Title: Improvements in variable speed gearing
IPC: F16H37/08
Filed: 1924-01-14
Abstract: 218,212. Fielden, F., and Fielden, A. Jan. 14, 1924. Variable-speed gearing comprises an epicyclic train with stepped planet gears B<1> controlled by disc-and roller gearing K, E, which is replaced by a clutch G, J on the highest speed. The carrier B of the planet gears is last on the driving- shaft A. The driven shaft C is fast to a sun gear C<1> which is larger than the controlled sun gear D. The roller E slides on splines on a loose sleeve D<1> to which the gear D is secured. Clutch members J, L are splined upon the shaft A. The latter normally entrains a chain M which drives a shaft K<2>, which through a worm drives the spring- pressed disc K. A cam 4 increases the pressure of the disc K on the roller E. A cam 6 withdraws the disc from the roller when the clutch drive comes in. This is effected when the disc E is moved so far to the right that a cone surface G engages the clutch member J. Further movement carries the member J to the right until it strikes a sleeve L<1> and so disconnects the clutch L, and with it the disc-and-roller gearing. The operation of the disc E and cam 6 are co-ordinated. Reversed driving is possible.

Patent GB-998262-A (GB)
Title: Catalytic cracking
IPC: B01J29/06
Filed: 1962-01-12
Abstract: A method for the catalytic cracking of hydrocarbons employs as a catalyst composition a crystalline aluminosilicate with a total hydrogen in content of at least 0.5 equivalents per grain atom of aluminium and a total alkali metal content of less than 0.25 equivalents per grain atom of aluminium, such aluminosilicate being intimately mixed with a matrix.  The crystalline aluminosilicates used in this invention are obtained by heating any natural or synthetic crystalline aluminosilicate either before or after its incorporation in the matrix with a fluid medium, preferably water, containing hydrogen ions or ions capable of conversion to hydrogen ions, e.g. ammonium ions until the desired concentration is reached. Long lists of suitable zeolites and clays is supplied.  The matrix may be an inert or catalytically active material, and is preferably a siliceous gel matrix.  The matrix and the aluminosilicate may be combined in a variety of ways.  The siliceous gel matrix may also consist of a plural gel comprising a predominant amount of silica with one or more metals or oxides thereof selected from Groups II, III, IV, V, VI, VII and VIII of the Periodic Table.  The cracking activity of the catalyst is illustrated by its ability to catalyze the conversion of a Mid-Continent Gas Oil having a boiling range of 450-950 DEG  F. to gasoline having an end point of 410 DEG  F. Vapours of the gas oil are passed through the catalyst at temperatures of 875 DEG  or 900 DEG  F. substantially at atmospheric pressure and a feed rate of 1.3 to 16.0 volumes of liquid oil per volume of catalyst per hour for ten minutes.
