Abstract: 1,262,787. Semi-conductor devices. SIEMENS A.G. 2 May, 1969 [6 May, 1968], No. 22462/69. Heading H1K. One or more semi-conductor devices are mounted on a substrate which has isolated conductive connections extending between its upper and lower surfaces, at least two electrodes of the or each device being connected to these connections at the mounting surface so that contact may be made at the free face of the substrate. One form of substrate is produced by cutting a slice from a clamped bundle of surfaceoxidized tantalum wires. In another form the mounting surface of the substrate is the edge face of a sequence of alternate semi-conductive (conductive) and insulative materials. In a further form a semi-conductor substrate of one conductivity type is provided with highly conductive diffused channels of the opposite conductivity type. With the first and second forms a preformed semi-conductor body may be secured to the substrate by depositing over the two held in contact a film of silicon oxide or silicon nitride. Instead a semi-conductor body may be formed by epitaxial growth on the substrate-if the tantalum wires are correctly orientated and closely spaced a monocrystalline silicon layer may be grown on the substrate slice; if the semi-conductor-insulator alternate sequence consists of silicon and intrinsic silicon carbide epitaxially grown on one another, monocrystalline silicon may be grown on this (successive silicon layers may be alternately of P- and N-type). In the remaining form the substrate may consist of an anisotropic material such as graphite or certain (unspecified) organic materials. The embodiments described are (a) a mesa transistor with its emitter and base electrodes connected by metal tracks to appropriate areas of the mounting surface of the siliconsilicon carbide substrate, and (b) two transistors and a diode interconnected and mounted on a diffused-connection semi-conductor substrate.

Title: Process for providing cement articles with superficial colouring
IPC: C04B41/52
Filed: 1937-08-16
Abstract: Freshly prepared cement or asbestos-cement plates, tiles &c are coloured by the deposition of coloured heavy metal oxides or hydroxides in their superficial portions by treating them first with a solution of a salt of the heavy metal, and then with an alkaline agent in conjunction with an oxidizing agent.  The heavy metal salt, e.g. a chloride or nitrate may be used in aqueous solution of pH value 3-7, or dissolved in an organic liquid such as alcohol or acetone.  Solutions of iron salts such as ferric chloride may be reduced prior to use by the addition of iron scrap.  The after-treatment may be with sodium carbonate or caustic soda lye in conjunction with hydrogen peroxide, or an alkaline agent having also oxidizing properties such as bleaching powder solution or alkaline-reacting solutions of permanganate or chromates.  Treatment with permanganate may follow treatment with ferrous salt, copper salt, or manganate solutions, and treatment with chromates may follow copper salts.  The reaction may leave also a hygroscopic salt in the outer layer, e.g. treatment with manganese chloride followed by bleaching powder solution deposits manganese oxide and calcium chloride.  Immersion in an aqueous solution of manganese chloride and ferric chloride containing iron scrap, may be followed by treatment with bleaching powder solution.  The Specification as open to inspection under Sect. 91 describes also the colouring of asbestos-cement plates by coating with an alcoholic solution of ferric chloride, drying, and dipping in aqueous sodium carbonate. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the production of basic aluminium sulphate
IPC: C01F7/74
Filed: 1934-08-01
Abstract: Basic aluminium sulphate having the formula 3Al2O3.2SO3.9H2O is obtained by partially neutralizing the normal salt with calcium oxide or equivalent calcium compounds, about 7 mols. of CaO being used for the treatment of 3 mols. of Al2(SO4)3, extracting the mixture with sulphurous acid, and precipitating the basic sulphate from the extract by boiling to remove the sulphurous acid as sulphur dioxide, which may be collected for re-use.  The neutralizing and extraction steps may be combined by using calcium bisulphite, or a mixture thereof with lime, or calcium sulphite in the process.  A more basic sulphate may be obtained by adding an alkali such as sodium carbonate either to the sulphurous acid extract or to the basic sulphate separated therefrom, the sodium sulphate formed being removed by washing in the latter case.
Patent GB-583670-A (GB)
Title: Coating compositions
IPC: C09D5/08
Filed: 1944-11-15
Abstract: Primer coatings, especially for structural iron and steel forms, comprise a polyhydric alcohol mixed ester of a b -furylacrylic acid and a monofunctional monocarboxylic acid of different structure, red lead, drier and solvent.  The manufacture of the mixed ester is described in Specification 569,404, [Group IV].  In the examples, the compositions include b -(2-furyl) acrylic-soya acids glyceride or b -(2 furyl) acryliclinseed acids glyceride; a blend of lead and manganese naphthenates; red lead, with or without iron oxide pigment; and a hydrocarbon solvent. Raw linseed oil or soya oil may be added. The compositions can be prepared by dispersing the pigments in part or all of the glyceride on a three roll mill, the remaining glyceride being then added with the drier and sufficient diluent to produce the desired viscosity.  The compositions may be applied by brushing or spraying and are of particular value for partially rusted or scale clad structural steel forms and plates.  The desired proportion of a b -furylacrylic glyceride may be obtained by using the calculated amount of a b -furylacrylic acid or esterifiable derivative. Alternatively a mixed ester of a b -furylacrylic glyceride content higher than that desired may be prepared and blended with the drying oil whose acids are being used to give a mixed ester of the desired b -furylacrylic glyceride, by heating the two oils with stirring in an oxygen-free inert gas atmosphere.

Abstract: 978,019. Gas chromatography. COMMUNAUTE EUROPEENNE DE L'ENERGIE ATOMIQUE. June 13, 1962 [June 15, 1961], No. 22722/62. Heading B1L. In a method for the analysis by gas chromatography of a liquid mixture, which may contain components with widely different boiling points, using a stream of carrier gas and a column packed with solid particles coated with a solvent, maintained at constant temperature, the rate of flow of the stream of carrier gas through the column is increased at least once during the analysis whereby sharp, distinctly-spaced peaks on the chromatogram are obtained for the individual components of the mixture. The rate of flow of carrier gas is preferably increased at points in time predetermined from a preliminary chromatogram of the mixture, obtained using a column operated with a constant rate of flow of carrier gas. Carrier gas from source 1 flows into pressureregulator 2, and the gas then passes on to column 6 via three-way valve 3 and either or both of two different flowpaths 4 and 5 of different flow-resistance. These flowpaths are each provided with flow control means, e.g. capillary tubing, an orifice, a diaphragm, or porous filling. In operation, valve 3 is first positioned so that the carrier gas flows to the column 6 via the flowpath of higher resistance At the desired time, as determined by a preliminary test, valve 3 is operated to switch the gas flow to the flowpath of lower resistance whereby the rate of flow of gas in the column is increased. An example relates to the analysis of a mixture of ortho-, meta-, and paraterphenyl, triphenyl, ortho-meta-quaterphenyl, and 1,2,4-triphenylbenzene, dissolved in benzene, using hydrogen as carrier gas and a column packed with diatomaceous earth impregnated with a silicone grease. The analysis of a mixture of hexane, benzene, tetraline and alpha-tetralone is also exemplified.
