Abstract: 1,132,067. Liquid level control. KODAK Ltd. Nov.25, 1965 [Nov.27, 1964] No.48441/64. Heading GlH. [Also in Division G2] A flexible container 1 holding photographic processing liquid is connected via tubes 2 and 4 to processing tray 5, and also via a tube 3 to a closed reservoir 6 above tray 5. The reservoir supplies liquid directly to the tray through a tube 7, and an air inlet tube 8 is adjustable in height above the bottom of the tray. Container 1 is compressed by forcing a plate 9 upwards, which squeezes the container against a plate 10. At the, same time, the flexible inlet tube 4 is constricted between projections 12 and 13. Liquid enters both tray 5 and reservoir 6, and the liquid level in the former is then maintained constant by the "chickenfeed" principle. To return liquid to the container 1, the pressure thereon by plate 9 is released. The flexible tube 4 may be replaced by a rigid small-bore tube. The tube 2 may also be made long enough to allow container 1 to be lifted higher than reservoir 6, so that the liquid runs out of it under gravity.

Title: A system for a fishing winch for use more particularly in trawlers
IPC: B66C13/26
Filed: 1963-12-11
Abstract: 988,488. Control of two A.C. motors. J. E. TROTTIER. Dec. 11, 1963 [Dec. 11, 1962], No. 48897/63. Heading H2J. A trawl winch is driven by induction motors M1 M2, with their rotors mechanically coupled, the motor M2 having the lower number of poles and the stator windings of the motors being supplied through induction regulator 1. When a control lever 9 is moved to the left, contactor B4 is closed for forward operation of motor Ml, and, thereafter, contactor M6 is closed for forward operation of motor M2. Movement of the lever 9 to the right closes contactor B5 for reverse operation of the motor Ml. The rotor of the induction regulator 1 is coupled to the lever 9 so that movement of the lever from a central position increases the stator voltage. Initially, contactor B4 is energized through segments 35, 36, for starting the motor M1, the contactor being maintained through centrifugal switch 38. When the rotor reaches a predetermined speed, the centrifugal switch opens but the contactor B4 is still supplied through wattmeter relay 32 until the synchronous speed of motor M1 is reached. The relay 32 then interrupts the circuit for the contactor B4, the contactor B6 being already supplied through contact 22 so that motor M2 drives the trawl at high speed. If the load is then increased to decelerate the motor M2, the centrifugal switch 38 re-connects the motor M1 which adds its torque to the drive. Paying-out of the cable from the winch drive is effected by moving lever 9 to the right, the motor M1 acting as a regenerative brake. At high speeds, the control lever may be moved to the left for reverse-current braking. The induction regulator may be replaced by an alternator having variable excitation. The common rotor 24 is in the form of a tube with water flowing through the tube. In another arrangement, the motors have wound rotors and their speed is controlled by variation of rotor resistance.

Abstract: 1,262,612. Electromechanical delay lines. CHU ASSOCIATES Inc. 21 Oct., 1970 [26 March, 1970], No. 49966/70. Heading H3U. In the frequency-dispersive time delay apparatus disclosed in Specification 1,262,611, the solenoid coil 3 is energized by a circuit 5 so that it produces a non-linear time-varying field. As shown in Fig. 3, the circuit 5 produces from a ramp voltage source V 0  a non-linear output A, B produced by the successive conduction of diodes D 1 , D 2 . This in turn gives rise to a delay versus frequency characteristic having three differently-inclined sections A, B, C. The inclinations of the sections A, B, C may be varied by adjusting the circuit 5; for example, section B may be horizontal or have a negative slope. The non-linear feature gives more flexible control over the time delay characteristic and the bandwidth.

[Also in Division G4]  At the end of a liquid-dispensing operation the value is sensed by a set of pins engaging stepped cams, the pins then halting print wheels in appropriate positions to permit printing the value on a ticket. When the hosecock is lifted from its support pawl 158 is rocked so that the value wheels are zeriosed in known manner by heart cams 37. Simultaneously, bar 69 is pulled to the left to rock stop arms 53 in clockwise direction and withdraw pins 56 from contact with value cams 23. At the beginning of a dispensing operation the lowest value wheel re-engages the zeroising hammers with pawl 158. When the hosecock is returned paper and ribbon are fed and bar 69 returns to the right whereby the pins 56 are moved until they contact steps on the value cams, so positioned stop arms 53. There are two pins 56 and two stop arms 53 to each denomination. One or other of each pair of stop arms 53 engages a stepped abutment 49 or 51 to halt the associated printing wheel 41-45 in its rotation by a motor through a spring coupling (Fig. 13, not shown). The printing hammer 122 and guillotine 123 then operate in known manner. If a value cam 23 stops at transfer point then a abutment 155 prevents movement of arm 154 and operation of the sensing pins 56, so that no printing takes place.
