IPC: F24H9/18
Filed: 1973-07-20
Abstract: 1432433 Burners; water heaters G SIMPSON 14 May 1974 [20 July 1973] 34747/73 Headings F4T and F4A An oil burning unit in combination with a water-jacketed boiler, adapted to burn waste oil and suitable for domestic heating or heating greenhouses, comprises a vaporizing pot 11, Fig. 3, provided with apertures 15, an annular air chamber 13 provided with an inlet 18 controlled by slidable or hingeable shutter 20, and an oil inlet 16, 17 connected to one of the apertures. In use, a small quantity of oil is ignited in the vaporizing pot 11 whereafter the unit is attached to the bottom of a boiler via peg 21 and stud 22. Oil is supplied in the form of a controlled drip-feed to receiver 17 and airflow into the chamber 13 is controlled by the shutter 20. If burnt residue builds up in the pot 11 oil will overflow from the pot through apertures 15 into the air chamber 13. The increasing oil level eventually closes the apertures 15 and thereby terminates combustion. Further rise in the oil level causes overflow via the air inlet 18. The boiler is in the form of a vertical tubular chimney (2), Fig. 2 (not shown), surrounded by an annular water jacket (4) and having a series of spaced diametrically-disposed waterways (3) open at each end into the water jacket to form heat exchangers. Water inlet (5) and outlet (6) for the jacket are connected to a heating system.
Patent GB-483862-A (GB)
Title: Improvements in or relating to processes for the treatment of beryllium ores
IPC: C22B35/00
Filed: 1936-12-18
Abstract: Beryllium is obtained by first extracting beryllium sulphate from an ore, converting the sulphate into sulphide by heating it with a carbonaceous material such as low temperature carbonization coke, and then reducing the beryllium sulphide so obtained to form the metal. Extraction of the sulphate is effected by boiling sulphuric acid of sp. gr. 1,84, the sulphate precipitating from the solution on cooling and after separation from the insoluble constituents of the ore. Orthosilicate ores of beryllium are treated directly with the acid, but metasilicate ores are first fused with alkali hydroxides, e.g. sodium or potassium hydroxides, or with alkali or alkaline earth carbonates, e.g. calcium carbonate, for conversion into the orthosilicate. The conversion of the sulphate into the sulphide may be effected at about 900-1200 DEG  C.  Carbon monoxide evolved may be utilized for heating the furnace.  Reduction of the sulphide may be effected by heating it with a metal, the heat of formation of the sulphide of which is greater than that of beryllium sulphide, e.g. aluminium or calcium, in an atmosphere of a reducing and/or inert gas and in the substantial absence of moisture, nitrogen, oxygen and oxygen-containing gases, e.g. in an atmosphere of hydrogen, hydrocarbons or argon.  Aluminium or calcium sulphide is also produced.  Reduction may also be effected by heating the beryllium sulphide in a stream of hydrogen at, say, about 1350 DEG  C. or over. The beryllium formed may be distilled, and there may be present in the condensing chamber a molten charge of a metal with which the beryllium is to be alloyed.  Specification 482,467 is referred to. Beryllium may also be obtained by subjecting the beryllium sulphide to electrolysis according to the process disclosed in Specification 482,468, [Group XXXVI].ALSO:Beryllium is produced by treating a beryllium ore to obtain beryllium sulphide which is then reduced to the metal.  Reduction may be effected by heating the sulphide with a metal, the beat of formation of the sulphide of which is greater than that of beryllium sulphide, e.g. aluminium or calcium, in an atmosphere of a reducing or inert gas or both, and in the substantial absence of moisture, nitrogen, oxygen, and oxygen-containing gases, e.g. in an atmosphere of hydrogen, hydrocarbons, or argon.  Reduction may also be effected by heating the beryllium sulphide in a stream of hydrogen at about 1350 DEG  C. or over.  The beryllium formed may be distilled, and there may be present in the condensing chamber a molten charge of a metal with which the beryllium is to be alloyed. Specification 482,467 is referred to.
