Title: Improvements in tubulous vapour generating and vapour heating units
IPC: F22G5/02
Filed: 1955-08-26
Abstract: 777,305. Forced-flow steam boilers. BABCOCK & WILCOX, Ltd. Aug. 26, 1955 [Aug. 27, 1954], No. 24537/55. Classes 123(2) and 123(3) In a forced-flow, once-through steam, &c. boiler operating at super-critical pressure of the general construction described in Specification 762,902 and comprising. a number of independently operable cyclone furnaces 10 arranged to discharge high temperature gases into a secondary furnace 14 whence the gases flow under an inclined baffle 16 and through a slag screen 20 into a vertical radiation chamber 22 lined with superheating tubes and discharge therefrom through a lateral pass 30 in which are disposed primary and secondary superheater sections 34, 36 respectively, the rear wall 26 of the radiation chamber extends vertically from the lower end of the slag screen 20 to the level of the upper end of the baffle 16 and then is inclined rearwardly in a section 26a to terminate in a curved section 26b which merges into the bottom of the convection pass. The front wall 24 of the radiation chamber forms in its lower portion a continuation of the inclined baffle 16, the front and rear walls diverging until the distance from the upper end of the section 26b to the wall 24 corresponds to the vertical height of the heating pass 30, the wall 24 then. continuing vertically to the roof 32 of chamber 22. An additional section 38 of secondary superheater is disposed in the form of pendent tube panels above the inclined rear wall section 26a so as to leave a substantial space between the lower ends of the tube panels and the said wall section. The arrangement is such that the tendency of the hot gases to crowd against the roof 32 with consequent uneven gas flow over the height of the pass 30 causing the overheating of the upper parts of the tubes 36 is overcome by the flow restriction provided by the tube panels 38 and the alternative free passage 37 provided for the gases. Furthermore, to bring the temperature of the gases entering the pass 30 below that at which fouling of the convection surfaces with sticky fly ash occurs and to avoid overheating' of the tubes 36. 38, cooled flue gas is withdrawn from opposite sides of the outlet duct 40 of the pass 30 by fans 66 which discharge through ducts 68 into a plenum chamber 74 whence the gas flows into the chamber 22 through damper-controlled ports spaced across the wall section 26 to mix thoroughly with the fresh combustion gases. The quantity of gas recirculated is controlled by varying the speed of the fans 66. To prevent back-flow of gas from chamber 74 into either fan if that fan is shut down, each duct 68 has spaced sets of shut-off dampers 86, 88 between which cooling air from a duct 90 can be admitted

Abstract: 671,993. Needle-threaders. FAIRWEATHER, W. C. (Singer Manufacturing Co.). Oct. 7, 1950, No. 24546/50. Class 112. A sewing-machine incorporates a needle threader which is self. adjusting to the position of the needle ; the threading element is mounted on a carrier which is movable lengthwise of the needle to bring the element into register with the needle eye and is swingable to project the element into the eye. In the embodiment shown, mounted in the face-plate of the machine head, a threading hook 13 is detachably secured to the lower end of a carrier 14 which is slidable in a slot in the face-plate and is guided by two pins 18, 19 engaging a slot 20 in one side of the slot; a slide-block 26 secured to the upper end of the carrier 14 carries a finger-piece 27, pivoted so that it can be moved to an out-of-use position shown in full lines. A vertically-sliding member 28 has a downwardly-projecting finger 37 for engagement with a shoulder on the carrier 14 and an upward finger 36 to engage the pin 18, and a fork 33 adjustably secured to it embraces the needle-bar above the block 35 to which the pitman 8 is connected. In operation, the carrier 14 is moved downwards by the finger-piece 27 until the pin 18 engages the finger 36 of the member 28, and then further, taking the member 28 with it, until the fork 33 engages the block 35, when the threading hook 13 is opposite the needle eye. Further pressure on the fingerpiece 27 then tilts the carrier about the pin 18, the pin 19 moving in a wider part 21 of the groove 20, to pass the hook 13 into the needle eye. On release of pressure the carrier is moved back to the vertical position by a spring-pressed lever 22, and is then lifted to the inoperative position, taking the member 28 with it by means of the finger 37; it is held in this position by a spring detent 39.

Abstract: 973,847. Printing surfaces. ROGERS CORPORATION. June 20, 1963, No. 24575/63. Heading B6C. A process for the production of plastic printing plates which comprises pressing a sheet of permeable and microporous synthetic thermoplastic resin material against a printing plate matrix having type cavities therein under conditions whereby the material flows into said type cavities to take up the configuration thereof. The sheet material, which may be produced from thermoplastic resins granules by the process of Specification 960,082, may comprise a composition containing one or more thermoplastic vinyl resins which are copolymers of vinyl chloride and vinyl acetate containing from 80-99% by weight of polyvinyl chloride and 20-1% of polyvinyl acetate. Inert fillers such as clays, wood flours, asbestos fibres and silicates, may be blended together with one or more of the resins. In a first example a sheet made by the process of Specification 960,082 from a copolymer of vinyl chloride and vinyl acetate containing 85-88% by weight of vinyl chloride and having an average molecular weight of 10,000 mixed with wood flour and carbon black pigment is cold-moulded into a printing plate by heating it for 2 minutes at 300‹ F. with contact pressure and moulding it for 3 minutes in a cool press at 1000 p.s.i. A variation of this example differs only in that the sheet is made from a copolymer of vinyl chloride and vinyl acetate containing 85-88% by weight of vinyl chloride and having an average molecular weight of 10,000 mixed with a copolymer of vinyl chloride and vinyl acetate containing 96-98% by weight of vinyl chloride and having an average molecular weight of 200,000. In a further example the sheet is made from the copolymers of the sheet of the second example to which are added wood flour and a pigment. The sheet is cold-moulded the heating time being 3 minutes at 300‹ F. whilst the moulding in a cool press lasts for 4 minutes at 1000 p.s.i. A similar sheet in yet another example is hot-moulded by heating it, via a heated platen, in the mould for 4 minutes at 280‹ F. and then increasing the pressure to 1000 p.s.i. for 5 minutes before releasing the pressure and allowing the plate to cool.
