Title: Process and apparatus for effecting nuclear fission reactions
IPC: G21C1/22
Filed: 1955-04-07
Abstract: 800,526. Nuclear reactor. STICHTING REACTOR CENTRUM NEDERLAND. April 7, 1955 [April 14, 1954], No. 10323/55. Class 39(4). A process of effecting nuclear reactions in a nuclear reactor, in which the atomic fuel circulates in the granular form through the reactor and subsequently through a heat exchanger, is characterized in that the atomic fuel is passed in granular form through the reactor by gravity, is discharged at the bottom and added to a gas stream, and subsequently, suspended in the gas, passed, via a heat exchanger, to the top of the reactor, where the solid matter is separated from the gas and again fed into the reactor. In Fig. 1 the reactor comprises a reflector 1, a chamber 2 for the moderator which may consist of heavy water, and reactor tubes 3 through which the granular fuel passes. The moderating heavy water may circulate through a heat exchanger (not shown) so that its temperature is kept sufficiently low. The walls of the tubes 3 may be of tightly sintered BeO, and if the moderator is heavy water the outside of the tubes should preferably be coated with a porous substance such as lightly sintered BeO. The tubes 3 debouch into vibrating vessels 4 into which gas, such as helium or carbon monoxide, is fed from a conduit 10 ; the gas entrains the fuel in the vessels 4 and passes it through a heat exchanger 15, where it gives up heat for example to a liquid metal, to hydrocyclones 17 which separate the gas from the fuel. The fuel is returned to the reactor and the gas passed through a purification device 20 and a pump 21 back to the vibrating vessels 4. In a homogeneous reactor, Fig. 2 (not shown), the tubes 3 are omitted and the chamber 2 is filled with a granular mixture of nuclear fuel and moderator, e.g., a mixture of granular uranium oxide and beryllium oxide. Apertures in the bottom of the reactor vessel discharge into vibrating vessels where the granular material is entrained by the gas and passed through a heat exchanger as in Fig. 1. Specifications 765,329 [Group XXX] and 779,826 [Group XIII] are referred to.

Abstract: 962,998. Matrix stores. STANDARD TELEPHONES & CABLES Ltd. March 15, 1963, No. 10372/63. Heading G4C. [Also in Division H4] In a matrix array, groups of storage elements are associated with auxiliary elements, each auxiliary element being set when the associated group is read, the auxiliary elements being subsequently read and an alarm given if any auxiliary element has not been set. The arrangement is applied to a matrix store used as a temporary store in a telephone subscriber's metering system as described in Specification 902,401. As shown, a matrix array FS has 1, 000 cores arranged in 100 rows and 10 columns, each core being set to "1" on receipt of an associated subscriber's metering pulse. Ten auxiliary cores CT1-10 are connected to the row wires of a selected ten of the 100 matrix rows and are set to "1" when the corresponding row is read. In operation, the rows of the matrix FS are scanned sequantially by an access switch AS, the reading pulse on a row wire of the matrix FS being effective to reset to "O" any core which has been set to "1", thereby producing a pulse on a column wire to set a corresponding bi-stable device M1-10. The bi-stable devices are reset sequentially after the scanning of each matrix row to provide via a bi-stable device X a serial pulse train which can be recorded. When the last matrix row has been read, a gate G2 is opened to read out the auxiliary cores CT1-10 into the bistable devices M1-10. The "A'' outputs of the devices M1-10 are connected to gates G4, Fig. 3, which are now enabled by a flip-flop Z, and if bistable device M1-10 has not been set, indicating that one of the auxiliary cores CT1-10 has not been set, an alarm flip-flop AL is operated. By operation of a TEST key and by removal singly and successively of bridge connections B1 &c., the alarm circuitry associated with the corresponding auxiliary core can be tested. In a modification, an auxiliary core is provided for each row, the cores being read out in groups of ten.
