Title: Treatment of clay
Inventor: GOSKAR TYRREL ADRIAN
IPC: C04B33/04
Filed: 1960-09-26
Abstract: Clays, particularly china-clays are bleached by treating in an acid slurry with aqueous bisulphites in the presence of granulated metal on a stationary bed producing hydrogen by reaction with acid.  The metal used has a particle size such that 90% is held back on a 10 mesh screen (British Standard sieve) and is preferably zinc or magnesium.  An electro-couple may be formed between the above metals and copper or aluminium, which metals improve reduction of ferric iron.  Acidity of the slurry/bisulphite mix is maintained by addition of mineral acids and pH is adjusted to about 4 after bleaching by adding calcium carbonate.  Sequestering agents such as orthophosphate (see Specification 520,498) are used before filtering off the product. According to the example, china clay was slurried in water with sodium bisulphite and pH adjusted to 2.5 with sulphuric acid, mixed in a pump and passed up and down a cylindrical tower containing a layer of granulated zinc.  The pH was adjusted to 4 and the slurry was treated with sodium silicate prior to filtering and drying. The bisulphites used are those of cations which do not contaminate or discolour the bleached clay product and are preferably those of alkali metals.  The metals used in the stationary bed also must not produce cations which contaminate the clay product.

Abstract: 1,222,253. Forming flat bottom packages. MIRA-PAK Inc. 15 July, 1968 [19 Dec., 1967], No. 33552/68. Heading B8C. A continuous web 11 of packaging film is formed into a tube 18, transversely sealed at spaced intervals and then severed to form gussetted or " pillow " packages, by means of a former 16 and longitudinal sealing means 17 which are reciprocated vertically and by means of sealing and severing jaws 22a and 22b which are reciprocated horizontally as described in Specification 918,469, but each package is formed with a flat bottom so that it will stand. As the former 16 is moved upwardly (while the jaws 22a and 22b clamp the cut lower end of package B) to form a further length of tubular material (for package C), piston-and-cylinder 47 is operated to move a cam 42 downwards thereby rotating a pivoted plate 44 to a horizontal position within the tube 18, the lower end of the package B flattening itself against the plate 44. Adhesive is supplied by a nozzle (50), Fig. 4, not shown, to the outside of the lower end of the package B, and a platen 30 is then pressed against the end by a piston-andcylinder 34. The platen 30 and plate 44 swing back into vertical positions as the former 16 moves downwards so that product may be introduced through the upper end of the former 16 and the tube 18. After sealing of the top end of package B, it is stripped away as described in Specification 943,574. If " pillow " type packages are formed, the two ends of the lower seal may be secured against the sides, or the bottom, of the package. The longitudinal seal may be at one side instead at back or front of the package.

Title: Method and apparatus for determining the difficulty of removing pollutants from gas
IPC: B04C5/26
Filed: 1970-07-10
Abstract: 1317633 Test-scrubbing gas streams NATIONAL DUST COLLECTOR CORP 10 July 1970 [28 Aug 1969] 33701/70 Heading B1R [Also in Division G1] The optimum conditions for scrubbing dust from gas streams are determined from gas samples removed from 20 predetermined points in gas conduit 10 by probe 12. The sample is passed by line 14 to portable unit 20, entering-dry cyclone separator 64 through connector 16. Most of the large particles collect in receptacle 66, but gas containing fines leaves by line 68 and passes to flooded disc orifice assembly 72, which is also fed with wash water from reservoir 94 by means of pump 96 and line 88. The pressure drop across assembly 72, as measured by meter 98, is adjusted by means of valve 92 or by changing the orifice plate (84) (see Fig. 3, not shown) in assembly 72. The thoroughly wetted gas stream passes by line 100 to wet cyclone separator 102, separated water and dust being collected in receptacle 1.04. The partially cleaned stream then passes through two more similar stages operated at successively higher gas velocities and pressure drops across orifice plate assemblies 172, 272. The gas leaving unit 20 is passed through a total filter 30, condenser 36, thermometer 38, flow-regulator 42, and meter 44 to exhaust through pump 50. If required all but one wetwashing stage of unit 20 may be bypassed by means of line 310. By first bypassing unit 20 entirely and collecting all the dust on total filter 30, the proportion of dust separated in each stage under the conditions therein prevailing may be calculated, thereby enabling optimum conditions to be built into on-stream scrubbers. An adaptation of the apparatus which is suitable for pilot plant operation is also described (see Fig. 4, not shown).

Patent GB-950055-A (GB)
Title: Improvements in or relating to color television recording and reproducing systems
IPC: C08F291/00
Filed: 1962-09-04
Abstract: Linear block copolymers are produced by swelling a cross-linked polymer by contacting it with the vapour of a polymerizable olefinic compound at a temperature sufficient to rupture weak bonds present in the cross-linked polymer, whereby a block copolymer is formed.  The degree of cross-linking in the initial polymer must be such as to permit its swelling by the olefinic compound without forming a solution of monomer in polymer.  The cross-linked polymer may be derived from acrylic and methacrylic acids and salts, esters, amides and nitriles thereof, vinyl esters, aromatic and aliphatic olefines, unsaturated ketones and ethers, vinyl substituted heterocyclic compounds, vinyl and vinylidene chlorides, tetrafluoroethylene, acrolein, itaconic acid, maleic anhydride, coumarone and indene, or may be a condensation or natural polymer, e.g. condensation products of formaldehyde with phenol, urea or melamine, alkyd resins, nylons, silicones, rubber, shellac, ester gum cellulose esters or protein. The required degree of cross-linking may be introduced into the polymer by the use of polyunsaturated comonomers, by the use of cross-linking agents subsequent to polymerization, by mechanical treatment in the presence of cross-linking agents, as described in Specification 945,717, by means of high energy irradiation, or by the bulk polymerization of monomers, e.g. methyl methacrylate, which gives rise to lightly cross-linked products.  The chain length of the block copolymerized monomeric material may be controlled by diluting the vapour of the monomer with an organic vapour which may be a solvent or a non-solvent for the base polymer.  In the examples the vapours of styrene, acrylonitrile, vinylidene chloride, vinyl acetate, ethyl acrylate, divinyl benzene, methyl methacrylate, vinyl ethyl ether, vinyl 2-methoxyethyl ether and alpha-methyl styrene are block copolymerized on to bulk polymerized polymethyl methacrylate, and the vapours of acrylonitrile, styrene and vinylidene chloride are block copolymerized on to a copolymer of methyl methacrylate with a small proportion of ethylene dimethacrylate.
