Title: Clutches
IPC: F16D41/18
Filed: 1965-11-12
Abstract: 1,093,347. Ratchet clutches. EASTMAN KODAK CO. Nov. 12, 1965 [Nov. 25, 1964], No.48053/65. Heading F2C. A one way ratchet clutch comprises an internally-toothed ratchet driven wheel 18 in which a pawl 14 surrounds a driving shaft 10 having a drive key 11 engaged between adjacent tongues 12, 13 of the pawl 14, the pawl 14 being rocked, about its C.G., in one direction of rotational drive of the shaft 10, to engage a tooth 15 on the pawl with one of the internal teeth 17 on the driven wheel 18 for drive thereof (Fig. 2, not shown), whilst drive in the opposite direction causes the key 11 to disengage the pawl tooth 15 and position the pawl completely free of the wheel 18. The correct positioning of the pawl for both engagement and disengagement is controlled by engagement of internal stop faces 24, 27 and 28 of the pawl with the driving shaft 10. To prevent adverse gravity influence on the pawl when operated in certain, e.g. vertical, positions of the clutch, the frictional contact between the pawl 14 and a lower surface (21) of the wheel 18 may be increased by a spring washer (37) held captive together with the pawl by a cap (35) secured to the shaft 10 (Fig. 3, not shown).

Abstract: 1380094 lonization manometers; vacuum switches TOKYO SHIBAURA ELECTRIC CO Ltd 30 Oct 1972 49844/72 Headings H1D and H1N [Also in Division H3] A cold cathode ionization gauge comprises two electrodes 22, 24 in an evacuated envelope, a high voltage pulse generator 32 for applying pulses across the electrodes and means 34 for measuring the discharge current between the electrodes. The pulsed current reduces the exhausting action of the gauge. The gauge comprises a ring anode 22, a spool-like cathode 24 and a permanent magnet 28. The gauge may be an inverted magnetron or Philips type; the magnet may be replaced by a pulsed electromagnet; the electrodes may be those of a vacuum switch. In the latter case the apparatus provides means for ensuring that the vacuum of the switch remains adequate. The high voltage generator comprises a Cockcroft circuit 50 and a condenser 68 connected to a triode 72 which is rendered conductive by square wave pulses applied by generator 84 triggered by similar pulses from another generator 82 controlled by trigger pulses from a monostable multivibrator 80 comprising two transistors. In another generator a full wave rectifier charges a condenser which is discharged through a transformer via a transistor controlled by the pulse generators. The current measuring circuit includes either series resistors and a current maintaining circuit (Fig. 4, not shown) or an integrating circuit. Single or continuous measurements can be made using a driving circuit, including an oscillator, for generating either a single pulse or for periodically generating pulses. When the electrodes are in a vacuum switch the pulse generator (see Division H3) produces pulses having a high initial peak to initiate the discharge.

Title: Improvements in or relating to the detection of peak and/or trough points of a variable electric signal

IPC: G01N30/86
Filed: 1967-11-06
Abstract: 1,208,009. Transistor pulse circuits. GEORGE KENT Ltd. 31 Oct., 1968 [6 Nov., 1967], No. 50420/67. Heading H3T. [Also in Division G1] To detect peak and/or trough points of a variable voltage signal, the signal is applied through a capacitor 12 to an amplifier 14 which is repetitively operated to provide pulses at its output terminal, each pulse being due to a particular amplifier operation and each having a polarity dependant on whether the signal has increased or decreased since the previous amplifier operation. The pulses are applied to an output circuit which provides an output signal having a polarity dependant on the polarity of the last received pulse, whereby the output signal changes in polarity when a peak or trough occurs in the variable signal. The amplifier 14 has an integrating capacitor 20 permanently connected across it and is operated by repetitively applying 100% negative feedback through the resistor 23 by closing the switch 22 in response to signals from a control unit 25. When the switch is opened the amplifier output has a slope proportional to the rate of change of input and an amplitude proportional to the input change since the switch last opened. From the amplifier output pulses, much shorter pulses are obtained by closing the transistor switch 36 in response to the control unit 25 towards the end of the open time of the switch 22. These pulses are passed via the diode impedance network 30 to the bistable trigger 34. So long as the input at 16 is increasing this provides output pulses in one polarity. As soon as the input falls by the amount necessary to overcome hysteresis in the trigger, the trigger switches over to provide output pulses in the other polarity, thus detecting a peak. In alternative arrangements (Figs. 2 and 3) the diode impedance 30 and switch 36 are omitted and an alternative switch equivalent to 36 is included between the trigger circuit output and the final output of the arrangement.
