    Abstract: The number of sheets to be separated from the main output upon occurrence of a predetermined operating condition is set into a code switch. When the main output is blocked or when a predetermined number of sheets has been received at the main output, or upon application of an external signal, the contents of the code switch are transferred to a counter. Signals signifying the passage of a sheet past a predetermined location are applied to the counter and the counter counts in reverse until zero is reached. While the counter is counting a relay controlling the direction of transport of the sheets transfers sheets to a second output station. When zero is reached the relay is again energized, causing the sheets to be transported to the main output again.

    Abstract translation: 在发生预定操作条件时与主输出分离的纸张数量被设置为代码开关。 当主输出被阻塞或者当在主输出端已经接收到预定数量的纸张时，或者在应用外部信号时，代码开关的内容被传送到计数器。 表示纸张通过预定位置的信号被施加到计数器，并且计数器反向计数，直到达到零。 当计数器计数继电器时，控制纸张的传送方向传送到第二输出站。 当达到零点时，继电器再次被通电，导致纸张被再次传送到主输出。

    Abstract: The printing cylinders or other functional units of a printing machine are engaged and disengaged by positioning units. When a positioning unit receives an activating signal, its response thereto includes a dead time or delay time. Because the activation of the positioning units proceeds in dependence upon the angular position of a rotary reference component of the printing machine, and all operations are synchronized in terms of angular positions and angular spans, the dead time of the positioning units, when expressed in angular units, is a function of the operating speed of the printing machine. If the operating speed is variable, proper angular synchronization tends to be lost. The invention includes a clocked control unit clocked in angular synchronism with machine operation and determining when positioning units are to be activated and time-delay stages which introduce compensatory time delays into the application of activating signals to the positioning units. The compensatory time delays are automatically varied as a function of machine operating speed.

    Abstract: A printing machine operates at a variable speed, and includes a rotary reference component. Activation and deactivation of positioning units for printing cylinders and other functional units for the printing machine is performed in synchronization with the rotation of the rotary reference component. The positioning units exhibit dead times in their response to applied activating or deactivating signals. The duration of each such dead time expressed in terms of the extent of angular movement of the rotary reference component varies in dependence upon printing machine operating speed, tending to produce improper synchronization between activation and deactivation of positioning units, on the one hand, and machine operation, on the other hand. The speed of operation of the printing machine is monitored and employed to automatically introduce a compensatory time delay into the application of activating or deactivating signals to the positioning units, to compensate for the dead times and maintain proper synchronization.
