Filed: 1947-05-27
Abstract: 623,908. Electromagnetic ammeters. GENERAL ELECTRIC CO., Ltd., and FRIEDLANDER, E. S. May 27, 1947, No. 14077. [Class 37] [Also in Groups XXXV and XXXVII] An electromagnetic relay or indicating device has a rotary armature 2 which moves one way or the other under the differential action of two pairs of poles 8, 10 and 9., 11, each pair being excited by a winding or (as shown) by two windings connected in series or parallel. As shown, the polepieces are cylindrical, but small deviations from the cylindrical may be used to introduce a centralizing torque or for other effects. With A.C. in order that the effects of the two opposing currents will always balance when the ampere turns of their windings are equal, the currents must normally be in phase. However, if equality of phase cannot be achieved, two of the above devices may be mechanically coupled and currents supplied to them that differ by 90 degrees from each other. Alternatively, the four coils of one device may be connected in pairs to form two systems 90 degrees phase-displaced from each other.

Title: Improvements in and relating to automatic switching arrangements for balancing equipment
IPC: H02J1/08
Filed: 1930-05-12
Abstract: 352,158. Balancing. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Bany, H. ; 904, Myra Avenue, and Lockett, H. E. ; 528, Laurel Road, both in Yeadon, Pennsylvania, U.S.A.) May 12, 1930, No. 14576. Convention date, May 10, 1929. [Class 38 (iv).] Automatic regulation.-A balancer set 1, as shown in the Figure, for connecting to a 3-wire system comprises two similar machines 2, 3, with the armatures connected in series and the fields 10, 11 connected in series with each other across the set terminals through a common resistance 12. On the occurrence of "out of balance" in the system a voltage balance relay 18 closes a circuit for a time-delay relay 21 which, if the out-ofbalance condition persists, energizes a master relay 22. Auxiliary contacts on relay 22 elose the circuit of the operating coil 7 of the main conductor switch. The set then starts up and series resistances 24a, 24b in a starting device 23 are short-circuited in turn as the machine runs up. When the starting operation is completed auxiliary contacts 26 close and relay 15 is energized to connect the rheostat contact 14 to the neutral of the set. The relay 29, responsive to the voltages of the machines 2, 3, controls the rheostat motor 33 to equalize the voltages of the two machines. As the machines are similar the rheostat lever 14 is in the mid-way position when the voltages are equal and shortcircuits contacts 36 to energize the closing coil 37 of switch 9 and connect the neutral of the set to the neutral of the system. If the switch 9 is not closed within a predetermined time after relay 22 has operated a lock-out relay 44 opens its contacts 45 and breaks the retaining circuit of relay 22 and shuts down the set. If the neutral current falls below a predetermined value timedelay relay 39 is energized to de-energize relay 22 and shut the set down. Over-current relays 41, 42 in a similar manner shut the set down on the occurrence of a high current in either the main conductors 4, 5 and with the lock-out relay are arranged to be manually re-set.

Title: A heat and/or pressure sensitive record material unit
IPC: B41M5/28
Filed: 1965-04-07
Abstract: A heat and/or pressure sensitive material or unit comprising on or within a support, a liquid solution of a first solid compound encased with a pressure rupturable, vapour-permeable polymer and a second solid compound reactive with the first to produce a detectable mark and being vapourisable on heating, this second compound being on or within the support or on or within a sheet placed in contact with the support, the reaction occuring by either heating the material or unit imagewise or by applying pressure imagewise.  Normally, the solution of the first compound is encased in polymeric capsules which may be dispersed within a porous support or coated in the same layer or in a separate layer as the second compound on the support (which may be the porous or non-porous).  Alternatively, the two compounds are on separate sheets which may be stapled or adhesively joined, or on one sheet folded over, or on two sheets with one sheet inserted inside the fold of the other sheet.  Specified reactants are crystal violet lactone with a diazonium fluoborate or a 4, 4 isopropylidene phenol; benzoyl leuco methylene blue or 2, 5-dichloro-N-phenyl leucauramine with a diazmium fluoborate; cobalt naphthenate with ammonium sulphide; and copper oleate with dithioxamide; the first-named component being encapsulated.  Alternatively, crystal violet lactone may be paired with other phenols or diphenols or with carboxylic acids or crystal violet lactone may be replaced by other leuco dye bases.  If pressure is used to produce the image, the image is formed on the sheet with the first compound.

