<p>1,165,503. Fluid oscillators; pulse shapers. HONEYWELL Inc. March 18, 1968 [March 16, 1967], No. 13084/68. Heading G3H. A fluid control device has means for generating pulses at a frequency determined by a first parameter, e. g. the speed of a turbojet engine, a pulse shaper which determines the duration of these pulses in accordance with a second parameter, e. g. the temperature in the engine's air intake, and an integrator which registers a pressure proportional to the product of the frequency and duration of the pulses. A shaft 21 connected with the engine's compressor shaft, rotates a notched disc 23 arranged to interrupt the flow to a receiver 26 of air at intake temperature issuing from emmitter,25. A mono-stable switch 41 biased to outlet 45 receives these pulses at its control parts 43, 44 via different length pipes 35, 36 at timed intervals which are determined by the temperature of the air. Thus the higher the air temperature, the shorter the duration of the pulses fed from outlet 46 to capacitor 50 the pressure in which is communicated to an acceleration control 54.</p> |
