No. 26556.—9th September, 1909.—HANS SIEGWART, of 3 Sempacherstrasse, Lucerne, Switzerland, Architect. An improved process and apparatus for the production of cylindrical and like bodies from concrete.

Extract from Specification.—According to the present invention the aforesaid bodies are formed by applying concrete on a core or mandrel in the form of a narrow strip which is wound helically around such core or mandrel, the concrete both during and after its actual application to the core being subjected to a considerable degree of pressure. In carrying the invention into effect the application of the concrete upon the aforesaid core is effected by means of an endless band or belt to which the concrete is supplied and by which it is applied to the core. The core is of such construction that it may, after the formation of the hollow body, be removed. Apparatus embodying the invention, whilst capable of construction in various forms, may be broadly stated to comprise the application of concrete or mortar under pressure to a core, the means preferably used comprising an endless band or belt supported and driven in any suitable manner, means being provided whereby the tension of the band may be adjusted so as to subject the concrete to considerable pressure as aforesaid as it is applied to the core. The concrete may either be supplied to the band by hand or automatically, and the necessary adjustments of the band and other parts may also be either performed by hand or automatically. Provision is made whereby longitudinal, and, if desired, helical wire reinforcements may be applied.

No. 26557.—9th September, 1909.—CHARLES EDWIN HIBBERD, of 47 Victoria Street, Westminster, London, S.W., England, Director. Improvements in and relating to coin-freed mechanism.

Extract from Specification.—An important part of the invention is the mechanism by which the inserted coin is controlled so that, upon the movement of the operating handle, the desired movement is given to the commodity-controlling means. This mechanism may be applied to electricity, gas, or other meters, or to any coin-freed mechanism, and consists of a pair of vertical leaves or plates pivoted together, and adapted when closed to permit the insertion of the coin between them, and by suitable projections on the insides of the leaves to arrest the coin in a predetermined position therein. When adapted for taking any of a series of different-valued coins, each different kind is arrested in a different predetermined position within the coin-holder. The leaves are adapted to be rotated by the operating handle until one of them is stopped by the engagement of the coin with a stop, the movement of this leaf being communicated to the commodity-controlling means. A further movement of the handle moves the other leaf forward and ejects the coin. A further important feature of this invention lies in the arrangement, when applied to an electricity-meter, of the means for controlling the switch and the means for producing a dimming effect upon the light or lights prior to the cut-off of the current, as a warning to the consumer.

No. 26558.—9th September, 1909.—JOHN RICHARD WILLIAMS, Consulting Metallurgist, HENRY WENTWORTH BRADLEY, Engineer, and BENJAMIN BRADLEY, Gentleman, all of The Woods, Grenoside, Sheffield, York, England. Improvements in obtaining zinc and [or] copper from complex ores or the like and in electrolytic cells especially applicable thereto.

Claims.—(1.) A process for the separation of zinc and [or] copper from silicate containing ores, consisting in subjecting the same to the action of a very dilute solution of sulphuric acid, substantially as described. (2.) A process for the separation of zinc and [or] copper from ores, consisting in subjecting the same to the action of a slightly acid solution of zinc and [or] copper sulphate, preferably of low concentration but of such strength that substantially the zinc or copper, or zinc and copper, principally dissolve, substantially as described. . . . (5.) An electrolytic cell particularly applicable to the process claimed in claim 2, comprising readily removable electrodes and spacing-means with or without twice as many anodes as cathodes and with or without anode-protecting shields, substantially as and for the purposes described. . .

[NOTE.—Here follow three other claims.]

(Specification, 12s. 6d.)

No. 26580.—14th December, 1908.—JAMES LOUDON BUCHANAN, of “Craigard,” Queen’s Park Parade, Northampton, England, Technical Chemist. An improved manufacture of soap.

[NOTE.—This is an application under the International and Intercolonial Arrangements, the date given being the official date of the application in Great Britain.]

Extract from Specification.—The main feature of my invention is the blending of a suitable soda soap or soaps made by any of the usual and known processes (preferably one mainly composed of cocoanut-oil soap) with a potash salt or soap made by combining or saponifying resin or colophony with any suitable potash salt, such as potassium hydrate or potassium carbonate.

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

No. 26591.—15th September, 1909.—ARTHUR YANCEY, a Mechanical Engineer, and a citizen of the United States of America, residing at Biloxi, Harrison, Mississippi, whose post-office address is 155 Benachi Avenue, Biloxi, Mississippi. Method and apparatus for shucking crustacea.

Claims.—(1.) The method of separating the meaty matter from the shell of crustacea, which consists in denuding the body portion of its back shell and appendages; in dividing the portion to be shucked, on a line transversely of the lobes or cells; in securing the shell portion on a suitable support which will permit the free escape of said meaty matter; and finally creating a removing force directed substantially in alignment with the lobes or cells for removing said meaty matter while restraining the shell. . . (5.) Apparatus for shucking crustacea characterized in that the shell of the crustacea is held against displacement on a mechanical support while the meaty matter is removed by a force disposed substantially in alignment with the disposition of the lobes or cells of the fish. . . .

[NOTE.—Here follow eleven other claims.]

(Specification, 14s.)

No. 26592.—15th September, 1909.—EDWIN LLEWELLYN HOLLY, of Katanning, Western Australia, Farmer, and ALFRED ERNEST RADFORD, of Bermuda, Broomehill, Western Australia, Farmer. Collapsible transport crate.

Claim.—A transport crate of the collapsible character described, having its sides as a, and its ends as b, hinged at a1 and b1, said sides having hinged extensions or leaves as d, which when brought together form the top of the crate, said crate being adapted to be locked by a pin as e, either when used as a crate as seen in Fig. 2, or when as folded up as seen in Fig. 3, all substantially as and for the purposes herein set forth, and as illustrated in the drawings.

Claims.—(1.) Means for use in sowing seeds, comprised by a trough formed of side members constructed and hinged together in such a manner as to form a closed angular bottom when opened on their hinges, and to provide a slot or opening between their bottom edges when closed together on their hinges, in combination with a flat board or plate formed with notches in its edges, adapted to be secured to the inside surface of one of the trough members, and to extend along the opening formed between the bottoms of such members when they are closed together, substantially as specified. (2.) The improved means for use in sowing vegetable and other seeds, constructed and operated substantially as described and explained, and as illustrated in the drawings.
