Notice of Acceptance of Complete Specifications.

Patent Office,
Wellington, 22nd March, 1911.

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.

The copies of claims and extracts from the specifications and drawings are merely intended to give some further indication of the invention than is disclosed in the title, and the complete specifications and drawings should be referred to for a description of the invention.

No. 27421.—9th March, 1910.—ARTHUR GRETTON TOMKIES, of Orowaiti Road, Westport, New Zealand, Engineering Instructor, Westport Technical School. Improvements in apparatus for cutting corrugated and other metal sheets.*

Claims.—(1.) In apparatus for cutting corrugated and other metal sheets of the class herein described, a pair of sleeves mounted to rotate or slide longitudinally within bearings formed in the sliding-frame and each formed with a bore extending eccentrically through it, spindles on the cutting-discs journaled to rotate within the respective bores, and means for holding the sleeves from movement, substantially as and for the purposes specified. (2.) The improvements in apparatus for cutting corrugated and other metal sheets substantially as described and explained, as illustrated in the drawings, and for the several purposes set forth.

(Specification, 3s. 6d.)

No. 27607.—21st April, 1910.—THOMAS HILL EASTERFIELD, of 18 Talavera Terrace, Wellington, New Zealand, Professor, and CLARA MILLICENT TAYLOR, of 38 Kelburne Parade, Wellington aforesaid, Research Student. A process for the preparation of ketones.*

Extract from Specification.—The commonest process for preparing ketones consists of heating the calcium, barium, or lead salts of organic acids to a high temperature. We find that in the case of the higher fatty acids, such as palmitic, stearic, brassidic, oleic, cerotic, montanic, and melissic acids, a much better process is to heat the acid in contact with cast-iron turnings, taking care that the temperature does not far exceed the temperature of incipient decomposition of the acid. The heating is continued until the evolution of carbon-dioxide has nearly ceased, and the crude product is purified by any of the usual methods for the purification of ketones, such as crystallization from a suitable solvent or distillation in a partial vacuum.

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

(Specification, 2s. 3d.)

No. 27673.—4th May, 1910.—CHARLES SUTTIE, of Waharoa, New Zealand, Flax-miller, and MONTAGUE HARRISON WYN-YARD, of Auckland, New Zealand, Solicitor. Improvements relating to mechanical flax-catchers.*

Claims.—(1.) In a mechanical flax-catcher, means of operating the “trip” or release which starts or puts in gear the operating part of the catcher, consisting of a wheel, or segment of a wheel, with or without teeth, or partly with and partly without teeth, located in, or having a segment thereof protruding through a slot into, the feed-mouthpiece of a stripper, and, if desired, tensioned so that when the pressure thereon is relieved it will come back to its original position or continue on until it has made a complete revolution, and connected with or operating by communicated contact the “trip” or release, substantially as and for the purposes described. (2.) In a mechanical flax-catcher, means for the purpose aforesaid, consisting of a flap located in or protruding through a slot into the feed-mouthpiece of a stripper, and tensioned so that when the pressure thereon is relieved it will return to its original position, and connected with or operating by communicated contact the “trip” or release, substantially as and for the purposes described.

[NOTE.—Here follow three other claims.]
