Abstract: A seismic cable connector adapter assembly for coupling sub-diameter seismic streamer-cables to standard-sized instrumented cable connector modules.

Abstract: The rotatable cylindrical sleeve that comprises the female cable connector termination of a seismic streamer cable section is made in two telescoping parts. The two telescoping parts are indexed together by a shear pin to form a weak link assembly. If a streamer cable is snagged, the shear pin fails, allowing the telescoping parts of the sleeve to part company, releasing the snagged cable portions but without structural damage to the cable section. A feature of the device is its ease of retrofit.

Abstract: The process involves creating an internal lining in a bore, e.g., for repairing well casings. A plurality of layers of resilient strip material having an adhesive material, in uncured condition and interspersed between overlapping surfaces of the strip material and between the outer surface thereof and the bore, are applied in spiral fashion by means of a mandrel to the portion of the bore to be lined. Pressure is then applied to the internal surface of the liner to force the liner against the inner surface of the bore, preferably by inflation of a packer or packer assembly whose length is substantially the length of the liner, until the adhesive is cured. The mandrel for creating the liner in a bore includes a portion adapted to receive the spirally-wrapped strip material, a packer at the upper end of the wrappable portion of the mandrel and a packer terminating at the lower end of the wrappable portion of the mandrel and extending therebelow.

Abstract: Directed to a device for spreading an adhesive uniformly across a strip material comprising a container for strip to be coated, a pressurizable container for holding the adhesive, which is preferably a thermo-setting epoxy, a flexible tube connecting the adhesive container to an applicator head leading through a positive displacement meter. A feeder roll actuated by withdrawal of strip from the device operates the meter such that adhesive is applied only when strip is being withdrawn. The applicator head is provided with a slot through which adhesive is supplied from the interior of the applicator.
