Title: A speed or ratio measuring and/or controlling device
Inventor: SAVIDGE ALEXANDER BEETHAM
IPC: G01P3/06
Filed: 1971-09-30
Abstract: 1286269 Variable ratio gearing A B SAVIDGE 30 Sept 1971 32559/69 Heading F2D [Also in Division G1] In a speed or ratio measuring and/or controlling device comprising a measuring disc 9, which engages a screw thread on a measuring shaft 10, is in rolling, frictional engagement with a rotatable member 7 and indicates speed or a ratio by its translation along its rotational axis, the pitch angle of the screw thread can be selected to assist transfer of rotational effort from the member 7 to the shaft 10 in a proportion suitable for a particular application of the device by constructing the disc 9, shaft 10 and appended parts in modular form, the interchangeable modules providing different screw thread pitch angles. An indicator provides readings proportional to the movement of the disc 9 from a reference position and may comprise a dial rotatable with respect to a fiduciary mark by a gear train operated by a rack translated by the disc 9 which may be provided with a tyre 12. Limit switches may be provided for remote indication or for retroactive control of the speed or ratio. The speed of any shaft that can frictionally drive a measuring wheel and thence the shaft 10 can be measured if the member 7 is positively driven at a known speed. Applications suggested include miles-pergallon indication when the member 7 may be vehicle driven and the energy transmitted through the disc 9 to the shaft 10 can be made to reinforce the fuel pump drive thereto by using a course pitch thread; yarn-to-machine production rate when the use of a fine pitch thread reduces the risk of breaking the fibre by transmitting too great a tension thereto. The disc 9 may be made of hardened steel. A conical tip 8 of member 7 may be made of urethane and a cone angle of 60 degrees provides a linear relationship of axial translation of disc 9 to diameter of cone section.

Title: Magnetic electron lenses
Inventor: GABOR DENNIS
IPC: H01J29/66
Filed: 1956-10-25
Abstract: 846,897. Electron lenses. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 17, 1957 [Oct. 25, 1956], No. 32584/56. Class 39(1). A magnetic lens for collimating rays emanating from a point O, Fig. 1, consists of a coil 4 wound uniformly on a magnetic member 1 to generate in the space between it and a second magnetic member 2 a leakage field which is zero at the centre and increases linearly, in opposite sign, towards either end of the space. Distortion of the field at the ends of the coil may be connected by additional coils wound around the non-magnetic spacers 3. In Fig. 3 the lens comprises two pairs of tapered pole pieces 6, 6 and 7, 7 energised by coils 9, 9 wound on the yokes 8, 8. The pole pieces may be energised instead by permanent magnets or, preferably, by yokes permanently magnetised to provide half the magnetising field required in combination with coils supplying the other half of the magnetising field. A magnetic screen 10 with a convex front may be provided and to compensate for the presence of the screen, the pole pieces 7 are slightly less tapered than the pole pieces 6 and are also slightly longer. The pole pieces may also be made to bulge in width between the yoke and the tip to avoid cylindrical aberration. The tips of the pole pieces may be bent outwards to secure a better field distribution and the pole pieces may be tapered in the horizontal plane to be convergent in the direction of the lens axis so as to reduce divergent action and to avoid sudden transition into the influence of the lens. The lens axis need not be central. The lenses may be used in the " flat " cathode ray tube of Specifications 739,496 and 794,257. In Fig. 4 the ends of the pole pieces are shown shaped to fit the tube envelope 12 and the yokes 13 and energising coils 9 are outside the envelope.

Filed: 1956-10-26
Abstract: 842,624. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO. Ltd. Sept. 4, 1957 [Oct. 26, 1956], No. 32727/56. Class 38 (3). [Also in Group XXXV] In a control system for an induction motor M, rectifier R 1  converts the rotor current at slip frequency into D.C. which is supplied to an invertor C for conversion into A.C. of the line frequency. During motoring operation, a control circuit GC is adjusted to provide, on the D.C. side of the converter, a voltage which opposes the output voltage of the rectifier but is less than it. In this manner sufficient rotor current is developed for providing a desired motor torque, As the motor accelerates, the driver's lever D is moved to reduce the backvoltage of the invertor until full speed is reached and contactors X are closed to shortcircuit the rotor winding. The motor is braked by applying D.C. to its primary winding, the lever D being again positioned to produce a voltage opposing the rectifier voltage and less than the latter by an amount providing the desired braking torque. In another arrangement, the lever D adjusts a reference voltage which is compared with a speed-responsive voltage for control of the invertor C. Alternatively, the reference voltage may be adjusted by cam-gear in accordance with the position of the conveyance driven by the motor so that a predetermined programme of acceleration, fullspeed operation, and retardation will be automatically afforded. The connections for motoring operation or braking may be established according as the motor speed is below or above a required value. Manual control of the motor speed may be used in conjunction with cam or like gear producing an over-riding control, so that the speed is related to the position of the conveyance at all times, regardless of the position of the driver's lever. The firing of the invertor may be automatically adjusted to prevent excessive acceleration or retardation. Specification 588,209 is referred to.

Abstract: 485,992. Two-way transmission. SIEMENS & HALSKE AKT.-GES. Nov. 29, 1937, No. 32936. Convention date, Nov. 27, 1936. [Class 40 (iv)] [Also in Group XL] A two-way circuit between low and high frequency lines X, Y has a separate modulator M and demodulator M1 feeding a common amplifier V, residual low frequencies in the output of the modulator being suppressed by a filter H. The outgoing and incoming transmissions over line Y may be different side-bands of the same carrier in which case filter H may also be used to suppress the unwanted sideband, the modulator and demodulator being associated with a common oscillator G. Alternatively, different carrier frequencies are used for the two directions and a single oscillator, Fig. 6 (not shown), is used to generate the two frequencies as described in Specification 485,993, [Group XL]. In both cases, the oscillator may operate also as an amplifier for incoming ringing signals as described in the above mentioned Specification. The coupling arrangement between the outputs of filter H and demodulator M1 and the input of the amplifier may comprise a conjugate circuit or, as shown in Fig. 3, it may comprise in series a resistance R1 in the output of H and a constant impedance potential divider R2 in the output of M1, the resistance of the input impedance R3 of the amplifier being large compared with R1, R2. The potential divider provides for manual control of the demodulated signals.
