Notice of Acceptance of Complete Specifications.

Patent Office,
Wellington, 23rd September, 1905.

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. 18399.—3rd September, 1904.—THOMAS FALVEY, of 22, Clyde Quay, Wellington, New Zealand, Engineer. An improved steam-turbine.*

Extract from Specification.—According hereto inclined vanes arranged in concentric circles are fixed to a main revolvable disc, and enter annular spaces formed between concentric circles of vanes fixed to the casing of the turbine and inclined in a direction reverse to the movable vanes. Steam is admitted to the inner circles of fixed vanes, and passing through the outer circles is expanded, and finally exhausted into a condenser or to the atmosphere. Annular partitions forming a disc divide the vanes into two sets or series, the directions of the vanes of one set being the reverse of those of the other set. A valve admits steam to either set as desired for forward or backward motion. The set of vanes used for forward driving is subdivided by other partitions forming a second disc. Steam is admitted to one set of the subdivided vanes when half only of the power of the turbine is required, and when the full power is required steam is admitted to the whole of the subdivided vanes. A valve is provided with ports arranged for admitting the steam as above described. The casing of the turbine surrounds the disc and vanes and conducts the exhaust steam to a valve, valves, or stop-cocks operated simultaneously with the steam-admission valve as required during forward or backward driving. The exhaust valve or valves may be operated by cranks and rods or by the pressure of the exhaust steam, and may be held open by friction springs or counterpoise weights. The main disc has a boss fitting a socket upon the cover of the casing, and a shaft secured in the boss of the main disc has bearings and thrust-blocks. The turbine may be simple or compound, and two or more may be arranged in series, in which case the end thrust of the steam upon the shaft is balanced.

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

No. 18526.—1st October, 1904.—SAMUEL FORD, Sanitary-pipe Maker, and JAMES SPIERS FREEMAN, Land Agent, both of Dannevirke, New Zealand. Improved compound and method of manufacturing the same for the production of railway-sleepers, building-blocks, and other articles.*

Claims.—(1.) For the purpose indicated, an improved compound consisting of boiling tar, pumice, lime, and sulphur in the proportions stated, substantially as set forth. (2.)

A railway-sleeper comprising a casing having bolt-holes and its ends flanged, end plates held in position within the casing by the flanges, bolts for securing the rails passed through the bolt-holes, washer-plates upon the bolts, and a compound of tar, pumice, lime, and sulphur filling the said casing, substantially as set forth.
