Title: Improvements in or relating to advertising or display apparatus
IPC: G09F11/32
Filed: 1922-10-13
Abstract: 205,675. Shannon, J. Oct. 13, 1922. Reel and non-endless web apparatus.-An advertising apparatus comprises a series of display sheets which are attached at their upper ends to a rotatable drum j and at their lower ends to rollers 1<a> - - 12a. The spindles of the rollers 1<a> - - 12a turn in flanged sleeves n which slide in endless channels g. The spindles are provided with pinions p which engage toothed racks e while the roller is being carried upwards to wind the sheet thereon and to reveal the succeeding sheet. The rollers are raised by hooks on endless intermittent-moving chains h engaging the spindle of the bottom roller. The chains hare operated by a motor b through mutilated gearing x the toothed part of which is designed to take the chain hooks through a complete cirouit while the blank part gives the required time interval for display. The paths of the chains h and of the channels g coincide only at the display side of the apparatus, so that when each roller is taken over the drum f by the hooks it outruns the latter and falls by gravity so that it rests by its sleeve flanges n on top of the pile of rollers, partly unwinding the sheet and turning the drum f through a small angle. The lowest two rollers are each held 'by detents so interconnected that when the first roller is moved and forces its detent downwards the detent of the following roller is also depressed against the action of a spring. A bell mav be struck by mechanism combined with the detents to announce the change of picture.

Title: Condenser for textile drawing machinery
IPC: D01H5/72
Filed: 1951-11-28
Abstract: 705,039. Spinning &c machines: sliver guides. ST.. JOHN'S, TEXTILE MILLS, Ltd., and WOOD, W. J. Nov. 28. 1951, No. 27854/51. Classes 120(1) and 120(2) The fibres of a sliver are condensed by laterally spreading the sliver into an arc, exerting on the sliver a rolling action between curved surfaces, the upper surface being a ball and the lower surface being a slide, and simultaneously drawing the sliver as it travels between the surfaces. As shown, Fig. 1, slivers S from a gill can G pass over a feed roller O and through a guide U (see also Fig. 9) and are doubled by a condenser C and drafted by rollers A, B, D, E into a rove; R which is wound on to a recip-, rocating bobbin N by a flyer or traveller F. Condenser C comprises a block 13, Fig. 2, having a channel 17 of semi-circular section housing a heavy ball 16 the operative position of which is controlled by a pointed bolt 22. For insertion of slivers, the handle 26 of. a lifter 25 is depressed to raise ball 16 and back it on to an angularly-adjustable ramp 20. Lips 19 along the top of block 13 prevent the ball jumping out of channel 17. In operation, the ball is rotated, by movement of the sliver, about a horizontal axis. Owing to the low linear speed of the ball near the top of the channel, the tendency. for short fibres to be pulled out of the edges of the sliver is reduced; also owing to the shape of the ball, lapping thereof by short fibres is impossible.

Patent GB-1309134-A (GB)
Title: Electric motor control system
IPC: B66B1/30
Filed: 1970-06-12
Abstract: 1309134 Automatic speed control WESTINGHOUSE ELECTRIC CORP 12 June 1970 [30 June 1969] 28554/70 Heading G3R [Also in Division H2] A lift motor 1 is supplied from a Ward Leonard generator 3 which is driven by an A. C. motor 13, the generator field being excited by a S. C.R. amplifier 17 associated with A. C. source 19. A drag magnet regulator 21 produces a signal representing the difference between the desired and actual speeds of the lift-motor, the reference signal being derived from a pattern generator 22 which is coupled to a drum 23 rotated by tape 25. The tape is driven from the lift-car, and the  pattern generator develops a signal which varies in accordance with the distance travelled during acceleration and with the distance remaining to be travelled during deceleration. The pattern generator receives signals from controller 29 to determine the stopping-floors and to initiate acceleration and deceleration. A unit 31 indicates when the car is to run, and the unit 33 determines the direction. If the system is operating on automatic control, a circuit 35 causes network 37 to apply a bias signal to amplifier 17 to initiate movement of the car and to compensate for lag in in response of the lift to the pattern signal. A circuit 39 disables the network 37 during levelling. A hand control pattern circuit 41 positions the car at points other than level with a landing; the pattern generator 22 then being inoperative. The maximum speed on hand controls is limited by circuit 43 which reduces the potential of the A. C. supplied from source 19 to the amplifier 17. If the car receives a start signal when it is on automatic control and the car is not in a levelling zone adjacent to a floor, a synchronizing circuit 45 causes the limiter 43 to reduce the voltage of the source 19. The car operates at reduced speed and acceleration until it stops at another landing and the system is resynchronized. The car will not begin to operate if the limiter is not in its effective position. Immediately prior to movement, a signal from the circuit 45 removes the limiting signal if the car is starting from within a levelling zone under automatic control. Feedback circuits associated with the amplifier 17 comprise a stabilization network and residual suppressor circuit which reduces the loop current when the car stops. Negative feedback reduces the effect of the error signal when the car runs out of synchronization to further limit the speed and to prevent saturation of the amplifier. Since the error signal is not used when the car is operating on hand control, a feedback signal proportional to the back electro-motive force of the motor is applied to the amplifier for comparison purposes. A loop current monitor 49 detects high loop current at a predetermined time after the car has come to a stop and disconnects the A. C. source 15 from the motor 13. Power cannot be restored until the system is reset. The monitor 49 receives the stop-signal from brake 50.
