Improvements in systems of electrical distribution.*

Claims.—(1.) The method of regulating the electro-motive force supplied to translating devices in the secondary circuit of a transformer by means of a third coil on the transformer, which third coil is connected to one coil of a second transformer, the other coil of which is in the circuit containing the translating devices. (2.) An electrical installation in which for the purpose of varying the electro-motive force in the secondary circuit of a transformer a third coil is provided on the transformer with means for varying its active length, said third coil being connected to one coil of a second transformer, the other coil of which is in the circuit containing the translating devices. (3.) A system of electrical distribution substantially as described with reference to the drawings.

No. 12020.—28th September, 1899.—WILLIAM ERNEST HUGHES, of Queen’s Chambers, Wellington, New Zealand, Patent Agent (nominee of Benjamin Garver Lamme, of 230, Stratford Avenue, Pittsburg, Pennsylvania, United States of America, Electrical Engineer). Improvement in single-phase alternating-current generators.*

Extract from Specification.—“My invention relates to single-phase alternating-current generators, and has for its object to improve the construction of the armature so that the coils thereof can be very easily inserted into their respective slots without bending or the exertion of injurious pressure thereon. For this purpose the slots in the armature-core for the reception of the coils are not made radial, but the sides thereof in each group of coils are made parallel to each other, so that the distance between two slots intended to receive a coil is the same at the bottom of the slots as it is at the top of the slots—that is to say, on the outer periphery of the armature.”

Claim.—A dynamo-electric machine having an armature provided with either a wire winding or a strap winding, and constructed as described, and shown in the drawings.

No. 12029.—29th September, 1899.—JAMES PALMER CAMPBELL, of Wellington, New Zealand, Registered Patent Agent (nominee of Benjamin Garver Lamme, of 230, Stratford Avenue, Pittsburg, Pennsylvania, United States of America, Electrical Engineer, and John Purington Mallett, of 6728, Simen Avenue, Pittsburg aforesaid, Electrical Engineer). Improvements in electrical machines.*

Claims.—(1.) For an electrical machine, a continuous multipolar winding, in which one or more middle conductors of each phase and pole-group are connected at its respective ends to the nearest side conductor of the same phase, for the purpose specified. (2.) For an electrical machine, a multipolar polyphase bar-winding, in which the middle or adjacent-to-the-middle bars for the several phases of each pole are alternately long and short, the remaining bars being of intermediate length. (3.) For an electrical machine, a distributed continuous winding, comprising bars of three different lengths and end-connectors, all of which are of substantially the same length and form, and symmetrically arranged. (4.) For electrical machines, armatures or primary members constructed substantially as described with reference to the drawings.
(Specification, 5s. 3d.; drawings, 8s.)

No. 12121.—27th October, 1899.—DANIEL MUNSON SEATON, of 24, Montgomery Street, San Francisco, United States of America, Lawyer. Improvements in looms.

My invention is an improvement on the loom disclosed by me in an application for Letters Patent of New Zealand, No. 10512, dated 14th April, 1898, and relates particularly to means for feeding at will threads of different colours to the weft-thread carrier, so as to make a fabric of any desired pattern or of any desired combination of coloured threads. In the loom referred to, the weft-threads are laid in the fabric hair-pin fashion, with the loops alternating at the opposite edges thereof, to form the selvage, and these loop-lengths are measured and cut from the supply-thread, and are fed to the weft-thread carrier by a reciprocating feeder, which presents first one end of the loop-length to the weft-thread carrier, and then the other. My present invention relates particularly to feeding-mechanism whereby different-coloured loop-lengths may be supplied to the weft-thread carrier.
[NOTE.—The number and length of the claims in this case preclude them from being printed, and the foregoing general description is inserted instead.]

No. 12175.—11th November, 1899.—HUGH LAING MAINLAND, of Burke’s, New Zealand, Mechanical Engineer. Improvements in traps for catching animals.

Claims.—(1.) In the springing platform of any spring-jaw trap, such as claimed by my Patent No. 7800, the improved method of hinging the two plates forming the spring platform by strips partly cut out of openings in one plate, such as C¹, C², or C⁷, working in holes cut out of the other plate such as C³, instead of the hinge-pin there shown and claimed, substantially as set forth and for the purposes indicated. (2.) The method of forming one of the springs into a combined lifting-spring, tug-spring, and a swivel with the tethering-chain, substantially as set forth and for the purposes specified.
(Specification, 1s. 9d.; drawings, 3s.)

No. 12182.—15th November, 1899.—JOHN ALEXANDER MCPHEE, of Harbour Terrace, Dunedin, New Zealand, Clay-pipe Maker. An improved can-opener.

Claims.—(1.) A can-opener consisting of a handle having a centre pin C and adjustable cutter D moving in slot H, K, and secured in position by plain or wing nut or other suitable means. (2.) The combination with any form of can-opener of the centre pin C and movable cutter D, and secured as described to form an improved can-opener.

No. 12239.—14th December, 1899.—JOHN COWAN and the STIRLING BOILER COMPANY, LIMITED, of 2, St. Andrew’s Square, Edinburgh, Scotland, Manufacturers. Improvements in water-tube boilers.
