Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
142 words
An assembly of interconnected conduits comprising: a first cylindrical conduit having an aperture extending through its wall thickness; a second cylindrical conduit disposed adjacent said first cylindrical conduit having an aperture extending through its wall thickness; and coupling means interconnecting said apertures formed as a unitary member having a first wall surface contoured as a cylindrical portion for mating with said first cylindrical conduit and a second, opposed wall surface also contoured as a cylindrical portion for mating with said second cylindrical conduit, said wall surfaces being separated by a thickness through which a substantially unobstructed passage extends, said passage being aligned with said apertures, said first and second conduits being separated by said wall thickness, means for sealing and securing said unitary member to said conduits and for permitting fluid flow through said passage between said first and second cylindrical conduits.
Claim 2
Dependent Claim
142 words
An assembly of interconnected conduits comprising: a first cylindrical conduit having an aperture extending through its wall thickness; a second cylindrical conduit disposed adjacent said first cylindrical conduit having an aperture extending through its wall thickness; and coupling means interconnecting said apertures formed as a unitary member having a first wall surface contoured as a cylindrical portion for mating with said first cylindrical conduit and a second, opposed wall surface also contoured as a cylindrical portion for mating with said second cylindrical conduit, said wall surfaces being separated by a thickness through which a substantially unobstructed passage extends, said passage being aligned with said apertures, said first and second conduits being separated by said wall thickness, means for sealing and securing said unitary member to said conduits and for permitting fluid flow through said passage between said first and second cylindrical conduits.
Claim 3
Dependent Claim
20 words
The assembly of claim 1 wherein said wall surfaces are aligned with their cylindrical axes generally parallel to each other.
Claim 4
Dependent Claim
17 words
The assembly of claim 1 wherein said wall surfaces are aligned with their cylindrical axes being nonparallel.
Claim 5
Dependent Claim
14 words
The assembly of claim 1 wherein said wall surfaces face away from each other.
Claim 6
Dependent Claim
26 words
The assembly of claim 1 wherein said first and second conduits are secured to their respective wall surfaces on said member by means of an adhesive.
Claim 7
Dependent Claim
18 words
The assembly of claim 1 wherein said first and second conduits are dimensioned with different cross-sectional outer peripheries.
Claim 8
Dependent Claim
13 words
The assembly of claim 1 wherein said passage is defined by a bore.
