Title: Distillation columns
IPC: B01D1/00
Filed: 1960-08-24
Abstract: <PICT:0933281/III/1> The vapours withdrawn from the vapour-space 3 of a fractionating column are led into a condenser 4, the condensate flows down pipe 6 into vessel 7, from which it is continuously pumped up pipe 10 into a liquid-receiver 11 in the top of the column; and part of the condensate in this receiver flows down capillaries 12 to serve as reflux to the column, the required liquid-level being maintained in receiver 11 by means of overflow-pipe 13 which returns some of the condensate to vessel 7.  The condensate, before it enters receiver 11, is heated by passing it through a coil disposed in the vapour-space 3 of the column.  Any condensate which forms in the vapour-space drains down through pipe 2 into the condenser 4.  The condenser may be connected via cooling-trap 5 to a vacuum-pump (not shown).  Condensate is withdrawn from the system via valve 8.  In a modification, the condenser may be mounted cylindrically around the column.  The separation of heavy water from ordinary water is mentioned.

Oct. 28, 1931, Nos. 29850 and 33602. [Class 82 (ii).] The dirt is discharged from a jig by a rotary valve in fixed relation to and engagement with a rotatable actuating member which is rotated by any suitable source of power, the motion imparted to it being controlled by the movements of a float resting on the shale bed. The actuating member and the driving means may be connected through a clutch which is operated electrically or otherwise by the movements of the float. In the form shown the shale discharge 7 is provided with a rotary valve 8 connected through mitre gears 10 to a vertical rotary actuating shaft 9. The upper end of the shaft 9 is connected through mitre gears 11, a variable gear-box 12 and a magnetic clutch 13 to a driving belt or chain 14. A float 17 resting on the shale bed is supported by a rod 18 working in guides 19 and connected at its upper end by a chain or cord 20 to a counterweight 21. The chain or cord 20 passes through a switchbox 16 and actuates make-and-break devices controlling the magnetic clutch 13. The speed of rotation of the actuating shaft 9 may be varied by changing the gears in the variable gear-box 12 which may be done either by hand or by the float through an auxiliary make-andbreak device in the switch-box 16, by which, for example, if the float rises to an excessive height the speed of rotation of the shaft 9 may be increased. Alternatively a variable-speed electromotor controlled by the movement of the chain 20 through make-and-break devices of a rheostat in the switch-box 16 may be employed to rotate the actuating shaft. Switches may be actuated at various points in the rise and fall of the float so that the speed of the motor is varied gradually and the floatoperated rheostat is preferably used in conjunction with a manually-operated rheostat. In all methods of electrical control the switchbox 16 may contain make-and-break devices of a relay circuit which controls the main circuit. The clutch 13 may be operated manually by the press-button 24 in the event of breakdown of the automatic control.

Abstract: 1325670 Axial-flow fans NORDISK VENTILATOR CO A S 25 June 1971 [10 July 1970] 29998/71 Heading F1C An axial-flow fan has impeller vanes which are adjustable cyclically during an adjusting movement during fan operation. In one embodiment, Fig.1, the vanes 3 have eccentric members 5 which engage a groove 6 in an adjusting disc 7 mounted on a shaft 8 slightly inclined to impeller drive shaft 2. The impeller and disc are rotated with their respective shaft at the same speed. The disc 7 thereby oscillates at a small angle relative to the members 5 but small free-play at groove 6 and material elasticity prevent consequential adjustment of the vanes 3. Impeller vane adjustment is made by axial movement of shaft 8, the inclination of the plate 7 being such that during the axial adjusting movement the vanes are adjusted cyclically so that the pitch of at least one but not all of the vanes is adjusted at a time. The members 5 may instead be connected to the plate 7 by links (15), Fig.4 (not shown), the linkage having the necessary free-play. In another embodiment, Figs.11 and 12, (not shown), the shaft (8) is not rotatable. In Fig.13 (not shown), the plate (7) is mounted on a sleeve located on a fixed shaft (8) for hydraulic adjustment in the axial direction. In other embodiments the vane adjustment is effected by angular adjustment of an inclined plate (7) receiving the eccentric members (5) in axial slots (16), Figs. 5 and 6 (not shown), or connected thereto through links (17), Figs.7 and 8 (not shown). Fig.15 (not shown) displays two impellers mounted on opposite ends of a common hollow driving shaft (35) and each having vanes adjustable by a respective plate carried by an inclined shaft, the two inclined shafts being connected by a universal coupling. In another embodiment, Figs.9 and 10 (not shown), the axis of the adjusting shaft (8) is parallel but eccentric to the impeller shaft axis, and the plate (7) lies perpendicular to shaft (8) and has gear teeth (19) at its periphery in engagement with pinions (18) carried by the impeller vanes. The angle of the inclined adjusting shaft or the spacing of the eccentric adjusting shaft may be regulated; e.g., the eccentricity may be regulated by rotating one eccentric sleeve relatively to another eccentric sleeve.
