Abstract
Abstract A gas scrubber for removing contaminants from gas including constricting flow passage means for said gas, a plurality of elongated filter elements in parallel extended transversely across said flow passage means and defining therebetween a plurality of smaller, separate, discrete flow paths for high velocity gas flow. The first set of said elements is mounted in fixed relation relative to said flow passage and a second set of elements comprising alternate ones between adjacent elements in said first set is supported for movement relative to said elements in the first set to vary the size of said discrete flow paths therebetween. Means is provided for adjusting and holding the relative position of the elements in the first and second sets, thereby defining a selected total flow area for accommodating a given rate of gas flow.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
135 words
A gas scrubber for removing contaminants from gas including a constrictive flow passage for said gas; a plurality of elongated filter elements in parallel extended transversely across said passage defining a plurality of separate, discrete flow paths for high velocity gas flow; a first set of said elements mounted in fixed relation to said flow passage; a second set of said elements comprising alternate ones between adjacent elements in said first set; support means carrying said second set of elements and mounted for movement relative to said flow passage toward and away from elements in said first set to vary the area of said flow paths; and holding means for positioning said support means for maintaining said second set of elements in a selected spaced relation with respect to said elements of said first set.
Claim 2
Dependent Claim
135 words
A gas scrubber for removing contaminants from gas including a constrictive flow passage for said gas; a plurality of elongated filter elements in parallel extended transversely across said passage defining a plurality of separate, discrete flow paths for high velocity gas flow; a first set of said elements mounted in fixed relation to said flow passage; a second set of said elements comprising alternate ones between adjacent elements in said first set; support means carrying said second set of elements and mounted for movement relative to said flow passage toward and away from elements in said first set to vary the area of said flow paths; and holding means for positioning said support means for maintaining said second set of elements in a selected spaced relation with respect to said elements of said first set.
Claim 3
Dependent Claim
57 words
The gas scrubber of claim 1 wherein said support means includes pairs of guide surfaces between said elements in said first set for limiting movement of said elements of said second set to maintain substantially equal spacing between an element of said second set and each element in an adjacent pair of elements in said first set.
Claim 4
Dependent Claim
53 words
The gas scrubber of claim 2 wherein said support means includes a movable frame supporting said elements of said second set from opposite ends, and means mounting said frame for movement toward and away from said elements of said first set with said elements supported by said frame Disposed between said guide surfaces.
Claim 5
Dependent Claim
32 words
The gas scrubber of claim 3 including pivot link means connected to said movable frame for supporting the same for parallel movement toward and away from the elements in said first set.
Claim 6
Dependent Claim
24 words
The gas scrubber of claim 4 wherein said pivot link means are pivotable about axes fixed relative to said elements in said first set.
Claim 7
Dependent Claim
29 words
The gas scrubber of claim 4 including a fixed frame supporting said elements of said first set, said pivot link means pivotally interconnected between said fixed and movable frames.
Claim 8
Dependent Claim
45 words
The gas scrubber of claim 4 wherein said holding means is operatively interconnected to adjust and hold the relative pivotal position of said pivot link means and said movable frame to provide said selected spaced relation between said elements of said first and second sets.
Claim 9
Dependent Claim
17 words
The gas scrubber or claim 7 wherein said holding means comprises force exerting means of adjustable length.
Claim 10
Dependent Claim
28 words
The gas scrubber of claim 3 including a fixed frame supporting said first elements from opposite ends thereof, said fixed frame including means defining said guide surfaces therein.
Claim 11
Dependent Claim
40 words
The gas scrubber of claim 9 wherein said elements of said first set are supported for free axial rotation in said fixed frame and said elements of said second set are supported for free axial rotation in said movable frame.
Claim 12
Dependent Claim
38 words
The gas scrubber of claim 10 wherein said movable frame includes a plurality of guides defined thereby supporting opposite ends of said elements carried thereby and permitting limited translation of said elements normal to their own longitudinal axes.
Claim 13
Dependent Claim
25 words
The gas scrubber of claim 11 wherein said guide surfaces of said fixed frame are angularly disposed relative to said guides of said movable frame.
