Generator
an apparatus for generating carbonic acid gas for charging soda-fountains, or bottles with aërated water. In chemistry, a term used to denote the elements or compounds from which a more complex substance is obtained. Thus ethyl, alcohol, and acetic acid are the generators of acetic ether; and benzoic acid and glycocoll are the generators of hippuric acid. By the action of acids or alkalies these substances can be resolved into their generators , and, so the constitution of a con complex body can be determined; thus, Lecithin, a constituent of the brain, has the formula C4H0NR: 09; it has six generators, glycerin, phosphoric acid, stearic acid, glycol, methyl alcohol, and ammonia; therefore it is found to be a distearate glycerophosphate of choline, and choline has been found to be a trimethyl oxyethyl ammonium hydrate (CH3)3N CH OH CH OH. In distilling, a retort in which volatile hydrocarbons are distilled from liquid or solid matters.
In electricity, a DYNAMO-ELECTRIC MA- CHINE (q. v.) In music, a ground note, fundamental bass, root, derivative. The principal sound or sounds by which others are produced, as the lower C for the treble of the harpsichord, which be- GENESEE side its octave will strike an attentive ear with its twelfth above or G in alt, and with its fifteenth above or C in alt. In steam, a vessel in which steam is generated from water, for use in a steam engine, a heating apparatus, etc. The term was first applied to the Perkins steam boiler, in which water in small quantity was heated to a high temperature . It is now specifically applied to a class of instantaneous generators. The name is now rapidly coming into use for all apparatus for generating steam , being held to be more correct than the usual term.
