No. 18982.--24th January, 1905.--JAMES PALMER CAMPBELL, of 15, Featherston Street, Wellington, New Zealand, Solicitor (nominee of Paul Martyn Lincoln, of 6830, Thomas Street, Pittsburg, Pennsylvania, United States of America, Electrical Engineer). Improvements in systems of electrical distribution.

Claims.--(1.) A system for supplying translating devices with energy from an alternating-current source through a transformer winding in which the translating devices are included in a work circuit connected to an intermediate point in, and one terminal of, the transformer winding, the other terminal of the transformer winding being connected to the source of energy, and having the grounded conductor of the source of energy connected to a point in the transformer winding located between the points in the winding to which the work circuit is connected, for the purpose set forth. (2.) A system for supplying current to alternating-current single-phase motors from a transformer winding connected to a source of energy, substantially in the manner shown in the diagram.

No. 18987.--25th January, 1905.--WILLIAM BRADY, of 1127, Folson Street, San Francisco, California, United States of America, Miner. Rock-drills.

Claims.--(1.) A drill and an internal-combustion engine having its piston-rod connected directly with the drill, a cross-head and connections through which motion is transmitted to revolve a crank-shaft and fly-wheels, said cross-head having an independent forward movement to allow the cranks to pass the centre after the blow is struck. (2.) An internal-combustion engine, a drill, the head or chuck of which is fixed to the engine piston-rod, a cross-head loosely slidable upon the drill and receiving a forward movement from the chuck in unison therewith, a crank-shaft and fly-wheels, connections between the cranks and the cross-head to revolve the shaft and wheels by the forward movement of the piston-rod, the cross-head having an independent forward movement after the blow is struck to allow the cranks to pass the centre and the fly-wheels to return the pistons and drill, and a gear and cam carried by the shaft and acting to open the exhaust-valves upon the return stroke.

No. 18992.--26th January, 1905.--WILLIAM CHALMERS FORBES, of s.s. 'Edina,' Queen's Wharf, Melbourne, Victoria, Australia, Master Mariner. Improvements in and relating to distance and course recorders for ships.

Extract from Specification.--This invention relates to that class of distance and course recorders wherein a rotator mounted in the bottom of the ship is operated by the inrush of water as the ship travels, and is particularly applicable for rotating mechanism of the character set forth in my British Patent No. 25241 of 1902. One of the disadvantages of this class of recorder is that the inlet-pipe protrudes permanently below the bottom of the ship, and cannot be removed except when in dry-dock, so that harbour dues are increased on account of the extra draught. One of the objects of this invention is to remove this difficulty by making the inlet-pipe movable, so that it may be raised when entering harbours or passing over bars or sand-banks; another is to provide a simple and reliable means for checking any inaccuracies in the steering. Briefly stated, the removable tube in which the rotator is mounted is extended through an inverted U-shaped pipe and protrudes through the ship's bottom, the mouth of said tube being shaped to form a forwardly opening inlet. The motion of the rotator is transmitted by rods and cords, &c., to a meter, and from the mechanism of same the rollers of the course-recorder are set in motion and draw the chart-ribbon along in touch with a recording-pen connected to the compass-card, and by this means records not only the actual course travelled but the distance made good towards the ship's destination, thus instituting a check against any inaccuracies in the steering. It will be observed that the whole of the operating parts are so arranged in their casing that they may be readily withdrawn therefrom, whilst valves are provided for closing the water inlet and outlet.

No. 18998.--27th January, 1905.--JACOB EMANUEL BLOOM, of New York, United States of America, temporarily of Manila, Philippine Islands, Captain Commissary, United States Army. Improvements in the process of preparing oils for edible and other purposes and preparations embodying such and for the products of such process.

Extract from Specification.--My invention, which is the result of physiological investigations, has for its object the production of an oil for edible, culinary, or other purposes which will be most readily assimilated or absorbed by the human system, and which will avoid the abnormal deposit of solid fats, and which will entail upon the digestive organs or the kidneys or absorbing tissues little or none of the work incident to the elimination or rejection of non-assimilable portions of oils or fats now provided for human consumption; and, to this end, the invention consists in so treating and compounding oils that the resulting manufactured oil, whether such be a separate entity by itself or whether it be embodied in or part of a food product, shall comprise olein, palmitin, and stearin in the approximate proportion in which said constituents are found in human fat; and with or without minute quantities of other tri-glycerides of fatty acids, or water, or flavours, or other naturally occurring ingredients found in the native oils used in the process.

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

No. 18999.--27th January, 1905.--HOWARD BUTTERS, of Lethangie, Havelock North, Hawke's Bay, New Zealand, Settler. Improved means for securing fencing-wires to standards and droppers.

Claims.--(1.) An improved means for securing fencing-wires to standards and droppers, substantially as specified and illustrated. (2.) For the purpose indicated, the employment of a wire staple, which is threaded upon fencing-wire, passed through a hole in the standard, and its ends twisted around the wire, substantially as specified. (3.) For the purpose indicated, the employment of a single wire which is bent at one end around a fencing-wire, passed through a hole in the fencing-post, and has its opposite end bent round the fencing-wire, as specified and illustrated.

No. 19002.--25th January, 1905.--AKTILBOLAGET SEPARATOR, a society incorporated under the laws of Sweden, and having its place of business at 8, Fleminggatan, Stockholm, Sweden, Manufacturers (assignees of Anders Johan Ericsson, of 8, Fleminggatan aforesaid, Engineer). Improvements relating to centrifugal separating apparatus.

Claims.--(1.) In centrifugal apparatus for the separation of solid and liquid substances, provided with a whole (not perforated) bowl-wall means for continuously removing the solid substances separated during the centrifugal process and stratified at the periphery of the bowl, said means consisting of one or more scoop-discs mounted in the bowl and of smaller diameter than the radius of the bowl, said disc or discs being pivotally arranged on spindles which, by means of gearing from a separate shaft, are moved planet-wise around the line of centre of the bowl, whereby the scoop-discs, in consequence of friction against or gearing from some centrally arranged part of the bowl, rotate around the aforesaid spindles in order that the solid substances successively caught up by the scoops during the movement of same along the periphery of the bowl may, on the rotation of the scoop-discs around their own spindles, be carried transversely
