No. 30431.—17th December, 1910.†—MOSE WILBUSCHWITSCH, of Nischninovgorod, Kanavino, Russia, Factory Director. Process and apparatus for converting fats and fatty acids into like bodies of higher melting-point by the contact method.

Claims.—(1.) A process for converting fatty acids and fats into like products of higher melting-point by use of a catalyst according to the contact method, wherein the material is intimately mixed with the catalyst, and the mixture is introduced in a finely sprayed condition into an autoclave under pressure and at a raised temperature so that it meets a current of hydrogen therein, substantially as described. . . . (4.) Apparatus for operating according to the process referred to in the preceding claims, comprising an oil-reservoir and a catalyst-reservoir connected by a differential pump, a mixing-device for mixing the oil and the catalyst, one or more autoclaves arranged in series or in parallel and provided with a heating-jacket, a centrifugal apparatus or the like for separating the oil and catalyst, and devices for cooling, purifying, and returning the hydrogen and for returning the catalyst, substantially as described. (Specification, 10s.)

[NOTE.—Here follow six other claims.]

No. 30432.—30th January, 1911.†—MOSE WILBUSCHWITSCH, of Nischninovgorod, Kanavino, Russia, Factory Director. Process and apparatus of refining hydrogenized fats for producing eatable fats.

Claims.—(1.) Process of making eatable fats from hydrogenized fats consisting in saponifying the free acids by very concentrated alkali lye while carefully avoiding any excess of water, removing the vaporizable substances, and cooling the substances within vacuum chambers in a carbonic-acid atmosphere, substantially as described. (2.) Vacuum chamber for practising the process referred to in claim 1 having a coned lower part, and provided at its upper part with a funnel-shaped separator-bell by means of which any oil that might be carried along is held back, substantially as described. (Specification, 5s.)

No. 30563.—27th November, 1911.†—CATHERINE MARIA MEIN O’CONNOR, of Duporth, Oxley, Queensland, Australia, School-mistress. Improvements in calculating-machines.

Extract from Specification.—I arrange one or more stationary dials each having a circle of numbers concentric, within each of which rotates a disc bearing on its face similar numbers coinciding with the before-mentioned numbers, but arranged in the reverse order. Each disc is revolvable by hand, suitable gearing being provided by which, when the preceding disc is turning from the last number to nought, the succeeding disc moves from nought to one. At the same time the gearing is such that, should it be desired to operate any disc other than the first, the preceding disc will not be interfered with. For multiplying and dividing, each disc must be specially divided according to the multiplier or divisor. (Specification, 10s.)

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

No. 30634.—13th December, 1911.—THOMAS McCORMACK (BARNINGHAM AND CO.), of Dunedin, in the Dominion of New Zealand, Ironfounder, &c. Improved high-pressure boiler for ranges and the like.

Claims.—(1.) In high-pressure domestic boilers for ranges and suchlike, a boiler that surrounds the fire on three sides, combined with flues passing under the said boiler and between it and the oven, and with corrugations for increasing the heating-surface, all substantially as shown on the drawing, and as explained and as described. (2.) In high-pressure boiler for ranges and the like having flues under the back and under the side, angled underneath to follow the direction of the fire, with corrugations for increasing the heating-surface, all substantially as set forth. (3.) In range-boilers, a boiler, U-shaped on plan, with flues and corrugations as set forth, being connected to the usual cylinder by preferably straight pipes running parallel from the said boiler to the said cylinder, all substantially as set forth. (Specification, 2s. 3d.)

No. 30672.—22nd December, 1911.—EDMUND JOHN WHITE, of Auckland, in the Dominion of New Zealand, Commercial Traveller. Improved construction of folding wardrobe.

Claim.—(1.) In an article of the class indicated, the combination with a suitable back, of a pair of side members hinged thereon so as to be capable of extending at right angles therewith or folding against the rear face of such back, a pair of doors hinged upon and adapted to fold against the inner face of said side members, and a pair of members forming the top and bottom respectively, both hinged upon said back so as to be capable of folding against the forward face of said back, substantially as and for the purpose set forth. (Specification, 2s. 6d.)

[NOTE.—Here follows one other claim.]

No. 30675.—28th December, 1911.—CLAUDE HUDSON DAVIS, of Church Place, Wanganui, in the Provincial District of Wellington, in the Dominion of New Zealand, Engineer. Improvements in milk-releasers.

Extract from Specification.—An intermediate valve is provided between the two vessels normally adapted to be closed, but upon the float falling through the lower vessel being emptied of milk it will operate the intermediate valve, thus allowing the air in the lower vessel to be exhausted therefrom, and allowing the inlet-valve to immediately open and the milk which has been entrapped in the upper vessel to flow into the lower vessel. (Specification, 5s. 9d.)

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

No. 30696.—6th January, 1912.—CLAUDE HUDSON DAVIS, of Church Place, Wanganui, in the Dominion of New Zealand, Engineer. An improved vacuum pump.

Extract from Specification.—A cylinder is pivoted on trunnions in a frame, while the piston-rod thereof is provided with a connecting-rod head working upon a crank-shaft. The cylinder is adapted to oscillate upon the trunnions synchronously with the revolutions of the crank-shaft. A vacuum chamber parallel to the length of the cylinder communicates with each end of the cylinder by means of ports. Inlet-valves normally close the communication at both ends of the chamber to the cylinder. Outlet-valves at each end of the cylinder are adapted to open outwards in order to allow the air which has been exhausted into the cylinder to be expelled therefrom. The pipe through which the air is exhausted is lead to the vacuum chamber through one of the trunnions, this trunnion being hollow and communicates with the vacuum chamber. A special joint is made between the exhaust-pipe and the trunnion in order to allow the cylinder and trunnion to oscillate while the exhaust-pipe remains stationary. (Specification, 4s. 6d.)
