The lower ends of fuel element channels 5 (only one shown) in the reactor core 4 have extensions 17 leading to one of a number of selectors 16, each selector serving a group of channels, e.g. 315 channels, the lower ends 19 of the extensions 17 of a group being arranged on nine concentric circles each circle having thirty-five ends 19. A rotatable plug 20 in the selector has nine passages 21, the passage entries 22 lying on a common radius but the passage ends 23 each lying on a different radius corresponding to the radii of the circles on which the ends 19 are located. A lower rotatable plug 24 has a single passage 25 having a central entry 26 and an exit 27 lying on a circle having the same radius as that of the entries 22. The channel 5 to be loaded or unloaded is selected by rotation of the plugs 20, 24 and a flexible probe 14 is brought out from a dispenser 15 to support the lower end of the fuel elements 28. A charge machine 9 movable over the shield 3 is aligned with a selected hole 8 and standpipe 10 (only one hole and one standpipe being shown) and a pantograph 13 is lowered from the machine and extended to be in alignment with the channel 5 from which the fuel elements are to be discharged. The probe 14 then lifts the fuel elements 28 in the selected channel so that the upper fuel element is received in the pantograph 13, the latter being retracted so that the element may be lifted by a hoist into the machine 9. In a charging operation the process is reversed, the fuel elements being lowered singly into the pantograph which is then extended and the fuel element lowered into the channel by withdrawing the probe 14.

Abstract: 1,103,406. Thermal switches. ROBERTSHAW CONTROLS CO. 23 March, 1965 [April 20, 1964], No. 12323/65. Heading HlN. In a thermally responsive switch, the actuating and resetting means are so contructed and arranged that the contacts cannot be reclosed by the resetting means unless the temperature has fallen sufficiently. Housing 21 houses bi-metal disc 31, fixed contacts (41, 42, 43, 44), bridged by contacts 46, 47 urged into contact with the fixed contacts by springs 48, actuating member 49 extending between bi-metal 31 and bridging contacts 46 47 and reset member 53 comprising a pushbutton 54 and integral shaft having a slot (58) fitting over the actuating member 49. When disc 31 snaps over when the temperature rises to the predetermined value it moves member 49 opening the contacts. If the temperature has fallen sufficiently, when reset member 53 is depressed its end 57 bears on disc 31 causing it to snap back to its original position so that springs 48 reclose the contacts. If the temperature has not fallen sufficiently, when reset member 53 is depressed it forces disc 31 into a flat position, Fig. 9 (not shown), but since disc 31 does not snap over, member 49 maintains the contacts open. In a modification, only one pair of contacts is provided and the actuating member 49 is modified in shape accordingly.

Gear-cutting.-The bevel-gear cutting machine described in the parent Specification is modified so that the tool-carrying levers instead of being operated by a single taper cam are operated by two separate cams acting through tooth-proportioning levers upon pivoted runner bars engaged by rollers on the tool levers. The ram 1 carries a vertical slide 5 having a pivot 9 supporting the tool levers 7, 8. The tool levers carry runners 7<2> or 8<2> which are held by a spring-pressed plate 12 against respective runner bars 16, 16<1> which are supported on a bracket 14. At the front of the machine the bracket 14 is provided with a vertical extension 14<1> in which work sliding blocks 18, 18<1> adjustable by a right and left-handed screw 19 and carrying pivot pins for the ends of the runner bars. Templet cams 22, 22<1> mounted on a, shaft 23 and driven at the required. speed through gearing from a shaft 29 actuate the runner bars through tooth-proportioning levers 32, 32<1> pivoted to the bracket 14 and provided with adjustable contact members 34, 34'. By adjusting firstly the position of these members relatively to runner bars and secondly the distance apart of the runner-bar pivots, the same cams may be adapted to cut gears of different pitches and cone angles. In order to feed the cutters to give the required tooth depth while maintaining the cutting path in the direction of the blank cone apex a swinging slide 36 receives a runner 37 carried by the slide 5. The slide 36 is actuated against the action of a spring 42 by a runner 38 adjustably secured to a pivoted lever 39 .actuated through u rack 40 from a mutilated gear 41 on the cam shaft. When the cutting is completed the rack is released by the mutilated gear and the slide returned by its spring. The lower ends of the tool-carrying levers are steadied by the provision of projections working in a curved guideway 35, Fig. 3, in the slide 5 and carry adjustable slides in which toolholders 46, 46<1> are pivotally mounted so that the tools are relieved on the return stroke. As additional tool-relieving means the runners 7<2> and 8<2> may be provided with eccentric bushes having arms carrying pads bearing on the runner bars so that the tools are withdrawn and restored at opposite ends of the stroke.

Abstract: 528,213. Electric-battery lamps. STEELE, W. R. May 1, 1939, No. 12941. [Class 39 (ii)] [Also in Group XXXVI] A pocket testing instrument contains in combination a flashlight, a continuity tester, a voltage and polarity indicator, a resonance indicator, and an approximate indicator of frequency. Fitted within a tubular insulating casing 1 is a metal liner 2 screw-threaded at one end 3 to take a screwed metal sleeve 4 with an intermediate flange 5 which bears against the end of the casing 1. On the sleeve 4 is screwed a cap 6 open at its end 7. The sleeve 4 is formed with a socket 8 to take a flash lamp 9. Batteries 19 are placed within the cylindrical liner 2 with the centre terminal of one battery in contact with the centre terminal of the lamp. Contact with the outer terminal is made by a sliding metal strip having one end 21 bent inwardly and the other end carrying a button which passes through a slot in the casing. At the opposite end of the casing is an insulating plug 22, in an aperture in which is inserted a neon bulb 40 visible through openings in the casing 1. In the end of the plug is a metal insert 23 into which is screwed a testing spike 29. The inner end of this spike is tapered to fit a conical aperture in the insert 23 so as to grip the end of a flexible conductor 31 connected to a spring strip 35 which makes contact with the outer terminal of the battery and presses the batteries into contact with the centre terminal of the lamp 9. One terminal of the neon bulb 40 is connected to the strip 35, whilst the other terminal is connected, either directly or through a resistance 43, to a spring clip 45. A second testing spike 29<SP>1</SP> is carried by a high-tension flexible conductor 36 terminating in a button 37 which can either be inserted through a keyhole aperture in the casing to make contact with the metal liner, and therefore with the outer terminal of the lamp 9, or may be engaged under the spring clip 45 so as to make contact with one terminal of the neon bulb 40. A pair of spring clips 56, Fig. 4 (not shown), are provided for attachment to the spikes 29, 29<SP>1</SP> when required to clip on to a wire or terminal. With the button 37 inserted as shown in Fig. 1 the flashlamp 9 is used for testing the continuity of a conductor to which the spikes 29, 29<SP>1</SP> are applied. With the button 37 engaging the spring clip 45 the neon bulb indicates by the brightness of its glow the approximate voltage between points to which the spikes are applied and whether this voltage is A.C. or D.C. and its polarity. Frequency is indicated by the frequency of the flicker. The neon bulb may also be used for locating faults in radio testing, such as short-circuited condensers, or for resonance indications in radio equipment and wave meters.
