Title: Improvements in and relating to the treatment of synthetic yarns and threads
Inventor: SCRAGG ERNEST PHILLIP RUSHTON
IPC: D02G1/02
Filed: 1957-07-11
Abstract: 850,693. Crimping yarns; textile machines, heating arrangements. SCRAGG & SONS Ltd., E. July 7, 1958 [July 11, 1957], No. 21962/57. Classes 120(2) and 120(3). [Also in Group XI] Crimped, bulky yarn is produced by subjecting a thermoplastic synthetic yarn to successive treatments of (a) crimping by heating (as it is withdrawn from a package) so as to soften it, imparting a high degree of twist whilst hot, setting the twist by cooling and untwisting and (b) stabilising the reheating whilst rumning and allowing it to contract or relax by a pre-determined amount, cooling and winding. In the operation at one station of a modified uptwister, Fig. 1, yarn balloons off a package 11 to pass through a guide 12 over a driven nip roller 13 on to which yarn is pressed by a free roller 14, thence over the convex surface of an electrically heated plate 15 via a channel or groove therein, through a false-twist spindle 17, and air space 19 (wherein the yarn is cooled to set the twist). The yarn is withdrawn through nip rollers 20, 21, the former being driven at a feed speed 2% less than that of roller 13 so that the yarn is tensioned to limit contraction and resultant bulking of the yarn. The yarn may be wound (and subsequently stabilised) or pass directly through a guide 23 and traverse a plate 24 similar to plate 15 but providing a shorter arc of contact with the yarn or maintained at a lower temperature, it is cooled in another air space and wound into a package 28 at a constant speed e.g. 20% less than the peripheral speed of rollers 20, 21. Treatments (a) and (b) may be effected on two separate machines. Automatically controlled plates, as at 15 and 24, or groups thereof may be combined in a single assembly (see Group XI) and may be replaced by oil-heating elements supplied from thermostatically controlled reservoirs.

Suction cups 8 3 , 8 4 , 8 5  may be movable with respect to the frame 9 rotationally via motor (11), Fig. 2 (not shown), vertically via motor (10) and horizontally via motor (12), Fig. 3 (not shown), whilst cups 8 2 , 8 6 , 8 7 , 8 8  are movable only vertically. In operation cup 8 1  descends, grips a cathode and then rises to separate the cathode from a pile on pan 2. Frame 9 is then moved to the left, the cathode is deposited on a table 3 and frame 9 is returned. Movable and stationary plates 18, 19 at right angles to each other in a horizontal plane register the cathode into position and cup 8 2  then descends, picks up the cathode and is reciprocated on frame 9 to the 8 3  position where one edge is trimmed by a guillotine 4, the following cathode being transported from the pile to the table 3. Cup 8 3  then descends, grips the cathode and orients it by rotating through 90 degrees and moving in a horizontal direction; then, upon a further reciprocation of frame 9, deposits it at the 8 4  position for trimming of another of its edges. The same happens at the 8 5  position. Suction cup 8 5  orients the cathode for trimming at the 8 8  position by a guillotine 6, the cathode being transported there by cups 8 6  and 8 7 . Cup 8 8  moves the trimmed cathode to a position where it is registered by a pusher against a stop and cut in half by guillotine 6, the halves being fed by a pusher 17 on frame 9 to a roller table 13, each half being held in a rotatable four blade gripper device 14 where they are examined prior to delivery via table 15 to a bin 16 or processing line.

Title: Apparatus for testing fluid pressure equipment
Inventor: WICKHAM DAVID JOHN
IPC: B60T17/22
Filed: 1969-04-30
Abstract: 1294683 Testing pressure vessels and pipes WESTINGHOUSE BRAKE & SIGNAL CORP 8 April 1970 [30 April 1969] 22049/69 Heading G1S A vessel or brake pipe 1 of an air brake system is connected as shown to a reservoir 9 via a check valve 4 and to a valve 5 having a seat 6 controlled by a piston 51. A gauge 10 is provided and also an exhaust choke 8. In operation air from pipe 1 acts on one side of the piston 51 and also passes through valve 4 to charge the reservoir 9 to the pressure in the pipe 1 less the check valve loading. This reduced pressure acts on the other side of piston 51. Any leak in 1 will cause the pressure to fall so that the pressure on the one side of the piston 51 will fall whilst the pressure in the reservoir 9 and on the other side of the piston will not fall because of the valve 4. The valve 6 is thus caused to open and allows 9 to vent through pipe 61 and choke 8, the pressure difference across the choke being shown on gauge 10. Eventually the pressure in 9 falls so much that the piston may be caused to close the valve 6 again and a state of equilibrium will be obtained in which the venting of 9 reduces the force on the other side of 51 at the same rate as the leakage from 1 reduces the force on the one side of 51 while the valve 6 is not fully closed. The air continuously vented from 9 will produce a steady pressure differential across 8 and thus will be registered on 10 as lb/sq.in/min and related to the leakage from pipe 1. The apparatus may be used for continuous monitoring by re-charging 9 at intervals; or modifications may be made to enable the apparatus to be used on vacuum systems.

