No. 28297.—19th August, 1910—THEODORE UMRATH, of Chicago, United States America (temporarily residing at Auckland, New Zealand), Engineer. An improved rotary vacuum pump.

Extract from Specification.—The invention lies principally in fitting a conical tapered valve on the two ports of the vacuum pumps in the manner detailed, whereby the inward draught and outward rush of air can be so regulated that the valve action will be almost noiseless.

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

No. 28298.—19th August, 1910—WILLIAM HENRY JONES RIDLEY, of Penrose, Auckland, New Zealand, Engineer, and MALCOLM JOHN CONNOR, of the said City of Auckland, Engineer. Improvements in a process for extracting gold or other metals from sands or other matter deposited on beaches and foreshores and from other deposits.

Extract from Specification.—The first step is for drying the sand or material to be treated where there is water or moisture in it, and for this purpose an apparatus is provided consisting of an iron casing containing a hopper, retorts, flues, and other parts, which when the sand or material is passed through them leaves such sand or material quite dry. The second step is for separating the magnetic oxide from the sand or material and so to prepare it for the final treatment. In this second step a hopper and magnetic cylinders and other necessary parts are provided, so that after the sand or material is passed over the magnetic cylinders and the magnetic oxide has been withdrawn from it the remainder is in a fit state to be dealt with by the third step. The third step is for separating the gold and metal from the sand or material, which is done by passing such sand or material into a hopper, from which it falls on to a belt, preferably made of steel, moving in an upward direction, and which is given an oscillating and intermittent motion by an eccentric actuation of the whole frame carrying such belt and other parts. The result of this treatment is that the gold or metal is separated, and is ready to be dealt with commercially.

No. 28372.—1st September, 1910.—HENRY ALLOTT, of Te Akatea, New Zealand, Farmer. An improved method of ventilating the sunken ends of fencing and other posts and of holding battens.

Extract from Specification.—The object of this invention is to ventilate the sunken ends of fencing and other posts so as to preserve them and save them from premature decay, and to hold fencing-battens in place. The way in which this result is obtained is to leave spaces round the post and to partly pack in between the post and the ground in such a way that the air can get in and around the portion of the post which is sunk beneath the surface of the ground, and to hold the fencing-battens securely to the ground without sinking them into the ground.

No. 28388.—5th September, 1910.—HERBERT PHILANDER EWELL, of No. 38 Prentis Avenue Detroit, Wayne, Michigan, United States of America, Chemist. Method of making liquid sodium amalgam.

Claims.—(1.) Method of making liquid sodium amalgam which consists in introducing sodium into mercury excluding air therefrom at the point of introduction, and maintaining an excess of mercury over the sodium at the point of union of said elements.

[NBT.—Here follow four other claims.]

(3.) A brake-shoe having its curved braking-surface formed with a longitudinal groove adjacent to one edge, and with a plurality of pockets opening to said groove, and provided with a filling of refractory material of any character.

No. 28404.—8th September, 1910.—FREDERICK JOSEPH RICHARD FLOYD and ISAAC SAUNDRY BARRATT FLOYD, both of Carisbrook, Victoria, Australia, Cyaniders. Method of and apparatus for removing slimes, sand, or other similar material from one position to another.

Claims.—(1.) In the removal of slimes, sand, or other similar material from one position to another, the method set forth, consisting essentially in the employment of a rope or band to which is attached a scoop, the latter being drawn over the material to be removed so that it scoops in a load thereof, and then by reversal of pull of such rope capsizes longitudinally and is drawn up an incline and discharges its contents at the required position, and is returned and again longitudinally capsized to enable it to scoop in another load, substantially as and for the purposes set forth.

[NBT.—Here follow three other claims.]
