88 THE COLLIERY GUARDIAN July 9, 1915. vapours and gases liberated when the slag is latomised, so that these vapours and gases do not travel through the drum with the slag. The air, introduced in a cold state, absorbs heat from the slag in the course of its travel through the drum, -and thus greatly assists the cooling process. This enables the length of the drum to be consideraby reduced, h ___A. w- /; and less driving power is required. Admixtures to be used with the slag can be introduced in a dry state, in the course of the atomising action of the rotary drum, and the quality of the slag is thus improved. The accompanying drawing is a longitudinal section of one form of the appa- ratus. (Three claims.) NEW PATENTS CONNECTED WITH THE COAL AND IRON TRADES. Applications for Patents. 9411.

The following list of British Patents, which have been granted in favour of residents of Germany, Austria, or Hungary, is furnished in view of the new Patents Acts, which empower the Board of Trade to confer upon British subjects the right to manufacture under enemy patents, which right, when acquired, can be retained after the war, and is specially compiled for the Colliery Guardian by Lewis Wm. Goold, chartered patent agent, 5, Corporation- street, Birmingham. It is desirable in the first instance to obtain the latest particulars upon the Patents Register. If any patent listed has been assigned to a non-enemy proprietor, the law does not apply. 6917/13. Furnaces; charging. An automatically operated apparatus for charging furnaces comprises a number of exchangeable charging vessels inserted through the roof of the furnace, and having closure devices operated at intervals to allow the contents to be deposited. By substi- tuting vessels of larger or smaller capacity, the rate of charging can be varied. Chemische Industrie Akt.-G-es., and L. Singer, Germany (dated March 22, 1912). 6944/13. Furnaces; grates. ‘A device for adjusting later- ally the hollow reciprocating bars of oblique or stepped grates comprises an adjustable cheek or plate arranged in a box-like girder in one or both side walls of the furnace, on a level with the grate bars. The plate is moved perpen- dicularly to the walls by means of one or more pivoted wedges adapted to engage with machined surfaces on the girder and plate. The wedges are mounted on the square portions of rotatable pins provided with handles and nuts. Bolts serve to guide the plate. P. Werger, Berlin (dated May 29, 1912). 7299/13. Composition fuel. A coating composition for fire lighters. C. H. Schuster, Germany. 7324/13. Briquettes; paints; varnishes. Waste sulphite lye or cellulose lye is inspissated and mixed by pro- longed stirring with carbon bisulphide to form a brown or grey product, which is applicable as a varnish, paint, covering, or binding medium. Anthracite, hard coal, or the like may be mixed with the binder with the aid of heat and briquetted, no coking being necessary to render the briquettes resistant to the atmo- sphere. Oil, resin, wax, paraffin, camphor, pitch, or the like, in a dissolved state, may be added to the carbon bisulphide to make the briquettes more resistant and coherent, and the carbon bisulphide may be removed or not subsequently. The binder may also be used for coating coal briquettes of any kind, by dipping, and for making moulded articles of fibrous material. P. G. Muller, Berlin. 7413/13. Sinking shafts. In sinking shafts in boggy ground a shield is used near the bottom of the shaft, and the space beneath is filled with water from the surface under a pressure greater than the pressure of the surrounding water or other material, in order to prevent breaking in of the shaft wall. G. Schneiders, Prussia. 7601/13. Distilling fuel. Apparatus for the distillation of fuel comprises a vertical retort, which is heated by the combustion of gas from a-generator to a high temperature in the lower part and a lower temperature in the upper part, the fuel space in the retort being confined to a thin layer by an internal core, which is perforated in the upper part of the retort, so as to facilitate the escape of gas, and is imperforate in the lower part, bo as to ensure that the steam introduced has a long path through the fuel.
