Abstract
A hydraulic memory device has two elongated passages for liquid, an input member connected with upper ends of the elongated passages for liquid supply into the latter, and two output members each connected with a lower end of the respective passage, wherein the output members are formed so that a portion of liquid supplied in a preceding step remains in one curved output member, and during a subsequent step of liquid supply the liquid will flow into an elongated passage provided with the other output member.
Claims13
A hydraulic memory device, comprising
- two substantially upright liquid-conducting passages each having upper and lower ends;
- a liquid input member communicating with the upper ends of said passages for supplying a liquid into the latter;
- two liquid output members each connected with the lower end of a respective one of said passages so as to receive the liquid from the respective passage into the respective liquid output member and to discharge the liquid from the latter;
- and
- liquid retaining means in each of said liquid output members and formed so that if during a preceding liquid supply the liquid was flowing through one of said passages a small quantity of the liquid remains in the liquid output member connected with said one passage, and therefore with delivery of a control signal in the region of said liquid input member during a subsequent liquid supply the liquid will be flowing through the other of said passages, and vice versa, so as to provide operation of the device as a trigger with one control input and two outputs.
