Title: Improvements in and relating to the control of electric motors
Inventor: JEFFERSON HAROLD FEARNSIDE
IPC: F23H11/00
Filed: 1951-03-06
Abstract: 711,962. Controllers; time switches. BRITISH THOMSON-HOUSTON CO.. Ltd. March 6, 1952 [March 6, 1951], No. 5407/51. Classes 38(3) and 38(5) A device controlling the intermittent energization of a main electric motor comprises a shaft E which carries similar cams J, K, and is driven by a pilot motor through shaft D, chain F, and sprockets G, H. The cam J co-operates with diametrically disposed contact-operating levers (one of which is shown at M) mounted on the casing of the device, whilst the cam K co-operates with another pair of diametrically disposed contactlevers, such as the lever N, mounted with their contacts on a plate P rotatable with spindle R by means of handwheel S. The movable contacts are connected to the motor circuit through slip-rings T and brushes U. When the levers M, N, are aligned their contacts operate in unison so as to close for one half of a revolution of spindle E and open for the other half. The lever N may be moved so that its contact closes in advance of that of the lever M and opens earlier, the period during which both contacts are closed being reduced and the speed of the main motor decreased. The levers diametrically opposed to the levers M, N, are operated half a revolution behind the latter, and their contacts are connected in series with each other and in parallel with the contacts of levers M, N, so that the main motor will be energized twice during a revolution of the spindle E. Thus, adjustment from a condition of continuous energization of the main motor when each pair of contacts are aligned, to a condition of zero entergization when the pair of contacts are 180 degrees apart, is possible. When the controlled motor drives a chain-grate stoker of a boiler, the spindle R may be coupled to a fan speed regulating means, and the levers co-operating with the cam J made manually adjustable, Fig. 6 (not shown). The cams J, K, may be replaced by a drum switch. Specification 683,152 is referred to.

Patent GB-572918-A (GB)
Title: Improvements in multi-channel radio signalling systems
IPC: H04J1/00
Filed: 1942-04-27
Abstract: 572,918. Radio signalling. GENERAL ELECTRIC CO., Ltd., BLIGH, N. R., HELLER, D. M., and STENNING, L. C. April 27, 1942, Nos. 5651 and 9127. [Class 40 (v)] In a radio signalling system, each transmitter and each receiver comprises (a) a standard osoillator having a fundamental frequency fo which is the same for all stations, (b) means for generating a plurality of harmonics of frequency m#0, (c) a variable oscillator whose frequency # covers the whole signalling range, (d) means for establishing a predetermined relationship between frequency f and any selected harmonic mfo, and (e) automatic means for maintaining that relation when established. The Figure shows an embodiment for setting a variable oscillator 9 for transmission or reception over a large number of channels, each related to a selected harmonic of a standard oscillator 1, and in which the selection is assisted by automatic counting means. Oscillator 1, frequency 90 k.c., and oscillator 2, frequency 900 k.c., drive multivibrators 3, 4 which are supplied in known manner with a low-frequenoy A.C. to equalize the amplitude of the various harmonics. The outputs from 3, 4 may be selectively fed by switch 6 through a filter 7 which eliminates harmonics above the useful range, to a mixer 8 where they are combined with oscillations from oscillator 9. After filtering and amplification at 10, they are mixed at 11 with the output from a second standard oscillator 12, the output from which, after filtering, is fed to filters 14, 15 tuned to bands just above and below the frequency at this stage. A.V.C. is applied from this stage to units 10, 11. The outputs from 14, 15 are rectified at 17, 18 and fed through counting relays 19, 20 to a major counter 22 and minor counter 25. This reduces the tedium of finding a high harmonic of oscillator 1. Thus, if the 43rd harmonic is sought, switches 6, 21; 23, 24 are as shown and oscillations from 2 (ten times the frequency of 1) are fed to the apparatus. Oscillator 9 is progressively varied and each time a harmonic of 2 is passed, current passes to relay 19 to operate the major counter 22. After four such occurrences, switches 6, 21 and 24 are thrown and relay 19 operates the minor counter each time a harmonic of 1 is passed through. Thus, after three such occurrences, the oscillator 9 is set for the 43rd harmonic of 1. When this has been done, switches 23, 27 are thrown to connect the outputs of relays 19, 20 to automatic tuning means 26 to maintain the setting. The output from oscillator 9 may be supplied through a doubler 31 to a transmitting amplifier 32, or, a tracking circuit element 33 may be switched in and the output supplied to a receiver mixer 35.

