Title: Improvements in automatic telephone pay station
IPC: H04M17/02
Filed: 1920-10-06
Abstract: 178,141. Long, G. A. Oct. 6, 1920. Hiring telephone apparatus.-A coin-freed substation equipment is provided with coin-operated means for rendering the telephone, and calling dial (automatic exchange) operative, and means whereby coins or other tokens of different value transmit different signals to an exchange operator. To render the telephone and the dial operative, a coin must first be inserted in the aperture 12, Fig. 1, at the top of the shoot 8, Fig. 3, and as the coin drops into the hopper 23 it operates a trip which acts upon a spring, which in turn operates other springs to remove a short-circuit from the impulse springs of the dial 18, and either close a point in the telephone circuit or remove a short-circuit across the telephone. When a toll-line call is required, the operator instructs the calling party to insert further the required amount. Coins of different values inserted in the apertures 12, 13, 14, Fig. 1, pass down the respective shoots 8, 9, 10, Fig. 3, which are so arranged that a coin in the shoot 8 strikes a bell 15 once, a coin in the shoot 9 strikes the same bell twice, while a coin in the shoot 10 gives a single stroke on the gong 16. These signals are transmitted to the exchange operator by their effect on the transmitter 6. Fig. 1. The return or collection of the coins may be effected in known manner.

Title: Apparatus for cleaning the pins and brushes of varied types of machines for treatingfibres
IPC: D01G19/22
Filed: 1939-10-23
Abstract: 535,857. Preparing fibres ; cleaning machines. FAIRBAIRN LAWSON COMBE BARBOUR, Ltd., FAIRBAIRN, M. H. WAILES-, [Representative of FAIRBAIRN, N. W. F. WAILES-.] Oct. 23, 1939, No. 28443. [Classes 120 (i) and 120 (iii)] The rotary brush of a machine for the treatment of fibres for spinning is cleaned by a pinned bar or comb which is automatically moved towards the rotating brush so that the pins enter the brush and remain in contact therewith for a sufficient time to remove any material clogging the brush, the bar or comb then being automatically moved out of contact with the brush and, when clear of the brush, a perforated stripper plate being automatically moved along the pins of the bar or comb to push the material cleaned from the brush off the pins and being subsequently automatically moved back along the pins before they again engage the rotating brush. As shown the rotary brush of a push-bar gill drawing frame for jute is cleaned by pins L on a bar K fixed to brackets J on a shaft B which is slowly rotated by worm gearing from the faller shaft H ; a perforated plate M slidably engaging the pins is carried by guide rods N slidable in lugs on the brackets J, one of the rods carrying a runner P adapted to engage a cam plate R fixed to the machine frame. As the shaft B rotates, the pins L, with the plate M engaging their bases, enter the bristles of the bush and remove therefrom any material clogging the bristles and when the pins leave the bristles, the runner P engages the cam plate R and the plate M is forced outwards along the pins to remove the material thereon and,.after the runner has left the cam plate and the pins reach the vertical position pointing upwards, the plate M falls to its inward position ready for the pins again to engage the brush bristles. In a modification the pins are carried by a pivoted arm linked to a pivoted lever which is oscillated by a slowly rotating cam and the perforated stripper bar has runners engaging curved slots in fixed plates.

Title: Improvements in and relating to photographic cameras and shutters
IPC: G03B7/083
Filed: 1965-07-06
Abstract: 1,037,599. Photographic shutters. AGFAGEVAERT A.G. July 6,1965 [July 9,19641, No. 28588/65. Heading G2A. The everset shutter assembly of a photographic camera is shown in its tensioned position. To effect an exposure, a lever 27 is rotated in the direction f, thereby rotating a pawl 32, which in turn carries a first blade ring 10, by way of a pin 35, in a direction opposite to e, a second blade ring 11 being constrained to move in the same direction. Rotation of the rings tensions springs 18, 20 and a cam 52 closes a switch 51 allowing current to flow in the circuit 36 to charge a capacitor 50 and energize a relay 40. After a short time the relay responds, pivoting a pawl 41 into the running down path of an abutment 43 of the ring 11. Continued rotation of the rings allows a projection 46 to close a switch 38 before the cam 52 opens the switch 51. After tensioning is finished the pawl 32 escapes from the pin 35 allowing the ring 10 to run down under the action of the spring 18, escapement retard mechanism 22-25 causing it to run down evenly. Running down of the ring 10 opens the switch 38, but de-energization of the relay 40 is delayed by the discharge of the capacitor by way of the photo-resistor 39. De-energization of the relay 40 swings the pawl 41 out of the path of the ring 11 allowing it to run down. When the lever 27 is released, it is urged by a spring in a direction opposite the direction f into contact with the lower end of slot 29 and the pawl 32 slides past the pin 35 and falls into place behind it. Two or more pivoted shutter blades are provided to be controlled by the rings 10, 11. In another embodiment (Fig. 2, not shown) the second switch 51 is actuated by a control cam 52 on the lever 27.

Title: Pulse transmission systems
IPC: H03M7/00
Filed: 1972-06-20
Abstract: 1348470 Delta modulated pulse transmission WESTERN ELECTRIC CO Inc 20 June 1972 [21 June 1971] 28723/72 Heading G4H In a signal transmission system, the presence or absence of pulses at predetermined, periodically occurring positions of a delta modulated pulse train is determined and the size of the increment or decrement to the reference voltage is modified to a predetermined fraction of its usual value. This permits a reduced sampling rate for the same signal to noise ratio. As shown, an input analogue signal is fed to comparator 20 and is compared with the voltage on capacitor 28. The output ("1" when the applied voltage is greater) is gated by a clock pulse on line 23 into flip-flop 22 and the "1" output of the flip-flop is fed to integrator 27, which, when enabled by a clock pulse which is delayed at 15, increases the charge on capacitor 28 by Q. When there is no "1" input the charge is reduced by Q. Clock 13 also supplies a counter 31 which counts up to 2<SP>N</SP>-1. The counter has outputs at 0, 0 to 2<SP>N</SP>-2 and 2<SP>N</SP>-1. A second counter 30 is supplied with "1" pulses by gating at 29 the clock output and the "1" output of flip-flop 22, while counter 31 counts from 0 to 2<SP>N</SP>-2. When the count of 2<SP>N</SP>-1 occurs in counter 31, gate 29 is closed and gate 34 enabled, the state of flip-flop 22 being set into flip-flop 39. This produces, from integrator 42 a charge Q/2 of opposite sense to that being supplied by integrator 27 so that the net change on capacitor 28 is only Q/2. At the same time, the contents of counter 30, which represents the number of "1"s in 2<SP>N</SP>-1 positions of the delta modulated train is transferred to shift register 37 ready for transmission.
