Title: Method and apparatus for removing tobacco from a supply
Inventor: WOCHNOWSKI WALDEMAR
IPC: A24C5/39
Filed: 1969-08-06
Abstract: 1285771 Automatic control of tobacco flow HAUNI-WERKE KORBER & CO K G 6 Aug 1969 [23 Aug 1968 21 March 1969] 39350/69 Heading G3R Tobacco removed from a bulk supply by a picker conveyor is supplied to a stationary container from which it is withdrawn at a controlled or predetermined rate, the picker conveyor being controlled by a signal dependent on the quantity of tobacco in the container so that the flow therefrom is substantially uniform. In one arrangement shown, bales 302 of compressed tobacco are swung on to a conveyor 308 by a transfer conveyor 332 and tobacco is removed therefrom by a spiked conveyor 307 and deposited in relatively loose form into a container 317. Tobacco is continuously removed from container 317 by a further spiked conveyor 324 and a photo-cell 319 is arranged to operate a delayed relay 323 and thereby switch on or off an electric motor 314 driving conveyors 307, 308 according to whether the tobacco in container 317 is below or above a predetermined level. The tobacco from conveyor 324 is supplied to another conveyor 341 pivotted at 361 and supported by a spring 363 so that a potentiometer 364 is operated according to the weight of tobacco. The output of potentiometer 364 is multiplied by the output of a tachometer generator 366 associated with a motor 325 driving conveyors 324, 341 so that a signal is produced at 365 corresponding to the mass rate of flow. This signal is compared at 370 with a signal from a potentiometer 372 corresponding to the desired rate of flow so that any error is automatically corrected by control of the speed of motor 325 through a controller 369. Modifications involving the removal of loose tobacco from a store in a container, e.g. to form a tobacco rod, by a conveyor driven by a two-speed motor automatically controlled to maintain the level in another container between predetermined limits are described. Automatic speed control of intermediate conveyors through magnetic amplifiers or thyristors to maintain a constant flow which may be varied in dependence on other factors is described.

Oil in the compressed air discharged through outlet 30 is separated from the air by filter means (not shown) and returned to gallery 62. Air is inducted through an inlet 28, and a further set of bearing assemblies for the inlet ends of the rotors are lodged in another end wall of the housing (Fig. 1, not shown).

Abstract: 1464297 Fuel elements UNITED KING- DOM ATOMIC ENERGY AUTHORITY 14 Aug 1975 [17 Sept 1974] 40472/74 Heading G6C A nuclear fuel element comprises a cluster of fuel rods supported axes parallel in spaced apart relationship by transverse grids so as to define interspaces for the axial flow of main coolant and having at least one of the interspaces occupied by an axially extending auxiliary coolant conduit with lateral holes through which auxiliary coolant is sprayed into the cluster, deflection means extending from a transverse grid into a position in front of the holes for deflecting auxiliary coolant spray on to parts of the fuel rods otherwise inaccessible to auxiliary coolant. In the embodiment illustrated, a transverse grid 3 comprises an outer band 4 joined at 60 degree intervals to webs 5 to form sectors each containing six fuel rod positioning ferrules 6, correct positioning of which is assisted by C- shaped spacers 7. An auxiliary coolant conduit 8 extends through and is fixed to a central ferrule 9 to which the inner ends of the webs 5 are secured. The conduit 8 is closed at one end and has a number of holes (10) (Fig. 2, not shown), in its wall so that when it is connected at its other end to a source of auxiliary coolant, the latter will emerge as a plurality of sprays directed transversely into the cluster. This spray cooling is useful as an alternative or supplementary cooling to the axial flow of main coolant. A number of T-shaped plates 11 are attached by their arm-pieces 11a to adjacent ferrules 6 by welds 12 and have their stems 11b in the line of sight from one or more holes (10) in the conduit 8. The edges 11c of the stem 11b are sharply defined, making an angle of 60 degrees with the face of the plate 11. The plates 11 serve to deflect the sprays from the holes (10) on to parts of the surfaces of fuel rods 2 which, being partially masked by other rods, may not otherwise be properly wetted by auxiliary coolant.
