IPC: H03K3/78
Filed: 1969-10-07
Abstract: 1278945 Pulse pattern generation BRITISH AIRCRAFT CORP Ltd 6 Oct 1970 [7 Oct 1969] 49187/69 Heading H3P [Also in Division G4]  A pulse pattern is generated by progressively filling from a clock source first and second registers which are initially partly filled, resetting the first register, when full, to its initial partly filled state while the supply of clock pulses to the registers is momentarily interrupted and terminating the clock supply when the second register is full, the output pattern being derived by logic circuitry from the first register. In response to "address 1" a register 2 is partly parallel filled from register 1 which was prefilled by "address 4" and register 3 is partly parallel filled by "address 5". In response to a start command a bi-stable circuit B1 is set and clock pulses step up the registers. When register 2 is full a mono-stable circuit M1 produces a pulse which operates an OR gate G1 to cause the register 2 to be refilled to its original initial value, the mono-stable pulse via line 10 also blocking the clock supply while refilling is effected. The repeated filling of register 2 continues until register 3 is full, whereupon its output resets B1 to terminate operation. The outputs of the. register 2 stages (Fig. 2) are applied to AND gates together with the outputs of bi-stables B3-B6 which are preset in accordance with the desired output pulse pattern. The AND gates control start and stop gates which in turn control a bi-stable circuit B2 supplying the circuit output. The pattern can be varied by varying the logic and the prefilling of the registers. In addition, further registers such as 1 and 2 may be provided.

A suction drum for separating sheets from a stack or for removing selected sheets from a continuous stream and placing them in a stack, consists of a hollow rotary drum, the cylindrical wall of which is formed with at least one opening, a valve within the drum and adjacent said opening, cam means for moving the valve to connect or disconnect the opening and hollow interior, and suction means connected to the hollow interior. The suction drum is hollow and has two sets of apertures 51a and 51b in its curved wall. Said wall is formed with housings 41a and 41b on its inner surface adjacent the apertures 51a and 51b. The housings are provided with apertures 57a and 57b and contain rotatable valves 58a and 58b. The valves consist of tubular members having slots or apertures 55a anf 56a, whereby in one position they place the respective apertures 51a and 51b in communication with the interior of the drum and in a second position block off the apertures from the interior of the drum. A suction pump 28 is connected to the interior of the drum. Each valve has a cam follower 60a or 60b, offset from the axis of the valve and urged by springs 63a and 63b towards a circular cam surface 67. The lower face of each valve is extended to form a lug 80a or 80b, Fig. 5. A spring-pressed latch 75a, 75b is associated with each valve whereby the valves are normally latched in their aforementioned second positions with the cam followers clear of said cam. Each latch is pivoted to the underside of the drum and is lifted by a solenoid 84, to release the corresponding valve, when it is desired to pick up a sheet. In a second embodiment, Fig. 6 (not shown), the valves are reciprocably mounted in said housings and spring- urged downwardly towards a cam surface. The valves are normally latched in their uppermost position with their cam followers clear of said cam surface. In this position the suction is cut off from the apertures 51a, 51b. Again, the latches are released by a solenoid when it is desired to pick up a sheet. As applied to stacking apparatus, a stream of cheques is delivered from data-processing equipment by a single endless belt 12 and a plurality of cooperating belts 13, Fig. 2. Each belt 13 passes around a rotating suction drum 15, running in a groove 20 in the surface thereof. On receiving a signal from the processing equipment, the solenoid 84 is operated to apply suction to a set of openings 51a or 51b in the drum and remove a cheque from the stream and deposit it on a stack.
