Pressure core sampler: A tool designed to retrieve a sediment core sample while retaining the pressure at depth. [5] Pull past Martin-Decker: Exert extreme tension on stuck pipe, so much so that the pointer needle revolves off-scale beyond the logo of a popular manufacturer of weight indicators, Martin-Decker.

Gatling gun: A hand-crank operated cannon named after its inventor, Richard Gatling. In modern usage, a Gatling often refers to a rotary machine gun. Gauge: The gauge of a firearm is a unit of measurement used to express the diameter of the barrel. The M60, a general purpose machine gun
In other words, the pressure on either end of the liquid (shown in blue in the figure) must be balanced (since the liquid is static), and so P a = P 0 + hgρ. In most liquid-column measurements, the result of the measurement is the height h, expressed typically in mm, cm, or inches. The h is also known as the pressure head. When expressed as a ...
CITHP – closed-in tubing head pressure (tubing head pressure when the well is shut in) CIV – chemical injection valve CK – choke (a restriction in a flowline or a system, usually referring to a production choke during a test or the choke in the well control system)
a cylindrical ring of steel whose inside diameter is finished to gauge tolerance and is used for checking the external diameter of a cylindrical object. Strain gauge: a device used to measure the strain of an object. Thread pitch gauge, also called a threading gauge, pitch gauge, or screw gauge a device used to measure the pitch or lead of ...
Gauge blocks (also known as gage blocks, Johansson gauges, slip gauges, or Jo blocks) are a system for producing precision lengths. The individual gauge block is a metal or ceramic block that has been precision ground and lapped to a specific thickness. Gauge blocks come in sets of blocks with a range of standard lengths.
An air-pressurized-water fire extinguisher is similar but its water is expelled by the air pressure, it is held by one person, and a flexible hose makes aiming the water stream easy. Handtub A historical fire engine pumped by hand with the water supply held in a tub or cistern on the wagon, the water supply delivered by a bucket brigade.
Diagram of a fireplace hand-bellows. A bellows or pair of bellows is a device constructed to furnish a strong blast of air.The simplest type consists of a flexible bag comprising a pair of rigid boards with handles joined by flexible leather sides enclosing an approximately airtight cavity which can be expanded and contracted by operating the handles, and fitted with a valve allowing air to ...
