摘要： A Micro-Electro Mechanical device includes a movable mechanical structure and a bias mechanism. A bubble confinement region is defined by at least a portion of the movable mechanical structure. A bubble generation mechanism produces a bubble within the bubble confinement region. The bubble displaces the movable structure and alters the configuration of the bias mechanism, thereby producing useful work.

摘要： A turbo-machine includes a housing (1); a rotor (3) of a centripetally flow-through expansion turbine stage (4) overhung on the one end of the rotor shaft; a rotor of a radially flow-through compressor stage (6) overhung on the other end of the rotor shaft; a measuring system (7) for directly detecting an axial thrust of the rotor shaft (2) supported in roller bearings (8); and at least two pressure control valves (10, 11), which are installed in control lines (12, 13) and controlled by a controller (9). Via the control lines (12, 13), a rotor piston surface (14), which is sealed against the housing (1) and located on the rear side of one of the rotors, for example the compressor rotor (5), can be acted upon by the pressure (p1) prevailing on the inlet into the compressor stage, and the pressure (p2) on the outlet of the compressor stage (6). The controller (9) actuates either the pressure control valve (10) in the control line (12) acted upon by the compressor inlet pressure (p1) or the pressure control valve (11) in the control line (13) under the compressor outlet pressure (p2) according to the measured axial thrust, in order to eliminate an axial thrust outside of a preselected nominal value range by raising or reducing the pressure on the rotor control surface (14).

摘要： Applicant provides a novel liquified booster pump. The pump takes high pressure boosted gas to a higher pressure. The pump is a pneumatically driven liquified gas booster pump with a shuttle valve enclosed within a body of the pump. Furthermore, the gas which is use to be boosted is carried from an inlet on the body of the pump to an outlet on the body of the pump, the boosted gas being carried entirely within the body of the pump with no external tubing. The pneumatically driven booster pump has a double ended piston within the central body and at least one shuttle valve incorporated in the piston for transferring gas from one side of the piston to the other.

摘要： A metering device contains a rotor which defines elongate chamber, there being a shuttle contained within the chamber movable between two terminal end positions. Frusto-conical surfaces defined on the rotor cooperate with annular members defining corresponding seats. One passage extends from one end of the chamber to one frusto-conical surface, and another passage extends from the other end of the chamber to the other frusto-conical surface. Each annual element defines a respective inlet and outlet for fluid and a shuttle is present within the chamber. As the rotor rotates, the shuttle effects a shuttling movement thus measuring dispensed volumes of fluid. A sensor is provided to detect physical contact of the shuttle with the end of the chamber to cause the rotor to advance.

摘要： Pump chambers are disclosed that include at least one spacer element therein to prevent any gas in the pump chamber from being pumped from the pump chamber during pumping. In some embodiments, the pump chambers are included in removable pumping cartridges that are constructed and configured for coupling with reusable pump drives. Some embodiments of pump chambers including spacer elements therein comprise a substantially rigid component forming a wall of the pump chamber with a flexible or movable membrane disposed on the wall to form the chamber. Spacer elements in such pump chambers are, in some embodiments, attached to a wall of the substantially rigid component so as to prevent the movable/flexible membrane from contacting the wall during pumping.
