Striking "bells" a little before the proper time at the end of a watch. More generally, doing something unjustifiably or unnecessarily early.

The passing of a substance or force into the body of another substance.

A temperature scale based on absolute zero. Same as Kelvin temperature scale.

A unit fitted with control levers, buttons, etc., as appropriate.

The process in which incident radiation is retained by a substance. A further process always results from absorption.

Current efficiency of the anode..

A type of air cooling device that uses absorption cooling to cool interior spaces.

A line leading from forward on the ship and secured to a forward inboard thwart of the boat in such a way as to permit quick release.

A system in which a secondary fluid absorbs the refrigerant, releasing heat, then releases the refrigerant and reabsorbs the heat. Ammonia or water is used as the vapor in commercial absorption cycle systems, and water or lithium bromide is the absorber.

The power (in Watts) used by a device to produce useful work. Also called input power.

An instrument whose calibration can be determined by means of simple physical measurements on the instrument. Compare to secondary instrument.

The efficiency of the filter in removing some portion of a specified test contaminant under a specific set of laboratory conditions. It determines the mass of the contaminant the filter removes from a known sample introduced to the filter.
