Title: Improvements relating to control systems for electrical motors
IPC: G08C19/48
Filed: 1947-04-17
Abstract: 623,239. Rectifying. HIGHAM:, E. H., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 17, 1947, No. 10246. [Class 38 (ii)] [Also in Groups XXXVII and XXXVIII] An electric motor has its rotor or stator winding excited with unidirectional flux and - the alternate winding is polyphase, the coils of each phase being located in series with respective grid-controlled discharge tubes located in a ring-connected circuit and having a common grid coupling-point so arranged that incoming pulses applied to the common grid coupling-point cause the tubes successively to strike and excite the associated phase of the motor so as to effect step-by-step rotation of the motor. The rotor of an electric motor has direct current or permanent magnet excitation, and its stator comprises polyphase windings L1, L2, and L3, which are connected in series with discharge valves V1, V2, and V3, respectively. The valves are connected between bus-bars HT+ and an inner earthed ring, and current-pulses are applied to an outer ring, which is a common coupling-point for the grids, and through condensers C4, C5, and C6, to the grids of the valves. Grid bias is applied from a ring GB through resistors R1-R6. If the valve V1, for example, passes current, the phase winding L1 is energized and the grid potential of the valve V2 becomes such as to prevent that valve from striking, but will enable the next current-impulse to cause it to conduct. The valve V3 is biassed well beyond its critical voltage under these conditions. On receipt of the next current-impulse the valve V2 conducts and the rise of potential at its cathode is transmitted to the cathodes of the valves V1 and V3 through condensers C1, C2, and C3. The valve V1 is cut off, and the valve V3 is prepared for striking at the next impulse. In this way the windings L1, L2, and L3 are energized in sequence by the input signals and the rotor may be advanced thereby in a stepby-step manner.

Title: A fluid-pressure control system
IPC: G05B6/05
Filed: 1960-03-23
Abstract: 942,998. Fluid-pressure servomotor control systems. LEUNA-WERKE WALTER ULBRICHT VEB. March 23,1960 [April 6,1959], No. 10293/60. Heading G3P. A fluid-pressure actuated diaphragm 2, Fig. 1, is coupled to an element, e.g. a valve to be adjusted, by a member 4 provided with a rack portion engageable by a pinion 9 integral with an axially movable clutch-part 10 that co-operates with a fixed clutch part 11 having teeth meshing with a worm 12. Upon failure of the fluid supply a locking diaphragm 6 is moved leftwardly by a spring 7 whereupon the pinion 9 is carried into engagement with the rack and the clutch parts abut so that the member 4 is held in that position but may be operated manually or by some other means from the worm 12. In a modification, fluid is supplied to the control system via a reducing valve 16, Fig. 2, whilst the pressure in the conduit 1, which opens to the diaphragm 2, is controlled by a regulator 14; the pressure in the control system is sensed by a measuring device 15. A bellows 13 supplied with fluid through a restriction 13a has a pair of bleedoff nozzles with which co-operates an obturator 13c carried by the member 4 so that during normal operation the pressures in conduit 1 and bellows 13 are equal, which pressures are conveyed by pipes 13d to a relay 18. The latter is also connected to pipes 14a, transmitting pressures from the regulator 14 and measuring device 15, and a pipe 16a leading from the reducing valve 16. The locking diaphragm is supplied with fluid from any source by a conduit 5 from another reducing valve 19, which conduit 5 is connected to a valve 17 actuate by the relay 18. The pressure in pipe 16a is balanced in the relay by a spring whilst the pressures in pipes 13d and 14a balance each other, any failure or malfunctioning causes operation of the relay 18 and hence the valve 17 whereby fluid is exhausted from the conduit 5 and the locking diaphragm actuates the means to arrest the member 4; the latter may then be manually controlled if desired.

