Title: Improved apparatus for drawing glass tubing and rod
Inventor: MACKAY DONALD
IPC: C03B17/04
Filed: 1960-10-27
Abstract: <PICT:0943236/C1/1> In the drawing of glass tubing or rod 7 from a sleeve of softened glass formed on an inclined rotating mandrel 1, the sleeve of glass is tooled, as by a roller 8, with a light resilient pressure against the glass, in the lower half of its length during rotation of the mandrel so as to render the sleeve wall thickness more uniform.  The ceramic mandrel 1 has a tip 2 of corrosion-resistant metal and is secured to a hollow shaft for rotation therewith, the shaft acting as a blow-pipe when tubing is being produced, the whole being enclosed in a muffle 12 suitably heated as by gas burners and having a sliding door 13 and a steel door 14 with lining 15 of refractory material, the rod or tube 7 passing through an opening 16.  The atmosphere in the muffle is of nitrogen to prevent oxidation of the graphite of the roller 8.  As shown, the roller 8 is carried in a gimbal 17 in a yoke 18 on the end of a long tube 19 pivoted at 20 near its mid point and guided at 21 to prevent lateral displacement. A slidable counterweight 22 gives light pressure of the roller 8 on the glass.  In an alternative construction, the roller 8 is mounted in a yoke at the end of a water-cooled arm with counterweight.

IPC: C01B33/08
Filed: 1957-11-27
Abstract: 864,538. Metal halides prepared electrolytically. BRITISH TITAN PRODUCTS CO. Ltd. Oct. 31, 1958 [Nov. 27, 1957], No. 37034/57. Class 41. In a process for making halides of tetravalent metals and silicon electrolytically, in which the electrolyte consists of molten alkali metal or alkaline earth metal halide, the anode consists of carbon mixed with the oxide of silica or the metal with which halogen formed at the anode combines to form the tetra halide. The process applies particularly to silica used in the form of quartz, tridymite or siliceous material, e.g. zircon silicates, or bauxite, but zircon dioxide as baddelyite is also specified. This may be finely ground with petroleum coke or charcoal, a binder, e.g. gum, pitch, glycerine or de, hydrated castor oil, compressed to form a rod which is then fired. Alternatively the powdered siliceous material is filled into a porous pot with a carbon rod inserted therein. In a suitable apparatus, molten MgCl 2 , 2, is contained in a vessel 1 provided with a carbon or tungsten cathode 5, and a carbon rod anode 21 immersed in a mixture of carbon and silica 8 surrounded by a silica tube 9. The electrolyte is maintained at 700‹ to 1400‹ C. using a thermocouple 4, and an inert gas fed into a tube 13 carries off the SiCl 4  produced to an outlet 14. Magnesium metal is deposited on the cathode, and forms a pool under the molten MgCl 2 . As the anode is consumed, additions are made of a pasty mixture of carbon, siliceous material and binder, which is baked in the cell. The anode mixture contains about 30% of carbon. Other electrolytes used are CaCl 2 , NaCl and KCl mixture, LiCl, and BeCl 2 . Specifications 745,051, 763,931 and 796,735 are referred to.

