Title: Improvements in combined vapour generators and burners for heavy liquid hydrocarbons
IPC: F23C99/00
Filed: 1952-10-03
Abstract: 746,827. Vapour burners. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 3, 1952 [Oct. 6, 1951], No. 24826/52. Class 75(1). A vapour generator and burner combination for heavy liquid hydrocarbons comprises means for atomizing the fuel to a small particle size (less than 100 microns) by means of a single low pressure air supply, and an externally heated vaporizer for the atomized fuel-air mixture, the atomizer having a fuel jet-aperture and a further aperture, spaced from and coaxial with the fuel jet aperture for the mixture of fuel and low pressure air, said air being supplied to the space between the two apertures. Heavy liquid hydrocarbon, e.g. diesel oil, is discharged through an orifice 11 at the end of a supply pipe 10 and into a cup-shaped vaporizing chamber 1 through an aperture 5 in a cover member 4, air under low pressure, supplied through an inlet 9 to a chamber 8 surrounding the discharge end of the pipe 10, passing also through the aperture 5 to atomize the fuel entering the chamber 1 to produce fuel particles of less than 100 microns diameter. The vaporized fuel passes through passages 16 into burner swirl chambers 12 disposed in a circle concentrically surrounding the chamber 1, and carried by a member 15 in which the passages 16 are arranged eccentrically with respect to the chambers 12. Preheated air is supplied through an inlet 23 to a casing surrounding the combustion chamber 2 and passes through an opening 6 and passages 7 in the member 4 to be directed into the chambers 12 through tangential swirl passages 14. To avoid carbon deposit at the aperture 5 holes may be providedaround the aperture for the passage of air from the chamber 8, to be directed by a baffle adjacent the inner wall of the member 4 transversely across the fuel and air stream entering the chamber 4 through the aperture 5.

Title: Improvements in and relating to arc welding
IPC: B23K9/16
Filed: 1931-09-04
Abstract: 382,702. Uniting by fusion. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Chapman, V. J. ; 25, Lakewood Avenue, Schenectady, New York, U.S.A.) Sept. 4, 1931, No. 24894. Convention date, Sept. 4, 1930. [Class 83 (iv).] In an arc welding apparatus means are provided for feeding a sheet of shielding material in spaced relation to the arc to form an enclosure about the arc and joint. The material may consist of paper which is partly consumed by the heat of the arc to produce an atmosphere of carbon monoxide and carbon dioxide. It may also consist of asbestos, impregnated cloth or sheet metal. Paper &c. may be rendered non-inflammable by impregnating with kaolin, sodium silicate, &c., which also serve as fluxes, and powdered fluxing materials such as lime, calcium carbonate, titanium oxide, ferrotitanium may be applied to the paper or may be incorporated therein. A sheet of shielding material 12 may be fed over a roller 13 and through a guide 14 carried by the welding head so as to convert it into cylindrical form 15 around the electrode to form an enclosure. Feeding may be effected by serrated rollers 16 driven by worm gear and flexible shaft 20 from one of the electrode feed rolls 21 so as to maintain its lower end in contact with the work. In another form, Fig. 4, the sheet 23 may be drawn from a roll 24 through a folder 25 carried by the welding head so as to form it into arch shape during traverse of the head, by rollers 28 on frames 29 connected by springs 30 to the welding head. The rollers hold the material on the work and may also serve to clamp the work, or additional clamps may be provided. The flux 31 may be applied prior to passing through the folder and incorporated in the material by passage through the folder or it may be applied after application of sodium silicate which serves as a binder. The flux may alternatively be mixed with the sodium silicate and applied by an atomizer 32 from the nozzle 33 of which it is ejected by air supplied through a conduit 34. The sheet material may also be made up of two sheets enclosing a strip of fluxing material. In a further form, Fig. 6, the enclosure may be formed by feeding a flat sheet 38 over the work clamping bars 39 by the roller frames on the welding head. The work in this case may be held against the bars 39 by a flexible strip 43 forced up by plungers 44 on a distensible hose 45. The rollers on the frames may be replaced by springs 49 or by an elongated spring supported shoe or rollers and springs may be used conjointly. With a paper shield a path for the electrode is cut by heat of the electrode or arc. The material may be reduced in section or perforated for passage of the electrode or the welding apparatus may carry means for cutting or slitting the material. Specification 374,339 is referred to.

