Title: Improvements in or connected with bowden wire and like mechanism
IPC: F16C1/12
Filed: 1920-04-12
Abstract: 166,655. Bowden Wire, Ltd., and Sentinella, A. E. April 12, 1920. Bowden mechanism.-In Bowden and like transmission mechanism for operating two or more control members, such as the fuel and air valves of internal-combustion engines, means are provided for actuating the control members either independently of one another or simultaneously and rapidly by additional Bowden mechanism. In a tube 6, closed at one end by a non-rotatable or integral plug 16 and partially closed at the other end by an integral or attached wall 7, slides a runner-block having a part 9 of complementary section to the wall 7 and an enlargement 13 fitting the tube. The sections 23, 24 of the interrupted sheaths of two or more Bowden mechanisms 25 respectively abut on the parts 16, 9, while the inner wires pass freely therethrough. A master Bowden wire 20 is operatively connected, as by a nipple 21, to the runner-block, and its sheath 22 abuts on the wall 7. In applying the device to the independent and simultaneous actuation of fuel and air valves, the master controlwire is connected to an accelerator-pedal &c. adapted to return to the normal position when released, while the independent actuating-levers &c. may be fitted with friction discs or other means to retain them in adjusted position. The coupling may be made of brass or other metal or material, and is readily turned from stock bar.

Abstract: 842,458. Control of several A.C. motors. BRITISH THOMSON-HOUSTON CO. Ltd. March 28, 1958 [March 29, 1957], No. 10382/57. Class 38 (3). [Also in Group XL (a)] Control rods of a nuclear reactor are operated in sequence by electric motors such as a twophase motor PM which is positioned in correspondence with a transmitter represented by a low-frequency generator T. Phase windings YO, XO of the transmitter are connected through rectifiers MR1, MR2, and reversing switches RS1, RS2 to the phase windings of the motor. Cams COC1, COC2 for operating the reversing switches are driven with the rotor of the transmitter so that phase-displaced voltages are supplied to the respective windings of the motor, the rotor of which is a multipolar permanent magnet. Selector switches are provided to connect successive motors or groups of motors to one low-frequency generator, limit switches operated by movement of the control rods initiating actuation of the selector switches so as to connect the next motor or group in sequence to the generator. The rotor of the transmitter is driven by motor DM through selective gearing controlled by electromagnetic clutch coils FC, SC, or RSC for fast, slow or reverse operation in accordance with the position of a manual switch CSWO. A cam controller CCO, for connecting the motors in succession to the low-frequency generator, is driven by a reversible pilot motor CM, whilst rectifiers MRH1, MRH2, supply directcurrent to hold the rotors of the motors PM in required positions under the control of relays operated by the cam controller. When the first motor operates limit switch LS2, relay RL/SRP prepares for stoppage of rotation, but contact SC is closed only when the voltage derived from rectifier MR2 has positive polarity. For a period, both the cam-controlled relays RL/R1 and RL/H1 are closed so that the rectifiers MR2 and MRH1 share in supplying holding-current to one phase winding of the first motor, the rectifier MRH1 taking the whole of the load when relay RL/R1 is released. When relay RL/SRP is energized, the lowfrequency generator is stopped and the cam controller is started to close relay RL/H1 and release relay RL/R1, and to operate relays for starting the second motor. The cam controller is then stopped and the low-frequency generator is re-started.

Title: Improvements relating to electrical amplifier circuits
Inventor: MATHAMS RONALD FRANK
IPC: G06G7/24
Filed: 1959-03-26
Abstract: 901,467. Electric analogue-calculating systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 15, 1960 [March 26, 1959], No. 10695/59. Class 37. [Also in Group XL (c)] A circuit which provides an output voltage having a value proportional to the logarithm of an input voltage comprises means for chopping the input voltage to produce a square-wave voltage of substantially constant periodicity and amplitude equal to the input voltage, means for differentiating the square-wave voltage so produced to provide an exponentially decaying waveform, means for generating a rectangular waveform of constant amplitude and periodicity equal to that of the square-wave voltage but having a pulse duration equal to the time taken for the differentiated waveform to decay to a predetermined reference voltage and means for smoothing the rectangular waveform to develop the output voltage proportional to the logarithm of the input voltage. The input voltage V 1  is applied to an input terminal of a vibrator D, Fig. 5, so that a square-wave voltage A, Fig. 1, is applied to the input of differentiating circuit CR 1  resulting in a waveform as shown at B being applied to the control grid of valve V 1 . This waveform is amplified in valves V 1 -V 6  and then passed through cathode follower V, to an input electrode of a two-state circuit comprising reciprocally coupled valves V 8 , V 9 . The valve V 8  is normally conducting; however during the intervals t, Fig. 2B, in which the negativegoing portions of the differentiated waveform have a negative voltage in excess of - V 2 , valve V 8  is cut-off and valve V 9  conducts. Thus a square waveform is developed at the anode of valve V 9  with negative-going portions of duration t. It may be shown that the time t is proportional to the logarithm of the input voltage V 1  and hence, by smoothing this waveform, which may be done in a high-gain amplifier provided with negative feed-back, an output proportional to the logarithm of the input is obtained. Valve V 10  acts to limit the negative-going excursions of the anode of V 9  so ensuring that the square-waveform produced thereby is of constant amplitude. The gain of the amplifier stage of the circuit is maintained constant by negative feed-back from the potentiometer network R 2 , R 3  at the output of a cathode follower V 7  to the control grid of valve V 2 .