IPC: H01B7/04
Filed: 1948-06-02
Abstract: 641,922. Screened cables; couplings. LIVERPOOL ELECTRIC CABLE CO., Ltd. June 2, 1948, No. 14841. [Classes 36 and 38 (i)] A conductor a having rubber-like insulation b is provided with a flexible screen c of conducting rubber in which are embedded one or more metallic conductors d, each of which forms an open helix about the cable core. A multicore cable may have the individual cores screened in this manner, or they may be collectively screened as in Fig. 3. The insulated conductors a, b, and bare earth conductor g are assembled in a rubber-like cracore f, which may also be conductive, and then enclosed in the screen c, d, and an outer protective sheath e. The screening layer may be built up on the cable core by applying a lapped or extruded layer of conducting rubber, over which the metal conductors are wound and a further conducting rubber layer applied, the layers being bonded together by vulcanizing under pressure. Alternatively the screen may be preformed, either by laying the wires between sheets of conducting rubber and nailing the sheets by pressure, or by extruding a covering of conducting rubber around suitably spaced wires. This composite screen is applied to the cable core by lapping on. Such preformed screens may be cut into tapes and used for repairing damaged screens when required. Specification 526,895 is referred to.

Title: Improvements relating to the armouring or protection of structures subject to the attack of projectiles
IPC: F41H5/02
Filed: 1919-06-13
Abstract: 150,831. Eyncourt, Sir E. H. T. d', and Williamson, L. C. June 13, 1919. Armour.-Structures are protected against attack from armour-piercing and other projectiles by the provision of a number of bars or girders A spaced at such a distance apart that the point of an attacking projectile cannot impinge on the surface of the structure. The bars are of hardened or toughened steel or steel alloy, and of substantial cross-section. In a modification, the bars are made of such cross-section that they interlock, as shown in Fig. 4, the bars being such that the point of the projectile cannot impinge directly on the under bars. A covering armour-plate may be fitted over the upper surface of the bars, and may be at such a distance thai the point of any shell strikes the bars before the base of the shell has passed through the armour plate. Specification 4761/76 is referred to.

Title: Reluctance motor power circuit
IPC: H02P25/08
Filed: 1970-03-26
Abstract: 1,240,979. Control of A.C. motors; electric motors. FORD MOTOR CO. Ltd. (Ford Motor Co.). 26 March, 1970, No. 14975/70. Headings H2A and H2J. Each phase of a variable reluctance motor comprises a toroidal winding 20, 26, 30, surrounding a stator disc 38, 40, 42, having wedgeshaped sections 43 of laminated steel spaced by material having a low permeance. A rotor disc 50-52, 54-56 and 58-60 is positioned on each side of a stator disc and is constructed similarly to the stator disc. The periphery of each rotor disc is wound with a thin layer of low permeance material. The windings 20 and 30 are associated with L-shaped laminated steel stator members 16 and 28 while T-shaped members 22, 24 hold the three windings in place. The motor is coupled to a load such as a vehicle driving-wheel and has position and speed sensors. A controller, which is connected to a battery 90 and to the motor windings is adapted to receive signals representing a desired torque, a forward or reverse function, and a system protection input, Fig. 2 (not shown). The battery may be replaced by a generator driven by an engine or induction motor, or a rectifier may be used. S.C.R. 120 is fired, at low motoring speeds, when laminated sections 61 of rotor discs 50, 52, begin to move into alignment with laminated sections 43 of stator disc 38. Capacitor 122 charges and winding 20 is energized at a rate dependent upon the residual inductance of the battery and associated circuitry. As the current reaches its peak, S.C.R. 128 is fired to provide a freewheeling path for the winding-current, the capacitor completing its charging cycle. Then the S.C.R. 120 switches off and the energy stored in the capacitor 122 is returned to the battery through diode 124 and S.C.R. 128. When the freewheeling current in winding 20 decays to a predetermined value, the current is reinforced by triggering S.C.R. 120. The residual charge on capacitor 122 may be reversed by rectifier 130 and inductor 132 before triggering S.C.R. 120, so providing greater current reinforcement. As the laminated sections approach complete alignment, winding current is removed by omitting the gate pulse for S.C.R. 128 at the end of the reinforcing cycle. Thereupon the capacitor 122 discharges through the battery and winding 20. The freewheeling and reinforcing operations are omitted at higher motor speeds. The diode 124 may be replaced by S.C.R. 126 to increase the speed and power of the motor by building up the charge on capacitor 122 over a period before discharging it through the winding 20. As the laminated sections are moving out of alignment, the motor may be braked by firing S.C.R. 120 to produce reverse torque.

