Title: Improvements in or relating to remote indication systems
IPC: G08C19/12
Filed: 1942-03-13
Abstract: 553,286. Position-indicating systems. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). March 13, 1942, No. 3376. [Class 40 (i)] [Also in Group XL] The angular position of a shaft, such as a switch shaft, is remotely indicated by shifting the phase of a reference A.C. and producing therefrom a train of pulses, one per cycle, which are used in conjunction with the reference wave to give an indication on a cathode ray tube or other low inertia device. Indications in respect of a number of shafts may be transmitted with the help of distributers ; summation may be effected by subjecting the reference A.C. to successive phase shifts corresponding to the positions of several shafts. The conversion of the phase-shifted A.C. into impulses may be performed at the transmitter or receiver. Phase shift is effected by supplying the reference A.C. in quadrature to a pair of fixed coils intersecting at right angles, output being taken from a coil rotatable about the axis of intersection and positioned by the shaft. The frequency should be high enough to permit the use of air-cored coils but a low reference and pulse frequency may be used by modulating a higher frequency for phase shifting, followed immediately by rectification. Such an arrangement is shown in Fig. 6 in which low reference frequency in quadrature from 14 and high frequency in quadrature from 15 are supplied to a, twin modulator 16 which feeds the phaseshifter 13 controlled by shaft 12. The phaseshifter output is rectified at 17 and supplied to a pulse generator 8 producing one pulse per cycle, the pulses and the reference wave from 14 being used to modulate a wireless transmitter 19. A monitoring cathode ray oscillograph may be connected to leads 21-23. At the receiver, Fig. 7, the detector 25 is followed by high and low pass filters 26, 27 which separate the pulses from the reference wave and apply both to the control circuit 9 of a cathode ray tube 10. In a multiplex system, Figs. 8 and 9 (not shown),the phase-shifters for several shafts are supplied by common devices corresponding to 14-16, Fig. 6 and their outputs are fed over a rotary distributor to common devices corresponding to 17, 8 and 19. The distributer is driven by a motor supplied with the reference wave and also controls a square pulse generator which interrupts the radiated wave once per revolution for giving synchronizing indications at the receiving distributer the motor of which is also supplied with the reference wave. A number of shaft position indications could be given on a single cathode ray tube.

Title: Improvements in or relating to circuit arrangements for setting electric alternatorsinto operation and switching arrangements in x-ray installations
IPC: H05G1/48
Filed: 1931-02-03
Abstract: 372,747. Rontgen - ray apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel. Eindhoven, Holland. Feb. 3, 1931, No. 3483. Convention date, Feb. 22, 1930. [Class 98 (i).] An X-ray installation, operated from an internal combustion engine is shown diagrammatically in Fig. 2. The engine drives a generator wound with direct and alternating current windings, the former exciting the field winding 6. The X-ray apparatus is excited from a transformer 14, and the circuits are controlled by a swit h 17 enabling the time of exposure to be pre-set. In the idle condition shown, the A.C. winding of the generator is short-circuited through a contact on a lever 33 controlled by a pushbutton 29 which is pressed to make the exposure, and a contact on a lever 31, the load circuit, i.e. the primary winding of the transformer 14, and the resistance 9 are each short-circuited through a fixed contact member 32 engaged by the aforesaid contact levers. In setting the dial of the switch to determine the exposure time, a cam disc 36 closes the field circuit by operating a contact lever 30, and opens the short-circuit on the armature winding and resistance 9 by moving the cam disc 37 through an angle 34 and operating the contact lever 31. The resistance 9 is lower than the load resistance, and is included in the field circuit at this stage. When the button 29 is pressed to start the exposure, the transformer 14 is thrown into circuit with the resistance 9 and generator armature by the operation of contact lever 33, and the disc 36 is released. After moving backward and carrying the disc 37 through the angle 34, the contact lever 31 short-circuits the resistance 9, the transformer becomes fully excited and the exposure commences. When the disc 36 has returned to its initial position, the field circuit is interrupted by the contact lever 30, the pushbutton 29 being released to short-circuit the generator and load as before. The timing switch is shown in Fig. 3, the dial readings being displaced from zero by the angle 34 to allow for the preliminary switching-on condition in which the resistance 9 is in series with the transformer.

Abstract: 694,553. Heat-storing apparatus. TELKES, M. Feb. 12, 1952 [Feb. 19, 1951], No. 3673/52. Class 64 (ii) A material for the storage of heat, e.g. solar heat or waste heat extracted during refrigeration, consists by weight of 1-5 per cent borax, the balance being sodium sulphate and water of which the sodium sulphate is 34-44 per cent on an anhydrous basis by weight. The balance may be Glauber's salt. The borax prevents its supercooling and the formation of heptahydrate of sodium sulphate during crystallization and inhibits corrosion of the container, although sodium chromate or dichromate (0.5 per cent) also may be added for this last purpose. The material is used in sealed, steel containers 11 stacked in tiers in a bin B, the tops 11 a of the containers in a tier being in heat transfer contact with the bottoms 11b of the containers in the tier above. Small spaces 13 are provided for the circulation of air or other heattransfer fluid between the containers in each tier.
