Oct. 27.] THE NEW ZEALAND GAZETTE. 2523

No. 18501.—28th September, 1904.—FREDERICK WILLIAM GASMIER, of 2, Victoria Street, Petersburg, South Australia, Australia, Engine-driver. Improved method of and means for enabling a brake to be applied or retracted from either side of a railway vehicle.

Claims.—(1.) In a brake mechanism for railway vehicles, the combination with a brake-lever of a movable catch to support the brake-lever, a rock-shaft connected to the movable catch, and draw-rods for operating such rock-shaft from either side of the vehicle, substantially as described and for the purpose set forth. (2.) In a brake mechanism for railway vehicles, the combination with a brake-lever of a movable catch to support the brake-lever, a rock-shaft supported from the vehicle-frame and connected to the movable catch and provided with draw-rods whereby it may be operated from either side of the vehicle, substantially as described and for the purpose set forth. (3.) In a brake mechanism for railway vehicles, the combination with a rockable brake-shaft of two brake-levers, two movable catches to support the brake-levers, a rock shaft supported from the vehicle-frame and connected to the movable catches and provided with draw rods whereby it may be operated from either side of the vehicle, substantially as described and for the purpose set forth.

No. 18503.—28th September, 1904.—WILLIS RODNEY WHITNEY, of Schenectady, New York, United States of America, Chemist and Electrical Engineer. Filaments and method of manufacturing the same.

Claims.—(1.) The method which consists in heating or firing a flashed filament to a sufficient temperature and for a sufficient length of time to produce as a new product of manufacture a filament the resistance of which with increase in temperature becomes greater than its cold resistance. (2.) The method which consists in heating an ordinary untreated or unflashed carbon filament to a high temperature sufficient to drive out mineral, gaseous, or other impurities, then flashing the filament, and then firing the flashed filament to a sufficient degree to change the molecular structure of the flashed coating. (3.) The method of forming a carbonaceous product suitable for filaments which consists in heating or firing a decomposed hydrocarbon in a non oxidizing atmosphere at a sufficiently high temperature so that after such heating or firing the minimum resistance of the resulting product, with indefinite increase of temperature, forms a higher percentage of its cold resistance than does the minimum resistance of the unfired substance with increase of temperature, as compared with the cold resistance of the said unfired substance. (4.) As a new article of manufacture, a carbonaceous filament which when heated above atmospheric temperature never drops to as low a percentage of the resistance at ordinary atmospheric temperature as other forms of carbon, and may have a higher resistance than when at ordinary atmospheric temperature. (5.) As a new article of manufacture, a carbonaceous filament which has a higher resistance when hot than when at ordinary atmospheric temperature. (6.) A new form of carbon suitable for filaments which is tough and flexible, of low specific resistance, and which when heated above atmospheric temperature never drops to as low a percentage of the resistance at ordinary atmospheric temperature as other forms of carbon, and may have a higher resistance than when at ordinary atmospheric temperatures. (7.) A form of carbon suitable for filaments which has a greater resistance when hot than when at ordinary atmospheric temperature.
(Specification, 12s.)

No. 18504.—28th September, 1904.—WILLIAM EDWARD HAMILTON, of Zanesville, Musikingum, Ohio, United States of America, Salesman. Mining-machines.

Extract from Specification.—Briefly describing the operation of the machine, an undercut is made at the level of the floor of the mine-chamber by the undercutting mechanism. The undercut being made, the undercutting mechanism is removed and the dislodging mechanism is mounted on, and the loading mechanism is connected to, the radial frame. An overcut is made, the breaking-levers at the same time breaking down the section between the undercut and the overcut, and the material broken down is caught by the loading mechanism and conveyed to the car. This horizontal section of the wall being removed, the mechanisms are elevated into position to make a second overcut, and this second section is removed in the same manner as the first. This operation is repeated until the wall of the chamber is entirely removed up to the top. Then the machine is moved forward, a second undercut is made, and a second vertical section of the wall or vein is removed in the same manner as the first.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 18505.—28th September, 1904.—OTTO GEMEINHARDT, of Swamp Road, Footscray, Victoria, Australia, Merchant. An improved machine for measuring out and wringing skins or like articles.

Claims.—(1.) In an improved machine for measuring out and wringing skins or like articles, standards, bearings attached to said standards, an axle rotating in said bearings, a measuring-roller and a grooved pulley upon said axle, a crank-handle at one end of the said axle and at the other a worm, said worm turning a worm-wheel rotating a pointer in front of a dial, all as and for the purposes described, and as illustrated in the drawings. (2.) In an improved machine for measuring out and wringing skins or like articles, a measuring-roller, a grooved pulley turning with said roller, a grooved pulley behind said roller driven by a belt, a skeleton wheel driven by said grooved pulley, a holder behind said skeleton wheel, all as and for the purposes described, and as illustrated in the drawings. (3.) In an improved machine for measuring out and wringing skins or like articles, a measuring-roller in combination with which is a wringing-roller, said wringing-roller being adjustable in its relation with the said measuring-roller, all as and for the purposes described, and as illustrated in the drawings. (4.) An improved machine for measuring out and wringing skins or like articles, consisting of a measuring-roller rotated by hand or power, said measuring-roller frictionally rotating a wringing-roller adjustably adjacent thereto, a skeleton wheel rotated by a belt turning with the said measuring-wheel, a worm-wheel on the axle of the measuring-roller turning a worm which turns a pointer in front of a dial, said worm-wheel having a striker thereon engaging with striker on an intermediately pivoted lever, said lever having a hammer thereon which strikes a gong, all as and for the purposes described, and as illustrated in the drawings.

No. 18506.—28th September, 1904.—HERMAN CHARLES WOLTERECK, of 3, Edinburgh Mansions, Howick Place, Victoria Street, London, S.W., England, Consulting Chemist. Process of producing ammonia.

Claims.—(1.) The process of producing ammonia consisting in passing air and steam over peat heated to a temperature below 550° C. (2.) The process of producing ammonia consisting in passing a mixture of superheated steam and air over peat at a temperature not exceeding 550° C, and preferably within the range of 350° C to 450° C. (3.) In the process of producing ammonia from peat, the method of maintaining the temperature of reaction by regulating the steam-supply.
(Specification, 3s.)

No. 18567.—7th October, 1904.—HENRY READ, of “Awamoa,” Alma, Oamaru, New Zealand, Farmer. An improved adjustable rail-bed plate.

Claims.—(1.) In rail-bed plates, the making of the bolt-holes one a little inwards and the other a little outwards, so that on reversing the plate the position of B, and consequently of the rail, is altered to the extent of the deviation of the said holes from the centre, all substantially as shown and described and explained. (2.) In rail-bed plates, in combination, the bolt-holes made one a little inwards and the other a little outwards of the centre of the length of the said plate, with a thinning of the thickest part or flange of the plate to allow for its being level with the thinner part of the rail-flange, all substantially as shown on the drawing, and as described and explained.
