ABSTRACT:
A gas purifier comprising a casing, and two magnetically sensitive reeds arranged in the casing so that one reed extends from one end wall of the casing and the other reed extends from the other end wall of the casing and the free ends of the reeds overlap one above another with a small gap therebetween to form opposing contacts. The magnetically sensitive reeds are magnetically moved by a driving coil so that the contacts are opened and closed like a switch. This operation of the contacts and the contact load coil induces a glow discharge by which a gas is purified by an action of the plasma. A catalyst is carried by the contacts or the casing. Therefore, gas is purified synergically by the action of the plasma and the action of the catalyst. It is also possible to operate the magnetically sensitive reeds, or the like electrodes, by an AC voltage to induce a glow discharge.
