摘要： Methods and apparatus utilize a rate of drop in pressure upstream of a gas flow controller (GFC) to accurately measure a rate of flow through the GFC. Measurement of the gas flow through the many gas flow controllers in production use today is enabled, without requiring any special or sophisticated pressure regulators or other special components. Various provisions ensure that none of the changes in pressure that occur during or after the measurement perturb the constant flow of gas through the GFC under test.

摘要： PCT No. PCT/US79/00968 Sec. 371 Date Nov. 8, 1979 Sec. 102(e) Date Nov. 8, 1979, PCT Filed Nov. 8, 1979An improved load resolver (41) is provided of the type which receives a pair of generally unequal pressure signals (32, 34), and which resolves the pair of pressure signals (32, 34) by blocking the lesser and transmitting the greater. Each pressure signal (32, 34) is sent to the load resolver (41) by a respective control valve (18, 20) in a hydraulic system (10). Prior load resolver structures have required angled or intersecting holes therein or special porting therearound. The improved load resolver (41) comprises a first member (58) having a first, axially extending hole (64) and a second member (72) having second and third axially extending holes (78, 104). The members (58, 72) are fitted within a bore (48) of a control valve body (19). The improved load resolver may be utilized in a load resolver system (114) having stackable control valve bodies (17, 19, 21) without the need of special porting therebetween.

Means is provided for actuating the timing device in response to a relatively short-term activating pulse.

摘要： An instantaneous signal applied to the inlet of the timing device is passed through a restrictor into a capacitance and the resultant rising pressure is compared with an adjustable-level reference pressure signal which defines the timing period. When the capacitance pressure exceeds the reference signal value, a comparison signal initiates the release of an obturator. The reference pressure propagates to the outlet of the device and produces the time-delay signal.

摘要： A function generator is provided which establishes an output signal according to a functional relationship determined by the preformed contour of an easily precut cam member. The function generator includes a variable gain controller section coupled to a proximity sensing motion balance servomechanism which varies the gain of the controller according to the sensed proximity of the servomechanism to the edge of the cam member without physical contact therewith. The cam member's position is in turn determined by an input signal which may be related to the controller input signals or may be an independent signal from a remote source. The gain and consequently the output of the controller is varied according to the functional relationship determined by the precut contour of the cam member.

摘要： An air conditioning system, especially for aircraft cabins, has a temperature control loop incorporating a signal processing control stage, in the form of a pulse logic network, to derive, from the difference or error signal received from a comparator, a control output signal suitable for driving a regulating motor to change the air flow conditions in a fresh air duct supplying the cabin. The cabin temperature is advantageously sensed by a resonant tube acoustic device delivering a pneumatic pressure oscillating output which is compared with a reference pulse frequency in fluidic logic of the comparator to derive a pulse frequency representing the difference or error. The control stage in turn derives from the error pulse frequency the regulator driving output, which is advantageously a polyphase output driving a stepping motor.
