———

Claims.—(1.) A device for transforming electrical energy into red-heat energy wherein the enclosure or support (for containing or supporting the resistance) is made of quartz, or equivalent substance as defined, whereby very high temperatures (as, for example, 1,000° C. or more) may be obtained, substantially as and for the purposes described. (2.) A device for transforming electrical energy into red-heat energy in accordance with claim 1, wherein the resistance and the said enclosure or support therefor are in surface contact with one another at the working temperature. (3.) A device for transforming electric energy into red-heat energy in accordance with claim 1 or claim 2 hereof, wherein the resistance is covered or [and] supported by an enclosure or support of minimum weight which does not exceed 0·15 grammes per watt and advantageously does not exceed 0·025 grammes per watt. (4.) A device for transforming electric energy into red-heat energy in accordance with claim 1 or claim 2 or claim 3 hereof, wherein the total weight of the resistance and enclosure or support covering or [and] supporting said resistance does not exceed 0·225 grammes per watt and advantageously does not exceed 0·05 grammes per watt. (5.) In a device for transforming electrical energy into red-heat energy, the combination with an enclosure, in accordance with any of the foregoing claims, of a removable resistance arranged to fit closely or approximately the interior of said enclosure, substantially as and for the purposes described. (6.) In a device for transforming electrical energy into red-heat energy, the combination with a resistance as specified of a tube of the shortest possible length closely or approximately fitting over the resistance, said tube being of a bore not exceeding three-sixteenths of an inch internal diameter, all substantially as and for the purposes described. (7.) A device for transforming electric energy into red-heat energy comprising a resistance of a suitable material arranged in or on an enclosure or support in accordance with claim 1, the whole being devised in such a way that on the passage of the electric current as large a proportion as possible of the electric energy is converted into heat between the lines A and D on the spectrum, and that the working equilibrium is attained in as short a time as possible. (8.) A stove for warming or cooking purposes provided with an electrical heating-device constructed in accordance with any of the foregoing claims, substantially as described.

No. 26647.—28th September, 1909.—JAMES THOMAS HUNTER, of 157 Featherston Street, Wellington, New Zealand, Patent Agent (nominee of Robert French Thompson, of 88 Cromwell Road, Wimbledon, Surrey, England, Engineer). Improvements in and connected with the smoke-boxes of boilers of the locomotive type.

———

Claims.—(1.) A smoke-box of a locomotive-boiler provided with a V-shaped pivoted deflector situated behind the blast-pipe and in front of the smoke-box tube-plate, and a series of baffle-plates arranged in front of the blast-pipe and in the vicinity of the smoke-box door. (2.) In a smoke-box of the kind described, the employment of a pivoted V-shaped deflector behind the blast-pipe, and having deflecting-wings adapted to throw down any live cinders which may strike them. . . .

[NOTE.—Here follow nine other claims.]

No. 26648.—28th September, 1909.—FRIEDRICH CARL WILHELM TIMM, of Hamburg, Wandsbeckerchaussee 86, Germany, Engineer. Process and apparatus for the production of metals.

———

Claims.—(1.) Process for the production of metals, especially such as are easily volatilised, by conducting the smelted raw material through a furnace filled with red-hot pieces of fuel, characterized by heat being alternately abstracted from the column of red-hot pieces of fuel by the fluid mass trickling through the same with reduction of the metal, and added to the fuel by a supply of air, the fluid raw material being cut off while the air is being supplied. (2.) A method of carrying out the process specified in claim 1, characterized by the gases of the blowing period, with a further supply of air, being utilised for melting down raw material consisting of small pieces in a reverberatory furnace. (3.) Apparatus for carrying out the process specified in claims 1 and 2, characterized by several similar furnaces communicating alternately with each other in such a manner that the gases produced by blowing in one furnace, together with a further supply of air, are used to melt down raw material in another furnace having a reducing-space situated below the melting-space. (4.) Apparatus for carrying out the process specified in claims 1 and 2, characterized by the fact that an outlet-pipe is arranged in the interior of the furnace for carrying off the gases formed during the blowing period, and that the apertures for the supply of the air producing the heat required for smelting are situated above those for blowing. (5.) Methods of and means for production of metals, substantially as described, and as illustrated by the drawings.

No. 26650.—1st October, 1908.—STEPHEN JOHN PHILLIPS, of Glencoe West, South Australia, Railway Ganger. An improved cutting and cauterizing device.

[NOTE.—This is an application under the International and Inter-colonial Arrangements, the date given being the official date of the application in Australia.]

———

Claims.—(1.) An improved cutting and cauterizing device comprising a movable cutter or knife to which heat is continuously applied, arranged within a framing working against and automatically returned with a return spring. (2.) In a cutting and cauterizing device, the combination of a movable cutter or knife to which heat is continuously applied, and a bed-plate or cutting-block suitably supported one above the other in such manner that upon each depression the cutting-edge of the cutter or knife may engage the bed-plate or cutting-block, to be automatically and expeditiously returned by a suitable return spring, substantially as described. (3.) In a cutting and cauterizing device, the combination with a movable cutter or knife (such as A) having an inside bevelled cutting-edge (such as A’) of an operating lever or handle (such as B) pivotally connected within a supporting framing (such as C) having a return spring (such as D), substantially as described and for the purposes indicated.

No. 26651.—28th September, 1909.—The Honourable CHARLES ALGERNON PARSONS, of Heaton Works, Newcastle-on-Tyne, Northumberland, England, Engineer. Improvements relating to turbines.

———

Extract from Specification.—This invention relates to improvements in partial-admission turbines of the type in which there is provided in front of each ring of rotating blades a segment of guide-blades in which a drop of pressure occurs, and the turbine is divided into separate elements, each comprising a bladed drum working within a separate chamber in which only a small drop in the pressure of the working-fluid is allowed. The object of the invention is to reduce the length of such turbines and to avoid the skin-friction and losses by spilling of the working-fluid from the steam-passage into the chambers which occur in such turbines. The first part of this invention consists in a partial-admission turbine of the type above referred to, in which the segmental guides are arranged to pass working-fluid two or more times either in one direction only or to and fro through the rotating blades in one or more of the separate chambers, only a small pressure-drop being permitted in each chamber. The invention further consists in a modification of the partial-admission turbine according to my Patent No. 25402, the feature of the modification being that the working-blades are made of crescent formation instead of the formation characteristic
