Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 98 words
Apparatus for projecting ionized air comprising: a tube of conductive material having a series of ionizing points extending therefrom; means for connecting said tube with a source of compressed air and with a source of alternating current; air passage means extending through the wall of said tube for directing air generally along said points; grounded shield means of conductive material about said tube and having outlet apertures for air from within said tube; each said point terminating substantially within a said aperture; and additional aperture means for admitting atmospheric air into the space between the tube and shield.
Claim 2
Dependent Claim 98 words
Apparatus for projecting ionized air comprising: a tube of conductive material having a series of ionizing points extending therefrom; means for connecting said tube with a source of compressed air and with a source of alternating current; air passage means extending through the wall of said tube for directing air generally along said points; grounded shield means of conductive material about said tube and having outlet apertures for air from within said tube; each said point terminating substantially within a said aperture; and additional aperture means for admitting atmospheric air into the space between the tube and shield.
Claim 3
Dependent Claim 17 words
The apparatus of claim 1, and insulating means supporting said tube and shield means in spaced relationship.
Claim 4
Dependent Claim 17 words
The apparatus of claim 1, said points being in a line and, axially spaced along said tube.
Claim 5
Dependent Claim 17 words
The apparatus of claim 3, there being at least two said air passages between each two points.
Claim 6
Dependent Claim 20 words
The apparatus of claim 1, the axes of said points, said apertures and said air passage means being substantially parallel.
Claim 7
Dependent Claim 16 words
The apparatus of claim 1, said additional aperture means comprising inlet apertures in said shield means.
Claim 8
Dependent Claim 34 words
The apparatus of claim 1, said inlet apertures being in a row and said outlet apertures being in a row, the apertures of one row being diametrically opposite the apertures of the other row.
Claim 9
Dependent Claim 21 words
The apparatus of claim 7, wherein the axes of said points, said apertures and said air passage means are substantially parallel.
Claim 10
Dependent Claim 144 words
Apparatus for projecting ionized air comprising: a tube of conductive material, a tubular shield of conductive material surrounding said tube, said shield having a first series of radially extending apertures therein, and a second series of apertures each diametrically opposed to an aperture of said first series, insulator means mounting said tube substantially concentrically within said shield, a row of points electrically connected with said tube and extending therefrom, said points being axially spaced along said tube and each terminating substantially within a said aperture of said first series, air passages extending through said tube and directed generally toward the apertures of said first series, said tube having one end closed and having at the other end means for connection to a source of air under pressure, means for connecting said tube to a source of alternating current, and means for grounding said shield.
