IPC: G21C7/12
Filed: 1961-08-22
Abstract: 939,973. Controlling nuclear reactors. ALLMANNA SVENSKA ELEKTRISKA A.B. Aug. 22, 1961 [Aug. 24, 1960], No. 30181/61. Class 39(4). Drive means for the control rod of a heterogeneous nuclear reactor comprises a motordriven screw-and-nut mechanism, means for holding the rod connected with the nut for its function as a regulating control-rod and for releasing the rod from the nut when the former is in its uppermost position, and electromagnetic means which hold the rod in this position in readiness for its function as an emergency control-rod. In the embodiment shown in Figs. 1 and 1a, the control-rod 1 in the form of a tube is supported by the nut 5 which has an inwardly projecting shoulder 24 resting upon balls 21 pressed outwards by levers 22 mounting pivots 23 which carry a ring 18 in recesses of which the balls 21 are mounted. A spring 19 is mounted between the levers 22 and a flange 17 on a supporting tube 16 which extends from the lower end of the nut 5, the supporting tube 16 thus carrying the ring 18. The nut 5 is threaded on a screw 4 driven by a motor 3 and is prevented from rotating with the screw 4 by splines 12 which extend through slots 13 in an upper magnetic part 14 of the control rod 1 into slots 15 (Fig. 3, not shown), in the inner wall of a surrounding tube 2. When the nut 5 is raised, it carries the control rod 1 to its uppermost position when the part 14 is opposite an electromagnet 8 which holds the rod 1 in position. Since the motor 3 is still rotating, the spring 19 is compressed and the levers 22 swing inwards to allow the balls 21 to move away from the shoulder 24. The rod 1 then acts as an emergency control-rod, interruption of the current to the electromagnet 8 releasing the rod which falls under gravity into the reactor. In an alternative embodiment (Fig. 5), the means for holding the rod 1 connected with the nut 5 comprises pawls 31 pivoted on a bearing member fixed to the supporting tube 16 and engaging recesses 26 in the nut 5. A sleeve 33 ensures that the pawls 31 are turned outwards when the rod 1 reaches its uppermost position.

Filed: 1929-10-04
Abstract: 343,426. Treating sewage. MOHR, O., 27, Adolfsallee, Wiesbaden, Germany. Oct. 4, 1929, No. 30201. [Class 111.] In an apparatus for the biological purification of waste water with the use of air injected into open vessels by compressers the interior of the vessel is substantially free from obstruction so that the waste water may circulate as well as the injected air and an impermeable, porous or permeable single or multi-part cover is provided in the aeration chamber. The cover is spaced apart from the walls of the chamber and is arranged above, below or at the water surface and is such as to retain the air therebeneath in the form of a cushion in contact with the waste water, air passing out therefrom by way of the pores in the porous or permeable cover or, in the case of an impermeable cover, through one or more air-discharge devices provided therein. The apparatus may be so arranged that the excess of compressed air beneath the cover escapes in the vicinity of the wastewater inlet or by way of the inlet itself in order to achieve intimate admixture of the air with the water. The water in the aeration vessel may be heated by hot-water pipes or by preheating the compressed air employed in the aeration. A cover c, Fig. 1, having ribs C floats on the surface of the water in an aeration vessel B, compressed air is introduced through the pipe G and escapes round the edges of the cover or through apertures D in the cover. In a modification, Fig. 6, a multi-part cover is provided, each portion c<1> of the cover having downwardly extending walls c<2>, c<3>, the wall of each portion of the cover nearer the water outlet b being deeper than that nearer the water inlet a so that the air escapes under the shallower wall in counter current to the flow of the water. An adjustable tube d, Fig. 4, adapted to control the extent of the air cushion may be provided through the cover c. Fig. 8 shows an apparatus in which an aeration chamber R<2> is disposed between a preliminary clarification chamber R<1> and a subsequent clarification chamber R<3> and is connected therewith by apertures n in the lateral walls of the chamber R<2> for the passage of the waste water, the mud from the pre- and postclarification chambers passing by way of hopper-like apertures q into a rotting chamber.
