Abstract: 1,075,707. Grinding crank-shafts. RHEINSTAKE HEUSCHEL A.G. Oct. 16, 1964, No. 42317/64. Heading B3D. A crank-shaft grinding machine comprises a grinding wheel 3 mounted in bearings which are carried by an arm 5 mounted on a torsionally rigid pivotable axle 12 supported for oscillating movement in bearings in the machine bed above or below the grinding wheel, the axle also serving as a guide way for axial movement of the grinding wheel. The crankshaft is supported by its main bearings in steady rests 2 and is joined by a connection 18 to a headstock 8 having a motor 23 for rotating the crank-shaft by means of a chain drive. The crank-shaft may also be driven by a motor 17 in a tailstock, the drive which may be mechanical or hydraulic, applying an adjustable torque to the crank-shaft to control the twisting of the crank-shaft. A pin 7 which is adjustable by a device 20 to be coaxial with a crank-pin 6 of the crank-shaft to be ground is mounted adjacent the headstock 8 and connected by a rod 10 to an arm parallel to the arm 5 which at one end carries the bearings for the grinding wheel and at the other end is mounted on the axle 12. During rotation of the crank-shaft and pin 7, the rod causes the arm 5 to oscillate and the grinding wheel to move to-and-fro as it grinds the crank-pin. A device 15 is carried by the rod 10 to effect feeding of the grinding wheel by varying the distance between the axes of the pin 7 and grinding wheel. Errors in the feed caused by the circular movement of the grinding wheel may be corrected by a control device 16 which varies the speed of the driving motor 23. The eccentric pin 7 is angularly indexable by a device 19 to be aligned with successive crank-pins, the arm 5 being movable along the axle 12 to align the grinding wheel with the crank-pins. The pin 7 may be radially adjusted to a position in which it is not eccentric and is coaxial with the main bearings so that the latter may be ground. A trueing device 21 and a measuring device 22 may be mounted on the arm 5.

A seed sower comprises a plurality of seed cups 4 and feed tubes 5 each provided with flaps 13 that are pivoted by cam wheels mounted on a shaft 11 to deliver seed from a hopper 3, the shaft 11 being driven at a variable speed by a device arranged in a housing 15 and driven by a landwheel 1 the device comprising two cams 22 which are driven through gearing 18, 19 from the landwheel 1 and which co-operate with rollers 26 mounted on triangular plates 24 which are pivoted on a shaft 25. Each plate engages a roller 32 in a slot 31, the roller being mounted on the end of a lever 35 and also engaging in the slot 33 of a lever 28 which drives the shaft 11 when the lever is moved in the direction C only, through gearing and a clutch 40a. The clutch comprises a pawl wheel 29 fixed to the lever 28 and provided with resilient strips 39 which cooperate in one direction only with the inner side of a jacket 40 surrounding each pawl wheel 29 and formed on the said inner side with friction material, the outer side being provided with toothing 41. The driving mechanism is such that a continuous rotation of the shaft 11 is ensured. The levers 35 carrying the rollers 32 are pivoted on a shaft 36 mounted on a lever 37 the position of which can be adjusted from outside the casing 15 to adjust the stroke of the lever 28 and thus adjust the speed of revolution of the shaft 11.

Abstract: 1,199,572. Driving arrangements; regenerative braking. RICHFIELD INDUSTRIAL EQUIPMENT Ltd. 21 July, 1967 [28 Sept., 1966], No. 43360/66. Heading B7H. [Also in Division F2] Fork-lift trucks, industrial tractors, cranes, urban delivery vehicles and golf buggies are driven by an hydraulic power system comprising a flywheel 13 operating in an evacuated casing 4, a pump 7 operating in an oil-filled chamber 2 to initially energize the flywheel and then subsequently being operated by the flywheel to supply oil under pressure to an hydraulic motor 29 fixed to a sump 30 of a gear-case which houses gears 31, 32 and a differential 33 from which half-shafts of the vehicles are powered. An external pump (not shown), driven by an electric motor or diesel engine, supplies high-pressure oil to the pump 7 which, acting as a motor, drives a shaft 8 and a drum 9, and through a belt 11, the cup bearing 12, the flywheel 13 and shaft 17. When the pump is brought up to its maximum governable speed, the stroke of the pump is reduced to zero and the pump is disconnected from the external pressure source. To put the vehicle in motion, the function of the pump 7 is changed by its control lever 43 to cause it to act as a pump driven by the flywheel through the belt 11 and toothed drum 9. The output of the pump 7 is led to the hydraulic motor 29 from whence it is returned to the inlet of the pump 7. When the vehicle is on overrun, e.g., on descending a hill, the motor 29 is caused to act as a pump, and the pump 7 is adjusted to act as a motor, so that this energy is recovered and transmitted back to the flywheel.

Title: Process for the production of uranium metal
IPC: C22B60/02
Filed: 1962-11-20
Abstract: Uranium of nuclear purity is produced from a double fluoride of uranium and alkali metal, NaUF5 which is blended with an excess of Mg powder, formed into cylindrical pellets which are then submitted to thermal reduction in an induction coil housed in a dielectric container which is not gas-tight charged with a refractory powder e.g. ignited dolomite, which confines the Mg vapour.  Electric power at the rate of at least 2 kW. per kilo. of uranium and of frequency 2000-4000 c.p.s. is applied, and current is supplied before, during, and for a short period after the reaction.  During the reaction, which takes about 15 minutes, the container is vibrated.  Uranium ingots of equal diameter/height ratio may be made from pellets formed of two cylinders joined end-to-end with an intervening frusto-conical section. The process may be applied to enriched uranium containing 233 and 235.  The double fluoride is made by reducing uranyl nitrate containing a little HNO3 with hydrogen and a catalyst to form the tetranitrate which is then treated with HF and an alkali metal salt. The precipitated and washed double fluoride is then dried to a moisture content not exceeding 0.1%.
