An instrument which measures the effective terrestrial radiation. See Angstrom pyrgeometer.

A type of heating system where heat, resulting when electric current flows through an "element" or conductor, such as Nichrome, which has a high resistance, is radiated to a room.

A device that tracks the movement of the sun; used to orient solar concentrating systems.

A refraction phenomenon similar to a parahelion, but occurring generally at a distance of 120

Front of a container or trailer - opposite the tail.

To break loose from a mooring, anchor or docking.

A coating process, similar to gas carburizing and carbonitriding, whereby a reactant atmosphere gas is fed into a processing chamber where it decomposes at the surface of the workpiece, liberating one material for either absorption by, or accumulation on ...

An instrument used for measuring geometric angles. See radio direction-finder.

A thermal storage wall is a south-facing wall that is glazed on the outside. Solar heat strikes the glazing and is absorbed into the wall, which conducts the heat into the room over time. The walls are at least 8 in thick. Generally, the thicker the wall, ...

A process of removing soil, scale, or corrosion products from a metal surface by subjecting it as an electrode to an electric current in an electrolytic bath.

The upper surface of a column of liquid.

The positive direction of electrode potential, thus resembling noble metals such as gold and platinum.

Additional thickness of planking on a wooden ship about her waterline to give the vessel more stability.

A device that removes contaminants, by mechanical filtration, from the fresh air stream before the air enters the living space. Filters can be installed as part of a heating/cooling system through which air flows for the purpose of removing particulates b ...

Secure hatches and loose objects both within the hull and on deck.

The stage on a fixed river gauge at which it is necessary to begin issuing warnings or river forecasts if adequate precautionary measures are to be taken before flood stage is reached.

(1) A nautical instrument, on the arc of which is a finely graduated scale showing degrees and minutes, with adjustable reflectors, etc.; used to find the altitude of heavenly bodies, angular distances, etc. (2) On a steering gear, the rudder quadrant is ...
