Abstract: 947,217. Fuelling reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. May 9, 1960 [May 19, 1959], No. 16298/60. Heading G6C. In a refuelling arrangement in which a rotatable plug 6 is eccentrically mounted in a larger rotatable plug 5 so that a fuel element handling aperture 9 in the plug 6 may be moved above the reactor core 1, a handling plug, Fig. 2, is inserted in the aperture 9 after removal of a solid plug (not shown). The handling plug comprises a biological shield part 54 from which downwardly extends a fuel element guide skirt 22a, a casing 55 extending upwardly from the skirt containing a cable winder 24 driven by a motor unit 23. The winder cable 32 extends through a liquid seal bath 34 and a non-rectilinear passage in the shield part 54, the cable being guided by rollers 37 . . . 43 and carrying at its lower end a grab 31 for engaging the head 20 of a fuel element 19. The handling plug enables a fuel element to be raised to the position shown in Fig. 2 in which it is still immersed in the reactor coolant 21. A refuelling machine 13 for extracting a solid plug from the aperture 9 and inserting a handling plug comprises a mobile carriage 14 and a lead tower 15 enclosing a magazine 16 having three compartments, each compartment including a winch 17 and cable 18. Initially, one compartment is loaded with a handling plug coupled to a new fuel element and another compartment is loaded with a free handling plug. In operation, the machine 13 is moved over the reactor shield 4 so that the empty compartment of the magazine 16 may be aligned with the aperture 9, this aperture having been previously aligned with the fuel element 19 to be removed. The solid plug (not shown) in this aperture is withdrawn into the magazine by a winch 17 and the magazine rotated so that the free handling plug may be lowered by the cable 18 into the aperture, the plug skirt 22a passing through a skirt 22 attached to the plug 6. The winder 24 on the handling plug is operated to raise the fuel element 19 to the Fig. 2 position and the cable 18, which is engaged with a coupling 50 on the handling plug, lifts this plug together with the suspended fuel element into the magazine. The magazine is further rotated so that the handling plug coupled to the new fuel element may be lowered into the aperture and the fuel element lowered into the reactor core 1. The handling plug is then replaced by the solid plug in the magazine and the machine 13 moved to a deactivation pit 10 where the handling plug coupled to the spent fuel element is unloaded. In a modification (Fig. 4, not shown) the winder 24 is situated above the unit 23 whilst in a further modification (Fig. 5, not shown) the cable 32 is replaced by a metal tape.

Abstract: 317,566. Hale, G. W., and Radio Instruments, Ltd. June 5, 1928. Thermionic amplifiers ; aerials.- The output leads from the final valve in a receiving set are coupled back, either electrostatically or magnetically, to the input of the first valve, and so serve the purpose of an aerial. As shown in Fig. 1, a lead 12 is taken from the secondary of the output transformer 11 feeding the loudspeaker 10 to a terminal 13, which is then bridged by a fitting 14 to the normal aerial terminal 15 on the set. The connection to the tuned input circuit 17 is completed through a condenser 16. A counterpoise earth is secured at a point 31 between two condensers shunted across the supply mains 30. Both high and low tension are drawn from an eleiminateor 36, the fiilament circuit comprising series resistances 37 - - 41 which provide suitable grid bias for the various valves. Resistances 34, 35 are inserted in the grid circuits of the low-frequency amplifiers 2,5, 28, and condensers 42, 43 across the coupling transformers serve from reaching the output circuit, and so getting back to the input. Alternatively, the lead from the output back to the aerial terminal is tapped from between two condensers shunted across the last output transformer, or across a pair of high-frequency chokes 48, Fig. 3, in an output filter circuit, so as to prevant low-frequency voltage fluctuations from being imposed on the aerial or input. On one of the output leads may be connected directly to the tuned input circuit. Fig. 5 shows another magnetic coupling, chokes 48 in series with each output lead from the valve 28 being closely coupled to the input circuit 17. An external aerial and earth may also be connected as shown.

