Abstract: 1,260,487. Fluidic devices. NATIONAL RESEARCH DEVELOPMENT CORP. April 30, 1969 [May 20, 1968], No.23974/68. Heading G3H. A fluid control device comprises a chamber B connected to a chamber A through a construction D, liquid L in the chambers, a control gas supply S connected to chamber B, and a fluidic circuit U connected to chamber A; the arrangement being such that when gas is supplied to chamber B it first displaces all of the liquid in to chamber A and then, by bubbling through the liquid, supplies control gas to circuit U. The device can be used as a delay element in either a negative feedback oscillator Fig.3 (not shown) or a pulse generator incorporating logic circuits Fig. 4 (not shown). A valve, e. g. ball V, can be provided to produce easy flow in one direction only, to increase the time constant of the device.