Title: Improvements in, or relating to, high frequency electric induction furnaces
IPC: H05B6/02
Filed: 1945-06-14
Abstract: 593,323. Heating metal rods automatically by electromagnetic induction. BIRLEC, Ltd., HARRIS, J., and SHIRLEY, G. H. June 14, 1945, No. 15066. [Class 39 (iii)] Induction heating of metal rods or the like in automatic succession is carried out in a multiple coil furnace 1. Heating coils 9 which may be six in number, are arranged below a magazine 2 divided into complementary compartments. The metal rods to be heated are fed via shoots to rockable pusher bars 37 positioned immediately below each shoot. The rods to be heated are transferred one at a time to a bolt feeding mechanism 10 associated with each heating coil 9 by the rockable pusher bars 37. The period of heating is determined by the interval between each loading cycle, the heated rod being displaced by the next rod entering the bolt feeding mechanism. The feeding mechanism is actuated by compressed air which is controlled by valves 8 actuated by a camshaft 6 driven by a motor 7 in the base of the machine. A discharge shoot receives each treated work piece when it is displaced from the feeding mechanism and in passing down the shoot the work piece interrupts a beam of light, falling on a photocell associated with suitable control circuits, whereby the power is cut off if the regular flow of work pieces from the machine is interrupted. The mechanism may be adjusted to feed various sizes and lengths of material to be heated.

Title: Improvements in or relating to protective systems for electrical equipment
Inventor: PEARSON EDGAR
IPC: H02H11/00
Filed: 1959-05-02
Abstract: 894,409. Protective arrangements. ASQUITH ELECTRICS (COLNE) Ltd. May 2, 1960 [May 2, 1959], No. 15075/59. Class 38 (5). A protective arrangement, e.g. for a portable tool, comprises an earth loop formed by two earth circuits, one circuit including the winding W1 of a first relay R1, a transformer secondary winding b1 and a winding W3 of a second relay R2, and the other circuit including a choke A, a transformer secondary winding b and a further winding W2 of the relay R2. Under normal conditions, current circulates in the earth loop and the windings W2, W3 oppose each other so that the contacts C2 of the relay R2 remain closed. The circulating current causes relay R1 to close its contacts C1 so that an operating circuit for the winding W4 of a third relay R3 is completed on the operation of a push-button switch PB. Relay R3 closes contacts C4, C5 in the supply circuit to the tool PT and closes contacts C3 to provide a holding circuit for itself. A break in either earth circuit causes the relay R1 to open and interrupt the operating circuit for the relay R3. Earth leakage currents flowing from the tool through either or both of the earth circuits cause the energizing of the relay R2 which opens its contacts C2 to interrupt the operating circuit of the relay R3. A resistance M6 is connected in the supply circuit to the tool to increase the impedance of the live side of the supply to prevent a dangerous voltage arising between the tool casing and earth should a short-circuit occur between the live side of the supply and the casing. Specification 892,594 is referred to.
