No. 30879.—14th February, 1912.—THOMAS HOWARD CUNNINGHAM, of Auckland, New Zealand, Ironworker. An improved form of safe or chamber for keeping meat and other provisions cool and clean.

Extract from Specification.—Making a frame which is so shaped that it carries on its top a pan formation suitable for holding water, while the bottom of the formation rests in a tray having fitted therein a pipe outlet. The formation is preferably square-shaped, and to one of its sides a skeleton door is hinged. A piece or pieces of material, preferably towelling or of suchlike woven substance, is tightly drawn around the other three sides so as to reach from the top to the bottom of the frame or formation, or nearly so, and a smaller piece of the same material is fitted on the skeleton door so as to fully cover it. Pieces of flannel or the like material are bent over the top edges of the pan, so that one end of each piece of flannel will dip to the floor of the pan, and the other end of the flannel will reach over to and be on the towelling beneath it. (Specification, 3s.)

No. 30880.—12th February, 1912.—ARTHUR HERBERT PENFOLD, Labourer; WILLIAM PERCY WALLACE, Electrical Engineer; and ALEXANDER MACDONALD, Blacksmith, all of Dunedin, New Zealand. Cutter and draw-off pipe for kerosene-tins and the like.

Claims.—(1.) A cutter for kerosene-tins and the like comprising, in combination, a handle and a tubular portion, said tubular portion having two curved sharpened edges opposite and crossing each other and two straight edges diametrically opposite each other, each straight edge and curved edge meeting in a point, substantially as described. (2.) A combined cutter and draw-off pipe for kerosene-tins and the like consisting of the combination with a cutter, according to claim (1), of a spout connected to the extended tubular portion of the cutter, and means for holding the device in position on a tin, substantially as described. (Specification, 3s. 3d.)

[NOTE.—Here follow two other claims.]

No. 30886.—21st February, 1911.†—CHARLES WATSON, of Sunny Lea, Glen Huon, Tasmania, Australia, Fruit-grower. Improvements in and relating to fruit-graders.

Extract from Specification.—The apparatus consists of a large cylinder that is rotated by any convenient means, and in which are a number of perforations spirally arranged and graduating in size, and internal spiral avenues which include such perforations. A suitable chute or feeding-device is employed to convey the fruit to be graded into the cylinder, through which it will move along the spiral avenues as the cylinder is rotated. The holes or perforations increase in diameter towards the lower end of the machine, and spherical fruit, such as apples, will, in passing through the cylinder, eventually reach an opening large enough to permit the piece to fall through it on to a canvas chute or conveyor below the cylinder which will carry the fruit clear of the machine. (Specification, 6s. 3d.)

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

No. 30893.—29th June, 1911.†—THE BRITISH-AUSTRALASIAN TOBACCO COMPANY PROPRIETARY, LIMITED, of 45 Park Street, Sydney, New South Wales, Australia, Manufacturers (assignees of William Edward Shaw, of 45 Park Street aforesaid, Director). Improvements in hinging the lids of tins and like containers.

Extract from Specification.—According to the present invention, the tin is hermetically sealed by soldering or otherwise securing a suitable closure or tagger on the top thereof. The lid having the pivot-pin secured to one side thereof is then placed over the tin, and a metal strip or plate having a recess stamped thereon at each end is soldered or otherwise secured to the side of the body of the tin so that the ends of the pivot-pin have bearings between said recesses and the side of the body. (Specification, 3s.)

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

No. 30894.—27th February, 1911.†—WILLIAM PHILPOT CURRAN BAIN, of Lochrin Ironworks, Coatbridge, Lanarkshire, Scotland, Manufacturer. Improvements connected with wire fencing.

Claim.—(1.) A dropper or standard made with laterally projecting flanges (b, c), each flange having raised or outwardly projecting studs or points, or equivalent, thereon, the fence-wires resting between the studs or points and being secured by means of wire ties or other fasteners, substantially as described. (Specification, 4s. 3d.)

[NOTE.—Here follows one other claim.]

No. 30895.—22nd March, 1911.†—HENRY JAMES REES, Works Foreman, of Llansamlet, Glamorgan, Wales, England, and THE METALS EXTRACTION CORPORATION, LIMITED, of Finsbury House, Blomfield Street, London, England. Improvements in or relating to the deposition of metallic salts from solutions containing them.

Claim.—(1.) A process for depositing salts of the kinds described from a solution containing them, which consists in subjecting a continuously moving thin film of the solution to the action of the hot gases from a coke fire. (Specification, 8s.)

[NOTE.—Here follow three other claims.]

No. 30897.—19th February, 1912.—ARTHUR FRANCIS BERRY, of 27 Woodville Road, Ealing, Middlesex, England, Electrical Engineer. Improvements in or relating to electrical heating apparatus.

Extract from Specification.—Recesses are provided to accommodate the bends of the conductor, and thereby to relieve the pressure of the confining elements thereon. When one or each of the confining elements has a flat surface adjacent to the conductor or to the holder upon which it is wound, the recess formation may be produced by inserting between the conductor or its holder and the confining element, or each confining element as may be required, a thin layer or thin layers of suitable electrically insulating but heat-transmitting material, as transparent mica, so shaped, dimensioned, and arranged as to be not opposite to the edge of the bends of the conductor. Such layer or layers may be additional to any layer or layers of similar material inserted between the wound conductor and the confining element or elements and having portions opposite to the bends of the conductor. Instead of employing a layer or layers of electrically insulating material such as described above for producing the recess formation, that formation may be produced by recessing the corresponding confining element or elements . . . the edge of the primary element is made without a flange or of less thickness than the main portion thereof, and the edge of the secondary element is formed with a flange adapted to bear against the edge of the primary element with or without interposed packing material. (Specification, 13s. 6d.)

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

No. 30899.—25th February, 1911.†—HUMBERT CANTONI and JEAN CHAUTEMS, both of Rue de Hesses Nr. 12, and EMILE DEGRANES, of Rue St. Leger Nr. 3, all in Geneva, Switzerland. Improvements in and relating to processes for extracting and recovering, in the form of potassium-bitartrate, the totality of the tartaric acid contained in the tartar or argol, lees, and, in a general manner, in all tartaric materials.

Claims.—(1.) A process for extracting and recovering, in the form of potassium-bitartrate, the totality of the tartaric acid contained in any tartaric materials whatever, this process consisting in employing such chemical reactions that for precipitating the cream of tartar only such solutions are employed which are obtained by the attack of the raw materials containing tartaric materials, this result being obtained by the judiciously combined employment of alkaline and acid reagents; oxalic acid and a salt of potassium being introduced into the cycle of operations if the raw materials do contain calcium-tartrate, the said introduction being made in order to permit the conversion of the said calcium-tartrate into insoluble calcium-oxalate and potassium-bitartrate; the rational application of the cycle of the described reactions reducing from 50 per cent. the whole employment of chemical reagents which are necessary for the usual processes, which are based upon an attack of the raw materials only by an acid or by an alkali. (2.) A process such as claimed in claim (1), substantially as described. (Specification, 6s.)

No. 30900.—19th February, 1912.—THE AZULAY SYNDICATE, LIMITED, of 8 Laurence Pountney Hill, Cannon Street, London E.C., England, Manufacturers (assignees of James Walter Henry Dew, of 8 Laurence Pountney Hill aforesaid, Engineer). Improvements in the manufacture of pneumatic-tire covers.
