Title: Improved method for the prevention of furnace corrosion
IPC: C23F11/02
Filed: 1960-03-23
Abstract: 897,709. Preventing furnace corrosion- BRITISH PETROLEUM CO. Ltd., HYDE, J. W., and RENDLE, L. K. Feb. 27, 1961 [March 23, 1960], No. 10370/60. Class 51 (1). Corrosion is reduced in a furnace burning sulphur containing carbonaceous or hydrocarbon fuel by the injection of a nitrogencontaining shale oil base fraction into the flue gases at a point at which the temperature of the flue is below 400‹ C. The shale oil base fraction is obtained by acid washing a shale oil crude diesel oil fraction, water washing the tar extract obtained, treating- the aqueous phase with an alkali or ammonia and distilling the non-aqueous phase formed. The desired fraction is a light end cut not exceeding 40% by volume, and preferably a 15% by volume cut is used. In a furnace burning a petroleum fuel oil containing less than 5% by weight of sulphur, 0.0-0.06% by weight, based on the fuel of the shale oil fraction is injected into the furnace at a point where the flue gas temperature lies between 177‹ and 316‹ C., upstream of the metal surfaces liable to corrosion. A solution of 5% by volume of the shale oil fraction in normal hexane is injected continuously into the furnace.

Patent GB-704135-A (GB)
Title: An instrument for measuring and/or controlling the consistency of a liquid
IPC: G01N11/00
Filed: 1952-04-28
Abstract: 704,135. Electric indicating systems. STENSON, A. V. W. April 28, 1952, No. 10599/52. Class 40 (1). The resonant frequency of a cavity resonator partially filled with a liquid is a function of the liquid temperature, the consistency of the liquid and of the resonator size and shape. This relationship is used to measure the consistency of a liquid. A cavity resonator, a portion of which is occupied by a sample or flow of the liquid, is fed from a frequency stabilized oscillator and is tuned to resonance by a microscrew operated disc for some standard liquid consistency. Variations in liquid consistency then alter the cavity resonant frequency. These frequency deviations are measured electronically in known manner and used for manual or automatic adjustment of the tuning disc to restore resonance, the amount of adjustment being a measure of the deviation of liquid consistency from standard. The liquid temperature may be maintained constant by a thermoregulator and the cavity resonator kept inside a thermoregulated oven. Alternatively, both liquid and resonator temperature changes may be measured electrically and used for manual or automaticadjustment of the tuning disc to compensate for temperature changes. The temperature and consistency controls may actuate separate tuning discs, operate one disc through a differential or be applied to a differential bridge the output of which actuates a servo motor to adjust the one tuning disc. The tuning disc may move in the liquid or in a separate compartment. The cavity resonator may be made of non-absorbent insulating material with its inner or outer surface metallized and may be cylindrical, prismatic or elliptical. The liquid may pass through an insulating tube axially mounted within the resonator, the tuning disc in this case being annular and surrounding the liquid tube. Fig. 1 shows a metal or metallised insulation cavity resonator 1 having an insulating partition 3 forming a chamber 2 through which the liquid flows by way of ducts 5, the liquid chamber being lined with insulation. The cavity resonator is energised by a H.F. probe 15 and is tuned by a metal disc 8 moved axially by a microscrew 7 actuated by a servomotor 9. Deviations from resonance due to variations in liquid consistency are detected in the circuit 16 in known manner and through a servomotor 12 adjust a differential bridge 10 to actuate the servomotor 9 in the corrective sense to retune the resonator, the movement of the servomotor 12 also operating an indicator 14 or a recorder registering the liquid consistency. The liquid temperature is measured by a bulb 13, deviations from a standard temperature adjusting the bridge 10 through a servomotor 11 to actuate the servomotor 9 so as to compensate for liquid temperature variations. A further bulb,. responsive to ambient temperature changes, may be similarly connected into the bridge circuit to compensate for temperature changes of the resonator.

