Patent GB-899900-A (GB)
Title: Process for coating particles
IPC: A61K9/28
Filed: 1960-10-27
Abstract: Solid particles are coated by suspending the particles as a fluidized bed in a gas stream of non-uniform upward velocity such that in one portion of the bed in which the gas stream moves with a relatively high velocity, the particles move upwards substantially out of contact with each other and in that part in which the gas stream moves with a relatively lower velocity, the particles move downwards in substantially weightless contact with each other, the coating materials being introduced into the gas stream at the lower end of the upwardly flowing part of the bed. For producing nonuniformity of gas velocity grids or screens of non-uniform aperture size or in which the "mesh" only covers a portion of the conduit may be placed in the gas conduit.  These may be replaced or used in combination with movable "damper" plates.  The coating compositions used may be liquids or finely-divided solids, e.g. aqueous sugar solutions and compositions comprising film-forming substances, e.g. polyvinyl alcohol, cellulose acetate phthalate and zein, natural and synthetic resins, e.g. shellac, alkyl and silicone resins, waxes and waxy materials, e.g. polyvinyl pyrrolidone, glyceryl monostearate and glyceryl monostearate, plasticizing agents, colouring agents and bulking substances, e.g. starch, talc or magnesium carbonate.ALSO:Solid particles, e.g. medicinal tablets, are coated by suspending the particles in an upwardly flowing gas stream containing coating material and causing circulation of the particles in the fluidized bed by directing the gas stream through one portion of the bed at a higher velocity than through another portion, the gas velocity being such that the particles flow upwards in the high velocity region and flow downwardly in weightless contact in the region of lower velocity, the particles p  in the upward flowing region being substantially out of contact with each other.  The coating materials are directed into the lower end of the upwardly flowing gas stream and for causing the variable gas flow velocity, there may be used grids or screens in which the size of the openings is not uniform or in which the mesh only partially covers the gas conduit in which they are placed beneath the fluidized bed and which may be replaced or used in combination with movable "damper" plates.

Patent GB-853812-A (GB)
Title: Improvements relating to the calcining of gypsum
IPC: C04B11/028
Filed: 1958-11-18
Abstract: Plaster of Paris is produced by calcining gypsum, preferably at 230-330 DEG F., substantially all the heat required for the calcination being provided by hot heat-carrying solid bodies which are continuously intermixed with fresh gypsum.  A suitable calcining kiln is shown in Fig. 2 where gypsum enters through line 12 and passes countercurrent to a stream of hot steel or ceramic balls entering through line 14 and leaving through line 22.  The plaster of Paris produced, and ground by the action of the balls, leaves through a screen 30.  The inner left-hand wall of the drum carries a plurality of spaced fingers which scoop up the balls and deposit them in the outlet pipe 22.  Employing countercurrent flow between the gypsum and the heating solids, as shown in Fig. 1, gypsum of a particle size of about 3/4 inch <PICT:0853812/III/1> <PICT:0853812/III/2> <PICT:0853812/III/3> enters the kiln 10 at 70 DEG C. and passes countercurrent to 1 1/4 inch alumina balls entering the opposite end at 330 DEG F. The plaster produced leaves through line 16 and passes through a recuperator 20 where it gives up its heat to the cooled balls which pass through lines 22 and 23 through the recuperator to a re-heater 24 where they are indirectly heated by steam from the calcining kiln.  Alternatively if a concurrent flow of gypsum and balls is employed, a flow as shown in Fig. 3 is used, wherein the gypsum enters a kiln 100 through line 112 and leaves through line 118 whilst the balls flow concurrent with the gypsum through the kiln and through a reheater 124.  The ratio of balls to gypsum is normally about 30 to 1 and the incoming ball temperatures in general are from 75-250 DEG F. above the calcining temperature. Specification 633,648 is referred to.

Title: Method and apparatus for reducing the salt and oxide content of steam generated in a high-pressure steam unit
Inventor: STAEB FRANZ PLACIDUS
IPC: F22D1/30
Filed: 1961-10-20
Abstract: 953,597. Centrifugal separators ; contacting gases with liquids. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Oct. 19, 1962 [Oct. 20, 1961], No. 37749/61. Headings B1R and B2P. The oxide and salt content of steam is reduced by bringing sufficient purified water into contact with the steam in the steam line 3 of a steam-generating unit 2 and giving the mixture a sufficient velocity so as to form a mist-annular two-phase flow pattern which is maintained in the line over a distance at least twenty times its diameter over that distance and finally separating the mixture into a centrifugal separator 10. A mist-annular flow is defined as one in which the water is partly atomized in the steam and partly flowing in an annular film along the steam line wall. The purified water is fed into the line 3 from a pump 6 via a line 5 and branch line 7. Beyond this point the line 3 narrows into a section 8 having a length equal to at least 20 times the narrowed diameter which itself is substantially two-thirds of the original diameter of line 3. By suitable choice of the amount of water supplied through line 7 and of the flow rate through section 8 the mist-annular two-phase flow pattern is obtained, most of the oxides and salts being taken up by the water. The line section 8 then changes into a wider section 9 in which the flow pattern may be changed to a plug or froth flow in which agglomeration of the small water droplets takes place. Additional purified water may be supplied at the transition between the sections 8 and 9. The line 9 opens tangentially into the separator 10 where the steam water mixture is washed through a water screen created by water flowing over the edge of a gutter 12 fed through a branch 13 from the purified water line 5. The steam then enters a cyclone 11 in which the last traces of water are removed and returned via a liquid seal 14 to the bottom of the separator 10 where they are fed back together with the wash water and separated oxides and salts to the steam-generator unit 2 via a line 15 which joins the fresh feed water line 16. The dry purified stream is removed by the line 21 and may be passed to a superheater. Dimensions of the apparatus and flow figures are given. Specifications 715,912 and 746,631 are referred to.

