Title: Improvements in or relating to the smelting of zinc and lead-containing materials
Inventor: MORGAN STEPHEN WILLIAM KENNETH
IPC: C22B13/00
Filed: 1953-05-13
Abstract: Metalliferous materials containing substantial amounts of lead and zinc are smelted with carbonaceous material in a blast furnace, the charge and/or the air blown into the furnace being preheated to such an extent that a reducing environment is maintained throughout the smelting charge and the proportion of carbonaceous material in the charge is not substantially greater than would be required if lead compounds were omitted from the charge.  The charge may be preheated to at least 600 DEG  C. and the air to at least 500 DEG  C.  The constituents of the charge may be separately heated, the carbonaceous material to 800-1000 DEG  C. and the remainder of the charge to 500-750 DEG  C.  A charge containing zinc enriched slag from a conventional blast furnace smelting of lead ores and lead sulphide concentrates may be treated, the lead forming, for example, 9-85 per cent of the total of lead and zinc.  A suitable quantity of carbonaceous material to be used is equal to the sum of about 90 per cent of the zinc to be volatilized and about 20 per cent of the slag to be formed.  The gaseous product resulting from the smelting operation withdrawn from above the charge level may be treated with a controlled amount of an oxygen-containing gas thereby raising the temperature of the products by oxidation of some of the carbon monoxide to permit their travel to a shock-chilling condenser without oxidation of zinc, the carbon dioxide content of the resulting gases being not over 12 per cent.  Specifications 572,961, 682,176, 682,179, 686,542, 686,585, 686,589, 726,530 and 741,243 are referred to.

Title: Improved method of packing molten cheese and the molten cheese thus packed
IPC: B65D85/76
Filed: 1937-05-14
Abstract: Pasteurized cheese is packed by pouring the hot molten emulsified cheese into a mould in which it is allowed to cool until it has set sufficiently on which the moulded piece is given a thin coating of a plastic wax-like material and then enclosed in a moist wrapper of cellulose or a cellulose derivative which shrinks on drying and fits closely to the surface of the cheese. The wax-like material used may be a solid hydrocarbon, a wax or a fat, e.g. paraffin wax, and is preferably heated to such a degree that the surface of the cheese is sterilized when it is immersed therein for coating.  Coating may also be effected by spraying or spreading.  The cellulose film used is preferably prepared from viscose, and may be coloured.  After this film has been wrapped round the cheese its ends are twisted together in such a way that the film will fit the surface of the cheese as closely as possible.  The cheese may be melted at 75 DEG  C. with addition of emulsifying agents prior to pouring into the moulds which are lined with cheese cloth.

Patent GB-711543-A (GB)
Title: An improved surface treating lacquer composition
IPC: C09D161/20
Filed: 1951-06-13
Abstract: A surface treating composition is obtained by mixing without heating a urea-formaldehyde or melamine-formaldehyde lacquer resin, a non-drying alkyd resin, cellulose nitrate, and a solvent, in such proportions that the amount of urea- or melamine-formaldehyde resin is at most 75 per cent. of the amount of alkyd resin, and the amount of cellulose nitrate is less than 10 per cent. of the solid constituents of the composition.  If desired a condensation catalyst may be included in the composition so that condensation of the aldehyde resin may take place in the applied coating at ordinary temperature, thereby producing a film-coating which is insoluble in organic solvents. Condensation may also be effected solely by heating the applied coating.  In an example, a lacquer is prepared by dissolving 8 parts by weight of cellulose nitrate, 70 parts of an alkyd resin, and 45 parts of a urea-formaldehyde resin in a solvent mixture comprising butyl acetate, ethyl acetate and toluene, to produce a lacquer containing 40 per cent. of solid constituents.  To this lacquer there is added a catalyst preparation comprising hydrochloric acid, phosphoric acid, alcohol and a solvent for cellulose nitrate.  The resulting lacquer is used within 6-10 hours. It may be applied to wood or other surfaces by brushing or spraying. The first coating may be ground down and then another coating of the same lacquer may be applied.  A smooth surface, free from pores, is obtained.  This may be ground, dulled, or polished to a high gloss. The surface produced is not affected by boiling water or hot objects, and it has high resistance to acids and alkalis.  Other condensation catalysts which may be used are benzene or toluene sulphonylchloride, phosphoric acid, oxalic acid, citric acid and zinc chloride.  To the composition there may be added softening agents, pigments, urethane resins and phenol-formaldehyde resins.  The lacquer may be applied to metal surfaces, or to paper, india-rubber or leather.