Title: Improvements relating to powder packing machines
IPC: B65B1/24
Filed: 1941-12-22
Abstract: 553,757. Moulding powdered material. SOUTHALL & SMITH, Ltd., and GWILT, C. Dec. 22, 1941, No. 16467. [Class 87 (ii)] A machine for packing a receptacle with powdered material such as explosives or drugs comprises a holder for the receptacle, a horizontal plunger n, a container v for the powdered material arranged beneath the plunger and an oscillatory or reciprocatory feeder y arranged in the container and adapted to lift successive quantities of material to a position from which they can be transferred to the receptacle by the plunger. As shown, the container is a disc-like metal body b having a central aperture therein which is to be packed with powder. During packing, the body b is pressed by a movable plate a against a fixed member c forming part of the container v, the hole in the body b registering with a hole d in the member c. The plunger n extends coaxially through a carrier o which is reciprocated via bell-crank lever q from a cam r. The lever q is loaded by a weight t, or by a spring. The feeder y is carried by an arm z on a shaft 2 oscillated by a face cam 4, and slides in an arcuate guide channel 9 in the member c. A powder-agitator 10 is reciprocated via a rod 11 from a cam 14. The cams r, 4 and 14 controlling the plunger, feeder and agitator are secured on a shaft 15 driven through a clutch having a radially-projecting control member which, when arrested, disengages the clutch which, upon release of the control member, is re-engaged by spring action. Operation :-When the machine is idle, the clutch-control member is held in the arrested position by an abutment 16 on a lever 17 pivoted at 18, the lever having been turned anticlockwise, from the position shown, by a spring 19. To start the machine, a hand lever 23 is rocked clockwise and, via axially slidable rod 24, rocks clockwise a lever arm 28 pivoted on shaft 27. The lever 28 rocks clockwise the lever 17, thus releasing the clutch-control member. As the plunger advances, the lever 17 is restrained in the position shown by an adjustable stop 21 on the carrier o, and as it recedes it is restrained by a cam 20 secured to the shaft 15. As the resistance of the packed material to the plunger increases, the forward movement of the plunger and carrier decreases until the stop 21 assumes a position clear of the adjacent end of the lever 17 when the latter is allowed to move by the cam 20: the said end then moves upwards, the abutment 16 engages the clutch-control member, and the machine stops. To locate the body b between the abutments a, c, the plunger is initially advanced so that it projects through the hole d, the body b being then threaded thereon. For this purpose, the operator rocks anticlockwise the lever 23, thus moving the rod 24 to rock a lever arm 34 which abuts the rear end of the plunger and thrusts it forward against the action of a spring 31 in the carrier.

Title: Electron multipliers
IPC: H01J43/24
Filed: 1973-04-06
Abstract: 1434053 Electron multipliers; electrode materials; cathode-ray tubes MULLARD Ltd 7 Dec 1973 [6 April 1973] 16541/73 Heading H1D A dynode for use in a channel plate has secondary emissive multiplier apertures which apertures in axial section are concave with overhang 01 at the input and a constriction 02 at the output face so that the input and output areas are smaller than the area of the apertures in a plane parallel to and between the input and output faces, the constriction being of gradually tapered form so that the multiplier surfaces converge towards each other in the direction of the output face. The construction counters penetration of a retarding field into each aperture. The apertures may be symmetrical about a median plane in axial cross-section, and input and output diameters or widths may be equal to each other or the thickness of the dynode. If the apertures are circular in cross-section, the inner surfaces may be spherical or spheroidal (Fig. 4, not shown) or made up of conical sections. Apertures may be square or hexagonal, e.g. in Figs. 4-5, these may be square with four cylindrical walls and Fig. 9 may have pyramidal apertures of square cross-section. A method of manufacture includes forming two perforate mating sheets (e.g. by photoresist techniques) and bonding together. The sheets may be colour TV shadow masks, the output halves treated to be secondary emissive. Dynode materials may be BeCu alloy, or mild steel coated with secondary emissive oxidized BeCu film or MgO. BeCu dynode halves may be bonded by a Cu-Ag eutectic braze, one half, preferably the input half, then Ag plated, both clamped together and then heated. Laminated assemblies may have slightly conductive, resistive or insulative separators (e.g. Figs. 7, 8, not shown), dynode M(1) opening towards the input direction. Separators may be discontinuous (e.g. lines or dots). Separator layers may be deposited on the half-plates, but are preferably continuous sheets etched via the dynodes. Mild steel halfplates may be glass coated by enamelling or electrophoresis, or a glass loaded adhesive tape may be heated to a vitreous form and etched via the dynode apertures, the remaining glass subsequently serving to bond the half-plates on heating. The stack may then be fixed by Au diffusion bonding. The dynodes may be staggered continuously (Fig. 10, not shown) and may provide curved channels. A thin layer or membrane may be across an end of each channel, e.g. a photoemissive layer as in patent Specification 1,154,515, or a conductive membrane as in patent Specification 1,175,599. Imaging and display applications are instanced, e.g. image intensifiers (X-ray) of proximity type (Fig. 11, not shown), colour displays as in Specifications 1,402,548 and 1,402,547 and TV displays as in Fig. 12 (not shown) with plate (I) and luminescent screen (S) on a flat glass window or support W, or on a curved faceplate F, in which case plate I is also curved. References are included to other U.K. Specifications.
