Title: Improvements in and relating to Electrical Insulation
Inventor: TURNBULL ROBERT BOLTON
IPC: H02K3/34
Filed: 1966-07-07
Abstract: 1,169,193. Insulating coating. MICANITE & INSULATORS CO. Ltd. 29 June, 1967 [7 July, 1966], No. 30578/66. Heading B2E. [Also in Division B5] Insulation tape incorporates a heat-shrinkable plastics material giving the tape a heat shrinkable characteristic at least in the lengthwise direction of the tape and a curable synthetic bonding resin in a set but not fully cured condition, the shrinkable material having the property of shrinking at a curing temperature for the bonding resin. After the tape has been wrapped onto say a stator coil, it can be heated to cause shrinking of the tape and bonding together of overlapping turns thereof by the bonding resin. Mica in the form of mica flakes, splittings, or in the form of mica paper may be bonded to the heat-shrinkable material by the bonding resin. Shrinkable material can be in the form of a perforate or imperforate film or in the form of a fabric, e.g. a fabric woven entirely from filamentary heat-shrinkable plastics material, or from such material as warp with glass as wept, a paper with or without reinforcing strands. Suitable heat shrinkable materials mentioned are radiation-modified polyvinyl chloride, vinyl copolymers with vinylidene chloride or vinyl acetate, radiation-modified polyolefines such as polyethylene and polypropylene and radiation-modified neoprene. Heat-shrinkable polyester resin such as polyethylene terephthalate is preferred. The bonding resin may be epoxy resin. To prevent excessive shrinkage the heat-shrinkable material may be initially in a partially heat-set or heat-stabilised condition. Several tape-making procedures are illustrated. In Figure 4 mica splittings 8 are laid in overlapping relation onto a paper web and a web of heatshrinkable fabric 9 is brought into contact with the mica-carrying web at a roller 11. The fabric 9 is impregnated with epoxy rsein applied in fluid form by drip-feed from trough 12. The composite is passed through a heated oven 13 and the paper web 5 is separated. In other procedures a mica paper web and a heat-shrinkable web are fed together round a roller in a bath containing epoxy resin in a fluid form and the composite passed through a heated oven (Figure 5 not shown); a heatshrinkable web is fed over a roller dipping into epoxy resin in fluid form and then passes through a heat oven before feeding through pinch rollers along with a web of mica paper, one of the pinch rolls being heated sufficiently to cause the epoxy resin to flow and permeate the mica paper (Figure 6 not shown).

Filed: 1950-12-21
Abstract: 705,594. Control of A.C. motors. CLARKE, CHAPMAN & CO., Ltd March 20, 1952 [Dec. 21, 1950], No. 31150/50. Class 38(3) The stator windings 20, 21, 22, of a squirrel cage induction motor driving a winch are changed from delta to star connection to limit the stator current when the motor is stalled by the application of a foot-operated brake. The stator windings are initially connected in delta due to closure of contacts 25, 26, 27, controlled by relay coil 70 which is energized through rectifier 51-54. When the brake pedal is operated to stall the motor, contacts 10 are closed to energize timer coil 61 which, after an interval, opens contact 63 and closes contact 64. The delta contactor is thus opened, and the star contactor which has coil 75 and contacts 23, 24, is closed, thereby reducing the motor current. When the brake pedal is fully released the return to the delta connection is effected without delay. Inching operation is provided by partial release of the brake, the motor windings being connected in star.

Title: Apparatus for supplying the d.c. windings of a synchronous motor
IPC: H02K19/12
Filed: 1952-12-09
Abstract: 728,777. Control of A.C. motors. HACKBRIDGE & HEWITTIC ELECTRIC CO., Ltd., and WELLS, R. Oct. 29, 1953 [Dec. 9, 1952], No. 31157/52. Addition to 690,964. Class 38 (3). Relates to a modified form of the apparatus described in the parent Specification for supplying the D.C. windings of a synchronous motor 10, wherein an alternator 16 is driven by the motor and supplies the D.C. windings through a gridcontrolled rectifier 18. As shown, the motor is of the salient pole type and has its stator windings energized from a three phase source 11, whilst its rotor windings are connected to slip-rings 12a, 12b. For starting, change-over switches 13, 21, are moved to the right-hand positions so that resistor 14 is connected across the rotor of the motor 10 which thus accelerates to near synchronous speed as a squirrel cage induction motor. Grids 20a-20c of the rectifier 18 are connected to their associated anodes 19a-19c, the rectifier being free-firing during the starting operation. Upon approaching synchronous speed, the switch 13 is first moved to the left-hand position so disconnecting resistor 14 and connecting the sliprings 12a, 12b, to the D.C. supply provided by alternator 16 and rectifier 18. The motor pulls into synchronism with the rectifier still in the free-firing condition. The switch 21 is then changed over so that the grids 20a-20c are connected to the supply 11 through a phase shifter 23 for automatic control as described in the parent Specification. The anodes 19d-19f of the rectifier have no associated grids, thus ensuring a minimum rectifier output under all circuit conditions, unaffected by the delay angle of the anodes 19a- 19c. Since the switch 21 is of the make-before break type the grids are not de-energized during operating of the motor, resistors 22, 24, being provided in view of the linking of the two grid supply systems during change-over. The field windings of the alternator are connected to slip-rings 17a, 17b, in parallel with the rotor windings of the motor so that the alternator is self-excited. This arrangement allows the alternator excitation to increase with the load on the motor, an overcompounded characteristic being obtainable. The alternator field winding, if of low voltage rating, may be connected to a variable series resistor; alternatively, the rotor winding of the motor is connected in series with the alternator field winding and a diverter resistance shunted across the winding requiring the lower current. The synchronous motor may be of the non-salient pole type, Fig. 2, (not shown), the rotor winding then having three slip-rings which are connected to star-connected variable resistors for starting. In the running position, these resistors are connected to the cathode of the rectifier.

Abstract: 683,031. Viscosimeters. TEXACO DEVELOPMENT CORPORATION. Dec. 7, 1949, No. 31394/49. Class 40 (i) [Also in Group XIX] A viscosimeter comprises a body 14, Fig. 1, rotated at constant speed in the fluid 16, the container of which is rotatable in relation to its support against a spring 21. The support, which in this embodiment is a graduated table is acted on by a reversible servomotor to keep the tension of the spring equal and opposite to the torque due to the rotation of 14. The position of the container in relation to the fixed framework thus remains substantially constant and the position of the support indicates the viscosity. In modifications, Figs. 2 and 4 (not shown) servo-driven supports operate recording pens directly and via a selsyn link respectively. In a further modification, Fig. 5, the relays 111, 112 controlling the servo-motor 119. instead of being energized directly from a pair of switches as in the arrangements previously described, are operated via a phase-sensitive rectifier and D.C. amplifiers from the output of an A.C. bridge which is unbalanced by movements of copper discs 93, 94 in relation to inductors 96, 95 when the fluid container moves in relation to its support.
