[NOTE.—Here follow four other claims.]

No. 29526.—16th June, 1911.—JOHN WILSON, of Auckland, New Zealand, Cement-maker. Improved apparatus for use in building concrete structures.

Extract from Specification.—According hereto, studs or stanchions of L-shaped section, intended to be permanently located during the construction of a rectangular building, are employed at each inside corner of the wall. Between these stanchions are a series of superposed shutters forming the inside of the mould, and so arranged that the lowest shutter, after a course of concrete has been filled in, can be removed and fixed above the others. A series of superposed transposable shutters, connected by bolts to the stanchions, is also employed for the outside wall of the mould. In many cases corner stanchions only will be required, but for long walls intermediate stanchions should be used. In moulding a curved wall the stanchions are curved on their outer and inner faces, the edges being bevelled at each side, and the shutters of the desired radius.

No. 29565.—18th May, 1911.—THOMAS EDWARDS, of Webster Street, Ballarat, Victoria, Australia, Metallurgist. Improvements in tilting calcining or roasting furnaces.

Claims.—(1.) A tilting furnace provided with a working-hearth, with a flue conveying gases directly over it, a separate flue above the working-hearth and another separate flue below such hearth, a chamber connecting the upper and lower flues at the feed-end of the furnace, and dampers for closing the communication between said flues through said chamber, while another damper permits of the opening of the working-hearth flue to and the cutting-off of same from said lower flue, the whole in combination with a chamber at the delivery-end of the furnace, with which the upper and lower flues communicate, and which is provided with a damper to open and close communication between said flues at such end, the upper end of each of said end chambers being provided with passages leading to a bustle-pipe or outlet-flue, and being provided with a damper to open and close the communication therewith, all substantially as and for the purpose specified.

No. 29591.—23rd May, 1911.—ARTHUR JAMES BILLOWS, of 59 Queen Street, Melbourne, Victoria, Australia, Manufacturing Chemist. Improvements in or relating to the aeration of liquids.

Claims.—(1.) Apparatus for the aeration of liquids adapted for aerating and bottling, for aerating and draught-supply, or for both purposes simultaneously, substantially as described. (2.) Apparatus for the aeration of liquids provided with an expansion-chamber through which the gas-supply is delivered to the aerating-chamber, communication between the said chambers being established mechanically for the passage of the gas and automatically when an excess of the aerated liquid accumulates in the aerating-chamber to permit such excess to escape into the expansion-chamber, substantially as described. (3.) In apparatus for the aeration of liquids, the arrangement of a bottle-carrier bottle-head, and means for shifting, substantially as described. (4.) An apparatus for the aeration of liquids adapted to fill internally stoppered bottles or bottles closed by a cork, a screw stopper, or a swing stopper in the manner substantially as described. (5.) An apparatus for the aeration of liquid constructed and operating substantially as described, with reference to the drawings.

(Specification, 12s. 9d.)

No. 29594.—23rd May, 1911.—W. R. SYKES INTERLOCKING SIGNAL COMPANY LIMITED, JOSEPH CHARLES SYKES, Director and Manager, REUBEN WILLIAM TARRANT, Electrical Engineer, all of 26 Voltaire Road, Clapham, London S.W., England. and MCKENZIE AND HOLLAND, LIMITED, of 58 Victoria Street, Westminster aforesaid, and Melbourne, Victoria, Australia, Railway-signal Engineers. Improvements in railway-rail contacts.

Extracts from Specification.—This invention relates to an improved construction of railway-rail-contact device—that is to say, a device whereby the passage of a train or vehicle over a predetermined point in the track is caused to actuate an electric switch serving to control, say, the working of a signal or the like whose operation is to be co-ordinated automatically with the movement of the traffic. . . . For this purpose the downward movement of the rail is magnified by means of a lever whose return movement under the influence of gravity (or some other constant force) is made to transmit motion, preferably again magnified in extent, through the medium of a pneumatic column, the whole or any desired part of the motion thus transmitted being ultimately utilized in the electric switch as required.

(Specification, 8s. 9d.)

[NOTE.—The above extracts from the specification are inserted in place of the claims.]

No. 29596.—23rd May, 1911.—HENRY SELLY HELE-SHAW, Fellow of the Royal Society, and FRANCIS LEIGH MARTINEAU, Member of the Institution of Mechanical Engineers, both of No. 64 Victoria Street, London S.W., England. Improvements in pumps and motors.

Extract from Specification.—Among the more important features of the invention is the employment of cap-pistons in combination with rollers or slipper carried by them and operating in conjunction with the particular construction or stroke varying ring or drum having its slipper or roller paths arranged on either side of the cylinders, said varying ring being of enclosed form whereby the working-parts of the apparatus are automatically and effectively lubricated, although the outer casing is empty, and the loss due to the usual churning of oil in the case is entirely eliminated. The construction of the central valve and its connections of the form shown is also of importance, said valve having a channel in its diaphragm for establishing a circulation of oil for lubricating between the valve and the cylinder-body, and a suitable oil-reservoir is provided, into which oil leads and from which excess of oil is conducted by centrifugal force to supply the inside of the rotating enclosed stroke-varying ring.

No. 29607.—25th May, 1911.—PETER MURPHY, of 11 Shepherd Street, Sydney, New South Wales, Australia, Sheet-metal Worker. Improved means for controlling the gas and water supply to gas-fired water-heaters.

Extract from Specification.—According to this invention, one end of a rod is so connected to the external portion of the spindle of a high-pressure valve in the water-supply conductor that on the opening of the water-valve the free end of said rod is lifted out of locking engagement, with a handle (preferably a plate of quadrant form) connected to the spindle of the gas-supply valve whereby the latter valve may be opened, in which position the free end of the rod prevents the closing of the water-valve without first closing the gas-valve. And for controlling the water-supply to the heater a tap or valve of ordinary low-pressure type is used, positioned intermediate of the before-mentioned high-pressure valve and the heater, said tap or valve being provided with a by-pass to prevent any possibility of the flow of water to the heater being entirely cut off when the gas and water valves are open and the heater in use.
