No. 7

No. 25319.—9th December, 1908.—GEORGE EDWARD WHITE, Cheesemaker, ROWLAND PREEDY BAKER, Dairy-factory Manager, and FREDERICK JOHN JACKSON, Plumber, all of Maniaia, New Zealand. Improved means for use in measuring and delivering predetermined quantities of liquids.

Extract from Specification.—The means designed consist of a receiving-tank, into which the skim-milk is run, and which is provided with a suitable outlet. Within the tank is suspended a device carrying an electric switch of suitable design, and adapted to be operated by the rising of a float arranged beneath it. This switch device is suspended within the tank in such a manner that it may be adjusted to any height therein. It is arranged in circuit with an electric alarm, so that upon the level of the liquid in the tank rising to the height necessary to press the float upwards on to the switch the switch will be closed, and the alarm caused to sound. Thus the attendant will be warned that the amount of milk to be delivered has been run into the tank, so that the supply may be cut off.

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

No. 25321.—7th December, 1908.—BERTHOLD HERMAN NEES, of Dunedin, New Zealand, Manager Furniture-factory. Improved metal couplings for wooden frames.

Claims.—(1.) In metal couplings for coupling up wooden framings, in combination, the single part bolted to the post, with the double or jaw part made separate in two pieces, and furnished with internal lugs formed in one with each, for easy fitting and tightening up when together, all substantially as described and as explained, and as illustrated in the drawing. (2.) In metal couplings for wooden framings, the single part formed with a rest on which to rest the double part, which is made in two pieces capable of being tightened up or loosened as needed, all substantially as set forth.

(Specification, 2s. ; drawing, 1s.)

No. 25331.—20th March, 1908.—CARL ALBRECHT BAECHLER, of 5 Kollikerstrasse, Zurich, Switzerland, Dairy Engineer. Improvements in the manufacture of casein.

[NOTE.—This is an application under section 106 of the Act, the date given being the official date of the application in Great Britain.]

Claims.—(1.) The manufacture of casein by first adding to the milk, if necessary, a substance which enhances the tendency of the casein to coagulate, then adding a coagulating ferment, preceded by, accompanied by, or followed by a material which has the effect of causing coagulated casein to shrink together; then, at the moment when the coagulation is first perceived, rapidly agitating the whole until the casein is in a finely divided condition; then, while still agitating, heating and cooling the whole successively, and finally separating and drying the casein.

[NOTE.—Here follow five other claims.]

(Specification, 4s.)

No. 25333.—8th December, 1908.—WALLACE CARR, of Alexandra, Miner, and ARTHUR E. SPOONER, of Alexandra South, Engineer, both in New Zealand. Improved current motor or power-developer.

Extract from Specification.—The object of this invention is to obtain as much power as possible from running streams by wheels of a make similar to that of screw propellers, but as the water strikes the vanes of such wheels in a slanting direction, we counteract this as much as possible by diverging the incoming stream in the opposite directions, thus converting the first wheel the stream encounters into a turbine by the said diverted water striking the vanes more squarely. As the well-known action of water driving such wheels is to give it a swirling or rotary movement, the next wheel has its vanes formed in the opposite direction, so as again to give it somewhat the action of a turbine, and so forth for as many wheels as are employed.

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

No. 25337.—17th December, 1908.—DARCY GILBERD, Contractor, and GATLAND GILBERD, Contractor, both of Henderson, Auckland, New Zealand. Improvements in friction-clutch appliances.

Claim.—The combination in friction-clutch apparatus of the striking-rollers Y, cam or other projection in connection with the striking-bar L, the screw N, and frame, all substantially as set forth.

No. 25345.—15th December, 1908.—WILLIAM L. IMLAY, of Conestoga, Pennsylvania, United States of America, Gentleman. Process of extracting precious metals from their ores.

Claims.—(1.) The process of treating ores which consists in pulverising said ores while they are subjected to a solution capable of dissolving the contained values, and alternately heating and cooling said ore and solution while being exposed to light and air and under agitation. (2.) The process of treating ores which consists in subjecting them to the action of a cyanide solution, and alternately heating, cooling, and agitating said ore and solution while exposed to light and air. (3.) The process of treating ores which consists in continuously conveying them through successive bodies of cyanide solution, and alternately heating and cooling and agitating said ore and solution while exposed to the action of light and air. (4.) The process of treating ores which consists in acting upon them by a solution of cyanide while being subjected to rubbing or scouring conducted under changes in temperature and to the action of light and air. (5.) The process of treating ores which consists in conveying the pulverised ores in the presence of a solution capable of dissolving therein contained values over a series of lixiviators where said ore and solution are alternately heated, cooled, agitated, and scoured while exposed to the action of air. (6.) The process of treating ores which consists in subjecting the ore to the action of a solution capable of dissolving the values therein contained, amalgamating said mixture of ore and solution, then conveying said mixture over a lixiviator where same is alternately heated, cooled, and agitated while exposed to the action of light and air, then separating said solution from said ore, and then recovering the values. (7.) The process of treating ores which consists in subjecting them to the action of a solution capable of dissolving their values, while being subjected to rubbing or scouring conducted under alternately rising and falling temperature. (8.) The process of treating ores which consists in subjecting them to the action of a value-dissolving solvent, raising and lowering the temperature of said ore and solvent by friction caused by allowing the ore to fall, rubbing and scouring it. (9.) The process of treating ores which consists in subjecting them to the action of a value-dissolving solvent and alternately heating and cooling the ore and solvent while exposed to light and air and under frictional agitation by causing the ore to fall, by stirring, by rubbing, and by scouring. (10.) The process of treating ores which consists in acting upon them by a solution of cyanide while being subjected to the action of friction by causing the ore to fall, by agitating it, and by scouring, while exposed to the action of air.

No. 25346.—15th December, 1908.—HUBERT ELWELL SMITH, of 52 Frederick Street, Edinburgh, Scotland, Electrical Engineer. Improvements in and relating to carburetters.

Claims.—(1.) A carburetter comprising two closely fitting chambers, each composed of a series of enlarged portions joined by relatively constricted channels, substantially as described. (2.) A carburetter comprising two closely fitting chambers, each having a series of alternate enlargements and constrictions, immersed in liquid contained in an outer casing, substantially as described. (3.) A carburetter according to claim 2 in which the chambers are split into two halves, so as to allow of more ready access of the surrounding liquid to the interior. (4.) A carburetter according to claim 1 in which the enlargements are approximately spherical, or doubly conical, substantially as described.
