Title: Method and apparatus for treating cloth
IPC: D06C21/00
Filed: 1934-05-30
Abstract: 443,556. Shrinking fabrics. WOODHEAD, H. A., Graniteville, South Carolina, U.S.A. May 30, 1934, No. 16129. Convention date, June 6, 1933. [Class 42 (i)] Cloth to be shrunk is subjected to a working action by subjecting the cloth to a thrusting action interiorly of the body of the web. whereby the warp yarns are readjusted and compressed longitudinally and the weft yarns readjusted and brought closer together while surface wrinkling is prevented. The cloth 10 is preferably rendered plastic, e.g. by a sizing operation, and may be tensioned longitudinally to effect an overshrinking of the weft thread, this overshrinking being corrected by curved stretching rolls 21, 22 or other means, and then subjected to the above stated working action between rolls 27, 35. The roll 27 is plain and resilient. The roll 35 consists of a number of plain discs 37 and a number of larger saw-like discs 36 the teeth of which pierce the fabric 10 and effect the longitudinal compression of the warp threads &c. A carrier web 23 consisting of an endless cord as shown in Fig. 5, passes between the rollers 35, 27 and partly encircles the latter. The larger discs 36 of the roller 35 pass through the spaces between adjacent threads of the web 23 to engage the fabric 10. The web 23 and the roll 27 run at the same peripheral speed, but the roller 35 runs faster, its speed depending on the shrinkage required, and being readily adjustable. The shrunk fabric is then calendered, dried, &c. The roller 35 may be replaced by one having card clothing on its circumference, as shown at 69, Fig. 8, and the travelling band 23 by a fixed comb-like structure as shown at 70, Fig. 8. The Specification as open to inspection under Sect. 91 states that the roll 35 may be covered with abrasive material such as carborundum. This subject-matter does not appear in the Specification as accepted.

Patent GB-636409-A (GB)
Title: Improvements in or relating to electric pulse time modulation systems of communication
IPC: H04J3/06
Filed: 1947-06-20
Abstract: 636,409. Multiplex pulse signalling. STANDARD TELEPHONES & CABLES, Ltd. June 20, 1947, No. 16344. Convention date, June 22, 1946. [Class 40 (v)] [Also in Group XL (b)] For demodulating timemodulated pulses, the electron beam of a cathode-ray tube is deflected to a stationary position on a target electrode for a a time which varies with the time modulation of an input pulse. The invention is described with reference to an interlaced pulse multiplex communication system, a multitarget cathode-ray tube being provided having targets corresponding to the individual channels. The incoming interlaced pulse train A, Fig. 2, consisting of double marker pulse 0, and twentyfour channel pulse trains 1 ... 24 is applied from line 11, Fig. 1, to a marker pulse selector, the output of which synchronizes a pulse generator 13. The latter supplies a train B of unmodulated pulses 14 which occur in time substantially mid-way between the signal pulses. The trains A and B are mixed in circuit 15 to produce train C which is fed to an integrating circuit 16 to generate a series of stepped saw-tooth waves D. Alternate risers on this waveform are modulated in time, the remainder being fixed. Thus the riser 32 may be modulated between the limiting positions 32a, 32b. The storage circuit in the integrator 16 is discharged by circuit 38 eight times during the period between two marker pulses as indicated in waveform D and a blanking arrangement (not shown) removes the marker pulse 0 and first fixed pulse 40, curve C, from the pulse train before application to the integrator. The wave D is applied to the vertical deflecting plate 18 of a cathode-ray tube 19. Saw-tooth waves 21 of marker pulse recurrence frequency are generated by circuit 22 and applied to the horizontal deflecting plate 20. In the tube 19 are twenty-four pairs of secondary emitting target electrodes 25, arranged in six rows and eight columns behind corresponding apertures in a collector electrode 24. Each pair of targets such as 35, is controlled by the signals of one channel and is connected to a push-pull amplifier 36. The " treads " of the step waveform represent times during which the beam rests on the appropriate target, and the push-pull output is obtained because the length of time it rests on one element of a pair varies inversely with the length of time it remains on the other element. This is apparent from a consideration for example of the adjacent treads 33, 34, the lengths of which are determined by the position of the riser 32. The target electrodes may be arranged in a single row, the generator 22 being not then required and the integrator circuit 16 being discharged only at the end of each series of channel pulses.
