Filed: 1966-11-21
Abstract: 1,166,286. Change speed gear. TOYODA AUTOMATIC LOOM WORKS Ltd. 21 Nov., 1966, No. 52041/66. Heading F2D. [Also in Division D1] Apparatus for returning the cone-belt in a flyer frame at the end of a spinning-operation, comprises a differential gear having one input side and two output sides; connected to one of the output sides are means to slacken and tension the belt, and to the other, means to actuate a belt-shifter, while means are provided for driving the input side in two opposite directions. The belt 2 is slackened and tensioned by raising and lowering the lower cone 1<SP>1</SP>. To this end, it is carried by two racking-arms, one 13 of which has a thread engaged with the threaded end of a rotatable shaft 11. To move the belt along the cones it is connected at 10 to a rack 9 engaged by a gear 8 on a shaft 6 also carrying a pulley wrapped by a cord with a counterweight 7. In known apparatus, the shafts 11, 16 are operated by separate handles 12, 27. To avoid the inconvenience so arising, both shafts are adapted to be driven by a single handle 24 or a motor M through a differential. The handle or motor rotates a worm 14 meshing a worm-wheel 15 carrying the input bevel c meshing upper and lower bevels d, a. These are loose on a shaft 16 and the upper bevel is connected to a pulley 19 also loose on the shaft which is connected to a pulley 16<SP>1</SP> also loose on the shaft 16 which is connected to a pulley 18 to drive the rack-pinion shaft 6. The belt is shown in the position it assumes on the cones at the end of a spinning operation. It is now necessary to move it to the other end of the cones so that a new spinning-operation may start. It is first necessary to slacken the belt; this is done by rotating the worm-shaft by a handle 24 or the motor M so that the upper gear d is rotated to drive the shaft 11 through the pulleys 19, 21. During this operation, the bevel a connected to the rack is not driven since it is loaded by the tension in the belt and the counterweight 7. When the belt is slack part of this load is relieved and the bevel a is freed to rotate the rack-pinion 8 through the pulleys 16<SP>1</SP> and 18, further rotation of the shaft 11 being prevented by a stop 22. When the motor M is used, it is stopped by automatic means. If is now necessary to lower the cone 1<SP>1</SP> to tension the belt; for this, the direction of rotation of the handle 24, or the motor is reversed, the bevel a and pulley 16<SP>1</SP> being stopped from rotating by a ratchet-wheel 25. To move the belt along the cones during spinning, a ratchet wheel 3 is rotated a step at a time to drive the shaft 6 through gears 5 and a clutch 28 which is disengaged during the above described operation and is controlled by a solenoid 29.

Patent GB-528212-A (GB)
Abstract: 528,212. Actuation of switches GARDNER, H. May 1, 1939, No. 12939. [Class 38 (v)] A cam 6 is driven by a motor 4 so as to rotate once every five'minutes, say, and engages an arm 7 urged there-against by spring 9 and pivoted on spindle 8. Also pivoted at 8 is a platform 10 carrying a tilting mercury switch, which platform is urged by spring 14 and lug 13 bearing on arm 7, to follow the movements of the arm, but is normally retained in raised, " off," position by a detent 36 on an arm 35. At each revolution of spindle 5, an arm 25 engages one of twelve pins 24 on a disc 23 which is fast on a spindle 23 carrying a sprocket drum 15, the latter being thus rotated once every hour. A closed band 16 of kinematograph film driven by the drum 15 bears markings 19 representing a 24-hour period in 5- minute graduations, and has two rows of perforations 26, 26a co-operating respectively with pins 27, 27a on levers 28, 28a, which are pivoted at 29 and urged by springs 30 so that the pins 27, 27a bear on the film 16. Further pins 43, 43a on levers 28, 28a co-operate with two rows of holes on a day drum 40, there being five holes in one row corresponding to "Monday "to " Friday respectively, and two holes in the other row corresponding to " Saturday" and " Sunday." Drum 40 is rotated about spindle 44 by means of a toothed wheel 50 which, at the end of each day, is engaged by the turned-up end 47 of a bell-crank 45 on the disc 23. Normally the end 47 is retained by the film in a slot 48 in the drum 16, but in the position shown in Fig. 6, a slot 49 in the film comes level with slot 48 and the weighted end 46 of lever 45 causes the end 47 to move out of the slot 48 and engage one of the teeth to advance the wheel 50 by one day. An arm 33 carrying arm 35 is pivoted at 33a and urged by spring 34 so that its free end bears on the under sides of levers 28, 28a. During weekdays, the arm 28a is inoperative, and both arms 28, 28a are held raised by engagement of the fingers 31 by the high part 32a of a cam 32 while the pin wheel 23 is being moved on. When a perforation 26 or 26a comes under pin 27 or 27a and the finger 31 of lever 28 or 28a slips off the cam-part 32a, the lever 28 or 28a depresses arm 33 and detent 36, so allowing the platform 10 to follow the arm 7 and close the switch. When the arm 7 moves off the high part of cam 6 it is lifted by its spring, raises platform 10, and opens the switch. Meanwhile the cam 32 has again lifted arm 28 or 28a, so allowing arm 33 to restore the detent 36 and retain the switch " off." The fingers 31 are a friction-fit on their pivots so that they can be moved to advance or retard the tripping of the switch and hence vary the period of closure thereof. An indicator 53 on the drumspindle 22 bears markings showing the minutes of the hour in five-minute graduations which are visible through a hole 24 in the casing.

