the magazine is indexed to position another chamber to receive a subsequently advanced section of the strip. Upon loading of a magazine with a strip and assembled capacitors in each chamber, facilities (127-142) are rendered effective to advance a new magazine into position to receive additional sections of the strip with the assembled capacitors.

Abstract: A boxed and encapsulated rolled metallized film capacitor susceptible to facile machine insertion is fabricated by cyclically advancing a lead frame 32 through a number of stations (36,37) whereat pairs of leads (24,26) of the lead frame are bent downwardly and secured to end electrodes (22,23) formed on the capacitors, and then boxes (29) partially filled with encapsulant are moved over each capacitor secured to a pair of leads. Next, the lead frame is advanced to move each box and capacitor into position to receive additional encapsulant from a nozzle (38) which is projected through a feed hole (34) formed in the lead frame.

Abstract: A pair of very thin dielectric films, each completely metallized on one side, are positively advanced over a pair of drums of a machine while the films are laser scribed and slit to form two sets of film strips each of which has a laser scribed capacitor plate formed thereon. The film strips forcibly emanating from the drums pass through a number of tension responsive devices and are wound on one of a pair of successively positioned takeup split mandrels. A compensating mechanism is included in one of the drum drives to vary the speed of the drums to compensate for the difference in diameters of the wound convolutions of one set of film strips with respect to the other set so that a succession of capacitor blanks are snugly wound with consistent geometric size and capacitance value.

Abstract: A rolled metallized film capacitor is encased between a pair of box halves (13 and 13') each having a pair of dovetailed slots (36 and 37) formed in opposite walls so that when the box halves are assembled about a capacitor blank (10) the slots in the respective box halves are aligned with each other. The box halves are mounted in abutting relation about a pair of parallel wires (11 and 12), and then heat fusible metal (46 and 47) is deposited in the aligned slots to lock the box halves together while bonding the wires (11 and 12) to opposite ends of the capacitor blank (10). When assembled, the boxed capacitor with the laterally extending leads may be readily machine inserted or otherwise assembled in a circuit module, such as a printed circuit board.

Abstract: A small rolled metallized film capacitor is completely encapsulated within a thin walled box with bonded terminals projecting from an open end of the box. The terminals are formed with offset shoulder sections resting on and extending laterally beyond the opposed walls of the box. The terminals are further shaped and formed to provide narrow insertion sections that project from the shoulder sections in generally normal but slightly diverted directions.

Abstract: A rolled metallized film capacitor blank and a pair of terminals are assembled in a small plastic box. The terminals are heated by an electric circuit to bond the terminals to heat fusible electrodes formed on the opposed ends of the capacitor blank. The terminals are provided with serrated or metal deforming sections which bite into the engaged end electrodes during assembly of the capacitor blank in the box to insure good contact during the subsequent electrical heating step.

Abstract: A stable hoist for loading and unloading articles (10) onto and from shelves (11) includes a base housing (12) from which extends a cruciform-shaped standard (13). A slide arrangement (14) mounted on the standard and driven by a power source (46 and 47) mounted in the housing moves a boom (16) up and down. The boom comprises a slide (20) and a trolley (21) from which depends a clamp (22) to grip the article. Inverted L-shaped arm structures (28 and 29) extend from the crossarms (26 and 27) of the cruciform-shaped standard (13). Stabilizing plates (48 and 49) are pivotally mounted in arm sections (33 and 34) to engage the shelf during a loading or unloading operation. The weight of components mounted in the base housing (12) and on the cruciform-shaped standard (13) act to counterbalance the tilting force during a loading and unloading operation.

Abstract: A rolled metallized film capacitor is manufactured by completely metallized one surface of each of a pair of dielectric films, and advancing the films while laser scribing patterns of demetallized lines on the respective films which are wound together to provide a pair of capacitor plates of finite areas. As the films are advanced the laser scribing is controlled so that when the films are wound together, the lines on the respective films are in overlaying relationship on the core and peripheral windings, and are diverted to opposed marginal edge portions of the respective films on the intervening windings. When the rolled capacitor films are terminated and connected to a power source the opposed metallized areas on the core and peripheral windings are subjected to equal potentials, whereas the remainder of the windings present two metallized areas between the opposed margin lines which are subjected to potential of opposite polarity to accumulate charges and function as capacitor plates.

Abstract: A pair of pointed terminals are heated and forced through opposed side walls of an open-ended box constructed of thermoplastic material. A rolled film capacitor blank having heat fusible end electrodes is moved into the box to deflect the terminals so that the terminals are forced into firm engagement with the end electrodes. The heated terminals are effective to soften or melt the engaged portions of the electrodes to bond the terminals to the capacitor blank.

Abstract: A zero force connector is constructed of a plurality of tiers of jack-like units (16, 17, 23 and 24) which are simultaneously opened and closed by turning a pair of screws made of sets (31 and 32). Each screw set has left and right-hand threads to cooperate with threaded ends (26,27) of the jack units so that all the jack-like units are moved to engage a plurality of tiers of plugs 10 with minimum sliding forces, thus, preventing abrading of precious metal plating on the contacting elements (13, 14, 18 and 19).

Abstract: A rolled metallized film capacitor is terminated with bimetallic terminals. A method of manufacture of this terminated capacitor contemplates inserting a capacitor blank with heat fusible end electrodes in a plastic box to position the electrodes between a pair of "L" shaped bimetallic terminals constructed of laminations of materials having different coefficients of expansion. The terminals extend through opposed walls of the box and are heated to flex feet of the terminals into firm engagements with the end electrodes whereupon the heat is effective to bond the terminals to the capacitor blank. Encapsulant is deposited in the box to provide a moisture seal while also assisting to hold the terminals in the bonded positions.

Abstract: A two-hand safety system utilizing an operator's skin resistance is provided to control the operation of a work fabricating tool. An operator must place both hands on a pair of spaced electrodes in order to initiate operation of a radio digital signal generator which transmits a digital signal to a receiver. The receipt of the digital signal in conjunction with a predetermined positioning of a freely slidable work holder energize a circuit to control the operation of the work fabricating tool.

Abstract: This disclosure is directed to the vapor condensation heating of articles to an elevated temperature so as to perform, for example, a soldering, brazing or fusing operation thereon, without requiring the immersion of the articles within the heat transfer liquid-generated body of hot saturated vapor. This is accomplished in accordance with several methods and apparatus which allow the saturated body of vapor to controllably rise to and heat only a selected underside surface area (or areas) of each article, in succession, while minimizing the loss of any vapor to the atmosphere at all times.
