Abstract: 720,769. Sand blasting shoes &c. SIMONSEN, K. J. March 2, 1953 [March 5, 1952], No. 5811/53. Class 60. A method of cleaning and decolorizing shoes and other leather articles, such as coats, handbags and the like, for re-dyeing if desired, comprises subjecting the leather surface to the action of a current of air the pressure of which is between 1.25 and 11 kgs/cm<SP>2</SP> and which contains roughgrained sand, the size of the grains being between 0.05 and 1.5 mm. The size of the nozzle opening is between 1 and 6 mm. and preferably between 2 and 4 mm. If the leather article is very old and dry it may be softened before blasting or dyeing by an agent such as paraffin oil, castor oil or some fat. Portions of the article can be protected from blasting by masks e.g. of paper coated with rubber or by coating with a mineral fat To reduce the generation of friction heat the current of air may contain in addition to the sand one or more mineral acid salts of alkaline metals and/or alkaline earth metals, for instance sodium and/or potassium salts, such as the chlorides, the sulphates, the carbonates, the phosphates and the corresponding ammonium salts, in a quantity varying from 1 to 25 and preferably from 5 to 15 per cent of the weight of the sand. After blasting to clean the leather surface, a further blasting using a smaller quantity of-sand and higher pressure is performed to obtain a fluffy surface, aniline, latex, methyl alcohol and castor oil are then applied by a spray gun; the leather is smoothed by a rotating brush and collodion dye is sprayed on.

Abstract: 578,054. Plucking feathers or hair. DORIN, A. March 30, 1944, No. 5883. [Class 28 (ii)] In plucking birds or removing hair from animals by gripping and withdrawing the feathers &c. by pairs of rotated discs, the discs 14 recede from, and approach each other coaxially and repeatedly in each revolution to effect grip and release. The gripping discs are dished and the peripheries are notched as at 41 or of sinuous periphery to form a desired number of plucking points 42. The discs 41 are mounted on the splines of a shaft 15 driven by a belt 23 from another shaft 16 driven by an electric motor. Each pair of plates is held apart by a pair of dished spring discs 33, Fig. 8, while the pairs of discs are held apart by other spacing discs 34 of less resiliency, so that when axial pressure is applied to the discs the gripping faces of the pairs come together first. The axial pressure is applied by a pair of lever arms 31. each with cam ribs so that when opposed rocking motion is applied to each of the lever arms 31, the cam ribs ride over each other to effect axial pressure on the plucking plates. The lever arm. 31 are rocked through links 30 pivoted to a common cross-bar 29 attached to a guide rod 26, the roller end of which is engaged by the risers of a cam 21 on the shaft 16. The cam 21 is designed with the appropriate number of risers proportional to a number of plucking points 42 on the periphery of the plucking discs. The machine is enclosed in a casing 10 provided with a fan rotor 17 sucking air through the opening 12 and delivering feathers through a double outlet 19 provided with a flap valve to direct the feathers through an opening into a bag so that one bag can be removed while the other is being filled. The casing is also provided with a rest 13 on which poultry can be placed during operation.

Abstract: 365,845. Rectifying alternating current ; charging batteries. DEAN, F. L. W., 21, Bartlett's Buildings, Holborn Circus, London. Feb. 25, 1931, No. 5962. [Classes 38 (ii) and 38 (iv).] In an arrangement for supplying wireless sets &c. from mains in which a column of static contact rectifiers of the metallic oxide type is used for high tension supply, provision is made whereby one or a small group of the rectifier elements may be used for supplying low tension current for battery charging for example. Fig. 2 shows one arrangement in which switching provision is made whereby with one setting the transformer secondary 25 supplies high tension current through the whole column of rectifying elements 21 whilst a battery 33 supplies low tension current. In the alternative setting, the high tension supply is interrupted, and the battery is charged from the transformer secondary 26 through the end pair of rectifying elements 22, 23. In a modification (Fig. 3 not shown), two separate transformers are used and the two rectifying elements at opposite ends of the column are brought into parallel relation when battery charging connections are established. In a further arrangement, Fig. 5, a pair of condensers 83, 84 are used in conjunction with a midpoint tapping on the rectifier column to provide a voltage doubling circuit fed by the whole of the transformer secondary 86, 87 when the high tension supply connections are established by raising switches 92, 93, 94 to the upper positions. With the switches in the lower positions, the part 87 of the transformer secondary feeds the battery charging circuit through the end rectifying elements of the upper half of the column. In a further arrangement, Fig. 6 (not shown), a separate transformer is provided for high tension supply, and the connections are modified to bring the rectifying elements at opposite ends of the column into use for battery-charging. In another arrangement, Fig. 4 (not shown) in which the voltage doubling circuit is employed, the arrangement is such that either of the two rectifying elements at the centre of the column may be used at will for low tension supply.
