Title: Improvements in or relating to hydraulic valves and hydraulic servo-systems
IPC: F15B9/10
Filed: 1958-11-05
Abstract: 860,933. Fluid-pressure servomotor-control systems. LEDUC, R. Nov. 5, 1958 [Nov. 5, 1957], No. 35517/58. Class 135. An hydraulic servo-control valve comprises a main valve 1 spring-urged to close, a doubleacting hydraulic valve actuator, e.g. piston 5, having damping means formed by a calibrated leak-path from inlet I between the piston, and its cylinder to chamber 12 and on unsprung pilot ball valve 10 push-operated at 3 for controlling a piston passage 8 leading to the valve outlet displacement of valve 1, as a result of unseating ball 10, tending to reseat the ball. Movement of rod 17 and cam 4 to the right opens ball 10 of valve 20 and allows inlet pressure at I to open valve 20 and follow up the movement of the ball so that inlet pressure acts at 18 on the large area of the differential piston 7 and moves it to the right. Cam 4a on rod 17 moves away from the push rod of valve 20a to keep it closed. According to Specification 654,415 referred to, rod 17 is moved manually and piston 7 operates aircraft surfaces. Movement of rod 17 to the left enables cam 4a to open valve 20a via its ball 10 and keep valve 20 closed so that inlet pressure acts at 19 on the small area of the piston and the large area is open to exhaust at E via a passage around the cams and between the valves 20, 20a, through open valve 20a and around the righthand end of the piston. Movement of the piston with respect to rod 17 recloses either of valves 20, 20a so that the piston occupies a distinct position for every position of rod 17. The cams on rod 17 may be linear or curved.

Title: Improved method and apparatus for treating textile yarns
IPC: D02G1/16
Filed: 1962-09-18
Abstract: 1,023,944. Separating liquid particles from gases. EASTMAN KODAK CO. Sept.18, 1962 [Sept. 18, 1961], No. 35570/62. Heading BIT. [Also in Divisions B5, Dl and F4] A method of treating textile yarn previously treated with lubricant or other liquid comprises feeding the yarn through a jet under the influence of high velocity air or other gas which tends to strip the liquid from the yarn to form a fine mist, confining the mist-laden atmosphere in the vicinity of the jet and causing it to impinge on a direction-changing and condensing surface. The gas jet can entangle the filaments of the yarn and/or bulk the yarn, or alternatively be used to remove excess liquid from a yarn emerging from a coagulating bath -such as used in wet spinning-or from a washing, hotwater drafting, dyeing, or sizing step. As shown, the condensing surface 23 comprises the removable top of a housing 10. The yarn, possibly direct from dry or wet spinning, or from a lubricating step, Fig. 1 (not shown), is first threaded through the ceramic eyelets 17, 18 of a jet 9 and over ceramic guides 11, 12 on the housing 10, and then the top 23 weighed at 24 is placed on the jet with the yarn passing through slitted ceramic eyelets 25. The liquid which condenses on the surface 23 drains away through a pipe 22, while gas from the jet 9 and air drawn in through gaps 32 in the housing are removed through a conduit 20 to a low section exhaust system, or into the room environment via possibly air filters. Alternatively the side walls, which are either curved or comprise a series of plane segments, of the housing 10 may act as the condensing surface, with the gas jet removable upwards into a threading position.

