A pipe plug is a tool or material for the temporary sealing of pipelines in sewerage and other liquid and gas transportation systems; typically for maintenance or non-pressurized line testing. A pipe plug is also known as an inflatable plug, [1] mechanical pipe plug, [2] pipe test plug, pipeline isolation plug, expandable plug, pipe bung, pipe ...
The final commercial evolution of the uniflow engine occurred in the United States during the late 1930s and 1940s by the Skinner Engine Company with the development of the Compound Unaflow Marine Steam Engine. [1] This engine operates in a steeple compound configuration and provides efficiencies approaching contemporary diesels.
A Schlenk line with four ports. The cold trap is on the right. Close-up view, showing the double-oblique stopcock, which allows vacuum (rear line) or inert gas (front line) to be selected. The Schlenk line (also vacuum gas manifold) is a commonly used chemistry apparatus developed by Wilhelm Schlenk. [1] It consists of a dual manifold with ...
The other end of the plug is often exposed to the outside of the valve too, but with a mechanism that retains the plug in the body. Handwheel operated plug valve. The simplest and most common general type of plug valve is a 2-port valve [1] [2] with two positions: open to allow flow, and shut (closed) to stop flow. Ports are openings in the ...

Soo Line 346 in 1961, showing the Kinkan-Ripken arm on the connecting rod at the right hand edge of the picture Kingan-Ripken valve gear. This is a Walschaerts-type gear in which the combination lever is linked to an arm on the connecting rod, near its small end, instead of to the crosshead.
The iOverlander [2] database maintained by travelers, My LPG [3] and the Facebook group "Cooking Gas Around the World [4]" provide more information about individual sources per country. Much general information about global LPG use and standardization is available from the World LPG Association [ 5 ] and the AEGPL [ 6 ]
A gas bubbler acts as a one-way valve—gases (hot air, evolved gases, solvent vapors) from the inlet will bubble through the fluid before being vented to the atmosphere. If there were an underpressure in the reaction vessel (such as when heat is removed, and the gases within contract), some fluid is sucked into a sump to equalize the pressure ...
