Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
90 words
In an interfacial surface generator which comprises a plurality of flow dividing and diverting elements, the elements being adapted to be inserted within a conduit and provide diversion and re-arrangement of a stream flowing therein to provide increased interfacial area between stream components, each of the elements being supported by at least one support means, the improvement which comprises providing a demountable joint between at least some of the adjacent elements, wherein the demountable joint is a threaded coupling which threadably engages terminal portions of the dividing and diverting elements.
Claim 2
Dependent Claim
90 words
In an interfacial surface generator which comprises a plurality of flow dividing and diverting elements, the elements being adapted to be inserted within a conduit and provide diversion and re-arrangement of a stream flowing therein to provide increased interfacial area between stream components, each of the elements being supported by at least one support means, the improvement which comprises providing a demountable joint between at least some of the adjacent elements, wherein the demountable joint is a threaded coupling which threadably engages terminal portions of the dividing and diverting elements.
Claim 3
Dependent Claim
87 words
In an interfacial surface generator which comprises a plurality of flow dividing and diverting elements, the elements being adapted to be inserted within a conduit and provide diversion and re-arrangement of a stream flowing therein to provide increased interfacial area between stream components, each of the elements being supported by at least one support means, the improvement which comprises providing a demountable joint between at least some of the adjacent elements, wherein the demountable joint comprises a pin passing through portions of adjacent dividing and diverting elements.
Claim 4
Dependent Claim
87 words
In an interfacial surface generator which comprises a plurality of flow dividing and diverting elements, the elements being adapted to be inserted within a conduit and provide diversion and re-arrangement of a stream flowing therein to provide increased interfacial area between stream components, each of the elements being supported by at least one support means, the improvement which comprises providing a demountable joint between at least some of the adjacent elements, wherein the demountable joint comprises a pin passing through portions of adjacent dividing and diverting elements.
Claim 5
Dependent Claim
21 words
The generator of claim 2 wherein the demountable joint comprises at least one link extending between adjacent dividing and diverting elements.
