Title: Improvements relating to the production of solid fuel by briquetting and heat-treating
IPC: C10L5/02
Filed: 1932-04-30
Abstract: 391,975. Materials for making coke. M E R K E L, G., 53, Hiltensbergerstrasse, Munich, Germany. April 30, 1932, No. 12505. Convention date, May 1, 1931. [Class 55 (ii).] Smokeless briquettes are made by mixing non-caking fuels such as anthracite, semi-coke bituminous coals, lignites, &c. in granular form with finely ground caking coal and briquetting with just such an amount of binder, e.g. pitch, as to render the briquettes resistant to stresses before and during coking whilst embedded in neutral refractory material such as small coke. The distillation temperature may vary from 600-1000‹ C. The binder, e.g. 1-2 per cent of pitch, is desirably ground with the caking coal which is preferably gas coal containing 28- 38 per cent of volatiles. Or the binder may be liquefied and brought in the form of a mist into contact with the caking coal. About 10 per cent of caking coal is used with poor fuel while material richer in volatiles require 20-25 per cent or more. Specifications 27167/13, [Class 50, Fuel, Manufacture of], and 294,581, [Class 55 (i), Coking &c.], are referred to.

In a sifting apparatus comprising a fixed cylindrical sieve 17 and a rotary impeller 29 in which the supply from the hopper 23 is controlled by a rotating, automatically adjustable spreader cone 33 (see Group II) the main driving shaft 26 is reduced at its upper end to be a sliding fit within a sleeve 37 supporting the cone 33 and a plate 27 which carries the impeller is bored to fit the main diameter of the shaft 26 and is provided with a recess to accommodate a circular plate 48. The plate 48 fits over the reduced portion of the shaft 26 and has two diametrically opposed slots 49. A driving pin 50, preferably of square crosssection, passes through the reduced part of the shaft 26 and the slots 49 allow the plate 48 to pass over the pin 50. A driving plate 30 is bolted to the plate 27 and holds the plate 48 in position, a taper pin 51 through the plates 27, 48, 30 preventing relative movement between the plates. The plate 30 has an aperture of the same size as the reduced portion of shaft 26 and has two diametrically opposed quadrants 52 removed to form driving dogs which engage with the pin 50. To place the impeller in its working position the plate 27 is slid on to the upper portion of shaft 26 and rotated until the slots 49 coincide with the pin 50, and the plate 27 then falls downwardly until the plate 48 makes contact with the main part of shaft 27. The plate 27 is then rotated through 90 degrees until the driving pin 50 abuts the sides D of the dogs, and the pin 50 then prevents upward movement of the impeller. The lower end of the sleeve 37 is provided with projections 53, Fig. 12, which rest between the driving pins 50 and faces E of the dogs, and prevent rotation of the impeller relative to the shaft 26 as long as the sleeve is in position.

Abstract: 1,246,211. Seaming non-metallic sheet material. COMPAGNIE FRANCAISE DE RAFFINAGE. 13 March, 1969 [13 March, 1968], No. 13354/69. Heading B5K. Two contacting sheets 1, 2 of butyl rubber are welded by subjecting the sheets to ultra-high frequency electromagnetic radiation of at least 900 MHz to raise the temperature thereof and pressing the sheets together. The term "butyl rubber" denotes a synthetic rubber produced by the copolymerization of isobutene with a small amount, e.g. 2% by weight, of isoprene or butadiene. As shown, the overlapping sheets 1, 2 are pressed together by electromagnets 3, 4 cooperating with a metallic strip 5. An antenna 7, connected by a coaxial cable 6 or a flexible waveguide to a generator of ultra-high frequency electromagnetic radiation, e.g. an electromagnetic induction coil or a magnetron oscillator providing electromagnetic radiation of 2000 MHz, directs the radiation into the sheets. The radiation is stopped when the zone being heated has reached 150-250‹ C., preferably 180-220‹ C., and the pressure is continued until a weld has formed. The assembly of the antenna 7 and the electromagnets 3, 4 are advanced over a distance equal to the length of the antenna 7 and a new welding cycle is begun. The operation is repeated until the sheets 1, 2 are welded along the entire length.
