Filed: 1975-04-23
Abstract: 1452445 Connecting wires to printed circuit boards; bending; assembling force fits; shearing GTE INTERNATIONAL Inc 23 April 1975 16915/75 Headings B3A B3E B3U and B3W [Also in Division H2] A wire 3 is force fitted into a slot extending from an edge of a circuit board 1 by locating the wire 3 between the edge of the board 1 and a probe member 7 and moving the probe member 7 relative to the board 1 to locate the wire 3 at the mouth of the slot and then to drive it into the slot. A wire 3 is connected between printed circuit boards 1 mounted on a co-ordinate table 4 by lowering a slide block 29 carrying a probe member 7 to bring a spring loaded pawl 45 below the end of a tubular needle 33a so as to bend the wire 3 extending from the needle 33a. An inner needle 6 within the needle 33a and containing the wire 3 is lowered to feed the wire 3 which is gripped by collets 88, 89 against the pawl 45 to form the wire end into a U-shape which is engaged by a probe member 7 carried by an adjacent slide block 30. A head unit (68), (Fig. 10, not shown), on which the blocks 29, 30 are mounted is pivoted about a vertical shaft (17) to trap the wire 3 between the edge of the board 1 and the probe member 7. Fluid pressure is applied to a ball piston (77), (Fig. 9, not shown) to move the probe member 7 laterally until the wire 3 has been located in the slot in the board 1, whereupon the head unit is pivoted with a greater force to force the wire 3 into the slot. With the wire 3 clamped in the slot, the wire 3 is fed through the needle 6 by reciprocating the feed collets 88, 89 by a solenoid (44), (Fig. 11, not shown), or a piston and cylinder unit to form a loop below the board 1 (Fig. 15, not shown), whereupon the table 4 is moved to bring the head unit to a position adjacent the next slot in which the wire is to be inserted. After gripping the wire 3 with levers (52), (Fig. 13, not shown), cutters 54b, Fig. 14, are moved by a cylinder V towards the wire 3 to sever the insulation on the wire, after which a plate 56 carrying the cutters 54b is lowered by a cylinder T to bare the wire 3 and compress the insulation. The bared wire 3 is then forced into the slot by the probe member 7 on the slide block 29, after which the plate 56 is lowered to move a stop 58 into an inoperative position so that when the cutters 54b are moved inwards the wire 3 is completely severed. Finally, the insulation on the end of the wire 3 is stripped ready for the next fitting operation. Each circuit board 1 is coated with a resilient layer, e.g. p.v.c. to prevent fracturing of the wire 3 by the sharp edges of the slot in the board. In a final operation, the inserted wires are connected to the conductive areas surrounding the slots by solder. The cylinders of the machine may be replaced by electro-magnetic solenoids.

Title: Improvements in the control of the flow of alternating current through electronic discharge tubes
IPC: H02P3/18
Filed: 1932-06-15
Abstract: 403,408. Maintaining defined speeds of A.C. motors. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.- (Assignees of Brown, G. C.; West Milwaukee, Wisconsin, U.S.A.) June 15, 1932, No. 16930. Convention date, June 15, 1931. [Class 38 (iii).] An electronic discharge tube 10 is connected in circuit with a source of alternating potential and has impressed upon its grid an oscillating voltage adapted to be initiated in an oscillating circuit 17, 18, 19, in synchronism with the alternating potential, so that the tube is rendered conducting or non-conducting to the positive half waves of the alternating potential according as whether the frequency of the potential varies in one direction or the other from a given frequency. The invention is described as applied to a control system for an alternating-current motor 1 whereby the motor may be maintained at constant speed or "plugged" to rest. By closure of a push button switch 21 the motor is connected for forward rotation and by closure of a switch 23, secondary resistances 7, 8, are excluded. With the switch 23 open the speed of the motor is maintained constant. The voltage across sliprings S1, S2, is applied to the primary of a transformer 20, and to the tube 10, the secondary of the transformer charging the condenser 17, 19, during negative half-waves of potential applied to the tube 10. The tuning of the circuit 17, 18, 19, is such that with the motor speed above a certain value the grid potential of the tube 10 is never sufficiently positive during a positive half-wave to allow discharge. A relay 9 is accordingly de-energized, and rotor resistances 7, 8, in circuit. With the motor speed above this certain value the tube 10 discharges, and the relay 9 is energized, and the rotor resistance included. The condition of conductivity or otherwise of the tube 10 is made more definite by means of a condenser 12 in parallel with a resistance 13. The motor may be " plugged " to rest by pressing a " stop button 22. This de-energizes the " forward contactor 2, and closes the " reverse " contactor 3, the latter in closing removing the condenser 19 from the tuned circuit. At the same time rotor resistance is inserted, and, owing to the new tuning of the circuit 17, 18, the relay 9 is held closed to maintain the circuit of the contactor 3. When the motor has come to rest or reaches a speed determined by the new tuning of the circuit 17, 18, the relay 9 drops out, and the motor is disconnected.

