Abstract: 1,226,098. Shift register. TELEPHONE MFG. CO. Ltd. 11 July, 1968 [14 July, 1967], No. 32569/67. Heading G4C. An electrical binary digit handling system including at least two one-bit delay stages each including an input inverter and an output inverter and digit storage means intermediate the inverters is arranged to operate in response to the application of a cycle of four successive clock pulses to transfer an input digit through the input inverter to the intermediate storage means during the first half of the cycle and to transfer a digit from the intermediate storage means through the second inverter to the output of the delay stage during the second half of the cycle and has means for applying a first digit occurring during the first half of the cycle to the input inverter of one of the delay stages and for applying a second digit occurring during the second half of the cycle through an inverter to the intermediate storage means of the second one of the delay stages whereby both digits are transferred to the outputs of the stages by the end of the cycle. Each stage is composed of a MOS array the storage means being formed by each node capacitance. A first pulse of a four-phase clock cycle serves to charge the intermediate capacitor. A second pulse serves to enable the input inverter to discharge the capacitor if the input bit is "1" or leave the capacitor charged if the input bit is "0". During the third pulse an output capacitor is charged and during the fourth pulse the data stored on the intermediate capacitor causes discharge of or leaves charged the output capacitor. To ensure all data is transferred through adjacent stages during each clock cycle adjacent stages have data applied to their input during the successive pulses of the clock cycle. The first stage has its input applied during the first clock pulse, the second input during the second clock pulse, the third input is inverted and applied to the intermediate storage capacitor during the third clock pulse and the fourth input is also inverted and applied to the intermediate storage capacitor during the fourth clock pulse. The stages can be used in a shift register handling binary coded decimal data and can receive data from a push-button dialling system.

Abstract: 1,256,767. Feeding and delivering sheets. RANK XEROX Ltd. 8 Aug., 1969 [12 Aug., 1968 (2)], No. 39723/69. Heading B8R. A sheet feeding and delivery device for a printing machine allows printing on both sides of the sheet in a sequential manner by automatically turning over the sheet and feeding it back to a printing station after the first printing. As shown in a xerographic copier described in Specification 1,122,626 the sheets are fed from a supply station by belt 32, between pinch rollers having a register stop RS 1 to the underside of a zerographic drum 10 where a toner image is transferred, after which they pass between fuser roller 40 and roller 38 to a deflector plate 46 which sends them either to belt 42 to a receiving tray (not shown) or to guides 48, belt 50 and duplexing tray 54 from where they may be transported back to belt 32 for reverse side printing. The feeding of sheets to the tray 54 continues in a sequential manner until a predetermined number of sheets are stored therein. The sheets are counted by switch 27LS and a copy-count coincidence terminates the first stage of the operation and energizes an indicator lamp so that the operator may substitute the original for printing on the second side. When the operator presses a button copy sheets previously held away from belt 58 by fingers 56, which are retracted, are lifted by belt 58 with the co-operation of pivoting finger 60 to pinch rollers 62, 64 and 68, 70. The tripping of switch 27LS by the first sheet separates rollers 68, 70 and places stop fingers RS-2 in the sheet path to stop and align the following sheet which proceeds further only when a switch 36LS, Fig. 3 (not shown), on a cam bank is actuated. Switch 27LS also removes power from belt 58 and lower pinch rollers 62, 64 so long as the succeeding sheet has tripped a switch XLS.