Title: Process for altering the ratio of fructose to glucose in invert sugar solutions
Inventor: KETT GEORGE
IPC: C13K3/00
Filed: 1959-11-10
Abstract: The ratio of glucose to fructose in invert sugar is altered by subjecting a 10 to 15% aqueous solution of invert sugar containing a nitrogen-containing nutrient to aerobic submerged fermentation at room or slightly elevated temperature by treatment with a species of Acetobacter capable of oxidising glucose to gluconic acid without attacking fructose.  It is preferred to use Acetobacter suboxydans at a working temperature of 28 DEG C. with a 12 DEG  brix invert sugar solution to which has been added Corn Steep Liquor, as a nutrient, for example in an amount of 0.5% by volume of the total sugar solution.  This mixture is injected with finely dispensed filtered air until analysis of the substrate indicates a decrease in the glucose content to the required level and a corresponding increase in the content of gluconic acid.  The process may be operated batchwise, or in an intermittent or continuous manner while intermittently or continuously removing a portion of the fermented solution and introducing an equivalent amount of the invert sugar solution containing the nutrient.ALSO:A soft drink contains an aqueous solution made by subjecting a 10 to 15% aqueous solution of an invert sugar containing a nitrogencontaining nutrient to aerobic submerged fermentation at room or slightly elevated temperature by treatment with a species of Acetobacter capable of oxidizing glucose to gluconic acid without attacking fructose.  It is preferred to use Acetobacter suboxydans at a working temperature of 28 DEG  C. with a 12 DEG  brix invert sugar solution to which has been added corn steep liquor, for example in amount of 0.5% by volume of the total sugar solution.  The mixture is injected with finely dispersed filtered air and the fermentation is stopped when the solution contains 16 to 20% by weight of fructrose, 10.5 to 13.5% of glucose and 2.7 to 3.9% by weight of gluconic acid.  The fructose enriched solution may be treated with active carbon to remove undesired colour and flavour and the Acetobacter removed by passing the solution through a biological filter for example sterimats.  Salts such as sodium gluconate and excess acids can be removed by passing the solution through ion exchange resins.  The purified mixture may, if desired after concentration, be blended with flavours or fruit or vegetable juices, coloured and aerated and pasteurized before bottling.

Abstract: 1,165,012. Isocyanates; aminimides. UNIVERSITY OF IOWA. 25 Aug., 1966 [26 Aug., 1965], No. 38244/66. Heading C2C. Organic isocyanates are prepared by pyrolysing an organic aminimide. In particular an isocyanate of formula R(N = C = O) n  in which R is an aliphatic, cycloaliphatic or aromatic group of valency n is prepared by pyrolysing an aminimide of formula in which R 1  R 2  and R 3  are alkyl or aryl groups or R 2  and R 3  may be joined to form a heterocyclic ring and n is an integer. The aminimides used as starting materials may be prepared by first forming an acyl hydrazine by reacting an acid anhydride or acid chloride with an unsymmetrical hydrazine and converting the acyl hydrazine to an aminimide by either reacting it with an alkyl halide in the presence of an alkali metal hydroxide or by reacting the acyl hydrazine with an alkyl halide or an ester of a strong organic acid such as a sulphonic acid to yield the hydrazonium salt and treating this with a base. Examples are given of the preparation of (a) phenyl isocyanate by reacting benzoyl chloride with unsymmetrical dimethyl hydrazine to give 1,1-dimethyl-2-benzoylhydrazine, forming a hydrazonium salt by treating the benzoyl hydrazine with methyl-p-toluene sulphonate; treating the salt with sodium hydroxide to given trimethylamine benzimide and pyrolysing this to give phenyl isocyanate; and (b) methyl isocyanate by reacting acetic anhydride with 1 - amino - 2 - phenylpyrrolidine to give 1-acetamino-2-phenyl-pyrrolidine: treating this with methyl iodide to give the hydrazonium salt; treating the hydrazonium salt with sodium hydroxide to give 1-methyl-2-phenylpyrrolidine acetimide and heating this to give methyl isocycanate. A list of suitable starting aminimides is given which would produce mono-, di- and tetra-isocyanates.

Title: Lifting apparatus for stacks of bales and the like
Inventor: SCOTT DONALD ALAN
IPC: A01D87/12
Filed: 1961-10-27
Abstract: 952,659. Tractor attachments for gripping bales. NU-WAY HEATING PLANTS Ltd. Oct. 2, 1962 [Oct. 27, 1961], No. 38488/61. Heading B8H. A tractor attachment for lifting stacks of bales has arms 9, Fig. 1, which are moved into engagement with opposite sides of the stack by extension of a ram 15, further extension of the ram causes the arms to be tipped towards the tractor so that the bales rest against a vertical support 17, Fig. 2. A frame 1 of the device is connected to conventional power lifting arms 3 of a tractor and a member 4, pivoted to the frame 1, is attached to the tractor by a link 5 so that as the arms 3 are raised the member 4 remains vertical. The arms 9, Fig. 1, are held apart by springs 12. Initial movement of the ram 15 does not stretch the springs 12 until the arms 9 abut the bales. When this occurs further extension of the ram rotates levers 11 against the force of springs 12 thereby exerting a pull on links 13. This pull rotates a shaft 8, Fig. 2, mounted in the frame 1 and with it a lever 7 which is attached to a rod 6. Since the rod 6 is fixed to the top of the member 4 rotation of the shaft 8 raises the front of the frame 1 and with it the arms 9, thus tilting the bales backwards to a position in which they rest against the support 17.