Abstract: 227,734. Garbutt, W. O. Oct. 18. 1923. Dash-pots.-A device for limiting the frequency of operation of the lid i of a feeding-appliance for animals consists of a dash-pot 1 having a piston 3, with a valve 7 therein, attached to a rod 4 linked to the lid 1. Air is forced through a bypass 10 when the piston 3 is raised, causing liquid from a reservoir 9 to pass up through a valve 12, Fig. 2, into the dash-pot below a loose piston 8. An adjustable return orifice 13 allows the liquid to pass slowly back to the reservoir 9. If the lid is operated several times at short intervals, the liquid collects below the piston 8 which is lifted into contact with the piston 3 and prevents the closing of the lid i.

Title: Method for covering tubular articles with synthetic organic plastics materials

IPC: B29C63/20
Filed: 1962-05-04
Abstract: 1,045,143. Applying flexible tubing, e.g. to metal pipes. ENFIELD-STANDARD POWER CABLES Ltd. May 3, 1963 [May 4, 1962], No. 17196/62. Headings F2G, F2P and F2S. ) A covering of synthetic organic plastics material having an interference fit with a tubular article is applied over that article whilst being distorted by reducing the surrounding pressure and is subsequently pressed against the surface of the article by bringing the surrounding pressure to above atmospheric pressure. The article to be covered, for example, a metal tube 8, is placed inside the covering, for example a polythene tube 1, in a tube 2 forming part of an exhaust chamber. The ends of the polythene tube are warmed and stretched and are sealed inside holes in the end walls 5, 6 of the chamber. The polythene tube is shown enlarged due to vacuum applied through a pipe 7. The metal tube normally has an interference fit with the polythene tube and therefore the polythene tube shrinks on the metal tube when vacuum is released and the pressure raised above that of the atmosphere. To guard against misalignment due to deflection, the metal tube may be supported internally, or the covering may be applied with the tube vertical. Fig. 4 (not shown), shows an arrangement which allows the polythene tube to contract in length as it expands in diameter, because the outer tube 2 of the exhaust chamber is made telescopic at its end 13 and a bellows 14 is incorporated. To cover a pipe joint between two such tubes, a polythene tube 17, Fig. 6 (not shown), may be prepared by radially expanding an undersize tube whilst it is softened by heat and cooling it to freeze it at the larger diameter. The expanded tube is then placed over the joint and reheated, when it shrinks into position. Collars may be placed around the tube 8 under the ends of the tube 17.

Abstract: 595,534. Polishing wheel rims. DUNLOP RUBBER CO., Ltd., SHACKLETON, A., and WHALE, G. H. July 6, 1945. No. 17257. [Class 60] Apparatus for polishing wheel rims and the like has a frame member with at least three rolls to position the rim relative to polishing mops, and driving means for said rim. and is so constructed that movement of the frame from an operative to an inoperative position releases the rim from the driving means, the polishers and the positioning rolls. Two independently driven, adjustably inclined, parallel polishing mops 2, 3 are located in a structure 1 so that they bear on different halves of the inner periphery of a wheel rim 6. The rim 6 is supported by a spring-pressed roll 8 and a diametrically opposed fixed roll 10, both contacting the outer periphery, and a spring-pressed roll 9 contacting the inner periphery opposite to a driving roll 11 engaging the outer periphery, all the rolls being mounted on a frame 7 pivoted on trunnions 34. When the frame is moved from an operative position, as shown in Fig. 4, to an inoperative position, as shown in Fig. 3, a bent arm 13, pivoted at 14 to the frame 7, under the action of a roller 15, on one end of the arm 13, on a cam surface 16, moves the rolls 8, 9 out of contact with the wheel. The frame 7 is locked in the operative position by a plunger 23 engaging a recess in a web member 24 on the frame. A pedal 22 which operates this locking means also simultaneously operates the piston-rod of an air cylinder 21 to close a shield 18 pivoted to the frame 7. In a modification, the rolls 8, 9 are moved by hydraulic means which also tilts the frame 7 and moves the shield 18 ; a stop on the structure 1 is provided, no locking means being necessary.
