and recording-instrument, the circuit being closed by wires to earth, one from each alarm-box and one from the second annunciator. From each “alarm-box” or “call-point” circuit connected to the first annunciator a branch wire is taken (one from the outgoing and one from the incoming point), the two branches joining each other at a battery, which is wired to the second annunciator, which, in turn, is wired to earth. The result is that when both circuits are in order the two annunciators operate, and the two recording-instruments register one after the other, and when the closed circuit wiring or line is broken the broken remainders with the earths can be switched in to form an operative open circuit, which actuates the second annunciator and recording-instrument and causes the latter to register. My invention thus provides a reserve system in case of line-breaks in the usual system.

(2.) An improved two-wheeled vehicle brake or check, constructed by mounting a horizontal shaft or bar across the under-framing of the vehicle in front of the wheels thereof, said shaft or bar carrying at each end arms adapted to operate the checking-means on the wheels, also trace-arms secured on the shaft or bar and projecting diagonally downwards towards the front of the vehicle, and a lever or like means mounted on the shaft or bar and adapted to engage in a rack, in the manner and for the purpose set forth, as described and illustrated.

No. 29685.—6th June, 1911.—JOHN CHARLES SMITH, Smelter, and WILLIAM TWEEDALE, Smelter, both of New Plymouth, New Zealand. An improved process for the extraction of metals from material containing them.*
Extract from Specification.—The invention consists in the employment of zinciferous substances, first as a collecting agency for the separation of the gold, silver, and platinum contained within the material, or as a fluxing or reducing agent in a smelting-furnace to recover such metals, and secondly in the treatment of the residue of the material in order to permit of the reduction and conversion of the iron-sand contained in the material into iron or steel.

No. 29689.—7th June, 1911.—JOHN DUXFIELD McLAREN, of Manawaru, Auckland, New Zealand, Farmer. Improved wire-strainer.*
Extract from Specification.—According to my invention, one of the wires is gripped by passing it through a dog having a jaw in which is an inclined recess to receive the wire, the frictional resistance due to the bending of the wire and the shape of the recess preventing the wire from slipping through it. Two similar dogs pivoted upon wire members project from the other side of the main hand-lever, each of them also grip the second wire in a similar way. The spring members connected to each of these two dogs and to the lever upon which each dog is pivoted alter the angle of the dogs one after the other when the main lever is vibrated so that one dog after the other slides upon the wire and then grips it so that it may be drawn taut. After the straining has been effected a loop is formed in the end of one wire, through which the second wire is passed, and its end coiled.

No. 29776.—24th June, 1911.—EDWARD ARTHUR WILLIAMS, of Kaitoke, New Zealand, Wool-classer. Improvements in the wool-racks of sheep-shearing sheds.*
Claims.—(1.) A wool-bale rack constructed of separate sides, each side being provided with means upon its side edges by which it may be fastened to the adjacent edge of the next side and to make a hinge joint therewith, substantially as specified. (2.) A wool-bale rack constructed of separate sides, each provided with lugs projecting beyond its side edges and formed with eyes in such projections, the lugs of one side being adapted to overlap with those of the others adjacent to it, and rods passed down through the eyes of the overlapping lugs, substantially as specified.
