No. 20454. — 14th December, 1905. — THE CHARTERED PATENTS COMPANY, LIMITED, a corporation of the State of New York, United States of America, of 27, William Street, New York City, New York aforesaid (assignees of John Robert Pearson, of 203, Eighth Street, Brooklyn, New York aforesaid, and Gustave Alfred Pearson, of 217, Fifth Avenue, Brooklyn aforesaid, Engineer). Improvements in type casting and setting machines.

Extract from Specification.—The machine is direct-acting—that is, the depression of a key causes the corresponding type to be cast without employing a previously prepared strip or analogous device. The types are produced in accordance with the unit system—self-spacing—and delivered successively in word-chambers in a magazine, from which the words are transferred to a galley, the line being justified during such transference. The machine is driven by power, and the various movements initiated through electro magnets, energised by key contacts and switchers, as permitting more rapid and direct control.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 20455. — 14th December, 1905, AKTIEBOLAGET SEPARATOR, a company existing under the laws of Sweden, and having their place of business at 8, Fleminggatan, Stockholm, Sweden, Manufacturers (assignees of Birger Ljungström, of 8, Fleminggatan, Stockholm aforesaid, Engineer). Improvements in centrifugal separating apparatus.

Claims.—(1.) In centrifugal separating-apparatus of the kind having rotating scrapers located within the bowl for the transport of the solids, the improvement, that said scrapers are cup-shaped and secured to the rotating part in such a position that relatively to a plane through the radius, and the axis of rotation they have their bottom situated deeper than their edges, in order that the catching-capacity of the scoops may be increased. (2.) In centrifugal machine, as claimed in claim 1, the improvement that the scoops are located between two rings or discs, whereby the scoops themselves may be open at the top and the bottom.
(Specification, 2s.; drawings, 2s.)

No. 20456. — 31st December, 1904. — HENRY JOSEPH RANDOLPH HEMMING, of Kent Cottage, Hither Green, Kent, and of 81, Cannon Street, and 4, Budge Row, London, England, Solicitor. Improvements in methods of and apparatus for sterilising, preserving, and aerating foods, liquids, and organic substances, and treating materials with gases.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Great Britain.]

Extract from Specification.—I enclose the liquid in a suitable receptacle, which is then closed except for two orifices which may both be situated above the surface of the liquid or the one for the ingress of the gas below the surface and the one for the egress above the surface of the liquid. Carbon-dioxide, or any other required gas or gases, is then, at a pressure, passed in at one of these orifices to drive out and displace the air in the space above the liquid, which escapes at the other. When the whole or greater part of the air has been so removed and displaced more gas is admitted under pressure, the liquid being now agitated so as to facilitate the absorption of the gas; the pressure is then relieved, to allow the air in solution to escape so that it may be driven off. For this latter operation the gas, if it is carbon-dioxide, should be used at a pressure of at least four atmospheres, preferably more, in order that the air may be displaced. Lastly, more gas is admitted under a sufficient pressure (four to ten atmospheres or more), and the liquid agitated to insure sufficient saturation to accomplish the purpose desired, and the receptacle is then sealed. But a very great economy is effected by arranging a large number of such receptacles in series, so that a comparatively small amount of gas may replace, displace, and drive out the whole or nearly the whole of the air, and I have devised a convenient form of apparatus for the purpose.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 20464. — 18th December, 1905. — LEO AUSTIN WALSH, of Remuera, Auckland, New Zealand, Engineer. Improvements in fish-hooks or artificial bait.

Claims.—(1.) In fish-hooks of the class described, a double spring to the respective members of which the hooks are connected, a rod passing longitudinally through the bend of the spring and between the members thereof, the outer end of which is connected to the fishing-line, and a cross head-piece secured to the inner end of the rod and loosely encircling the members of the spring on each side thereof, substantially as and for the purposes specified. (2.) In artificial bait of the class described, forming such bait in two halves longitudinally, hinged together at their top ends and with hooks attached to their respective bottom ends, a double spring inserted between the two halves with its respective ends secured to the halves on each side, a rod passing longitudinally through the top of the bait and the bend of the spring to the outer end of which the fishing-line is attached, and a cross head-piece secured to the inner end of the rod and loosely encircling the members of the spring on each side thereof, substantially as and for the purposes specified. (3.) The improvements in fish-hooks or artificial bait, substantially as described and explained, and as illustrated in the drawings.
