Title: Marine riser system and method for installing the same
IPC: E21B7/128
Filed: 1975-12-30
Abstract: 1526239 Boring earth &c SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 30 Dec 1975 53144/75 Heading E1F When drilling offshore from a floating platform 9 using a marine riser 8 connected at its lower end to the wellhead 10 and at its upper end to a heave compensating system (13 to 16) on the platform 9, an inner riser 19 can be located concentrically within the outer riser 8 and sealed thereto at its top and bottom, the pressure of the fluid within the annulus 22 between the risers 8, 19 being equalised with the pressure outside the outer riser 8. This arrangement reduces the buckling forces exerted on the outer riser 8 as the density of the drilling mud is increased and the diameter of the borehole is decreased. As described the lower end of the outer riser 8 is connected to the wellhead 10 through a flexible joint 11 and a remotely detachable coupling 12 and the upper end is connected to the cables 14, 14' of a heave compensating system, a telescopic member 17 with a flexible joint 17A being provided between the outer riser 8 and platform 9. The riser 8 is also provided with buoyancy members 18. The inner riser 19 is sealed to the outer riser 8 at A and B. At its lower end B the riser 19 is fixed to a housing 60 (Fig. 3) which is originally located in the lower end 63 of the outer riser 8 by keys 61 engaging grooves 62, 62A and is then locked in position by locking dogs 67 which are moved inwardly by wedges 68 operated by hydraulic rams 70. The housing 60 is sealed to the outer riser by packer 72. At its upper end A the riser 19 is a sliding fit in housing 30 (Fig. 2) which is fixed to the outer riser 8 by keys 31 and locking dogs 34, the housing 30 being sealed to the inner riser 19 by packers 39, 40 and to the outer riser 8 by packer 48. When the inner riser 19 is being lowered into the outer riser 8, the housing 30 is temporarily fixed to the riser 19 by pins 175 engaging J-slots 174. The inner riser 19 is provided with buoyancy members 23. In a modification (not shown) the inner riser 19 is tensioned by an hydraulic piston and cylinder arrangement provided at the upper seal A.  The pressure inside annulus 22 is equalised with the pressure outside of riser 8 by opening valves 24, 25 thus allowing the drilling mud to flow out and sea water to flow in. The valves 24. 25 may be opened before or after the inner riser 19 is placed in position.

In a three-gun three colour picture tube having a luminescent screen comprising, for example, the colour strips 6-8, and a postfocusing grid adjacent the screen, the screen being provided with a thin aluminium coating 5 and a graphite layer 4 deposited on the aluminium coating, the graphite layer is porous and has a density d gm/cm<SP>3</SP> and a thickness e microns such that the produce d, e lies between 2À6 and 5À1. The graphite serves to reduce secondary electron emission which reduces the contrast, and the range given produces an improvement in contrast without excessively reducing the brightness by reducing the energy of the primary electrons. Preferably d lies between 0À2 and 0À3 and e lies between 13 and 17. The layer may be formed by spraying a colloidal suspension of graphite grains in ethyl alcohol, the grains having a diameter of about 1 micron. To this suspension is added a filmforming material such as a collodion or a methyl methacrylate which is eliminated during subsequent heat treatment phases in the preparation of the screen.

Spherical graphite fuel elements for use in high-temperature nuclear reactors and comprising fuel particles mixed with graphite mass and an amount of binder, are cold pressed in a silicone rubber mould within a steel pressing die, which mould is cylindrical in exterior shape and divided into two symmetrical halves axially or radially and is provided with an ellipsoidal cavity which is deformed to spherical shape during cold pressing at high pressures of up to 7 tons/cm.2 The powder is consolidated to three to five times its original density and occluded air is removed by vent grooves provided in the rubber mould and steel die or by pressing in vacuo. To protect the fuel particles on the surface from damage, the fuel particle containing element is surrounded by a thin, particle free shell of the same graphite as the matrix of the fuel containing core which is initially pre-pressed semi.hydrostatically in rubber moulds at a low pressure of 20/kg./cm.<SP>2</SP> preferably to provide a grooved surface; the prepressed core is then enclosed within prepressed half shells of graphite powder. Improved heat dissipation from the fuel particles may be obtained with a fuel containing intermediate layer between a fuel free core and outer shell. After pressing, the binder is coked by heating the element at 1,000‹ C. in an inert gas followed by heating in vacuo at 1600 to 2,000‹ C. whereby oxidation resistance, impact strength and thermal conductivity are improved. The semi-hydrostatic pressing improves strength and isotropy over that obtained in a steel die. In addition to pure fuel particles (coated UC 2 - or UO 2 -particles), fertile material particles in which uranium is completely or partly replaced by thorium, or burnt up poison particles (with B 4 C for example) may be introduced.

Title: A method and apparatus for cutting a sample from a moving sheet of material

IPC: D21G9/00
Filed: 1967-12-12
Abstract: 1,215,947. Cutting samples. INDUSTRIAL NUCLEONICS CORP. 12 Dec., 1967 [12 Dec., 1966], No. 56475/67. Heading B4B. A method of cutting a sample from a web 11, Fig. 4, of material as it passes along a predetermined path in the direction of its length comprises moving a pair of convergent cutting edges 14, 15 through the web as it travels along the path so that as the edges move through the web, cuts 37, 38, Fig. 9, are formed which diverge from a first common point in the web, and then withdrawing the edges from the web so that the cuts converge to a second common point so severing a sample of the web from the remainder of the web between said cuts. In an apparatus for performing the method, the cutting edges 14, 15 are formed on crossed blades 12, 13 which are carried on a support 16, Fig. 4, which is mounted for vertical reciprocation under the control of an air cylinder 24 and piston 25. The support 16 also carries a tongue 32 which deflects the sample via a shoot 28 into a receptacle 35 releasably attached to the shoot. In other embodiments, the cutting edges are formed on a single cutter of inverted V-shape and may be mounted on a swingable arm instead of the vertically reciprocable support. The assembly including the blades 12, 13, support 16, and cylinder 24, may be mounted on rails so as to be movable transversely of the web thus enabling a sample to be taken at any position across the width of the web, or a sample to be taken which extends obliquely of the web. Instruments which measure characteristics of the web in the vicinity of the sample may be mounted on the rails for movement with the cutter assembly so that subsequent measurement of characteristics of the sample enables calibration of these instruments to be checked.
