Title: Improvements in the manufacture of metal tubing for use in the manufacture of electric cables
Inventor: MAYSMOR CHARLES WILLIAM KINSEY
IPC: H01B13/26
Filed: 1954-10-25
Abstract: 774,600. Making tubular electrical conductors. BRITISH INSULATED CALLENDERS CABLES, Ltd. Oct. 24, 1955 [Oct. 25, 1954], No. 30716/54. Addition to 703,003. Classes 83 (2) and 83 (4). Winding and reeling; drawing; soldering.-In a modification or improvement of the method of making a metal tube, e.g. a tubular electrical conductor as disclosed in the parent Specification, the outer tape which is to be applied to the transversely bent inner tape, is a tape prepared for soldering thereto by depositing on one of its surfaces at least two longitudinally extending coatings of solder metal covering strips of that surface, and by forming on the coatings a dry film or films of flux covering the coatings and wherein the prepared outer tape is thereafter applied to the transversely bent inner tape with the prepared surface facing the inner tape and is soldered to the inner tape along the flux-covered strip coatings of solder metal. Apparatus for carrying out the method comprises a drum 1 on which is coiled a copper tape 2 which is drawn from the drum and over three curved spaced plates 4, 5 and 6 maintained at different temperatures. The plate 4 is heated to 300‹ C. and first flux from a container 8 is applied to the tape and then four strips 12 (Fig. 3) of solder metal are applied from four reels 13 carrying solder wire which is fed to the tape by rubber feed rollers 15. The plate 5 is unheated to cool and solidify the solder metal. Towards the end of plate 5 a film of quick-drying flux 52 is applied over the solder strips from a vessel 22. Plate 6 is heated to a temperature between 175‹ and 200‹ C. The coated and fluxed tape passes under a guide roller 24 and through haul-off rollers 25 on to a driven take-up drum 28 via a guide roller 26 mounted on a pivoted, weighted lever 29. A cam 31 on the lever operates an hydraulic device 35 for controlling the speed of the drum 28. The edges 54 of the tape are left unfluxed to facilitate the removal of beads of solder formed during the soldering together of the two tapes. Also an unfluxed or uncoated longitudinal strip 37 may be left down the centre of the tape to reduce the risk of flux entering the tube formed by the inner tape. In making the composite tube a tape 39 (Fig. 2) is bent into tubular form by a forming die 44 after passing-through a cleaning solution in a container 41 and an edge corrugating device 43. The coated tape 2 is drawn from a drum 45 through rollers 49 which commence shaping the tape and through die plates 50 which progressively transversely bend the tape around the inner tape 39. Finally the two tapes are soldered together by heating and cooling devices in apparatus 51.

Title: Improvements in and relating to liquid dispensing apparatus
Inventor: PHILLIPS HUGH EDMUND
IPC: B67D7/16
Filed: 1953-11-09
Abstract: 779,736. Delivering liquid fuel. BECK & CO. (METERS), Ltd. Feb. 9, 1955 [Nov. 9, 1953], No. 30992/53. Class 116. The pump motor of a petrol pump is switched off, after delivery of a pre-set volume, by a trip mechanism controlled by mechanism closing the delivery valve but offering no resistance to that mechanism. In the construction illustrated a partial closure of the valve to provide a dribble feed is effected when a disc 14 rotated to pre-set the volume to be delivered has almost been returned to its initial position by the liquid meter so that a roller 42 can enter a notch 15 in the disc to permit a link 20 suspended from a lever 18 pivoted at 19 to fall and so turn a bell-crank 22 connected by a link 24 to the valve. Complete closure of the valve is prevented by engagement of a spring biased pawl 181 carried by an arm 180 rigid with the lever 18 with a step 183 on a cam 182 which is geared to rotate in the opposite direction from the disc 14 so that it terminates the dribble feed when the step 183 leaves the pawl 181. The switch controlling the pump motor is initially closed by depressing a link 28 which carries a stop 40 engaging one arm of a spring biased bell-crank 30 connected by a link 34 to turn a lever 36 so that a spring biased latch 38 on it engages a tooth 50 fast with the bellcrank 22. The final movement of the bellcrank 22 to terminate the dribble feed permits the lever 36 to swing so that the pawl 38 engages a fixed abutment 56 which disengages it from the tooth 52 so that the spring 32 biasing the bell-crank 30 may return the linkage 30, 34, 36 to its initial position and so raise the link 28 to open the switch to the pump motor. In an alternative construction shown schematically in the Specification no dribble feed is provided and minor alterations are made to the link-works.

