No. 14484.—21st January, 1902.—JOHN FREDERICK ROSE, of Takaka, Nelson, New Zealand, Farmer. A protection for river-banks, groins, piers, dams, approaches to bridges, flooring of watercourses, and all places requiring defence from the scouring action of water.

Extract from Specification.—The mode of construction is as follows: A strip of netting (of the length to be determined by the circumstances, and of such width as may be convenient for the placing of the mattress in position) shall be laid upon the site of the protective work, or upon a platform adjacent thereto: this may be known as the floor of the mattress. Rows of wires, for the purpose of securing the top of the mattress to the floor, and also to prevent “bagging,” shall be inserted and secured by taking one turn (about the middle of the wire) around a mesh, and giving the ends two or three twists, then leaving the ends projecting upright for securing in a similar manner to the top of the mattress. These wires must be at intervals of not more than 9 in. apart, and not more than 2 ft. between the rows. Upon the floor the loading or filling of stones shall be laid to the thickness required, which it is recommended should be about 6 in., but may be varied as circumstances require. Another strip of netting similar to the floor, and which may be known as the top, shall then be placed over the loading or filling, and the sides and ends of the top and floor securely laced together with wire, at the same time securing the top with the wires left to prevent “bagging.” When sufficient mattress has been constructed to hang as a protecting apron in front of the river-bank, groin, pier, or other position to be protected, in addition to permitting of a certain length lying on the bed of the river, watercourse, or pond over and beyond the bottom or toe of the river-bank, groin, pier, or other position to be protected (such additional length to be determined by the amount of scour or underwashing anticipated), then the mattress shall be lowered into position by inclining the platform, or by any other means, the top end of the mattress being securely made fast to the top of the river-bank, groin, pier, &c.

This claim is made with the full knowledge that wire and wire netting have already been used and patented in connection with river-protection, and my claim is made only in connection with the mode or application of wire netting as above specified.

Claim.—The making and using of the mattress, as described in the specification, loaded with stones or other suitable filling, for the protection of river-banks, groins, piers, dams, and other places subject to the scouring action of water. (Specification, 2s. 3d.)

No. 14518.—13th February, 1902.—ALEXANDER STANLEY ELMORE, of 4, Bishopsgate Street Within, London, England, Electro-metallurgist. Improvements in the process and apparatus for separating mineral substances by the selective action of oil.

Claims.—(1.) In processes for separating minerals by the selective action of oil, the addition of a small quantity of acid to the oil or water employed in the process, or to both, substantially as and for the purposes set forth. (2.) Apparatus for separating minerals by the selective action of oils, comprising a trough containing a shaft carrying inclined blades adapted to revolve within the trough, a settling-tank partitioned at the top, and a centrifugal machine adapted to revolve within a casing, constructed and operating substantially as described. (3.) Apparatus for effecting separation of minerals by the selective action of oils and like substances, comprising a mixer of the oil with the aqueous pulp of pulverised mineral, an incline for downflow of the mixture having steps or baffles, an endless apron, means of distributing oil over it, and means of causing it to travel in a direction opposite to the said downflow, a conical revolving sieve adapted to receive the discharge from the incline, a nozzle for delivering a shower of water over one side of the sieve, and two launders adapted to remove the matters that pass through and the matters that are washed over the sieve respectively, substantially as described. (4.) The combination of a stepped incline for downflow of the mixed pulp and oil with a travelling apron provided with a distributor of oil over its surface, substantially as described. (5.) The combination of a conical revolving sieve, a distributor of a water-shower over part of the sieve, a launder adapted to lead off the matters washed over the sieve, and a launder lined with blanket adapted to lead off the matters that pass through the sieve, substantially as described. (Specification, 6s.; drawings, 2s.)

No. 14587.—6th March, 1902.—JAMES COUSTON, of Perth, Western Australia, Engineer and Contractor, and WILLIAM PORRITT, of Perth aforesaid, Engineer and Contractor. Improved method for jointing iron plates used in the manufacture of pipes and in connecting plates used for any other purpose.
