[Class 82 (ii)] Coal is concentrated by a gravity separation process carried out in an aqueous sludge of barytes and clay, the proportions being selected to produce a separating liquid of the desired specific gravity. A slight upward current is preferably produced in the upper part of the concentration vessel and a slight downward current in the lower part of the vessel. Coal is fed by a shoot 2 to a vessel 1 containing an aqueous sludge of barytes and clay, and is uniformly distributed in the bath by the drum 4<1>. The lower end of the vessel 1 is connected to a housing in which works a bucket conveyer 9 which removes the gangue. Liquid is withdrawn from the conveyer housing through a pipe 14 connected to a pump 18 which also withdraws liquid through a pipe 17 from an extension 16 at the top of the vessel 1. The amount of liquid withdrawn can be controlled by valves 12 and the liquid is returned by the pump 18 to the vessel 1 by means of a pipe 19, an annular conduit 20, and openings 21. The circulation is adjusted so that a slight upward current is produced in the vessel 1 above the openings 21 and a stronger downward current below these openings. The floating coal is removed by an endless rake conveyer 5 which carries the coal up a perforated deck 22 from which the liquid drains back into the extension 16, the coal being discharged into a hopper 6. The Specification as open to inspection under Sect. 91 describes the apparatus which forms the subject-matter of Specification 420,427. This subject-matter does not appear in the Specification as accepted.

Title: Method and means for producing typographic line blocks and line blocks obtained therethrough
IPC: B41B11/52
Filed: 1953-06-08
Abstract: 727,860. Type-bar-making machines; printing-surfaces. BACOT, F. June 8, 1953 [June 20, 1952], No. 15755/53. Classes 100 (1), 100 (2) and 100 (3). A method for the production of typographic line blocks consists in composing in a conventional manner a line of matrices on a composing machine, laying in front of the matrix line a thin and yielding section of a strip of plastic material, softening the section of the strip registering with the matrix line and submitting it to pressure so as to mould the strip section on the surface of the matrices, and securing the line block constituted by the strip section carrying the impression of the matrices to a yielding support which serves for the making up of the final page. A thermoplastic strip 1, Fig. 1, is fed intermittently past a moulding station A and a strip-mounting station B. A line of matrices and spacers 3 is clamped against an electrically conducting abutment 4. A highfrequency generator 3a is connected to the matrices and to a pressure plate 7 reciprocable by a cam 9. When the plate 7 is advanced against the matrices, the strip 1 acts as a dielectric and is heated by the dielectric losses incurred, so that the characters are moulded into the strip. At the station B, the moulded section of the strip lies between a bearing member 28, Figs. 1, 2 and 3, and a frame 13 reciprocable by a cam 15. Between the strip 1 and the frame 13 passes a strip 18 of adhesive canvas and an endless yielding supporting strip 19 of fabric, both of which are fed intermittently downwards. When the frame 13 moves forwards, knives 35 enter recesses 36 in the member 28 to sever the moulded section into a line block, which adheres to the canvas strip 18. The strip 18 thus eventually carries a series of such line blocks 50, and is cut to lengths corresponding to a typographic composition, such as a page of text or a newspaper article. Such compositions can then be assembled and glued onto a common canvas sheet of a size corresponding for example to a newspaper sheet, and usable directly on a rotary printing-machine. For repeat printing, two stations B may be provided, the strip moulded twice from the same matrix line, and the two similarly moulded sections brought one to each of the stations B. Feeding-webs.-A pair of jaws 38, 44, Figs. 1 and 4, are carried on arms 37a, 37b pivoted to levers 39, 47 and controlled by cams 42, 49 and springs 41, 48. During a machine cycle, the cams first recede to cause the jaws to advance through the station B, riding up a sloping surface 34, Fig. 3, of the member 28 and forcing the member to slide downwards against a spring 30 on guides 29. When the jaws reach the end of the strip, the cam 49 causes a further advance of the arm 37b to close the jaws on to the strip, whereupon the jaws are withdrawn with the strip to the position shown in Fig. 1. After the severing of the strip, the jaws are opened.
