Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
216 words
A fluid-tight connector for elements of floating pollution containment booms comprising disconnectible elements including at least one floating pollution containment boom, at least one of the elements being secured along substantially the entire extent of a vertical edge of said pollution containment boom, complimentary slides on the ends of each of the elements, at least one of said slides including: a pair of flanges parallelplanar with the plane of and extending from the end of said element to form a groove therebetween; and transverse members on the free ends of said flanges, said transverse members having rearward faces on each side thereof disposed to form an angle of less than 90° with the plane of said element and to partially close the opening in the groove formed by said flanges, said flanges being of a thicknss substantially equal to the width of said opening, said transverse members and flanges forming tongues which, when inserted into the groove of a corresponding slide, are configured to form a fluid-tight connection between elements, and said transverse members and flanges including means to direct resultant transverse forces imposed on the flanges forming the groove inwardly through reaction on the abutting rearward faces and to block withdrawal of said tongue from said groove in directions other than parallel to said groove.
Claim 2
Dependent Claim
216 words
A fluid-tight connector for elements of floating pollution containment booms comprising disconnectible elements including at least one floating pollution containment boom, at least one of the elements being secured along substantially the entire extent of a vertical edge of said pollution containment boom, complimentary slides on the ends of each of the elements, at least one of said slides including: a pair of flanges parallelplanar with the plane of and extending from the end of said element to form a groove therebetween; and transverse members on the free ends of said flanges, said transverse members having rearward faces on each side thereof disposed to form an angle of less than 90° with the plane of said element and to partially close the opening in the groove formed by said flanges, said flanges being of a thicknss substantially equal to the width of said opening, said transverse members and flanges forming tongues which, when inserted into the groove of a corresponding slide, are configured to form a fluid-tight connection between elements, and said transverse members and flanges including means to direct resultant transverse forces imposed on the flanges forming the groove inwardly through reaction on the abutting rearward faces and to block withdrawal of said tongue from said groove in directions other than parallel to said groove.
Claim 3
Dependent Claim
18 words
A connector in accordance with claim 1 wherein both of said slides comprise a pair of said flanges.
Claim 4
Dependent Claim
16 words
A connector in accordance with claim 2 wherein said slides are fabricated of a flexible material.
