[Class 100 (i).] Pile supports.-In order to renew the pile of sheets quickly in a sheet-feeding mechanism, the frames d, which support sprockets n for actuating chains n<1> which raise the active pile p, are extended to form supports for additional sprockets i<1> and chains i which support a new pile p<1> above the active pile. The piles p, p<1> are registered against vertical walls w, w<1> which are in vertical alignment so as to prevent damage to the edges of the sheets when the top pile is lowered. To prevent the pile p<1> from being lowered at a time when it could damage the sheet-separator u, this separator is caused to operate a lever s connected to a sliding rod v which is moved to engage between the teeth of the sprocket i<1> whenever the separator is underneath the pile. The rod v terminates in a spring pawl which can yield if it strikes one of the teeth instead of engaging in a gap between two teeth. It then engages between the teeth on a slight rotation of the wheel.

Title: Circuit arrangement for storing and retransmitting data received in the form of electric impulses
Inventor: BAGGOTT ALBERT JEFFERIES
IPC: G11C11/28
Filed: 1957-10-08
Abstract: 827,041. Counting-apparatus. LANDIS & GYR Ltd. Oct. 8, 1957, No. 31500/57. Addition to 822,331. Class 106 (1). The circuit described and claimed in the parent Specification is modified so that the storage device cannot be primed twice by a signal of prolonged duration and is further modified by connecting the counter coil associated with each storage device in the cathode circuit of the second cold-cathode tube instead of in the grid circuit of the first cold-cathode tube. The arrangement described is generally similar to that of the parent Specification in which pulses from a plurality of transmitters are temporarily stored and the stores are sensed by an electronic switch so that an output pulse is sent to a totalizer from each store which has received a pulse. Alternating pulses passing, for example, to a store B1 over a line 3 are effective during their positive half-cycles to fire a tube V1 and thereby prime a tube V2 only if grid potential of V1 has been raised sufficiently by an associated circuit comprising a condenser C8 and resistance R12. A pulse from the electronic sensing switch C which senses the stores cyclically then passes via the condenser C2 to fire the tube V2 if it is primed, thereby actuating the associated counter coil L1, discharging the condenser C8 and cutting off the tube VI. The output pulse passes to the summating arrangement D and energizes the coil of a totalizing counter L2. Due to the relatively long time constants of the circuits R12-C8, one of which is provided for each store, a lengthened input signal cannot give rise to more than one recorded pulse since if such a signal is prolonged beyond the cut-off of V2, V2 cannot be primed by a second firing of V1 since the grid of V1 will not have attained priming potential. Sensing pulses of a desired frequency may be mains frequency or a harmonic thereof, or may be provided by an oscillator.
