Abstract: 1,241,104. Boron nitride. LOCKHEED AIRCRAFT CORP. 12 Aug., 1969 [19 Aug., 1968], No. 40363/69. Heading C1A. A boron filament is given a boron nitride surface coating, at least 0À1 Á thick, which is adherently bonded, and whose surface is continuous, by first forming a liquid boron oxide coating on the filament, and then converting this to the nitride by heating in a nitrogencontaining atmosphere. The preferred temp. for forming the oxide coating is within the range 560-1000‹ C. and the preferred temp. for nitriding is from 350-1100‹ C. The filaments thus prepared are for use as reinforcement in composite metal and metal alloy matrices. The liquid boron oxide coating may be prepared by heating the boron filament surface in an oxidizing atmosphere such as air, oxygen, or a mixture of oxygen with nitrogen or inert gas.

Abstract: 1,199,080. Boring earth &c. CHEVRON RESEARCH CO. 23 Aug., 1968 [24 Aug., 1967], No. 40528/68. Heading E1F. A sub-aqueous well having submerged wellhead equipment carried by casing is deepened by drilling apparatus suspended on the free end of a pipe extending from a reel mounted on a floating platform, the pipe and apparatus being fed to and removed from the well by a gripper supported on the hook of a travelling block. The well 15 is initially drilled and fitted with the casing and the wellhead equipment in accordance with the invention of Specification 839,499, the equipment including blowout preventers 89, 91, 99, a drilling head 101, and guides 73 extending to the platform 10. The platform has a removable rotary table 424 for the initial drilling. The reel 326 is driven by a motor 340 and has a pipe bender and level winder 327, the pipe 324 extending from the bender to the gripper 328 which is supported by the travelling block 31. Drawworks are operative to compensate for changes in elevation of the platform above the water bed to give a constant load on the drill bit, and include a winch drum 416 driven by a clutch 418 set to maintain a constant tension in the derrick line 422. The pipe is steel or aluminium comprises an inner tube having pins to centre it in an outer tube, the .fins adjacent the free end of the pipe connecting the tubes together. The drilling equipment comprises a bit 380, a "down-the-hole" motor 382 operated by drilling fluid to rotate the bit, collars 384, 386, a bumper sub 388, collars 390 392 and a member 394. The member 394 which may be a pump driven by a motor 412 operated by drilling fluid has openings 396 through which the drilling fluid passes to the annulus between the tubes of the pipe, fluid from the annulus passing through treatment apparatus 364 to a tank 360. Fluid from the tank is pumped by pump 356 to the inner tube of the pipe. The pressure in the hole below the drilling head is maintained slightly greater than the static pressure on the head to prevent dilution of the drilling fluid by water. The drilling equipment is guided to and from the well by a yoke engaging the guides and adapted to rest on the bit or the funnel 117 of the drilling head. Heavy drilling fluid from a tank 312 may be fed down a kill line 95 to the annulus between the drill pipe and the borehole.

To lift an object 12 without damaging it air is exhausted from a space 14 through a flexible tube 8 so that the object is held against a resilient pad 6. Air is now exhausted from the chamber formed by bellows 4 and plates 1, 5 through an orifice 2, thus causing the bellows to contract and the object to be lifted. By controlling the rate of flow of air to the bellows the object may be moved rapidly until it is almost touching the support on which it is being set down. Biasing means may assist the downward movement of the plate 5. The device may be used for lifting unfired crockery. Positive pressure may be applied to the space 14 when setting down the load.

Irradiated spherical fuel elements K comprising graphite-coated fuel particles embedded in a graphite matrix are heat-treated at a temperature 2500-3200‹ C. in a furnace comprising a graphite tube 1 disposed in a vacuum vessel 2 surrounded by an induction heating coil 6. The vessel 2 has air-locks 3, 4 and encloses a porous graphite heat insulation layer 5. Cleansing gas supplied through valves 7, 8 passes through the layer 5 and holes 11 in the tube 1. The heating causes a eutectic to form from the fuel particles, graphite and non-volatile decomposition products, the volatile decomposition products being conveyed by the cleansing gas through an aperture 12 into a porous graphite filter 14 in a gas-tight vessel 16. The filter 14 may be removed through an air-lock 13 by a device 17. The radio-active substances in the eutectic are removed by a halogenation process performed in a furnace similar to that of drawing, chlorine gas being mixed with, or replacing, the cleansing gas. The volatile compounds of the radio-active substances in the form of halides are collected in filters.

Abstract: 963,591. Ice-making. A/S ATLAS. Dec. 5, 1960 [Dec. 4, 1959], No. 41696/60. Heading F4H. An evaporator cooler comprises a cylindrical drum 1 which is cooled by the evaporation of a refrigerant in an annular space 28 defined by the drum 1 and a partition 16. Refrigerant vapour and entrained liquid from the space 28 pass over the upper edge of the partition 16 and strike a depending cylindrical baffle-plate 18, which serves as a liquid-vapour separator. The drum 1 is rotatable about its vertical axis and water is sprayed over its external surface from a perforated tube 13, the resultant ice film being removed by scrapers 11 and collected via a shoot 14. Liquid refrigerant is supplied to the drum through a pipe 22, the upper end 23 of which is bent to give a radial discharge of refrigerant on to a conical plate 17 whence it flows to space 28 through a pipe 20. Vapour returns to the compressor via an opening 27 in plate 17, a space 29, chamber 7 and pipe 26, the chamber 7 being provided with an outlet pipe 25 for liquid refrigerant which may be supplied to the chamber via an overflow pipe 24 in plate 17.
