Title: Improvements relating to vehicle brakes
IPC: F16D55/46
Filed: 1939-06-24
Abstract: 520,279. Disc brakes. PRATT, J. H:, MANLEY, G. E., and GIRLING, A. H. G. June 24, 1939, No. 20224/38. [Class 103 (i)] In disc brakes of the kind in which a non- rotating member is moved to clamp a rotating friction disc and in which means are interposed between the clamping member and a fixed part whereby the tendency of the clamping member to rotate consequent upon its initial engagement with the disc effects an increase in the clamping action and of the braking effort, the interposed means and the means for initially engaging the clamping member with the disc act on different parts of the disc thereby providing for am oblique approach of the clamping member towards the disc. In the form shown, a wheel 6 has bolted to its inner side a carrier plate 7 having a plurality of slots 7c in which are engaged corresponding projections 8 of a metallic disc 9 which carries brake blocks 10 of friction material. The disc 9 is formed of upper and lower separable halves which can be removed after removal of the plate 7. The disc 9 is axially movable relative to the wheel 6. Two clamping members 11 and 12, of which the inner, 12, is axially movable, are adapted to exert a braking effect upon actuation by a lever 21 which is fulcrummed upon knife-edges 22 on the fixed hub casing 14 and acts through ball-ended struts 25 on the member 12. Between the fixed casing 14 and the member 12 are balls 18 in conical pits which give a self-energizing action on application of the brake. The balls may be replaced by rollers, or ball- or knife-ended struts may be used. Springs 19 are arranged to return the brake to the off position. A pair of hydraulic cylinders located adjacent the struts 25 may be used to apply the brake in addition to or instead of the lever 21. The clamping member 11 is held in position by means of a ring 16 screwed on to the hub 14, which may be adjusted by means of a tool 15 provided with a pinion 15a adapted to engage with teeth on the periphery of the ring. The balls 18 or equivalent are located only at the upper part of the members 12, 14 and the lever 21 or hydraulic cylinders act on the lower part of the member 12 so that the member 12 approaches the disc 9 obliquely.

Title: Improvements in or relating to the recovery of tin from tin scrap
IPC: C22B25/06
Filed: 1935-07-19
Abstract: In the recovery of tin from tin scrap, the tin is dissolved in an acid solvent such as concentrated hydrochloric acid or dilute hydrochloric acid and chlorine, the stannous chloride so formed oxidized to stannic chloride as by means of chlorine, excess acid neutralized for instance with caustic soda or lime, and the tin then separated by hydrolysis, as by dilution and boiling of the solution. If lead and copper are present, the solution, before hydrolysis, is boiled with nitric acid or ammonium nitrate to convert them into nitrates which remain in solution during hydrolysis.  The precipitated stannic acid may be reduced to metal, as by furnacing with anthracite.  Before detinning, the scrap may be cleaned by treatment with a caustic soda solution.
