No. 27837.—18th June, 1910.—ARTHUR HENRY HALE, of 27 Taonui Street, Palmerston North, New Zealand, Inventor, and FREDERICK JOSEPH NATHAN, of Broad Street, Palmerston North aforesaid, Inventor. A hot-water circulator for general use heated by waste gases from exhaust-pipe connected with petrol and gas engines.

Extract from Specification.—According to our invention, the exhaust-pipe from the engine passes through the middle of a heater-cylinder, and a water-pipe from the cooling-water system of the engine is led through the exhaust-pipe and into the heater-cylinder. The heated water is withdrawn through a pipe at the opposite end of the heater-cylinder. A branch pipe from a cold-water supply is connected to the said water-pipe before it enters the heater-cylinder, so that cold water may be added to the water coming from the engine, or the water from the engine entirely dispensed with.

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

(Specification, 3s. 3d.)

No. 27877.—9th June, 1910.—CHARLES BOWTELL SMITH, of Crawford Street, Dunedin, New Zealand, Master Printer. Improved counter-sales check-book.

Claims.—(1.) In a counter-sales check-book, in combination with same, a distinguishing letter-number on each invoice and its duplicate, as well as the page-number on each, all substantially as shown on the drawing and as described and explained. (2.) A distinguishing mark, letter, or number, or combination of these, as well as the number of each page, to be printed on each invoice-page and its duplicate, all substantially as set forth.

(Specification, 3s. 6d.)

No. 27917.—28th June, 1909.—HUBERT PEARCE, of 3 Oakhall Road, Wanstead, Essex, England, Engineer, and WILLIAM BARRATT, of 6 Thirlmere Road, Muswell Hill, Middlesex, England, Engineer. Improvements in and in apparatus for aerating liquids.

[NOTE.—This is an application under section 98 of the Act, the date given being the official date of the application in Great Britain.]

Claims.—(1.) The process described for aerating liquids, which consists in admitting the aerating gas to the underside of a baffle-plate having minute perforations therein, and arranged beneath an aerating-chamber formed of or containing an open-ended tube or tubes or compartments, to hold the liquid to be aerated, each tube or compartment being of considerable height relatively to its diameter and opening above into a gas-chamber of approximately the same capacity as that of the tube, tubes, or compartments, and having a pressure-release snifting-device, substantially as described and for the purposes stated.

[NOTE.—Here follow three other claims.]

(Specification, 8s. 6d.)

No. 27942.—21st June, 1910.—P. AND D. DUNCAN, LIMITED, of Christchurch, New Zealand, Agricultural Engineers. An improved flexible harrow.

Claims.—(1.) A flexible harrow comprising sections, shackles secured to the rear of the sections, and hooks secured to the front of the sections by teeth passing through the sections, shackles, and hooks, and fastened by nuts, as set forth. (2.) In a flexible harrow composed of sections and links, each section and link having legs of different lengths, and teeth secured to the sections in the positions described, as set forth. (3.) In a flexible harrow, the employment of hooks upon the front of the sections and engaging the links, as set forth.

[NOTE.—Here follow four other claims.]

(Specification, 3s. 6d.)

No. 27954.—22nd June, 1910.—NATIONAL CAR ADVERTISING COMPANY, a corporation duly organized under the laws of Delaware, with offices at 115 Adams Street, Chicago, Cook, Illinois, United States of America (assignees of Marselius Thurston Ash, Engineer, of 115 Adams Street, Chicago, Cook, Illinois, United States of America). Display or advertising devices.

Claims.—(1.) In combination, a plurality of frames, vertically adjustable members on said frames, a track for supporting said frames, and a carrier connected to said members for moving said frames along said track. (2.) In combination, a plurality of frames, vertically adjustable rods on said frames, a track for supporting said frames, and a flexible carrier connected to the lower ends of said rods for moving said frames along said track. (3.) In combination, a plurality of frames, vertically adjustable rods mounted on said frames, a track for supporting said frames, and a flexible chain secured to the lower ends of said rods moving said frames along said track, said rods forming pivots between certain of the links of the chain.

[NOTE.—Here follow fifteen other claims.]

(Specification, 13s. 6d.)

No. 28011.—30th June, 1910.—HARRY WALTON BLAND and JAMES YOUNG, of 281 Collins Street, Melbourne, Victoria, Australia, Commission Agents. Improvements in self-heating burning-off and brazing tools and the like.

Claims.—(1.) In self-heating burning-off and brazing tools and the like, a liquid-fuel reservoir having a burner attached thereto, one or more flat chambers interposed between said reservoir and burner, and tubes connected to said chamber or chambers and arranged to communicate with said reservoir and burner, substantially as described.

[NOTE.—Here follow seven other claims.]

(Specification, 8s.)

No. 28038.—6th December, 1909.—RALPH FALKINER, Pastoralist, and PAUL BOLL, Electrical Engineer, both of 175 William Street, Melbourne, Victoria, Australia. Improved mechanism for portable shearing or clipping machines.

[NOTE.—This is an application under section 98 of the Act, the date given being the official date of the application in Australia.]

Extract from Specification.—Comprises a petrol or other internal-combustion engine mounted in a rectangular framework, the corners of which project upwardly and outwardly and are fitted with bearings to carry correspondingly inclined spindles, the lower ends of which are fitted with conical friction pinions, whilst the upper ends are fitted with a universal joint to communicate motion to another shaft or spindle depending therefrom and adapted to convey motion to the handpiece through another universal joint.

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

No. 28081.—15th July, 1910.—HUTCHINSON’S SCALES COMPANY, LIMITED, a company duly incorporated under the Companies Act of New Zealand, and having its registered office at Hereford Street, Christchurch, in the Provincial District of Canterbury, in the Dominion of New Zealand (assignees of George Hutchinson, of Christchurch, Engineer). Improvements in scales.

Extract from Specification.—This invention relates to dial scales of that class in which the load to be weighed and a constant resistance weight each exert a torque upon a horizontal spindle, the ratio of the forces thus exerted altering for different angles of rotation of the spindle, whereby equilibrium is obtained at different angles of rotation of the spindle between a diversity of loads and the resistance weight, a pointer either directly or indirectly actuated by the spindle indicating upon a dial by its angular positions the weight of each load. In scales of this class hitherto known, the resistance weight has been a heavy arm rigidly fixed to the spindle and tending to hang below it, and mechanism has caused a diversity of loads to be weighed to deflect the heavy arm in greater or less degree, according to their mass. In some of the scales just described, equal spacing has been attained—that is to say, each repeated addition of a given weight has caused the pointer to move through the same angular distance as was caused by preceding such additional weight, throughout the range of the dial, by fixing a cam upon the spindle and by causing the load to be weighed to pull upon a strap, the strap winding and unwinding upon the face of the cam rotates the cam and spindle, and consequently deflects the heavy arm, the cam being specially shaped to correct tendencies to uneven spacing by presenting to the strap different radii or offset distances, and consequently increasing or decreasing the torque of the strap, for different angular positions of the cam. Following upon my previous New Zealand patents, Nos. 24588 and 26223, the above principle is shown applied more widely to scales of various forms and for various commercial purposes. The
