Definitions for "Compensator"
Keywords:  recoil, muzzle, brake, firearm, gases
A kind of muzzle brake which diverts powder gases upward to reduce the upward recoil.
A muzzle attachment that compensates for an undesirable handling characteristic of a discharged firearm. Usually refers to the Recoil Compensator.
A device attached to the muzzle end of the barrel that utilizes propelling gases to reduce recoil. Also, see Muzzle Brake.
a piece of mineral with known properties that "compensates" for some deficiency in the optical train
A device with known, fixed or variable retardation, and vibration direction, used for determining the amount of retardation (hence, the thickness and birefringence) of an anisotropic substance. It is also used to determine the sign of elongation of elongated anisotropic specimens. The most common compensator is the first-order red (530-550 nm retardation), but other compensators frequently used include the quartz wedge (1-6 orders), the Berek (1-3, 1-5, 1-30 orders), the quarter-wave (~137 - 147 nm), and the Sénarmont. Compensators are typically introduced into the light path through a bodytube slot between the objective and the eyepiece.
A birefringent slab of optical quartz, mica, or similar material that is positioned almost anywhere between the polarizer and analyzer in a polarized microscope, but limited to the exterior of the prisms and other imaging components of a DIC microscope. The slab can be tilted and/or rotated to achieve varying optical effects. A compensator changes the optical path difference between orthogonal wavefronts, and can be utilized to perform quantitative measurements of the relative ordinary and extraordinary wavefront retardations, or for qualitative purposes in adjusting image contrast and brightness. Compensator plates are often used in DIC microscopy for optical staining of transparent specimens.
An expansion joint designed to take up thermal expansion. ( 099)
When used within the context of this web site, compensator refers to an expansion compensator ( Series 8500) which is a specialized type of expansion joint. Compensator is sometimes used when referring to expansion joints in European countries.
This controls the heat to the wire-temperature range. The key control on an L-Sealer, it is a spring-mounted screw adjustment located on the extreme left end of the front seal bar which controls the heat of the seal wires by controlling the flow of electricity to these wires. When the seal cycle is initiated, electricity flows into the wires and they heat up and expand as the springs keep the wires taut. As the compensator contracts the screw due to the expansion of the heated wire, the electrical flow is terminated and the wire begins to cool and contract. (All Segment 1 machines incorporate a compensator except for the 6020 series, which incorporates an Electronic Heat Simulator which uses a capacitor to monitor heat in the seal wires.)
One who, or that which, compensates; -- a name applied to various mechanical devices.
a device in the beam path which can insert an adjustable phase shift (a delay, in effect)
a device that acts as a channel inverse, and thereby can be used to reduce signal distortions
Keeps drill-sting stationary while semi-submersible and derrick move.
a gravity based pendulum mechanism
a nontransactional object that is used by the system to represent a transactional component at the end of the transaction

An iron plate or magnet placed near the compass on iron vessels to neutralize the effect of the ship's attraction on the needle.
An electrical matching network to compensate for electrical impedance differences.
