No 15654.—19th November, 1902.—CHARLES PEYRON DE LAJARD, of 7, Rue Theodore Aubanel, Avignon, France, Director of the Compagnie Générale des Moteurs Maritimes. Device for the utilisation of the power derived from the waves of the sea.

Claim.—Device for the utilisation of the power derived from the waves of the sea, comprising, in combination with a main frame running on wheels, a fly-wheel for the transmission of the power to working machines, axles rotated by the movement of the surface of the sea, a gearing connecting the axle of the fly-wheel with said axles, ratchet wheels on said axles, forks embracing the ratchet wheels, pawls linked to the forks and engaging with the ratchet wheels, racks at the closed ends of the forks, spur wheels engaging with said racks, pinions engaging with said spur wheels, racks engaging with the pinions, shifting rods linked to the outer ends of said pinion-racks, levers linked with the upper end to the outer end of the shifting rods, floaters coupled in pairs by rigid frames, a cross-bar fixed on the centre of the side bars of said floater-frame, one end of which is rigidly connected with the lower end of one of the levers of the shifting rods, connecting-rods rigidly fixed to the ends of two of the cross-bars, a rigid frame for the floaters adjustably connected with the main frame by a vertical axle, an axle rotatably supported in the ends of the frame carrying the connecting-bars of each set of two pairs of floaters and the ends of the levers of four of the shifting rods, substantially as described and shown and for the purpose set forth.

No. 15657.—20th November, 1902.—LUCY ADAMSON, of Waihao Forks, New Zealand, Employed in Domestic Duties. Improved apparatus for employment in connection with the collection of rain-water from the roofs of houses.

Claims.—(1.) Apparatus for the purpose indicated, consisting of the combination and arrangement of parts, substantially as herein specified. (2.)

No. 15660.—19th November, 1902.—HUNTER HENRY MURDOCH, of Hastings, Hawke’s Bay, New Zealand, Patent Agent. Improvements in set-squares for use in mechanical and other drawing.

Claims.—(1.) The improvements in set-squares described, and illustrated in Figs. 1 to 10 (both inclusive) of the drawings—that is to say, the formation in a set-square of a slot or slots, in which slot or in one or other of such slots is inserted a sliding stop of any one of the kinds described, the said stop and set-square being arranged and operated relatively to and with each other, essentially as and for the purpose described. (2.) The sliding stops described with reference to Figs. 2 and 3 of the drawings—that is to say, a series of graduated stops, each of which consists of an oblong plate of wood, ebonite, or other suitable material, of such width as to fit and slide easily in the slot or either of the slots in the aforesaid set-squares, but of less length than such slot or slots, the length of each stop being such as, when it is used in combination with either of the set-squares, to enable the draughtsman to draw section or other lines of the requisite distance apart, essentially as described. (3.) The adjustable sliding stop described, and illustrated in Figs. 4, 5, and 6 of the drawings—that is to say, an oblong stop furnished with a set-screw, the lower part of the milled head of which enters the slot in either of set-squares aforesaid, the said sliding stop and set-square being arranged and operated relatively to and with each other, essentially as and for the purpose described. (4.) The adjustable sliding stop described, and illustrated in Figs. 7, 8, and 9 of the drawings—that is to say, a stop consisting of two oblong plates arranged one upon the other, the upper plate having on its under-side a longitudinal dovetail rib which slides as required in a correspondingly formed longitudinal rebate in the upper side of the lower plate, the said plates being clamped together as required by means of a screw fixed in the said lower plate, which screw passes through a longitudinal slot formed in the said upper plate and carries a milled nut, the said upper plate having at one end a transverse rib which enters the slot in either of the set-squares aforesaid, the sliding adjustable stop thus constructed and the set-square being arranged and operated relatively to and with each other, essentially as and for the purpose described.

No. 15664.—18th November, 1902.—JOHN ROGER, of 6, Coningsby Road, Finsbury Park, London, England, late a Tea-planter in Ceylon, and MONTAGUE KELWAY BAMBER, of the Laboratory, Hyde Park Corner, Cinnamon Gardens, Colombo, Ceylon, Agricultural Chemist. An improved process for obtaining a soluble extract of tea.

Claims.—(1.) The process of obtaining from the leaf of the tea-plant a soluble extract or extracts containing the tannin, theine, and other valuable principles of the leaf, and possessing the peculiar aroma, flavour, pungency, and invigorating properties of the ordinary tea of commerce, characterized by firstly obtaining such principles in solution, and then separating such principles from the solvent fluid and obtaining the same as an extract or extracts in the form of dry powder or thick fluid by the successive procedures of heating the fluid sufficiently to keep soluble matters in solution, separating by centrifugal action foreign matters from the hot fluid, refrigerating the clear fluid sufficiently to throw the tannin, theine, and other valuable principles of the tea out of solution, separating by centrifugal action from the refrigerated fluid such of such principles as are specifically heavier than the fluid in paste-like or caky mass, reducing such mass to dryness, evaporating the fluid down to any required degree of concentration, refrigerating the concentrated fluid sufficiently to throw the remaining valuable principles out of solution, separating by centrifugal action such principles from such refrigerated concentrated liquid in paste-like or caky mass, reducing such mass to dryness, repeating such concentrating, refrigerating, separating, and drying processes if necessary, and evaporating the resultant fluid, if containing any valuable principles, down to a thick fluid condition or to dryness, as set forth. (2.) In obtaining from the leaf of the tea-plant an extract containing the valuable principles thereof, the process consisting in and characterized by obtaining such principles in solution, and separating such principles from the solvent fluid—after freeing the latter from foreign matters by heating the fluid and subjecting it while hot to the action of a cen-
