Abstract
Abstract A self-contained, fluid impregnated, high voltage, electric power cable or cables extending between a fixed point underwater and a movable platform, such as the deck of a barge floating on such water, the cable or cables being surrounded by a series of interconnected rigid pipes having interconnections which permit limited tilting of the axis of one pipe with respect to the axes of the next adjacent pipes so as to avoid bending of the cable or cables which would damage the electric characteristics thereof.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
150 words
High voltage electric cable apparatus extending between a predetermined point to a movable structure having a high voltage, electric power generating plant thereon, said apparatus comprising at least one self-contained, fluid impregnated, high voltage cable comprising an inner conductor surrounded by insulation and a fluid impervious, flexible, metal sheath, said cable being constructed to permit bending thereof including said sheath by a predetermined amount without damage to the electrical characteristics thereof and said cable being electrically connected at one end to said plant, and a plurality of rigid pipes connected in series and surrounding said cable from substantially said point to substantially said structure, saiD pipes being connected to each other by connections permitting tilting of the axis of one pipe with respect to the axis of the next adjacent pipe but preventing tilting thereof by an amount which will cause bending of said cable to exceed said predetermined amount.
Claim 2
Dependent Claim
150 words
High voltage electric cable apparatus extending between a predetermined point to a movable structure having a high voltage, electric power generating plant thereon, said apparatus comprising at least one self-contained, fluid impregnated, high voltage cable comprising an inner conductor surrounded by insulation and a fluid impervious, flexible, metal sheath, said cable being constructed to permit bending thereof including said sheath by a predetermined amount without damage to the electrical characteristics thereof and said cable being electrically connected at one end to said plant, and a plurality of rigid pipes connected in series and surrounding said cable from substantially said point to substantially said structure, saiD pipes being connected to each other by connections permitting tilting of the axis of one pipe with respect to the axis of the next adjacent pipe but preventing tilting thereof by an amount which will cause bending of said cable to exceed said predetermined amount.
Claim 3
Dependent Claim
25 words
Apparatus as set forth in claim 1, wherein a plurality of said cables are surrounded by said pipes, said cables being secured to each other.
Claim 4
Dependent Claim
56 words
Apparatus as set forth in claim 2, wherein said cables are secured to each other by a plurality of spiders spaced from each other lengthwise of said cables, each of said spiders having a plurality of apertures therein, one for each said cable, which receive said cables, and means for holding said cables in said apertures.
Claim 5
Dependent Claim
40 words
Apparatus as set forth in claim 1, wherein the interior cross-section of said pipes is larger than the exterior cross-section of said cable to thereby provide space between the interior wall of said pipes and the exterior of said cable.
Claim 6
Dependent Claim
15 words
Apparatus as set forth in claim 1, wherein each of said connections is fluid pervious.
Claim 7
Dependent Claim
55 words
Apparatus as set forth in claim 1, wherein each of said connections comprises a projection at at least one end of each pipe extending in the circumferential direction and means on the end of the next adjacent pipe for loosely engaging said projection and limiting tilting movement thereof with respect to said next adjacent pipe.
Claim 8
Dependent Claim
44 words
Apparatus as set forth in claim 6, wherein said means on the end of the next adjacent pipe comprises a channel extending in the circumferential direction and receiving said projection with the walls of said channel spaced, at least in part, from said projection.
Claim 9
Dependent Claim
71 words
Apparatus as set forth in claim 7, wherein said channel has radially extending side walls and a bottom wall extending in the circumferential direction and said side walls of said channel are spaced apart in the lengthwise direction of the pipe a distance greater than the dimension of said projection in the lengthwise direction of the pipe and said bottom wall has a radial dimension different from that of said projection.
Claim 10
Dependent Claim
30 words
Apparatus as set forth in claim 8, wherein one of said side walls is on a ring having a threaded connection with the end of the pipe having said channel.
Claim 11
Dependent Claim
43 words
Apparatus as set forth in claim 6, wherein said means on the end of the next adjacent pipe comprises a second projection on said last-mentioned end extending in the circumferential direction and coupling means loosely coupling said second projection to said first-mentioned projection.
Claim 12
Dependent Claim
36 words
Apparatus as set forth in claim 10, wherein said coupling means comprises a ring having at least one channel extending around said projections, the dimensions of said channel being greater than the dimensions of said projections.
Claim 13
Dependent Claim
39 words
Apparatus as set forth in claim 10, wherein said coupling means comprises a plurality of rods extending between said projections, each of said rods being movable to a predetermined extent with respect to at least one of said projections.
Claim 14
Dependent Claim
22 words
Apparatus as set forth in claim 1, wherein said point is underwater and said structure is a structure floating on said water.
Claim 15
Dependent Claim
56 words
Apparatus as set forth in claim 13, wherein said cable is fixed in position at said point and extends from said point in a direction opposite from the direction in which it extends to said structure to a further point above water which is fixed in position and wherein said cable is secured to said structure.
Claim 16
Dependent Claim
29 words
Apparatus as set forth in claim 1, wherein said connections limit the tilting of the axis of one pipe with respect to the other to a maximum of 10*.
