Abstract: A system for cancelling or attenuating noise in at least two positive displacement compressors proximately located from each other for use with a heating or cooling system. A lead compressor and a lag compressor have a controllable rotational speed and phase of operation. A controller selectably controls the rotational speed and the phase of operation of each of the compressors. The controller controls the rotational speed of the compressors at substantially the same speed for each compressor, with a phase-lock loop and a comparator circuit for each compressor. The controller controls the phase of operation of the compressors through an oscillator so that the lead and lag compressor pressure pulses are spaced between successive outlet pressure pulses to effectively double the combined pulsation frequency for noise attenuation.

Abstract: A method of determining a leakage in a piston machine comprising at least two pistons is provided. The rotational velocity of the piston machine, and therefore the volume flow through the piston machine, is varied periodically as part of a time-limited active test while measuring the differential pressure and the angular position. An angular position-based Fourier analysis of the measured values from differential pressure and rotational velocity measurements performed during the test are used to experimentally determine the amplitude ratio and phase angle difference between volume flow variations and pressure variations. The amplitude ratio and phase angle difference are used, together with an angular position-based Fourier analysis of the measurements of differential pressure and rotational speed made after the active test, to determine the amplitude and phase of the leakage flow.

Abstract: A pump system includes a fixed or variable capacity pump and a speed-related control mechanism to alter the capacity of a variable capacity pump or to alter the relief pressure of a fixed capacity pump in response to changes in the operating speed of the pump. A pressure generator comprising a volume of working fluid is rotated at a speed related to the operating speed of the pump and creates a forced vortex in the working fluid. The pressure induced in the working fluid of the forced vortex is used as a speed related control to alter the discharge pressure of the pump as desired.

Abstract: A cigarette making apparatus includes a cooling-water passage which allows a coolant to circulate along a flavoring-material supply path which connects an application nozzle for applying a flavoring material to a wrapping-paper web and a pump for supplying the flavoring material to the application nozzle, to thereby cool the flavoring material. A cooling unit controls the temperature of the coolant supplied to the cooling-water passage. Specifically, the cooling unit controls the temperature of the flavoring material by selectively activating a first control system for detecting the temperature of the coolant supplied to the cooling-water passage and controlling the temperature of the coolant, and a second control system for detecting the temperature of the flavoring material supplied to the application nozzle and controlling the temperature of the coolant. Since the temperature of the flavoring material is controlled to fix the viscosity thereof, the amount per unit area of the flavoring material applied to the wrapping-paper web is fixed only by controlling the drive of the pump depending on the rate of supply of the wrapping-paper web.