Abstract: 1,096,702. Injection moulding machines. GENERAL ELECTRIC CO. March 11, 1965 [June 10, 1964], No. 10394/65. Heading B5A. Shrinkage of an injection moulded hollow article while cooling is prevented by applying fluid under pressure to the interior of the article. The article can then be more readily removed from a core on which it is moulded, and cooling is facilitated by the improved contact with the external mould walls which are cooled. The air may be forced into the mould cavities shortly before or after or at the same time as the thermoplastic material is injected. The invention is applied to the machine described in Specification 1,096,246 for making insulating sockets for decorative electric lamps. The fluid is introduced through the small space between the two core sections 47, (48) and escapes, until the mould is filled, through a porous metal ring 125 and passage 126. A valve 66 for controlling the supply of fluid is opened at station (C) by mechanism 72 (Fig. 5) and is closed at station (I) by a cam track 70. The valve 66 is opened and closed at station (K) by mechanism (71), Figs. 7, 8 (not shown). Mechanism 72 includes an air cylinder 116<1> for effecting positive movement of the mould locking slides (20, 21) to which it is connected by a yoke 116 and rod 30.

Abstract: 243,666. Sharples Specialty Co., (Assignees of Clark, L. H.). Nov. 29, 1924, [Convention date]. Recovering waste lubricants.- Oils, containing decomposition products, free fatty acids and colloidally suspended substances either naturally or by reason of being used for immersing electric switches, circuit breakers, or transformer coils, or for lubricating internal combustion engines or steam turbines, are treated with an aqueous reagent that has the property of being dispersed more easily than water through the oil and also the property of causing impurities to be removed from the oil. As examples of such a reagent solutions of sodium silicate, particularly a solution in which silica predominates by weight, caustic soda, soda ash, trisodium phosphate, or other alkaline substances are mentioned. The oil to be purified is fed into a tank 1 through a pump 2 and pipe 3 and is then agitated by members 7 with the desired quantity of aqueous reagent supplied through the pipe 5. The mixture may be heated by a steam coil or electric device 6. A pipe 9 leads the heated mixture to a centrifugal separator 10, the aqueous part of the mixture being discharged with the impurities through a spout 11, and the oil passing through a spout 12 into a receiving tank 13. If insufficiently purified the oil is treated by the addition of a small quantity of Fullers earth or similar adsorptive material introduced through a pipe 13', and is then passed into a centrifugal clarifier 15. The oil may be kept in the tank until a desired quantity has accumulated, a ball valve 17 controlling its passage to the clarifier.

Title: Improvements in or relating to arrangements for testing blocks of cigarettes
IPC: B65B19/28
Filed: 1965-03-12
Abstract: 1, 112,687. Inspecting cigarettes. A. SCHMERMUND. March 9, 1966 [March 12, 1965], No. 10480/65. Heading G1A. In an inspecting device for blocks of cigarettes to detect faulty or missing cigarettes the ends of a block, e. g. of 20, cigarettes are illuminated by a source of e.g. infrared or ultraviolet, radiation and the reflected image of the cigarette ends is reflected and focused on a detector,which may be an array of photo-conductive or photomultiplier cells or a vidicon tube, to produce an output in which the absence of a cigarette, or the presence of a faulty cigarette, produces a characteristic output. In the embodiment of Fig. 1 the image of the cigarette ends is focused on an array of photo-conductive cells, an image of one end per cell, and the cells are connected in series in one arm of a bridge circuit. If one cigarette is missing or badly packed, then the light reflected on the corresponding cell will be reduced and the bridge circuit unbalanced to initiate a control or warning effect. The illumination of the cigarette ends may be by a collimated beam of light, Fig. 3 (not shown) or a pair of sources Fig.4 (not shown) and each photo-cell may be replaced by a photomultiplier tube Fig. 7 (not shown). Alternatively the image of the ends may be focused on a vidicon or other camera tube and the cigarette end image scanned by the electron beam so as to produce a discontinuity in the signal output in the absence of a cigarette or the presence of a faulty cigarette. In order to prevent signals arising from the interstices between cigarettes a radiation reflecting mask is arranged over the cigarette ends with only the cigarette ends themselves unmasked so that in the presence of a full block of good cigarettes the output will remain steady as the image is scanned.
