Abstract
Abstract An ion-cell having an elongated hollow body having an inlet at one end and an outlet at the other for the passage of a stream of compressed air therethrough, a wall located downstream of the inlet having a central opening therein, a conductive sleeve or lining secured in the central opening, an electrode member supported in the body between the inlet and wall member, and means for inducing an ion field between the electrode and the conductive sleeve to saturate the gas stream.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
167 words
Apparatus for the ionization of a gas stream comprising an elongated hollow body having a conductive inlet part at one end and an outlet part at the other end along a common longitudinal axis, a wall in said body located downstream of said inlet part and upstream of said outlet, said wall having a conductive sleeve defining a central opening therein, a first elongated electrode member supported along the common longitudinal axis and spaced between said inlet part and said wall sleeve, means for connecting said electrode and the sleeve to a source of voltage to thereby induce electrical 360* arcing between said electrode and inlet part and said electrode and said sleeve to produce corona fields of ion particles therebetween, and said inlet being adapted for connection to a source of gas under pressure whereby said gas may be caused to flow from said inlet to said outlet through said fields of ion particles becoming charged thereby with a balanced composition of positive and negative ions.
Claim 2
Dependent Claim
167 words
Apparatus for the ionization of a gas stream comprising an elongated hollow body having a conductive inlet part at one end and an outlet part at the other end along a common longitudinal axis, a wall in said body located downstream of said inlet part and upstream of said outlet, said wall having a conductive sleeve defining a central opening therein, a first elongated electrode member supported along the common longitudinal axis and spaced between said inlet part and said wall sleeve, means for connecting said electrode and the sleeve to a source of voltage to thereby induce electrical 360* arcing between said electrode and inlet part and said electrode and said sleeve to produce corona fields of ion particles therebetween, and said inlet being adapted for connection to a source of gas under pressure whereby said gas may be caused to flow from said inlet to said outlet through said fields of ion particles becoming charged thereby with a balanced composition of positive and negative ions.
Claim 3
Dependent Claim
21 words
The apparatus according to claim 1 wherein said body is cylindrical and said parts, wall and electrode are coaxially located therein.
Claim 4
Dependent Claim
20 words
The apparatus according to claim 2 wherein said electrode extends within the interior of said inlet and said conductive sleeve.
Claim 5
Dependent Claim
27 words
The apparatus according to claim 2 wherein the wall opening is of substantially smaller diameter than the diameter of the body to thereby constrict the passage therethrough.
Claim 6
Dependent Claim
67 words
The apparatus according to claim 4 including a second electrode member located downstream between said sleeve and the outlet part, the outlet part being conductive, the second electrode being located along the axis of said body and being insulated therefrom thereby to freely transmit ion-emission to said outlet by an induced 360* arcing between said sleeve and second electrode and said second electrode and said outlet part.
Claim 7
Dependent Claim
37 words
The apparatus according to claim 1, and at least a constricted orifice adjacent said inlet for the entry of ambient gas into said body in response to the movement of gas from said inlet to said outlet.
Claim 8
Dependent Claim
27 words
The apparatus according to claim 5 wherein said electrodes are needle like members, symmetrically formed with a taper at each end and a generally circular cross section.
Claim 9
Dependent Claim
24 words
The apparatus according to claim 7 wherein the ends of the electrode members are flattened into a plane substantially transverse to their longitudinal axis.
Claim 10
Dependent Claim
102 words
Apparatus for ionizing a gas stream comprising a body for passing a gas in an axial direction from an inlet having a conductive part to an outlet, means having a conductive element for constricting the passage of the gas along said axis within said body, electrode means between said inlet part and said conductive element for creating 360* ion corona fields therebetween and substantially within the area of constriction, said corona field between said electrode and part and element substantially saturating said area and charging a gas passing from said inlet to said outlet with a composition of positive and negative ions.
Claim 11
Dependent Claim
102 words
Apparatus for ionizing a gas stream comprising a body for passing a gas in an axial direction from an inlet having a conductive part to an outlet, means having a conductive element for constricting the passage of the gas along said axis within said body, electrode means between said inlet part and said conductive element for creating 360* ion corona fields therebetween and substantially within the area of constriction, said corona field between said electrode and part and element substantially saturating said area and charging a gas passing from said inlet to said outlet with a composition of positive and negative ions.
Claim 12
Dependent Claim
43 words
The apparatus according to claim 9 wherein said electrode is a needle like member, symmetrically formed to a dimension at its opposite ends narrower than at its center, and said ends each extends into overlying relation with said conductive part and element respectively.
