reservoir. A priming-cylinder v is provided, having a priming-piston w reciprocatingly mounted therein. This priming-cylinder is arranged in line with the axis of the pulsating engine-cylinder, and its piston is formed integral with the pulsating-piston in said latter cylinder. A pipe x leads from said priming-cylinder to the reservoir, and is provided with a check-valve y that permits air to pass in one direction only—viz., into the reservoir, as indicated. The priming-cylinder is further provided with an inlet-pipe z, having a check-valve o that permits air to enter such cylinder through said inlet-pipe, but does not permit it to exhaust there-through.

No. 19182.—9th March, 1905.—THOMAS LEOPOLD WILLSON, of 188, Metcalf Street, Ottawa, Ontario, Canada, Manufacturer. Improvements in automatic gas-buoys.

Extract from Specification.—My invention relates to improvements in automatic gas-buoys, and the objects of my invention are to devise a combined buoy, gas generator, and burner, so arranged that when once charged with gas-producing material it will automatically operate for an extended period of time, purging itself of the accumulating lime; further objects are to provide convenient means for causing the operation to cease during charging, and to provide means for preventing the movement of the water compressing and rarefying the gas in the generator; and it comprises a floatation chamber of any suitable form, an acetylene-gas generator located centrally therein, an openwork support dividing the generator chamber into two portions, a valve located at the bottom of the said chamber and adapted when open to permit the entrance of the water forced therein by the hydrostatic pressure of the surrounding water, an outlet at the top of the generating-chamber, and suitable means for burning the gas generated; the various parts of the device being constructed and arranged in detail as more particularly described. The drawing shows a sectional view through the centre of my gas-buoy. It is to be understood that, although the present apparatus is described with reference to the use of calcium carbide CaC₂, other metallic carbides, such as barium carbide, may be used in place thereof.

No. 19187.—10th March, 1905.—WILLIAM DIMOCK, of Wellington, New Zealand, Manufacturer. An improved system of and means for use in cooling storage or preserving chambers.

Extract from Specification.—The invention consists, broadly, in the use of a number of large pipes arranged in parallel rows within the chamber. These pipes are closed at their ends, and are each connected at one end with a pipe leading from the bottom of an elevated brine-tank situated outside the chamber. Similar connections are made from the other ends of the large pipes to the top of the brine-tank. Extending axially through all of the pipes in turn is a pipe of smaller diameter. This pipe, as it passes through all of the large pipes, will leave an annular space between it and the inside of each large pipe. The large pipes are filled with brine from the tank, and ammonia is then introduced into one end of the central pipe. It then expands through such pipe, thereby cooling the brine surrounding it in each of the large pipes.

No. 19195.—13th March, 1905.—GEORGE WILKINSON, of Valley Heights, Blue Mountains, New South Wales, Australia, Contractor. Improvements in the manufacture of artificial stone.

Claim.—Artificial stone consisting of cement, sieved sand, and broken stone or other material such as coke or cinders incorporated together with an aqueous solution of silicate of soda and tincture of iron, substantially in the proportions and in the manner described.
(Specification, 2s. 3d.)

No. 19218.—18th March, 1905.—HAROLD IRWIN, of Fernhill, Hawke’s Bay, New Zealand. Alarms.

Claims.—(1.) An alarm comprising a case having compartments adapted to receive fire-crackers, and a holder for a combustible with which the fire-cracker fuse may be connected. (2.) An alarm, comprising a case having compartments adapted to receive fire-crackers, and an elongated holder for a combustible provided with a series of openings through which the fire-cracker fuses may be passed.

(6.) An alarm comprising a case having a series of compartments, a wall closing the case at one end of the compartments and being provided with a contracted opening into each compartment, and an elongated holder extending in proximity to the compartments and being provided with a series of openings. (7.) An alarm comprising a case having a series of compartments, a wall closing the case at one end of the compartments and being provided with a contracted opening into each compartment, an elongated holder extending in proximity to the compartments, and partitions extending from the wall between the openings. (8.) An alarm comprising a case having a series of compartments, a wall closing the case at one end of the compartments and being provided with a contracted opening into each compartment, an elongated holder extending in proximity to the compartments, and a cover extending over the openings and holder.