Abstract: 1,165,428. Cine cameras; control devices. NIPPON KOGAKU K.K. Nov.21, 1967 [Nov.22, 1966], No.52899/67. Heading G2E. An automatic control device for taking-up and re-winding film in a cine camera to permit double exposures to be made, comprises a scale gear 16 which may be connected to the film feed driving shaft 1 through a clutch gear 6 shiftable on sliding plate 8 by means of cam 11, the gear 16 then being rotated against spring 20 until pin 18 trips a switch 21 which stops the camera motor, the direction of rotation of the motor and hence of gear 16 being controlled by manually set switch 12. When clutch gear 6 engages scale gear 16, on setting dial 13 to W, the film take-up shaft is not driven since take-up gear 4 is disengaged, but the film-feed operates to drive film loosely into a recess in the take-up chamber from which it is re-wound when the motor is reversed by switch 12 when dial 13 is set to R. In resetting dial 13, gear 6 is momentarily disengaged from gear 16 which then returns to rest due to spring 20. The position of switch 21 relative to gear 16 is such that the gear 16 rotates through a smaller angle during re-wind than during the W motion breakage of film is thus avoided. The second exposure may then be made.

Filed: 1971-11-15
Abstract: 1368637 Escape shoots B F GOODRICH CO 15 Nov 1971 [16 Nov 1970] 52967/71 Heading B7J An escape slide positioning tube 10 comprising an inflatable hollow body of flexible foldable material is disposed under inflatable longitudinal tubular members 30, 31, 35, 36 and 37 of an escape slide 11, near the end of the slide attached at 16 to a supporting structure such as an aircraft 12, so that inflation of the tube 10 will bias the slide 11 to a desired direction and inclination relative to the supporting structure. The tube 10 is of a cord-reinforced rubberlike material and is cylindrical when inflated, having part of its cylindrical wall attached to the underside of the slide 11 and its ends 27, 28 extending transversely beyond the slide to increase the stability of the slide by contact with the wall of the aircraft 12. The deflated tube 10 and slide 11 are stored as a compact package until required when, in the case of an inflatable slide 11 as shown, the tube 10 and slide 11 are ejected with the slide in a partially extended position due to fastening means 19, 20. Air pumps 24 at the upper end of the slide 11 start to inflate the slide and quickly inflate the tube 10 which communicates with the interior of the slide 11  via openings 39, 40, Fig. 5. Thus the position shown in Fig. 3 is reached in which tube 10 is fully inflated, and slide 11 is partially inflated and partially extended. As the pump 24 continues to operate, the increasing pressure causes the fastening means 19 and 20 to become disengaged and the slide extends to meet the ground 13, as shown in Fig. 1. The fastening means 19 and 20 may comprise co-operating pairs of members 47, 48 and 49, 50 secured to the slide 11 at longitudinally spaced positions, each member consisting of a fabric having stiff, hooked fibres (51), Fig. 6 (not shown), extending outwardly for engagement with those of the opposing member.
Patent GB-529820-A (GB)
Abstract: 529,820. Yarns. TAYLOR, W. I., GIBBINS, L. B., and BELL, A. S. June 9, 1939, No. 16857. [Class 120 (iii)] In forming a yarn containing staple fibre from a bundle of continuous filaments, the bundle is passed through an abrasive tube which forms a balloon guide of a downward twisting apparatus and the package on which the yarn is collected is rotated at a speed which diminishes as the package builds up so as to maintain the size of the balloon and the degree of cutting action of the tube on the filaments substantially constant. As shown, two yarns 1, 2 are doubled together, the yarn 1 passing between a pair of feed rollers 5 to a guide rod 9 and down through a slotted member 10 where the yarn 1 joins the yarn 2 fed by a pair of rollers 7, driven at a lower peripheral speed than the rollers 5. The member 10 is mounted on an adjustable arm 11 pivoted on the rod 9 and from the slot in the member the yarns pass through the tube 19 of abrasive material to the ring and traveller spinning device 17, 18 where the yarn package is collected on the tube 12. Since the yarn 1 is fed faster than the yarn 2 it forms a loose spiral around the yarn 2 and the cutting action of the tube 19 is exerted on the filaments of the yarn 1 and not on those of the yarn 2; the composite yarn may be doubled with a further yarn, preferably of continuous filaments. As the yarn builds up in the tube 12 of the ring spinning device, the size of the balloon 23 and the cutting action of the abrasive tube are kept constant by driving the spindles 13 through an infinitely variable gear box so that the speed thereof may be diminished continuously throughout the twisting operation. According to the Provisional Specification the abrasive tube may be driven in the same direction as, or in the opposite direction to, that of the balloon and at any desired speed. Specifications 397,138 and 399,838 are referred to.
