Notice of Acceptance of Complete Specifications.

Patent Office,
Wellington, 10th October, 1899.

COMPLETE specifications relating to the under-mentioned 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. 11690.—8th June, 1899.—NORMAN ROWE, of 1215, Wood Street, Wilkinsburg, Pennsylvania, United States of America, Electrical Engineer. Improvements relating to the regulation of electro-motive force.*

My invention relates to the regulation of electro-motive force, and in particular to the regulation of the electro-motive force supplied by the secondary coil of a stationary transformer the primary coil of which is supplied with alternating currents. The object of my invention is to provide for increasing or decreasing the work-circuit electro-motive force gradually over any desired range without undue expense and complication as regards either the structure or operation of the apparatus employed. In carrying out my invention I divide one of the coils of the transformer into sections which can be cut in or out in succession, and at the same time I vary the electro-motive force by means of a magnetic regulator which operates separately for every action. In this way, before a section is cut in or cut out the electro-motive force is adjusted by means of the inductive regulator, so as to approximate to the new electro-motive force existing after the section has been cut in or out.

Claims.—(1.) For varying the electro-motive force supplied by a transformer, a switch the movement of the arm of which varies the active length of one of the transformer-windings, and at the same time varies an inductive regulator, for the purpose specified. (2.) A switch constructed and operating substantially as described.

No. 11765.—3rd July, 1899.—ALFRED JACOB STERNE, of 253, Broadway, New York, United States of America, Inventor. An improved igniting-device for gas-burners.

Claims.—(1.) An automatic lighter for a gas-burner consisting of an igniting-body, a thermostat, and means whereby the thermostat causes the igniting-body to move to and from the gas-jet, substantially as described. (2.) An automatic lighter for a gas-burner consisting of an igniting-body, a movable support to carry the igniter to and from a position close to the jet-orifice, a thermostat, and means whereby the thermostat actuates said igniter-support. (3.) An automatic lighter for a gas-burner consisting of an igniting-body, a thermostatic bar arranged to cross the flame near the jet-orifice, and means whereby the contraction and expansion of the thermostatic bar moves the igniter respectively to and from the jet. (4.) An automatic lighter for a gas-burner consisting of an igniting-body containing finely divided platinum, a plurality of fine wires laid on said body, a thermostat, and means whereby the thermostat moves said platinised body and wires to and from the jet. (5.) An automatic lighter for a gas-burner consisting of an igniting-body, a pivoted lever to carry the igniting-body to and from the gas-jet, a thermostat, and a positive actuating connection in both directions of motion between the thermostat and the lever carrying the igniting-body. (6.) In an automatic lighter for a gas-burner, the thin thermostatic bar crossing the jet, and turned in the jet edgewise toward the jet-orifice. (7.) An automatic lighter for a gas-burner consisting of an igniting-body and its movable support, a thermostat, and an intermediate lever connecting the thermostat with the support of the igniting-body, whereby the igniting-body is moved an ample distance from the flame.

No. 11875.—9th August, 1899.—P. AND D. DUNCAN (LIMITED), of Tuam Street, Christchurch, New Zealand, Engineers. Improvements in manure-discharge for agricultural drills and sowers.

Claim.—In any drill or sower having for a manure-discharge a bowl rotating horizontally on a bracket below the hopper, arched arms connecting the bowl to the boss as and for the purposes explained, and illustrated in the drawings.
(Specification, 1s. 6d.; drawings, 6s.)

No. 11942.—29th August, 1899.—ALBERT POTTER, of Belle Vue Road, Mount Eden, Auckland, New Zealand, Settler, An improved mustard-cup.
