Title: Improvements in or relating to servicing mechanisms for fluid-cooled nuclear reactors
Inventor: TAYLOR COLIN
IPC: G21C19/16
Filed: 1961-01-04
Abstract: 921,348. Servicing reactors. GENERAL ELECTRIC CO. Ltd. Jan. 2, 1962 [Jan. 4, 1961], No. 371/61. Class 39 (4). A servicing arrangement in which it is required to serve a group of eighteen fuel element channels 2 in a reactor core arranged on three circles of different radii centred on a control rod channel 4, Fig. 1, the arrangement utilizing a rotatable charge shoot having an articulated radially adjustable selector tube for engaging the ends of the channels, comprises an indexing member carried by the shoot and co-operating with sensing means within the reactor pressure vessel, the indexing member being coupled to a cam mechanism for radially adjusting the selector tube as disclosed in Specification 916,980, whereby as the shoot is rotated through intervals of 30 degrees the selector tube is automatically radiused to serve sequentially three channels situated, respectively, on the outer, middle and inner circles. The indexing member, Figs. 3, 4, 5, comprises a body 5 having a pair of spring-loaded plungers 6, 7, the plunger 6 carrying three stops 9 projecting through slots 10, four spring-loaded stops 11 being mounted in body slots 12. When the plunger 6 is raised, the stops 11 rotate under their spring-loading through 90 degrees from their projected position, Fig. 5, to their retracted position, Fig. 7. The sensing means comprises six vertical slots 15 around the control rod channel 4. In operation, the shoot is rotated to any one of six positions in which a channel 2 on the outer circle may be serviced and is then lowered, this movement being arrested by the stops 11 engaging the upper end of channel 4 at positions mid-way between the slots 15, Fig. 5, the cam mechanism positioning the selector tube to its outer radius. To service an adjacent channel 2 on the middle circle the shoot is rotated through 30 degrees and lowered whereby the stops 11 enter slots 15 and the shoot weight is taken by stops 9, the spring 19 loading plunger 6 being compressed so that stops 11 retract, Fig. 7. In this axial position of the body 5, the selector tube is moved to its middle radius by the cam mechanism. To service an adjacent channel 2 on the inner circle the chute is rotated through a further 30 degrees whereby the stops 9 enter slots 15, the stops 11 being ineffective since they remain retracted, this axial movement being arrested by a flange 16, Fig. 8. The selector tube is moved by the cam mechanism to its inner radius. To reset the indexing member to permit servicing of another channel 2 in the outer circle, the projecting pin 8 of plunger 7 is depressed, thereby pivoting the stops 11 and permitting them to be re-latched by the plunger 6 (Fig. 9, not shown). Specification 878,506 also is referred to.
Patent GB-985973-A (GB)
Title: Fault indicator
Inventor: PAPERT ALAN HARVEY
IPC: G08B23/00
Filed: 1961-01-04
Abstract: 985, 973. Annunciator circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 13, 1961 [Jan. 4, 1961], No. 373/61. Heading G4F. [Also in Division H2] A fault indicating arrangement comprises a plurality of glow-discharge paths and circuit means including a fault-responsive switch associated with each path and effective on operation to establish a glow-discharge in that path and then prevent or permit transfer of the glow-discharge to another path on the occurrence of a further fault so that a single indication of the first or last fault is given until the arrangement is reset. In the arrangement shown, the paths are the cathode/ anode paths of a multi-electrode gas-filled coldcathode glow-transfer tube 1 and the terminals A.... J of the cathodes C1...C10 are connected to a reset switch S1 and fault responsive switches S2...S10. Initially the glow-discharge is settled on the cathode C1 to indicate the absence of a fault by operation of the reset switch S1 to reduce the potential of the cathode to the potential of the HT- line and then, as a capacitor C charges up, to a more positive potential. The switch is then released and the capacitor C discharges through a resistor R. If a fault occurs resulting in the closure of one of the switches S2 . . . S10, then the associated cathode has its potential taken sufficiently negative through the capacitor C to cause the glow-discharge to be transferred from the cathode C1 to the cathode associated with the closed switch. The capacitor C charges up so that should a further switch close due to another fault, the cathode associated with the further switch cannot be rendered sufficiently negative for the glow-discharge to transfer and only the first fault is indicated. If it is desired that the last fault only should be indicated, the capacitor C and the resistor R are omitted. Reference is also made to the use of individual glow-discharge tubes such as neon lamps.

A method of continuously casting in a mould having a longitudinal taper converging towards its discharge end, which comprises casting and cooling at such rates as to form a crater shell extending a substantial longitudinal distance along the mould and positively pulling the congealed casting out of the mould to wedge the taper of the crater shell against the mould taper, thereby to plastically deform and draw said crater shell and to increase heat flow from the crater shell to the mould wall. The mould 13 is made of graphite with a compression-fitted reinforcing metal shell and is substantially as described in Specification 853,853, which is referred to, but has an internal taper which is greater than the taper of a corresponding mould operating at the same casting rate, so that the casting is " wire-drawn " as it is positively pulled through the mould. Other features of the apparatus, including the mounting of the mould for vertical reciprocation and of the ladle for tilting &c. are as described in the aforementioned Specification. The metal is poured into the mould through a stainless steel siphon 12, whose discharge end is provided with an overflow cup 42 to prevent loss of suction during a starting-up operation and entry of air into the discharge end of the tube. Surrounding the siphon tube 40 is a shroud 43 through which molten metal may be poured by overtilting the ladle 11, to melt out frozen metal in the siphon tube. The ladle may be swung in a horizontal plane so that the siphon tube may discharge into a slag pot while its discharge rate is regulated, whereafter it may be then returned so that the siphon cup 42 is registered over, and lowered into the mould. Specifications 853,854, 853,855, 903,233 and 903,234 also are referred to.
