Title: Improvements in or relating to burners for gaseous or vaporous fuel
IPC: F23D3/00
Filed: 1934-11-09
Abstract: 430,877. Gas and vapour burners. SVENSKA AKTIEBOLAGET GASACCUMULATOR, Lidingo, near Stockholm. Nov. 9, 1934, No. 32328. Convention date, July 20. [Class 75 (i)] [See also Group XIII] In a burner in which fuel is supplied on one side, and air on the other side, of one or more perforated partitions so that the air passes through the perforations into the fuel to effect combustion, the total area of the perforations turned towards air is less than the total area turned towards fuel. In the combustion-tube burner shown applied in a water heater, oil, supplied by a regulator 2 according to the heat required, falls in drops into a funnel 4 and runs down a pipe 5 into a vaporizing chamber 9, the vapour passing through a channel 12 and up between the perforated tubes 16, 17 where it is burned with air entering through inlets 19 and passing through the chambers 16<a>, 17a and the perforations into the fuel. The combustion products pass through a chamber 20, containing water ducts 22, to a flue 21. Each tube 16, 17 consists of two perforated walls 23, 24 and 25, 26 and the spaces between the walls are divided into sections 29, 30 by means of ring-shaped bulges 27, 28 in one or both walls. The total area of the perforations in the walls 23, 26 of each section is such as to pass the required amount of air for combustion within the section, while the greater total area of the perforations in the walls 24, 25 of the section is such as to reduce the velocity of the air to the required rate. The relation between the total area of perforations in the walls 24, 25 and that of the perforations in the walls 23, 26 in a section may decrease towards the top of the burner to increase the velocity of the air for obtaining a constant combustion temperature or the total area of perforations per unit of area in the walls 23, 26 may be decreased as at the centre of the burner for distributing the combustion. When crude oil is employed, the velocity of the air is preferably 30 cms. per sec. increasing up to about 50 cms. per sec. towards the top of the burner. Each section may be provided with a single perforation in each wall or, instead of double-walled tubes, thicker tubes with conical or funnel-shaped holes may be used.

Patent GB-464752-A (GB)
Title: Improved process for the alkylation of aromatic compounds
IPC: C07C2/70
Filed: 1935-10-17
Abstract: Aromatic compounds are alkylated by reaction with olefines, or compounds such as ethers or alcohols yielding olefines on dehydration, in the presence of a solid catalyst in the form of graded or shaped particles prepared prior to the alkylation by calcining a mixture of a phosphoric acid and a finely-divided solid adsorbent.  Benzene and propylene yield isopropyl benzene. Aromatic phenols or amines can also be used.  The preferred catalysts are prepared by calcining a mixture of the ortho- or pyro-acid and the adsorbent under controlled temperature conditions to produce an acid usually between the pyro- and meta-acids in composition.  The preparation of these catalysts is described, for example, in Specification 463,272, [Group III]. Steam or aqueous fluid may be added to the olefinic gases as described in Specification 464,672 to prevent dehydration of the catalyst.  Benzol vapour and gaseous olefines, e.g. gases from the stabilizer of a cracking plant, are passed at 260 DEG  C. and 3,4--5 atmos. through a tower charged with sized particles of catalyst. Substantially all the propylene and butylenes react yielding mainly mono-alkyl benzols of motor fuel boiling range and high blending octane number.  Alkylated phenols made by the process are added to gasolines for stabilizing against resin formation and deterioration.  Specifications 457,997, [Group III], and 464,753, also are referred to.ALSO:Aromatic compounds are alkylated by reaction with olefines, or compounds such as ethers or alcohols yielding olefines or dehydration, in the presence of a solid catalyst in the form of graded or shaped particles prepared prior to the alkylation by calcining a mixture of a phosphoric acid and a finely-divided solid adsorbent.

Abstract: 869,832. Handling nuclear fuel elements. BABCOCK & WILCOX Ltd. Jan. 13, 1960 [Oct. 13, 1958], No. 32564/58. Class 39(4). A fuel element charging machine 3 displaceable above the reactor cap 1 to permit the opening 13 to be sealed to a selected charge tube includes a magazine 10 having two concentric series of fuel element chambers 17. The magazine is mounted for rotational movement about a shaft 18 within a housing 9 to permit the, chambers 17 of either series to be brought successively into alignment with holes 11 which lie on the path of a grab hoist 12. The particular series of chambers 17 which is in alignment with the holes 11 is determined by lateral displacement of the shaft 18 within upper and lower slide bearings 19, 20, movement of the shaft being effected by hydraulic cylinders 26, 27. The magazine is rotated by a motor 31 driving a telescopic splined shafting 32, 33, a pinion 34 on the shaft 33 co-operating with an annular ring gear 35 on the magazine. Spent fuel elements removed into the magazine may be cooled by coolant gas withdrawn from the reactor and circulated through a heat exchanger 6 by a fan 7, the gas passing through openings 8 in the housing 9, and being caused to pass through the chambers 17 by a bellows seal 37 fixed to the magazine and having a rotatable sliding connection 38 with the roof of the housing. In a modified arrangement (Figs. 4-6, not shown), the lateral movement of the shaft 18 is effected by a sun and planet gearing driven by an electric motor and this movement may be prevented by an electromagnetic clutch.
