Title: A method of fitting a resilient sleeve about an electrical connector and means for carrying out the method
Inventor: HILLS BRUCE
IPC: H01R43/04
Filed: 1969-10-06
Abstract: 1,245,315. Two-part couplings. AMP Inc. 6 Oct., 1969 [14 Oct., 1968], No. 48975/69. Heading H2E. [Also in Division B3] A method of fitting an insulating sleeve SL, e.g. of silicone rubber or a polypropylene plastics material, about an electrical connector EC comprises inserting a pair of expanders 56, Fig. 3, into one end of the sleeve, separating the expanders to expand the sleeve, inserting an end of wire W through the expanded sleeve from its other end so that the wire projects beyond the said one end, crimping the connector to the projecting end, pulling the wire to draw the connector into the sleeve and removing the expanders from the sleeve to allow it to contract resiliently about the connector. Apparatus for performing the method comprises an attachment 38 fixed to a conventional crimping press which includes dies 4, 6 for crimping the connector about the insulation and the conductor of the wire, a blade 12 for severing the connector from a strip of connectors, a feed finger 24 operated pneumatically for advancing the strip and a ram 2 operated by an electromotor. The attachment includes a slide 42 operated by a pneumatic cylinder 44 and having trunnions 46 guided by slots 48. Mounted on the slide are pneumatic cylinders 52, Fig. 3, carrying the expanders 56. The sleeves SL are secured by contact adhesive to a plastics tape T, which is drawn from a reel by a spool driven intermittently. Operation.-Upon operation of a pedal switch, an electronic timing circuit (not shown) causes the actuator 44 to move the slide 42 to the left for inserting the expanders 56 in the operative sleeve SL1. The expanders are now separated by their cylinders 52 and, upon a return stroke of the slide 42, strip the sleeve from the tape T. The operator then inserts the wire W through the sleeve from the left, so that the end to be crimped is located above the operative connector EC1, or within the connector if this has annular, rather than U-shaped, crimping sections. Crimping now occurs, controlled by the timing circuit, after which the operator retracts the wire W, drawing the connector into the sleeve and pulling this from the expanders 56.

Abstract: 1,115,720. Reciprocating dynamo-electric machines. M. BARTHALON. 2 Nov., 1966 [17 Nov., 1965], No. 49059/66. Heading H2A. In an electromagnetic reciprocating compressor, the armature consists of a cylindrical magnetic plunger which is drawn intermittently into a radial field and is directly coupled to the piston. As shown in Fig. 1, its simplest form, the armature 4 works in the annular air-gap between poles la, 2 which are preferably of sintered material and are energized by coil 3 fed with half-waves through diode 3c. The armature is also of sintered material to reduce eddy-currents, and it works against an aircushion formed under piston-head 6. Cooling air is drawn by the underside of the piston through holes 17, 18 which align at the extremity of the return stroke, and is then pumped along channels 20 in the centre pole to the air space 22 round the working coil 3, the remaining air acting as return cushion. It is described how two such armatures may be used, one on each aide of the core (Fig. 3, not shown). The armature may be composed of annular laminae and be spring-returned. The armature has lubricating strips of P.T.F.E. between the laminµ. In an alternative arrangement. Fig. 4, a pair of armatures 56a, 56b are connected to a single, double-acting piston 61, one on each side. Each works in an annular field core as described. The piston has a radially projecting flange 62 serving to pump cooling air round the field coils from ventilation volumes 60a, 60b, through suction valves 64 (see Fig. 9, not shown) and through cooling passages, not shown, round the coils. In addition, air entering at ports 68a, 68b is compressed and delivered at valves 65a, 65b, in the central poles. It is described how the principle of the invention is applied to a free-piston I.C. engine, the armature reciprocating between concentric arrays of radial, wound poles. The armature acts as an inductor, modulating the flux to generate in a coil on a common return path.

The output from the signal inverter 55 along a line 60 is identical with the inverter input along line 52 and a second output from the inverter 55 along line 62 is completely inverted relative to the inverter input on line 52. The lines 60, 62 are connected to a switcher 65 which switches between the non-inverted and inverted signals on lines 60, 62 to produce an output 68 identical with the original signal before inversion and recording. The sync. separator 58 detects the positive horizontal sync. pulses and produces a signal which is fed to a phase detector circuit 70 and time constant circuit 71 and then to a multivibrator or oscillator circuit 72. The multivibrator 72 controls a gate pulse generator 73 which controls the switcher 65 to ensure the correct switching frequency. A delay and saw-tooth generator 90 is also driven by the multivibrator 72 and is connected to the phase detector 70. An additional gate pulse generator may be driven by the multivibrator 72 and connected to the sync. separator 58 to further control its operation. The gate pulse generator 73 may be formed by an AND gate and an additional input to this gate may be applied from the horizontal key pulse circuit of a television set reproducing the picture from the output 68. In an alternative embodiment the gate pulse generator 73 is omitted, the delay in the delay and sawtooth generator 90 being changed at the same time.