Title: Processes for the catalytic reforming of light gasoline fractions
IPC: C10G35/085
Filed: 1955-02-28
Abstract: A light paraffinic gasoline fraction which boils at temperatures up to 95 DEG C. to 110 DEG C. is fractionally distilled to separate it at a temperature between 55 DEG C. and 75 DEG C. into a lower boiling fraction and a higher boiling fraction and the higher boiling fraction is catalytically reformed and the resulting reformed product blended with the lower boiling fraction.  The separation preferably is effected at 65 DEG C.  The higher boiling fraction preferably is reformed using platinum as catalyst on a carrier such as alumina, silica-alumina or silica-magnesia, but the catalyst may be molybdenum oxide or chromium oxide on alumina.  The catalytic reforming is effected in the presence of hydrogen at a temperature between 450 DEG C. and 550 DEG C. and a pressure between 2 and 100 atmospheres. Tetra-ethyl lead may be added to the blend.  In an example a gasoline boiling between 30 DEG C. and 93 DEG C. is separated by distillation and the fraction boiling between 65 DEG C. and 93 DEG C. is reformed using a platinum catalyst, and then blended with the unreformed fraction.

Title: Improvements relating to the driving of blowers, fans, or the like by internal-combustion engines
IPC: F02B33/00
Filed: 1942-05-02
Abstract: 558,149. Scavenging and supercharging blowers. HARPER, W. A., and REBBECK, Sir F. E. May 2, 1942, No. 5943. [Class 7 (ii)] [Also in Groups XXIV and XXVI] Relates to the driving by internalcombustion engines of scavenging and supercharging blowers and has for object the prevention of excessive strains in the transmission mechanism during starting and stopping of the drive. According to the invention, the drive consists of epicyclic gearing the planet carrier of which is automatically brake-controlled in such a manner that it has restrained rotation during starting and stopping, but is held during normal running. The engine drives, through a chain, a wheel a keyed to a casing b having internal teeth engaged by planets c which drive a sun wheel d keyed to the shaft e of the blower &c. The planets are mounted in a carrier g, h to the sleeve of which is keyed a cam or eccentric l adapted to be loaded by a roller m mounted on a piston n and subjected to the pressure of a spring o and of air trapped within the piston n and between the walls p, p' of the cylinder and its jacket. The cam or eccentric is symmetrical and, to prevent it from moving beyond an angle of 180 degrees and changing the direction of its torque, an abutment v is provided to limit the travel of the piston n. In a modification, the brake takes the form of interleaved friction plates adjustably loaded by springs. Alternatively, the brake may be a friction band engaging a pulley on the planet carrier.

IPC: B23K9/12
Filed: 1960-02-19
Abstract: 971,695. Control of A.C. motors. BRITISH OXYGEN CO. Ltd. Feb. 16, 1961 [Feb. 19, 1960], No. 6043/60. Heading H2J. [Also in Divisions B3 and G3] In a welding system, an electrode-feed motor having armature 40 and field winding 41 is inched in either direction by actuating switch F or G, the armature and field winding being connected in series across the auxiliary winding 24 of transformer 19. To prepare for welding contacts E1-E3 are closed, and a contactor having contacts D1-D3 is energized. A field winding 15 of generator 13 is excited, the generator being driven by motor 10 to apply voltage between electrode 16 and work 18. The electrode-feed motor is still connected as a series motor across the winding 24, the electrode being moved towards the work until relay C is energized by the welding-current. The armature 40 and field winding 41 are then connected in parallel across the welding-arc. During the welding operation, a dynamic braking resistor 46 is connected across the armature 40. A variation in arc-length during welding alters the voltage applied to the feed-motor, so that if the length of the arc increases or decreases, the speed of the motor increases or decreases. In another arrangement, the welding current is obtained from a transformer, Fig. 2 (not shown). In a further embodiment, the field winding 41 is supplied from the winding 24 during the welding operation, Fig. 3 (not shown).

