aforesaid, Engineer. Method and apparatus for separating oily or similar impurities from water.

Claims.—(1.) The method of separating oily and similar parts from water containing the same, consisting in subjecting the water, with the addition thereto, as required, of a small regulated quantity of conducting-liquid, to the action of electric current between metallic electrodes. (2.) In a method as firstly claimed, the employment of a tank a which may have an inlet compartment b and is provided with metallic electrodes d, which the oily water passes in a circuitous path, said water being admitted at one end of the tank by a valve j, which is regulated by hand or automatically by the current, while the conducting-liquid is admitted by a valve r, which may also be regulated by hand or automatically by the current, the water passing off by an overflow h at the other end of the tank. (3.) Separating oily and similar parts from water containing the same by the method firstly claimed, and then removing the separated oily particles by filtration or settling.

No. 15857.—8th January, 1903.—WALTER CUTTEN, of Dunedin, New Zealand, Consulting Engineer. Improved form of compound winches, especially for dredges.

Claims.—(1.) In compound winches, especially the sort used for the work that is needed on dredges and suchlike, the form and general arrangement of the winch and the gearing thereof whereby the main shaft is arranged to be capable of being revolved in either direction, the said shaft having some barrels geared to same singly, so that said barrels are only capable of revolving in the same direction as the main shaft, and also having some barrels geared to same doubly, so that said barrels are capable of revolving in either direction, no matter which way the main shaft is revolving, all substantially as set forth and for the purposes indicated. (2.) In compound winches, especially that class of winch used for dredges, the form and general arrangement of the winch and its gearing to the barrels so that while all the barrels can remain at rest with their brakes on, some of the said barrels need the reversing of the main shaft when they need reversing, while others are provided with double clutches so as to be independent of the direction of revolution of the main shaft for their working in either direction, substantially as set forth and as shown on the drawing and described and explained.

No. 15863.—13th January, 1903.—HANS CHRISTENSEN, of 28, Godthaabsvej, Copenhagen, Denmark, Mill-builder. Improvements in matches and machinery for their manufacture.

Claims.—(1.) Rectangular or wedge-shaped matches the head ends of which are cut in on all four sides, so that the composition will not protrude beyond the sides of the match. (2.) In the manufacture of splints for the match-bodies referred to in claim 1, a vertically movable carriage for the knives, lancets, or gouges, substantially as described. (3.) In the manufacture of splints for the match-bodies referred to in claim 1, the use of knives made up of a number of short knives and gouges arranged either in a straight or zig-zag line, the gouges being carried by the short knives, substantially as described. (4.) In the manufacture of splints for the match-bodies referred to in claim 1, the use of gouges with inclined or rounded corners, which, whilst forming a groove in the underside of the splint, cut away the projection that remains on the surface of the log from the cut made by the gouges, that cut a groove on the inner side of the splint, substantially as described. (5.) In the manufacture of splints for the match-bodies referred to in claim 1, the use of knives made up of short knife-pieces whose ends are sharpened in such a way as to form gouges, substantially as described. (6.) In the manufacture of splints for the match-bodies referred to in claim 1, a stationary double holder for the gouges and lancets having two cross-bars, one of which carries gouges and the other the lancets, and which are placed at such a distance apart that the wood can pass between them, substantially as described. (7.) In the manufacture of splints for matches, the arrangement in the machines for cutting the splints of gouges and lancets movable in blocks that are carried in holes in a stationary supporting-bar and urged by springs towards the surface of the log, substantially as described. (8.) In the manufacture of splints for matches, the arrangement in the splint-cutting machines of holders which, whilst they are moved regularly during the operation of the machine towards the axis of the log of wood, are constructed in such a way that they are forced automatically towards the surface of the log, from which they are held by means of adjustable distance-blocks, substantially as described. (9.) In the manufacture of the match-bodies referred to in claim 1, the use in the chopping-off machines of gouges arranged to cut in the third side of the head ends of the matches, substantially as described. (10.) In the manufacture of the match-bodies as referred to in claim 1, the use in the chopping-off machine of a horizontally moving compound knife, which at the same time that it cuts off the match-bodies cuts in the fourth side of the match-heads, substantially as described. (11.) In machines for manufacturing wedge-shaped matches, as referred to in claim 1, the arrangement of a storage-box which moves one-match length to the side each time it moves forward at every stroke of the knives, substantially as described.
