Abstract: 1505615 Reactor vessels COMMISSARIAT A L'ENERGIE ATOMIQUE 21 July 1976 [24 July 1975] 30371/76 Heading G6C A liquid metal cooled fast reactor is thermally insulated by the provision, within an annular space 27, between the primary vessel 9 and an inner vessel 25 having a free upper extremity 26, of a plurality of superposed resilient heatinsulating elements 28. The elements 28 are each formed of two oppositely positioned L- section members 29, 30 which fit one inside the other to delimit a space filled with a flexible material 32, e.g. a stack of wire fabric, wire mesh or interlooped wire elements or a packing of steel wool, including a series of thin, parallel, metal plates 32a. The L-section members 29, 30 are provided at one end with an extension capable of engaging in the adjacent L-section member so as to constitute a completely closed, continuous assembly. Liquid metal, e.g. sodium, vapour and aerosols present within the inert gas, e.g. argon, layer 13 above the sodium level 12 are prevented from spreading to the annular space 27 and producing thermal short-circuits in the elements 28 by the following construction. The reactor vault roof 4 from which the primary vessel 9 is suspended is provided with a metallic lining 33 formed of shells 33a lining bores 6 in the roof 4 containing heat exchangers (7) and circulating pumps (8) (Fig. 1, not shown), a bottom lining plate 33b and a lateral shell 33c joined by a flange 33d to the primary vessel 9. Beneath plate 33b is a circular L- section member 34 for supporting a flange 35 extending from a thin-walled baffle-plate 36 accommodating a heat-insulating lining 14. Plates 37 applied against this lining are extended downwards by a baffle-plate 37a beneath the sodium level 12 to confine a limited space 38 for the inert gas. The baffle-plate 36 is provided with resilient heat-insulating elements 28a formed of interengaged U-section members. Similar elements 28b are mounted within the annular space 27a between the primary vessel 9 and the lining 33, being resiliently maintained against the elements 28 by a compression device 40. Elements 28b are also mounted on either side of a supporting unit 41 between the primary vessel 9 and an outer safety vessel or leakjacket 10. The free upper extremity 26 of the inner vessel 25 can readily be subjected to the dimensional variations imposed by thermal cycling during reactor operation.

Abstract: 854,012. Electrophotographic processes. AUSTRALIA, COMMONWEALTH OF. Sept. 24, 1958 [Oct. 1, 1957], No. 30566/58. Class 98(2) Electrically charged pigment particles for developing an electrostatic image are suspended in a non-inflammable carrier liquid consisting predominantly of a liquid chlorofluoro-hydrocarbon. Preferably the carrier liquid is either CC13F or CC12F, CC1F2 or a mixture of these or alternatively a small proportion of xylene can be added to either of them without increasing the fire risk. In the examples, particles of phthalocyanine blue are dispersed in one of these liquids and the particles are subsequently secured to a developed image bearing surface by a fixative spray or boiled linseed oil residue left when the carrier liquid evaporates. Alternatively, the pigment particles may be coated with a resin composition in a ball or roller mill before dispersion in the liquid. One component of the resin is or is made partially soluble so that the coating becomes tacky and secures the particle to the image surface. The other component increases the speed of the development process.

