Abstract
1,193,786. Pure fluid amplifiers. GENERAL ELECTRIC CO. Feb. 9, 1968 [Feb. 28, 1967], No.6606/68. Heading G3H. The gain of a pure fluid momentum exchange amplifier 5 is varied by adjusting the steady bias pressure P B acting in opposition to a varying control pressure P 01 on the constant pressure power stream issuing from nozzle 9 into amplified signal receiver 10 so that the amplifier operates on the desired part of its input/output curve Fig. 3 (not shown). As shown a pair of indentical push-pull connected analogue amplifiers 5, 6 are vented at 28-31 and have bias control nozzles 23, 26 and power nozzles 9, 19 fed respectively from common sources P B , P S . Specification 1, 141, 019 and 1,193,785 are referred to.