Title: Process for the production of foams based on maleic acid half  ester copolymers
IPC: C08J9/04
Filed: 1971-04-22
Abstract: 1352563 Foamed maleic acid half-ester copolymers BAYER AG 22 April 1971 [25 April 1970 17 Nov 1970] 10726/71 Headings C3C and C3P A foam is made by heating a copolymer of a maleic acid half ester with at least one copolymerizable monomer alone or mixed together with one or more additional polymers, expanding agents which decompose to give off gases at elevated temperatures, fire-retarding agents, fillers, e.g. an oxide, hydroxide or carbonate of an element of Groups II or III of the Mendeleev Periodic Table, dyes and volatile solvents and/or volatile non-solvents which either dissolve or swell the copolymer, at a temperature of 80-350‹ C. at which there is evolution of gas by decomposition and/or evaporation of at least one component of the composition, wherein the copolymer is converted before mixing or foaming or the composition is converted before foaming, into granules, beads or a moulding by a pressing or moulding operation. In the examples copolymers of isobutylene or styrene with the maleic half-ester, viz. a mono-methyl-isopropyl, -cyclohexyl or -ethyl maleate are prepared by copolymerizing either the respective monomers or maleic anhydride, in place of the half-ester monomer, which is then half-esterified; the copolymers if prepared in solution or mixed with solvents (e.g. methanol, isopropanol or ethanol) are then freed from sufficient solvent so as to leave 0À5- 20% by wt. of solvent and are then granulated, e.g. by discharge from the die of a degassing screw in the form of a strand which is then cut, or by pressing, and the granulates are then foamed by heating, e.g. treatment with hot air in a mould. Alternatively the dry or solvent-containing copolymers may be compounded with a blowing agent, e.g. petroleum ether, urea, methyl urea, thiourea or biuret after or before granulation and granulates may be made of the copolymer, methanol, ZnO, azodiisobutyronitrile, MgO, water, CaO, CaCO 3 , polyethyl acrylate, polyvinyl chloride, petrol, an addition product of tetrahydrophthalic acid anhydride and hexachlorocyclopentadiene, (NH 4 ) 2 HPO 4 , ethylene diamine, benzene, Al 2 O 3 , kieselguhr, MgCO 3 ; octaethylene glycol, e.g. sodium silicate, and/or antimony trioxide and the granulates are then foamed.

Title: A process of preparing crystalline materials
IPC: C30B23/02
Filed: 1969-02-28
Abstract: 1,214,272. Vapour deposition of semi-conductors. INTERNATIONAL BUSINESS MACHINES CORP. 28 Feb., 1969 [28 March, 1968], No. 10805/69. Heading C1A. [Also in Divisions C7 and H1] Crystalline materials such as the semiconductors SiC, AIN and GaAs are deposited on crystalline substrates, preferably of the same material by positioning the surface of the source first material in contact with a surface of the substrate, heating to a vaporizing temperature below the melting temperature in an inert .atmosphere, e.g. 1700‹ to 2200‹ C. with a temperature difference of, e.g. 20-50‹ C. between the source and substrate and varying the relative temperatures of the source and substrate to cause vaporized material from the source and substrate to alternately condense and grow on the substrate and source respectively. As shown in Fig. 1 the substrate 1 is positioned on the SiC source 5 in reaction chamber 3 the contacting surfaces of 1 and 5 being polished by heating in H 2  to 1700‹ C. Source 5 is heated by element 7 and substrate 1 by element 11. The inert atmosphere is argon with or without hydrogen and a patterned depsoit can be produced by preforming source 5 to the required pattern as by forming grooves 15 to define raised portions 17 which contact the substrate. Deposition then occurs only at the contacting surfaces 17. The deposit can be duped to p- or n-type either by introducing impurities such as B or N 2  into chamber 3 or by forming source 5 of a particular conductivity type material. The process can be used to provide successive growths of alternating conductivity types, e.g. PNP or NPN. Etching the substrate with hot NaOH after the deposition of the pattern removes any extraneous deposit outside the pattern. A plurality of individual diode devices can thus be built up.