Title: Manufacture of mercurial phenols
IPC: C07F3/12
Filed: 1923-10-10
Abstract: Alkali salts of hydroxymercuriphenols are prepared by treating solutions of alkali salts of phenol or its homologues with freshly precipitated mercuric oxide and evaporating to dryness in a vacuum. The products are stable but may be made even more stable by adding to the solutions, before evaporating, salts capable of reacting with the -HgOH groups such as alkali sulphites or cyanides: they are intended for treating seed to destroy injurious bacteria and the like; for this purpose they may be mixed with neutral salts or other indifferent substances and dyestuffs may be added to the mixtures. According to examples products are obtained from freshly precipitated mercuric oxide and (1) phenol, caustic soda and sodium sulphite, (2) commercial cresol and caustic soda with and without sodium cyanide; in each case the mercury content of the product is adjusted to 17.5 per cent by addition of sodium sulphate or chloride and a dyestuff.

Class 100(2) In a duplicating machine employing a printing couple comprising a master cylinder 10 and a pressure roller 15 the pressure roller and a moistening pressure roller 17 are movable towards and away from the master cylinder and a moistening roller 16 respectively by the operation of an adjustable pressure applying device the movement being transmitted in the case of the moistening pressure roller 17 through means which provide the requisite contact pressure between the moistening pressure roller 17 and the moistening roller 16 despite adjustment of the contact pressure between the pressure roller 15 and master cylinder 10. The pressure roller 15 is carried by a pair of sheet metal lever members which are pivoted to the side frame members at 27 and interconnectd bv a bridge piece 25 of arcuate section. A manually controlled eccentric 30 bears through a roller 31 on the bridge piece 25 to apply the printing pressure. The pressure roller 15 is mounted' in slotted bearing washers 36 fitting in U-shaped gaps in the levers 33. Extensions 34 pivoted at 35 to the levers 33 carry bearing washers for the moistening pressure roller 17. The pressure of engagement between the roller 17 and the moistening roller 16 is governed by a soring 40. The moistening roller 16 is supplied with liquid by a felt 18 so that sheets passing between the rollers 16 and 17 are moistened. The felt is resiliently mounted in a housing 45, a transverse tube 46 having perforations along its length for supplying the liquid to the felt. For urging the felt against the roller 16 an arm is secured to one end of tube 46 and connected to a spring 48, an arm 47 in the middle of the tube 46 being adapted to bear down on the top of the housing 45.

Abstract: 1276757 Gasifying coal and oil RHEINISCHE BRAUNKOHLENWERKE AG and W. WENZEL 26 May 1970 [27 May 1969] 25322/70 Heading C5E Coal and/or oil is gasified at 12 with H 2  to pro - duce CH 4  which is converted with water vapour at 13 to a mixture of H 2  and CO. The CO is converted to CO 2  at 14 and the CO 2  is washed out at 15, H 2  being recycled to the gasifier 12. The CO 2  is delivered to a converter 16 where CH 4 , led off at 28, is converted to H 2  and CO optionally with extra CO 2  from 29. The heat for the various reactions is derived from a nuclear reactor 11, and ash is discharged at 37. In a modification, see Fig. 2 (not shown), the converter 16 is replaced by an apparatus (64) supplied with H 2  and CO (instead of with CH 4 ) from the methane converter (42), where CO 2  from the washer (56) oxidizes the H 2  and produces the required mixture of H 2  and CO. The gasifiers 12 (40) may be of fluidized bed type. The CO 2  supplied at 29 may come from an ore reduction process or from the partial combustion of coal or oil, and the H 2 O supplied at 23 may be derived by drying coal being charged at 18. The steps of converting the CH 4  with H 2 O and with CO 2  may be combined, the effluent gas being divided as product and for converting to H 2 .
