Title: Computer interrupt circuit
IPC: H03K17/73
Filed: 1967-02-08
Abstract: 1,149,221. Computer interrupt circuits. WESTINGHOUSE ELECTRIC CORP. 8 Feb., 1967 [1 March, 1966], No. 6054/67. Heading G4A. [Also in Division H3] Computer interrupt circuit for transferring interrupt information into a magnetic core simultaneously with a probe pulse voltage derived from a probe circuit, comprises a set winding on the core, a switch operative to switch on upon a predetermined voltage difference thereon, said switch being connected in series with the set winding, an input circuit for supplying information in the form of an input voltage, a charge accumulating circuit responsive to the input voltage to create a minimum voltage level, the accumulating circuit being in series with the winding and switch wherein means is provided responsive to the probe pulse voltage and to the minimum voltage for preventing the switch from being affected by the rate of rise of the probe pulse voltage, and for switching on the switch. A peripheral unit wishing to receive or send data applies a voltage to terminal 18, Fig. 2, causing a transistor to stop conducting. A capacitor 68 is charged to a level determined by a Zener diode 70. A tunnel diode 78 is supplied with current via a resistor 80 and also from a transformer 84 receiving computer probe pulses. Tunnel diode switching occurs when the input drive voltage reaches the predetermined operating level simultaneously with the application of a computer probe pulse. The tunnel diode switches to a high voltage state and activates a silicon controlled rectifier switch 66 to cause current to flow through coil 26 and change the state of the core 24. This creates a signal at the HIT terminals to set a flip-flop to which several of the cores are connected and informs the computer of an interruption. The computer can interrogate the cores in a predetermined order, returning the core to its previous state in the operation, and deal with the peripheral units in the predetermined order. The switch 66 remains conductive after the capacitor has substantially discharged and prevents the capacitor from being recharged thus preventing multiple core setting for a continuing single input voltage. When the input voltage is removed the capacitor is fully discharged via the transistor 14 and the switch is turned off. In Fig. 3, a three layer semi-conductor device 96 is used and conducts when the voltage at 99 added to the voltage valve of the probe pulse reaches the threshold level of the device 96 to cause the S.C.R. 66 to conduct. Again while transistor 14 remains non-conducting the S.C.R. remains conducting and the capacitor is prevented from charging however the device 96 is cut off. When the interrupt voltage is removed the S.C.R. is switched to a non- conducting state.

The fuel elements of a nuclear reactor are suspended, individually or as assemblies, from a support plate, the support plate having a common inlet opening for each of a number of groups of fuel elements; slots extend from each inlet opening to individual fuel element locations ; the fuel elements have recesses in their upper parts which correspond to the width of the slots. The fuel assemblies are thus packed closely whilst retaining adequate strength in the support plate. The invention is applicable to gas - cooled fast reactors using a downwards flow of gas into the core. Fig. 1 shows a portion of a support plate, which comprises identical top and bottom plates 1, 2, interconnected by side walls 3 to form a cellular structure in the complete plate. The fuel element or fuel assembly 10, Fig. 2, is supported by a member comprising two square section lengths 11, 12 and two larger circular sections 14, 15; these cross-sections are substantially smaller than the fuel element cross-section. Thus, in Fig. 1, each hole 5 large enough to receive the fuel element cross-section passes eight fuel elements through it to enter them in the core. Each fuel element is lowered until its square sections 11, 12 are engaged by the slots 6; the fuel element is transferred through the slots until it is correctly positioned, whereupon it is lowered so that circular stem portions 14, 15 engage the holes 7 in the plates 1, 2. In a modification, the double plates 1, 2 are replaced by a single top plate, and the bottoms of the fuel assemblies are steadied in a separate grid. In both cases, a fuel element having a modified shank is finally positioned in the large central hole of each group.
