Claims.—(1.) The treatment of digester-soup to obtain therefrom a solid product usable as a fertiliser which consists in treating the soup or a concentrate thereof with a saturated solution of commercial ferric sulphate, in the proportions specified, substantially as described. (2.) The treatment of digester-soup to obtain therefrom a solid product usable as a fertiliser which consists in treating the soup or concentrate thereof with a saturated solution of commercial ferric sulphate and potassium-bichromate in the proportions specified, substantially as described. (3.) The treatment of digester-soup to obtain therefrom a solid product usable as a fertiliser which consists in treating the soup with a saturated solution of commercial ferric sulphate in the specified proportions to obtain a coagulum, and treating the separated liquors with a solution of potassium-bichromate to produce a further coagulation, and finally extracting water from the coagulum and drying the same, substantially as described. (4.) The treatment of digester-soup to obtain therefrom a solid product usable as a fertiliser which consists in coagulating the soup with the specified proportion of the red solution produced by the reaction of nitric acid on ferrous sulphate, extracting water from the coagulum, and drying it, substantially as described. (5.) The treatment of digester-soup to obtain therefrom a solid product usable as a fertiliser which consists in (a) coagulating the soup with the specified proportion of the red solution produced by the reaction of nitric acid on ferrous sulphate; (b) treating the waste liquors with the specified proportion of potassium-bichromate to produce a further coagulation; and (c) extracting water from the coagulum and drying the same, substantially as described. (6.) The treatment of digester-soup to obtain therefrom a solid product usable as a fertiliser which consists in (a) concentrating the soup by evaporation; (b) treating the concentrate with the specified proportion of a black solution produced by the reaction of a limited quantity of nitric acid on ferrous sulphate; and (c) concentrating and drying the coagulum so obtained, substantially as described.
(Specification, 5s. 3d.)

No. 11631.—18th May, 1899.—HERBERT ARTHUR SOMES, of 52, Pitt Street, Sydney, New South Wales, Manure-manufacturer. Improvements in the manufacture of meat-extract.

Claims.—(1.) The manufacture of meat-extract which consists in dividing and pressing the meat, immediately after killing, in a low temperature; digesting said juices at a temperature of about 350° Fahr.; and, finally, concentrating the digested product, substantially as described. (2.) In the manufacture of meat-extract, digesting at a temperature of about 350° Fahr. the juices pressed from the meat whilst at a low temperature, substantially as described.
(Specification, 2s. 6d.)

No. 11634.—18th May, 1899.—CHARLES HARPER, of Woodbridge, near Guildford, Western Australia, Gentleman. A sheaf-header appliance for threshers.

Claims.—(1.) In a sheaf-heading machine, the use of a revolving saw as the cutting or separating agent, substantially as and for the purposes set forth, and as illustrated in Figs. 1 to 4 of the drawings. (2.) In a sheaf-heading machine, the use of a revolving or band saw, having its cutting-edge of a serrated or sickle-toothed formation, substantially as and for the purposes set forth, and as illustrated in the drawings. (3.) In a sheaf-heading machine, the use of a continuous band-saw as the cutting or separating agent, substantially as and for the purposes set forth, and as illustrated in Fig. 5 of the drawings. (4.) In a sheaf-heading machine, having a circular or band saw as the separating agent, whose cutting-edge is of a sickle-tooth or serrated formation, in combination with a fixed cutting-table, and a travelling feed-apron for the sheaves, and a receiver for the grain-heads, the whole substantially as and for the purposes set forth, and as illustrated in the drawings.
(Specification, 5s. 3d.; drawings, 6s.)

No. 11648.—23rd August, 1898.—ADOLF VOGT, of 1 Soth-ringerstrasse, 5, Vienna, Austria, Engineer. Improvements in the manufacture of electrical resistances.

NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Great Britain,

Claims.—(1.) The process of manufacturing an electrical-resistance material from a mixture of a conductor and a non-conductor consisting in working such mixture into a paste or dough with water, moulding, casting, or otherwise converting such paste or dough into the shape desired, drying, and finally heating imbedded in carbon to a high temperature, substantially as described. (2.) The process of manufacturing a resistance-material having an approximately constant conductivity throughout a considerable range of temperature from a mixture of a non-conductor, graphite, and a metallic powder, consisting in making a paste or dough of such mixture with water, moulding, casting, or otherwise converting such paste or dough into the shape desired, drying, and finally heating imbedded in carbon to a high temperature, substantially as described. (3.) In the processes hereinbefore claimed, the substitution of a carbonisable material for carbon in the composition of the mixture, due provision being made for the escape of the gases generated during carbonisation, substantially as described.
(Specification, 3s. 3d.)

No. 11650.—25th May, 1899.—WILLIAM STAMM, of 25, College Hill, London, England, Iron and Steel Agent (assignee of Henry Livingstone Sulman, of 60, Gracechurch Street, London aforesaid, Analytical Chemist). Improvements in ball grinding-mills.
