Abstract: A non-rotating depth controller paravane for seismic cable streamers wherein the paravane includes a body having a central bore extending the length thereof through which the seismic cable extends with the paravane latched in non-rotatable relation to the seismic cable. The paravane includes three or more pivotally mounted diving planes, four being shown in the illustrated example, and electronic circuitry and servo means for sensing differences between a command signal and a depth indicating signal derived from a pressure transducer on the paravane and activating the servo system to position the diving planes to cause the paravane to climb or dive regardless of its orientation about the roll axis and without movement of the paravane in yaw. Gravity sensing potentiometers vary the control signals to the servo system to activate the diving planes in this manner regardless of the orientation of the paravane about the roll axis.

Abstract: A multi-section marine seismic streamer construction wherein each streamer section has identical couplers at opposite ends. The couplers have a partly separable cylindrical end portion interfitted in the streamer outer jacket and clamped about a strain cable anchor head and an end portion of a trunk cable running through the section. The couplers also have semicylindrical portions to mate with like portions of campanion couplers along a diametric plane of the streamer, with male and female electrical plugs in plug cavities in the mating portions coupled together, and mounting bolts perpendicular to the diametric plane securing the mating portions together.
