Abstract: A valve jacket is provided to surround a valve and contain any liquid that may leak from the valve as a part of a secondary containment system of the type found a gasoline service stations. The valve jacket is provided as a hollow body with a pair of openings through which a pair of primary pipelines associated with the valve can extend. One of the two openings is sized large enough that the jacket can be slid over the valve. The two openings are sealed to a pair of secondary conduits associated with the primary pipelines. A reservoir can be provided in the jacket to collect any liquid and a sensor can be provided in the reservoir to detect the presence of liquid in the reservoir. Preferably, a removable and sealable cap is provided to allow access to the valve for operation.
Abstract: A catalyst dumping device (10) for unloading a catalyst (50) inside a reactor (1), in which smashed used catalyst is thrown into a dumping pipe (11) formed of a plurality of pipe member (12) provided to the reactor (1) to unload to outside of the reactor (1) by fall by dead weight. Accordingly, the catalyst can be unloaded only by throwing the catalyst into the dumping pipe (11), thereby improving work efficiency. Furthermore, no special apparatus such as a vacuum apparatus is unnecessary, thereby reducing cost for the special apparatus.
Abstract: A quick connector fitting assembly is provided which includes a fitting which releasably connects to a well casing for providing an interface for the attachment of various types of well related equipment. The quick connector fitting connects using fasteners to a lip or groove formed on the casing. The fasteners can easily connect or disconnect from the groove or lip facilitating the quick connection and disconnection of the fitting from the casing.
Abstract: A quick connect/disconnect coaxial hose assembly comprises male and female half hose assemblies wherein the half hose assemblies respectively comprise a male and female connector, an outer tube member for conducting a first fluid therethrough, an inner tube member for conducting a second fluid therethrough, a joint retainer nut member for securing the male and female connectors together, and a sleeve member mechanically and fluidically connecting axially inner ends of the inner tube members together. Threaded disengagement of the joint retainer nut member releases the male and female connectors from each other, whereby the half hose assemblies may be readily pulled apart in opposite axial directions disengaging the axially inner end of one of the inner tube members from the sleeve member so as to achieve quick disconnection of the hose assembly.
