Title: Process and apparatus for shutting nuclear reactors down in an emergency
IPC: G21C7/22
Filed: 1972-03-17
Abstract: 1353122 Controlling reactors KERNFORSCHUNG mbH Ges FUR 17 March 1972 [23 March 1971] 12486/72 Heading G6C The emergency shut-down of a nuclear reactor is effected by the rapid injection of a neutron absorber into the coolant before its admission into the fission zone, the resulting shut-down being maintained by the addition to the coolant circulation before the coolant enters the fission zone of a predetermined quantity of absorber per unit volume of coolant. It is advantageous in Na-cooled reactors to use Li, more especially Li-6, Rb or Cs as absorber. A number of injectors 11 are located in fuel element positions spread over the cross-section of the fission zone 12, each being filled with an absorber within a storage space sealed at its lower end by a metal diaphragm 16 and at its upper end by a piston (17) (Fig. 2, not shown). The piston is held by means of an electromagnetic holding device (21) against a pre-compressed spring (22) so that when the holding device is released, the piston is forced down and the absorber ejected through the broken metal diaphragm 16 to enter the coolant flow through openings 23 in the lower end of the injector 11. A storage container 2 for an absorber is located in the lower part of the reactor pressure vessel 1 and includes a number of venturi tubes 3 through which the coolant passes on its way from the inlet pipes 4, 5 to the upper part of the vessel 1. Each venturi tube 3 is connected at a location at which there is maximum flow velocity, via a pipe-line 6 and a magnetic valve 7 closed during normal operation, to the interior of the container 2. On opening the valve 7, absorber is extracted by suction from the container 2 via the pipe-line 6, while a corresponding volume of coolant is introduced into the container 2 via another pipe-line 8 and magnetic valve 9. The magnetic valves 7, 9 may be extracted from the vessel 1 for maintenance by means of removal devices 10.

Title: Arrangement for the balancing of electrodes of electrical arc furnaces
IPC: H05B7/10
Filed: 1938-04-26
Abstract: 508,900. Servomotor control of electrodes for electric-arc furnaces. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. April 26, 1938, No. 12499. Convention date, Sept. 17, 1937. [Class 135] The electrode 1 (or both electrodes) of an electric arc furnace is controlled automatically by a hydraulic regulator or regulators such as 41, 43 to maintain constant certain working conditions and in order to balance the electrode a chamber 32 in a hydraulic cylinder 3 for effecting the automatic control, is connected by the regulator to a pressure tank 9 in which is maintained an approximately constant pressure sufficient to balance the electrode. When the normal current is consumed by the furnace, the only pressure in the chamber of the cylinder 3 is that in the pressure tank and this pressure is such that the electrode can slowly move towards the other electrode or a work-piece. Any increase in the current consumption attracts a member 411 in the part 41 of the regulator and opens a valve 412, thus relieving the pressure supplied from a tank 5 through a pipe 44 and the part 41 to the part 43 of the regulator. The relief of the pressure enables the piston 431 of the part 43 to move to the left and out off the tank 9 from the chamber of the hydraulic cylinder and pressure from the tank 5 acting through pipes 34, 33 then raises the electrode to its correct operative position. To keep the pressure in the tanks 5 and 9 at the required value, automatic regulators, shown diagrammatically at 6 and 10, are employed. If the voltage falls to too low a level, a relay 42 operates with the part 43 to lift the electrode. In this case, a member 421 is normally attracted, but when the voltage falls, this member is released and a valve 422 is opened so that, as in the case of current control, the pressure on the part 43 is relieved. Specification 222,573, [Class 135], and U.S.A. Specification 1,562,204 are referred to.

Filed: 1974-03-21
Abstract: 1486271 Data store INTERNATIONAL BUSINESS MACHINES CORP 21 March 1974 [30 March 1973] 12735/74 Heading G4C Binary data is stored, retrieved, and erased using a storage material which, at least at its surface exists in semiconductor and metal phases, the data being stored by inducing a metal to semiconductor phase transition by reducing the internal stress in the material at the desired location below a first threshold value, the data being retrieved by optically distinguishing between the two phases, and the data being erased either in bulk or at selected locations by inducing a semiconductor to metal phase transition by subjecting the material to an internal stress above a second threshold value greater than the first threshold value. The storage material may be samarium sulphide and reading, writing, and erasing is performed using a laser. Figs. 1-6 (not shown) illustrate schematic embodiments in which, e.g. the storage material is bent so as mechanically to stress the material to a point intermediate the two thresholds. Data is then written, read, and erased by the selective use of two lasers, one of high power and one of low power, the high power laser being used to stress the storage material above the second threshold to erase data and the low power laser being used to read data and to reduce the stress below the first, low, threshold to write data. Alternatively erasure may be performed by polishing or bending the material. Two practical embodiments are described. In the first, Fig. 7, a stationary disc 23 of storage material is used in conjunction with a beam deflector 25 to selectively access desired locations on the disc using beams from a read/write laser 31 and an erase laser 33. In the second Fig. 9 (not shown) a rotating disc is used together with a radially movable head incorporating the lasers. In the latter case each data track on the disc includes two adjacent tracks, one for the stored data and the other on which the erase beam is directed to erase data from the adjacent data track. It is also stated that ultrasonic vibrations may be used to erase selected locations in the storage material.
