Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
98 words
An ionization device comprising: an ionization electrode exposed to the atmosphere; a source of high DC voltage; means for coupling said ionization electrode to said source of high DC voltage; an insulative housing member disposed in spaced non-touching adjacent relationship to said ionization electrode; a wire coupled to ground; and an insulative peripheral coating completely surrounding said wire; said thus coated wire being disposed between said insulative housing member and said electrode in an uninterrupted line of sight with respect to said ionization electrode and providing a controlled flow of electric charges from said insulative member to ground.
Claim 2
Dependent Claim
98 words
An ionization device comprising: an ionization electrode exposed to the atmosphere; a source of high DC voltage; means for coupling said ionization electrode to said source of high DC voltage; an insulative housing member disposed in spaced non-touching adjacent relationship to said ionization electrode; a wire coupled to ground; and an insulative peripheral coating completely surrounding said wire; said thus coated wire being disposed between said insulative housing member and said electrode in an uninterrupted line of sight with respect to said ionization electrode and providing a controlled flow of electric charges from said insulative member to ground.
Claim 3
Dependent Claim
28 words
An ionization device according to claim 1, wherein said insulative housing member and said associated coated wire are disposed in a generally surrounding arrangement about said ionization electrode.
Claim 4
Dependent Claim
29 words
An ionization device according to claim 1, wherein said insulative housing member comprises a generally cylindrical tubular shield member disposed substantially equidistant to the periphery of said ionization electrode.
Claim 5
Dependent Claim
59 words
Ionization apparatus according to claim 1 and comprising a plurality of said ionization electrodes; a plurality of said insulative housing members disposed at discrete locations remote from one another; and a plurality of said coated wires; and wherein said means for coupling comprises means for selectively coupling said source of high DC voltage to said plurality of ionization electrodes.
Claim 6
Dependent Claim
54 words
Ionization apparatus according to claim 1 and comprising a plurality of said ionization electrodes; and wherein: said means for coupling comprises means for coupling said source of high DC voltage to said plurality of ionization electrodes; and said coated wire passes alongside and in directly exposed relationship to said plurality of said ionization electrodes.
Claim 7
Dependent Claim
20 words
Ionization apparatus according to claim 4 and wherein a plurality of ionization electrodes are associated with each insulative housing member.
Claim 8
Dependent Claim
22 words
Ionization apparatus according to claim 4 and also comprising means for selectively energizing said plurality of ionization electrodes from a central location.
