No. 24922.—15th September, 1908.—THE FRIESE-GREENE PATENTS, LIMITED, of 64 Victoria Street, Westminster, London, England, Manufacturers (assignees of William Friese-Greene, of 203 Western Road, Brighton, Sussex, England, Photographer). Improvements in and relating to cinematographic apparatus.

Claims.—(1.) In cinematographic apparatus, a translucent screen adapted to be travelled between the film and the lens in such manner that successive exposures or projections are effected through successive colour-divisions of said translucent screen, for the purpose set forth. (2.) A translucent screen, as claimed in claim 1, divided into successive series of primary colours and adapted to be intermittently travelled simultaneously with and adjacent to the sensitised film or film provided with photographs, between each period of exposure, substantially as and for the purposes set forth. (3.) A method of reproducing animated pictures in the natural colours, consisting in effecting successive projections through successive colour-divisions of a continuously travelling translucent film or screen placed adjacent to the film, substantially as set forth. (4.) A transparency bearing a picture or a series of pictures adapted, when placed adjacent to a translucent screen coloured with successive series of primary colours and projected upon a screen, to represent objects in their natural colours. (5.) In cinematographic apparatus, the employment of two films, whereof the one is divided into successive series of primary colours, and the other is sensitised orthochromatically, or provided with photographs, whereby to receive or transmit a series of images, said films being juxtaposed and adapted to be travelled relatively to the lens, substantially as described.

No. 24954.—21st September, 1908.—JAMES EDWIN MAIN, of Christchurch, New Zealand, Engineer. An improved machine for trimming the edges of grass lawns and the like.

Claims.—(1.) The improved machine for trimming the edges of grass lawns and the like, characterized by having a fixed vertical blade attached to a running frame, and a number of rotating blades adapted to rotate in a vertical plane down and across the surface of the fixed blade from the front edge thereof, and means whereby the movement of the running wheel will actuate the rotating blades. (2.) In machines for trimming the edges of grass lawns and the like of the class referred to in claim 1, a horizontal spindle carried by the frame and geared with the running wheel, a fixed vertical blade attached to the frame and depending from one side thereof, and a number of blades secured upon the outer end of the spindle and adapted, when rotated, to pass down and across the front of the fixed blade, substantially as specified. (3.) The general arrangement, construction, and combination of parts in my improved machine for trimming the edges of grass lawns and the like, substantially as described and explained, as illustrated in the drawings, and for the several purposes set forth.

(Specification, 2s. 9d.; drawing, 1s.)

No. 24958.—22nd September, 1908.—JOHN AVIS PANNETT, of Christchurch, New Zealand, Farmer. Improved means for use in draining the waters of lakes and lagoons into the sea.

Claims.—(1.) Means for the purpose indicated, consisting of the combination with an outflow culvert, of a chamber arranged at the end of the culvert, closed at its outer end, and formed with an opening extending longitudinally along the bottom thereof, and doors hinged above such opening and adapted to cover it, substantially as specified. (2.) Means for the purpose indicated, consisting of, in combination, an outflow culvert, a chamber at the end of such culvert provided with a closed end and with an opening extending longitudinally along the bottom thereof, hinged doors adapted to cover such opening, and lock-gates for dividing the chamber from the culvert, substantially as specified. (3.) The improved means for use in draining the water of lakes and lagoons into the sea, substantially as described and explained, and as illustrated in the drawings.

No. 24959.—23rd September, 1908.—GEORGE HARKER, of 35 Boulevarde, Petersham, near Sydney, New South Wales, Australia, Doctor of Science of the University of London. Improvements in apparatus for fumigating and disinfecting ships, buildings, and sewers.

Extract from Specification.—In carrying out my said invention I use, as a vehicle or medium to carry the fumigant or disinfectant gas or vapour, cooled and washed gaseous products of combustion drawn from the funnel of a boiler-furnace, or the gaseous products of combustion from any closed furnace producing flue-gases containing little free oxygen and much carbon-dioxide. The furnace-gases are treated in an apparatus in which water is showered through them for the purpose of reducing their temperature and washing out soot and solid matters, and thereafter they are charged with the fumigant or disinfectant gas or vapour. They are drawn through a trunk or flue from the scrubber and cooler by means of a centrifugal fan or a pump, or by a steam-blast, and forced thereby through pipes of adequate size into the holds, apartments, sewers, or other chambers in which they are to be applied. The feeder or gas-charging device consists of a closed vessel for containing the fumigant or disinfectant, connected by three valved-pipe connections to the centrifugal pump—one for delivering gas from the pump under pressure to said vessel, a second for conveying liquid from said vessel to be dripped into the gas-current through a sight feed glass, and a third for delivering vaporised fumigant or disinfectant to the pump-intake. At the head it has also a valved filling-funnel, and it is provided with a steam-coil vaporiser, a pressure-gauge, a gauge-glass to exhibit the depth of disinfectant being carried in it from time to time and to show the rate of feed of the same into the furnace-gases, and a thermometer to indicate the temperature. The construction of the cooler and scrubber is more particularly described. The gas-pipes are disposed and valved so that by means of the pump charged gases may be conveyed thereby into ships’ holds or other chambers to fumigate and disinfect the same, and drawn out of said chambers subsequently, and so that atmospheric air may be pumped into the said chambers to restore them to habitable condition and to ventilate them. The apparatus is used to treat apartments to destroy insects, vermin, and disease-germs therein, and may be operated periodically to treat grain or like perishables (not injuriously affected by the gases used) to preserve same in storage or transit from destruction by weevils, fungus, or like agencies.

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

No. 24973.—23rd September, 1908.—WILLIAM MORTON, of Princes Street, Dunedin, New Zealand, Mechanical Engineer. Improved multiple balanced current-wheels.

Claims.—(1.) In current-wheels, an even number of wheels in a line across a current, moving alternately in opposite directions, interlacing each other, and capable of being lifted or lowered out of or into the water, all substantially as described and as explained, and as illustrated in the drawing. (2.) Facing-current wheels of screw-like pattern, having their vanes interlaced, and working in opposite directions (rights and lefts alternately), working on a cross-girder, driving a shaft parallel with said girder, and capable of being partly or fully immersed or lifted out of the water, all substantially as set forth. (3.) In combination, on floating pontoons, an even number of wheels facing the current, travelling in opposite directions, their vanes being interlaced, for the purpose of obtaining power, with gearing to work the main shaft, the immersed machinery being capable of being lifted clear of the water, all substantially as set forth.

No. 24975.—25th September, 1908.—JOHN WILLIAM McCARTY, of Palmerston North, New Zealand, Blacksmith. An improved spanner.

Claims.—A spanner, comprising a disc pivoted upon a pin slidable in a handle, and having circumferential slots adapted to receive nuts of various sizes and to engage a lug upon the handle, substantially as set forth. (2.) The combination and arrangement of parts comprising the improved spanner, substantially as and for the purposes set forth, and illustrated in the drawing.
