Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
185 words
Jacketing for underwater cables, ropes, drag ropes, etc., with streamline profile comprised of two completely separable profiled strips for individual reeling, each having a first surface to be placed into abutment with the first surface of the respective other first strip and each strip having a second surface disposed symmetrical to a plane defined by the first surfaces when placed in abutment to each other, to establish a streamline profile, resulting joints between the strips as exposed extending along leading and trailing edges of the streamline profile; the strips each having at least one recess open to the first surface, the recesses having location and contour complementary to each other to define an elongated cavity for loosely receiving the rope or cable when the first surfaces are in mutual abutment; first fastening means on the strips in the first sUrfaces thereof for releasably interconnecting the two strips between the cavity and the leading edge of the profile; and second fastening means on the strips in the first surfaces thereof for releasably interconnecting the two strips between the cavity and the trailing edge of the profile.

Claim 3
Dependent Claim
29 words
Jacketing as in claim 1, the fastening means each including overhung ridges and mating overhung grooves in and of the first surfaces and in complementary configuration to each other.
Claim 4
Dependent Claim
55 words
Jacketing as in claim 2, the first fastening means including an overhung groove in a first one of the two strips and a mating overhung ridge on the other one of the two strips, the second fastening means including an overhung groove in the other strip and a mating overhung ridge on the first strip.
Claim 5
Dependent Claim
47 words
Jacketing as in claim 1, the strips having plural recesses each in the first surfaces thereof to provide plural elongated cavities upon interconnecting the strips to each other, the recesses and resultant cavities extending over the entire length of the strips for receiving plural ropes and/or cables.
Claim 6
Dependent Claim
12 words
Jacketing as in claim 4, the recesses defining cavities of different diameters.
Claim 7
Dependent Claim
27 words
Jacketing as in claim 1, there being additional complementary recesses in the first surfaces of the strip to define limited space cavities for receiving pieces of equipment.
Claim 8
Dependent Claim
24 words
Jacketing as in claim 1, the strips having skeleton construction with closed cavities not open to the first and second surfaces, and providing buoyancy.
Claim 9
Dependent Claim
13 words
Jacketing as in claim 7, the closed cavities being filled with a foam.
Claim 10
Dependent Claim
33 words
Jacketing as in claim 1, the recesses located so that the center of gravity of the assembled jacket is about the same with or without load bearing cable or rope in the cavity.
Claim 11
Dependent Claim
10 words
Jacketing as in claim 1, the strips made of plastic.
Claim 12
Dependent Claim
12 words
Jacketing as in claim 10, the strips made of fiber reinforced plastic.
Claim 13
Dependent Claim
13 words
Jacketing as in claim 1, the jacket reducing in cross-section throughout its length.
