Title: Improvements in and relating to weather-proof paints
IPC: C09D5/08
Filed: 1928-03-13
Abstract: 288,601. Deutsche Gasgluhlicht - Auer-Ges. April 13, 1927, [Convention date]. Paints.-Oil paints are rendered weather-proof by adding small quantites of fungicide substances. Suitable substances are compositions of copper, zinc, cadium and mercury compounds. When paint containing zinc oxide or lithopone is employed, complex copper compounds, which will riot react with the pigment to form coloured bodies, must be used. According to one example 0.3 per cent of a complex phenol copper compound is added to a. white titanium paint ; alternatively, a complex cresol copper compound may be added, In another example the fungicide substance added to a white lead paint consists of 0.3 per cent of a complex copper compound of m toluidin. Instead of the touidin other aromatic amines in combination with copper may be selected. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification wherein paints having a grey or brown tint are weather-proofed by selecting as a pigment ores which have a copper content, such as iron ores of titanium containing copper. This subjectmatter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 2667/97 and 5373/98.

Title: Improvements in or relating to magnetic recording media
IPC: G11B5/633
Filed: 1950-03-29
Abstract: A magnetic recording medium in sheet or tape form comprises a thin flexible backing and a firmly attached coating of a uniform dispersion of about two parts of ferromagnetic particles in one part of a binder comprising a flexible and abrasion-resistant blend of a rubbery butadiene-acrylonitrile polymer soluble in methyl isobutyl ketone and a high molecular weight vinyl polymer other than a butadieneacrylonitrile polymer which is also soluble in methyl isobutyl ketone, the Taber abrasion resistance value of the product being at least 300 revolutions per mil.  The method of determining the abrasion resistance value is described.  In examples (1) a cellulose acetate film is prime-coated with a solution in methyl isobutyl ketone of a blend of rubbery butadieneacrylonitrile copolymer and a compatible spiritsoluble heat reactive phenol-aldehyde resin, a partially reacted condensation product of one mol. of phenol, 0.25 mol. of acetaldehyde and 0.95 mol. of formaldehyde being suitable; it is then coated with a solution in methyl-isobutyl ketone of four parts of a copolymer of 90 parts of vinyl chloride and 10 parts of vinyl acetate, a small amount of an organic lead stabilizer such as lead stearate or phthalate and one part of a rubbery copolymer of 65 parts of butadiene-1,3 and 35 parts of acrylonitrile, to which two parts of a magnetic red iron oxide powder in which the particles are of a "chunky" character, is added, the solvent being volatilized and the tape passed twice through a supercalender; (2) two parts of acicular magnetic iron oxide powder dispersed in one part of a 60 : 40 blend of the vinyl copolymer and rubbery polymer used in the preceding example, is used for coating a similarly pre-coated backing; (3) thin rope-fibre tissue paper is saturated with a solution in methyl isobutyl ketone of a 90 : 10 vinyl chloride - vinyl acetate copolymer, dioctyl phthalate and a stabilizer, to which titanium dioxide pigment is added; it is then coated with the dispersion used in the preceding examples and supercalendered.  The copolymers of vinyl chloride and vinyl acetate used have a vinyl chloride content of from about 86 to 91 per cent, the remainder being vinyl acetate or a mixture thereof with vinyl alcohol or some other copolymerizable monomer, are soluble in methyl isobutyl ketone, and have a molecular weight of 10,000 or more. Suitable butadiene-acrylonitrile polymers, soluble in methyl isobutyl isobutyl ketone, have from about 75 to about 55 of butadiene to about 25 to 45 parts of acrylonitrile.  The coating composition may contain stabilizers, antioxidants or preservatives and wetting or dispersing agents.  Solvents or solvents mixtures other than methyl isobutyl ketone may be used, e.g. a mixture of the latter with toluene.

Title: Improvements in nuclear reactors and a method of operating same
IPC: G21C7/26
Filed: 1964-02-28
Abstract: 1,061,274. Controlling reactors. BABCOCK & WILCOX CO. Feb. 28, 1964 [Feb. 28, 1963], No. 8560/64. Heading G6C. In a fast-fission breeder reactor, spectralshift reactivity control is provided by the neutron moderating effect of the coolant. Emergency shut-down is carried out by raising the neutron leakage rate from the core by releasing coolant moderator therefrom. The coolant is either superheated steam, or water above the thermodynamic critical pressure and is a mixture of H 2 O and D 2 O. Control in accordance with short term load conditions occurs as the core temperature, and hence the coolant density, alters so as to adjust neutron leakage. Control of the ratio of H to D also maintains core criticality during alteration of the fission product core poison content. Owing to the decrease in coolant density with core temperature, zones of high temperature within the core are caused to have a reduced reactivity, thereby lowering the zone temperature to the average level. The fuel, fissile to fast neutrons is U235, Pu239 or U233 and the fertile material U238 or Th232.
