Title: Improvements in apparatus for twisting wires together
IPC: D07B3/06
Filed: 1929-03-19
Abstract: 330,660. Callender's Cable &. Construction Co., Ltd., and Allcock H. J. March 19, 1929. Cables, machines, apparatus, and processes for making.-In a machine for twisting together a pair of wires in sudden separate steps, Fig. 5, as distinguished from a, uniform spiral twist, the untwisted wires are passed from a bobbin frame through a guide member adapted to perform a rotary step-by-step movement which is affected by a mutilated gear wheel. In the embodiment shown, the machine is arranged to operate on two pairs of wires simultaneously. Discs 1, 39, Fig. 7, attached to a shaft 2, carry bobbin frames 37 which are connected to pinion wheels 4, Fig. 1. by hollow shafts 3 passing through the disc 1. The motion of the pinions 4 is transmitted through gearing 5, 8 to mutilated gear wheels 10 which rotate the tubular wire-guides 19 in a series of steps by means of gear wheels 13, 15, 16. In order that the guide members 19 shall always turn through the same angle, the mutilated gear wheels are formed with ribs 29 between the sets of teeth, adapted to engage grooves in certain teeth of the wheels 13 and to lock the latter in position after they have turned through their proper angle. The locking action may be further assisted by blade springe having tongues which engage recesses in sleeves 36 of the wheels 13. When the machine is in operation, the wires pass from bobbins 38 through the hollow shafts 3 and guide members 19 to pulleys 20 situated near the ends of the guide members-. Each pair of wires takes a number of turns around its pulley and then passes to a take-up drum. A train of wheels, not shown, but carried on the disc 39 causes the bobbin frames 37 to revolve about their axes when the shaft 2 is rotated, and a uniform twist is thus given to the wires between the bobbins and the toothed wheels 16. The uniform twist is taken out periodically by the sudden rotation of the guide members, which are adapted to revolve at the same average speeds and in the same direction as their respective bobbin frames, and a sharp local twist is imparted to the short length of the wires between the guide members and the pulleys 20. In a modified construction flat plates are substituted for the pulleys 20. The machine when used in conjunction with a quadding die can be arranged to form a quad of telephone wires; by rotating the two bobbin frames at different speeds, each of which is different from that of the shaft 2, the two pairs of wires are given different lays, each of which differs from the lay of the quad.
Patent GB-1101243-A (GB)
Title: Improvements relating to the cross-winding of endless synthetic yarn
IPC: B65H54/42
Filed: 1965-03-02
Abstract: In the winding of a large compact package of synthetic yarn, the package is peripherally driven by frictional contact with a driving roller whose speed is increased during the winding operating by about 2-3.6% to counteract both the increase in slippage between the roller and package during winding and the fact that the ends of the package become of larger diameter than the rest of the package, so that the yarn is wound at a constant speed.  The speed of the driving roller may be increased in dependnce on the package diameter, or through a time switch, or in dependence on the yarn tension, by changing the frequency or the field current of the electric driving motor of the roller.

Title: Improvements in and relating to helicopter unsafe landing gear warning system
IPC: B64C25/28
Filed: 1966-03-01
Abstract: 1,142,541. Undercarriage warning devices. UNITED AIRCRAFT CORP. 1 March, 1966 [24 March, 1965], No. 8966/66. Heading B7W. In a helicopter a warning device to warn a pilot if an undercarriage member is not fully locked down comprises on each undercarriage leg respectively a switch 26, 28, 30 which is open when the respective leg is down and fully locked. When closed any switch will energize solenoid 32 to close switch 34 to transmit a 28 V supply on line 36 through a switch 38, which is closed by solenoid 40 when a radar altimeter 22 is switched on, to a normally open switch 42, which when closed will connect to a normally closed switch 44 to energize a visual and aural warning device 24. Switch 42 is closed when a signal indicating that the radio altimeter is unreliable de-energizes relay 50 to open switch 52 thereby de-energizing solenoid thereby permitting the 28 volt source to energize relay 56 and close switch 42 to give a warning that the altimeter reading is unreliable. Altimeter 22 delivers a signal over line 66 to comparator 70 which provides an output whenever a signal representing instantaneous altitude is less than a signal of predetermined altitude derived at 74. The output energizes solenoid 80 to close normally open switch 82, and when normally earthed switch 52 is operated by solenoid 50, in response to a signal on line 81 that indicates that altimeter 22 is switched on and functioning, relay 56 is energized to close switch 42 and operate warning device 24 to indicate that the helicopter is below a predetermined altitude with an undercarriage leg unlocked. If the pilot does not intend to land he can turn off the warning signal by a switch 90 that energizes a clutch 20 associated with the collective pitch adjusting lever 23, so that should he later bring the helicopter below the predetermined altitude the warning system will be re-activated.

Abstract: 864,419. Automatic tension control systems. GENERAL ELECTRIC CO. Ltd. March 24, 1959 [March 24, 1958], No. 9325/58. Class 38 (4). In a web-feeding arrangement, the sag in a catenary is maintained constant by controlling the tension in the web in dependence on the weight per unit length of web and the force required to produce the tension in the web. As shown, a metal strip 1 passing through a sequence of pickling baths 2-4 hangs in a series of catenaries over guide rollers 5-10. A free loop of constant sag is maintained between guide rollers 9, 10 and further guide rollers 12, 13 by a system responsive to photo-cell arrangement 14. Rollers 9, 10 are driven by a motor having constant field excitation, the armature 15 being supplied from an armature 17 of a Ward-Leonard generator so that the voltage across a resistor 19, in series with the armature 15, is representative of the torque of rolls 9, 10. The force acting on a roller 8 due to the weight of the web is sensed by a transducer 18, the output voltage of which is applied to a magnetic amplifier 20 in opposition to the voltage across the resistor 19. The magnetic amplifier 20 controls a field 21 of a series booster 22 to vary the current to an armature 16 of motor driving rollers 5, 6 so as to maintain the sag in the catenaries constant.
