No. 30649.—21st December, 1911.—GEORGE JOHN HOSKINS, A.M.Inst.M.E., of Wattle Street, Sydney, in the State of New South Wales, Commonwealth of Australia, Engineer. Improved appliances for preparing the moulds for casting iron pipes.

Extract from Specification.—This invention comprises a fixed central island or tower upon which is axially mounted a jib-crane worked by a motor. Surrounding the base of the tower is an annular turntable that is operated by gearing actuated by a motor. Upon the upper surface of the turntable is an annular rail the function of which will be hereafter explained. The mould-cases are hung upon the top ring-edge of the turntable. Centred upon the tower above the turntable is a segmental carriage adapted to travel round the tower, over the turntable, in a complete circle. The outer end of the segmental carriage is supported upon wheels that travel over the turntable, round the tower, upon the annular rail above-mentioned. On the outer end of the segmental carriage is reared a scaffold or framework that carries the sand-rammers, which are of a peculiar construction, as set forth in the specification of a prior patent, No. 28324, dated 24th August, 1910, of the Dominion of New Zealand. The sand-rammers are operated by gearing actuated by a separate motor. The patterns or cores are carried round by the jib-crane and dropped into the mould-casings that are hung, in pairs, radially around the ring-edge of the turntable.

No. 30658.—22nd December, 1911.—AUGUST NIELSEN, of Hamburg, Germany, at present residing at Wanganui, New Zealand, Inventor. A process for the production of casein from milk.

Extract from Specification.—The process consists in storing the milk (preferably skimmed milk) until such time as it coagulates by souring, then subjecting the mass to heat in order to cause the casein to separate from the whey by rising to the top thereof. This casein is then skimmed off and washed with hot water, after which it is allowed to drain and settle, and is then pressed, and the excessive moisture expressed therefrom. The casein is then ground into small pieces and dried, when it will be ready for transport.
