Extract from Specification.—The apparatus comprises a cylindrical or rectangular shaped vessel, portions of which may be perforated, mounted in suitably shaped frames or standards to swing or oscillate through 360° or thereabouts. The vessel may have an outer casing to contain the washing-liquor. A loose shaft passes through the centre of vessel, and bearing closely against, but not attached to, one side of this shaft, and parallel to it, is a partition that is fixed to the vessel and which moves with it. Mounted upon the opposite side of this shaft, and fixed to it, is a movable partition which can be oscillated through the shaft from the outside of vessel, be secured to the vessel, or be held vertical by springs. The partition, which is permanently fixed to the oscillating vessel, is built up of longitudinal ribs, some or all of which may be of convex shape, and the other partition of longitudinal ribs, some or all of which are of concave shape. An overflow arrangement is provided to allow the dirty water to pass out of the vessel while the clean is running in.

No. 29796.—24th June, 1911.—COULLS, CULLING, AND COMPANY, LIMITED, a company incorporated in New Zealand, and having its registered office at Dunedin, New Zealand (assignees of Charles Bristow, of Christchurch, New Zealand, Engineer). Improvements in envelopes.

Extract from Specification.—According to this invention, an envelope is provided having its joining-seam (1) made in the middle of the rear face (2) of the envelope so as to provide a strong hold for an eyelet (3) fixed through the double thickness of the seam and surrounding and protecting a hole made therein. The upper end (4) of the rear face of the envelope has an inwardly folded under-lip (5) to prevent the contents, such as seed, from escaping. A staple (6) is provided attached to the flap (7) of the envelope. In the form shown in Figs. 1 to 4 inclusive this staple consists of a spring wire folded and twisted at the fold twice round an eyelet (8) in the flap (7), the prongs of the staple terminating in curved outwardly turned hooks (9) (10).

No. 29797.—27th June, 1911.—ALEXANDRE TRIFONOFF, Engineer, and DANIEL GARDNER, Chemist, both of the Technological Institute of St. Petersburg, St. Petersburg, Russia. Process for treating sulphurous antimony or arsenic ores.

Extract from Specification.—The novel process resides in the fact that the sulphurous ore is melted preferably with sodium-sulphate, sulphide of iron (for example, pyrites or other iron-ore), and carbon, eventually with the addition of some soda, but this melting is not carried as far as the formation of the pure sulphi-salt (as suggested, for example, by MacArthur in employing sulphate and carbon in the melting-process), but in such conditions that besides the sulphi-salt (Na₃ Sb S₄ for example) oxide (Sb₂ O₃, for example) is obtained. The rest of the mineral passes into the slag, in which the iron is contained in the form of the silicate (2 FeO SiO₂).
