<p>1,081,108. Fluid OR-gate. SPERRY RAND CORPORATION. Dec. 10, 1964 [Dec. 23, 1963], No. 50353/64. Addition to 1, 034, 366. Heading G3H. [Also in Division G4] A fluid OR-gate comprises input passages 13, 14 and an output passage 39 in which the input passages are separated by a wedge shaped member 18 which extends beyond the input passages into a chamber formed by the intersection of the output passage 39 and ducts leading to vents 51, 49. The provision of the vents prevents any build up of pressure in any one of the inputs or output when no signal is present in that one passage. A similar gate is constructed having inputs 26, 27 and an output 41. The two outputs 39, 41 form the inputs of a third gate having a wedge shaped member 44 similarly arranged to the above. The output 48 of this gate may also form one input of a further gate. The input signals 31-34 to the inputs may be applied separately or in combinations.</p> |
