Title: Device for the protection of enclosed premises
IPC: G08B13/24
Filed: 1947-06-26
Abstract: 640,929. Burglar and like alarms. GRIESSER, W. June 26, 1947, No. 16864. Drawings to Specification. [Class 118 (i)] A device for the protection of enclosed premises comprises an ultra-short wave radio transmitter radiating an audio-frequency modulated directional beam which is received by a directional receiver and causes a relay under control of the receiver to be held in its non- alarm position. Transmitter and receiver circuits are described and illustrated in Figs. 1 and 2 respectively (not shown). The transmitter consists of a triode A.F. oscillator modulating a triode R.F. oscillator directly coupled to an aerial. The receiver consists of a diode detector stage, a triode-pentode twostage amplifier and a further diode arranged to rectify the A.F. to give a positive control voltage on the grid of a final pentode (biassed to class C operation) causing it to pass current through a relay in its anode circuit and thereby hold alarm contacts open. If the radio beam is interrupted, by a burglar for example, the receiver detects no A.F., the positive control voltage ceases and the final pentode cuts off, thereby releasing the relay which closes the alarm contacts. On restoration of the signal the alarm relay is not automatically reenergized since on release it breaks its own circuit and the alarm will continue until the device is reset by depressing a push-button which bridges the relay " hold " contacts. A separate source of power, e.g. an accumulator battery, is provided for the alarm which will then also operate if the mains supply fails or the transmitter or receiver are damaged. The aerials of both transmitter and receiver comprise tuned coils arranged in front of reflectors enabling the apparatus to be made in totally enclosed units, the emitting and receiving sides being closed by highly insulating material. The tuning may be achieved by wing members pivotally mounted on the reflectors. The transmitter and receiver each contain their' own power packs but the transmitter may have its rectifier and modulator omitted and be fed by raw A.C.

Title: Improvements in means for and methods of automatically controlling the melting of coating on continuous metallic strips
IPC: C25D5/50
Filed: 1944-09-07
Abstract: 596,854. Electric control systems. TRIGGS, W. W. (Carnegkie-Illinois Steel Corporation). Sept. 7, 1944, No. 17118. [Class 40 (i)] [Also in Group XXXVI] A means for automatically controlling the heating of a continuous metal strip and bright melting an electrolytically deposited coating of tin thereon in which an electric current is passed through the strip, comprises a conductor roll, means for supplying a heating current to the roll and the strip, means controlled by the speed of the strip for establishing a reference voltage, the voltage output of which varies as the speed of the strip varies, means for balancing the heating voltage against the reference voltage and means responsive to the difference between heating voltage and reference voltage for varying the heating voltage supplied to the strip as its speed varies. As shown, the strip S is passed through a resistance heating unit comprising conducting rolls 2 and 3, the source of heating power for the unit being a pair of transformers 9 and 10, the secondaries of which are in parallel with each other and the conducting rolls 2 and 3. The output of the transformers is controlled by a pair of reactor transformers 18 and 19, the transformers 9, 10 and 18 and 19 being arranged as described in Specification 596,857, [Group XXXV]. A rectifier 29 connected to a tachometer generator 30, of the type described in Specification 596,856, [Group XXXV], driven by the driving means for the strip S is connected to the lines 14 or 15 supplying heating current to the strip. An electronic control of the type described in Specification 596,855, [Group XXXV], is used to match the output from the transformers 9 and 10 and any deviation or unbalance between these voltages will cause a motor operated rheostat 25 to be moved in the direction to restore balance. The voltage applied to the strip is sufficient, for the selected speed of the strip, to cause the coating just to'be melted before it is quenched; Specification 557,029, [Group XXXVI], also is referred to.

Title: Improvements in or relating to methods of, and arrangements for, operating a d.c. electrical motor
IPC: B60L7/12
Filed: 1970-04-10
Abstract: 1301119 Control of DC motors SOC GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM) 10 April 1970 [14 April 1969] 17267/70 Heading H2J A separately excited D.C. motor having a chopper 5 comprising thyristors 10, 13, 14, capacitor 12 and coil 11 in its armature circuit, and a similar chopper circuit 7 in its field circuit is operated in a braking mode by rendering circuit 5 inactive, and passing armature current to a resistor 20 in series with a thyristor 21. At the end of braking, during which circuit 7 has operated normally, with thyristor 28 fired whenever 15 is extinguished, so that 28 has acted as a freewheel diode, thyristor 21 is extinguished by transiently passing a reverse current through the winding 6, thus reversing the current in the armature. The reverse current is produced by not igniting thyristor 28, so that the capacitor 29 is charged via diode 33, and subsequently discharged through winding 6, by firing thyristor 31, whence reverse current flows in winding 6. Coupling between coils 16 and 32 extinguishes thyristor 31 and ensures cancellation of the reverse current as soon as thyristor 15 is fired again to resume motoring operation. A voltage limiter 30, which may be a Zener diode, is connected in parallel with capacitor 29. The current reversal may alternatively be obtained by feeding the field via a thyristor bridge. The system is applicable to fuel cell or battery driven vehicles.

Abstract: 1,083,223. Orientating disc-like partitions. H. GIEHLER. April 26, 1965 [June 16, 1964; Oct. 14, 1964], No. 17459/65. Heading B8S. [Also in Division B5] An extruded synthetic plastic tube or extended profile 4, e.g. a channel of U-cross section, is provided with partitions 7 also of synthetic plastic material, which are inserted into the tube from a magazine 14 by a fluid-pressure operated plunger 8. In the embodiment shown, particularly intended for partitioning tubes of circular cross-section, each partition 7 is provided with a helical resistance wire 7a and diametrically opposed contacts 7b, and the head 9 of plunger 8 has contacts 12a attached to supply leads 12. In operation, a partition 7 is removed from the magazine and at the appropriate position is held against a suction head 10 by retraction of a conical valve 11a to provide a partial vacuum derived from a conduit 11. The partition is fused in position by passage of an electric current through wire 7a. To ensure that connection is made between contacts 7b and 12a and hence supply leads 12, channel 3 of die head 2 is internally grooved and each partition is rotated by co-operation of a nose 7c with the grooving until the contacts abut, the resistance to rotation then being considerably greater than the force of rotation. Modifications include mechanical or magnetic holding means instead of suction cup 10, particularly when apertured partitions are used, creation of a partial vacuum within plunger 8 instead of by external means and dispensing with the need to rotate the partitions by providing them with semi-circular contacts. In a second embodiment, Fig. 3 (not shown), more particularly for partitioning extended profiles, e.g. for use as cover troughs for long field lights, a reciprocable plunger (8a) has an axially reciprocable screw impeller (16) and the partitions (7) each have a peripheral groove (7<SP>1</SP>) communicating with the inner surface of the partition by means of ducts (20). In operation, plunger (8a) positions a partition appropriately within profile (4) and the partition is secured in position by material injected via outlets (21) and ducts (20) to groove (7<SP>1</SP>) by axial movement of screw (16).
