Notice of Acceptance of Complete Specifications.

Patent Office,
Wellington, 7th April, 1909.

COMPLETE specifications relating to the undermentioned applications for Letters Patent have been accepted, and are open to public inspection at this office. Any person may, at any time within two months from the date of this Gazette, give me notice in writing of opposition to the grant of any such patent. Such notice must set forth the particular grounds of objection, and be in duplicate. A fee of 10s. is payable thereon.

No. 24165.—24th March, 1908.—JAMES MICHAEL DOWD, of Putaruru, Auckland, New Zealand, Farmer. Improvements in ploughs.*

Claims.—(1.) In ploughs, a wheel arranged upon the opposite side of the frame to that upon which the land-wheel is placed, and in a position between the steering-wheel and back wheel, in combination with means whereby such wheel may be raised or lowered in relation to the frame, substantially as and for the purposes specified. (2.) In ploughs, a wheel arranged upon the opposite side of the frame to that upon which the land-wheel is placed, and in a position between the steering-wheel and back wheel, in combination with a crank-shaft journalled in the frame and upon which the wheel is mounted, a hand-lever for turning such crank-shaft, and means for locking it at any position, substantially as and for the purposes specified.

No. 24190.—28th March, 1908.—JOHN ERNEST LELLIOTT CULL, of 65 Dean Street, Christchurch, New Zealand, Engineer. Improved electrical process for the manufacture of iron, steel, and other metals from their ores.*

Extract from Specification.—The metallic oxides in a pulverised condition are fed in a continuous stream into a chamber, which I call the reducing-chamber, simultaneously with powdered carbonaceous material, such as coal-coke or charcoal, and hot air. The proportion of air to fuel is such that the resulting flame is highly reducing towards the metallic oxides which are fed in. The oxides, fuel, and air, and any necessary fluxing-material, are fed in preferably at the top of the chamber. The oxides being in a pulverised state are quickly heated, and collect in the lower end of the chamber as a highly heated mass. The top of this mass being subjected all the time to the action of the reducing-flame due to the interaction of the fuel and hot air, the oxides are partially or completely reduced to the metallic condition. If desired, this mass may be made to contain a proportion of solid carbon or carburizing-material. This may be done in any convenient way—as, for example, by making the powdered fuel to consist of particles of different sizes, the larger of which will collect in the mass, or by introducing small pieces of highly carburized metal with the fuel. The mass passes from the reducing-chamber to the electric melting-hearth, where the smelting is completed. The molten metal is tapped from this hearth, and any suitable type of electric hearth may be used.

No. 24259.—11th April, 1908.—MARK SAUNDERS, of Timaru, New Zealand, Ironworker. Means for obtaining power from the action of the sea.*

Extract from Specification.—A pipe, or a number of pipes, each tapering towards one end, is arranged with their larger ends so disposed as to be mainly below the level of the water. These pipes are then inclined upwards to their back end, and are made to extend in a direction corresponding to the direction of movement of the waves, so that such waves in their motion will pass up into such pipes. As each wave passes into the mouth of the pipe it will imprison the air within such pipe, and compress and drive it up the pipe and into a compressed-air tank connected with the pipe. At the same time this water will be delivered from the back end of the pipe into a trough or flume arranged to receive it, and by such flume be conveyed by gravity to operate a Pelton or other motor. Suitable valves will be provided for preventing any backflow of compressed air or water. The pipes will be so disposed that their mouths may be raised or lowered at will, so that they may be adjusted to the varying heights caused by the rise and fall of the tide.

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