Title: Improvements relating to machines having induction motor drives
Inventor: HOLT FREDERICK BRERETON
IPC: H02P25/20
Filed: 1952-11-20
Abstract: 741,141. Control of A.C. motors. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Oct. 28, 1953 [Nov. 20, 1952], No. 29373/52. Class 38(3) A driving arrangement for a spinning frame comprises two induction machines M1, M2, coupled permanently with the frame to drive it respectively at different speeds. As shown, closure of a "start" contact GC causes one or other of the main contactor coils C1, C2, to be energized, depending on the position of selector switch S. Assuming the contactor Cl to be thus selected, the machine M1 is connected to the three-phase supply through contacts MC1, thereby becoming the driving motor, and auxiliary contacts AC1 are opened to disconnect the motor from rectifier R.' A time delay relay T is also energized to close contacts T1 so that direct-current is applied to the braking machine M2 through contacts AC2 of contactor C2. A, voltage regulator VR is, at this stage, in the position corresponding to maximum output so that the machine M2 exerts its full braking torque, the frame being accelerated by moving the regulator towards its minimum voltage position wherein contacts RC are closed to energize a coil HOC for holding the regulator in the minimum position. When the frame is operating at full speed, or other predetermined speed, the supply of direct-current to the braking machine is interrupted. The drive may be changed from the machine M1 to the machine M2 by means of the selector switch S. When "stop" switch SC is opened the driving motor is disconnected from the alternating-current supply, and both machines are connected to the rectifier R for braking action on the frame. The regulator VR returns to the position corresponding to maximum voltage, and the direct-current supply is disconnected by the opening of the contacts Tl after the frame has come to a standstill. If the lower rate of deceleration is required, the alternating current supply may be left connected to the driving motor whilst direct-current is applied simultaneously to the braking machine, the alternating-current being removed when the speed of the frame has reached a low value. The regulator may be operated by a controller similar to that described in Specification 689,323. In a modification, the machines M1, M2, are replaced by a single squirrel cage induction machine having multiple wound stator windings acting respectively as driving and braking windings. In another arrangement the machine has a single pole-changing winding and direct-current is applied to a set of terminals not at the time supplied with alternating-current whereby to provide a braking-action on the equipment.

Title: Improvements relating to systems of illumination employing electric non-filament gas tubes
IPC: H05B41/44
Filed: 1931-10-23
Abstract: 394,718. Supply systems for vacuum &c. lamps. WATSON, A. C., West View, Marietta, Ohio, U.S.A. Oct. 23, 1931, No. 29429. [Class 38 (iv).] Varying visual effects such as changing patterns, letters, words, or symbols with or without colour changes are obtained by apparatus comprising one or more electric non- filament gas tubes, such as neon tubes, and a moving mask or masks apertured with suitable patterns &c. The tube or tubes are illuminated intermittently or in sequence ; in the first case they are moved and in the second the effect of movement is produced and the speed of movement of the mask is different from that of the movement or apparent motion of the light whereby the changes in pattern are produced. Colour effects are introduced by the use of neon and mercury tubes. The invention is not restricted to circular motion. A stationary tube may be used with a secondary moving mask to give the effect of movement of the light. Brilliancy may be increased by arranging that the light at a given point is produced by the overlap of at least two consecutive illuminations of or from a tube, which recur within the critical frequency for continuous vision. Fig. 4 shows stationary sources of light 15 each illuminating a sector of a disc and comprising a neon tube in series with the secondary of an induction coil, a condenser and a contact on a timing commutator. Synchronously rotated with the commutator is an interrupter disc which breaks the circuit of the primary winding of the induction coil. The mask 21 is driven at a speed different from the timer. Fig. 7 shows an arrangement with a single source 40 and a secondary mask 44 behind the main mask 42.

