Patent GB-703405-A (GB)
Abstract: 703,405. Solid-fuel stoves. VANACKER, A. A. C. L. Oct. 16, 1950, No. 25191/50. Class 126 A continuously burning stove using fuel such as lignite or peat has a hopper-in which the fuel is partially burnt to a limited depth to produce combustible gases which are mixed with secondary air and burnt in a space immediately adjacent the hopper, and part of the secondary air is fed to the combustion space by a horizontal passage closed at its upper part and forming the lower part of one wall of the hopper. In a hot-air stove, Fig. 1, a free space 8, open at top and bottom, is left between the hopper 3 and a smoke pipe 5 surrounding the hopper. Primary air traverses the column of fuel supported by an oscillating grate 2 from a slit 11 between a rear deflector plate and the top of the grate, and also enters the fuel through a slot 14 between a front deflector 13 and the grate, and through apertures 15 in deflector 13. Air is drawn through a horizontal flue 16 into a passage 17, one wall of which forms the lower front wall of the hopper 3, the other wall forming the lower wall of the smoke pipe 5. Gases given off by the fuel burning on the grate 2, are mixed with air from apertures 15 and outlet slot 18 at the bottom of passage 17 and completely burnt as they enter smoke pipe 5 and pass out at 21. A central-heating boiler stove, Fig. 2, has a fuel store 39, from which fuel reaches hopper 31 through distributer 40. Combustible gases leaving the fire supported by oscillatable grate 32 are mixed with secondary air issuing from apertures 31 in a rear slope member and from a chamber 54 as they enter a nozzle 49 leading to spaces formed between water circulation boxes in chamber 43. Combustion is completed in nozzle 49 and the waste gases escape at 48. The furnace may have double side walls with water circulation. In a cooking range, Fig. 5, secondary air is admitted through a passage 77 having a common wall with the hopper and through an aperture 76. The cooker has an oscillating grate 78 similar to those used in the embodiments of Figs. 1 and 2 comprising two sets of similar elements mounted on parallel square shafts. Each element has a tooth forming half a grate bar and a sector diametrically opposite the tooth. The shafts terminate in spindles freely rotatable in uprights rigid with the wall of the stove, and carry co-operating toothed sectors so that the shafts may be rotated in opposite directions. Cinders collected at the bottom of the chambers formed by the grate teeth are ground between them when the shafts are rotated, and the cylindrical. surfaces of the sectors retain the incandescent fuel when the cinders are dumped.

Title: Anti-siphon trap
IPC: E03C1/29
Filed: 1978-07-24
Abstract: The invention relates to an anti- siphon trap suitable for use in waste-water disposal plumbing systems. Previously known anti-siphon traps suffer from disadvantages such as noisiness during operation and complexity of construction. The present invention provides an anti-siphon trap comprising a housing (1,2) having an inlet (4), a passage (15) extending downwardly from said inlet (4) and an outlet (6) disposed above the bottom outlet (16) of said passage (15), characterised in that at least two conduits (12) are provided each extending downwardly from an upper opening (13) in communication with the exterior of the passage (15) to a lower opening (14) in communication with the interior of the passage (15), at a level above the bottom outlet (16) of said passage (15). In a trap comprising a housing 1-2, an inlet dip tube 5 and an outlet 6, the lower end of the tube 5 is enclosed by a push-fit members 3-8 which, in conjunction with the exterior of tube 5, provides two lateral vertical conduits 12 subdividing the lower housing 2 to quieten the trap. The member 3-8 has shoulders 11 and thus extends and restricts the bottom opening 10 of the dip tube. <IMAGE>

Title: Duplicating stencil
IPC: B41N1/24
Filed: 1978-08-01
Abstract: A duplicating stencil is produced by placing an electrostatically- produced image on a substrate (14) in contact with an ink-impervious surface layer (12) of a stencil blank (10), bonding the image to the surface layer by the application of heat and/or pressure and stripping the substrate from the stencil blank to remove the surface layer in the image area. The surface layer (12) may comprise a synthetic resin composition containing a finely dispersed pigment and be attached to the porous base tissue of the stencil blank by an adhesive. Bonding of the image to the surface layer and possibly also fixing of the image to the substrate in the same operation can be effected by means of infra-red heating. <IMAGE>
