No. 23385.—28th August, 1907.—WELLINGTON PARKER KIDDER, of 18 Robeson Street, Jamaica Plain, Boston, Suffolk, Massachusetts, United States of America, Engineer, and CHARLES WILLIAM SPONSEL, of 36 Pearl Street, Hartford, Connecticut, United States of America, Engineer. Improvements in typewriting machines.

Extract from Specification.—Clicking of pawl and ratchet mechanism, or the noise created by other escapement devices employed in connection with the feeding mechanism of carriages of typewriters, whenever they are returned to begin a new line, is a constant source of annoyance, and especially is this the case in machines of the type shown, wherein a substantially noiseless operation of the remaining operative mechanism of the machine has been secured, as a silent operation of the other mechanism renders any noise produced by the escapement mechanism more noticeable. It has therefore been found desirable to provide a construction wherein the carriage, although the feed-pinion thereof is constantly in mesh with the feed-rack thereof, may be returned to its initial or line-commencing position without the production of any noise whatever, or whereby the same may be readily set back one or more letter spaces at will.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, £1 15s. 3d.; drawing, 3s.)

No. 23390.—26th August, 1907.—CHARLES SUTTIE, of Waiharoa, New Zealand, Flaxmiller, and MONTAGUE HARRISON WYNYARD, of Auckland, New Zealand, Solicitor. A new or improved means for catching flax or the like after stripping.

Claims.—A means for catching blades of New Zealand flax and the like as they leave the stripper, comprising two rotating grooved or flanged pulleys revolving horizontally in the same plane, one pulley having its axle so mounted in a fixed bush as to be capable of being at least partly rotated, and having fixed to such rotatable axle an arm at the end of which is mounted the axle on which the other pulley revolves, with an endless travelling band or bands revolving such pulleys, and in the travel thereof led on to the pulley on the rotatable axle, thence on to the other pulley, and back to or past the first-mentioned pulley, and placed and operated, substantially as specified.
(Specification, 4s.; drawing, 1s.)

No. 23395.—26th August, 1907.—MARCONI’S WIRELESS TELEGRAPH COMPANY, LIMITED, of 18 Finch Lane, London, England, Electricians (assignees of Guglielmo Marconi, L.L.D., D.Sc., of 18 Finch Lane, aforesaid). Improvements in receivers for wireless telegraphy.

Claims.—(1.) In a receiver for electric oscillations, the combination of a circuit containing an oscillation valve and the secondary of an induction coil, and a second circuit containing the primary of the induction coil and a detector, substantially as described. (2.) The combination with the subject-matter of claim 1 of a condenser in the first circuit, substantially as described. (3.) Receivers for wireless telegraphy, substantially as described and illustrated in the drawings.
(Specification, 2s. 9d.; drawing, 1s.)

No. 23403.—31st August, 1907.—JOHN ROY MASSON, of Wandong, Victoria, Australia, Assayer and Metallurgist. An improved wet process for the recovery of antimony in a pure state from ores, concentrates, tailings, and slimes containing it.

Claims.—(1.) The described process, consisting in dissolving the antimonial contents of the material with a hot or cold solution of caustic soda, caustic potash, or other alkali, recovering the antimony in solution as sulphide of antimony by the addition of sulphuric acid, dissolving the sulphide of antimony precipitate with chlorine gas, at the same time forming chloride of antimony and precipitating the antimony contained in solution as pure antimony by introducing pieces of tin, copper, lead, zinc, or iron, substantially as described. (2.) Dissolving the antimonial contents of the material (when containing no more than about 10 per cent.) direct with chlorine gas without previous use of caustic soda, caustic potash, or other alkali, washing chloride of antimony out, and precipitating from solution with tin, copper, lead, zinc, or iron, substantially as described.
(Specification, 2s. 9d.)

No. 23404.—3rd September, 1907.—PHILIP SYDNEY WHITCOMBE, of Education Office, New Plymouth, Taranaki, New Zealand, Secretary. Improved device for connecting wires to be strained.

Claims.—(1.) A device for connecting wires, constructed, arranged, and operating substantially as specified. (2.) A device for connecting wires, consisting of a metal bar drilled with holes of a diameter corresponding with the gauge of and adapted to receive the wires to be connected, substantially as specified.
(Specification, 1s. 6d.; drawing, 1s.)

No. 23405.—4th September, 1907.—ALWIN FISCHER, of O’Connell Street, North Adelaide, South Australia, Plumber. Improvements in dressing sterilisers.

Extract from Specification.—Instead of the method usually adopted of closing the opening from the outside, which requires strong pressure to overcome the pressure of the steam inside, I adopt the method of closing the opening from the inside, thereby utilising the pressure of the steam in the apparatus to help in closing the joint and thus prevent leakage.

[NOTE.—The above extract from the specification is inserted in place of the claims.]
(Specification, 4s.; drawing, 1s.)

No. 23410.—4th September, 1907.—CHARLES HENRY EDMUND HOPE-JOHNSTONE, of Aramoho, Wellington, New Zealand, Factory Manager (assignee of the Company Nutricia Centrale fur Backhausmilch, Gesellschaft mit beschrankter Haftung, incorporated according to the laws of the Kingdom of Prussia, domiciled in 111 Potsdamerstrasse, Berlin, Prussia, German Empire, the assignees of Alexander Bachaus, of Berlin, German Empire, Doctor of Philosophy and Professor of Agriculture). Improved treatment of milk to render it suitable as food for infants and children.

Claims.—(1.) The treatment of the milk of cows or other domesticated animals, consisting in the separating of the said milk into cream and skim-milk, subjecting the skim-milk to the combined action of a ferment capable of converting the casein into soluble albumen and a ferment capable of precipitating casein, rendering the said ferments inoffensive after due action, and adding cream and milk-sugar after separation of the precipitated remainder of casein from the liquor, substantially as and for the purpose described. (2.) The treatment of the milk of cows and other domesticated animals, consisting in separating the said milk into cream and skim-milk, subjecting the skim-milk to the combined action of a ferment capable of converting casein into soluble albumen and a ferment capable of precipitating casein, rendering the said ferments inoffensive after due action, and adding cream and milk-sugar after separation of the precipitated remainder of casein from the liquor, and treating the separated cream by mixing it with water, milk, and milk-sugar for the purpose stated.