IPC: G11B15/28
Filed: 1959-10-28
Abstract: 896,088. Driving magnetic tapes. EPSYLON RESEARCH & DEVELOPMENT CO. Ltd. Aug. 3, 1960 [Oct. 28, 1959], No. 36528/59. Class 40 (2). The tape spool carriers 17, 19, Fig. 1, of a tape recorder are mounted at 16, 18, Fig. 2, on respective levers 12, 13 pivoted at 14, 15 to the deck plate 11, the levers being rocked through a cam 37 or by solenoids, Fig. 11 (not shown), to move the spool carriers laterally to effect the appropriate controls. In the " record " and " replay " positions of the cam control knob 39, the tape is traversed past the erase and record/ replay heads 60, 61 by the usual capstan 47 and pinch roller 52, belt driven from the spindle of the motor-driven friction wheel 28, and wound on to a spool on the spool carrier 17 belt-driven from the capstan. In the " spool left " control positions of knob 39 the spool carrier 19 is rocked into engagement with the driving-wheel 28 to effect fast rewind. In the " spool right " position the spool carrier 17 is rocked to force a jockey pulley 29 into engagement with the drive wheel 28 to effect fast rotation of carrier 17 in the opposition direction. In the " stop " positions both spool carriers are or tend to be driven in opposite directions-but are braked to rest by the tape, The pinch roller is moved out of engagement with the capstan by a further cam in all positions of the control knob 39, except record and replay, and the motor circuit and the circuitry of the record/playback amplifier are controlled by wafer switches also actuated by the cam-shaft. During transducing the take-up spool carrier 17 is lightly driven by a friction disc 64 lying on the upper face of a pulley 63 driven by the motor to provide a friction drive, Fig. 3. Accidental erasure is prevented by a step formed on the bottom of knob 39, engaged by a pin which prevents the knob from being moved unless it is simultaneously lifted against the pull of a spring (not shown). The electronic circuiting of the associated record/playback amplifier is mounted on two wafer plates 74, 75 of the switch 70, Fig. 3.

Title: Improvements relating to displacement measuring and position control devices
Inventor: LOGAN ALLAN BEATTIE
IPC: G01D5/38
Filed: 1954-12-18
Abstract: 821,224. Programming for machine-tools. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 7, 1955 [Dec. 18, 1954], No. 36665/54. Class 83 (3) [Also in Groups XXXVIII and XL (b)] A displacement-measuring device, with which may be associated position-control means, consists of two co-operating optical gratings producing a specific light pattern which, on relative movement of the gratings, undergoes a corresponding and magnified movement, and means for repetitively scanning the light pattern to produce an electric signal phase modulated in dependence on the movement. As shown, one of the gratings 8 is attached to a nut 11 which may be secured, e.g., to a machine-tool worktable. The nut works along a lead-screw 12 driven by servomotor 13. Collimated-light is directed through grating 8 and through a second grating 9 having rulings of the same spacing as those of grating 8, but inclined to the latter at a slight angle. A lens-system is used if necessary to focus the light output in the plane of a rotating shutter 6 having slots 7, and light passing through a slot reaches photo-cell 10. In position-control operation, movement may be controlled by a magnetic tape record 1 having a reference oscillation recorded on one track (2), and a control signal recorded on a second track. The reference signal is derived by head 3 and used to synchronize motor 5, which drives shutter disc 6. The control signal is derived by head 15 and fed to one input of phase-discriminator 14. The output of the photo-cell, which effectively views a vertically-moving horizontal line across the two gratings, is fed to pulseshaper 17 to give a large amplitude-output at the time of maximum light intensity, which output forms the other input of discriminator 14. The output of the discriminator is applied as an error-signal to servo-motor 13, which operates to cause the work-table unit to move in accordance with the recorded control signals. In a modification (Fig. 2), scanning is effected by a cathode-ray tube 20 having a horizontal fanbeam, or a rapid horizontal scan, the vertical scanning waveform being generated at 22 and synchronized with the reference-signals from the tape. The rest of the system functions as in the previous embodiment. The apparatus may be re-arranged to cause one member to follow the movement of another member (Fig. 3, not shown). In this embodiment the generator 22 is not synchronized, and a portion of its output is compared with the shaped photo-cell signals in the discriminator. One grating is attached to the primary member and the other to the following member, which is driven by the servomotor in accordance with the discriminator error signal output. Specifications 669,849, [Group XXXII], and 797, 503 are referred to.
