No. 22095.—21st November, 1906.—WILLIAM BELL, of Redan Street, and HARRY BRYCE BELL, of Cowles Road, both of Mosman, near Sydney, New South Wales, Australia, Photo-engravers. An improved manufacture of half-tone printing-blocks.

———

Extract from Specification.—This invention mainly consists in forming the printed surface of a block in relief by subjecting it to a yielding pressure, obtained by using a plastic sheet, such as lead, leather, or guttapercha, in a pressure-press, the back of the block having previously been prepared and weakened on certain predetermined parts corresponding to the high lights and half-tones on the printed surface to permit of the buckling or depressing of these weakened parts, or by subjecting to pressure a comparatively thin shell of metal—upon which a print has been developed and burnt in—superposed upon a mould or die the surface of which is formed with depressions corresponding to the high lights and half-tones of the superposed plate, into which depressions the overlying portions of the thin plate are forced.

[NOTE.—The above extract from the specification is inserted in place of the claims.]

(Specification, 11s.)

No. 22227.—20th December, 1906.—DAVID HOUSTON, of The Terrace, St. George, Queensland, Australia, Hotel-manager. An improved acetylene-gas generator.

———

Extract from Specification.—This invention has been devised with the object of providing an acetylene-gas generator which, while being simple and cheap to manufacture, is very efficient and is quite safe. To this end, on the side of the generating-chamber, which may be of any suitable shape, and near its upper end, is formed a lip or chute, which leads to an opening in said chamber somewhat below the level of the contained water. Through this opening the calcium-carbide is fed from carriers or boxes arranged to work by preference automatically. About the inside of this opening flanges or other means are provided to prevent the escape of the rising gas. Surrounding the protruding gas-outlet is formed a cup or the like whereby the main outlet-pipe leading to or from the gasometer is loosely jointed by water-seals, and thus a further safety device is formed.

[NOTE.—The above extract from the specification is inserted in place of the claims.]

(2.) In a wire gripper and strainer, the combination of a bent bar A furnished with a male screw-thread B passing through an iron plate C furnished with a female screw-thread for the reception of male screw-thread B, such plate being also furnished with bars DD terminating in hooks, another plate E affixed to bar A at end of male screw-thread B, such plate being furnished with recesses FF, studs GG, and outer plate I, substantially as described and illustrated. (3.) The general arrangement, construction, and combination of parts composing my wire gripper and strainer, substantially as described and illustrated.

———

Claims.—(1.) The improved process of filtering slimes which consists in filling a vat therewith, drawing off the liquid contained therein through a filtering-surface carried in said vat, creating and maintaining a maximum vacuum in the filtering media until a cake of slimes is formed upon its surface, diminishing the vacuum, discharging the non-adhering slimes from the vat, filling the vat with a reagent and increasing the vacuum until same is drawn through the caked material,
