Abstract: A method of manufacturing a flexible pipe that may include directing a first polymer composition through a first manifold and directing the first polymer composition along an outer surface of a metal tubular structure to form a first polymer tubular structure having an outer surface. Additionally, the method may include directing a second polymer composition through a second manifold and directing the second polymer composition onto the outer surface of first polymer tubular structure to form a second polymer tubular structure having an outer surface polymer tubular structure. Further, directing a third polymer composition through a third manifold and directing the third polymer composition onto the outer surface of second polymer tubular structure to form the flexible pipe. The flexible pipe includes a first layer made of the first polymer composition, a second layer made of the second polymer composition, and a third layer made of the third polymer composition.

Abstract: Disclosed is a pipe joint assembly comprising: a first and second pipe having smooth, essentially cylindrical ends; an elastomeric tape which is essentially triangular in cross-section, said tape having two surfaces, one of which is flat and the other of which tapers downward from its center to the edges of the tape; said elastomeric tape being wrapped around said first pipe adjacent one end of said first pipe with said flat surface of said tape being in contact with the outer surface of said first pipe; said first pipe having an outside diameter such that said first pipe fits matingly into one end of said second pipe with the elastomeric tape in contact with both the outer surface of said first pipe and the inner surface of said second pipe.

Abstract: An indent printer having a marking wheel with a plurality of printing heads operatively connected to the periphery thereof, at least one of the printing heads being adjustable to change printing type indicia and at least one support roller being spaced from the marking wheel, the circumference of the support roller being positioned relative to the marking wheel to support therebetween a moving substrate to be marked, and a method of adjustably marking are disclosed.

Abstract: A marine acoustical streamer cable having plural sections connected serially together with the streamer sections having connector couplers at opposite ends thereof adapted to be secured in mated relation without rotation to companion connector couplers of the same construction at the ends of adjacent streamer sections, each coupler comprising an axially elongated coupler body having a fully cylindrical anchoring head portion at one end and an axially elongated half cylindrical segment portion extending integrally from the anchoring head portion. The half cylindrical segment portions of the companion couplers when secured in mating relation collectively form a cylinder of the diameter of the streamer jacket.
