Title: Improvements relating to welding a contact to a thermoplastic-insulated conductor
IPC: H01R12/67
Filed: 1964-10-12
Abstract: 1,075,799. Welding by pressure. ELCO CORPORATION. Oct. 12, 1964 [Oct. 21, 1963], No.41580/64. Heading B3R. [Also in Division H2] In welding the tail of a contact, the tail having a projection, to an electrical conductor having thermoplastic insulation, the cable is positioned between the tail and an electrode, the electrode is urged against one side of the cable so that heat from the electrode penetrates and softens the thermoplastic insulation, the electrode penetrates the insulation to engage the conductor and the projection penetrates the insulation to engage the conductor and an electric current is passed through the junction. To weld a terminal (12), Fig. 1 (not shown), having an upstanding projection (14) to one of the conductors (18) of a ribbon cable (16), the electrode (24) having a bifurcated nose (48) and heated by resistance or induction to approximately 250‹ C. is applied to the polyethylene insulation of the cable and penetrates to the conductor (18). The heat emitted by the electrode passes to the insulation on the other side and the projection on the terminal penetrates to engage the conductor. Condensers (32), (34), (36) are then discharged to weld the terminal to the conductor. A thermocouple (26) is associated with the electrode to maintain an accurate temperature. In a modification, the electrode has a single rounded tip and the projection on the terminal is formed by punching to form a recess opposite the projection. The depression caused by the electrode may be filled with epoxy sealing material and the welded joint may be associated with mechanical strengthening means.

IPC: H04M19/04
Filed: 1964-10-15
Abstract: 1,086,702. Audible signalling systems: POSTMASTER GENERAL. Oct. 13, 1965 [Oct. 15, 1964], No. 42137/64. Heading G4F. [Also in Division H4] A telephone sub-set ringer circuit which provides tone of increasing volume comprises a transistor oscillator VT and transducer TD which are shunted by the series combination of resistor R5 and a large capacitor C4: the charging of the capacitor by the rectified ringing current gradually removing the effect of the shunt to increase the current to the transistor and so increase the volume output of the transducer. The break-down of the Zener diode at a particular voltage across R5 changes the base bias to suddenly increase the volume. The capacitor C4 may either be discharged by means of resistor R7 as shown or by gravity switch operated contacts to stop the tone when the ringing current ceases or handset removed, respectively. In another arrangement the sensitivity of the transducer is adjusted to provide the increasing volume.

Title: Continuous production of thermo-plastic heat-shrinkable tubing
Inventor: MURRAY DUDLEY STUART
IPC: B29C48/10
Filed: 1969-08-25
Abstract: 1,272,808. Making heat-shrinkable thermoplastic tubing. D. S. MURRAY. 25 Aug., 1969 [30 Aug., 1968], No. 42193/69. Heading B5A. Heat shrinkable thermoplastic tubing is made by advancing a thermoplastic tube along a path and maintaining therein a difference in internal pressure levels at adjacent portions of the path by means of a plurality of clamping means which successively engage the tube and move with it, one of the clamping means being in engagement with the tube at any instant. As shown, an extruded tube 4, internally supplied with air, is initially cooled in a liquid bath 7 and is then engaged by clamps 12, 13 on endless chain pairs 14, 15 and 17, 18 respectively, before passing to a heating and expansion zone and subsequent cooling zone within a chamber 24. Chamber 24 comprises a tubular sizing member, preferably perforated and preferably having a continuous belt passing therethrough which forms a sheath around the tubing. The upstream portion of the sizing member is enclosed in a hot air bath or is subjected to steam or radiant heating and expansion of the tubing may be assisted by applying a vacuum. The downstream portion is cooled, e.g. with water or brine, with or without the application of a vacuum. Pressures within the tubing are further controlled by plates 9 adjustable towards and away from each other, and draw-off rollers 25. Chain pairs 14, 15 and 17, 18 are adjustable transversely of the tubing by rotation of screw 23, see also Fig. 2 (not reproduced). In modifications, liquid bath 7 may be replaced by air cooling means, plates 9 may be replaced by rollers, and rollers 25 by caterpillar tracks. Clamps 12, 13 may be of rubber or felt, the sizing member belt of P.T.F.E.-coated fibre glass and the tubing may be of P.V.C.

Abstract: 1,048,180. Stapling machines. R. A. NELSON. Oct. 5, 1965, No. 42252/65. Heading B4C. An apparatus for stapling a workpiece, such as a signature sheet S, while momentarily stopped in transit comprises a carriage 10, 14 for conveying the workpiece, a stop 12 for momentarily arresting the travel of the workpiece, and power-operated stapling and anvil means 20, 22 controlled by a trip switch 34, 32 located in the path of the workpiece so that it is actuated to bring about the operation of the stapling means simultaneously with the momentary arrest of the workpiece. The stapling means 20 includes a driver 42 actuated by a solenoid 48 and adapted to drive staples mounted in a magazine 35, Fig. 3 (not shown). The anvil means 22 is provided with an anvil 23 actuated by a solenoid 48; a pair of stapling and anvil means are adjustably mounted on across bars 18. In operation, a folded signature sheet S is fed from the rolls R of a folding' machine on to the rollers 14 of the carriage, the sheet being carried thereby until its leading edge abuts the switch 34 thereby energizing the solenoids so that staples are driven into the signature sheet. After a certain delay determined by the switch, the solenoids are deenergized so that the sheet is free to be fed by rollers 52, Fig. 1 (not shown), to a further folding machine.

[Also n Group XXII] In the manufacture of oil-filled electric cables, the core or cores are first evacuated and dried, a sheath is then applied by extrusion and the core or cores are impregnated, all these steps being performed under vacuum. A lead-sheathed core 3 leaving an extrusion die 4 passes through a first vacuum chamber 9 and then through a seal 8 into a second vacuum chamber 10 where the sheath is cooled by a water spray 13. The chambers are evacuated by connections 11, 12 to a steam-jet ejector. An outer seal 6 closes the chamber 10 and a seal 5 is provided against the extrusion press 1. Upon leaving the chamber 10 the cable core is impregnated whilst the vacuum still exists between the core and sheath, a valved plug having been fitted to each end of the cable.

Abstract: 1345854 Marine outboard motors MONARKCRESCENT AB 20 Sept 1972 [20 Sept 1971] 43582/72 Heading B7V [Also in Division F1] The engine exhaust pipe 3 of an outboard motor discharges under water and is surrounded by a thermally insulating air jacket 6 and a vibration damping water jacket 7. Cooling of the exhaust pipe by the water jacket is thus avoided so that after-burning can occur. Afterburning may be further encouraged by passing air from the jacket 6 through perforations into the exhaust pipe. Water is drawn into the jacket 7 through an opening 8 and overflows through an opening 9.
