Title: Process for the texturing of yarns and the like
IPC: D02G1/00
Filed: 1966-06-28
Abstract: 1,154,485. Texturing yarn. ZWIRNEREI UND NAHFADENFABRIK GOGGINGEN WERK DER AACKERMANN GOGGINGEN A.G. 28 June, 1966 [9 July, 1965], No. 29018/66. Heading D1F. A process for producing textured yarn comprises taking an initial yarn having at least two twisted and fixed threads, one of the threads being, an auxiliary disposable thread and destroying the auxiliary thread whilst the threads are in their twisted and fixed condition. The threads in the initial yarn may have the same uniform twist or the non- auxiliary threads or threads may be twisted about the disposable thread; the non-auxiliary yarns may be twisted about the auxiliary yarns in opposed helical windings. The disposable thread may be removed by mechanical means e.g. by passing the thread between a pair of meshing cog wheels (see Fig. 8 not shown) so that the auxiliary thread which in this case is weak and brittle is shredded. Alternatively the auxiliary thread is removed by chemical means, see Figs. 6 and 7 not shown. The non-auxiliary threads may be of natural fibres e.g. cotton fixed by synthetic resin, flax, linen, wool or mineral substances. The auxiliary thread may comprise cellulosic, rayon fibres, alginates, polyvinylalcohols, acetates or other cellulose derivatives or polyamides. The auxiliary thread may not be removed until the initial yarn has been made up into a textile piece. Two examples with numerical data are given illustrating the removal of the auxiliary thread by chemical means.

Title: Magnetic read head positioning system
IPC: H04N5/7826
Filed: 1975-07-11
Abstract: 1518822 Automatic control of magnetic recording PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 11 July 1975 [15 July 1974 14 Jan 1975] 29222/75 Heading G3R A servosystem controls magnetic read head position relative to the centre of a selected track e.g. on magnetic tape for a helical scan or transversal scan video recorder. Each track has data signals and positioning signals of longer wavelength than the data signals. The tracks n-1. n+1, on either side of a selected track n have long wavelength signals which are mutually out of phase (or of different wavelength, Fig. 3, (not shown)) and deviation of the head from a data track causes a servo-control signal to be generated by detecting the positioning signals of adjacent tracks. One method of correcting position of head 1 relative to a track on tape 2 is to control the tape speed using the Fig. lb circuit. Track detector D connected to head 1 generates a servo-control signal which controls reference source B. Switch S is set to read position 1 and source B is compared in circuit V with a velocity signal from tachometer T. Comparator V output feeds a servo-amplifier A which controls the tape motor. During writing, switch S is set to position 2 and tape speed is kept constant by comparing reference source C with tachometer output in phase discriminator E. Alternatively, the head position can be controlled. Circuits for writing the positioning signals, Figs. 4, 6 and 8, (not shown) and circuits for deriving the servo-control signal, Figs. 5, 7 and 9, (not shown) are also described.

Title: Improvements in or relating to hydraulic power control systems
IPC: F15B9/16
Filed: 1953-10-28
Abstract: 740,295. Hydraulic control systems; fluidpressure servomotor-control systems. VICKERS Inc. Oct. 28, 1953 [Nov. 13, 1952], No. 29743/53. Classes 69 (2) and 135. A hydraulic control system comprises a constant displacement pump 158, a motor 172, and a reversing valve 12 controlled by a pilot valve 14 which serves during an initial movement from its neutral position to cause complete shifting of the valve 12, and during further movement to provide variable throttling of the liquid in a pressure passage 80 common to the valves. A regulating valve 18 is subject to the pressure difference across the throttle so that for any particular setting of the pilot valve the flow through passage 80, and hence the flow to the motor, is maintained constant and independent of the load. The parts are shown in neutral position in which the output of the pump is passed through a relief valve 162 to a port 20, and thence past the regulating valve 18 to a tank 154. Under these conditions the pressure in passage 80 is substantially atmospheric, and this pressure, transmitted through a restricted passage 138, allows valve 18 to open as fully as is permitted by a spring 66. The spool 30 of valve 12 is kept in neutral position by springs 32, 34 and the motor 172 is blocked. Manual operation of a handle 178 to move the spool 58 of the pilot valve in a range A produces a minimum rate of movement of the motor. If the spool is moved to the left, passages 52, 54 are connected to the pump and tank respectively. Spool 30 is thus moved to the right, and the liquid flowing into the passage 80 past a land 88 passes through a line 168 to the motor, the exhaust from the motor passing through a line 170 and passages 106, 70, 164 to the tank. The flow is small and is maintained constant and independent of the load resistance by the regulating valve 18. If the spool 58 is moved to the left in range B the circuit is the same as before, but the size of the opening between the bore 56 of the pilot valve and passage 80 is determined by a tapered portion 92 on the spool. Since a constant pressure drop is maintained across this opening by the valve 18, a larger volume of liquid flows to the motor. When the motor has moved to its end position a floating lever 176 restores the pilot valve to its neutral position in which both end chambers of the reversing valve 12 are connected to the tank past lands 122, 124, so that the valve 12 is also restored to its neutral position. Movement of the pilot valve to the right reverses the direction of movement of the motor.

Title: Improvements relating to the manufacture of flat glass in continuous ribbon form
IPC: C03B18/02
Filed: 1955-10-18
Abstract: 797,101. Glass manufacture. PILKINGTON BROS., Ltd., and PILKINGTON, L. A. B. Sept. 4, 1956 [Oct. 18, 1955], No. 29759/55. Class 56. Transparent flat glass is produced as a continuous ribbon and is fire-finished, before entering the annealing lehr, by passing it through a bath of molten metal to cause superficial melting of the glass, the surface being cooled, on emergence from the bath, sufficiently to prevent the conveyer rollers of the lehr from marring the surface. The bath should be at a temperature above 1200‹C. and may be of tin, or predominantly of tin, or if it is required to adjust the specific gravity of the bath to approximate to that of the glass, of 4 parts aluminium to one part tin. The glass ribbon may be formed by vertical drawing from a body of molten glass, but, as shown, is formed by a spout 3 and sizing rollers 7, 10. It is passed between water boxes 11, and is guided into the bath 14 by water-cooled rollers 21. The water box 11 on the underside of the ribbon may be replaced by water-cooled rollers. The bath is heated by heaters 28 and air is prevented from contacting with the bath metal by the admission of a reducing gas, e.g., mains gas to the space beneath the roof 13, by pipes 24, 25. The central parts of the bath are isolated from the atmosphere by seals 23, but, as a further precaution against oxidation, mains gas is admitted and withdrawn through pipes 26, 27. The ribbon, on leaving the bath is cooled by air jets 22 to stiffen the surfaces before meeting the traction roller 19 and the lehr rollers 20. The lehr may be arranged vertically and the ribbon may be formed as described in Specification 722,554. The centre part of the roof may be formed as a depression which dips into the bath, thus obviating the need for a gas supply through pipes 26, 27.
