Class 98(2) An apparatus is described for performing the steps of charging, exposure, developing and fixing on a photoconductive layer on a backing while it is supported in one position on a plate. The photoconductive layer on its backing is supported throughout the operation on a plate 15 Fig. 1). It is precharged by moving an electrode 25 comprising wires across its surface by means of an external' operating handle. The layer is then exposed to an original 4 by means of lamps 9, 10 lens 14 and mirror 13, and the electrostatic latent image is developed with powder from a hopper 19 by rotating a roller 20 in the mouth of the hopper. Even distribution is facilitated by pivoting the plate 15 at 17 and shaking it by means of an eccentric wheel 18, which may be connected for rotation to the roller 20 and operated by a handle 21. The developed image is fused by swinging a heating element 31 from a position outside the image-forming beam to a position parallel and close to the plate 15. Different image magnifications may be obtained by swinging lens 14 about a pivot to the position shown by 16, and by placing the original 4 in the lower guides 7, 8. The charging electrode and heater may be spring loaded to return them to their inoperative positions, and contact switches may be provided to energize these devices when moved from their inoperative positions by their actuating handles.

Abstract: 1,062,862. Twisting ropes; uncoiling ropes. GEOFFROY-DELORE SOC. ANON. March 24, 1964 [April 12, 1963; Dec. 2, 1963], No. 12477/64. Heading D1T. In the known cable stranding apparatus illustrated in Fig. 1 and in which the frame 11 revolves around the cradle 15 carrying the take up reel 14 a first twisting action takes place immediately after the die 6 and a second twisting action takes place immediately after the pulley 10d. In the improved apparatus illustrated in Fig. 2 the frame 11 provides a smooth curved path for the cable 9 and, as a result, the two twisting actions now take place simultaneously at the die 6. - Fig 3 (not shown) illustrates a similar apparatus but in which a twisted core member (18) is also fed into the die 6. The core member is fed from a drum (16) carried by a floating cradle (17) and the core member (18) is supplied to the die 6 via a flyer arm (23) curved in manner similar to the frame 11. This arrangement is stated to exert no twist on the core 18 as it is fed to the die 6. Figs. 5, 6 and 7 show how the flyer frame 86 can be fitted with rollers 85 to support the cable as it passes therethrough, the rollers being preferably sloped and arranged singly as in Fig. 6 or in pairs as in Fig. 7 to assist the cable to rotate freely about its own axis as it passes through the flyer frame 86. Figs. 10 and 12 (not shown) show flyer arms according to the present invention incorporated in machines that are designed to unwind coiled cables without twisting the cables. Fig. 13 (not shown), shows an arrangement similar to Fig. 2 but wherein the cable is in free motion after it has been guided away from the axis of the die 6. The reason for this is that the ballooning effect of the free part of the cable can be used to control the speed of the machine. Excessive ballooning actuates means whereby the take up speed is reduced to a lower speed and after a predetermined interval the higher take up speed is again resumed, and so on. Avoiding tendency to untwist. The feed-out apparatus of the invention may be adjusted in such a manner as to impart to the strands or wires being fed out an untwisting effect of more than 100%; that is, the relative angular velocities are so adjusted that the strands or wires receive a degree of reverse twist exceeding the elastic limit of the wires, so that in the finished cable the strands will have a tendency to wind themselves inwards around the cable.

Title: Improvements in or relating to textile spinning and analogous machinery
IPC: D01H1/36
Filed: 1949-05-11
Abstract: 678,282. Control of several motors. HOWARD & BULLOUGH, Ltd., and HAYTHORNTHWAITE, J. J. April 19, 1950. [May 11, 1949; March 6, 1950] Nos. 12585/49 and 5581/50. Class 38 (iii). [Also in Group IX] In a textile spinning, doubling, or twisting machine (see Group IX) having three motors, one motor 13 is arranged to drive the spindles and drawing rollers, another motor 23 to drive the builder mechanism controlling the lifting and lowering of the spindle rail 4 through a heart cam 14 and epicyclic gearing and the third motor 80 is adapted to raise and lower the spindle rail 4 during a doffing cycle, during which full bobbins of yarn are removed from the spindles and replaced by empty bobbins. When spinning starts, a manual switch H is set to a position I and a starting relay SR is completed, closing contact SR(1) and opening contact SR(2). The contactors M, HF are energized to start motors 13, 23. To provide bunches of yarn on the bobbins prior to the main package formation, a bunching motion switch M is turned to "on" position before the machine is started. During rotation of the heart cam shaft 15, a detent 91 opens a limit switch D, to de-energize the contactor HF and energize contactor HR and to reverse the motor 23 until a detent 90 on a shaft 15 opens a limit switch C (C1, C2, Fig. 7) de-energizing HR and energizing HF. In this manner, the motor 23 is repeatedly stopped, reversed and re-started until the bunch has reached the desired thickness, determined by a time controlled relay TS, which opens a contact T(1) and closes contacts T (2), T(3), cutting out the limit switch D. When the package formation is complete, a detent 87 on a shaft 35 opens a limit switch B. At or about the same time, limit switch C is opened by the detent 90 to de-energize the starting relay SR and stop the motor. The circuit 23 is completed to start the doffing motor 80, which results in the actuation of a switch E (E1, E2, E3, Fig. 7) by mechanical means and the raising of the spindle rail 4 until it trips and opens a switch F, to break a circuit which includes contactors DU, M, HF, HR and starting relay SR and bring the entire machine to rest. The switch H is next set to position II, a contactor DD is energized and the motor 80 lowers the spindle rail 4 until it trips a limit switch G (G1, G2, Fig. 7), contactor DD is de-energized and the motor 80 stopped. The switch H is then set to position III to energize a contactor DU and to re-start the motor 80, which raises the spindle rails until the switch F is again tripped to stop the motor 80. By adjusting the switch H to position IV the motor 80 is started and runs until a limit switch A is actuated by a detent 86 on the shaft 35. To restart spinning, switch H is again moved to position I and the limit switches E1, E2, E3 are manually actuated. Specifications 663,198, 678,306 and 678,309, [all in Croup IX], are referred to.
