Filed: 1967-10-25
Abstract: 1,157,037. Automatic exchange systems. INTERNATIONAL BUSINESS MACHINES CORP. 25 Oct., 1967 [28 Oct., 1966], No. 48431/67. Heading H4K. At each cross-point of an electronic cross-point switch, a pair of row conductors of the same line can be connected to a pair of column conductors of another line by a pair of controlled semi-conductor devices and the pairs of conductors are cross-coupled through identical semi-conductor devices connected so that they cannot become conductive. The semi-conductor devices may be thyristors or field effect or other transistors. The non-conductive semiconductors balance the capacitance of the active semi-conductors and reduce noise. The semi-conductors at each cross-point should be matched and may be batch manufactured, as, for example, integrated circuits. A thyristor arrangement in which the active thyristors of a row line have their control electrodes connected through diodes to a control potential source, and the non-conductive thyristors have their control electrodes connected directly to their emitters is detailed.

Apparatus for recording the thickness of the wall of a metallurgical furnace 1 (Fig. 1) comprises a plurality of electrically conducting loops 3 embedded in the wall of the furnace in staggered relation to one another so that when the furnace wall wears away by a determined amount the loop projecting furthest into the wall melts and gives an indication to a remote detector, a switch then being effective to connect the detector to the longest remaining loop. When the loop 3 closest to the furnace lining is fused, the voltage drop across a resistance 6 is removed and a relay 7 de-energized to operate contacts 7a, 7b to step a stepping relay 5 so that by the current flow through the next loop 3 the voltage drop across the resistance 6 is restored. Operation of the contact 7b produces a current impulse to step a relay 8, individual contacts of which are connected to the voltage tap of a voltage divider 9 so that a voltage representing the thickness of the lining wall is fed to a voltage recorder 10.

Title: Spacing grid for nuclear fuel rods
IPC: G21C3/332
Filed: 1972-11-03
Abstract: 1357055 Fuel elements BELGONUCLEAIRE SA 3 Nov 1972 [4 Nov 1971] 50828/72 Heading G6C A spacer grid for maintaining in position the fuel rods 9 of a fast breeder reactor fuel assembly includes a peripheral flared skirt 2, the free extremity of which contacts the internal wall of the shroud tube 4 of the fuel assembly. The skirt 2 ensures permanent contact between the grid and the tube 4 should differential expansion occur. Coolant flow (in the direction of the arrows 5) in the peripheral channels of the fuel assembly is only slightly modified by changes in the spacing between the grid and the tube 4 owing to the hydraulic obstruction caused by the flared skirt 2. The grid is supported by three tie-rods 14 (only one shown) to which it is connected by welding. The grid cells, hexagonal in cross-section, each include three hemispheric dimples 12, obtained by stamping the strips 11 forming the grid, and spaced by 120 degrees from one another. The structure formed by the strips 11 is then welded to a peripheral belt comprising a vertical part 7 of the same height as the strips 11 and an outwardly flared part part forming the skirt 2. The skirt 2 is maintained in contact with the tube 4 by a combination of elastic and hydraulic effects. The skirt further comprises dimples 13 facing each fuel rod 9 to avoid any accidental contact between the skirt 2 and the rods 9 during manipulation and irradiation of the assembly. In the six corners of the hexagonal grid, the skirt is cut out over a certain length so as to allow for suitable cooling of the corner fuel rods. The coolant flow round the tie-rods 14 between the successive grids in the assembly is adjusted with the help of sheaths 17 which comprise openings 18 allowing the passage of a small coolant flow. In alternative embodiments, the extremity of the skirt is either welded to the tube 4 or introduced into a slide attached to the internal wall of the tube 4.
