Title: Improvements in and relating to the making of zirconium chloride
IPC: C01G25/04
Filed: 1954-10-25
Abstract: <PICT:0759724/III/1> Zirconium chloride is prepared by fluidizing a mass of a zirconium ore, preferably zircon, in the presence of carbon with gaseous chlorine at a temperature such that chlorination occurs, suitably between 800 DEG  and 1100 DEG C and condensing the chloride formed from the gaseous reaction product.  When zircon is employed a 4:1 by weight ratio of zircon to carbon is preferred but greater amounts of carbon may be employed if an oxygen containing gas is fed to the reaction chamber to supply heat by carbon combustion.  The reaction zone may be indirectly heated for example by an electric furnace or the mixture of oil and carbon or the chlorine gas may be preheated.  In the drawings, Fig. 2, a fluidized mass of zircon and carbon is maintained in a silica reaction tube 5 by feeding the ore/carbon mixture through hopper 40 and fluidizing the bed by chlorine gas fed through line 28 from a source 32.  The centre part of the reaction zone is surrounded by an electric furnace 6 containing silicon carbide resistance heating elements 9.  Gaseous reaction products leave the furnace through an arm 44 which is surrounded by a packed ceramic fibre layer 48 in which is embedded a heating coil 50 to maintain the arm 44 at 325 DEG  to 350 DEG C.  The reaction products pass into condenser 4 where zirconium chloride precipitates, deposition on the walls being prevented by a vibrator 58; uncondensed reaction products pass through line 55 to a further condenser 62 where silicon tetrachloride is precipitated.  In operation, before the passage of chlorine gas, the apparatus is swept by a nitrogen stream fed from a container 31 and the thus fluidized mass of zircon and carbon is heated to about 1000 DEG C before the nitrogen is replaced by chlorine from source 32.  The feed line 39 from the hopper 40 is heated by means not shown, to prevent clogging of the line by deposition of sublimed zirconium chloride.  At the close of the operation the chlorine stream is substituted by nitrogen and the electric furnace removed.  When the temperature has dropped to about 300 DEG  to 400 DEG C the nitrogen is turned off and the condensers 4 and 62 are removed and replaced by a calcium chloride drying tube to prevent moisture being drawn into the system as it cools.  The process is applicable to other zirconium ores such as zirkite or baddeleyite.

Title: Dump bailer and bridge plug for use in well bores
Inventor: BAKER REUBEN CARLTON
IPC: E21B27/02
Filed: 1950-12-18
Abstract: 682,742. Well-plugging tools. BAKER OIL TOOLS, Inc. Dec. 18, 1950, No. 30818/50. Class 85 A well plugging tool comprises positively secured together in combination a packer unit 11, dump bailer C and a setting tool F. The shaft 10 of the packer unit is surrounded by a packer 17 positioned between expanders 16, 18 the tapered surfaces 15 of which engage complementary tapered ribs 13, 21 formed on slip sleeves 12, 22, the sleeve 12 being confined between the expander 16 and a nose portion 11 screwed on to the shaft 10 whilst the sleeve 22 is confined between the expander 18 and an abutment 23 in a central bore of which is a spring locking ring 24. The inner surface of the ring 24 has formed thereon teeth 25 which may slide downwards over teeth 26 formed on the shaft 10 but engage and lock with said teeth if an attempt is made to move the abutment 23 upwards. To set the packer, this abutment 23 is moved downwards relative to the shaft 10, so forcing downwards the expander 18 to break the slip sleeve 22 into segments that engage the wall of the casing and so prevent further downward movement of the abutment 23. The shaft 10 is now drawn upwards relative to the abutment 23, causing the compression and setting of the packer 17, and the breaking of the slip sleeve 12 into segments and engagement thereof with the casing. The abutment 23 forms the bottom closure of a cylinder 34 filled with cement D that is inserted through an opening 38 in the cylinder which is connected to the piston rod 54 of the electrically-detonated gas-operated setting tool F by components 38, 39, 40 and 55, whilst the shaft 10 of the packer is connected to the cylinder 51 of the setting tool by tension stud 46 and tubular members 45, 43, 41. On the ignition of the slowburning gas-producing charge 58 in the cylinder 51, the piston 53 is forced downwards, the piston 54 transmitting this movement by means of the crosspiece 55, which slides vertically in slots 42 formed in the tubular mandrel 41, to the cylinder sleeve 39 and thence to the cylinder 40 which moves abutment 23 downwards to set the upper slip segments of the packer. When this is done and downward movement of the abutment 23 of the piston 53 is arrested, the cylinder 50 moves upwards causing the shaft 10 to do likewise, so completing the setting of the packer. When the packer is set, tension on the stud 46 increases as the charge 58 continues to burn until the stud 46 parts at the waist 47. The setting tool and sleeve can now be removed from the bore, the cement discharging from the cylinder on to the packer as it is raised clear of the abutment 23.

Abstract: <PICT:0785398/III/1> <PICT:0785398/III/2> In the boiler shown, water or other fluid flowing through tube banks 36 is heated by the fluidized bed 14 in which the banks are immersed.  The particles of the bed comprise a catalytic material and fuel entering the base of the bed through a pipe 32, a distributer 30 and perforated pipes 34 is oxidized, and consequently consumed, solely by the catalytic oxidation action of the bed material.  The material is kept at a catalytically active temperature by heating the air which maintains the bed in a fluidized condition.  For this purpose air is forced by a blower 17 up through the bed - entering the latter through a perforated base-plate 12-after being heated to a desired temperature by a burner 18 which is supplied with fuel and air through valve - controlled lines 20, 22 respectively.  Gaseous, liquid or pulverized fuel may be supplied to the bed through pipe 32.  The water or fluid to be heated is passed to the banks 36 through tubes 42 from a header 38 which is divided into three sections each communicating with a fluid feed conduit 44 through a valve 46.  Each tube 42 is provided with a metering device at its inlet. The heated fluid flows from the banks 36 through further tubes 42 to a header 40.  The banks 36 are connected to the headers so that the direction of fluid flow across the bed through adjacent banks is respectively reversed.  The combustion gases arising from the bed may be conveyed over additional heat exchange surface or passed through a fluidized bed of inert material within which a heat exchange surface is disposed.  The combustion gases may be passed through a cyclone separator. Particles of fused silica, sands, clays, &c. may be added to the fluidized catalytic bed. The material forming the bed may comprise activated forms of metal oxides such as alumina, beryllia, thoria, zirconia, or magnesia, or mixtures of these oxides, impregnated with minor amounts of finely divided metals such as platinum, palladium, rhodium, ruthenium, silver, copper, chromium, manganese, nickel, cobalt, or combinations of these metals such as a silverchromium, copper - chromium, copper - manganese combination.  Gamma alumina may be prepared from natural bauxite by removing the impurities such as iron and silicates then heating at a temperature below about 2000 DEG F. to drive off the combined water.  The amount of metal when impregnating with a silver-chromium combination to form a suitable catalyst is from 2 per cent to 5 per cent by weight based on the weight of the activated metal oxide.  In a described example, a bed consists of pellets of activated alumina impregnated with 0.2 per cent by weight of platinum, the pellets being in the shape of cylinders having a diameter and length of about 0.086 inch.
