Title: A process and apparatus for the production of non-smoking fuel from agglomerates of rich coal
IPC: C10L5/28
Filed: 1935-10-29
Abstract: 464,989. Carbonizing fuel briquettes. KOPPERS' INDUSTRIEELE MAATSCHAPPIJ NAAMLOOZE VENNOOTSCHAP, H. Oct. 29, 1935, No. 29870. Convention date, Oct. 29, 1934. [Classes 51 (ii) and 55 (i)] Briquettes made from agglomerated bituminous coal are first oxidized at a temperature insufficient to expel hydrocarbons, and below the softening point of the coal, after which they are heated in the absence of air to a higher temperature to harden the fuel. The agglomerates are oxidized in a chamber 3 by the passage of oxidizing gases at about 200‹ C. for about four hours, and are then fed into a hardening chamber 8 externally heated to between 550 and 750‹ C. steam being admitted through pipes 25. Hot flue gases from the retort setting 9 pass partly through duct 15 to pipe 17, and partly through pipe 21 to a steam generator 22, and by pipes 23 to rejoin the other gases, whereby their temperature is regulated. A fan 20 supplies air through a pipe 19, the mixed air and flue gases passing by pipe 5 into the oxidizing chamber 3. An extractor fan 28 ensures the passage of the gases and their withdrawal by pipe 27. Steam from the generator 22 passes by a pipe 24 to the bottom of the chamber 8. The retort chambers 8 are heated by gas burners 11, the hot combustion products rising in flues 10, Fig. 2, and passing down flues 12 to outlet flues 13, the flues 10 and 12 being interconnected by passages 14 so that some of the gases may pass back into the flues 10. By this means a uniform heating of the retort is obtained over its whole length.. The upper . part of the retorts 8 are heated by flues 33 communicating with the heating channels 10 by openings 35. The Specification as open to inspection under Sect. 91 describes also the application of the process to particles or pieces of coal. This subject-matter does not appear in the Specification as accepted.

Abstract: 220,208. Fiedler, S. O. A. Nov. 29, 1923. Feed-water, heating.-Feed water is heated by direct contact with steam at a constant pressure and then freed from air in a chamber open to the atmosphere. Steam is admitted through a regulating valve 1 which is controlled by the pressure within the apparatus acting on a piston 22, so that such pressure is kept constant. The heater 3 is divided into four chambers 4, 6, 9, 10, and feed water to be heated is supplied from a tank 26 to a perforated pipe 7 in the chamber 4, so that it is heated by contact with the steam. The water falls through a perforated plate 8 into the chamber 6, and is forced by the steam pressure into a chamber 9 from which it overflows into chamber 10. The inflow of water is controlled by a valve in the pipe 27, operated by a float 23 so that the level in the chamber 10 is below the top of the partition. The chambers 9, 10 are in communication with the air so that the gases liberated from the water may escape. A modified apparatus is described, in which the feed water is supplied by a pump 30. The surplus water then overflows from the chamber 10 through an intermediate chamber 12 to a suction vessel 13 connected to the main feed tank 15 and to the pump 30 while the chamber 10 is connected directly to the main discharge pump 31.

Abstract: 1,019,995. Recording-apparatus. HONEYWELL Inc. Aug. 8,1962 [Aug. 11, 1961], No. 30417/62. Heading G1J. A method of recording the variations of a phenomenon with time comprises deflecting a high-intensity spot of radiation across a chart 3 that is sensitive to that radiation thereby to produce a latent trace on the chart, and then causing the latent trace to become visible by first subjecting the chart briefly to low intensity radiation including the wavelengths to which the chart is primarily sensitive followed by exposure to high intensity radiation also including substantially the same wavelengths. A beam of radiation 5 from a super-high-pressure mercury-vapour lamp 7 in a quartz envelope is concentrated by a collector lens, reflected by a control mirror 8 to a spot intensity control filter 9, through the lens of galvanometer 6 to its mirror and back through the lens to mirror 10 and 11 to the paper 3 to record a latent image. An amber - coloured window 12 shields the viewer's eye from direct exposure to the high energy ultra-violet beam. Ambient light and radiation from a lamp 13 co-operate to latensify the latent image. The lamp 13 includes two fluorescent tubes, one tube 14 providing cool white light and the tube 15 high intensity ultra-violet radiation. For rapid latensification at paper speeds from 2 to 8 inches per second, all direct rays from lamp 13 should not strike the paper 3 nearer than an inch below the amber window 12, at higher speeds the interval should be increased. Radiation from lamp 15 should not strike the paper 3 until it has been exposed to the full intensity of lamp 14 after having been exposed to indirect light. Papers are available sensitive to wavelengths between 3000 A‹ and 5000 A‹ but wavelengths between 3000 A‹ and 4000 A‹ are most effective in producing traces, in desensitizing the background at low intensities and in latensifying latent images. Different arrangements of lamps are suggested and a single lamp with a graduated light filter may be used.
