Title: Improvements in variable speed transmission gear
IPC: F16H3/42
Filed: 1937-07-12
Abstract: 480,421. Variable - speed gearing; toothed wheels. SANTON, E. July 12, 1937, No. 19252. [Classes 80 (i) and 80 (ii)] Variable speeds are transmitted between driving and driven toothed cones 2, 3 by an axially displaceable idler 8, having one or more rows of teeth 9 which can yield radially against springs 11 and centrifugal force, so as to mesh correctly with the cones in any position. Adjacent rows of teeth 9 may be of the same pitch and angularly staggered, or of different pitch, and are carried in discs separated by partitions 16, and either independent of each other, or clamped together by bolts 17, which may also serve to limit outward movement of the teeth. The teeth of the cones and idler may be helical, and the cones carry additional half-length teeth 12, with chamfered ends 13. To prevent jamming, fixed side-plates 34 press the teeth 9 inwardly just before meshing takes place. In order to provide for disconnection of the drive, thus allowing the gear to be used in a motor-vehicle without a mainclutch, the teeth 9 in the engaging zone of either or both cones, can be retracted inwards by depressing a cam-plate 38, Fig. 6, which turns one or two levers 36, contacting pins 39, projecting axially from the gear-teeth 9 through radial slots 40 in the side-walls of the idler 8. The levers 36 have a pin-and-slot mounting 42 on the idler and slide along a fixed pivotshaft 37. The cam-plate 38 may be operated by the vehicle brake-pedal 49, so as to disconnect the gear when the brakes are applied, or it may be manually operated, directly by a pedal 46, or through an electromagnet. A catch is provided for retaining the cam-plate in the operative position. The idler 8 slides on or with a non-rotatable shaft 7, and may be operated by a fork on the end of a screwthreaded parallel shaft, turned by a nut formed as a worm-wheel, engaging a worm on the shaft of a reversible electric motor. Alternatively the idler shaft 7 itself may be screw-threaded and carry an internally threaded toothed bevel-wheel, engaging a bevel-wheel to which is secured a friction bevel-wheel adapted to be engaged alternately by a pair of axially shiftable friction discs splined on the shaft of one of the main cones 2, 3.

Filed: 1921-07-18
Abstract: 187,329. Wade, H., (Continenta-licht-und Apparatebau Ges.). July 18, 1921. Liquid raised up to solid.-In a high pressure acetylene generator having separate gas-storage and generating chambers 1, 4, Fig. 1, a hood is fitted over the gas-delivery pipe 16 and is carried by a float-device arranged in such a manner that increase in pressure in the storage chamber causes the hood to sink; as a result the pressure difference between the two chambers is increased, the water is driven away from the carbide through the communicating pipe 12, and generation of gas is thereby automatically controlled. Two constuctions of the float device are described. In the first construction a cylindrical hood 17, fitted over the gas-delivery pipe, is formed integral with an outer concentric and cylindrical float 18, Figs. 1 and 2, closed at the upper part and of enlarged diameter at the lower part; small openings 20, 22 are provided in the hood and enlarged lower part of float, to ensuie that at all times the latter is filled' with gas; the fioat device 17, 18 moves freely within a cylinder 23 which surmounts an annular float 24; at the upper part the cylinder 23 is provided with a small lateral opening 25; and to the bottom of the cylinder are secured stops 26 that limit the dcwnward movement of the float 17, 18, while a stop 27 carried by the casing limits its upward movement. In the second construction, the hood 34, Figs. 5 and 6, is carried by a closed chamber of disc shape and constituted by two parallel diaphragms 30, 31 welded together, and the construction is such that an increase in pressure forces inwardly the diaphragms and causes the float to sink; a valved connection 33 is provided for adjusting the pressure inside the chamber of the float. The water pipe 12 which connects the generating and gas-storage chamber is . provided with a cock 13, Fig. 1, the actuating-means 15 of which is so arranged that the cock must be in its closed position before the cover 6 of the generating chamber can be removed.

Title: Improvements in or relating to electroplating
IPC: C01G19/02
Filed: 1965-05-07
Abstract: In a tin-plating process comprising electrodepositing tin from an alkali metal stannate bath and thereby depleting the tin content thereof, the tin content is replenished by adding an alkaline tin oxide sol (e.g. at a rate of 1.107 gms. per ampere-hr. of plating) prepared by reacting at <75 DEG C., an aqueous akali metal stannate solution with acid to a final pH of <6, thereby precipitating hydrous stannic oxide, which is separated and washed to remove water-soluble ions and is then peptized with potassium hydroxide or stannate, maintaining the molar ratio of K/Sn in the final solution at 0.1-1.5 and the hydrous stannic oxide below 75 DEG C. prior to peptizing.ALSO:An alkaline tin oxide sol is prepared by reacting at < 75 DEG  C., e.g. 35-70 DEG  C., an aqueous alkali metal stannate solution, e.g. of 10-500 g/l., with acid, e.g. acetic, hydrochloric, nitric or dilute sulphuric acid or sodium bicarbonate to a final pH of < 6, e.g. 2.5-6, precipitating hydrous stannic oxide, which is separated and washed to remove water-soluble ions, the tin content of the stannic oxide may be adjusted by filtering to 28-40% by wt., adding KOH or potassium stannate to peptize the stannic oxide, maintaining the molar ratio K/Sn at 0.1-1.5, and the temperature of the stannic oxide below 75 DEG  C., e.g. 35-70 DEG  C. before peptizing.  The sol is characterized by its complete convertibility to stannate by solutions of 5-100 g/l. KOH at 50-100 DEG  C.  In a tin-plating process of electro-depositing tin from an alkali metal stannate bath containing an insoluble anode and a cathode, thereby depleting the tin content of the bath this tin content may be replenished by addition of the sol.  If the stannate contains organic impurities, it may be preferred to use NaHCO3 as the acid for partial neutralization to pH 8, when the hydrous oxide may be readily washed free of impurity, reslurried and treated with acid as above.
