The method extends to the fixing of a member, e.g. manifold, "tee" section, into an existing underwater pipeline in which ease the pileline is cut, and the ends emptied of water by means, e.g. of a pipeline pigs sphere before raising to a support above the surface where the member, and if necessary, an additional pipe piece, is installed before relowering to the waterbed in the described manner. As shown (Fig. 3a) pipe ends 3, 9 are raised by barge cranes 7, 10 in conjunction with buoyancy tanks 8 to the water surface where smaller cranes 14 haul the pipes into inverted U support brackets 22 (Fig. 6) which provide a movable coupling to the barge. A line-up frame 17 (see Fig. 8) having hydraulic gripping jaws 18, 19 hold the pipe ends in alignment for e.g. welding, and the continuous pipe section so formed is lowered in alternate lateral and vertical step increments to the water bottom whereupon buoyancy tanks 8 are flooded to allow the pipe to settle in an unstressed condition. In an alternative method, the pipe ends are lifted to the surface to be within 45 degrees of the vertical and the ends joined above the waterline by a suitable junction piece, e.g. a U section, before lowering as described. The pipes to be joined preferably lie in overlapping relationship upon the waterbed before joining to provide the excess length required to bring the ends into juxtaposition at the surface.

Abstract: 1,273,804. Semi-conductor devices. NATIONAL AERONAUTICS & SPACE ADMINISTRATION. 25 Aug., 1969 [19 Sept., 1968], No. 42278/69. Heading H1K. [Also in Division G1] In an electromechanical transducer comprising a body of piezo-resistive material having means for creating an electric field along the longitudinal axis of the body and means connected to a pair of lateral surfaces for sensing the voltage changes produced by a mechanical force applied to the body, the lateral surfaces are skewed with respect to a main crystallographic axis of the body. As shown, Fig. 4, a body of Ge or Si is provided with end contacts to which a voltage source 23 is connected to provide a biasing field in the body and symmetrically arranged contacts on its lateral (major) faces from which the output is taken. The force is applied along the longitudinal axis and produces a voltage at the lateral contacts by virtue of a combination of the piezo-resistive and "pinch" effects. The body is arranged so that the longitudinal axis of the lateral surfaces are skewed with respect to the crystalline axes o the material, Fig. 1. The "pinch" effect can be enhanced by giving the upper and lower lateral faces of the body high and low surface recombination velocities respectively. A low recombination velocity may be achieved by diffusing impurities into the surface to form a more highly doped layer defining an L-H junction which prevents current carriers from reaching the surface.
