Abstract: Embodiments of the present invention are directed toward systems and methods of transferring fluid using devices that have a rotatable housing (10) . One embodiment of the invention attaches a fluid-drive element (370,350) to a rotatable housing (10) to drive fluid into a conduit (390,381) for transfer. In another embodiment, a pitot tube (310) is attached to the rotatable housing (10) , the motion of the housing (10) driving fluid into the conduit for transfer. Other embodiments of the invention may utilize a pressure difference to drive fluid through a conduit (360,365) . Embodiments of the invention may also utilize baffles (340) to alter circulation of fluid that may be induced by the motion of the rotating housing (10) , to promote fluid transfer through a conduit. Some of the aforementioned embodiments may be especially useful in transporting fluid in a liquid ring pump with a rotatable housing.

Abstract: Various types and configurations of pump pods, heat-exchanger systems, and thermal/conductivity sensors are described above. Pump pods can be used in a wide variety of applications including but not limited to heat-exchanger systems and for pumping of bodily fluids or medical fluids. Thermal/conductivity sensors can be used in a wide variety of applications including but not limited to thermal/conductivity measurements of fluids and thermal/conductivity measurements in the context of heat-exchanger systems. Heat-exchanger systems may be used in a wide variety of applications to heat or cool fluids and are not limited to use with pump pods and thermal/conductivity sensors.

Abstract: A reciprocating positive displacement pumping system has a rigid chamber wall to which a flexible membrane is attached defining a pumping chamber. An inlet and outlet allow liquid flow. A rigid limit structure limits the movement of the membrane and the maximum volume of the pumping chamber defining an actuation chamber. An actuation port through which a fluid under positive or negative pressure can communicate with the actuation chamber is configured to connect to a positive pressure fluid reservoir and a negative pressure fluid reservoir through a valving mechanism for controlling the flow of control fluid between the actuation chamber and each of the reservoirs. An actuation chamber pressure transducer measures the pressure of the actuation chamber and a controller integrates pressure information from the actuation chamber pressure transducer over time during a stroke to detect an aberrant liquid flow condition.

Abstract: Embodiments of the invention are directed toward a novel pressurized vapor cycle for distilling liquids. In some embodiments of the invention, a liquid purification system is revealed, including the elements of an input for receiving untreated liquid, a vaporizer coupled to the input for transforming the liquid to vapor, a head chamber for collecting the vapor, a vapor pump with an internal drive shaft and an eccentric rotor with a rotatable housing for compressing vapor, and a condenser in communication with the vapor pump for transforming the compressed vapor into a distilled product. Other embodiments of the invention are directed toward heat management, and other process enhancements for making the system especially efficient.
