Inventor: WALTON JAMES RIGNELL
IPC: B66C13/26
Filed: 1953-02-26
Abstract: 794,892. Control of A.C. motors. ELECTRICAL APPARATUS CO., Ltd. May 21, 1954 [Feb. 26, 1953], No. 5356/53. Class 38 (3). When an induction motor 1 accelerates from rest and the voltage across its slip-rings decreases, the potential difference developed across resistor 32 by means of rectifier 26 falls below the value of a constant potential difference derived from a rectifier 23. Upon the resultant current passing through relay coils D, E and resistor 32 reaching a predetermined value, the relay E is actuated to energize relay B and remove section 12 of the rotor resistance. As the speed of the motor further increases, relay D is actuated to energize relay C and remove the remaining section 13 of the rotor resistance, the relays D, E being slugged to prevent actuation due to transient effects. In addition to their use for starting the motor, the relays D, E may be adapted to regulate the rotor resistance in accordance with load, so as to increase the resistance when the load is light and to decrease it when the load is heavy.

Title: Improvements relating to friction brakes
IPC: F16D65/54
Filed: 1942-04-22
Abstract: 556,861. Adjusting brakes. ROVER CO., Ltd., and IVERSEN, P. A., SCOTT-. April 22, 1942, No. 5401. [Class 103 (i)] Stop devices for automatically maintaining the normal relative position of the cooperating friction elements of brakes having regard to wear of the elements are arranged to operate by non-elastic deformation of the material of which the stop is made. The stop device may, in addition, be capable of a small amount of elastic deformation so as to serve also as a release spring. A combined stop device and release spring is shown comprising a coiled length of wire g made for example,, of copper; aluminium, zinc, lead, or an ally thereof, attached at its middle part to a fixed part of the brake and at its ends to the brake shoes c. When during an application, wear occurs, the wire g is stretched beyond its elastic limit and the shoes are thus returned a constant distance in release. For the coiled wire there may be substituted a straight length or arc-shaped length or a pin of similar material may extend from each shoe to the anchor plate b so that it is bent laterally. Alternatively, the stop may be made of material of negligible elasticity and be arranged to engage the shoe by a slot that determines the normal clearance between the shoe and the drum, a separate release spring being provided. The invention may be applied also to brakes of the kind in which the brake drum and shoes are in constant contact and in which the braking effect is obtained by varying the pressure between the braking surfaces. The stops may also serve as lateral steady rests for the shoes.

Abstract: 1447564 Insulator assembly CIBA-GEIGY AG 6 Feb 1974 [6 Feb 1973] 05545/74 Heading H2C A h.v. insulator assembly, comprises an insulator having a glass-fibre reinforced plastics core 22 encased along one portion by a skirted insulated covering 23 and a pivotable mounting G above the covering connecting the insulator to a mast 1, the pivot axis 14 making an angle # greater than 30 degrees with the longitudinal axis L of the core. The core portion nearest the mast is retained in a metal sleeve 29 by two rings 7 made of a high strength sealing compound or a loaded bonding agent, the remaining space being filled with a soft sealing compound 8. The sleeve 29 is connected at one end to a socket 21 forming part of the pivotable mounting and adapted to receive a pivot pin 20 rigidly secured to a mast 1. The end of the pin 20 which extends into the socket 21 is part-conical and has two cylindrical parts 18 of white metal alloy which are spaced apart along the axis of the core. A castellated nut 26 which is covered by a cap 19 holds the pin in the socket 21. The sleeve 29 has beads 27 at the junction 28 with the resilient casing 23, to which it is stuck. The remainder of the space is filled with a finepored foam 30. The other end of the core 22 has a cap 25 with a bead 31 that engages the casing 23, the remaining space again being filled with foam 30. The tags 32 with bores 33 serve to secure clamping means for the conductor (not shown). The core has rounded edges and two parallel flat sides the widths of which decrease towards the skirted insulated end, whereas the radius and a length of the rounded edges are constant. Thus the thickness of the core between the parallel sides is constant and its cross-section becomes nearly circular near the conductor end. In another embodiment shown in Fig. 2 the thick end of a conical core 34 is anchored by two metal rings 35a and 35b spaced apart by a metal sleeve 35, the end face of ring 35b being closed by a cover. The pivot pins 40, secured to a small crossarm 38 define the horizontal pivot axis 14. Bearing sockets 41 which receive the pins 40 are rigidly connected via members 42 to a fork-shaped coupling device 43 which together form a pivotable mounting 44, releasably connected to rings 35a and 35b. Ring 35b is welded to a tag 45 which extends into the fork of 43 and held by pin 46. A stirrup shaped member 47 has its forked ends secured to links or tags (48) which are secured to ring 35a. In the case of large insulators the case 34 is, e.g. laminated with the interfaces of the glassfibre reinforced panels parallel to the plane of Fig. 2 and these panels may be interposed by panels of re-inforced high-strength organic plastics.

