No. 23334.—19th August, 1907.—PARNELL RABBDGE, of Water’s Road, Neutral Bay, North Sydney, New South Wales, Australia, Electrician. An improved electric secondary cell.

Claims.—(1.) The improved electric secondary cell consisting of a suitable negative element, preferably oxidized lead, a positive element consisting of a suitable metal that has a strong affinity for oxygen and capable of ready amalgamation with mercury, such as zinc, magnesium, cadmium, and the like, in combination with an electrolyte composed of a solution of the sulphate of the metal of which the surface of the negative pole is composed, mixed with a solution of sulphate of mercury, as specified. (2.) In an improved electric secondary cell, an electrolyte composed of a solution of a sulphate of the metal that forms the positive element of the cell (such as a solution of sulphate of zinc) in combination with a solution of sulphate of mercury, as set forth, and for the purposes specified.

No. 23335.—19th August, 1907.—THOMAS CARTER REYNOLDS, of 105 Williams’ Road, East Prahran, Victoria, Australia, Manufacturer (assignee of Jean Ybert, Andre Desanges, and Joseph Alloatti, of Clermont-Ferrand, France, Manufacturers). An improved process and apparatus for drying macaroni or other foodstuffs.

Extract from Specification.—My improved process consists essentially of circulating a (more or less) very damp or moist atmosphere continuously in a closed chamber over or through the foodstuffs to be dried, and also in the utilisation of a suitable moisture-absorbing mixture or compound to regulate the degree of moisture in the said atmosphere drying the said foodstuffs. If the atmosphere be too damp or moist the foodstuffs are apt to get mouldy, whereas, if not sufficiently damp, they may crack and split owing to the rapid circulation of the said atmosphere. The same atmosphere is used continuously throughout the drying operation. In drying long macaroni, which is very delicate, I force the damp or moist atmosphere through the tubes of macaroni, and thus dry the inside first. The difference of diameter between the inside and outside of macaroni frequently caused it to split and break if it dried first outside; but if dried first from the inside it hardens equally all through, and without danger to the half-dried parts. The atmosphere generally must be very damp or moist, but the degree depends upon conditions. By my improved apparatus I provide means whereby the same damp or moist atmosphere is circulated continuously over or through the foodstuffs; means whereby the atmosphere is diffused over or through the foodstuffs evenly; means whereby the foodstuffs can be handled expeditiously and with ease and precision.

No. 23336.—19th August, 1907.—ALBERT VICTOR DEAR, of 15 Wattle Tree Road, Malvern, Victoria, Australia, and DAVID PHILIP DEAR, of Wollongong, New South Wales, Australia, Dentists. An improved dentists’ framework for supporting artificial dentures.

Extract from Specification.—Our invention relates to the framework used by dentists for supporting casts for artificial upper and lower teeth. In the past some of these frameworks did not permit of the adjustment that increased practice and experience has shown desirable. The object of our invention is to provide a framework whereby three adjusting mediums are introduced. Not only can the upper cast be moved bodily up and down from a pivot-pin at its rear, or its front end be moved circumferentially on a locking-screw or pivot-pin at the back end of the upper cast holding-plate, or the said front end be moved backwards or forwards, but it can also be so adjusted that the right-hand side of the said cast will descend before the left, or the left before the right, or the back of the cast before the front, or the front before the back. Or the cast end of the head-plate may be moved to the left, and the cast end of the upper cast holding-plate to the right, and there locked. Or the cast end of the head-plate may be moved to the right, and the cast end of the upper-cast holding-plate to the left. It, in fact, enables a multiplicity of adjustments to be effected. Both accuracy and precision are hereby assured, and with the minimum expenditure of time.

No. 23340.—22nd August, 1907.—GEORGE GARIBALDI TURRI, of 364-366 Collins Street, Melbourne, Victoria, Australia, Registered Patent Attorney, &c. (nominee of Hiram Wheeler Blaisdell, of 334 Pacific Electric Building, and Harry Alexander Brooks, of 605 Trust Building, Los Angeles, California, United States of America, Engineers). Improvements in or relating to filter-leaves.

Extract from Specification.—The leaf being supported in a suitable receptacle by means of castings 13, and sleeves 21 being connected to a pipe passing out of the receptacle, material to be filtered is introduced into the receptacle. A greater pressure is caused to be exerted upon the material outside the filter-leaf than exists within the same. The filtrate passes through the sheets 1 and 2 of filter-material into the grooves 4 and 5 of distenders 3, and flows through perforations 18 into pipe 17, which delivers it to any suitable means for carrying to the place desired. A cake or layer of residuum is formed upon the surface of the leaf, being more readily retained thereon by reason of the said surface being corrugated. This cake may be treated by having reagents and washes forced through it in the usual manner. To discharge the cake from the leaf, fluid under sufficient pressure to overcome the pressure from without the leaf is admitted to the interior of the leaf through pipe 17. This fluid going up through the grooves 4 and 5 of distenders 3 passes through the sheets of filtering-material 1 and 2, whereupon the cake of residuum falls from the filter-leaf. The sheets of filtering-material being stretched over substantially curved surfaces between their points of attachment to each other, there is no possibility of flexure and consequent cracking of the material as the pressure varies from one side to the other of the material. The deflecting-wings 8 prevent furrowing of the cake by drip from the supporting rail.

No. 23348.—22nd August, 1907.—ROBERT WILLIAM CROY, of Chertsey, New Zealand. Improved means for lifting posts out of the ground, and for other analogous purposes.

Claims.—(1.) Means for the purpose indicated herein, consisting of a lever bar or pole pivotally carried upon a truck and provided with a pair of rearwardly extending arms, a pair of gripping-jaws hinged to the respective arms and normally extending inwards towards each other, and means whereby the jaws may be raised on their hinges and retained in the raised condition, substantially as specified. (2.) Means for the purpose herein indicated, consisting of a lever bar or pole pivotally mounted on a truck, a pair of rearwardly extending arms, a pair of jaws hinged to the respective arms, springs for keeping the jaws normally turned inwards towards each other, a rod slidably mounted on the lever-pole, a pair of chains respectively connected to the gripping-jaws and to this rod, and an adjustable stop-piece upon the rod, substantially as specified. (3.) The general arrangement, construction, and combination of parts in my improved means for lifting posts out of the ground, and for other analogous purposes, substantially as described and explained, as illustrated in the drawings, and for the several purposes specified.

No. 23349.—22nd August, 1907.—AUBREY CLAUDE BARTLETT, of Yerranderie, New South Wales, Australia, Mine-manager. Apparatus for preventing the escapement of dust caused by mining-drills of the pneumatic type.
