TL;DR: In this article, a respiratory gas delivery system is presented to cyclically deliver a controlled volume of air to a patient by using a variable speed rotary compressor and a rotary electric motor.
Abstract: This invention is a respiratory gas delivery system to cyclically deliver a controlled volume of air to a patient. The system includes a variable speed rotary compressor (10) driven by a rotary electric motor (12) and a directional valve means (16), all of which are controlled by a microcomputer (26). The microcomputer includes means to select a reference value for the delivered air volume (44), means to measure the instantaneous flow rate (40), means to integrate the flow rate measurement during a delivery interval and means to adjust the compressor speed on the next succeeding delivery interval following a delivery interval in which the flow rate measurement is integrated.

TL;DR: In this article, a closed loop circuit involving a heat pump compressor for circulating fluid to heat and cool air within a building or the like is described. But it does not specify the type of closed loop.
Abstract: An energy conversion system, particularly for use in heating, cooling, and generating electrical and mechanical power for an area such as a dwelling. In one embodiment, vapor is alternately directed into one of two reservoir tanks so that working fluid in that tank is forced out of that tank by the vapor pressure and through a hydraulic motor, which powers a compressor and/or other devices such as an electrical power generator, garbage disposal, etc., before it returns to refill the other tank. The system includes a closed loop circuit involving a heat pump compressor for circulating fluid to heat and cool air within a building or the like. When the loop is set in a cooling configuration, compressed fluid passes through a first heat exchanger rejecting heat, and then through an expansion valve to a second heat exchanger, cooling the air about that exchanger before returning to the compressor. When the loop is set in a heating configuration, the compressed fluid in its gaseous state passes first through the second heat exchanger, where it transmits heat to the surrounding air, through the expansion valve and then through the first exchanger, where it receives heat not converted into shaft work by the hydraulic motor before returning to the compressor.
