Industrial. In the extraction of petroleum (and other heavy-duty fluid handling contexts), a choke valve (or "choke") is an adjustable flow limiter that is designed to operate at a large pressure drop, at a large flow rate, for a long time. A choke is often a part of the "Christmas tree" at the wellhead . The most familiar choke design is a ...
Craftsman is a line of tools, lawn and garden equipment, and work wear. Originally a house brand established by Sears, the brand is now owned by Stanley Black & Decker . As with all Sears products, Craftsman tools were not manufactured by Sears during that company's ownership, but made under contract by various other companies.
Choker setter. A choker setter or choke setter is a logger who attaches cables to logs for retrieval by skidders or skylines. [1] [2] The work process involves the choker setter wrapping a special cable end (choker) around a log and then moving clear so the yarding engineer (e.g. skidder operator) can pull the log to a central area.

Barker lever. The Barker lever is a pneumatic system which multiplies the force of a finger on the key of a tracker pipe organ. It employs the wind pressure of the organ to inflate small bellows called "pneumatics" to overcome the resistance of the pallets ( valves) in the organ's wind-chest. This lever allowed for the development of larger ...
Automated manual transmissions can be semi-automatic or fully-automatic in operation. Several different systems to automate the clutch and/or shifting have been used over the years, but they will generally use one of the following methods of actuation for the clutch and/or shifting: hydraulic or electro-hydraulic actuation, [12] electro-mechanical, [13] pneumatic, [6] [14] [15] electromagnetic ...
Choke manifold. In oil and gas production a choke manifold is used to lower the pressure from the well head. It consist of a set of high pressure valves and at least two chokes. These chokes can be fixed or adjustable or a mix of both. The redundancy is needed so that if one choke has to be taken out of service, the flow can be directed through ...
