Claims.—(1.) A lining-plate for a tube-mill and recesses therein for holding grinding bodies, said recesses being somewhat wider at the portion adjacent to the axis of said mill than at the portion remote from the axis, and adapted to retain material wedged therein. (2.) A lining for a tube-mill, comprising a series of ribs formed upon the interior surface of said mill, said ribs being narrower at the portion adjacent to the axis of said mill than at the portion remote from said axis, and grinding bodies held frictionally in the recesses between said ribs. (3.) A mill of the character described, comprising a drum adapted to contain material to be pulverised, and a grinding or abrading material, said drum being provided with a lining having recesses adapted to retain the grinding material wedged therein.

No. 23501.—21st September, 1907.—CHARLES CHEERS WAKEFIELD, of 27 Cannon Street, London, England, Merchant. Improvements in gas-burners.

Claims.—(1.) In a gas-burner, the combination with the burner orifice of a needle-valve arranged to project there-through, for the purposes described. (2.) In a gas-burner, the combination with the burner orifice of a solid needle-valve arranged to project therethrough, for the purposes described. (3.) In a gas-burner, the combination with the burner orifice of a needle-valve arranged to project there-through, a shield or directing mouth surrounding the orifice and flaring outwardly, with or without air-holes circumferentially arranged with respect to the orifice, substantially as described. (4.) In a gas-burner, the combination of an orifice A³, a needle-valve B surrounded by a directing-mouth A⁴, and means for indicating the position of the needle-valve, such for example as the dial I and pointer J. (5.) In a gas-burner, a joint between the burner-pipe or a pipe connected thereto and the supply-pipe, comprising a gland attached to one pipe into which the other fits, and a nut screwing into the gland to compress packing within the gland. (6.) In a gas-burner, a swivel-joint constructed and arranged substantially as described and illustrated in Fig. 1 of the drawings. (7.) A gas-burner for a flare-light constructed, arranged, and operating substantially as described and illustrated in Figs. 1 to 4 of the drawings.

No. 23505.—23rd September, 1907.—ARTHUR REDMAN WILFLEY, of 1300 High Street, Denver, Colorado, United States of America, Mining Engineer. Improvements in ore-roasting process.

Extract from Specification.—In my improved process I make provision for an even roast of the ore by causing it to travel downwardly with a current of hot air instead of upwardly against said current, as is the usual custom. Furthermore, at the lower extremity of the flue through which the ore is travelling downwardly I provide a cooling medium, preferably a water-jacket which is downwardly and outwardly inclined from the flue, whereby the ore is simultaneously cooled and carried outwardly away from the flue preparatory to its discharge from the furnace.

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

No. 23506.—23rd September, 1907.—CHARLES PARRIS STEWART, a citizen of the United States, of 2915 Harvard Boulevard, Los Angeles, California, United States of America, Chemist. Process for making sugar.

Claims.—(1.) The process of forming sugar synthetically, which consists of combining carbon, hydrogen, and oxygen. (2.) The process of forming sugar synthetically, which consists of mixing carbon, hydrogen, and oxygen, and then passing the mixture through magnetic and electric influences. (3.) The process of forming sugar by the synthetic means of combining carbon with hydrogen and oxygen, and then adding free hydrogen and oxygen to the combination. (4.) The process of forming sugar synthetically, which consists of combining carbon with hydrogen and oxygen, then adding free hydrogen and oxygen to the combination, and then passing the mixture through magnetic and electric influences. (5.) The process of forming sugar synthetically, which consists of combining hydrogen and oxygen with carbon to form CO and C₂H₂, then adding more hydrogen and oxygen, and lastly passing the resultant mixture of gases through magnetic and electric influences. (6.) The process of forming sugar, which consists of first decomposing steam, then passing a portion of the decomposed steam through heated carbon, then mixing the remaining portion of the decomposed steam with the gases passed through the carbon, and finally subjecting the resultant mixture to mechanical compression and magnetic and electric influences. (7.) The process of forming sugar, which consists of mixing together eight parts of CO, eight parts of C₂H₂, fourteen parts of H₂, and seven parts of O₂, and then subjecting the mixture to mechanical compression and magnetic and electrical influences.

No. 23509.—24th September, 1907.—ALFRED GEORGE JACKSON, of Ann Street, Brisbane, Queensland, Australia, Electrician. A system of electrical releasing mechanism for turret clocks, bell-striking apparatus, and other purposes.

Claims.—(1.) A system of electrically releasing mechanism for turret clocks, comprising an arm suitably loose on its spindle, but having a light pressure forward and held in position by an arm attached to the armature of an electro-magnet in circuit with a source of electric impulses as a time-switch and battery, the said spindle being driven by suitable gearing and weights, substantially as set forth. (2.) In a turret clock, mechanism having a snail on the minute spindle in conjunction with the releasing arm and electro-magnet, which snail allows an arm to make a momentary electric contact at definite times in a circuit comprising a battery and electro-magnet to release the striking or chiming mechanism, substantially as described. (3.) In a clock, mechanism of the type set forth, an arm B.C. geared to the minute spindle K, so that for every half-minute of pointer on this spindle the arm B.C. turns a complete or portion of a revolution, the number of arms on A depending on the amount of rotation, for the purposes described and illustrated.

No. 23512.—24th September, 1907.—THOMAS JAMES McBRIDE, of 136 Papanui Road, Christchurch, New Zealand, Gentleman. Improvements in resilient wheels for vehicles.

Extract from Specification.—The improvements have been devised to generally improve the construction of such arrangements, but especially to more effectively secure the tread from lateral or radial displacement, to prevent creeping of the tread, to minimise friction between the tread and casing, to prevent the ingress of grit and dust and minimise the liability of the tube being pinched, and also to provide simple means for enabling the whole tire to be readily taken to pieces.

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