CONDENSER, one who or that which 'condenses.
Steant-engine.—An apparatus for re ducing to a liquid form the steam in front of the piston, so as to obtain a partial vacuum at that point, and thus utilize the natural pressure of the atmosphere. Watt invented the injection condenser and the separate condenser. The surface con denser has a series of flat chambers or tubes, usually the latter, in which the steam is cooled by a body of water sur rounding the tubes. Distilled water for ships' use is obtained by the condensa tion of steam in a surface condenser.
Distilling.—The still-condenser is an apparatus generally made of the worm tub form: the coil containing the alco holic vapor traversing a tub which re ceives a constant accession of cold water, condensing the vapor in the coil. The liquid escapes at a cock valve below.
Metal.—An apartment in which metal lic or deleterious gaseous fumes are con densed to prevent their escape into, and contamination of, the atmosphere. The
device consists of a prolonged duct for the fumes, with showers of water to con dense the volatile matters.
Electricity.—(1) An instrument for concentrating electricity by the effect of induction. It usually consists of a con folded sheet of tin-foil, whose layers are separated by a thin sheet having a non conducting surface.
(2) With induction apparatus, a de vice for absorption or suppression of the extra current, induced by the rapid breaks in the main current.
(3) An instrument in which an elec tric spark passes between the poles in a closed glass cylinder, so as to be employed in burning metals in an atmosphere of any given tenuity or specific chemical character, to obtain the spectra of metals or gases free from accidental character istics of the general atmosphere for the time being.
