    Abstract: An arrangement in multiple color rotary printing machines for controlling the stacking of sheets so that they are stacked on either of one of two stacks. One stack is designated for normally processed sheets, and the other stack is designated for those sheets different from the normally processed ones. A shift register is actuated with shifting pulses from a pulse generator, and receives a signal from a sheet examining station in one stage of the register. A memory circuit is connected to this one stage of the register. The output of the memory circuit actuates, through an amplifier, a stacking mechanism so that the distribution of printed sheets is controlled between the two stacks.

    Abstract: An arrangement for controlling the operation of multiple color printing machines adapted for printing on material in sheet form. A shift register has its output stages connected to sampling circuits which control the on and off operation of the machine in dependence on the information contents of the shift register stages. A sheet sensing station detects the position of a sheet of material and transmits the corresponding information into the shift register which is shifted by clocked signals at predetermined instants in the machine operation.

    Abstract: A detecting capacitive structure undergoes changes in capacitance value depending upon whether it is detecting, in the sheet transport path of a printing machine, a normal or single sheet, an absent sheet, or a double or stuck-together sheet, so that corrective action can be initiated, such as the skipping of a printing cycle. The detecting capacitive structure and also a reference capacitive structure constitute the capacitances of two RC circuit stages to which an input signal is applied and then removed. The variations with respect to time of the output signals from the two RC circuit stages are then compared, both during application of the input signal and subsequent to removal of the input signal. This comparison of time responses of the two RC circuit stages serves as the basis of the detection. The effect of the normal, absent or double sheet upon capacitance value is detected by monitoring a response dependent upon the time-constants of the RC circuit stages, without the detecting capacitive structure forming the capacitor of or resonant circuit.
