Claims.—(1.) For internal-combustion engines, means for regulating the supply of combustible fluid in proportion to the air supplied, comprising a meter for feeding the combustible fluid, working in combination with a motor-meter, through which a fraction of the air-supply is forced by the excess of the pressure of the atmosphere above the pressure in the suction-pipe of the engine. (2.) In a contrivance according to claim 1, a feeder of equal small volumes of liquid combustible, and a vapouriser which is adapted to receive the said volumes in succession. (3.) In a contrivance according to claim 2, a feeder adapted to raise from a supply-chamber a succession of small volumes of liquid and deliver them to the vapourising-chamber; and for driving the feeder, an auxiliary motor of the wet-meter type driven by a fraction of the air-supply to the engine. (4.) In a contrivance according to claims 1–3, means for regulating the fraction of the entire air-supply which is employed in operating the motor-meter. (5.) In a contrivance according to claims 2–4, a vapouriser consisting of the upper compartment of the silencer-box through the lower compartment of which the exhaust gases flow on their way to the atmosphere, the compartments being separated by a sloping plate on which is superposed another sloping plate on to the higher portion of which are dropped the successive volumes of liquid combustible. (6.) In a contrivance according to claim 5, means for reheating the exhaust gases, consisting in the provision of a supply of air to the silencer with the exhaust gases to burn the unconsumed combustible portion thereof.

No. 22803.—10th May, 1907.—NICHOLAS WALTER FROGLEY, of St. John Avenue, Mont Albert, Victoria, Australia, Contractor. Improvements in or connected with window-sashes and fastenings therefor.

Claims.—(1.) In a double-hung-sash window and connections operating vertically in the ordinary manner, a lower sash, such as (C), capable of being drawn inwards, moving pivotally on its base or lower rail of its frame out of its ordinary vertical position, and secured to rest at an angle so as to provide an air-opening between the upper and lower sashes while otherwise encased or closed at the sides, fitted, operated, and secured as and in manner before described and as illustrated. (2.) In a double-hung-sash window and connections, the twin spring side-bolts (G), (G1), (G2), (G3), secured respectively to the inner surfaces of the frame of the lower sash, and metal lined plates and holes therein in window-case for reception of such bolts for securing the sash when closed or open, arranged, fitted, and operated by hand, as and in manner before described, and as illustrated. (3.) In a double-hung-sash window and connections, the fastener or catch (F), (F1), the movable latch secured to the top rail-bar of the upper window-sash and its catchment to the window-frame, fitted as described and operated by a sash-hook as and in manner before described and as illustrated. (4.) In a double-hung-sash window and connections, the metal studs or loops (D1) attached to the upper surface of the top rail of bottom sash through which the cords are reeved to draw said cords out of alignment and frictional contact with the window-casing, fitted and operating as and in manner before described and as illustrated. (5.) As an improved double-hung-sash window and connections, the sashes operating vertically in the ordinary manner, and the lower sash capable of being drawn inwards out of its ordinary vertical position while otherwise encased or enclosed at the sides so as to provide an air-opening or ventilation between the sashes, the combination and arrangement of the several parts, connections, and fastenings, fitted and operated as and in manner before described and as illustrated.

No. 22814.—13th May, 1907,—FREDERICK CHARLES THOMPSON, of Christchurch, New Zealand, Inventor. Improved mechanism for operating venetian blinds.

Claims.—(1.) Means for actuating venetian blinds, consisting of a roller mounted longitudinally above the head-board of the blind, collars or pulleys upon the roller upon which the lifting cords of the blind are wound, a fusee upon the end of the roller, a cord having one end secured to and wound upon such fusee in an opposite direction to that in which the lifting cords are wound while its other end is made fast to a fixed point, a vertically arranged helical spring made fast to a fixed point at its lower end, and a pulley secured to the upper end of the spring and through which the cord wound on the fusee is passed before being made fast at a point above it, substantially as specified. (2.) The improved mechanism for operating venetian blinds, substantially as described and explained, and as illustrated in the drawings.

No. 22828.—16th May, 1907.—DAVID MCKENZIE, of Tennyson Street, Grey Lynn, Auckland, New Zealand. A combination ottoman, bed, and couch.

Extract from Specification.—The principles of my claim are in the back being hinged 6 in. from the inner edge A, to allow the back to fall down into the box part E, thus bringing the back to the proper height when closed up as a couch; also in the lid being hinged on the front edge of the ottoman part, and the partition put long-ways in the ottoman part, which forms a receptacle for the inner edge A of the back when closed up as a couch.

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

No. 22842.—14th May, 1907.—PARNELL RABBDGE, of Water’s Road, Neutral Bay, near Sydney, New South Wales, Australia, Electrician. An improved moist electrolyte for secondary and for primary batteries.

Claim.—In moist secondary or primary cells the improved electrolyte, consisting of an absorbent composed of suitable residual vegetable nut or seed pulp, such as copra from which the oil has been expressed, the absorbent material being saturated, while in the cell, with any suitable liquid electrolyte, such as sulphuric acid, sal-ammoniac, or caustic potash, as specified.

(Specification, 1s. 9d.)

No. 22864.—17th June, 1907.—FREDERICK CAPEL BROWN, of Komata, Auckland, New Zealand, Mine Superintendent. An improved lining for tube-mills and ball-mills and similar grinding and pulverising machines.
