No. 20697.—12th February, 1906.—ANDREW JACK, of Palmerston North, New Zealand, Plumber. An improved gas-burner.

Claim.—A gas-burner comprising a solid body portion formed with an annular recess within it, and with a ring of small apertures leading upwards from the recess through the body, in combination with a socket portion into which the body fits or to which it is connected, formed with gas-passages leading to the bottom of the annular recess, substantially as and for the purposes specified.

No. 20712.—14th February, 1906.—GEORGE RIDGWAY, of the Great Boulder Gold-mine, near Kalgoorlie, Western Australia, Australia, Engineer. An atmospheric filter.

Extracts from Specification.—For the purpose of my invention I make a hollow spindle, consisting of a number of compartments. At the end of the spindle I make a compartment A, which consists of a plunger-casing having a number of pipe connection-hubs B, and in this I fit a plunger C operated by a crank and connecting-rod, or by similar suitable means. I may fit one or more sniffing-valves to this plunger-casing to admit air, or I may admit compressed air from a receiver or such similar source of supply. . . . Lower down the spindle I make another compartment D, also having a similar number of pipe connecting-hubs E. This compartment D is connected to a vacuum chamber or vacuum pump by means of an internal pipe or passage F and the stationary chamber G. I now make a third compartment H, also having a similar number of pipe connecting-hubs K. This compartment H is connected to a separate vacuum chamber or pump, or to the same vacuum chamber having separate compartments, or such means as will enable the solutions to be kept separate, if desired, by the passage surrounding the aforesaid internal pipe and a second stationary chamber L. . . . I make angle-iron rings U1 to which I attach bearings V1 supporting the gudgeons P1 and Q1. On the end of the gudgeons P1 I place a pinion or finger wheel W1, which is adjusted to engage in a rack X1 at the position where it is required to turn the tray over. This rack is just long enough to make the tray take one complete revolution. I may attach a light spring catch or the like to engage with edge of the tray, to normally hold it in a horizontal position. For this process the pulp and wash solutions and water are introduced direct to these trays by pipes F1, and automatically controlled valves or cocks, which can be operated by means of the passing trays.
[NOTE.—The above extracts from the specification are inserted in place of the claims.]

No. 20713.—14th February, 1906.—JAMES PALMER CAMPBELL, of No. 15 Featherston Street, Wellington, New Zealand, Solicitor (nominee of RUDOLF BRAUN, of Westinghouse Works, Trafford Park, Manchester, England, Electrical Engineer). Improvements relating to systems of electrical distribution.

Claims.—(1.) A load-equaliser for an alternating-current-supply circuit, comprising a rotary converter the alternating-current winding of which is connected across the circuit at a point intermediate the power-station and the point of supply, the direct-current brushes of the said converter being connected to the brushes of a shunt-wound direct-current machine the rotor of which is provided with a fly-wheel, and means whereby either the resistance in the field winding of the said machine or the voltage impressed on the said winding may be varied either manually or automatically in accordance with the load on the supply circuit, substantially as and for the purpose specified. (2.) In a load-equaliser of the kind described, a rotary converter having shunt and series field windings so connected that when the converter is operating to transform from alternating current to direct current the field excitation produced by the shunt and series windings may oppose one another, substantially as and for the purpose specified. (3.) In an equaliser of the kind described, means for varying the resistance in the shunt field winding of the direct-current machine according to the load on the supply circuit, comprising a liquid rheostat having a fixed electrode and a movable electrode, the movable electrode being mounted on the shaft of an alternating-current motor the primary winding of which is connected either directly or indirectly to the supply circuit, the said shaft being prevented from completely rotating by a spring, substantially as and for the purpose specified. (4.) In an equaliser of the kind described, means for varying the voltage impressed on the terminals of the shunt field winding of the direct-current machine, comprising a rectifying-device the alternating-current terminals of which are connected to a series-transformer in the supply circuit, the direct-current terminals of the said device being connected in series with the said field magnet winding, substantially as described. (5.) The modification of the invention in which an adjustable rheostat is connected in series with the field magnet winding of the direct-current machine, the said rheostat being automatically operated by a speed-actuated governor to decrease the field excitation of the said machine with an increase of speed, substantially as described.

No. 20717.—14th February, 1906.—LEON SERPOLLET, of 9 and 11 Rue Stendhal, Paris, France, Civil Engineer. Improvements in or relating to steam automobiles.

Claims.—(1.) A steam automobile with instantaneous steam-generator heated by petrol burners in which a special small motor or “feed-engine” controls simultaneously the pump which forces the water to the generator and the pump which forces the petrol to the burners, while at the same time producing a draught of air to the burners in proportion to the quantity of petrol injected, the exhaust steam passing to a blast-pipe located in the chimney of the boiler, where it produces an artificial draught, in combination with a steam-supply regulator, enabling by a single operation the steam to be supplied either to the small feed-motor alone or simultaneously to the feed-motor and to the principal motor of the automobile, or the supply of steam to the feed-motor and to the principal motor to be stopped, and in combination with a feed-water heater into which are led simultaneously for circulation in contrary directions in contact with the metallic walls which separate the same the exhaust steam from the principal motor on its way to the condenser and the feed-water on its way to the boiler, substantially as described. (2.) In a steam automobile according to claim 1, the arrangement on the steam-pipe which leads from the regulator to the feed-engine of a lever operated by the driver, and which permits of throttling said tube more or less, so as to regulate the area of admission to the feed-engine, and thereby to regulate the feed and thereby the speed of the vehicle. (3.) In a steam automobile according to claim 1, the use of a feed-water heater comprising several coupled elements, each formed of a tubular body and a group of small tubes passed through said tubular body, the water which passes to the boiler circulating in the small tubes and the exhaust steam from the principal motor which passes to the condenser circulating in the tubular body around the small tubes in the direction contrary to that of the water, substantially as described. (4.) In a steam automobile according to claim 1, the arrangement on the steam-pipe which leads from the boiler of a regulator comprising a plane-surface plate in which are bored three small orifices 1, 2, 3 leading into the pipe f which connects to the feed-engine, and a larger orifice 4 leading into a pipe g which connects to the principal motor, in combination with the circular slides t and t¹ carried by a lever g, and which move over the plate in the interior of the steam-inlet chamber so as to close all the orifices, or to open either the orifice 1 alone, or simultaneously the orifices 1, 2, and 4, or the orifices 1, 2, 3, and 4, substantially as described.
