Resistance of an audio-frequency transducer when its moving elements are blocked so they cannot move; represents the resistance due only to electrical losses.

CARBON TRANSDUCER

A transducer consisting of carbon granules in contact with a fixed electrode and a movable electrode, so that motion of the movable electrode varies the resistance of the granules.

MEGOHMMETER

An instrument which is used for measuring the high resistance of electrical materials of the order of 20,000 megohms at 1000 volts; one direct-reading type employs a permanent magnet and a moving coil.

ENGINE BALANCE

Arrangement and construction of moving parts in reciprocating or rotating machines to reduce dynamic forces which may result in undesirable vibrations.

DISSIPATION LOSS

A measure of the power loss of a transducer in transmitting signals, expressed as the ratio of its input power to its output power.

GRAVITY BED

A moving body of solids in which particles (granules, pellets, beads, or briquets) flow downward by gravity through a vessel, while process fluid flows upward; the moving-bed technique is used in blast and shaft furnaces, petroleum catalytic cracking, pellet dryers, and coolers.

BOW SPRING LINE

A bow pivot line used in docking and undocking, or to prevent the boat from moving forward or astern while made fast to a pier.

UPDRAUGHT

A rapid vertically moving parcel of air found in thunderstorms.

LEVECHE

A warm wind in Spain, either a foehn or a hot southerly wind in advance of a low pressure area moving from the Sahara Desert.

FRICTION ERROR

The error of an instrument reading due to friction in the moving parts of the instrument

LEADING LINE

On a nautical chart, a straight line, drawn through leading marks. A ship moving along such line will clear certain dangers or remain in the best channel.
