Gear

A hand tool for assembling and disassembling a work piece. The hand tool can be configured for assembling and disassembling a work piece having a plurality of linkable units. The hand tool can include a first work station where at least one assembling operation can be performed and a second work station where at least one disassembling operation can be performed.

Hand tool for assembling and disassembling roller chain

A modular electro-mechanical agent having a plurality of modules including mechanical and electrical components, that can be constructed to complete at least one pre-determined task and/or contribute in performing the at least one pre-determined task. The electro-mechanical agent can include extension modules and can be altered as per user preference to add, eliminate or modify any features of the agent for completing and/or participating in a plurality of pre-determined tasks.

Modular electro-mechanical agent

A pump cassette comprising an outer flexible membrane covering flowpaths, valve chambers and pump chambers of the cassette is designed to be actuated by a control gasket on a base unit arranged to move designated valve and pump portions of the cassette membrane. The gasket valve control or actuation region is at least partially bounded by a vacuum channel facing the outside of the gasket so that a constant vacuum can be applied between the gasket valve control or actuation region and the adjacent portion of the cassette membrane. An improved version of the vacuum channel comprises a flexible inner wall of the vacuum channel flexes or partially collapses away from the cassette valve seat, while still maintaining patency of the vacuum channel during the application of negative pressure on the gasket valve actuation region to open the cassette valve.

Pressure control gaskets for operating pump cassette membranes

Wheel

A pump cassette comprising an outer flexible membrane covering flowpaths, valve chambers and pump chambers of the cassette is designed to be actuated by a control gasket on a base unit arranged to move designated valve and pump portions of the cassette membrane. The performance of a cassette valve may improved by optimizing the configuration of the valve control region of the control gasket overlying the cassette valve. This may improve both fluid flow through the valve and reduce the amount of vibratory noise associated with opening the valve. The gasket valve control or actuation region is at least partially bounded by a vacuum channel facing the outside of the gasket so that a constant vacuum can be applied between the gasket valve control or actuation region and the adjacent portion of the cassette membrane. An improved version of the vacuum channel comprises a flexible inner wall (contiguous with the valve control region) so that the inner wall flexes or partially collapses away from the cassette valve seat, while still maintaining patency of the vacuum channel during the application of negative pressure on the gasket valve actuation region to open the cassette valve.
