process of manufacturing a detergent powder consisting of mixing oleic acid and oatmeal with caustic alkali of a density to cause the evolution of ammonia, and then suitably destroying the causticity of the said mixture, converting the fluid water into water of crystallization, and drying the mixture. (6.) The modified process of manufacturing a detergent powder consisting of mixing oatmeal or other suitable cereal with oleine or oil, and adding thereto a charge of caustic alkali in solution, after which a charge of sodium-bicarbonate is added, and then run through a sieve for granulation, the product being then shortly ready for grinding for use as a detergent powder, as described.

No. 15046.—27th June, 1902.—CLAUDE ROBINSON, of Queen Street, Auckland, New Zealand, but temporarily of Adelaide, South Australia, Watchmaker. Improvements in the method of and means for the destruction of vermin.

Claims.—(1.) The described method of and means for destroying vermin which consists of a fence placed round the burrows or cover of the vermin, such fence being characterized by having its lower portion so open as to form no obstruction to the passage of the animals, and being provided with a sliding or swinging obstructive lower half arranged in such a manner as to be capable of instantaneously, or practically instantaneously, forming a barrier whereby the animals which have passed from their cover to beyond its confines are prevented from returning to their cover, substantially as described and illustrated according to the method indicated. (2.) In an improved method of and means for destroying vermin, a series of panels provided with sliding links and mounted upon tee-iron standards so as to form a continuous vertically sliding barrier, substantially as described and illustrated in Figs. 1, 2, and 8 of the drawings. (3.) In an improved method of and means for destroying vermin, the combination of a series of panels provided with link-plates and sliding links and a series of tee-iron standards, said standards containing pin-holes and being fitted with supporting pins and operating cord or chain, arranged substantially as described and illustrated, as and for the purposes set forth as a combination of parts. (4.) In an improved method of and means for destroying vermin, the application and use of an auxiliary tee-iron standard in combination with existing posts, and provided with parts mentioned in claim 3, as and for the purposes set forth, and as described with reference to Fig. 7 of the drawings. (5.) In an improved method of and means for destroying vermin, a length of swinging netting or panels, supported at its upper edge to a fence-wire or its equivalent, and provided with runners such as K, together with a series of corresponding guides such as L and the sliding locking-rings, M, arranged substantially as described, and illustrated with reference to Figs. 3 and 6 of the drawings. (6.) In an improved method of and means for destroying vermin and in combination with the parts set forth and claimed in claim 5, a prop or standard such as N, provided at its upper end with a fork and pin such as N¹ and N², and auxiliary catch or projection N³, and a loop or eyelet O for the reception of a cord or chain, substantially as described, and as illustrated in Fig. 6 of the drawings. (7.) In an improved method of and means for destroying vermin, a fence placed round the burrows or cover of the vermin, such fence being characterized by having its bottom portion so open as to form no obstruction to the vermin, but being also provided with a length of wire netting, said netting being fitted with stretchers and stiffeners, and being mounted upon auxiliary radial posts, whereby it is capable of being raised or lowered by vertical movement, substantially as described, and illustrated with regard to Fig. 4 of the drawings. (8.) The specified means for destroying vermin, operated and arranged substantially as described and illustrated, as and for the purposes set forth as a combination of parts.

No. 15047.—27th June, 1902.—WALTER C. RUNGE, of 49, Queen Victoria Street, London, England. Improvements in or relating to the sound-trumpets of graphophones or the like.

Claims.—(1.) In a graphophone or the like, a sound-trumpet having two or more longitudinal stiffeners serving to improve its sound-producing qualities. (2.) In a graphophone or the like, a sound-trumpet having a clip G¹ joining the edges of the sheet of material of which the trumpet is made and serving as a stiffener, and another stiffener in the form of a longitudinal bend or crease G⁵ in the opposite side of the trumpet. (3.) In a graphophone or the like, the combination with a pivoted sound trumpet of a spring support such as J⁴ to cause the stylus to bear with an elastic and yielding pressure in the grooves of the record. (4.) In a graphophone or the like, the combination with a sound-trumpet of a lifting-device such as K K¹, substantially as and for the purpose described. (5.) In a graphophone or the like, the combination with a sound-trumpet having two or more longitudinal stiffeners of a lifting-device K K¹ and a spring support J⁴, substantially as described, and illustrated in the drawings.

No. 15048.—27th June, 1902.—WILLIAM CROCKER QUINBY, of 2929, Lincoln Avenue, Alameda, California, United States of America, Chemist; and JOHN JEFFERSON MOORE, of 418, California Street, San Francisco, California aforesaid, Merchant. Improvements in the manufacture of explosive compounds.

Claims.—(1.) An explosive compound composed of granules of oxygen-bearing salts combined with maltha. (2.) An explosive compound composed of oxygen-bearing salts in the form of granules covered by a coating of maltha. (3.) That improvement in the manufacture of explosive compounds containing oxygen-bearing agents in the form of granules consisting in covering the granules with a coating of maltha.
(Specification, 5s.)

No. 15063.—30th June, 1902.—ARCHIBALD MCFARLANE, of Upper Hutt, New Zealand, Timber Merchant. Improvements in the construction of butter and other boxes.

No. 15068.—2nd July, 1902.—FREDERICK MONDELET GAUDET, of Quebec, Canada, a Major in His Majesty’s Regiment of Royal Canadian Artillery and Superintendent of the Dominion Arsenal, at present residing at 5, Gloucester Walk, West Kensington, London, England. Improvements in targets for miniature ranges.

Claims.—(1.) In a target for miniature ranges, the combination with an aiming-target of a scoring-target of such size that the skill required to place a shot in any of its divisions with miniature ammunition is equal to the skill required to place a shot in the corresponding division of the full-sized target with full sized ammunition, the vertical distance between the centres of the aiming-target and of the scoring-target being equal to the vertical distance between the trajectory and the line of sight at their intersection with the plane of the miniature target, as and for the purpose specified.
