No. 24900.—9th September, 1908.—ALEXANDER JOHN ARBUCKLE, of 1 Main Street, Belgravia, near Johannesburg, Transvaal, Mechanical Engineer, and ALFRED OSBORNE, of 1 Main Street, Belgravia, aforesaid, Mine-manager. Improvements in means for separating comminuted ores or other solid matter from liquids.

Extract from Specification.—For the carrying-out of the invention we may employ an inverted conical tank, or other vessel having inwardly or downwardly inclined sides for the whole or any suitable portion of its height. Into this tank or vessel the mixture of solids and liquids is conducted, the settlement of the solids taking place therein while the liquid overflows. The vessel is provided with an aperture at the bottom, through which the solids are withdrawn. This aperture is partially closed by means of a rotatable drum or cylinder, or drums or cylinders, extending the full length of said aperture. The drum or cylinder, or drums or cylinders, may be covered with canvas or similar material, or be otherwise provided with a roughened surface to facilitate the withdrawal of the solids from the vessel. Means are provided for making a liquid-tight joint between the vessel and the drum or cylinder, or drums or cylinders, to prevent egress of the mixture when the apparatus is being put into operation. Means may be provided for scraping off the solids which adhere to the surface or surfaces of the drum or cylinder, or drums or cylinders, and if desired a liquid supply may also be provided for washing said surfaces.

No. 24901.—9th September, 1908.—FREDERIC HENRY TREVELLIAN, of 256 Lambton Quay, Wellington, New Zealand, Cash-register Expert. Improvements in cash-registers.

No. 24905.—10th September, 1908.—The Westinghouse Metal Filament Lamp Company, Limited, of 2 Norfolk Street, Strand, London, England, Manufacturers (assignees of Anton Lederer, Ph.D., of 83 Atzgersdorf, Vienna, Austria). Improved process for the production of tungsten filaments for electric incandescent lamps.

Claims.—(1.) The process for the manufacture of tungsten filaments for incandescent electric lamps, which consists in treating with hydrochloric acid the reaction-product obtained as an intermediate product in Delépine’s process for the production of tungsten, washing with water, concentrating by evaporation until a plastic mass is obtained, and squirting therefrom filaments which are afterwards finished in the usual manner, substantially as described. (2.) The process for the manufacture of tungsten filaments for incandescent electric lamps substantially as described.

(Specification, 1s. 6d.)

No. 24906.—10th September, 1908.—JAMES THOMAS HUNTER, of Queen’s Chambers, Wellington, New Zealand, Patent Agent (nominee of Linotype and Machinery, Limited, of 188 and 189 Fleet Street, London, England, the assignees of Herbert Pearce and John Ernest Billington, Engineers, both of Linotype and Machinery Works, Broadheath, Chester, England). Improvements in typographical composing-machines.

Extract from Specification.—This invention relates to typographical composing-machines, composing matrices or type dies, irrespectively of whether the ultimate result of their operation be linotypes, lines of type, or only stereotypers’ matrices, and which machines are of a type characterized by a tier of magazines, each carrying its own escapements, the said tier interposed between a single keyboard, a single set of connections therefrom to the escapements on the magazines, and a single assembler-entrance on the one hand, and a single magazine-entrance and a single distributor on the other, and means for moving the tier up and down to effect a “quick change”—i.e., to quickly make the one containing the desired fount (or substituted magazine) register with the assembler-entrance and the magazine-entrance. It is characterized by certain improvements in the tier of magazines; in the “quick change” mechanism, in means for balancing the weight of the tier during a “quick change”; in means for insuring exactness of register on the part of a substituted magazine after each “quick change”; and in the co-operation of the magazine-entrance with the tier of magazines. One object of the invention is to effect improvements in the Mergenthaler linotype machines described in the specifications of British Letters Patent Nos. 9570 of 1897 and 15058 of 1904 in respect of the escapements of the former, and in the connections between the keyboard and the escapements of the latter. The application of the invention to a Mergenthaler linotype machine has been chosen for specification as the best means of making the nature of it clearly understood.

(2.) The combination with a box or case having threaded studs projecting from the upper edge of one end thereof and a metal band secured above the upper edge of the other end, of a lid having one end bevelled to fit under said metal band, and its other end formed with recessed portions having holes therein through which said studs pass to receive nuts to be screwed up thereon to secure the lid in position, substantially as described. (3.) The combination with a box or case having threaded studs projecting from the upper edge of one end thereof and a metal band secured above the upper edge of the other end, of a lid having one end bevelled to fit under said metal band and its other end formed with recessed portions and fitted with a correspondingly recessed metal band, said recessed portions and band having holes therein through which said studs pass to receive nuts to be screwed up thereon to secure the lid in position, substantially as described. (4.) Improvements in or relating to boxes and cases consisting of the parts combined, arranged, and operating, substantially as described or illustrated in the drawings.
