Abstract: A fluid filled marine seismic streamer employs a plurality of hydrophones spaced apart along its length to detect seismic reflection signals from subsurface formations below a water layer. A plurality of fluid blocking members are also spaced apart along the length of the streamer. A plurality of flow through spacers having varying flow through apertures are positioned between each hydrophone adjacent to a fluid blocking member that generates pressure pulses in the fill fluid of significant magnitude to be detected by such hydrophone. The size of the flow through apertures of such spacers progressively increases in a direction leading from the fluid blocking member toward the hydrophone.

Abstract: A marine cable for detecting converted shear waves reflected from the strata beneath a body of water in response to a compressional wave generated in the body of water. The cable comprises a jacket, a mount attached to the stress member, a geophone positioned in the mount, a first weight assembly attached to the stress member and positioned proximate a first end of the mount and a second weight assembly positioned proximate a second end of the mount. The mount is sized and made of a material so that its weight is sufficient to cause at least the portion of the cable jacket that is adjacent the mount to contact the seafloor. The first and second weight assemblies are sized and made of material so that their respective weights cause at least the portion of the cable jacket that is adjacent to the respective weight assemblies to contact the seafloor.

Abstract: Methods and means are provided for detachably interconnecting electrical components in an electrical system located and used in a disadvantageous environment. An improved connector device is provided which is composed of spaced-apart metallic terminals embedded in a substantially rectangular body member and adapted to be electrically joined with leads in a cable or the like. One pin-end portion of each terminal is located in a sidewall recess in the body member, and the other socket-like end portion of the terminal projects into and through a plug-like extension from the body member opposite the sidewall recess containing the pin-like end portion. Two or more such connectors may be stacked together in a fluid-tight manner, by inserting the plug-like projections from the block of one connector into the sidewall recesses in the block portion of another connector, whereby the socket-like ends of the terminals in the first connector receive the pin-like ends of the terminals in the other block member, and also whereby any water or other electrically conductive fluid on the connections will be prevented from creating an electrically conductive path between the terminals therein.

Abstract: A differential charge amplifier design for a hydrophone pre-amplifier inces a calibration circuit for in situ measurement of the hydrophone/pre-amplifier gain. The hydrophone signal is input to a pair of amplifier stages which form a balanced differential input charge amplifier. The signal from the input charge amplifier is amplified by a second pre-amplifier stage and then passed to a balanced output cable driver. The calibration circuit is enabled by an external signal to inject a calibration signal into the input charge amplifier front end.

Abstract: In accordance with an illustrative embodiment of the present invention, a fish-net plastic sheath having oppositely layed, generally parallel plastic filaments is used to cover the conductor wire bundle at points where it could otherwise rub against the wire rope strain members of the cable. The filaments are joined at all crossing points to provide an expansible and contractible generally tubular construction that can be readily fitted over cable bundle during assembly. The sheaths prevent the wire rope strain cables in the streamer sections from rubbing directly against the conductor wires and causing holidays in the insulation and resulting shorts.

Abstract: Sensors mounted in detachable modules are located at selected positions along a cable, such as one used in marine seismic exploration, adapted to be towed behind a vessel in a body of water. The sensors are selectively addressable, either individually or as a group, by coded signals sent through the cable. When addressed, the sensors provide readings of the earth's magnetic field vector. The readings are used to provide an indication of the position of the sensors and thus the cable relative to the towing vessel. Cable depth readings may also be made by the sensors.

Abstract: An optical fiber hydrophone system in which a single optical fiber is used for all of the acoustical sensors in the system. A signal source and detector provides an optical signal in selected form, such as continuous or pulsed and detects and extracts an identifiable output signal. Each sensor is in the form of a sensing portion of the single optical fiber. Each sensing portion includes two optical reflectors separated one from another by a predetermined length of said optical fiber. Variations in acoustical pressure incident on the sensing portion causes a change in the predetermined length. This causes reflected portions of the optical signal to interfere with one another. Such interference is detectable for extraction of the identifiable output signal. In one form each sensing portion has two terminal branches of a mechanically deformable material, deformable in response to the fluctuations in acoustical pressure. Preferably, the optical fiber has two portions, a sensing portion thereof underwater and having a first optical cavity, and another portion thereof on board a vessel and having a second optical cavity, typically tunable with respect to the optical length thereof to maximize the interference in the detected optical signal.
