Title: Improvements in or relating to liquid moderated nuclear reactors
Inventor: DEIGHTON THOMAS
IPC: G21C9/02
Filed: 1963-06-28
Abstract: 1,098,623. Reactors. BABCOCK & WILCOX Ltd. Sept. 28, 1964 [June 28, 1963], No. No. 25760/63. Heading G6C. [Also in Division F4] A reactor core comprises fuel, and a liquid moderator at a pressure within a range which is close to but below the thermodynamic critical pressure, and in a condition in which the rate of change of liquid density with pressure is high; the core is operated under simmering conditions, and as the fuel is consumed during operation, the operating pressure is reduced to increase the moderator density, and hence nuclear criticality is maintained. The moderator is preferably light water, which functions as the coolant, and which flows to a steam generating heat exchanger where heat passes from it to a secondary coolant, the steam generator may be located in the reactor pressure vessel. The core is totally immersed in the moderator water, and the small amount of steam generated by the simmering is static in a space above the core and within the pressure vessel. The water pressure is approximately 3200 p.s.i. and its density is about 20 lb./ft.<SP>3</SP> The core is operated in an under-moderated condition, so that a drop in pressure increases the moderator density and results in a higher heat output. The reactor is suitable for ship propulsion in that if the moderator is replaced by sea water following an accident, the excess moderation of sea water at its normal density and temperature renders the core sub-critical. Further control may be obtained with an absorbing type control rod, by varying in the moderator the quantity of additions such as heavy water or boric acid, or soluble poisons which are removed from the moderator as fuel is consumed.

Title: Improvements relating to electrical discharge devices
IPC: H01J19/68
Filed: 1929-08-28
Abstract: 319,686. British Thomson-Houston Co., Ltd., (Assignees of Charlton, E. E.). Sept. 26, 1928, [Convention date]. Vacuum tubes; low-pressure metallic - vapour apparatus.- Alkali metals are. localized in electric discharge devices by coating the anode or a carrier other than an electrode with a substance absorbing the alkali metal and releasing it on heating. Caesium and rubidium may be localized by a coating of a colloidal suspension of graphite in water. In a half-wave rectifier, Fig, 1, the inner surface of the anode 3 surrounding the filament 6 is coated with this suspension. The tube is evacuated and heated by high-frequency currents to tree metal parts of occluded gases and to liberate caesium from a mixture of caesium chloride and calcium in a nickel casing 10. The caesium cleans up residual gases, and the excess of caesium is absorbed by the coating inside the anode and is liberated during operation of the tube to form a metallic atmosphere. In a 3- electrode valve, the suspension is applied to two carriers secured to the filament leads and extending parallel to the limbs of the hairpin filament, caesium being liberated during operation of the valve. The Specification as open to inspection under Sect. 91 (3) (a) of the Acts states also that the suspension may be applied to the anode or the grid of a three-electrode valve and describes the following :-In a neon lamp for radio transmission of pictures, nickel or iron flat electrodes 22, 23, Fig. 3 (Cancelled), so spaced that the discharge takes place between their outer surfaces have their surfaces coated with the suspension. Caesium or rubidium are freed from a pellet 30 and are absorbed by the suspension and retained thereby during operation of the tube to lower the cathode drop and starting potentials of the tube. In a lamp used as a current or voltage indicator or for illumination, hollow, cylindrical, nickel or iron electrodes mounted side by side are coated externally with the suspension and contain caesium azide or a mixture of caesium or rubidium chloride and calcium, the suspension localizing the alkali metal under all conditions and preventing discoloration of the bulb. This subject-matter does not appear in the Specification as accepted.

Abstract: 1513944 Gas discharge display panels INTERNATIONAL BUSINESS MACHINES CORP 20 June 1975 [25 July 1974] 26266/75 Heading H4D [Also in Division H1] In a gas discharge display device comprising two flat plates 8 sealed together to enclose a gas discharge volume 5, at least one plate 8 being transparent, each plate 8 includes material 3 which provides a resistive electrical connection between the sustain voltage conductors 7 and respective adjacent pairs of isolated electrodes 2 arranged in adjacent rows on the plate and which define with the electrodes on the other plate, gas discharge sites. As shown in Figs. 1 and 3 each plate comprises a glass substrate 8 on which the parallel sustain voltage conductors 7 and the firing or extinguishing pulse supply lines 9 are formed by printed circuit techniques, these conductors 7, 9 being covered by a first dielectric layer 4 having locally limited zones 3 of low electrical conductivity formed by doping or diffusion. Rows of isolated circular electrodes 2 are formed on the dielectric layer 4 to overlie respective supply lines 9 which, on the two plates 8 combined, provide orthogonal coordinate addressing electrodes. The electrodes 2 are covered by a second dielectric layer 6, and each sustain voltage conductor 7 is resistively connected to two adjacent electrodes 2. The electrodes 2 may alternatively be disposed in a hexagonal pattern, Fig. 6 (not shown). In an alternative embodiment, Fig. 9, the substrate 8a of each plate is made of a resistive dielectric material and the sustain voltage conductors 7 and the electrodes 8 are formed in the same plane embedded in dielectric layer 6. The pulse supply lines can be arranged orthogonally to each other on both substrates 8a, or, as shown, the device may be pulse addressed by one or more conductive plates 15 that can be moved on the substrate surface to cause discharge at selected sites, e.g. as in a "light pen"-type control or telautograph process. For a rectangular array the addressing arrangement may comprise a row of plates 15 mounted on shiftable member 16 that is traversed in one dimension across the back of substrate 8a with a gap 51 therebetween which may be filled with a dielectric oil. Integrated circuitry associated with the coordinate addressing may conveniently be mounted on the back of the member 16.
