Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
48 words
A submersible vehicle for tow and control from a surface vessel comprising an umbilical cable coupled to said surface vessel and at least two similar opposed paraboloids of revolution sealed at the line formed by their joining, said opposed paraboloids including two pairs of piggy-back paraboloids of revolution.
Claim 2
Dependent Claim
48 words
A submersible vehicle for tow and control from a surface vessel comprising an umbilical cable coupled to said surface vessel and at least two similar opposed paraboloids of revolution sealed at the line formed by their joining, said opposed paraboloids including two pairs of piggy-back paraboloids of revolution.
Claim 3
Dependent Claim
82 words
An oceanographic body for use on moored or free floating systems as a stable platform comprising at least two similar opposed sealed paraboloids of revolution normally ballasted with the paraboloidal axes oriented in a vertical plane, said platform further comprising pivotal means coupled to at least one paraboloidal face for mooring said platform, the paraboloidal axes being horizontally oriented and said pivotal means comprising a V-shaped member coupled to opposing paraboloidal faces edgewise removed from the center of gravity of said platform.
Claim 4
Dependent Claim
82 words
An oceanographic body for use on moored or free floating systems as a stable platform comprising at least two similar opposed sealed paraboloids of revolution normally ballasted with the paraboloidal axes oriented in a vertical plane, said platform further comprising pivotal means coupled to at least one paraboloidal face for mooring said platform, the paraboloidal axes being horizontally oriented and said pivotal means comprising a V-shaped member coupled to opposing paraboloidal faces edgewise removed from the center of gravity of said platform.
