Title: Improvements in or relating to electro-acoustic translating devices
IPC: H04R9/08
Filed: 1936-06-26
Abstract: 477,408. Sound reproducing and transmitting devices. WILLANS, P. W., and CURRAH,L. E. June 26, 1936, No. 17835. [Class 40 (iv)] In an electro-acoustic translating device in which a strip of conducting material is located in a tube or conduit with its longitudinal axis at right-angles thereto and in which the strip is situated in a magnetic field at right-angles to the longitudinal axis of the strip and to that of the conduit, the area of the strip is substantially less than the normal cross-sectional area of the conduit which is constricted at the strip to approximately the same shape and size as the latter. As shown, cylindrical conduits 1, 2 on both sides of the conducting strip 4 are formed with conical extensions 9 into the walls of which are cut diametrically opposed rectangular slots 7. Tapered polepieces 6 associated with a permanent magnet (not shown) extend into rectangular openings 18 in a brass casing 5 and are formed with bevelled surfaces which produce the constricted cross-section of the conduit at which the conducting strip 4 is located. The outer portions of the polepieces 6 are mainly conical and are positioned in the casing by cylindrical portions 15, 16. The strip 4 is clamped between strips 10, 11 and composite strips 12, 13 formed of upper layers of metal and lower layers of insulating material, and the clamping is effected by grub screws 17 located in milled slots 8 in the casing 5. The dimensions of the slots 7 may be such that the cross-sectional area of each of the conduits increases before it is constricted to an area approximately equal to that of the strip 4. The constriction of the conduit preferably extends over an axial distance less than one quarter of the wave-length of the highest fre.. quency at which the device is intended to operate. Specification 428,144 is referred to.

Title: Improvements in or relating to impulse senders more particularly for use in telephone systems
IPC: H04M1/38
Filed: 1938-06-15
Abstract: 515,952. Impulse transmitters. SIEMENS & HALSKE AKT.-GES. June 15, 1938, No. 17850. Convention date, June 15, 1937. [Class 40 (iv)] An impulse transmitter comprises mechanism similar to a mechanical impulse repeater' controlled by a key-strip. The control mechanism comprises a disc 12 with say 4 x 10 movable pins 11 depressed by the keys through spring-controlled levers 5, 7. The lever 5 carries a member 6 pivoted to move only in one direction as that after tripping the lever 7 during momentary operation of the key, the levers return to normal. Key operation also starts the motor M which is maintained over contacts nk normally engaged by the pin depressed by the preceding key operation. The motor drives shaft 13 which carries the disc 12 and is geared to a hollow shaft 17 carrying a lever 24 adapted to depress one of a series of 4Î 10 pins 26 in a stationary support 18. Rotation of disc 28 under control of a speed regulator 43 is effected by a spring 30 wound up by the hollow shaft, the angular rotation of the disc being determined by the depressed pin 26 and causing by means of gear wheel 44 and cam 45 the transmission of impulses at springs 46. In a modification, Fig. 4 (not shown), the impulse trains transmitted are the complements of those keyed. Circuit arrangement, Fig. 3.-Key operation closes contacts anl whereupon An1 pulls up followed by An2 which releases An1. The operation of An1 energizes magnet 21 which holds and by means of armature 20, Fig. 1, and pin 23 moves lever 24 out of the path of pins 26. The motor M starts up, holds over contacts nk and rotates the pin disc 12 and also the hollow shaft 17 carrying the lever 24 until the depressed pin 11 engages contacts nk which stop the motor and release relay 21 since the operation of AB has left the circuits dependent.on nk. The closure of 3nk operates magnet 34 temporarily in series with H(i) which holds over (ii).and opens the circuit of magnet 34. The magnet 34 restores the pin 26 previously depressed and disc 28 rotates until re-set pin meets the next depressed pin 26 whereupon H (ii) releases.

Title: Data transmission systems
IPC: H04L7/02
Filed: 1964-04-30
Abstract: 996,433. Telegraphy. WESTERN ELECTRIC CO. Inc. April 30, 1964 [May 3, 1963], No. 17915/64. Heading H4P. In a data transmission system which includes self-clocking regenerative repeaters, to ensure the proper operation of the repeaters even if there are gaps between successive characters such gaps are filled with a pattern of signals, e.g. clock pulses, and each character is preceded by a start pulse. At the transmitter, Fig. 1, 7-bit characters read from tape 10 pass to buffer 11. As each character is read out toggle 12 is triggered whereby register 18, under control of clock 19, provides eight sequential markings. The first of these passes via 30, 33 and 36, whereby a space or start bit is transmitted. The remaining markings read out the buffer, the character thus being transmitted. The eighth output resets toggle 12, and the output of gate 29, now zero, enables clock pulses to be transmitted until the next character has been transferred to buffer 11. At the receiver, Fig. 2 (not shown), detection of a start pulse causes the succeeding seven bits to be read in to a register under the control of clock pulses. The seventh clock pulse reads out the register to a tape store.

