Title: Process for converting oxygen containing organic substances, such as phenols, into substances free from oxygen
IPC: C10G3/00
Filed: 1929-02-08
Abstract: 331,199. Elkington, H. D., (Naamlooze Vennootschap de e. Bataafsche Petroleum Maatschappij). Feb. 8, 1929. Cyclic hydrocarbons. - Cyclic organic oxygen compounds such as phenols, cresols, furfurol, and cyclohexanol are converted into the corresponding cyclic hydrocarbons by heating under pressure with hydrogen, or a gas mixture containing hydrogen or yielding hydrogen under the conditions of the reaction, for example mixtures of carbon monoxide and steam, in the presence of a catalyst comprising finely divided absorption carbon or coal, such as finely divided brown coal or the like, intimately mixed with finely divided molybdenum, or molybdenum compounds. The oxygen containing compounds may be mixed with carbonaceous material, or carbonaceous materials such as tars which contain phenols, cresols and the like. may be used. When such carbonaceous substances are used, they are for the most part liquefied by destructive hydrogenation, and the oxygen containing compounds are simultaneously converted into the corresponding cyclic hydrocarbons. A suitable catalyst is prepared by reducing an acid solution of ammonium molybdate with hydrogen sulphide, and absorbing the blue-coloured colloidal solution so obtained by means of absorbent carbon. The catalyst may be recovered at the end of the reaction and used again. Examples are given, using a catalyst of the above described nature, of (1) the reduction of crude cresols at 450‹ C. to a crude toluene; (2) the reduction of crude cresols to a crude toluene by heating to 450‹ C. under pressure; (3) the reduction of an oil containing 23 per cent of cresols; (4) a combined reduction and destructive hydrogenation of a mixture of raw cresols and Carisborg brown coal, by heating to 450‹ C. under pressure; the product comprises chiefly hydrocarbons together with some unreduced cresol. The products are suitable for use as a fuel in internal combustion engines.

Title: Improvements in Steam Generators
IPC: F22G5/04
Filed: 1967-02-01
Abstract: 1,179,441. Water tube boilers; preventing overheating of reheater tubes. FOSTER WHEELER CORP. 1 Feb., 1967 [2 Feb., 1966], No. 4833/67. Heading F4A. A marine water tube boiler 10 is fired by roof burners projecting into a front tube lined furnace combustion chamber (Fig. 1, not shown). The exhaust gases pass over a bank of steam generating tubes extending between upper and lower drums 26, 28 respectively, and into a rear upright convection pass 14 through lower opening 40. A fin tube wall 42 divides the pass 14 into main and by-pass passages 46, 44 respectively, the main passage containing the secondary part 52 of a two part superheater 48 through which steam flows in parallel to the exhaust gases, and a reheater 54 through which the steam flows in counterflow to the exhaust gases. The by-pass passage contains economizer section 64. The gases from both passages then pass over economizer section 81 in flue 74. An opening 58 extends through the partition wall 42 to allow gas to pass from below the main passage 46 to the by-pass passage 44 after passing over the primary part 51 of superheater 48. The primary superheater part 51 is itself by-passed by an additional by-pass passage containing a further economizer section 62 and control dampers 60. During normal operation, steam superheat and reheat temperature control is effected by regulation of dampers 60, 66 in the by-pass passages. On going astern, when vapour flow through reheater 54 is stopped, damper 66 is opened wide and shut off dampers 70 in main passage 46 closed to prevent gas flow therethrough. The combustion gases then pass through opening 58 to the by-pass passage 44. As damper 70 is closed, damper 79 linked to it by shaft 80 is simultaneously opened to allow cooling air or other gas from wind box 75 to pass over the reheater tubes 54. Variation of damper 60 continues to regulate the superheater steam temperature.

Abstract: 655,466. Turbine blades. SVENSKA TURBINFABRIKS AKTIEBOLAGET LJUNGSTROM. Feb. 19, 1948, Nos. 4936 and 4937. Convention dates, Oct. 17, 1947 and Nov. 14, 1947. [Class 110(iii)] [Also in Group XXII] In a blade ring for a radial-flow elasticfluid turbine or compressor, the roots 2 of the blades 1 and the grooves 3 in the supporting ring 4 are shaped so that the roots and the grooves may be brought into sealed engagement by a combined and substantially simultaneous axial and radial movement of the roots and supporting rings with respect to each other, no preliminary bending out or subsequent pressing down of the rims of the grooves being necessary. One method of assembly is shown in Fig. 2 in which the blades are assembled in a clamping device comprising rings 7 and 8, the diameters of which may be varied so that after suitably shaping the blade roots, the diameters of the rings may be first reduced and then increased. Alternatively, the blade ring may be assembled by heating the supporting rings and at the same time cooling the blades and then allowing the temperatures to equalize. The blade ring may be assembled by a combination of these methods. An auxiliary fastening such as the ring 25, Fig. 12, may be used to seal the joint between the blade roots and the supporting ring. Many modifications are described and illustrated.
