Abstract

Abstract A static eliminator including a channel-shaped bar entirely enclosed in an insulating sheath: the sheath has a slot in and extending parallel to the channel, the slot at its inner end terminating in a cylindrical bore in which is a metal tube. Ionizing points penetrate into the metal tube and extend through the slot, and contacts are provided to the bar and tube from ground and to a source, respectively.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 119 words
A static eliminator comprising: a longitudinally extending metal bar having a cross-section of channel shape, a sheath of insulating material on said bar, said sheath encompassing substantially all longitudinal surfaces of said bar, a longitudinally extending slot entering said sheath and extending into said channel shape bar and terminating in a generally cylindrical bore separated from said bar by said insulating material sheath, a longitudinal member of conductive material in said bore, a plurality of spaced, parallel ionzing points in said slot, said points being of conductive material and extending into and engaging said member, and means connecting said longitudinal member of conductive material to a source of electric potential and means for connecting said metal bar to ground.
Claim 2
Dependent Claim 119 words
A static eliminator comprising: a longitudinally extending metal bar having a cross-section of channel shape, a sheath of insulating material on said bar, said sheath encompassing substantially all longitudinal surfaces of said bar, a longitudinally extending slot entering said sheath and extending into said channel shape bar and terminating in a generally cylindrical bore separated from said bar by said insulating material sheath, a longitudinal member of conductive material in said bore, a plurality of spaced, parallel ionzing points in said slot, said points being of conductive material and extending into and engaging said member, and means connecting said longitudinal member of conductive material to a source of electric potential and means for connecting said metal bar to ground.
Claim 3
Dependent Claim 11 words
The static eliminator of claim 1, wherein said bar is aluminum.
Claim 4
Dependent Claim 14 words
The static eliminator of claim 1, wherein said sheath is of rigid polyvinyl chloride.
Claim 5
Dependent Claim 20 words
The static eliminator of claim 1, wherein said sheath has an insulating value of at least 600 volts per mil.
Claim 6
Dependent Claim 19 words
The static eliminator of claim 1, wherein said bore has a diameter greater than the width of said slot.
Claim 7
Dependent Claim 29 words
The static eliminator of claim 1, said member comprises a conductor, a metal tube having said conductor therein, said metal tube engaging said insulating sheath material defining said bore.
Claim 8
Dependent Claim 15 words
The static eliminator of claim 6, and means for securing said conductor to said tube.
Claim 9
Dependent Claim 28 words
The static eliminator of claim 7, said last mentioned means comprises at least one of said ionizing points, said means extending through said tube and into said conductor.
Claim 10
Dependent Claim 47 words
