No. 27077.—21st December, 1909.—CLAUDE ALBEMARLE BETTINGTON, of the Junior United Service Club, 11 and 12 Charles Street, St. James’s, and of 14 Half-moon Street, Piccadilly, London, England, Lieutenant in the British Land Forces. Improvements in and relating to apparatus for pulverising coal and other materials.

Extract from Specification.—According to the present invention the pulverising-chamber is provided with an outlet for the mixture of pulverised material and air, which outlet is constructed so that it forms a curve in continuation of the internal circumferential surface of the chamber. The mixture of pulverised material and air is ejected from said outlet vertically upwards into a chamber provided with a suitable baffle or baffles which cause the mixture to be deflected in a downward direction whereby the larger particles of material fall to the bottom of said chamber, from which it is returned to the pulverising-chamber by suitable means. The material to be pulverised is delivered to the pulverising-chamber at the earliest point where the pulverising action of the beaters is capable of commencing, so that said action may take place over practically the whole of the effective internal periphery of the chamber.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, 9s.)

No. 27103.—30th December, 1909.—ERIC BROWN, of Bahnhofsweg, Baden, Switzerland, Engineer. Improvements in methods of working steam or gas turbine plants.

Claims.—(1.) A method of working steam or gas turbine installations for varying powers and speeds of revolution in which the steam or gas is caused to pass successively through all portions of the turbine for low powers and speed of revolution, while for higher powers a corresponding number of turbine portions are supplied simultaneously with live steam by means of separate additional nozzles, and the steam passing from the preceding stages is provided with a path to the following stage without having to pass through the stages that are supplied with live steam in such a manner that the stages supplied with live steam are connected in parallel, and at the same time provide a larger cross-section for the flow of steam whereby the greatest possible economical utilisation of the steam for every power and number of revolutions of the installation is effected without shutting off any portion of the turbine. (2.) A modification of the method according to claim 1, in which the several turbine portions are arranged on several shafts.
