Abstract

1,264,762. Fluid pressure actuated switches. WORTHINGTON CORP. 30 Jan., 1970 [25 Feb., 1969], No. 4582/70. Heading H1N. [Also in Division F1] Electric switches 70, 76, Fig. 5, are actuable under the control of a bi-stable fluidic element 12, the output lines 20, 22 of which are coupled to a pair of diaphragm actuators 58, 62 having a mechanical connecting member 50, 52, whereby as fluid is introduced into one actuator (as 62), fluid is forcibly vented from the other actuator (as 58). The couplings are made to fixed rigid pans 56, 60 mounted on a frame 48 and carrying the link member 50, 52 in a slot 66 through which a locating third arm 64 extends.
