Disclosed herein are robust disposable alternating tangential flow (ATF) housing and diaphragm pump units and associated methods of manufacturing, testing, wetting, and using the same.

A method of compressing gas includes maintaining a volume of gas at a first pressure within a first chamber. Pressurized liquid is forced into the first chamber through a nozzle having a curved profile. Based on the Coanda effect, the liquid compresses the volume of gas to a second pressure greater than the first pressure. The liquid is separated from the gas in a second chamber while maintaining the gas at the second pressure to provide compressed, dry gas.

A device for locking a rod member is provided. The device includes a body section having a vertical hole therein, and a ring-type locking unit and a piston serially arranged along the hole, wherein the rod member is disposed in the hole to be axially movable through the locking unit and the piston. The locking unit may be a lock block including an outer ring having an inclined surface on one side thereof, thereby defining a wedge-type space, an inner ring coaxially disposed in one side of the outer ring and accommodating a pressurizing member interacting with the inclined surface, and a spring disposed in the other side of the outer ring so as to elastically connect the outer ring and the inner ring.

A variable-power magnetohydrodynamic accelerator, mixer, and compressor for fluids, consisting of several parts, including 1) an array of spiraled adjustable-power accelerators (SAPAs), with integrated electrostatic-pre-charging components (EPCCs) and electromagnetic accelerator components (EACs); and 2) a multi-shell core with cooling system.

The present disclosure discloses a flamed-based vacuum generator, including a shell and a combustion assembly, where the shell has a cavity, the cavity being a space having at least one opening, and the combustion assembly includes a combustible object and an igniter, the igniter being configured to ignite the combustible object, the combustible object generating a flame in the cavity, and the flame extinguishing in the cavity. In the present disclosure, through in-depth study of the internal mechanism of vacuum generated by flame combustion, it is found that the extinguishing process of a flame is the key to the generation of vacuum, and a larger flame and more sufficient combustion indicate a higher vacuum pressure generated in the cavity after the flame is extinguished.

A valve assembly for an inflation system that includes a pressure relief valve and a vent valve. The pressure relief valve has a pressure relief housing and a pressure relief valve poppet. The pressure relief housing defines a first pressure relief cavity that is disposed between a first end wall defining a first flow port and a first wall defining a passageway and a second pressure relief cavity disposed between the first wall and a second wall. The pressure relief valve poppet is movably disposed within the first pressure relief cavity and the second pressure relief cavity. The vent valve has a vent housing and a vent valve poppet. The vent housing defines a vent cavity that is disposed between the second wall defining a vent flow port and a second end wall. The vent valve poppet is movably disposed within the vent cavity.