Title: Improvements in or relating to automatic or semi-automatic telephone systems
IPC: H04Q3/42
Filed: 1927-03-02
Abstract: 289,992. Coventry Automatic Telephones, Ltd., and Wilman, C. W. March 2, 1927. Attioinatic and semi-automatic exchange systews.- In a telephone system comprising codetranslating register-controllers, the translation is controlled by a common machine, which comprises a series of rotating drums 105, Fig. 2, each individual to a particular exchange, one of which is selected by a single wiper 8 in accordance with the setting of the office-register, so that by means of cross-connection to the wipers of a digit drum 101 the routing digits sent by loop-impulse springs 120 operated by the common machine, are controlled in turn over a single lead 110 multipled to the office-register bank-contact. The order in which the brushes of the drum 105 control the routing digits is governed by a circuit of a control switch over a number of leads 106 - - 109 in turn to a second drum 104 rotating in phase with drum 105. The drums 104, 105 rotate once while the digit wipers pas over a segment 121 - - 124 on the digit drum. Operation. When the register-controller is seized, relays 9, 10 energize, and the next code digit is repeated to vertical magnet 5 of the office register. Relay 11 operates in series with 5 and energizes magnet 16. At the end of the digit, between the release of relays 11, 16, magnet 23 of the digit distribtuor switch RS is impulsed, and the next digit is sent over its second contacts to rotary magnet 6 of the register, the wiper 8 selecting contact 30. When wiper 25 steps to its third contact, relay 12 is impulsed over common lead 35, wiper 103 and earthed segment 102 of the digit drum, and operates the control switch magnet 17, so that a circuit [battery, drum 104, lead 106, wiper 20, 37, relay 13, 38, 8, 30, 110, 105, 111, 115, 119, earth] will be momentarily formed to energize relay 13, which then locks in series with relay 15. Short-circuiting contacts 42 are opened so that impulses are sent out over the loop 3, 4, until after four impulses wiper 115 engages segment 121 when relay 14 is operated and locked to short spring 120 at 43. When wiper 103 again engages segment 102, relay 12 is impulsed to step on switch TS and release relays 13, 14, 15, springs 120 remaining short-circuited. The next digit is controlled over leads 107, 110, 112, and wiper 116 of the digit drum, 6 impulses being sent, and two more digits 2, 8, are sent under control of wipers 113, 114. If less than four routing digits are required cross-connection may be omitted. The numerical digits are now sent by connections not shown over the digit registers and the digit-drum wipers direct. When all digits are sent, wiper 19 breaks the circuit of relay 10, connecting earth at 49 to release magnets 7, 18, 24 to return the controller to normal. The invention is applicable to a controller having a relay register set.

Abstract: 586,913. Gas turbines. TURBO ENGINEERING CORPORATION. April 15, 1943, Nos. 6078 and 6079. Convention dates, April 18, 1942, and May 9, 1942. [Class 110 (iii)] In a gas turbine plant, the high-pressure turbine drives the compressor and the lowpressure turbine provides the useful power at an output shaft or in the form of a propulsion jet for aircraft. The plant is governed by automatic maintenance of a specified combustion temperature and means, such as angularly-adjustable inlet vanes, for controlling the flow of gases to the low-pressure turbine and consequently varying the back-pressure of the first turbine. Air from a four-stage compressor, with an interstage cooler, delivered at 2, is burned in a combustion chamber 4 and the products of combustion pass to a two-stage high-pressure turbine 12. Flow in the bladings 10 is mainly radially inwards and in the blades 20, axial. The low-pressure turbine 80, of similar construction, drives a power shaft 96 and may be designed to provide an exhaust with a high axial velocity and no swirl for use in jet-propulsion. The nozzle passages for the pladings 78 are defined by angularly adjustable vanes 76 which are all coupled to an actuating ring 118, Fig. 4, which is rotated through a small arc by a control lever 132. In another form, the high-pressure turbine comprises contra-rotational rotors 226, 208, Fig. 6, the latter driving an initial compressor stage 202 and the former, the three later stages 218, 220, 222. The low-pressure turbine has a single stage 262 with angularly adjustable inlet vanes 256 and discharges through a heat-exchanger 260 in which the compressed air is heated. The turbine 262 can be reversed by closing valve 280 and opening valve 278 which admits gas to backwardly directed nozzles 276 and cause it to impinge on the end parts of the turbine blades. Fuel is supplied by a pump 284 through a pressure-regulating valve 288 and a throttle valve 294 controlled by a thermostat 298, 296. The plant may be started by air provided by another power pump and admitted to the inlet of the compressor stage 202. Specification 520,045 is referred to.
