Title: Improvements relating to imitation fires
IPC: F24C7/00
Filed: 1930-11-21
Abstract: 361,608. Imitation fires. FALKIRK IRON CO., Ltd., KENNARD, H. J., KINNES, A., and ERSKINE, J. H., Falkirk Iron Works, Falkirk, Stirlingshire. Nov. 21, 1930, No. 35068. [Class 126.] The " fuel is arranged in two or more zones spaced apart, e.g. 15, 16, 17, and the upper or forward zone or zones are so provided with apertures 24 that the visible portions of the other zone or zones are only seen through such apertures thereby giving the fire when illuminated a realistic appearance of depth. Non-flickering lights are used, such as 18 for the outer surface and 20 .. 23 for the surfaces of the inner zones. A glowing or flameless fire is thus simulated. The fuel layers are made of opaque material and simulate unburnt fuel combined with partially burnt fuel and ash and when unilluminated the appearance of a partially burnt-out fire is obtained. In the case of an " interior " fire, a gap at the rear allows a glow to be produced on the fire back.

Title: Improvements in and relating to the carbonization of coal
IPC: C10B53/08
Filed: 1929-11-16
Abstract: 340,717. Coking processes. NA. TIONAL FUELS CORPORATION, 117, Liberty Street, New York, U.S.A.-(Assign. ees of Berry, G. A.; 515, West Union Avenue, Bound Brook, and Beardsley, A. P. ; 1412, Evergreen Avenue, Plainfield, both in New Jersey, U.S.A.) Nov. 16, 1929, No. 35106. Convention date, Nov. 16, 1928. [Class 55 (i).] Bituminous coal is converted into a product resembling anthracite, and a yield of liquid distillates and gases is obtained, by passing successive currents of heated gas through the charge. Of four stages, the first rapidly raises the charge to between 275‹ and 400‹ C., or until appreciable amounts of hydrocarbon vapours are evolved, the second removes most of the hydrocarbons condensable at ordinary temperatures, a temperature of 500‹ C. being gradually approached, the third is a rapid rise to 600‹ to 900‹ C., and the fourth is a cooling stage. The charge is contained in retorts 1, through which the gases are passed in a circuit including a heat accumulator 11, boiler 14, superheater 27, and gas mixing chamber 41. By suitable adjustment of the valves in the various conduits so as to control the proportion of gases passing through the boiler 14 in which they are cooled, and the superheater 27, the desired temperature may be obtained in the retorts 1. Surplus gas is passed through a cooler 17 to a holder 18, and condensates are recovered in a cooler 23A, which operates in conjunction with a superheater 23 from which the stripped gas is returned to the heating circuit. In a modification, the heat accumulator 11 is dispensed with, and the retorts 1 are duplicated, one set when at its maximum temperature being cooled by gases which recover the heat for use in treating the fresh charge in the other set. A suitable charge is obtained by briquetting bituminous slack. Reference has been directed by the Comptroller to Specifications 236,151, 276,407, and 283,259, [all in Class 55 (i), Coking &c.].

Title: Improvements relating to actuating mechanisms for removable covers
Inventor: DOLAN HARRY
IPC: E05D15/00
Filed: 1953-12-23
Abstract: 758,741. Multiple fastenings. ENGLISH ELECTRIC CO., Ltd. Dec. 23, 1954 [Dec. 23, 1953], No. 35703/53. Class 44. Relates to actuating mechanisms for moving a cover member over an opening in an enclosure member, in the plane of the cover member, between a position in which fastening members on the cover member and on the enclosure member overlap each other to retain the cover member in position and a position on which the fastening members are clear of each other. According to the invention, the mechanism comprises at least one bolt member slidably mounted on the inside of the cover member for axial movement in the opening and closing directions of the cover member, the length of the bolt member or members being such that with the cover member in position on the enclosure member, no appreciable axial movement of the bolt member or members is possible, and an eccentric mounted on an operating shaft projecting through the cover member, the eccentric being arranged to co-operate with the bolt member or members, whereby rotational movement of the operating shaft creates a reaction between the bolt member or members and the cover member which results in the cover member being moved between the engaged and disengaged positions of the fastening members depending on which way the operating shaft is turned. As shown, a door 10 of a flameproof box 34 is provided with an operating shaft 13 the outer end of which is engageable by a socket spanner 17 and the inner end of which carries an eccentrically disposed plug 19 on which is mounted eccentrically to the plug, an eccentric 20. The eccentric operates on a bearing block 21 secured to the eccentric by a washer 22 and the block 21 is arranged to slide on a plate 25 to which is attached two bolts 30 slidable on blocks 31 welded to the back of the door, the opposite ends of the bolts engaging the inside surfaces of the box. Rotation of the shaft 13 in one direction effects an upward movement of the door, due to the reaction between the bolt ends and the box, to disengage wedge members 35 disposed along the top of the door from a flange on the box and to move the door clear of wedged members 36 along the bottom of the box, thus to free the door, from the box. The door is secured in position on the box by rotation of shaft 13 in the other direction after the door has been applied to the face of the box. In the closed position, the eccentric is moved past the dead centre position to render the mechanism self-looking. The eccentric may be angularly adjusted on the plug 19 which is splined for the purpose, to permit adjustment of the position of the cover relative to the box. According to the Provisional Specification, the invention is applicable to the flameproof housing disclosed in Specification 709,719.
