(3) The method of making artificial fuel comprising the mixing and heating together of coaldust and a magnesite cement (with or without chalk) in a finely divided condition, mixing and heating together of oil specially treated as described and water (with or without lime), and the mixing-together of the resultant masses, substantially as set forth. (4.) The method of making artificial fuel which comprises the mixing and heating of coaldust and a magnesite cement (with or without chalk) in a finely divided condition, the separate mixing and heating of oil which has been previously subjected to a sulphurising process and water (with or without lime), and the mixing-together of the resultant masses, substantially as and for the purposes set forth. (5.) The method of making artificial fuel which comprises the mixing and heating of coaldust and a magnesite cement (with or without chalk) in a finely divided condition, the separate mixing and heating of oil which has been previously treated with chloride of sulphur and water (with or without lime), and the mixing-together of the resultant masses, substantially as and for the purposes set forth. (6.) The method of making artificial fuel which comprises the mixing and heating of coaldust and the magnesite cement known as petrifite (with or without chalk) in a finely divided condition, the separate mixing and heating of a petroleum oil which has been subjected to the action of chloride of sulphur and water (either with or without lime), and the mixing-together of the resultant masses, substantially as and for the purposes set forth. (7.) In the manufacture of artificial fuel, the employment of oil which has been specially treated as aforesaid, otherwise than by oxidizing it, previous to its incorporation with any of the other components of the fuel, substantially as and for the purposes set forth. (8.) In the manufacture of artificial fuel, the employment of oil which has been specially treated with chloride of sulphur previous to its incorporation with any of the other components of the fuel, substantially as and for the purposes set forth.

No. 21518.—9th October, 1905.—JAMES TEMPLE CLARK, of 189 St. James Street, Montreal, Quebec, Canada, Inventor. Improvements in automatic nut-locks.

[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.—My invention relates to automatic nut-locks, and consists essentially of a washer stamped from sheet metal, preferably spring steel, and having a plurality of fingers cut from its surface as described.

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

No. 21570.—30th July, 1906.—JOHN TURNBULL, of Waikaka, New Zealand, Farmer; and ROBERT LYALL CHRISTIE, of Gore, New Zealand, Engineer. Poison-laying machine for rabbits.*

Claims.—(1.) In a poison-laying machine, the combination of a cutting-blade like a draining-cutter for forming a narrow and deep furrow to adjustable depth with a poison-feeding device for feeding poisoned food into the said furrow just formed, all substantially as shown on the drawing, and as described and as explained. (2.) In combination with a cutting plough-share for cutting a narrow and deep furrow, a reciprocating-motion feed self tapping to ensure even delivery, said motion being capable of being put in or out of gear, all substantially as set forth.

No. 21592.—4th August, 1906.—PEREGRINE ELLIOTT GLOUCESTER CUMBERLAND, of 85 Barkly Street, St. Kilda, Melbourne, Victoria, Australia, Inventor. An improved method of preventing the corrosion and decomposition of metals immersed in water or other liquids due to electro-galvanic action.*

Extract from Specification.—In carrying my invention into effect the metal or metals now subjected to corrosion and decomposition by electro-chemical action are connected to the negative pole of a dynamo or other source of electric power. The other pole of this dynamo or source of electric power is connected to a metal plate or plates (preferably of iron) which are immersed in the water or other liquid, but insulated from the metals to be protected except through the medium of the said liquid. When the current generated in the dynamo or other source of electric power is equal to or of higher E.M.F. than that caused by the differences of potential between the metals to be protected, it is found that the electro-chemical action ceases between the metals connected to the negative pole, and these metals are brought into parallel with one another instead of opposed electrically, and consequently no corrosion or decomposition takes place while the corrosion and decomposition is confined to the auxiliary plate or plates connected to the positive pole of the dynamo or other source of electric power.

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

No. 21642.—16th August, 1906.—JAMES FERGUSSON, of Murray Street, Gawler, South Australia, Machinist (assignee of Herbert Richard Edmands, Mining Engineer, and Samuel Frederick Gidney, Mill-manager, both of Menzies, Western Australia). Improvements in filter-press plates.*

Claims.—(1.) In the manufacture of filter-press plates, the employment of a sheet or sheets of wire screening in combination with a sheet or sheets of metal (preferably perforated), all attached to a rigid rim as a means of supporting the filter-cloth or other filtering-material, substantially as described. (2.) A filter-press plate having a rigid rim to which are attached sheets of wire screening or perforated metal, substantially as described. (3.) A filter-press plate having a centre formed of two thicknesses of wire screening, one on either side of a thin sheet of metal (preferably perforated), all secured within a rigid rim provided with the usual channels, ports, and arms, substantially as described. (4.) A filter-press plate comprising a centre formed of a combination of sheets of wire screening and metal (preferably perforated), a rigid rim provided with the usual channels, ports, and arms, and having in addition its inner portion cut or formed into a ledge, in combination with fastening strips secured to the said ledge and holding the said centre in position, substantially as described.
