Title: Improvements in machines for the treatment of textile fabrics with liquids
Inventor: DOWNING SAMUEL
IPC: D06B3/20
Filed: 1963-07-18
Abstract: 1,003,599. Textile treating apparatus. WALKDEN MAKIN & CO., Ltd. July 20, 1964 [July 18, 1963], No. 28391/63. Heading D1L. In a textile treating machine of the type in which fabric passes through a tank in a zig-zag path guided by an upper and a lower series of rollers, the lower rollers being immersed in the treatment liquor, one or more passageways forming jets is/are arranged at or near one or both ends of each roller or on each roller shaft either radial or tangential thereof, and is/are connected to an axial bore in the roller or through the shaft, said bore being in communication with a source of fluid under pressure whereby the fluid issuing from the jet or jets will cause the roller to rotate. In the Figs. A represents a tank through which fabric passes in a zig-zag path guided by an upper series of rollers (not shown) and a lower series of rollers B immersed in the treatment liquid and mounted to rotate in the tank. Each roller B is formed with a central fluid bore b which registers with the bore c in a coupling c bolted to the outside of the tank and connected to a fluid supply pipe D. The bore b is connected by tangential passageways b<SP>1</SP> to the outer periphery such that fluid admitted from pipe D escapes through passageway, b<SP>1</SP> forming jets and causing roller B to rotate. In a second embodiment passageways b<SP>1</SP> are radial and discharge against baffles in a stationary ring in the tank and surrounding the end of the roller. As fluid, steam may be used thus also heating and circulating the liquor in the tank or the treatment liquid itself may be circulated by a pump. Compressed air or other gas may also be used.

In a two-way repeater, attenuators in the " go " and "return" paths under the control of a switching bridge 3 are switched according to the direction of energy flow by signals from a responder 4 connected to the return line and which is controlled by a detector amplifier 5 which blocks the responder when there is energy flowing in the " go " path only but is itself rendered ineffective by inhibitor 6 when energy from B to A produces an equal level in both arms of hybrid H2. The bridge 3 is jointly controlled by responders at A and B, a responder being an arrangement for producing a switching voltage from speech currents. In a modification, Fig. 5 (not shown) the bridge 3 is controlled by a differential bridge connected across the fourwire side of each hybrid. Specifications 701,607 and 703,801 are referred to
Patent GB-1218123-A (GB)
Title: Improvements relating to circuit arrangements for comparing two alternating signals
IPC: G01R23/10
Filed: 1968-06-19
Abstract: 1,218,123. Frequency comparators. SIEMENS A.G. 19 June, 1968 [20 June, 1967], No. 29307/68. Heading H3A. A circuit for comparing the frequencies of two A.C. signals U1, U2 comprises: means, e.g. limiters 1, 2 for providing pulse trains corresponding in frequency to the respective signals; an AND gate 3 receiving the two pulse trains at its input; a circuit 6 for smoothing the AND gate output to provide a triangular signal at the beat frequency; and means 13 for providing an output when the amplitude of the beat frequency exceeds a threshold value. In order to improve the waveform of the triangular signal the limiters 1, 2 also provide antiphase outputs which are fed to a further AND gate 4 and the outputs of both AND gates are fed to the circuit 6 via an OR gate 5. The sense of the error signal is determined by providing a second, similar circuit which is fed with input signals U1 and U2 + #, where U2 + # is a signal at the same frequency as U2 but phase shifted by an angle #. The resulting triangular waveform at D is accordingly phase displaced by # from that at C. The circuits 13, 14 are interconnected so that an output pulse train at the beat frequency is provided on line X or line Y depending on whether U1 or U2 is the higher frequency. Assuming an output on line X, each pulse sets bi-stable 16 and monostable 18 and the bistable is reset by the monostable when it reverts to its stable state. The resulting pulse output signal actuates relay 20 to effect a control e.g. on a motor. Similarly an output on line Y results in relay 19 operating. Unit 13, 14, Fig. 3.-The respective triangular wave signals are applied at C, D and switch on transistors p<SP>1</SP>, p3 whenever their amplitudes exceed the threshold level. These in turn switch on double base diodes p2, p<SP>4</SP> respectively to discharge capacitor K1. If the error is such that p2 switches first, K1 discharges through resistor r4 to provide an output at X, and the subsequent switching of p4 provides no output at Y since K1 is already discharged. Conversely if p4 switches first the output appears at Y and not X.  If it is required that a signal be only generated when the beat frequency exceeds a datum value, a further capacitor (K2), Fig. 5 (not shown), is arranged to be charged to such a value that a double base diode (p5) is fired whenever the frequency is below the required limit. Consequently both capacitors discharge through the double base diode (p5) and not through either r4 or r5, and no output is provided on either X or Y.

[Class 69 (ii)] [See also Group VIII] The upper roller D of a wringer is journalled in a yoke 8 pivoted to a lever 54 which is fulcrummed at 57 and of which the other arm is pivoted to a hollow piston rod 51. The piston 21 works in a cylinder 20 and is raised by fluid pressure derived from a rotary pump 31 whenever a byepass 39 between the upper and lower portions of the cylinder is closed. The valve 44 in the byepass is operable from either side of the wringer. The pump draws from the upper portion of the cylinder through a pipe 26. The hollow piston rod is apertured at 61 and an adjustable spring-pressed ball 62 normally closes an axial passage in the piston but yields at a predetermined pressure, as when articles of undue thickness are passed through the wringer, to relieve the pressure between the rollers. The lower roller E is driven in either direction from a vertical shaft 15 through one of a pair of gears 12 and a clutch 11 operable by an external handle. The shaft 34 driving the rotary pump is constantly driven by the gear wheels 12 through a pinion 38.
