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.

Abstract: Apparatus for expelling gas bubbles from liquid adhesive which is conveyed through a conduit connecting an adhesive-containing vessel with a nozzle which applies adhesive to the running web of wrapping material in a tobacco or filter material processing machine. The conduit has a first section which contains a large-capacity pump and discharges adhesive into the enlarged portion of an annular channel defined by the cylinder and core of a gas evacuating device. The enlarged portion is followed by a second portion of smaller cross-sectional area which communicates with a radially inwardly extending gap of the core to admit some adhesive and the gases into a passage serving to return the gases and escaping adhesive to the vessel. A second section of the conduit contains a smaller-capacity pump and serves to feed degasified adhesive from the second portion of the channel to the nozzle.

Abstract: An antiskid control system for a vehicle in which acceleration and deceleration control signals are generated by a control circuit in accordance with the rotational speed of a wheel monitored by a sensor device that produces a pulse train whose frequency varies with wheel speed. A digital counter operates for the duration of each pulse cycle of the sensor signal whereby the pulse count obtained represents a cycle duration of the sensor signal. Within the control circuit to which the sensor signal is supplied, a control unit transfers the pulse count after each cycle to a first shift register as a measure of the cycle duration. The first shift register outputs the pulse count of the measured cycle duration to a comparator to which there is also connected a pulse count of a reference cycle duration supplied by a second shift register to which the pulse count of a previous measured cycle duration has been supplied by the first shift register to form the reference cycle duration.

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.
