    摘要： A summing arrangement is described in which numbers represented by binary signals are summed by using threshold devices. The threshold devices each have a plurality of inputs which are connected to receive the input signals. Since all the threshold devices have different threshold criteria, the number of threshold devices energised will vary in accordance with the number of signals present at the inputs and thus provide an indication of the sum of the signals received. Logic circuits are then used to convert this information into a binary output. The threshold devices can comprise fluidically operated devices.

    摘要： An operator''s control lever which is shifted to actuate a hydraulic motor is returned to the initial position to stop the motor after a preselected amount of travel of a element driven by the motor. A fluidic circuit has means producing digital signals indicative of successive increments of travel of the element and has a counter for storing any preselected number of such signals. When the selected count is reached, a kickout means manipulates the operator''s control lever to stop further operation of the motor. The count required to stop the motor, and thus the amount of travel of the element, may be changed by turning of a control knob. The system is applicable, for example, to limiting movement of the lift arms of a loader vehicle.
