No. 23546.—30th September, 1907.—HENRI HERREN-SCHMIDT, of 10 Boulevard Magenta, Paris, France, Industrial. Process for the extraction of metals and metalloids from their ores or compounds.

Claims.—(1.) A general process for extracting metals and metalloids from ores, natural or artificial compounds contained therein, characterized by the ores or compounds being submitted in an electric furnace, or in any apparatus capable of producing the same temperatures, to the separating action of boron, produced by deoxidizing by means of carbon a boron compound—boric acid, borates, &c.—and simultaneously to the deoxidizing action of carbon. (2.) By the application of said process to the treatment of bauxite, (a) the manufacture of artificial corundum practically free from iron and silica, and consequently having even more effective fireproof qualities than corundum obtained by the mere smelting of bauxite; (b) the manufacture of aluminium alloyed with boron; (c) the manufacture of an alloy of aluminium and ferro-boro-silicium. (3.) As new products utilisable in industry, the metals and metalloids by the processes set forth.

No. 23747.—21st November, 1907.—PARKER MACHINE COMPANY, a corporation duly organized and existing under and by virtue of the laws of the State of New York, United States of America (the assignee of Joseph Albert Ronchetti, of Woonsocket, Providence, Rhode Island, United States of America, Engineer). Platen-shifting mechanism for typewriters.

Extract from Specification.—This invention relates to typewriting-machines, and is directed more especially to improvements in mechanism employed for shifting the platen for different case printing. One of the objects of the invention is to provide improved means for shifting the platen to different positions at either side of a normal central position, so as to enable the same to receive impressions from any one of three type mounted upon each type-bar. Another object thereof is to provide simple and efficiently operating means for shifting the platen-frame, such that while the platen is always locked and firmly held in a normal central position the locking-means will in no wise oppose its being readily moved to carry the platen to other printing-positions. Another object is to provide improved means for locking the platen in either of its shifted positions. A further object is to provide mechanism of the above character which will operate to arrest the shifting movements of the platen or its return movements to normal position, substantially without noise. Other objects will be in part obvious and in part pointed out.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
