Patent GB-1124135-A (GB)
Title: A nuclear reactor fuel element including a thermionic conyerter diode
IPC: G21C3/40
Filed: 1965-11-26
Abstract: 1,124,135. Nuclear power plant. SIEMENSSCHUCKERTWERKE A.G. 26 Nov., 1965 [26 Nov., 1964], No. 50467/65. Heading G6C. In a nuclear reactor fuel element, a thermionic emitter is heated by the fuel. A gap separates the fuel and emitter to permit fuel thermal dimension changes to occur without distortion of the emitter surface. To provide a thermally conductive path between the emitter and fuel, the gap is filled with corrugated metal foil or a mass of metal filaments. In an alternative form, the fuel may be in particulate form within the emitter mass. In the latter instance, prior to use, the temperature of the assembly is raised above the normal operating temperature. As the thermal expansion coefficient of the fuel particles is greater than that of the emitter material, displacement of the emitter material surrounding the particles takes place. Upon cooling the assembly, the fuel particles contract and cavities remain between the particles and emitter. This method may be facilitated by mixing beryllium oxide with the fuel and employing the phase change in the beryllium oxide.

The fuel, which may be pulverized coal, is blown into the bed through radially directed jets 24 connected to a ring main 25. Excess bed material spills through openings 22 and is removed by suction through pipe 21. The combustion unit may have on top of it a unit 19 having an exit 18 for the combustion gases and a number of heat exchange pipes 11 for heating air entering at 7 and leaving at 8. The combustion gases are cleaned in a unit (Fig. 2, not shown) consisting of a number of cyclones or filters which separate dust and carbon particles and pass it through a toothedwheel feeding device to an air injector which returns it to the bed via the fuel main 25. The injected air may be hot or cold. If hot it is the air heated in the section 19. The cleaned gases return through a port 17 in an economizer section 14 where heat exchange pipes 13 remove further heat before it passes to the flue 12. The fuel may alternatively be oil or coal dust mixed with oil pumped through the main 25. The distributer plate 34 supporting the bed, turns on bearings 28 and rotates the whole bed. The air supply to the bed may be adjusted to control the heat generation or part of the plate 34 may be covered by a stationary shutter causing the bed to collapse in that region.

Abstract: 1,248,227. Magnetrons. GENERAL ELECTRIC CO. 29 Oct., 1968 [14 Nov., 1967], No. 51292/68. Heading H1D. In a re-entrant stream crossed-field discharge tube in which axially propagating waves are generated, generally of the type disclosed in Specification 1,184,371, the cavity formed by the end spaces 55 and 57 with the interaction space 38 bounded by the inner surface 37 of the anode structure and the surface 45 of the cathode is arranged to have a resonant frequency equal to that of the folded transmission line formed by the anode members shown in Fig. 3, whereby efficiency is increased by the balancing of the R.F. voltage on the cathode with respect to that on the anode structure. In operation, axially propagating standing waves are generated which are reflected at the two ends 21, 29 of the outer annular cavity 35, pass through the radial passage 39, and are again reflected at the upper and lower open ends of the transmission line formed by the anode members of Fig. 3. The emissive coating on the cathode is provided with axially extending projections (Fig. 4, not shown) opposite the members 37 of the anode structure, and is radially stepped as shown in Fig. 2. At the upper end of the cathode, the cathode stud 43 is mounted within an insulator 62 which spaces it from a surrounding conductive tube 61 which is brazed to the pole plate 54 and hence is electrically connected to the anode structure to the outer conductive members 72 and 76, and hence to the T-shaped conductor 78. As shown in Fig. 1, the axially extending portion of the coaxial line coupled to conductor 78, and the shortcircuited arm 81, 91, are both arranged to be #/4 long at the operating frequency, while the remaining arm 87 couples the device to a load. The cathode and its heater 47 are also dimensioned to constitute a coaxial transmission line of effective length #/4, the line being closed at its upper end by an end plate 41 and the cathode stud 43, and coupled at its lower end to a further #/4 length of coaxial line formed by the heater connection 44a and a surrounding tube 94, which is insulated from the magnetic core by a plastics tube 95. This arrangement of the cathode and its heater, and of the external connections thereto, increases efficiency by minimizing losses due to circulating currents in the device. The casing 75a surrounding the device and connected to the polepieces is of magnetic material e.g. soft iron.

Title: Signalling apparatus for use in controlling the movement of pelagic fish
IPC: A01K79/02
Filed: 1972-11-10
Abstract: 1406828 Controlling the movement of seafish NEW ZEALAND INVENTIONS DEVELOPMENT AUTHORITY 10 Nov 1972 [15 Nov 1971] 52066/72 Heading A1A [Also in Division G4] Apparatus is used to control the movement of pelagic fish by either attraction or repulsion to or from the apparatus by means of suitable audible signals reproduced from magnetic tape, amplified and fed into an acoustic transducer. The apparatus is carried in a fishing vessel with the transduced submerged during operation. The control box 1 contains a multichannel cartridge tape recorder with associated high fidelity amplifiers and control gear and is connected to the acoustic transducer 2 by a coaxial cable. Power, normally from a 12 volt wet cell battery, is supplied via cable 12 and is monitored by voltmeter 4. The required channel of the recorder is selected by switch 5 and indicated by lamps 6; each channel has two tracks, selected by switch 7. The power supplied to the transducer is adjustable with gain control 8 The amplifier supplies at least 1 watt and in the preferred embodiment has a maximum capability of 20 watts.  The transducer 2 is a disc diaphragm, moving coil unit and preiferably has directional properties to enable it to, be used as a receiver for detecting fish. In the principal use of the apparatus, sounds known to attract fish are recorded on one track of each channel and sounds known to repel fish are recorded on the other. By selecting the channel appropriate to the particular type of fish, control of their movement is achieved by suitable switching between tracks. When the apparatus is switched to the receive mode by means of switch 9, the input of the main amplifier is connected to the transducer while the output is connected to loudspeaker 10. The directional properties of the transducer can then be used to determine the direction of the fish noise, making use of the rotational freedom between the arm 14 carrying the transducer and the sleeve 17 attached to the clamp 15 which is attached to the guard rail 16 of the fishing vessel. The process is facilitated by a bearing indicator 20.  The transducer may be lifted clear of the water by swinging the arm 14 about the horizontal pivot 18.