Title: Improvements in or relating to Slack Adjusters for Disc Brakes
IPC: F16D65/14
Filed: 1968-02-07
Abstract: 1,154,449. Automatic slack adjustment of disc brakes. ALFRED TEVES G.m.b.H. 7 Feb., 1968 [20 May, 1967], No. 6056/68. Heading F2E. A sleeve threaded on an axial rod in a brake cylinder for a spot type disc brake has inclined surfaces which engage corresponding slant surfaces on a collar whereby excess movement of the piston during hydraulic operation causes the slant surfaces on the collar to rotate the sleeve on the threaded rod and so take up the slack. Piston 2 in cylinder 1 is actuated either by fluid pressure or by means of a hand brake lever (not shown) which moves a threaded rod 3 to the left, carrying with it a threaded sleeve 4 and the piston. Initial movement of the piston under fluid pressure takes up the clearance between a cage 6 and a member 9 secured to the piston. Further movement moves the cage and a collar 5, the latter having inner slant-wise teeth 8 (Fig. 3) urged by springs 12 into engagement with corresponding teeth 7 on the sleeve 4 so that the sleeve is rotated on the threaded rod to take up slack. Upon release of the pressure the piston returns by the amount of the clearance between 6 and 9 and the sleeve is not screwed back, due to the release of a one way rotary coupling provided by rollers 13 (Fig. 2) in ramps 15. When the pads are to be replaced the slack adjuster may be returned by rotating the piston or the screw.

Abstract: <PICT:1017871/C4-C5/1> A combustible gas is made by a cyclic process which includes a plant-heating and gas-making periods, the process comprising gasifying a hydrocarbon oil with a hydrogen-containing gas (steam) in a zone 27, gasifying solid fuel (coke) with steam in a second zone 1, washing the oil gas and the water gas separately at 88, 65 respectively, passing the washed water gas through a heated, catalytic co-conversion apparatus 78, mixing the washed oil gas and the converted water gas, e.g. at 100, and generating blow gases from the coke in the zone 1 to heat that zone, and combusting the blow gases, e.g. at 16, to heat the zone 27. The apparatus operates as follows:-(a) During plant-heating, valves 9, 15, 60 are open and the rest shut, air being supplied through a pipe 8 to the coke 6 to form blow gases which are combusted at 16 by admitting secondary air through a pipe 17.  Fuel oil may be burnt at 31, and hot gases pass via fixing chamber 41 and riser conduit 44 to a waste heat boiler 57 and atmosphere at 60.  Free CO may be combusted in 44 by admitting tertiary air at 49, (b) steam purging of zones 1, 27 and 42, 44 from pipes 11, 28 follows, (c) up-run gas-making is started by opening valves 21, 104, and closing 15, 60.  Steam is admitted by pipe 11 to the zone 1, water gas passing to the wash box 65, scrubber 68, and a holder 73. Simultaneously, oil gas is made at 27, by steam entering at 28 and oil at 39, the gas being "fixed" at 42, washed at 88 and cooled and scrubbed at 93, (d) water gas is made during a back-run, where steam is passed from 54 through the chamber 42 and zones 27, 1, water gas passing via pipe 25 or (e) during a down-run, where steam is admitted to the zone 1 at 62, valve 15 being closed.  Oil gas may be made during the down-run, (f) steam purging from 11 via zone 1 to the wash box 65 completes the cycle. The water gas is boosted at 76 and after CO-conversion at 78, passes via a cooler 82 to join the oil gas in holder 100.  Two specific examples are described.

Abstract: 1536961 Stereophonic receivers SIEMENS AG 18 Feb 1976 [13 March 1975] 06290/76 Heading H4R In a frequency modulated stereophonic signal receiver the multiplex signal is fed to the decoder circuit via a differential amplifier 5 having a feedback circuit including an RC circuit R K , C K  which provides compensation for the frequency and phase response of the connection line between the demodulator and decoder, which forms effectively a low pass filter R A C A . The arrangement reduces cross-talk which can be produced if the amplitude and phase of the L+R and L-R signals are not correct. As described, the multiplex input signal MPX is applied to a differential amplifier 18, 19, having a current mirror circuit in its collector circuits. The output from transistor 18 is fed via amplifier transistor 25 to the output terminal 8 and also via RC circuit 9, 10, as negative feedback to the base of transistor 19 of the differential amplifier. The RC circuit 9, 10, provides the frequency characteristic compensation while the resistor 11 prevents the gain of the circuit becoming too high at high frequencies, i.e. above the stereo signal band. The circuit can be produced in integrated form.
