Title: Method and apparatus for manufacturing pellets from fusible materials
IPC: A61J3/06
Filed: 1955-06-17
Abstract: 789,685. Drop-moulding machines. BADISCHE ANILIN- & SODA-FABRIK AKT.- GES. June 17, 1955 [June 19, 1954], No. 17506/55. Class 87(2). [Also in Group XVIII] Pellets of fusible material, e.g. waxes, dyestuffs or polyethylene, are formed by allowing the material to fall as drops from a heated container 1 between the wall of a nozzle 14 and a reciprocating piston 7 onto a band 17 cooled by a water spray 19. The pistons may be reciprocated individually or collectively either by an electromagnet 10 (as shown) or by cams or pneumatically. Each piston fits loosely within its nozzle in such a manner that liquid may fall freely in a stream through the nozzle, until the piston is reciprocated which has the effect of retarding the flow on the upstroke to form drops and then to accelerate the drops on the down stroke. The lower part of each piston may be enlarged in the form of a ball or disc. The drops may be deposited on a rotating disc, the frequency of the outer pistons being made greater than that of the inner pistons to give a uniform charge on the disc. A float 4 with a rod 5 indicates the level of liquid in the container.

Title: A method of drying gaseous chlorine
IPC: C01B7/01
Filed: 1964-05-01
Abstract: 1,037,526. Drying chlorine. KONINKLIJKE NEDERLANDSCHE ZOUTINDUSTRIE N.V. May 1; 1964 [June 14, 1963], No. 18217/64. Heading B1L. Gaseous chlorine is dried by a process wherein the gas is subjected to one or more cooling steps and to two or more drying steps using sulphuric acid as the drying agent but withdrawing the acid and the gas separately from each step. The last or only cooling step is combined with the first drying step and the gas is cooled in the presence of the acid by heat exchange with an evaporating liquid. In a specific embodiment, Fig. 2, gaseous C12 which may be preliminarily cooled to not lower than 10‹C. and freed from condensed water, is supplied to Venturi tube 8. Sulphuric acid enters tube 8 by conduit 9 and the gas/acid mixture passes to heat exchanger 11. Conduit 12 introduces the gas mixture into vessel 13 below the level of the diluted H2SO4 which is cooled by coil 14 and overflows at 15. Chlorine is discharged from 13 into conduit 16 and heat exchanger 11 and passes on to vessel 18 which is fed with cone. H2SO4, oleum or liquid SO3 by conduit 20. Dry chlorine leaves at 19 while discharged acid passes along conduit 9 to tube 8. In an alternative embodiment, Fig. 3, gaseous chlorine enters at 2 while conc. H2SO4 enters at 4. Dried chlorine leaves at 3 and spent sulphuric acid leaves at 5. Acid from the lowest tray may be withdrawn and cooled to -30‹C. by cooler 22 whilst in the tray above, the acid is heated at 24 to prevent formation of a solid sulphuric acid hydrate. In another embodiment (Fig. 1, not shown) liquid C12 is fed to the tower just above the point of entry of the gaseous chlorine, thus effecting cooling of the gaseous Cl2 in the presence of the acid. An advantageous condition is that the temperature of the gaseous chlorine in the first drying step be lower than that at which chlorine hydrate will be formed but prior to or during a subsequent drying step the gas is heated to a temperature higher than that at which solid sulphuric acid hydrate will be formed.

Title: Acylation of 6-amino penicillanic acid
Inventor: PARKER GEORGE
IPC: C07D499/00
Filed: 1962-05-12
Abstract: The acylation of 6-aminopenicillanic acid to produce penicillins, is carried out by dissolving the acylating agent in an organic water-immiscible solvent in which the penicillin to be prepared is soluble at acid pH, said solvent being such as gives an aqueous phase and an organic solvent phase on admixture with water, reacting with an aqueous phase containing 6-aminopenicillanic acid or a salt thereof at a pH not greater than 5, agitating until the reaction is complete and the penicillin so produced has been extracted into the organic solvent phase.  The organic phase is separated and the penicillin recovered by conventional methods.  The pH of the reaction is 2 to 5 and especially 2 to 3.  Preferably the acylating agent is dissolved in part of the organic solvent, the remainder being mixed with the aqueous phase containing the 6-aminopenicillanic acid or salt thereof.  Excess acylating agent is used and the ratio of aqueous phase to organic phase is in the range 1 : 3 to 5 : 1 aqueous solutions resulting from a fermentation process or an enzymatic hydrolysis of penicillins may be used. In a preferred process, 6-aminopenicillanic acid is dissolved in water with the aid of alkali to pH 7, the resulting solution is mixed with an organic water-immiscible solvent especially n-butyl acetate and the mixed solutions are added to a solution of the acylating agent, e.g. an acyl chloride in further organic water-immiscible solvent, the pH is adjusted to between 2 and 3 and the penicillin is recovered from the organic solvent phase.  Specified organic solvents are ethyl acetate, amyl acetate, n-propyl acetate, chloroform, benzene and isobutylmethyl ketone.  A mixture of acetone and benzene or acetone and chloroform may also be used. The acylating agent may be a carboxylic acid halide, carboxylic acid anhydride or mixed anhydride or an ester of chlorocarbonic acid.

Abstract: 1,237,164. Synthetic polymer papers. MITSUBISHI RAYON CO. Ltd. 14 April, 1969 [27 April, 1968], No. 18883/69. Heading B5B. [Also in Divisions B6 and C3] A polymer paper, i.e. a sheet or film of paper quality with a synthetic resin base, having good opacity and good writing and printing adaptability, comprises 100 parts by weight of a thermoplastic resin, 1 to 20 parts by weight of at least one white pigment of higher refractive index than the resin and having particle sizes of 0À01 to 2 microns, and 5 to 50 parts by weight of at least one filler material of similar refractive index to the resin and having particle sizes of 1 to 40 microns, the white pigment and filler being insoluble in the molten resin and uniformly distributed therein. The thermoplastic resin is preferably isotactic polypropylene, high impact polystyrene, polyvinyl chloride or methyl methacrylate-methyl acrylate copolymer. The white pigment is an achromatic inorganic pigment, e.g. titanium oxide, zinc oxide, white lead or white bismuth, which contributes to opacity. The filler material is an achromatic inorganic pigment, e.g. clay, calcium carbonate, calcium silicate, diatomaceous earth or talc, which contributes to texture and ink-receptivity. The mixture is melted and formed into a film by conventional blown tubular extrusion or calendering methods. The quality of the polymer paper may be improved by surface treatments, e.g. corona electric discharge or immersion in an organic or inorganic solvent (to improve inkreceptivity), electron beam irradiation (to stiffen the paper), or coating with clay (to improve the appearance).
