Abstract
Abstract A wave guide flange assembly comprises male and female flanges on the cooperating ends of a pair of tubular conductors to be connected in end-to-end relationship with there being a number of axial openings uniformly spaced in the female flange. A bolt is partially threaded into each of said axial openings, and a clamping unit has a bore through which the bolt passes. A clamping unit is provided for each bolt, and the bore may be slotted so that the clamping unit slides radially into locking engagement with an annular shoulder on the male flange. The clamping unit may have an eccentric shape so that rotation thereof will cause a portion to lockingly engage with the annular shoulder. The clamping unit may also comprise pairs of clamping blocks interconnected by tie bars.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
147 words
A wave guide flange assembly for connecting tubular conductors in end-to-end relationship, and comprising a male flange having an annular shoulder thereon and secured to an end of one tubular conductor, a female flange secured to an end of another tubular conductor and receiving said male flange therein, a plurality of circumferentially spaced independently movable pairs of clamping means, each of said clamping means having outwardly extending slots therein, fastener means passing through each of said slots and held in one of said flanges, each of said clamping means being movable relative to its fastener means, and a tie bar means pivotally connecting each pair of said clamping means together, so that each pair of said clamping means can be radially slid independently of other pairs relative to its fastener means into and out of locking engagement with the annular shoulder on the other of said flanges.
Claim 2
Dependent Claim
147 words
A wave guide flange assembly for connecting tubular conductors in end-to-end relationship, and comprising a male flange having an annular shoulder thereon and secured to an end of one tubular conductor, a female flange secured to an end of another tubular conductor and receiving said male flange therein, a plurality of circumferentially spaced independently movable pairs of clamping means, each of said clamping means having outwardly extending slots therein, fastener means passing through each of said slots and held in one of said flanges, each of said clamping means being movable relative to its fastener means, and a tie bar means pivotally connecting each pair of said clamping means together, so that each pair of said clamping means can be radially slid independently of other pairs relative to its fastener means into and out of locking engagement with the annular shoulder on the other of said flanges.
Claim 3
Dependent Claim
170 words
A wave guide flange assembly for connecting tubular conductors in end-to-end relationship, and comprising a male flange having an annular shoulder thereon and secured to an end of one tubular conductor, a female flange secured to an end of another tubular conductor and receiving said male flange therein, said female flange having an even number of substantially uniformly circumferentially spaced axial openings therein, clamping means movably mounted on said female flange, said clamping means comprising a pair of clamps for each pair of flange openings with each clamp having a slot therein and having a portion engageable with said male flange shoulder, the slots of each pair of clamps being parallel and cooperating with corresponding openings in said female flange, a tie bar interconnecting said pair of clamps into a unit, and fastener means passing through corresponding slots and flange openings so that each interconnected pair of clamps can be moved radially upon loosening of said fastener means with respect to the tubular conductors to connect and disconnect the same.
Claim 4
Dependent Claim
170 words
A wave guide flange assembly for connecting tubular conductors in end-to-end relationship, and comprising a male flange having an annular shoulder thereon and secured to an end of one tubular conductor, a female flange secured to an end of another tubular conductor and receiving said male flange therein, said female flange having an even number of substantially uniformly circumferentially spaced axial openings therein, clamping means movably mounted on said female flange, said clamping means comprising a pair of clamps for each pair of flange openings with each clamp having a slot therein and having a portion engageable with said male flange shoulder, the slots of each pair of clamps being parallel and cooperating with corresponding openings in said female flange, a tie bar interconnecting said pair of clamps into a unit, and fastener means passing through corresponding slots and flange openings so that each interconnected pair of clamps can be moved radially upon loosening of said fastener means with respect to the tubular conductors to connect and disconnect the same.
Claim 5
Dependent Claim
23 words
A wave guide assembly as claimed in claim 2 wherein the annular shoulder on said male flange faces away from the female flange.
Claim 6
Dependent Claim
26 words
A wave guide flange assembly as claimed in claim 3 wherein said clamp has a lip thereon engageable with the annular shoulder on said male flange.
Claim 7
Dependent Claim
22 words
A wave guide flange assembly as claimed in claim 2 wherein said fastener means comprises a pin having a circular cross section.
