Title: Method and apparatus for making submerged pipeline connections
IPC: F16L37/00
Filed: 1970-03-23
Abstract: 1300771 Pipe laying; pipe couplings BROWN & ROOT Inc 23 March 1970 [7 May 1969] 13931/70 Headings F2G and F2P An underwater pipe-line 28 and an offshore platform riser pipe are coupled by an end section 38; slidable inside the end 44 of the pipeline and mating with an end part 20 of the riser. Two methods of coupling the pipe-line 28 and riser are: (a) the riser is clamped to the offshore platform, the pipe-line is laid underwater toward the riser until the pipe-line end 44 is approximately aligned with the riser with the slidable part 38 retracted, and the part 38 is brought, by a drawline or diver, into engagement with the riser end 20; (b) the slidable part 38 is coupled to the riser end 20 on a barge, the coupled riser and pipe-line are lowered on to the sea bed, with the riser approximately aligned with the offshore platform and the slidable part 38 mid-way between extended and retracted positions, the riser being then clamped to the platform, the final alignment being aided by movement of the part 38 with respect to the pipe-line. The slidable part 38 is accepted in a bell mouth housing at the riser end 20 and is locked in position by spring-biased, radially movable pins 172 with teeth 168 mating with grooves in the part 38. The part 38 is guided by a drawline pulling a stopper 42 locked in part 38 by springbiasedpins 222 (Fig. 6). Upon mating of the part 38 with the riser end 20, fluid is introduced into the stopper 42, by flooding the riser or by a separate control pipe, to operate pistons 226 and thereby retract the pins 222 from the head 154 of the part 38 so as to unlock the stopper prior to its removal. The part 38 is alternatively coupled to riser end 20 by bolted abutting flanges, Fig. 7 (not shown), separated by a sealing ring, the flange for the riser end being rotatable relative to the riser for alignment of the bolt holes prior to coupling. After the pipe-line and riser have been coupled and positioned, the slidable part 38 is locked in position within, the pipe-line end 44 by toothed ring segments 104, normally held free by circlips 112, operated by a fluid controlled piston 98 to close on the part 38 by travelling down the tapered surface 118 of a ring 116. The ring 116 also compresses resilient rings 126, 128 and a rubber ring 124 to fill the gap between parts 38, 44. Cementitious material is poured into the gaps between parts 38, 44 through ports 90a, 134, 136. The ring segments 104 are, alternatively, manually operated by a flanged ring screwed into pipe-line end 44 transmitting thrust to the piston through thrust balls.

Title: Improvements in or relating to methods of crystallizing from melts
IPC: B22C9/26
Filed: 1954-05-14
Abstract: The solute concentration in single crytals, e.g. of semi-conductor material grown from the melt by the Czochralski method is maintained uniform by pulling the crystal from a pool of melt of constant volume, the pool being replenished as the crystal is pulled by material having the same solute concentration as the crystal.  If this concentration is very low the replenishing material may be substantially pure.  As described, the main bulk 6 of the material, e.g. germanium, having the solute concentration required in the grown crystal is <PICT:0754767/III/1> placed in an outer crucible 1.  A closely fitting inner crucible 2 floats on the material 6 which can flow into the inner crucible through a channel 3 in the base of the inner crucible to form a pool 7.  A furnace 8 keeps the material molten.  A seed 15 is supported by a rotatable holder 16 and the seed and pool 7 can be gradually moved apart by means of an hydraulic jack 23 which lowers the furnace assembly.  The growing space is surrounded by a box in which an atmosphere of hydrogen, helium or nitrogen may be maintained.  The solute concentration in the pool 7 is initially adjusted by adding solute by a tube 14 so that the ratio of the solute concentration in the pool 7 to the desired solute concentration in the grown crystal is equal to the liquid/solid partition coefficient and growing is started and may be continued until the reserve material in the pool 6 is exhausted.  During growth the crystal may be rotated, e.g. at 100 r.p.m.  In an example N-type germanium is grown using antimony as solute, the furnace temperature being varied from 971 DEG  to 961 DEG C. to maintain uniform crystal cross-section and the growth rate being 0.04 inches per minute maintained for 52 minutes.  Hydrogen was passed through the growing space at 50 cc. per minute.  The resistivity of the grown crystal was substantially constant.  A modified form of crucible is described in Fig. 3 (not shown) and it is stated that a single crucible may be used divided into two communicating compartments.  Specification 706,849 is referred to.

Abstract: 1,246,045. Preparing microscope specimens. PERKIN-ELMER CORP. March 18, 1969 [March 19, 1968], No. 14203/69. Heading G2J. A method and apparatus is described for producing a thin layer of blood for analysis. A motor 1 has a hollow output shaft 3 which drives a flywheel 4 and is coupled through a clutch 5 to a shaft 6 which drives a platform 7. One end of shaft 6 is hollow and communicates with a cavity in the surface of the platform. The cavity may be evacuated through line 8, bushing 9 and port 10, and a blood reception plate 11, e.g. a glass cover slip or a transparentplastics slip, may then be secured on the platform by suction. Some blood 12 is then deposited and the motor started, and when flywheel 4 has reached the required speed clutch lever 14 is depressed. Plate 11 is then quickly accelerated to the speed of the motor and the spinning motion causes the majority of the blood to leave the plate and strike shield 13, but there is left on the plate a thin layer which is completely monocellular and also substantially uniform in cell distribution. The plate is finally removed, inverted and attached to a microscope slide.
