Title: Improvements in or relating to heterogeneous nuclear reactors
Inventor: BUTLER ALAN HENRY
IPC: G21C5/08
Filed: 1959-05-04
Abstract: 916,144. Moderator structures. GENERAL ELECTRIC CO. Ltd. April 29, 1960 [May 4, 1959; July 8, 1959; April 12, 1960], Nos. 15211/59, 23468/59 and 3037/60. Class 39 (4). A moderator restraint system includes adjustable assemblies of rollers or the like and links, each assembly engaging the core and an adjacent support structure so that forces applied to the assembly in a direction parallel to the axis of the core will cause the assembly to exert a substantially radial force on the core. The Figure shows a double series of linked rollers 11 alternate ones of which engage a core 1 and a support structure 7. An axial force is applied by piston 19 operated by reactor coolant CO 2 , backed up by oil-operated rams 22; damper valve 25 allows absorption of shock loads but permits thermal expansion and contraction of the core. Assemblies on opposite sides of the core are connected to prevent unbalanced loading. In another embodiment the rollers are mounted on radial bars fastened to the joints between links, so that restraint forces on the core are produced by tensional forces applied to the assemblies, instead of compressional forces.

Title: Improvements in or relating to process for preparing crystalline magnesia and resulting product
IPC: C01F5/06
Filed: 1953-06-03
Abstract: Periclase is formed by firing at at least 1300 DEG C. a mixture of a magnesium compound which yields periclase on firing, with an aluminium compound in an amount to provide up to 1.5 per cent of added aluminium, calculated as Al2O3 based on the fired product.  The magnesian starting materials may be magnesium hydroxide, carbonate, basic carbonate, alcoholate, sulphate, chloride, magnesite, brucite or cryptocrystalline magnesia, the latter being prepared for example by firing a magnesium carbonate, basic carbonate or hydroxide at 1200 DEG C. for 45 minutes.  The final periclase preferably contains at least 95 per cent magnesium oxide, and less than 2 per cent of each of calcium oxide and silica.  The aluminium compound added may be alumina, aluminium hydroxide, sulphate, chloride, or other halide, phosphate or sodium or potassium aluminate and the compound may be added in finely divided form or preferably, as a solution or dispersion in a liquid suitably water.  Aluminium bromide may be added in alcohol, carbon trisulphide or acetone.  Part of the added aluminium compound may be replaced by chromium or iron compound, the total amount of additives, as R2O3 being up to 1.5 per cent of the fired product by weight.  The mixture of magnesian materials and additives may be pressed before firing or fed directly to a kiln.  If desired a two-stage firing may be employed, the first at below 1300 DEG C., preferably below 1200 DEG C. to form cryptocrystalline magnesia, and the second at at least 1300 DEG C. and preferably at 1500 to 1750 DEG C.  The addition of the additives may precede either the first or second firing.  Also there may be admixed with the cryptocrystalline magnesia up to 90 per cent of finely divided well crystallized periclase, after which the mass is pressed and fired at at least 1600 DEG C. to obtain periclase.  Specifications 698,797, 711,908 and 758,089 are referred to.

Title: Improvements in the manufacture and production of valuable hydrocarbons
IPC: C10G47/00
Filed: 1927-06-09
Abstract: 302,253. Johnson J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 9, 1927. Hydrogenation, destructive. - Hydrocarbon mixtures boiling below 200‹ C. and consisting mainly of aromatic and unsaturated aliphatic and hydroaromatic compounds are obtained by acting on carbonaceous materials containing substantial amounts of non-aromatic hydrocarbons, e.g. coals, tars, mineral oils, pitches and their conversion products, at temperatures above 550‹ C. and at pressures above 20 atmospheres in the presence of excess hydrogen and preferably in the presence of catalysts. If the latter are used they should be of the kind exerting a "cracking" reaction, e.g. elements of the third and fourth groups of the periodic system and elements of the second group in conjunction with ruthenium chloride. Catalysts specified are aluminium hydroxide, bauxite, alderwood charcoal impregnated or not with phosphoric acid, Florida earth, bone charcoal, magnesia with 1 per cent of ruthenium chloride, copper oxide mixed with iron oxide, silver silicate, copper-zinc silicate, iron oxide mixed with vanadium oxide, titanic acid, manganous oxide, oxides of beryllium, magnesium, calcium, cerium; silica or diatomaoeous earth. Catalysts, e.g. molybdenum, which have also a dehydrogenating action should only be used so that their cracking properties predominate, i.e. by mixing them with compounds of elements of the second and third groups of the periodic system. Vapours of a heavy middle oil are passed with hydrogen which is employed about 20 times in excess over a chromium oxide catalvst heated to 575-600‹ C. under 200 atmospheres pressure. The gases leaving the reaction vessel are cooled and a product containing 85 per cent benzene and 5 per cent toluene and its homologues is obtained. Specifications 247,586, 249,156, 251,264, 258,272, and 281,298 are referred to.