Abstract: 1361700 Fuel elements COMMISSARIAT A L'ENERGIE ATOMIQUE 11 Aug 1972 [12 Aug 1971] 37615/72 Heading G6C A nuclear fuel assembly for use in a sodiumcooled fast reactor comprises at least one bundle of elongate fuel pencils disposed parallel to one another within a shroud, the shroud consisting of two sections 34, 36 disposed end-to-end and connected by a joint allowing angular displacement of the sections relative to one another. The assembly illustrated in Fig. 1, comprises two superposed bundles, the pencils 20 in the lower bundle being of the "integrated" kind (i.e. containing a fission gas collection chamber in region 22, a column of pellets of fertile material in region 24, a column of pellets of fissile material in region 26, and finally a space allowing the latter column to expand upwards) and borne by a grid 21 while the pencils 30 in the top bundle, which are suspended from a grid 32, are filled with pellets of fertile material. The top section 36 of the shroud may be thinner than the bottom section 34 and slightly overlaps this latter section at its lower end while enclosing an annular neutron shield 18 at its upper end. The two sections are connected to one another by a rod 38 provided with a gripping head 40 and replacing the central fertile pencil in the top bundle. The rod 38 is secured by three fins 42 to the upper end of section 36 and by three fins 44 to the upper end of section 34. In order that the rod 38 can bend freely, without contacting fertile pencils, it is surrounded by a thin jacket 46 of hexagonal cross-section. The rod 38 may be replaced by a tube which takes the place of not one but seven fertile pencils. With either of these arrangements, the deformation under irradiation shown by the dashed line for a unitary shroud is reduced to the amount shown by the chain-dotted line. In alternative embodiments, the fuel assembly is limited to a single bundle of "integrated" pencils housed in the bottom section of the shroud (Fig. 2, not shown) and the two sections of the shroud are connected by a flexible toroidal diaphragm (Fig. 3, not shown). In further embodiments, the two sections are connected by a ball and socket joint provided with a labyrinth seal (Fig. 4, not shown), or by a Cardan joint in which case sealing-tightness is obtained by thin metal plates secured to one section and pressed against the other section by the pressure of the coolant flowing through the shroud (Fig. 5, not shown). In yet another embodiment (Fig. 6, not shown), the two sections are connected by a rod in two parts joined by a ball and socket joint and each secured to one of the sections.

Abstract: 1386207 Electro-chemical analysis T E  LARSON R W LANE and C H NEFF 14 Aug 1973 [18 Aug 1972] 38450/73 Heading G1N [Also in Division G3] The amount of a weak acid or a weak base (e.g. a buffer) is measured by reacting the sample with an excess amount of strong base or strong acid reagent respectively, measuring the conductivity of the reagent treated sample and comparing the measured conductivity to a standard value. In the arrangement of Fig. 2 (not shown) the base buffer ingredient in a slightly buffered alkaline water source e.g. in a boiler condensate return line 21 is measured. A sample of the condensate is withdrawn through valve 22 and fed via constant head device 23 and pre-heater 28 to a mixing tee 29 where it is mixed with a controlled proportion of a strong acid reagent from 31 which is in excess of the amount required to react with all of the buffer ingredient. A constant flow-rate of the heated sample is then heated to boiling in chamber 34 to degas the sample and then passed to conductivity cell 40. Comparator 41 compares the measured value of conductivity with a standard which may be obtained by shutting off the flow of sample and passing de-ionized water from 46 through the system. The conductivity of the de-ionized water and reagent is measured and the standard in the comparator adjusted by means of a variable resistor until the measured value and standard are balanced. Alternatively a standard buffer solution may be used in place of the de-ionized water. The difference im conductivities between the sample and standard indicates the deviation of the boiler condensate buffer content from the standard and the signal from the comparator may be used to control the addition of buffer from buffer supply 47 to the condensate stream. For confirmatory purposes a second controlled amount of reagent may be added at 29' and the conductivity measured at 40'. The boric acid concentration in a solution used as a neutron absorber in a nuclear reactor may be measured by injecting a small amount of sample into a stream of the reagent and measuring the conductivity Fig. 4 (not shown). In this apparatus the reagent flow is split into two parallel paths and the sample is injected into one of the paths. The outputs from two conductivity cells mounted in respective paths are compared. The principles of the method are described with reference to an arrangement wherein an NaHCO 3  sample is injected into a stream of demineralized water which then passes through a first conductivity cell. An excess amount of H 2 SO 4  is then added and after passing through a sparging chamber is fed to a second conductivity cell. Examples of acid reagents are sulphuric, hydrochloric, nitric, phosphoric sulphurous, dichloroacetic, maleic, picnic, naphthalenesulphonic, oxalic and trichloroacetic. Base reagents may be alkali metal hydroxides, acetamides, pyrazine and urea.
