Abstract
Abstract A device for controllably increasing the relative vapor content, particularly the humidity of a gas comprising, a body having a chamber with a sump in the lower portion, means for admitting fluid opening into said sump, disc means in said chamber rotatable with a sector of its marginal edge in said sump, means for rotating said disc at a speed which is sufficiently high to nebulize fluid within said chamber by the agitating action of the rotating disc member so as to increase the relative humidity of a gas passing through the chamber, inlet means opening into said chamber for admitting gas to said chamber and outlet means opening out of said chamber for withdrawing gas therefrom, said inlet and outlet means being disposed on opposite sides of said disc member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
191 words
A device for controllably increasing the relative humidity of a gas comprising, a body having a chamber with a sump in the lower pOrtion, means for admitting water opening into said sump, disc means in said chamber rotatable with a sector of its marginal edge in said sump, means for rotating said disc means at a speed which is sufficiently high to nebulize water within said chamber by the agitating action of the rotating disc means so as to increase the relative humidity of a gas passing through the chamber, said disc means extending substantially across the entire flow passage and having a plurality of apertures extending through the said body thereof and a plurality of substantially uniform recesses extending inwardly from the peripheral edge thereof at circumferentially spaced intervals to permit gas to flow from one side of said disc to the other by way of said apertures and recesses during rotation, inlet means opening into said chamber for admitting gas to said chamber and outlet means opening out of said chamber for withdrawing gas therefrom, said inlet and outlet means being disposed on opposite sides of said disc means.
Claim 2
Independent Claim
191 words
A device for controllably increasing the relative humidity of a gas comprising, a body having a chamber with a sump in the lower pOrtion, means for admitting water opening into said sump, disc means in said chamber rotatable with a sector of its marginal edge in said sump, means for rotating said disc means at a speed which is sufficiently high to nebulize water within said chamber by the agitating action of the rotating disc means so as to increase the relative humidity of a gas passing through the chamber, said disc means extending substantially across the entire flow passage and having a plurality of apertures extending through the said body thereof and a plurality of substantially uniform recesses extending inwardly from the peripheral edge thereof at circumferentially spaced intervals to permit gas to flow from one side of said disc to the other by way of said apertures and recesses during rotation, inlet means opening into said chamber for admitting gas to said chamber and outlet means opening out of said chamber for withdrawing gas therefrom, said inlet and outlet means being disposed on opposite sides of said disc means.
Claim 3
Dependent Claim
26 words
A device as claimed in claim 1 wherein a first ring of uniformly circumferentially spaced apertures is spaced inwardly from the peripheral edge of said disc.
Claim 4
Dependent Claim
42 words
A device as claimed in claim 2 wherein each of said apertures has an inlet orifice at one face of said disc and an outlet orifice at the other face of said disc, inlet orifice being substantially smaller than said outlet orifice.
Claim 5
Dependent Claim
26 words
A device as claimed in claim 2 where a second ring of uniformly circumferentially spaced apertures is located radially inwardly of said first ring of apertures.
Claim 6
Dependent Claim
52 words
A device as claimed in claim 4 wherein the outer peripheral edge of said disc is formed with a segmented circumferentially extending V-shaped groove extending radially inwardly a distance sufficient to open into said first ring of apertures, said first ring of apertures being substantially smaller than said second ring of apertures.
Claim 7
Dependent Claim
109 words
A device as claimed in claim 4 wherein each of said apertures has an inlet orifice and an outlet orifice, the inlet orifices of the apertures arranged in said second ring all being disposed at one side of said disc and the outlet orifices being disposed at the other side of said disc, the inlet and outlet orifices of each adjacent aperture in said first ring of apertures being disposed on opposite sides of said disc whereby the flow of gas through one orifice in the first ring of orifices is in a direction opposite to the flow of gas through adjacent orifices in the first row of orifices.
Claim 8
Dependent Claim
52 words
A device as claimed in claim 6 wherein the outer peripheral edge of said disc is formed with a segmented circumferentially extending V-shaped groove extending radially inwardly a distance sufficient to open into said first ring of apertures, said first ring of apertures being substantially smaller than said second ring of apertures.
Claim 9
Dependent Claim
34 words
A device as claimed in claim 1 having at least two disc members mounted for rotation in said chamber about a common axis of rotation, said discs being arranged in a spaced parallel relationship.
Claim 10
Dependent Claim
65 words
A device as claimed in claim 1 including feed water control means for controlling the flow of feed water to said sump to thereby control the amount by which the relative humidity of the gas is increased and speed control means for controlling the rotational speed of said disc means to thereby control the increase in relative humidity of the gas passing through the chamber.
Claim 11
Dependent Claim
18 words
The device of claim 1, wherein the rotating disc means is disposed essentially perpendicular to the gas flow.
Claim 12
Dependent Claim
34 words
A device as claimed in claim 10 having at least two disc members mounted for rotation in said chamber about a common axis of rotation, said discs being arranged in a spaced parallel relationship.
Claim 13
Dependent Claim
59 words
The device as claimed in claim 1 including baffle means and liquid trap means at said gas outlet means to prevent the passage of heavy particles of liquid from the chamber said baffle means extending to within close proximity of a rotating disc such that the fLow of liquid adjacent to the surface of the rotating disc is disrupted.
Claim 14
Dependent Claim
23 words
A device as claimed in claim 12 wherein the baffle means extends to within 3 millimeters of the surface of a rotating disc.