Title: Charge detector
IPC: H01L29/768
Filed: 1972-04-04
Abstract: 1369520 Semi-conductor storage circuits INTERNATIONAL BUSINESS MACHINES CORP 4 April 1972 [3 May 1971] 15498/72 Heading H3T [Also in Divisions H1 and G4] The figures show the circuit and a plan view of part of a digital CCD system which employs an n-type semi-conductor substrate. Electrode 28n is the final electrode of a first CCD device the device having an output gate 29. Electrode 38 is the first electrode of a second CCD device, the device having an injector 16 and an input gate 37 the capacitance of which is denoted by C-4. The other components shown form an arrangement for detecting and regenerating the output signal of the first device in order to feed the second, some of the components being for resetting the arrangement. The input of the arrangement is provided by MOS capacitor C-2 (30) the capacitance of which may be increased by holes brought into its depletion region under the control of output gate 29. (C-2 comprises the oxide capacitance C-2<SP>1</SP> and the capacitance C-2<SP>11</SP> of the oxide-semi-conductor interface). In the absence of holes under final electrode 28n none can be transferred to MOS capacitor C-2 (30). Under these conditions IGFET 18 (31, 32, 33), the gate of which is connected to the junction of capacitor C-1 (34) and capacitor C-2 (30) is ON (a negative potential is connected between C-1 capacitor electrode contact 35 and earth) and the potential applied from the junction between the drain of the IGFET and its resistor 44 via capacitor C-3 (59) to the input gate 37 is such as to keep the gate closed and so prevent charge injection into the second CCD device. In the presence of holes under final electrode 28n these may be transferred to capacitor C-2 (30), increase its capacitance, thus turn the IGFET 18(31, 32, 33) OFF and let input gate 37 open to pass charge into the second CCD device. IGFETs 65, 67 with gates 69, 72 are used with power supplies 66, 68 to restore the original charge conditions in capacitors C-2 (30) and C-3 (59) so that the arrangement is ready for further operation. Figure 4 (not shown) depicts a variant in which the physical arrangement of capacitors C-2 and C-1 differs; C-1 (84) partly overlies C-2 (85). The detecting and regenerating arrangement is stated to be also of use in analogue mode and to be of use in conjunction with IGFETs whether or not these are provided with drain diffusions.

Abstract: 853,101. Coating by vapour deposition. MULLARD Ltd. Nov. 24, 1958 [May 15, 1958], No. 15651/58. Class 82(2) [Also in Group XL(a)] In a method of depositing a uniform photo-conductive target layer on the end face of an electric discharge tube e.g. a Vidicon television camera, an evaporator, which (as viewed from the end face) comprises openings and supporting surfaces for photo-conductive material both of which are uniformly distributed over a cross-sectional area of the tube which is approximately equal to the area of the target layer to be produced, is located within the tube envelope and heated in an inert gas atmosphere under reduced pressure. The evaporator may be a wire or narrow metal strip wound in spaced turns free from interruptions, e.g. in the form of a spiral, a helical spiral or in zig-zag fashion, and may be directly heated by induced currents or by passing a current therethrough. Alternatively the evaporator may be an apertured disc of glass, ceramic or metal and may be indirectly heated by a heater element in the form of a wire or strip wound in spaced turns free from interruptions and heated by induced currents or by passing a current therethrough. The photo-conductive material, preferably red antimony trisulphide, is provided on the evaporator by evaporation in a vacuum (Fig. 5, not shown). As shown, a spiral evaporator 5 is supported, 1 cm. from window 33, on conductors 41, 42. To improve the uniformity of target layer 53 the spiral may be wound tighter at the outside or a wire which tapers towards the inner end may be uniformly wound. The evaporation may be effected in argon from reservoir 40 at a pressure of a few mms. of Hg recorded by manometer 38, the tube having previously been evacuated by pump 36 to a pressure of 10-<SP>6</SP> mms. of Hg. A liquid air or oxygen trap may be provided immediately above the greased joint 34 to prevent grease vapour from entering the upper part of the tube. The window, which is provided with a thin transparent conducting film is cooled, by means of a cooling jacket 50 containing water, during the formation of the target layer. Specification 853,070 is referred to.
