(3.) A mitre box and cramp comprising, in combination, a base-plate having its back edges formed as arcs of circles, saw-guides mounted centrally across said base-plate, flanges with longitudinal slots formed on said back edges of said base-plate, adjustable fences pivoted at their inner ends on said base-plate at points corresponding to the centres of said circles and having their outer ends turned down over said flanges, means on said adjustable fences for engaging said slots for clamping said outer ends to said flanges, clamps for holding moulding against said fences, and means for drawing said clamps towards said fences, substantially as described. (4.) In a mitre box and cramp of the class described, wedge-pieces with stepped outer faces adapted to fit on the moulding-clamps, substantially as and for the purposes set forth. (5.)

No. 22362.—28th January, 1907.—WILLIAM EVANS, Flour-miller, and DAVID YOUNG CUNNINGHAM, Carpenter, both of Timaru, New Zealand. An improved joint for weatherboards.

Extract from Specification.—In the present invention the joint is constituted by forming the upper outer edge of each board with an approximately square-cornered groove extending along it, and the inner lower edge with a similar groove. When making the joint the two grooves are brought together so that the inner upward projection left by the upper groove will extend upwards behind the board above, while the outer downward projection left by the lower groove will extend down over the front face of the board below. Thus a surface will be formed similar to the surface obtained by the ordinary jointing.

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

Process of work and combination of apparatus intended to extract by hot air the solid particles contained in the natural fluids or solutions useful for all practical purposes and especially in dessicating milk and extracting sugar from sweet liquids.

Claim.—The application for the concentration, crystallization, or extraction by drying by hot air of the solid matters contained in the liquids, of the process and apparatus above described, consisting of the ensemble of means exposed, ensemble determined hereinafter contributing in each case to obtain crystals, a dry or concentrated product either under a new form and with new properties, as for the milk-powder natural, fine, and soluble in cold water, or by a simple and economical means forming a real progress as the sugar of the sweet juice or the dry particles contained in solutions or in natural liquids, the ensemble of those means being constituted successively by direct-compression pulverisation without addition of air, in the form of a fog by very small orifices (0·3 to 0·L millimeter in diameter), and instantaneous drying at a relatively low temperature (from 60° to 99° centigrade, according to the case) of the said liquids producing no alteration, economical utilisation of the heat, considerable reduction of moisture in the product obtained, the greatest obtainment
