Abstract: 1529766 Automatic control of gas compressors VILTER Mfg CORP 5 April 1977 [10 May 1976 28 Jan 1977] 14456/77 Heading G3N In a system comprising a rotary screw compressor 10 the capacity of which can be varied by means of a slide valve 20 and which is driven by an electric motor 11, a first means 82 measures a system parameter, e.g. pressure at compressor inlet 14, a second means such as C.T.100 measures an operating condition of the motor 11 which is related to compressor capacity, and signals from these two sources are fed to a comparator (proportioning relay) 60 which provides an output to adjust the position of the valve, and thus the compressor capacity, so as to keep the system parameter within a predetermined range. As described the compressed fluid is a refrigerant and the parameter may be inlet or outlet temperature or pressure, or temperature in the evaporator or of a coolant associated with the compressor. The relay 60 provides no output when its input signals are balanced but otherwise energizes one of two lines 67, 68 to open a corresponding one of solenoid valves 41, 42. Hydraulic fluid is then allowed to flow to or from a chamber 27 on the right hand side of a piston 26 fixed to the slide valve 20. Return force on the slide valve is provided by a spring 15.

Abstract: A nonlinear signal transducer U, such as a light-emitting diode or a semiconductive laser, is maintained at a suitable operating point by a constant biasing current and receives an electrical input signal by way of a series resistor R from a main amplifier AM of variable gain. The output voltage of the main amplifier is detected and integrated to provide a first reference voltage which is compared with the load voltage of the transducer U in a differential amplifier AE1, forming part of a first feedback loop, to adjust a voltage generator GT controlling the output voltage of the main amplifier AM so as to eliminate any voltage drop across the series resistor R as long as the input signal is absent or has an instantaneous magnitude equal to its mean value. A second feedback loop includes a peak-to-peak detector DP which emits a voltage proportional to the signal amplitude, that voltage being compared with a second reference voltage in a differential amplifier AE2 serving to adjust a current generator GC1 which controls the gain of the main amplifier AM. The second reference voltage may be varied manually or in response to changes in the output of the transducer U.

Abstract: A self-discharging centrifugal drum for clarifying and separating suspensions has an axially displaceable piston valve that is bounded above by a solids space and that opens and closes expulsion openings in the drum jacket. A closure compartment that can be charged with closure fluid is disposed below the piston valve and into which the closure fluid is supplied through a channel that is connected to an intermediate compartment for closure fluid. The closure compartment is evacuated to initiate discharge of the drum packing by a centrifugal valve. The valve that evacuates the closure compartment is a centrifugal valve that contains a movable valve cone, with the valve cone activated by control fluid and having a valve projection that is smaller in diameter than the valve cone and that is sealed into the drum jacket behind the valve cone so that the valve projection will extensively choke or close the channel that connects the closure compartment to the intermediate compartment when the valve cone opens. This insures not only sudden evacuation but also just as sudden charging of the closure compartment with closure fluid.

Abstract: A femtoammeter is disclosed which resists noise induced reversed bias of the ammeter amplifier and avoids long time constant recovery with unusually high measurement accuracy. The amplifier ammeter has a feedback loop which is provided with paired opposingly faced log diodes in parallel across the feedback circuit. Transients of negative or positive bias are accommodated without biasing the amplifier to a reverse polarity and having unacceptably long time constant recovery. Conventional temperature compensation, not possible with the parallel reversed diode configuration, is supplied by heat sinking the ammeter components, providing a log diode temperature sensor for the heat sinked components and controlling the heat sink operating temperature with a thermoelectric cooler. The temperature sensing log diodes output to a computer lookup table. The same temperature sensing log diode outputs to a bridge circuit operating the thermoelectric cooler. The thermoelectric cooler is polarized to heat or cool the heat sink to thermally adjust the ammeter to an optimum operating temperature. Automated bootstrap calibration is disclosed with reed switching for prevention of stray currents. Accuracy includes heretofore unattainable results.
