Patent GB-369954-A (GB)
Title: An improved heat energy vehicle with electric power transmission
IPC: H02P9/00
Filed: 1930-09-20
Abstract: 369,954. Controlling motor vehicles. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(Siemens- Schuckertwerke Akt.-Ges. ; Siemensstadt, Berlin.) Sept. 20, 1930, No. 28177. [Class 79 (v).] In a heat-energy vehicle with electrical power transmission and automatic regulation of the generator b to approximately constant torque, and wherein the engine is controlled by adjusting its speed governor d, the excitation of an auxiliary generator c being regulated at the same time, the governor adjusting means e is rigidly coupled with the field controller s during increase of speed but yieldingly coupled thereto during decrease of speed, so that the engine a has time to respond to the adjustment before the excitation of the auxiliary generator changes. The transmission between the drivers controller g and the speed governor d may be such that the engine-speed changes substantially synchronize with the adjustment of the speed regulator during speed increases, but a change of setting to a lower speed may take place without delay or with reduced delay. The speed governor may be controlled in dependence on the speed of the vehicle in combination with or independently of control by the driver. An automatic control of an auxiliary field winding on the auxiliary generator may be included, preventing excessive voltage or current and effective to reduce the charging current to a battery upon a rise in the charging voltage. As shown in Fig. 3, a disc 2, attached to the controller of the field resistance s, is driven positively by a lug 4, engaging a driver 3 on a disc 1 attached to the governor adjusting means, when this is being moved to increase speed, and is driven by a spring 5 in the opposite direction. This movement may be controlled by a pawl and ratchet 6 and a solenoid 9 subject to the current or voltage of the auxiliary generator c. Alternatively an air brake or fan, inoperative when increasing speed, may retard the field controller when increasing speed. A current coil t may prevent movement of the controls upon excessive motor current. Fig. 4 shows an arrangement by which the motor 10 adjusting the speed governor is controlled to maintain a constant speed of the vehicle. A tachometer generator 11 excites a relay 13 to cause the motor 10 to effect an adjustment in one direction or another according to the speed of the vehicle. Adjustment of the field of the generator 11, or of the relay 13, may be used to determine the speed at which the governor shall be operated, and the relay may have damping means preventing its continued oscillation. A resistance 24 may be in circuit with the motor 10 in the position of the relay, so that the governor adjustment to a lower speed setting may be retarded. A brake may be brought into action by the motor current as an alternative. Specification 351,750, [Group XXXV], is referred to.

Title: Method and apparatus for identifying the periodicity of surface defects of strip materials
IPC: G01N21/89
Filed: 1973-06-14
Abstract: 1422880 Photo-electric flaw detectors NIPPON KOKAN KK 14 June 1973 [31 July 1972] 28316/73 Heading G1A The invention relates to detecting the periodicity of surface defects such as scratches or irregular colours in moving strip material such as strip steel. The strip is scanned transversely, e.g. by a mirror drum and light spot in known manner. According to the invention the defect pulse signals 8a above a certain reference level are fed to a shift register 8 comprising a series of flip-flops F1 .... F12. Shift pulses 8b are derived from a strip driven tacho. The outputs from regularly spaced register circuits, (as shown F1, F4, F7 and F10) are connected to an AND-gate G to indicate defects having a spacing of e.g. three times the shift pulse distance on the strip. Additional details:- (i) The number of shift pulses per unit-striplength may be varied by using a frequency divider, or a voltage-pulse converter circuit (13) controlled by a potentiometer energized from the tacno, Fig. 3 (not shown) (ii) Faulty indication due to noise signals operating all registers, may be blocked by connecting all registers to an AND-gate. (iii) Slight "phase shift" (depending on the periodicity of the shift pulses) as the signal passes along the shift register may be compensated by using logical sums of later stages as indicated by dotted lines so that the system responds to F1 + F4 + (F7 or F8) + (F10 or F11 or F12).

Abstract: 489,275. Valve circuits for wireless reception. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Oct. 22, 1936, No. 28729. Convention date, Nov. 2, 1935. [Class 40 (v)] Automatic volume control in a receiver for use with a television system in which the amplitude of the carrier wave is increased by the vision signals from the " black " value and decreased from said value by the synchronizing impulses, is obtained by deriving a potential dependent upon the signal representing minimum picture brightness. As shown the demodulated signals from the diode rectifier 10 are applied to the control grids of valves 13, 15. The synchronizing impulses are separated and phase reversed by valve 13 and applied to an auxiliary grid 3 of the valve 15 to prevent the anode current of the latter from being varied, when the synchronizing impulses are applied to its own control grid. The normal anode current of the valve 15 is thus varied in accordance with the vision signals, the variations in its anode potential being rectified by the diode 19 the output from which is used for A.V.C. after passing a filter 24, 25 the time constant of which is large compared with a line period so that the A.V.C. potential is proportional to the amplitude of the peaks of the vision signals in the " black " direction. Specification 458,585 is referred to.

IPC: H02K3/28
Filed: 1963-07-19
Abstract: 1,098,075. Winding layouts for dynamoelectric machines. MAWDSLEY'S Ltd. Oct. 5, 1964 [July 19, 1963], No. 28788/63. Heading H2A. A machine whose stator windings can be re-connected to simulate machines differing in pole-number, coil-pitch, coil-grouping and coil connection, comprises two double-layer windings wound in the same slots, both ends of every coil of both windings being brought out to external terminals. In the simplest form of the invention, Fig. 1, two identical windings A, B, each of two-thirds pitch with respect to two poles, are used. The upper winding A simulates the M.M.F. produced by the upper layer conductors of a two-layer winding, while the lower winding B which is connected to carry reverse current, simulates the lower layer conductors of a two layer winding. Hence by selective connection of the windings, different coil-pitches of the whole winding can be simulated. By omitting coils, the effect of different, e.g. fractional, numbers of coils per pole per phase may be simulated. By relying on harmonics, higher pole-numbers may be simulated. In the two-thirds pitch winding shown, third harmonics are eliminated, but by suitable connections various higher pole-numbers not a multiple of three may be obtained. Polenumbers which are a multiple of three may be obtained by windings producing odd harmonics, e.g. having half-pitch or full-pitch coils. If desired, the two windings may be of different pitch.

Heading D1E At each side of the loom a selected weft is drawn into measured loop before insertion into a dummy shuttle. A pattern operated selector 46 is lowered, a hook 55 is lowered to bring the selected weft 25 into a guide 10 and a brake 40 and a hook 11 is pivoted slightly anticlockwise deflecting the weft between the selector 46 and guide 10. Measuring hooks 43, 44 are then moved across the loom to draw out a loop of weft and a clamp 82 is lowered to clamp a leg of the loop. The hook 11 is then pivoted slightly clockwise to slacken the weft whilst scissors 22 are pivoted to cut the weft at the selvedge. The hook 11 is then pivoted anticlockwise to draw the cut end out of the brake 40 so that a nozzle 53 may blow it through a dummy shuttle 32, with a gripper 37, into a suction tube 36. As the hooks 43, 43 start to retract a plate 19 is raised to tension the measured loop against bristles &c. 18. As the shuttle is picked the hook 11 pivots anticlockwise and the clamp 82 is opened. To compensate for differing elasticity of yarns they are placed through droppers 15, 16, 17 whose drop may be adjusted. Stop motion. As the loop is drawn blades 31. 35 close upon each other. If, due to lack of weft. the blades penetrate each other the loom is stopped. When the loop has been picked the blades again close and, if they do not penetrate each other, the loom is stopped.
