Title: Centrifugal separator
IPC: B04B11/06
Filed: 1964-03-03
Abstract: 989,843. Centrifugal separators. SEPARATOR A.B. March 3, 1964 [May 8, 1963], No. 8897/64. Heading B2P. In a centrifuge provided with a distributer disc 5 in the separation chamber and having an inlet 4 for contaminated liquid which opens, e.g. through one or more channels 9 in a discshaped unit 3, into the space on one side of the disc and communicates with the space on the other side, e.g. through holes 6 in the disc 5, a channel 13, 14 in the central part of the disc forms an additional communication between the spaces on both sides of the disc and extends radially inwardly from an opening on that side of the disc remote from the inlet 4, the inlet opening being positioned further from the axis of rotation of the separator than the channel opening, and gas bubbles contained in the contaminated liquid collecting, during separation, in part of the space in which the inlet 4 opens so as to provide a gas seal to prevent the passage of contaminated liquid from the inlet 4 through the channel 13, 14 to the other side of the disc. The nut 3 secures the hollow shaft 2 to the centrifugal rotor. The air accumulates in the space 11 at a pressure determined by the position of the liquid level 10. One or more channels 12 extending axially through the nut 3 balance the air pressure above and below the nut. Impeller vanes are provided at 8. In operation, the contaminated liquid is pumped through the inlet 4 and air bubbles carried by it pass out of the channels 9 into the space 11. As the air pressure in the space 11 increases the level 15 of clarified liquid in the channel part 14 and the level 10 of contaminated liquid are displaced radially outwards until the level 15 reaches the radially external end of the channel part 14. As more air is fed to the space 11, a corresponding quantity is released from the channel part 14 and is discharged from the centrifuge with the clarified liquid. The air cushion which is maintained in the space 11 due to the outer ends of the channels 9 being always covered by liquid, prevents liquid fed through inlet 4 from passing directly into the clarified liquid. A springloaded valve adapted to open under a certain pressure and in a direction towards the outer end of channel part 14 may be inserted in the channel 13, 14.

Abstract: 1379791 Erecting overhead cables NIPPON KOKUYU TETSUDO 29 Feb 1972 [11 March 1971 (3)] 9307/72 Heading H2C An overhead catenary and trolley wire are installed simultaneously from a railway car 1 under a tension of 1,000-1,500 kg., thereby eliminating the need for tensioning after installation. Catenary 12 and trolley 13 wires are fed from drums 33, 34 to the tensioning means 9 which comprises (see Figs. 7-9, not shown) sets of opposed rubber rollers 38, the rollers in each row being coupled by gears (40) and one of each pairs of rows (through which pass cables 12, 13) being connected to an electromagnetic brake which controls the final tension in the wires. The free ends of the wires are connected to post 35. As the car moves forward from right to left (Fig. 3) an articulated detector 7 closes an electrical circuit on touching a suspending hook 42 actuating a control device which in turn operates a hanger supplying unit 10 (see Figs. 8 and 9, not shown) which supplies hangers as at 43, 43a when the car is a specified distance from the hook. As, the car advances further, a hanging device 11 is automatically put into operation. The device 11 consists of an arm 45 linked to arm 62 which is horizontally and vertically pivoted. To the arm 45 are fitted vertically-pivoted rollers 73, 73a and 74, 74a. The rollers 73, 73a, together with pulleys 44a and 44b at their lower ends are coaxially mounted within rollers 74, 74a and spring-loaded to project as shown. The arm 62 is swung horizontally, wires 12, 13 catching against the rollers, and then vertically to a height corresponding to the hook 42. This height is determined by the height to which arm 7 is raised. The wire 13 is caught on pulleys 44c, 44b, retracting rollers 73, 73a, as shown in the dotted part of the Figure, and freeing wire 12 now on rollers 44, 44a. In the raised position, the span 45 is inclined from the horizontal as viewed both from the side and behind the car (see Fig. 19, not shown). As the car moves forward, therefore, the wire is automatically caught on the hook 42 as required. The hanging device then retracts.