Title: Improvements in or relating to sheet materials
IPC: E04F13/08
Filed: 1965-07-12
Abstract: 1,138,353. Laminated tile assembly. G. B. E. SCHUELER. 4 July, 1966 [12 July, 1965; 16 Dec., 1965], Nos. 29471/65 and 53514/65. Heading B5N. A method for the production of sheet materials comprising grouted surface units 1 on a backing layer comprises positioning the surface units in the desired configuration or pattern with spaces between them to act as grout lines, applying a layer of an adhesive material 3 to the backs of the surface units, and pressing part of the adhesive material into the grout lines while allowing the remainder to form a continuous adhesive backing layer. The sheet material may also include a support layer 4. As described the surface units 1 are ceramic natural or plastic tiles or mosaic units, the adhesive is thermosetting or thermoplastic, natural or synthetic, and is for example an epoxy, acrylic, alkyd, coumarone, polyester, polystyrene, phenol-aldehyde, or amino-aldehyde resin, e.g. polyvinyl acetate. The support layer 4 may be rigid e.g. of chipboard, asbestos, plastics sheeting or reinforced concrete, or flexible e.g. of rubber sheeting. In one embodiment the surface units are removably adhered to a temporary support, e.g. an endless paper belt, and liquid adhesive is applied diagonally from a hopper, excess adhesive being removed by a wiper. Pressure is applied to the liquid adhesive by a source of pressurized air in the hopper. A support layer may be applied to the surface units before or after the temporary support is removed, and is bonded to the units by use of a hot or cold press or rollers. The surface units may be surrounded by a mould whilst the adhesive sets. In an alternative embodiment the adhesive is applied to the surface units as a blanket having a dough-like consistency, and may be pressed into the grout lines by a removable regenerated cellulose sheet, The adhesive, which may include fibres, e.g. of glass or sisal and fillers, e.g. calcium carbonate, may be formed into a blanket by sheeting, calendering, or extrusion, and may be hardened by heat and/or pressure. If the adhesive is not to fill the grout lines completely the surface units are arranged on an elastic, e.g. rubber, support whilst the pressure is applied which forces the adhesive into the grout lines. Alternatively the grout lines are part-filled with powder, or a water-soluble compound. The units and/or adhesive may be coloured. The adhesive or support may include means, e.g. hooks, for attaching the sheet material to a support, e.g. a wall. The sheet materials may be provided with grooves or slots, or other interlocking devices at their edges. The sheet materials may be of a shape other than plane, e.g. semi-cylindrical.

Title: Protective apparatus for electrical distribution networks
IPC: H02H3/06
Filed: 1939-11-16
Abstract: 538,864. Protective cut-out systems. MASCHINENFABRIK OERLIKON. Nov. 16, 1939. No. 30212. Convention date, Nov. 17, 1938. [Class 38 (v)] A network is protected by a system which combines .the advantages of instantaneous tripping and reconnecting, with the consequent minimum of disturbance by transient faults, and selective protection which localizes the effects of faults of a more permanent nature, by operating with a time-delay depending on the magnitude of the current or voltage or circuit-constants, such as impedance. On overload, a circuit-breaker is tripped instantaneously and at once reclosed, and if the fault persists, further selectively-retarded trippings and resettings occur, the first operation being so rapid that the selective relays do not have time to operate. A single relay may be employed for both actions but, as shown, separate relays g, g<1> are provided, the latter being instantaneous and responsive to current, voltage or impedance. When energized, g<1> makes the circuit of the trip coil c and of one coil of a slow-release relay r over the contact a which is closed and opened with the main switch (not shown). The latter opens and an auxiliary contact thereof d closes and energizes over contacts of relay r a second coil of that relay and a coil p which operates contacts z or the closing valve of a motor, magnet, or compressed-air cylinder b for closing the main switch. Coil p also makes, over auxiliary contacts p<2>, p', respectively, a holding circuit for itself and an energizing circuit for a coil q which opens at q<3>, q<2>, respectively, the original energizing circuits of c, p and makes a further holding circuit for itself at q'. Hence, when d reopens, due to reclosure of the main switch, q remains energized and p is deenergized; r is also de - enerigized but remains lifted until its time-lag expires. If, therefore, on reclosure, the fault persists, reclosure of contacts g' is ineffective to make the circuit of trip coil c, this circuit being however made by the retarded operation of the selective relay g. When the main switch again opens and d closes, the circuit of reclosing coil p cannot be made until r falls back and de-energizes q. Further retarded reclosings can be effected by operating contacts in parallel to those of relay r by means of an adjustable time relay in dependence on relay g, the subsequent trippings, if any, being subject also to relay g. A change-over control switch h comprises contacts 7, 8 in the trip circuit and a contact 2 which can be changed over so as to be depressed against either contact 1 or 3 for, respectively, manual closure and manual tripping not followed by automatic reclosure. Only switches connected to actual or potential sources of energy need be equipped with automatic resetting apparatus.. By placing a voltage or phase-measuring relay in the circuit of the reconnecting relays of all except one of the circuit-breakers, reconnection of those circuitbreakers may be made dependent on voltagephase conditions, while the one breaker recloses instantly.
