Abstract: For confidently coupling towed external devices to a marine seismic cable, a latch mechanism having a novel swing plate to improve the adjustability of the mechanism and provide a positive, clearly visible indication of latched and unlatched conditions. The swing plate serves as an external linkage between a rotatable adjustment head for a locking pin and a translatable lever arm for a locking rod. The locking pin and the locking rod extend from a latch housing on a towed device, such as a cable-leveling bird, and engage with a keyhole slot in a locking collar on the streamer. The swing plate engages the adjusting head, which protrudes from a side of the housing, in a push-nut engagement. Shoulders positioned approximately radially opposite each other on the swing plate push against the lever arm, which also protrudes from the side of the housing, as the adjustment head is rotated to completely extend or retract the locking rod into the mating slot, thereby locking or unlocking the mechanism as the lever arm is jammed to the top or the bottom of a guide slot. As the adjustment head is rotated to force the lever arm to the top or the bottom of the guide slot, a positive stop, which is clearly evident to an operator performing the adjustment, is provided. The structure of the swing plate, such as structure along a radial sector of the swing plate between the shoulders, is also used to occlude and reveal clearly visible indicia of a locked or unlocked mechanism as the swing plate is rotated.

Abstract: Release device for a cable used during seismic surveys at sea and towed through the water behind a vessel so that in the event of the occurrence of obstacles or other occasions when it is desirable to release the cable (1) from the towing vessel, a controlled release of the cable is possible so that it is not severed, but can be recovered for further use. At one or more locations in such cables release sections (2) are inserted which contain sensors which sense loading in the section and in the event of overloading or other occasions when release is desirable, an element (5) is activated which cause a release mechanism (6) to be activated and thereby causes a split in the cable (1) at a predetermined location.

Abstract: A large eddy break-up device for towed acoustic arrays for reducing the f noise due to the (TBL) around the towed array is described. It includes two identical halves, each having a circumferential airfoil and two flat flanges which are used to secure it to a coupling on the towed acoustic array and also to integrate the two halves using fasteners. The circumferential foil interferes with the flow noise and large eddys are broken up into easily dissipating small eddys of higher frequency.

Abstract: A transducer array designed for towing at an extended distance behind a sace vessel includes electroacoustical transducer elements connected in opposition to the active elements of the array. A surrounding acoustic isolation structure effectively isolates the dummy transducer elements from the ambient noise field while permitting cancellations of self-induced noise.

Abstract: The disclosure concerns a directional hydrophonic antenna, consisting of several pairs of dipoles formed by omnidirectional hydrophones superimposed in a streamer and keeping the same reference angle for all the pairs of dipoles. The goal sought is achieved by means of a chain of superimposed, directional modules each bearing a hydrophonic sensor on each lateral face and joined by ringed tubular elements through which there goes a central rod made of fiber glass and a strand of electrical connection cables.
