An o-ring boss seal is a technique for joining two fluid-carrying pipes, hoses, or tubing. In an o-ring boss (abbreviated ORB) system, a male-threaded part is inserted into a female-threaded part, providing a mechanical seal. This system differs from others in that a nut is tightened over an o-ring in a chamfered area, creating a fluid-tight ...
Digital Addressable Lighting Interface (DALI) is a trademark for network-based products that control lighting. The underlying technology was established by a consortium of lighting equipment manufacturers as a successor for 1-10 V/ 0–10 V lighting control systems, and as an open standard alternative to several proprietary protocols.
Marman clamps are used extensively in spaceflight systems and are common mechanical load-transfer and clamping mechanisms for connecting the upper stage and the satellite payload of space vehicles, [3] [4] for example, on the Cassini Plasma Spectrometer on the Cassini orbiter. They may also be used to join stages of a booster rocket. [3]
Typical O-ring and application. An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface.
Lumber, tools, hardware, garden supplies & plants Handy Andy Home Improvement Centers was founded as Arrow Lumber Company by Joseph Rashkow in 1947 on the south side of Chicago. His son, Ronald Rashkow, bought out the single store operation in 1967 from his father.
Others have suggested that the term gandy dancer was coined to describe the movements of the workers themselves, i.e., the constant "dancing" motion of the track workers as they lunged against their tools in unison to nudge the rails, often timed by a chant; as they carried rails; or, speculatively, as they waddled like ganders while running on ...

this pumping system is suitable only if the head is relatively low. If one wants to obtain a high head, one has to choose a conventional pumping system. because of the principle, air (oxygen) dissolves in the liquid. In certain cases, this can be problematic, as, for example, in a waste water treatment plant, before an anaerobic basin.
