Title: Gas Filtering Installation
Inventor: BRION JACQUES
IPC: B01D50/00
Filed: 1967-07-24
Abstract: 1,183,211. Gas filter. COMMISSARIAT A L'ENERGIE ATOMIQUE. 24 July, 1967 [9 Aug., 1966], No. 33956/67. Heading B1T: A filter for removing radioactive solids from incinerator effluent gas comprises a set of filtering tubes 4 through which the gas is fed from inlet 1 to outlet 2, the tubes being lined with a loose layer of asbestos fibres which are periodically removed, with accumulated solids, by probes 12 which are movable vertically into tubes 4 and connected to a suction line (Fig. 1, not shown) which includes cyclone separator (18), filter (22) and fan (26). In Fig. 2, probes 12 are lowered by winch 38 and connected to separator (18) by a flexible pipe (16). During lining, the fibres enter the tubes by inlet 62 in an air stream, the air being extracted by fan (26) through line (63). The lower parts of the filter casing, connected to inlet and outlet and enclosing tubes 4, may be removable from the upper part, enclosing probes 12 when not in use, for convenient changing of tubes (Fig. 3, not shown). In Figs. 4, 5 (not shown) the probes (102) and a spraying chamber (104), used to apply the fibres to the tube interiors, are mounted on respective trolleys which move on tracks bridging the top of the filter casing. Probes 102 are arranged in a row and during cleaning are lowered into each row of filter tubes in turn, by pneumatic motor (124). The spraying chamber (104) is lowered against spring loading by winch (118). The filter casing is normally closed by removable covers. In an alternative probe assembly (Figs. 8, 9, not shown) the probes are moved vertically by handwheel (119) and extend through felt washers, in the bottom plate of the trolley, which wipe the probes clean as they are withdrawn. The fan (134) in Fig. 4 is used for the main filtering flow as well as for the cyclone

[Class 36] In an air-space insulated cable comprising one or more inner conductors 10, Fig. 1, spaced by members of polystyrol or other substantially non-compressible insulating material from an outer conductor or screen 16 formed of strips 16 which fit together to form a tube but which are liable to relative movement when subjected to internal pressure by the spacing members, either the spacing members are formed so as to possess a limited amount of fiexibility, or a yielding layer or skin is arranged between the spacing members and the outer conductor or screen to prevent relative displacement of the strips thereof. As shown in Fig. 1, the spacing members comprise polystyrol strings 11, 12 over which are wound polystyrol bands 13, 14 rendered flexible by rows of punched out bosses 15. The bosses may be staggered and the bosses in each row may be pressed out alternately on one and then the other face of the band. In the construction shown in Fig. 7, the spacer 35 between the inner and outer conductors 34, 38 consists of a multiply helical polystyrol cord 35 wound round the inner conductor and secured thereto by a binding 36. A reinforcing thread may run through the helical cord, the turns of the cord being bound to the thread. The individual plies of the cord 35 may be of round or sector-shape crosssection. In another construction, the inner and outer conductors are separated by ceramic discs arranged at intervals along the inner conductor, the periphery of each disc being coated with rubber. In a modified construction, similar to that of Fig. 1, the bands 13, 14 are replaced by a single unbossed band winding over which is wound in open turns a rubber thread. Specification 347,929 is referred to.

Abstract: 1,220,950. Process and apparatus for the production of speckled particulate material. UNILEVER Ltd. 19 July, 1968 [21 July, 1967], No. 34529/68. Heading C5D. A process for the production of a speckled particulate material comprising spraying at least one colourant solution over at least a proportion of the upper surface of a layer of particulate material, so that the colourant solution colours only the particles of the particulate material located at and near the upper surface of the layer leaving the other particles in the layer uncoloured, and mixing the particles so coloured with the uncoloured particles in the particulate material. A belt conveyer 20 is used to support a layer 23 of particles fed from a hopper 21 on to the conveyer through a gate 22 which is adjustable to control the width and depth of the particle layer 23 on the conveyer 20. Sprays 24 of colourant solutions are then directed on to the upper surface of the particle layer 23 as it proceeds along the conveyer. After having been sprayed, the particle layer 23 continues undisturbed along the conveyer while the coloured particles loose excess solvent until they are no longer tacky. At the end of the conveyer the particles are discharged into a continuous mechanical mixer 26. The coloured particles are dispersed thereby throughout the uncoloured particles so as to form a speckled particulate material.

[Class 94(i)] A packing machine wherein successive packing operations are carried out in working stations arranged in a circle, comprises a rotary disc 4 which is rotated continuously at a constant rate, several article carriers 12 supported by arms 11 pivotally mounted on the disc 4, and means for imparting an additional swinging movement to the arms 11 so that the carriers 12 are accelerated and decelerated with respect to the rotary disc 4 in order to obtain dwell periods for the article carriers wherein the required operations can be performed. Each arm 11 is fastened to a shaft 10 pivotally mounted on the disc 4, and the swing- ing movement is imparted to each shaft 10 by lever mechanism actuated by a roller 18 which engages a cam-groove in a stationary disc 3. The roller 18 is carried by an arm 17 rigidly connected with another arm 15 by a pin 16 extending through the disc 4, the arm 15 being connected by a link 14 to a lever 13 secured to the rod 10. In positions I, II and III, the carriers are at rest and various operations may be performed on the container or wrapper or its contents. The cam groove may be so shaped that a greater lead is imparted to the carriers than would be necessary for the desired dwell period so that the movement is gradually retarded before the carrier reaches the working station. In a modified construction the carriers are arranged to move in a vertical plane.

Title: Improvements in or relating to the surface treatment of aluminium or aluminium alloys
IPC: C25D11/24
Filed: 1931-12-17
Abstract: An adsorbent oxide coating produced chemically or electrolytically on an aluminium or aluminium alloy surface is coloured or rendered more resistant to corrosion by precipitating therein by double decomposition an insoluble inorganic compound. The oxide coating may be produced by treatment, with or without the application of electrical energy, in a solution containing any of the following substances: sulphuric acid, chromic acid, sodium carbonate, sodium sulphate, sodium bisulphate, phosphoric acid or a phosphate, ammonium citrate, or lactate, citric acid or its salts, or a mixture of potassium bichromate and sodium carbonate. The preferred solutions are sulphuric or chromic acid when anodic oxidation is employed, and a mixture of sodium carbonate and potassium bichromate when no external electrical energy is applied, details of the temperatures, concentrations and current densities employed being given.  The double decomposition reaction is carried out by immersing the oxide-coated aluminium first in a solution containing the desired anion or cation and then in a solution containing the cation or anion which will react with the anion or cation of the first solution to form the substantially insoluble inorganic compound desired.  The term "inorganic compound" is used to include ferrocyanides and ferricyanides. Various solutions which will react to give a brown, red, yellow, white, black, blue, orange, or green colouration to the oxide coating are described.  Insoluble inorganic compounds containing the chromate ion are stated to be particularly effective in increasing the resistance to corrosion.