Title: Improvements relating to alternating current electric motors
IPC: H02K17/36
Filed: 1935-11-09
Abstract: 465,729. Control of two induction motors. WALSH, A., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Nov. 9, 1935, No. 31077. [Class 38 (iii)] [Also in Group XXXV] A driving arrangement for elevators, hoists, and like apparatus, comprises a three-phase high-speed slip-ring induction motor 2, and, mechanically coupled thereto, a polyphase lowspeed induction motor 3, the stator of the motor 3 being accommodated in slots numbering less than three times the number of poles for which the winding is connected. The low-speed motor may have a stator arranged as a two-phase winding connected to the source 6 for the motor 2 through a Scott connected transformer 10. For high speeds, a switch 7 is thrown to the left to energize the motor 2, and for low-speeds the switch 7 is thrown to the right to energize the motor 3. In an alternative arrangement in which'the stator of the motor 3 is two-phase, one phase of the winding is connected with a mid-point on the other phase winding, the threephase supply being connected to the free ends of the windings. In another arrangement, the motor 3 has a three-phase stator winding comprising for each pair of poles three conductors located in respective slots and energized consecutively in the same sense from the three phases of the supply for the motor 2. These conductors may be connected at one end of the stator to an energizing circuit giving a current phase relationship of 120‹ between adjacent conductors, a return circuit or circuits being disposed outside the effective part of the stator core. Alternatively, the return circuits for the conductors may be effected through further slot conductors each located in the slot accommodating a conductor of the next phase, and in a further embodiment the stator of the motor is divided into zones in each of which the winding is arranged with three conductors per pair of poles located in respective slots and energized with currents having a phase relationship of 120‹ between adjacent conductors, the phase sequence within a zone being the same for all zones but the current reversed from zone to zone. In this embodiment, conductors may be omitted, and the stator core cut back at those points where the change in the current direction is made. Where the conductors are arranged to be fed from a circuit giving a current phase relationship of 120‹ between adjacent conductors, the conductors may be fed through a transformer having three core rings coaxial with the stator. With a 60 pole stator winding, for example, the core rings may be hexagonal, and provided with five single turn secondary windings on each straight limb.

[Class 38 (ii)] A current conversion unit for wireless apparatus or the like adaptable to work on either of two supply voltages, e.g. 6 or 12 volts as used in automobile electrical systems, comprises a transformer A, Fig. 1, having a primary winding tapped for the alternative voltages, a vibrator holder B, Fig. 1, having sockets, connected to the transformer tappings, secondary contacts when used, the electricity supply and the valve heaters, for making contact with pins on a vibrator base E, Figs. 2, 3, and a vibrator so connected with the base that when the vibrator is inserted in the holder in one position, Fig. 2, the valve heaters or groups of heaters C, D are connected in series and the vibrator driving coil is connected through a resistance P to a higher voltage tapping 12v on the transformer and when the vibrator is inserted in the holder in a position in which it has been turned through 180 degrees, Fig. 3, the valve heaters or groups of heaters are connected in parallel and the driving coil is connected directly to a lower voltage tapping 6v on the transformer. The arrangement of connections will depend upon whether the vibrator is of the synchronous or non-synchronous, shunt driven or separately driven type, a rectifier G being necessary with the non-synchronous type. To avoid the necessity of winding the low voltage section. of the transformer primary winding of heavier gauge wire than the high voltage section, the winding may be wound in four equal sections of the same gauge wire, all the sections being in series for high voltage operation and pairs of sections in parallel for low voltage operation. Also the most neutral turns, i.e. those near the centre tapping CT may be arranged to form the outer layers of the winding, thus forming an electrostatic screen dispensing with the necessity of a separate screen; the same principle may also be applied to the secondary winding. Specification 588,317 is referred to.
