Patent GB-719313-A (GB)
Title: Synthesis of strains of micro-organisms
Inventor: PONTECORVO GUIDO PELLEGRINO AR
IPC: C12N15/04
Filed: 1951-10-24
Abstract: A process for the manufacture of new strains of micro organisms, which comprises the selection of two strains of a micro organism whose genetical factors it is desired to combine, and having genetical markers which enable the strains to be easily distinguished and complementary nutritional requirements or sensitivity to poisons inoculating the strains in a medium deficient in the complementary nutrients or containing the complementary poisons of the strains as the case may be, growing the heterokaryon so formed, or its conidia, in the same or a similar medium, thereby favouring multiplication of heterozygous nuclei in which factors of the marker strains are combined, recognizing the cells carrying the heterozygous nuclei by means of the markers and establishing a strain thereof, and selecting from the latter strain a stable recombinant strain which is produced from the heterzygous strain and combines in a desired manner the different genetical factors of the originally selected strains. Strains having suitable genetical markers, e.g. nutritional requirements, growth habits or colour, are obtained naturally or by artificial means, e.g. irradiation of natural strains.  The formation of heterozygous nuclei is accelerated by treating the heterokaryon in the cultivation stage with a polypoidogenic agent such as camphor, acenaphthene or borneyl chloride.  Where a desired mitotic recombinant is less easily recognized than a sister recombinant, such a desired recombinant is selected by removing from the heterozygous culture a part thereof adjacent to said sister recombinant.  Examples describe the production of new strains of Aspergillus nidulans, Aspergillus niger and Penicillium chrysogenum.
Patent GB-670501-A (GB)
Title: Improvements in or relating to the manufacture of melamine
Filed: 1948-09-23
Abstract: Melamine is made by reacting a cyanuric halide with 100-500 per cent of its weight of anhydrous ammonia above 100 DEG  C. at a pressure greater than 500 p.s.i.  Alternatively, the cyanuric halide may be reacted at atmospheric temperature to give a monohalo-diamino-triazine, and the reaction completed with more ammonia above 100 DEG  C.  The halide may be chloride, bromide or a mixture of the two.  An organic solvent such as ether may be used if desired.  The excess ammonia may be recovered and recycled, the ammonium halide removed by filtration and washing with water leaving melamine.  Examples are given of the process. Specification 502,148 is referred to.ALSO:Cyanuric bromide is obtained by the bromination of hydrocyanic acid or sodium cyanide to give cyanogen bromide which is then polymerised at a low temperature with aluminium bromide.  Use of aluminium chloride yields a product containing some cyanuric chloride.  Specification 502,148, [Group IV (b)], is referred to.

Patent GB-277987-A (GB)
Title: Improvements in the production and activation of carbon
IPC: C01B32/336
Filed: 1927-09-22
Abstract: 277,987. Daniels, J. S., (Assignee of Meeze, E. H.). Sept. 22, 1926, [Convention date]. Carbon.-Active carbon is produced from wood, peat, lignite, brown coal and other carbonaceous materials, alone or mixed, by destructively distilling at reduced pressure in the presence of steam or inert gases, or both, or of oxidizing and other active gases. The carbon is next cooled under conditions favourable to the occlusion of atmospheric oxygen, and may then be ground and treated with catalytic materials, and is finally subjected to a second heat treatment in which the occluded oxygen increases the activation of the carbon. The raw material is first heated under reduced pressure to 500-800 ‹C. in a retort preferably of metal, the volatile products, which may be withdrawn by the aid of a pump, being passed through a condenser. Steam, preferably superheated, is supplied to the retort. The pressure within the retort may be varied periodically through a large range. When the volatile products have been removed, pressure is returned to normal by reducing the exhaustion and continuing the injection of steam with or without the addition of combustion gases from without the retort. The carbon is allowed to cool in a water sealed vessel and is then crushed in a roller ball or tube mill, catalytic material in relatively small amount being added therein either in powdered form or as a solution atomized by steam &c. Compounds of zinc, magnesium, ammonium, cadmium, and tin are used as the catalysts, e.g. zinc and cadmium chlorides and zinc oxide mixed with ammonium chloride. The carbon may be graded at this stage. The final heating may take place in a fireclay retort, preferably horizontal or inclined, the temperature. employed being up to 1000‹ C., for example 850‹-1000‹ C. The finished carbon does not generally require treatment to purify it from the catalytic material, which may also be added at other stages, e.g. before the first heating. The active carbon may be obtained in granular or block form by starting with suitably porous raw material in granular or block form impregnated with catalyst. The heat treatments may take place in a single or in separate retorts, and may be operated continuously or discontinuously.

Title: Improvements in or relating to machines for automatically making wire fabrics
IPC: B21F31/00
Filed: 1923-10-18
Abstract: 205,817. Bek, E. G. Oct. 18, 1923. Making metal fabrics.-In a machine for making ringmesh, two or more wires of different cross-saction, material, or colour are selectively placed in position to be fed to the benders by guides electrically-operated through a pattern the surface of which is part of electrically conducting material and in part of non-conducting material. The completed mesh is carried by pins on an intermittently-rotated roll b<3> mounted in a frame b<2> which is pivoted on a shaft n carried by an intermittently-operated slide b. The roll may be mounted directly on the shaft n. The shaft is feathered to receive an axially fixed drum h, to which is attached a weighted cord h<1> passing over guides, and secured to a wheeled carriage f<1> for the pattern plate f. The shaft n is rotated by a chain n<1> from the shaft of the roll b<3>, and the shaft n or slide b is connected' at one end to a weighted cord c, which is connected also to a slide d provided with a spring-pressed contact pin d<2> for engaging the pattern. The pattern which is in part covered with a non-conducting material, preferably lacquer, is traversed by the shaft n on the completion of each row of links and the contact pin is traversed by the slide b after each link is formed. The contact pin may be made movable in both directions and the pattern stationary. When the contact pin engages a conducting portion of the pattern an electromagnet K is energized so as to attract the pivoted armature m and thus bring one of the wires m<1>, m<2> pivoted therein into feeding position. The armature is returned by a spring K<3> so as to bring the other wire into position when the contact pin engages the non-conducting part of the pattern. The Specification, as open to inspection under Sect. 91 (3) (a) states that when using more than two wires a pattern may be provided also on the under surface of the plate f, and the strength of current may be varied by using a metal of different conductivity for the pattern plate. This subject-matter does not appear in the Specification as accepted.
