No. 24218.—3rd April, 1908.—FREDERICK GARDNER COTTRELL, Ph.D., of 1512 Hawthorne Terrace, Berkely, Alameda County, California, United States of America, Assistant Professor of Physical Chemistry in the University of California. Improvements in the art of separating suspended particles from gaseous bodies.

Claims.—(1.) In the described process, the subjection of the gaseous bodies to the action of a system of electrodes maintained at a high difference of electrical potential and essentially constant polarity by intermittent connection with a source of alternating current at intervals synchronised with the period of said current, and covering the peak of the voltage waves. (2.) In the described process, the transfer of electricity from the metallic circuit to the gas and its suspended particles, by means of an electrode having a pubescent surface. (3.) In the described process, the juxtaposition of electrode surfaces of the type mentioned in claim 2, bearing electrical charges of one sign, with smooth electrode surfaces bearing electrical charges of the opposite sign. (4.) In the described process, the maintenance of high electrical potential difference between the electrodes during the intervals between contacts with the charging source, by the introduction of an electro-receptive device in parallel with the electrodes. (5.) In the described process, the maintenance of insulation between the electrodes and the walls of the precipitation chamber by the introduction of a current of clean gas over the surface of the solid insulation between these.

No. 24220.—6th April, 1908.—ARTHUR ELLIS, of Dunedin, New Zealand, Flock-manufacturer. Improved spring wire mattress.

Claims.—(1.) The general construction and combination of parts composing my “improved spring wire mattress,” substantially as and for the purpose set forth with reference to the drawings. (2.) An improved mattress, consisting of a double carrier-frame, volute springs secured to the said carrier-frame, a double-fabric frame supported by the said springs and carrier-frame, a strand of the fabric surrounding a side rail of each of the fabric frames to form a hinge, substantially as and for the purpose set forth, and as illustrated.

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

No. 24225.—7th April, 1908.—WILLIAM WALLACE PEARCE, of 292 Cashel Street, Christchurch, Canterbury, New Zealand, Gentleman. An improved necktie-holder.

Extract from Specification.—The invention relates to holders used for keeping neckties tidy, and consists of a wire frame with sloping ends, and with a wire coiled around its lower member. One end of this wire projects into the frame, and the other end is coiled around the sloping end of the frame to form a stop. A length of elastic is attached by rings to a sloping end of the frame and to the projecting end of the wire. The upper member of the frame is made to open for the introduction of the neckties, which are placed upon the lower member of the frame and held by the elastic.

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

(Specification, 2s. 6d.; drawing, 1s.)

No. 24226.—7th May, 1908.—WILLIAM WALLACE PEARCE, of 292 Cashel Street, Christchurch, Canterbury, New Zealand, Gentleman. An improved combined writing-case and stationery-cabinet, and fittings therefor.

Extract from Specification.—A cabinet constructed according to my invention has a front hinged to fold down to give access to the interior compartments. A handle attached to the lid of the cabinet is bifurcated at both ends, so that when the cabinet is lifted it will be held level. The lid has a turn-button whereby it is held open at a predetermined angle, and has a hinged leg which maintains the lid horizontally. A slidable partition divides the cabinet into compartments for holding envelopes and writing-paper, and is removable to give access to two boxes, one containing an ink-bottle and the other incidental articles. The front of the cabinet has two pivoted arms, used to support a letter or the like. The lid has a hole which receives a peg projecting from a short wooden support, which is brought into use when the lid is employed as a writing-desk.

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

(Specification, 4s.; drawing, 3s.)

No. 24240.—24th April, 1907.—THOMAS AITKEN, M.I.C.E., of County Buildings, Cupar-Fife, Scotland, Surveyor. Improvements in or relating to apparatus for distributing liquids on roads.

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

Claims.—(1.) In the treatment of roads, forcing a surface-dressing liquid into the crust of the road under pressure. (2.) In a vehicle for forcing surface-dressing into roads, the combination with a liquid-supply tank and a receiver into which air and liquid are pumped under considerable pressure, of a regulating valve between the supply-tank and the pump to control the proportion of air and liquid pumped into the receiver. (3.) The complete apparatus for forcing surface-dressing into roads, substantially as described, or as illustrated in the drawings. (4.) A nozzle such for example as is illustrated in Figs. 3, 4, and 5 of the drawings.

(Specification, 5s. 6d.; drawing, 1s.)

No. 24243.—9th April, 1908.—RUDOLF SPOENDLIN, Dr. Jur., of No. 16, Kreuzbuhlstrasse, Zurich, Switzerland, Engineer. Improvements in pumps and apparatus for obtaining motive power.

Claims.—(1.) A pump consisting of a short vertical pipe free to turn about a vertical axis, and carrying one or more branches which incline upwards and outwards from it, substantially as described. (2.) The combination of a pump or other sucking apparatus and a turbine on its inlet pipe, substantially as described. (3.) The combination of a rotary pump or other sucking apparatus and a turbine or turbines fixed to its outlet or outlets, and rotating with it, substantially as described. (4.) Partly or wholly driving the pumps referred to in claims 2 and 3 by means of the turbines, substantially as described. (5.) The combined apparatus, substantially as described and shown in the drawing.

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

No. 24246.—9th April, 1908.—GEORG JOHAN EUGEN SUNDBERG, of Vesterlanggatan 65, Stockholm, Sweden, Director; and CARL JAKOB JOHAN HAGG, of Husby Hagaryd, Sweden, Dairyist. Improvements in milking-machines.

Claims.—(1.) A milking-machine having compressible teat-cups characterized by a number of cam-discs placed the one above the other and centrally in relation to the said teat-cups on a common shaft, and acting when being rotated directly on the teat-cups or on protection-pieces placed in front thereof, the said cam-discs being so displaced in relation to each other that each teat-cup is at first actuated by the uppermost cam-disc, and then by the next lower one, and so on, substantially as described. (2.) In a milking-apparatus as set forth in claim 1, the arrangement that the cam-discs have such a shape and such a position relative to each other that they release the teat-cups in order, commencing at the top, but in such a manner that one cam-disc does not release a teat-cup until the next lower one has fully engaged the same teat-cup, substantially as described. (3.) In a milking-machine as set forth in claim 1, the arrangement that only the uppermost cam-disc is rigidly connected to the shaft 7, while the other cam-discs are rotatable relative to the shaft within such limits that they can be turned into a position in which they are fully covered by the uppermost cam-disc, the cams of the said discs being of less extension in peripheral direction than the distance between two adjacent teat-cups, substantially as and for the purpose set forth.

(Specification, 4s.; drawing, 1s.)

No. 24256.—10th April, 1908.—CHRISTIAN MEULI, of Eltham, New Zealand, Saddler. An improved fastening for the fronts of animal-covers.

Claims.—(1.) Means for securing the fronts of animal-covers, the same consisting of a length of metal bent to conform approximately to the animal’s breast, and provided with a hook on each end thereof, in combination with loops or rings secured one on each side of the front opening of the cover, and adapted to pass on to the respective hooks, substantially as specified. (2.) Means for securing the fronts of animal-covers constructed substantially as described and explained, and as illustrated in Fig. 2 of the drawings. (3.) Means for securing the fronts of animal-covers constructed substantially as described and explained, and as illustrated in Fig. 3 of the drawings.
