Abstract: A damping valve includes a valve body with a stepped opening for receiving a preloading spring which acts on a tension rod at which is arranged a valve disk which at least partially closes a flow-out orifice of a flow channel which connects two opposite valve body sides to one another, and, in addition to the preloading spring force, a damping force which counteracts a swiveling movement of the valve disk acts on the tension rod. The additional damping force is formed by a displacer on the tension rod side. The display together with a portion of the stepped opening, forms a restrictor chamber.

Abstract: A printing apparatus for multiple signal printout has separate multiplexers for analog and pulse channels. The multiplexed analog signal is digitized, formatted, and applied via a selector to an adder, alternatively and selectively, the pulses are applied as digital signals to the adder. The adder receives zero offset numbers which differ for the different channels and the resultant numbers are applied to a one-out-of-n decoder driving printing electrodes. The system is under control of a cyclically addressed ROM whose outputs controls the multiplexing and furnishes the offset numbers. A clock sequencer times each acquisition frame.