Title: Improvements in and relating to apparatus for detecting short circuited turns in coils for electrical apparatus
IPC: G01R31/06
Filed: 1944-09-25
Abstract: 615,888. Detecting faults. BRITISH THOMSON-HOUSTON CO., Ltd., DARKE, L., and TITLEY, C. O. Sept. 25, 1944, No. 18271. [Class 37] Short-circuited turns in an electrical coil are detected by arranging the coil in a series resonant circuit fed from a high - frequency source to provide a sensitive state in which the effect of a short-circuit will be great. In Fig. 1, coil L2 forms the grid circuit of a valve T, the anode of which is connected to earth through a coil L1 under test in series with a condenser C. An indicator 1 is connected to a coupling coil L4 which is held near the end of the coil under test L1. Coils L2, L1 have a slight magnetic coupling which is adjusted so that, with a standard coil in position L1, a stable oscillation is obtained as shown by indicator 1. The coil under test is substituted for standard L1 when any short-circuited turns will prevent oscillation. In a modification, Fig. 2, the coil L1 under test is connected in series with a condenser C, across the output of a separate oscillator connected at AA. The oscillator is adjustable as to frequency and amplitude, the output being measured by voltmeter V. Indicator 1 is connected to coupling coil L4. The oscillator is tuned to the resonant frequency of L1, C, with a standard coil in position L1. The reading of indicator 1 is noted with the oscillator voltage V adjusted to some arbitrary level. The coils under test are substituted for the standard coil LI, and any short-circuited turns cause a drop in the reading on indicator 1.

Abstract: 1,068,314. Automatic control. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. May 1, 1964 [May 3, 1963 ], No. 81300/64. Heading G3R. In a system for automatically correcting deviations of a process variable from a preset value by a controller responsive to the error, a manual control potentiometer is maintained in positional correspondence with the voltage applied to the controller in readiness for smooth changeover to manual control and is automatically adjusted so that the error is zero prior to reversion to normal automatic control. As shown, a potentiometer 14 may be manually operated to influence, through a controller 4, a variable of a process 5. The magnitude of the variable is detected at 6 and compared after amplification at 7 with a reference signal selected by a unit 1a or applied at terminal 1b. When it is desired that the variable be automatically maintained equal to the reference signal a switch 10 is closed to cause a supply 9 to energize a unit 11 so that any output from the comparator 2 is effective to operate a motor 12 adjusting potentiometer 14. The closing of switch 10 also renders a unit 8 effective so that when the output of comparator 2 reaches zero, a relay 15 operates to apply the amplified output of unit 2 to controller 4 directly. During such automatic control, a unit 16 comparing the amplified output of comparator 2 with the output of potentiometer 14, controls motor 12 so that potentiometer 14 is maintained in readiness for reversion to manual control without shock to the system. In the event of a fault removing the mains supply, the system changes to manual control with an auxiliary battery supplying potentiometer 14.

Abstract: 984,893. Discharge apparatus. GENERAL ELECTRIC CO. May 14, 1962 [May 15, 1961], No. 18419/62. Heading H1D. Apparatus for removing organic gases from a partially evacuated environment comprises dissociator means for converting the organic gases into their molecular, parti-molecular and atomic constituents and pump for eliminating the constituents. The organic gases may be methane, ethane, flurene or high molecular weight hydrocarbons. They may be decomposed by heat and/or by a chemical catalyst and/or by ionization. Heating is by filaments 27, Fig. 2, of tungsten or rhenium which may be coated with aluminium oxide or by a porous mass of beryllium oxide or aluminium oxide, Fig. 3 (not shown), heated by a heater. The chemical catalyst may be activated alumina, silica, magnesium oxide, carbon, aluminium silicate, platinum or palladium. Ionization is by a directly heated cathode 36 and anode 38. Carbon 40 deposits on the walls of the container and serves as a getter for carbon monoxide and carbon dioxide and for the other organic gas molecule constituents. The chamber has therein or adjacent thereto surfaces of areas of reduced temperature to preferentially receive the carbon deposits and to inhibit desorption. This effect may be produced by artificial cooling or by spacing the surfaces or areas further from the heating elements. Oxygen containing compounds of barium, calcium or strontium are reduced to the metal oxide by the heat and oxidize the constituents of the organic gases, and after reduction to the metal exert a further gettering action on the organic gas constituents. There may be a preliminary molecular filtration means, Fig. 4 (not shown), comprising zeolite, actuated alumina, or charcoal. The preliminary means may be provided with cooling means, e.g. one or more peltier junctions. A vacuum ion pump of the hot or cold cathode variety or a diffusion pump may be used. The pump may contain a heated member of titanium to absorb hydrogen. The premolecular sieve and heating compartment may be an appendage to or integral with the inlet to the vacuum pump.
