Title: Arrangement for the current-limiting interruption of direct and alternating currents of high voltage
IPC: H01H9/54
Filed: 1972-07-24
Abstract: 1391106 Arcing preventing D KIND 24 July 1972 [24 July 1971] 34602/72 Heading H1N An A.C. or D.C. current interrupting arrangement has a common capacitor C connected in turn into each of a plurality of "commutating stages" which operate successively to reduce the current to be interrupted. In Fig. 3 the opening of a switch S1 causes an arc voltage which triggers a spark gap TFS1 so that the current is diverted from the switch S1 into the capacitor C which is charged. When the capacitor is charged the current is directed through a resistor R1 and a switch S2. Then the spark at the gap TFS1 is extinguished and the capacitor is discharged through a spark gap TFSe and a resistor Re. Now the switch S2 is opened triggering the spark gap TFS2, causing in sequence the capacitor C to charge through the resistor R<1>, the current to be diverted through resistor R2 and switch S3' the spark at the gap TFS2 to extinguish and the capacitor C to discharge. Then the switch S3 is opened to cause a spark gap TFS3 to spark over, the capacitor C to charge, the current to be diverted through a resistor R3 and the capacitor C to discharge. The three resistors R1 ... R3 are now in series across the open switch S1, the residual current through them being finally interrupted by means not shown. This arrangement may be modified so that the capacitor charged during the opening of one switch is discharged through the next switch, as it opens, in the opposite direction to the current to be diverted, Fig. 5 (not shown). A common "commutating" switch may be used in place of the switches S2, S3 Figs. 10, 11 (not shown). In further arrangements a common capacitor is used in conjunction with two seriesconnected switches which are operated successively, Figs. 6 to 9 (not shown).

Title: Method of preparing hollow type high density ceramic nuclear fuel elements
IPC: G21C21/06
Filed: 1960-10-14
Abstract: 915,438. Nuclear fuel elements. MITSUBISHI ATOMIC POWER INDUSTRIES Inc. Oct. 14, 1960 [Oct. 15, 1959; Sept. 19, 1960], No. 35330/60. Class 39 (4). [Also in Group XXII] A method of preparing a hollow high-density ceramic or cermet nuclear fuel element for a nuclear reactor comprises the steps of filling up an annular space 3 between an outer cylindrical sheath member 1 and an inner coaxial cylindrical sheath member 2 with a quantity of nuclear fuel material e.g. uranium dioxide and then sealing the annular space, filling up a central void portion formed inside the inner sheath member with a mandrel 7 and thereafter subjecting the assembly thus formed to rotary swaging to densificate and sinter the mass of the filled fuel material in high density. To prevent carbides from precipitating in the sheath members on rotary swaging the sheath members are formed of stainless steel containing not more than 0.02% carbon by weight, zirconium alloys, aluminium, aluminium alloys, magnesium alloys, niobium and niobium alloys. The sheath members are maintained in coaxial alignments by apertured annular supports 5. After the sheath members have been assembled and the end plug 4 and supports 5 secured in position the annular space 3 is filled with fuel material the assembly being vibrated to ensure a high bulk density. An end plug 6 which allows elongation of the sheath members during rotary swaging is inserted in the annular space 3 and the mandrel 7 is inserted within the sheath member 2. Cold swaging and hot swaging at a temperature ranging from 800‹ to 1100‹ C. gave the maximum swaged densities of the fuel material equal to 91% and 95% of the theoretical value respectively. After the swaging operation to produce a nuclear fuel element, as shown in Fig. 4, the mandrel is removed by melting or dissolving in a mineral acid. The mandrel materials are zinc alloys and magnesium alloys, aluminium alloys, tin alloys, nickel and its alloys, copper alloys, iron alloys, silver alloys, cadmium and its alloys and antimony and its alloys. Preferred examples are given in the Specification. Alternatively, the fuel element is filled with a nuclear fuel material formed of oxides, carbides or silicides of uranium thorium or plutonium or any mixture thereof.
