Former name of capacitor, qv.
Also Keely's "condenser".
"The positive vibrations are the radiating or propulsive, the negative vibrations are the ones that are attracted towards the neutral center. The action of the magnetic flow is dual in its evolutions, both attractive and propulsive. The sound vibrations of themselves have no power whatever to induce dissociation, even in its lowest form. Certain differential, dual, triple and quadruple chords give introductory impulses which excite an action on molecular masses, liquid and gaseous, that increase their range of molecular motion and put them in that receptive state for sympathetic vibratory interchange which favors molecular disintegration, then, as I have shown, the diatonic enharmonic is brought into play, which further increases the molecular range of motion beyond fifty percent of their diameters, when molecular separation takes place, giving the tenuous substance that is necessary to induce progressive subdivision. This molecular gaseous substance, during its evolution, assumes a condition of high rotation in the sphere or tube in which it has been generated, and becomes itself the medium, with the proper exciters, for further progressive dissociation. The exciters include an illuminated revolving prism, condenser, and colored lenses, with a capped glass tube strong enough to carry a pressure of at least one thousand pounds per square inch. To one of these caps a sectional wire of platinum and silver is attached; the other cap is attached to the tube so screwed to the chamber as to allow it to lead to the neutral center of said chamber."
