Filed: 1925-12-15
Abstract: 245,434. Scherbaum, J. B. C. Dec. 30, 1924, [Convention date]. Disc mills. - In a pulverizing-mill with two interengaging discs having meshing tapered teeth that preferably increase in number and decrease in height towards the peripheries of the discs, the angles formed by the radial flanks of a tooth with the surfaces of the disc, and the length of the tooth, are such that a plane extending through the end of the edge of a tooth flank and at rightangles to this flank intersects the bottom edge of the opposite flank of the tooth. As shown, the stationary disc 3 and rotary disc 5 are provided with a series of preliminary breaking teeth 7, which decrease in height and increase in number outwards, and several rows of fine-grinding teeth 8 of equal height, with two rings of intermediate rough-grinding teeth 12. The radial flanks 9 of a tooth are so inclined to the surface of the disc, and the length L of a tooth is such, that a plane extending through the edge a of a flank and at right-angles to this flank intersects the bottom edge b of the opposite flank. The inner peripheral flank 10 is inclined at a smaller angle to the surface of the disc than the outer peripheral flank 11. The gaps between the teeth 8 of the fixed disc 3 lie on straight radial lines, while those of the teeth 8 of the rotary disc 5 lie on curved lines. The teeth 7 are, and the teeth 12 may be, offset in relation to one another so that the material being ground travels in a zig-zag path from the centre to the periphery of the discs.

Filed: 1955-11-07
Abstract: 783,938. Regulating. DAIMLER-BENZ AKT.-GES. Nov. 7, 1955 [Dec. 6, 1954], No. 31775/55. Class 7(6) [Also in Group XXXI] In a motor vehicle engine exhaust control having a hand lever 4 controlling exhaust braking, interconnected with the vehicle accelerator and clutch pedal linkages whereby the hand lever shuts off the engine fuel supply on exhaust braking and depression of the accelerator or clutch pedal first cancels the exhaust braking, an adjustable stop 11 arrests the hand lever 4 in its "off" position, adjustment of the stop being effective to alter the fuel supply for idling when exhaust braking is cancelled. As shown the hand lever 4 is disposed beneath the steering wheel 3 and connected by a transmission including a stirrup 12 to a throttle valve 5 in the exhaust pipe 6, the arrangement being such that movement of the lever 4 to its braking position can be cancelled by initial depression of either the accelerator pedal G or clutch pedal K. The hand lever 4 is carried by a rod 2 supported in a bracket 7 carried by a column 1 surrounding the steering shaft 8, the bracket carrying a lug 9 receiving a screw forming the stop 11 having a milled head 10. The lever 4 engages the stop 11 when the exhaust brake is inoperative, and, as the stirrup 12 limits the movement of the accelerator linkage when the pedal G is released, movement of the screw in the bracket adjusts the engine idling position.

Title: Improvements in or relating to the hydrofining of hydrocarbons
Inventor: POTTER EDWARD BARRIE VERNON
IPC: C10G65/16
Filed: 1953-11-19
Abstract: A process for hydrofining simultaneously, in a series of reaction zones, more than one hydrocarbon fraction, comprises passing the first fraction and a hydrogen-containing gas into a first hydrofining zone and passing the hydrogencontaining gas, separated from the condensed hydrofined hydrocarbons to the next reaction zone wherein the succeeding hydrocarbon fraction is hydrofined, the gas obtained being passed in succession through all the zones in series and the gas from the last reaction zone being recycled to the first reaction zone.  Before recycling to the first reaction zone the hydrogen-containing gas may be freed from hydrogen sulphide by washing with caustic alkali or by absorption with diethanolamine. The process may be applied to the desulphurization of petroleum fractions e.g. gasolines, white spirit and gas oils and the hydrogenation of cracked petroleum fractions such as heating oils and of petroleum lubricating oils and petroleum waxes.  The hydrogenation may be carried out wholly or partly in the vapour phase and in the presence of a catalyst such as cobalt molybdate, or alumina or tungsten or nickel sulphides; fixed bed or fluidized processes may be used.  Suitable hydrofining temperatures are 400-800 DEG F. and suitable pressures are 50-500 p.s.i.g.
