GYRO ERROR

The error in the reading of the gyrocompass, expressed in degrees east or west to indicate the direction in which the axis of the compass is offset from true north.

HALVING

The process of adjusting magnetic compass correctors so as to remove half of the deviation on the opposite cardinal or adjacent intercardinal headings to those on which adjustment was originally made when all deviation was removed. This is done to equalize the error on opposite headings.

GYROCOMPASS

A compass having one or more gyroscopes as the directive element, and which is northseeking. Its operation depends upon four natural phenomena, namely gyroscopic inertia, gyroscopic precession, the earth's rotation, and gravity. When such a compass controls remote indicators, called GYRO REPEATERS, it is called a master gyrocompass.

END CAP

A ported or closed cover for the end of a filter element.

FILTER HEAD

An end closure for the filter case or bowl that contains one or more ports.

FILTER HEAD

An end closure for the filter case or bowl which contains one or more ports.

STEALER

A single wide plate that is butt-connected to two narrow plates, usually near the ends of a ship.

HEELING ERROR

The change in the deviation of a magnetic compass when a craft heels, due to the change i

TERMINAL VELOCITY

The highest sustained air stream velocity existing in the mixed air path at the end of the throw.

POLAR COMPOUND

A chemical compound whose molecules exhibit electrically positive characteristics at one extremity and negative characteristics at the other. Polar compounds are used as additives in many petroleum products. Polarity gives certain molecules a strong affinity for solid surfaces; as lubricant additives (oiliness agents), such molecules plate out to form a tenacious, friction- reducing film. Some polar molecules are oil-soluble at one end and water-soluble at the other end; in lubricants, they act as emulsifiers, helping to form stable oil-water emulsions. Such lubricants are said to have good metal-wetting properties. Polar compounds with a strong attraction for solid contaminants act as detergents in engine oils by keeping contaminants finely dispersed.
