A surgical instrument for use in connection with a pneumatically powered tool having a firing mechanism operably supported therein that is movable between an unactuated position and an actuated position. In various embodiments, a drive system is supported by at least one of a handle assembly and an elongate shaft assembly and is configured to selectively apply a firing motion to the firing mechanism of the pneumatically powered tool to cause the firing mechanism to move from the unactuated position to the actuated position in response to a flow of gas from a source of gas fluidically coupled to the drive system. A travel monitoring member is operably supported by the handle assembly and is linked to the drive system to provide an indication of progress of the firing mechanism of the pneumatically powered tool as the firing mechanism moves from the unactuated position to the actuated position.
摘要:
The invention relates to a valve (1) that comprises a valve needle (2), a valve housing (3) and a valve face (4) for introducing a medium into a container (5). When the valve is closed, the front face (7) of the valve needle (2) and the valve housing (3) are substantial flush with an inner surface (8) of the container. (5). Low tolerance range fits are provided between the container (5) and the valve housing (3) and/or between the valve housing (3) and the valve needle (2). The present invention is especially suitable for cooling and freezing liquid, pasty or lumpy products, especially food products or pharmaceutical products.
摘要:
A regulator provided with an inlet connection (8) for connection to a gas source (1), such as for instance a gas cylinder, a compressor or a gas generator, and provided with an outlet connection (9) for connection to a further gas pipe system (4), the regulator (2) being provided with a high pressure chamber and a low pressure chamber which are mutually connected by a pressure reductor, such that in use the gas pressure in the low pressure chamber is lower than the pressure in the high pressure chamber, the regulator (2) being provided with a connection (16) for an exchangeable indicator unit (17), the connection (16) being such that the gas coming from the gas source (1) flows through the indicator unit (17), the indicator unit (17) being provided with means for signaling undesirable components in the gas flowing through the indicator unit (17).

摘要:
A carbon dioxide dry cleaning system features a pair of liquid carbon dioxide storage tanks (18,20) in communication with a compressor (14). A sealed cleaning chamber (32) contains the objects to be cleaned. By selectively pressurizing the storage tanks with the compressor, liquid carbon dioxide is made to flow to the cleaning chamber (32) through cleaning nozzles (53) so as to provide agitation of the objects being dry cleaned. Liquid carbon dioxide displaced from the cleaning chamber returns to the storage tanks. In an alternative embodiment, a single storage tank is pressurized via a compressor with gas from the cleaning chamber so that liquid solvent from the storage tank travels to the cleaning chamber through nozzles. The objects in the cleaning chamber are agitated by a rotating basket. After a prewash cycle, liquid solvent from the cleaning chamber is directed to a still, The liquid solvent in the still is boiled through a connection with the head space of the cleaning chamber. The still may be positioned within the storage tank and partially surrounded with a shroud for efficient heating of the still with gas from the cleaning chamber. During agitation, liquid solvent from the cleaning chamber may be heated and filtered.
摘要:
An assembly comprising an intermediate volume of medium-pressure gas (8) in a transportable housing (3) which is advantageously combined with a user apparatus (4) and selectively connectable to a high-pressure gas supply (1) by coupling it to a filling unit (2) via a quick connection system (15, 16). The assembly is particularly useful in portable welding apparatuses.
