Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
106 words
Apparatus for the static mixing of a fluid stream which comprises a pipe provided with at least one mixing insert comprising at least two plates provided with webs defining slots therebetween, the webs of one plate extending cross-wise through the slots of at least one other plate which is set at an angle to the first plate, said insert being suitable for insertion into the pipe to provide static mixing of the stream of fluid flowing in the pipe, the plates being inclined at an angle to the axis of the pipe, the circumferential surface of each plate fitting snugly against the wall of the pipe.
Claim 2
Dependent Claim
106 words
Apparatus for the static mixing of a fluid stream which comprises a pipe provided with at least one mixing insert comprising at least two plates provided with webs defining slots therebetween, the webs of one plate extending cross-wise through the slots of at least one other plate which is set at an angle to the first plate, said insert being suitable for insertion into the pipe to provide static mixing of the stream of fluid flowing in the pipe, the plates being inclined at an angle to the axis of the pipe, the circumferential surface of each plate fitting snugly against the wall of the pipe.
Claim 3
Dependent Claim
39 words
Apparatus as claimed in claim 1 in which the mixing insert comprises several plates, arranged in two rows, the webs of two plates of one row extending through the slots of at least one plate of the other row.
Claim 4
Dependent Claim
19 words
Apparatus as claimed in claim 2 in which the plates of each row are arranged parallel to each other.
Claim 5
Dependent Claim
37 words
Apparatus as claimed in claim 1 in which there are a plurality of said inserts, and the inserts are disposed so that the plates of adjacent inserts are displaced relative to each other in the circumferential direction.
Claim 6
Dependent Claim
16 words
Apparatus as claimed in claim 4, in which the displacement is by an angle of 90°.
Claim 7
Dependent Claim
10 words
Apparatus according to claim 4, wherein the plates are elliptical.
Claim 8
Dependent Claim
10 words
Apparatus as claim 1 in which the plates are elliptical.
Claim 9
Dependent Claim
17 words
Apparatus as claimed in claim 1, wherein the pipe is provided with a plurality of said inserts.
Claim 10
Dependent Claim
10 words
Apparatus according to claim 8, wherein the plates are elliptical.
Claim 11
Dependent Claim
51 words
Apparatus as claimed in claim 8, wherein the inserts are disposed so that the plates of adjacent inserts are displaced relative to each other in the angular direction by an angle of 90° and the plates of each insert are disposed in the gaps between the plates of the adjacent insert.
Claim 12
Dependent Claim
11 words
Apparatus as claimed in claim 10, wherein the plates are elliptical.
Claim 13
Dependent Claim
74 words
A mixing insert which comprises at least two plates provided with webs defining slots therebetween, the webs of one plate extending crosswise through the slots of at least one other plate which is set at an angle to the first plate, said insert being suitable for insertion into a pipe to provide static mixing of a stream of fluid flowing in the pipe and wherein the plates are provided with wwbs which taper stepwise.
Claim 14
Dependent Claim
74 words
A mixing insert which comprises at least two plates provided with webs defining slots therebetween, the webs of one plate extending crosswise through the slots of at least one other plate which is set at an angle to the first plate, said insert being suitable for insertion into a pipe to provide static mixing of a stream of fluid flowing in the pipe and wherein the plates are provided with wwbs which taper stepwise.
Claim 15
Dependent Claim
77 words
A mixing insert which comprises at least two plates provided with webs defining slots therebetween, the webs of one plate extending crosswise through the slots of at least one other plate which is set at an angle to the first plate, said insert being suitable for insertion into a pipe to provide static mixing of a stream of fluid flowing in the pipe in which the plates are in the form of combs and have elliptical circumferences.
Claim 16
Dependent Claim
77 words
A mixing insert which comprises at least two plates provided with webs defining slots therebetween, the webs of one plate extending crosswise through the slots of at least one other plate which is set at an angle to the first plate, said insert being suitable for insertion into a pipe to provide static mixing of a stream of fluid flowing in the pipe in which the plates are in the form of combs and have elliptical circumferences.
Claim 17
Dependent Claim
90 words
A mixing insert which comprises at least two plates in the form of combs provided with webs defining slots therebetween, the webs of one plate extending crosswise through the slots of at least one other plate which is set at an angle to the first plate, said insert being suitable for insertion into a pipe so that each plate makes contact all along its circumference inside of the pipe, and, being effective to provide static mixing of a stream of fluid flowing in the pipe by subdivision of the stream.
Claim 18
Dependent Claim
90 words
A mixing insert which comprises at least two plates in the form of combs provided with webs defining slots therebetween, the webs of one plate extending crosswise through the slots of at least one other plate which is set at an angle to the first plate, said insert being suitable for insertion into a pipe so that each plate makes contact all along its circumference inside of the pipe, and, being effective to provide static mixing of a stream of fluid flowing in the pipe by subdivision of the stream.
Claim 19
Dependent Claim
50 words
Apparatus for the static mixing of a fluid stream which comprises a pipe provided with at least one mixing insert as claimed in claim 14, the plates being inclined at an angle to the axis of the pipe, each plate making all around contact with the inside of the pipe.
Claim 20
Dependent Claim
40 words
Apparatus as claimed in claim 15 in which the plates are elliptical, and there are a plurality of said inserts disposed in a row extending along the axis of the pipe with the inserts in staggered relation to each other.
Claim 21
Dependent Claim
104 words
Apparatus for the static mixing of a fluid stream which comprises a pipe provided with at least one mixing insert which comprises a first group of spaced webs disposed so as to define slots between the webs, and a second group of spaced webs also disposed as to define slots between the webs, the webs of one of said groups extending crosswise through the slots of the other of said groups, said first and second group of webs being mounted in the pipe inclined at an angle to the axis of the pipe for static mixing of a fluid stream passed through the pipe.
Claim 22
Dependent Claim
104 words
Apparatus for the static mixing of a fluid stream which comprises a pipe provided with at least one mixing insert which comprises a first group of spaced webs disposed so as to define slots between the webs, and a second group of spaced webs also disposed as to define slots between the webs, the webs of one of said groups extending crosswise through the slots of the other of said groups, said first and second group of webs being mounted in the pipe inclined at an angle to the axis of the pipe for static mixing of a fluid stream passed through the pipe.
