Abstract: A motion enhancing mechanism assembly suited for use with fluid control devices such as a piezoelectric modulating actuator of a proportional control valve. Range-limited axial motion of the actuator is transmitted through an amplifier disc to cause tilting of a control plate initially in sealing registration with an orifice ridge surrounding a fluid conduit aperture. Tilting of the control plate opens a wedge-like gap through which fluid may flow with larger conductance than is available with a planar gap of uniform height otherwise achievable with the range-limited motion of the actuator.

Abstract: A hydraulic system primary fluid reservoir in fluid communication with an auxiliary reservoir having a cartridge and an elastic fluid impervious chamber and apparatus for sealing the elastic fluid impervious chamber with the interior thereof in fluid communication with the inside air of an associated primary fluid reservoir. Said cartridge contains an oxygen absorber that removes oxygen molecules from the reservoir air. The cartridge includes a desiccant to dry the reservoir air. A metallic heat conduction rod is partially exposed to internal air and partly exposed to ambient air. The conduction rod is in close proximity to the oxygen absorber and desiccant in the cartridge. A cool portion on the conduction rod attracts hot humid internal air causing condensation of water near the surface of the conduction rod.

Abstract: A fire engine hose connector system and a method for using the system are reported. The system allows for rapid connection between the fire hose and the fire engine, and more importantly the system enables even more rapid disconnection. The fire engine and firefighting personnel may make a rapid escape form an overtaking wildfire. The ability to rapidly disconnect and escape from the fire scene allows the fire engine and personnel to access hydrant supplies that would otherwise not be available due to safety procedures that preclude connection when the long disconnect time requirements of prior art connectors place the escape of the fire engine and personnel at risk in a rapidly moving fire. The connector further includes a means to bend the connector for stress relief and ease of handling and multiple safety interlocks.

Abstract: Positive displacement using a connector with dual diaphragms is provided. For example, the connector includes a single fluid flow path, an air chamber and a valve. The single fluid flow path is configured for delivering fluid to a person and configured for receiving fluid from a person.

The valve plug comprises two diaphragms that separate the air chamber from the single fluid flow path. The valve plug is configured for creating positive displacement by returning the valve plug to its uncompressed state when the actuator is removed from the connector.

Abstract: Flow control devices and methods using the flow control devices are provided. In a general embodiment, a cassette includes a housing having a constrictor, a tube attached to the housing and positioned through the constrictor, and a ball positioned inside the tube.

As a result, the cassette is designed to prevent free flow of fluid when an enteral feeding tube set is not installed in a pumping device.
