Title: Improvements relating to nuclear reactors
Inventor: WRIGHT JAMES ROSTRON
IPC: G21C15/02
Filed: 1965-06-28
Abstract: 1,134,698. Liquid-cooled reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 17 June, 1966 [28 June, 1965; 20 Sept., 1965; 11 March, 1966], Nos. 27283/65, 40078/65 and 10922/66. Heading G6C. A device is positioned in a reactor fuel element channel to prevent reverse flow of the liquid coolant due to failure of a fuel element can causing release of fission product gases therefrom. As shown in Fig. 1 the core of a sodiumcooled fast reactor is supported from underneath by spaced plates 11, 12 forming therebetween a coolant inlet plenum 13. Tubes 14 connecting the plates 11, 12 have coolant inlet apertures 15, and another tube 16 within each tube 14 has corresponding apertures and supports a cup 21 through a spider 20. The cup 21 receives the lower end of a fuel element assembly (not shown). Each fuel element assembly comprises an array of pressure - resistant metallic sheathings, the upper half of each sheathing being filled with fuel material and the lower half providing a voidance space for fission product gases. To prevent reverse flow of the liquid coolant an hydraulic counterflow brake device 23 is positioned in the tube 16, this device offering little resistance to the normal upward flow but offering considerable resistance to reverse flow. The device 23 comprises a series of truncated conical sections 24 having scoops 25 into which the reverse flow is directed by baffle plates 26, these plates being connected by webs 27 to the conical sections. Alternative reverse flow restricting devices are described with reference to Figs. 2-8 (not shown), certain of these devices acting like one-way valves which automatically close to completely obstruct the reverse flow.

Title: Manipulating apparatus for the remote handling of objects
Inventor: HESSEN VICTOR BORIS
IPC: B25J19/04
Filed: 1958-08-26
Abstract: 874,495. Handling radioactive materials. PYE Ltd. Aug. 25, 1959 [Aug. 26, 1958], No. 27348/58. Class 39(4). A manipulating device having gripping tongs carried by a slave arm for handling radioactive material within a shielded chamber and hand grip controls mounted on a master portion for controlling the tongs, the slave arm following the movement imparted to the master portion by the operator, has a foot operated control for causing a further movement of the slave arm. This further movement is relative to the master portion. The drawing shows two manipulating devices each having three pedals. Thus, pressure by the toe on a central pedal causes forward displacement of the corresponding slave arm, pressure on the heel brings the slave arm back towards the operator, sideways pressure of the foot to the left causes lateral displacement of the slave arm to the left whilst sideways pressure to the right causes displacement of the arm to the right. The tongs may be viewed by television cameras, each camera being controlled by an outer pair of foot pedals. One pedal is arranged to control up and down tilt of the camera by means of heel and toe pressure and panning of the camera by side-to-side pressure of the foot. The other pedal of the pair controls the camera optical settings, i.e. toe and heel pressure controls focus, whilst side-to-side movement selects the setting of the lens turret. The arrangement permits the operator to remain seated. The pedal movements operate electric micro-switches to effect control of the manipulating devices. Specification 873,077 is referred to.

Title: Control mechanism for centrifuge discharge conduits
IPC: B04B11/04
Filed: 1927-10-15
Abstract: 280,180. Athenstedt, R. Nov. 4, 1926, [Convention date]. Density separators; treating substances with liquids.-The discharge from a centrifugal machine is led to either of two channels and is controlled by a valve operated by the control mechanism which also operates the valves controlling the admission of material and the admission of purifying fluid. The arrangement is for use particularly with centrifugal machines employed in the manufacture of sugar. The massecuite passes from the vessel a into a distributing vessel b having a valve d for each centrifugal machine; the valve is operated by a handle e which also operates an electric switch p. When a valve d' is opened the massecuite passes into the corresponding centrifugal separator c and the waste from the separator passes through the pipe f and the valve i to the channel g. The valve i can be lifted by the solenoid k under the control of the switch o, and then the passage to the channel g is closed and the discharge passes to the channel h. When the solenoid k is de-energized the valve i is moved down by a spring to re-open the passage to the channel g and to close that to the channel h. Washing water, to purify the top layer of sugar, is introduced into the drum through the pipe w controlled by a valve m operated by the solenoid n which is also controlled by the switch o. The switches o, p are interconnected so that the operations take place in proper sequence. To fill the separator c with massecuite, the handle e is lowered to open the valve d. This movement opens the switch p and the resultant changes cause the breaking of the - circuit of the solenoid k so that the discharge pipe f communicates with the channel g. When the machine is filled the handle e is raised to close the valve d and to close the switch p. The machine is then run as a separator and when the separator action is completed, the rocking arm of the water pipe w in the machine, and the switch o are operated The electric current energizes the solenoid n and opens the valve m to supply washing water, and the solenoid k is also energized to connect the discharge pipe f to the channel h. When the washing of the top layer of sugar is completed, the switch o is moved back to cause the valve m to shut off the supply of water. The solenoid k remains energized until the end of the centrifuging, when the machine is emptied and afterwards re-filled by the downward motion of the handle.

Title: Method for the preparation of copper sulfide films and products obtained thereby
IPC: C23C14/20
Filed: 1962-07-23
Abstract: A transparent electrically conductive film of copper sulphide is formed on a substrate by depositing a film of copper or a reactive copper compound on the substrate and then contacting the film with a sulphur-containing gas, which converts at least the surface of the film to copper sulphide.  The reactive copper compounds may be the iodide bromide acetate, sulphate, chloride, nitrate, or a chelate, e.g. of E.D.T.A., and are applied to the substrate by vacuum deposition, electrodeposition, or from suspensions.  Substrates specified are vitreous silica, or optically clear polymers, e.g. polyvinyl chloride or fluoride, polyvinylidene, polyethylene, esters, e.g. terephthalate, of 100m  thickness.  The copper sulphide film may be 10-1000m  thick. Suitable sulphur-containing gases are hydrogen sulphide or polysulphide, methyl mercaptan, dimethyl sulphide, thiocyanic acid, or heated ammonium sulphide. The gas is preferably applied to the heated substrate, and the copper sulphide film contains excess of sulphur and may include compounds ranging from Cu2S to Cu9S5.  Preferably the coating contains 0.7-1.4 mols Cu per mol of S to achieve adequate electrical conductivity. Forms of apparatus are described (not shown) in which a polymeric tape passes through a chamber where it is coated with copper by vapour deposition in vacuo; the copper source is removed, and the tape reeled with a kraft paper interleaving strip. The strip is then treated with H2S gas at 100-120  DEG C., the kraft paper giving good penetration into the copper coating. The product, which still retains a copper metal intermediate coat, may be used for recording. Details are given of optical and resistance tests with controls to provide optimum results.