Patent GB-588841-A (GB)
Title: Improvements in and connected with kinematograph projectors
IPC: G03B1/56
Filed: 1944-11-09
Abstract: 588,841. Kinematograph film feed apparatus. CHEESEMAN, L., and MOY, Ltd., E. F. Nov. 9, 1944, No. 22071. [Class 97 (i)] A kinematograph projector has an intermittent film-feeding sprocket arranged above the projection gate to push the film therethrough, and strain on the film is reduced by causing a pressure pad to press the film against the gate aperture during the period when the film is stationary in the gate and to move away from the film during the shift periods. Provision may be made for adjusting the film masking and for maintaining synchronism between the movement of the feed, pressure pad and shutter mechanisms during the adjustment. In one form, Figs. 1 and 3, in which the pressure pad is moved parallel to the aperture plate, the gate consists of an aperture plate 2 fixed to the projector body 1 and a front plate 3 which is hinged to the body at 4 and is held against the aperture plate by a spring-urged pin 28 engaging in a hole in a fixed quadrant 31, the gate being opened by transferring the pin to engage a second hole in the quadrant. The plate 3 carries a floating pressure pad 5, having outside the path of the film four lugs 6 fitted with pins 7 engaged by leaf springs 8, the lugs being engaged by crossconnected parallel - motion linkages 9, 10 actuated by a cam 15 on a shaft 40 driven in synchronism with an intermittent film-feed sprocket 17 to produce the desired intermittent movement of the pressure pad. The cam 15, sprocket 17 and shutter (not shown) are gear driven from a power-driven wheel 55, the cam through pinion 39 and helical gears 37, 33, the shutter by pinion 63, Fig. 6, on the cam-shaft, and the sprocket by pinion 54 actuating Maltese cross mechanism 50, 51, the mechanism being enclosed in a gear-box 62 rotatable about the shaft 52. To secure synchronism, the pinions 39, 54 and helical gears 33, 37 all rotate at the same speed. Correct masking is effected by rotating a knob 56 which through lever and quadrant gearing rotates a pinion 60 causing the gear-box 62 to turn about the shaft 52 and, in so doing, to rotate the sprocket 17 sufficiently to move the film up or down the required amount. Correct phasing of cam 15, pin-wheel 50 and shutter is maintained during the masking adjustment by causing the pinion 60, through a threaded shaft 66 carrying a fork 65 embracing the helical gear-wheel 33, to displace this wheel along the cam to which it is slidably keyed so that the shaft 40 and therefore also the cam 15 and shutter-driving gear are adjusted by an amount corresponding to that of the pin-wheel 50. In a modified form, the pressure pad is pivoted at its upper end on the hinged front plate and a barrel cam, driven and adjusted in away similar to that described above, actuates lever'mechanism to rock the pressure pad which, as before, is spring-biassed towards the aperture plate. The aperture plate in this form is provided with a yieldable lateral film guide.

Abstract: 1,193,973. Measuring fluid-flow electrically. GRAVINER (COLNBROOK) Ltd. Oct. 24, 1967 [Nov.2, 1966; May 13, 1967], No.49123/66. Heading G1N. The flow-rate of a fluid is measured by its cooling effect on the hot junction 8, Fig. 1, of a thermocouple 5, the junction 8 being periodically heated by positive pulses from an A. C. source 12, a diode 16 blocking all negative pulses, and a diode 24 preventing the positive pulses from reaching an amplifier 20 but passing the output of the thermocouple 5 during the periods between the positive pulses. A meter 22 reads the D.C. output of the amplifier indicating flow-rate, and may be replaced Fig. 2 (not shown) by a feedback connection controlling the voltage output of a magnetic amplifier 30 constituting the A.C. source for the apparatus. A meter 22 then reads the current required to maintain the hot junction 8 temperature constant, and indicates flow-rate. The diode, 24 may be replaced by a capacitor 26 the thermocouple output being pulsed. Both junctions may be situated in the fluid provided they are not thermally influenced by one another. In a further embodiment Fig. 3 (not shown) the diode 24 is replaced by a diode (44) connected across the amplifier (20) to provide a low impedance feedback path for the leading pulses, which are therefore unable to pass to meter (22). The amplifier (20) output is made zero by manual adjustment of an autotransformer (32) in the A.C. source the wiper (34) of which is geared to that of a potentiometer (38) in a D.C. circuit containing a meter (41) calibrated to read fluidflow. The potentiometer (38) is preferably a square low device, and range-changing of the meter (22) is effected by a switch (48) actuated when the autotransformer wiper (34) reaches a certain position, the switch (48) either changing the D.C. voltage supplied to the measuring circuit, or switching in a resistor (50). Alternatively, a square low cam may be geared to the wiper (34) and have a follower operating an indicater. The wiper (34) is spring-biased to return to the minimum heating position to protect the thermocouple. The device may be used to check for hydraulic fluid leaks in an aircraft and a pluality thereof may be scanned.

Abstract: In the production of monofilaments from polyvinyl chloride, vinyl chloride/vinyl acetate copolymers, vinyl chloride/vinylidene chloride copolymers or mixtures of these polymers, there is added to the polymer or polymer mixture 0,5-40% preferably 4-10%, based on the weight of the vinyl polymer or polymer mixture, of a polymer of ethylene or a copolymer of ethylene based on a major proportion of ethylene, which polymer or copolymer is incompatible with the vinyl polymer or polymer mixture.  Incompatible polymers form when mixed on a heated two roll mill a sheeted product which is cloudy when compared with similar sheets made by milling the individual polymers. In an example, 15 parts (by weight) of vinyl chloride (98%) / vinyl acetate copolymer, 81,5 parts of vinyl chloride (90%)/vinyl acetate copolymer, 6 parts of polyethylene of density 0,92 at 23 DEG  C. and melt flow index 2,0 (B.S. 2782), and 2.5 parts of dibutyl tin dilaurate (as stabilizer) are mixed and melt-spun at about 180 DEG C. to form monofilaments which are cooled to 80-100 DEG  C. in a water bath and stretched to 300% of their original length.  The monofilaments can be flagged either before or after filling into brushes by subjecting their ends to repeated blows.  Copolymers of ethylene with another alpha-olefine such as polypropylene may be used.