Abstract: 629,174. Transparent cables for conveying light by internal reflection. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 16, 1946, No. 30864. Convention date, Oct. 31, 1945. [Class 97 (i)] [Also in Group XL (b)] In a signal transmission system, electric signals from a plurality of sources are translated into modulated light signals of distinctive separable characteristics, which are transmitted through a light guide, emitted through a plurality of windows in the guide and illunuinate a plurality of photoelectrically-sensitive devices, each of which is selectively sensitive to a particular light signal, to produce an electrical output similar to the appropriate input signal. Fig. 1 shows a multichannel television distribution system wherein signals from antennµ 15, 16, 17 are demodulated by receivers 18, 19, 20, amplified, and the video signals are applied to modulate radiant energy sources 23, 29, 31 such as glow lamps, Kerr cells, or cathode-ray tubes. The modulated light passes through selective optical wavelength filters 41, 42, 43 to a light guide 36 consisting of a branched tube having a reflecting inner surface, or a rod of translucent or transparent material such as quartz or an acrylic or polystyrene resin. The light guide has windows 48, 49, 50, allowing the modulated light to pass through selective filters 61, 63, 69 corresponding with filters 41, 42, 43 and to illuminate photocells 58, 66, 73 feeding receivers 53, 54, 55, each comprising a video amplifier, a sync. separator, a deflection generator and a cathode-ray tube, to reproduce a picture corresponding to the signal received by the appropriate antenna. A light guide such as 62 may be interposed between window and photo-cell. In a modification (Fig. 2, not shown) the modulated light corresponding to a particular incoming signal is selectable by the interposition of one of a number of alternative filters between a light guide window and a photo-cell feeding a receiver and C.R. tube supplied with deflection voltages from a central source. Fig. 3 shows a device for transmission of sound or other intelligence wherein signals from a microphone or other source 96 are amplified and modulate the output of a light source 99 directed into a light guide 102 illuminating photo-cells 106, 107 through windows 103, 104. The photo-cell outputs are amplified and feed loudspeakers or other transducers 111, 112. In further modifications (Figs. 4, 5, not shown), electron multipliers replace the photo-cells, and cathode-ray tubes with different screen fluorescence colours replace glow lamps with optical filters.

Filed: 1924-12-24
Abstract: 245,583. Bovine & Co., Ltd., and Cook, H. D. Dec. 24, 1924. Regulating. - The angularity of the runner blades b of a highspeed water turbine is automatically adjusted according to the head of water, and also, if desired, according to the load. Float or other mechanism l, m, l<1> m<1>, n, o actuated by differences in level in the head and tail races operates a pivoted cam i bearing on a roller h at the end of a rod e. This rod e adjusts the angularity of the blades b directly or through a servo-motor. The usual governor-control may be superimposed by making the pivot member k of the cam i slidable and causing a pivoted cam s to bear on a roller q on the pivot member, the cam s being displaced by a governor-controlled servo-meter d. In place of the two cams i, s, a single governor-rocked cam r, Fig. 3, may be used, having its pivot displaceable along a curved slotway w by the float-displaced rod o. Alternatively, the rod o may displace the point of connection of the governor-displaced rod u. In a further modification, the pivoted cam has a warped surface and is bodily displaced to present different cam tracks.

Abstract: 743,163. Optical filters. FERNSEH GES. Nov. 9, 1953 [Nov. 7, 1952], No. 30943/53. Class 97 (1). A variable density optical filter is provided in a television camera having an adjustable iris diaphragm and comprises a layer of light absorbing liquid between transparent plates, the separation of which is variable to change the thickness of the layer of liquid. Preferably a change in the thickness of the layer of liquid 7 is accompanied by an equal and opposite change in the thickness of a layer of less absorbing liquid 14 so that the optical path length through the filter remains the same. As shown in Fig. 4, plates 4A, 4B are fixed and plate 5 is movable and separates the two liquids 7, 14, of the same refractive index. A free piston 15 separates the liquids in a cylindrical reservoir 21 and three micrometer screws 10 are rotated to move plate 5 by pinions 11 engaging gear ring 12. Rubber rings 13A and 13B allow for the movement of plate 5 and the liquid displaced thereby reaches or leaves the reservoir by tube 8A, 8B. In another form the cylindrical reservoir 21 may be replaced by a reservoir having elastic walls and the apparatus simplified by omitting the second liquid 14. The elastic reservoir may be a rubber bulb 9 connected to a capsule 6 like that used in aneroid barometers, in which the transparent plates 4, 5 are mounted or, as shown in Fig. 1, an elastic member 6 may connect the plates 4, 5 and the filter may be placed between lens 3 and photocathode 1 of an image storage tube 2. The shading distortion of the pick-up tube may be compensated by making the absorbing liquid layer non-uniform.
