Title: Improvements in or relating to nuclear reactors
Inventor: HACKNEY STANLEY
IPC: G21C13/093
Filed: 1962-01-22
Abstract: 1,003,826. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY LONDON. Jan. 9, 1963 [Jan. 22, 1962; July 5, 1962], Nos. 2334/62 and 25786/62. Drawings to Specification. Heading G6C. In a boiling water reactor, pressurized light water and boiling light water are used jointly as a moderator and as primary and secondary coolants respectively in separate circulating systems. The primary coolant isolates the fuel from the boiling water. Slight boiling of the primary pressurized coolant is permitted to cause turbulence and thereby an increased rate of heat transfer to the secondary coolant. To prevent complete loss of the secondary coolant in the event of a failure in the secondary coolant circuit, a series of non-return valves prevent emptying of the fuel chamber. The upper section of the pressure vessel contains the secondary circuit steam separators and scrubber units and primary coolant pumps. The latter circulate the primary coolant through the fuel tubes and a pressurizer having a gas atmosphere. Each vertical fuel tube encloses a fuel assembly at its lower end and is connected at its lower and upper ends to adjacent tubes to permit the primary coolant flow. The primary coolant flows through the core in ten separate paths so as to effect a uniform distribution of heat across the core cross-section. Specification 981,423 is referred to.

Title: Methods of preparing hydroxystilbene derivatives
IPC: C07C37/055
Filed: 1943-02-17
Abstract: Hydroxystilbene derivatives of the general formula <FORM:0584253/IV/1> are prepared by allowing a ketone of the general formula <FORM:0584253/IV/2> to react with a Grignard reagent of the general formula <FORM:0584253/IV/3> to produce an intermediate compound of the formula <FORM:0584253/IV/4> which is then decomposed in one of two alternative ways: (1) by treatment with dilute acids, dehydration and dealkylation.  (2) Decomposition by heat and dealkylation.  The initial condensation is preferably carried out in an oxygen-free atmosphere and a dry solvent such as an ether, and also preferably in the presence of a catalyst.  Specified catalysts are halogens, tertiary amines, carbon disulphide, heavy metal halides such as manganese dichloride, chromium trichloride, ferric trichloride, cobaltic tribromide, and magnesium iodide, organic halides such as methyl iodide or other halogen mono-, bi-, tri- or higher substitution products.  The Grignard reagent may be produced separately and then reacted with the ketone or it may be produced in the presence of the ketone, in which case it reacts as it is formed. The final dealkylation process is preferably carried out by treatment with an alkali metal hydroxide in a polyhydric alcohol.  In examples: (1) Magnesium turnings are added to an ether solution of the compound CH3O.C6H4.CHCl.C2H5 and the resulting Grignard reagent separated and added to an ether solution of the ketone CH3O.C6H4.CO.C2H5.  The reaction product is decomposed with dilute acid and dealkylated.  (2) The compound CH3O.C6H4.CHCl.C2H5 is converted into the Grignard compound as in example (1) and added to a benzene solution of CH3O.C6H4.CO.C2H5 and the resulting Grignard reagent separated and decomposed by heat and then dealkylated.  The Specification as open to inspection under Sect. 91 includes also the subject-matter of Specification 584,705.  This subject-matter does not appear in the Specification as accepted.

Title: Method of treating synthetic fibres with organosiloxane compositions and the treated fibres obtained therefrom
IPC: D06M101/16
Filed: 1978-01-24
Abstract: To the surface of the substrates is applied a polysiloxane which has triorganosiloxane end groups and which on average contains at least two nitrogen-containing siloxane units carrying a radical of the formula            -R'(NHCH2CH2)aNHR''  where     a is 0 or 1, R' is a bivalent hydrocarbon radical that is alkyl, cycloalkyl, aryl or aralkyl, and R'' is hydrogen or a univalent hydrocarbon radical that is alkyl, cycloalkyl, aryl or aralkyl.   The amine functionality of the polydiorganosiloxane expressed as weight percentages of NH or NH2 groups, based on the total weight, must be less than 4 % and the remaining organic radicals of the polydiorganosiloxane must be univalent, optionally fluorinated alkyl or aryl hydrocarbon radicals. The polysiloxane is applied in the form of a liquid and cured by heating, advantageously without a curing agent. It improves the properties of these substrates, in particular the handle, without adversely affecting the flammability characteristics to any significant extent.

Title: Improvements in or relating to ordnance
IPC: F41A21/12
Filed: 1945-02-06
Abstract: 600,740. Ordnance. BURNEY, SIR C. D. Feb. 6, 1945, No. 2960. [Classes 92 (i) and 92 (ii)] The cartridge chamber 2 of a gun is of greater diameter than the bore of the barrel 1 and is eccentrically disposed in relation thereto. In the construction shown, the axis of the chamber is displaced from the axis of the bore in an upward direction, the enlarged chamber thus not causing any obstruction liable to reduce the maximum degree of elevation of the gun. The enlarged chamber gives a pressure-space curve of high mean value and low maximum pressure, with the result that the bore of the barrel may be lower than usual and the length of the barrel increased. To counterbalance the weight of the barrel, a lead-filled weight 5 is mounted on the chamber 2. Specification 592,092 is referred to.

Filed: 1970-01-21
Abstract: 1284061 Photo-electric apparatus CAMBRIDGE SCIENTIFIC INSTRUMENTS Ltd 19 April 1971 2829/70 and 32059/70 Heading G1A [Also in Division H1] In a scanning electron or ion beam micro-scope or micro-probe, the point of impact of the beam on the specimen remains substantially constant but the angle is varied periodically in order to observe a pseudo-Kikuchi effect in single crystal specimens. In Fig.4 one or more focusing coils L2 converge the beam at a point I on the axis where the beam is subjected to scanning fields from orthogonal scanning coils D1. The final focusing lens L3 converges all electrons at a point on the specimen, so the effect of the scanning is to vary the angle of incidence of the beam in two orthogonal planes. The point of impact may vary due to spherical aberration of the lens L3 and this may be corrected by moving the centre of deflection in accordance with the magnitude of the deflection by means of auxiliary deflection coils D2 and E. Alternatively the accelerating voltage may be varied, or the current through the lens L3 may be varied and this may be facilitated by using an air-cored coil for the lens L3 or for an auxiliary correcting lens. If the lens L3 is iron cored, the need for rapid changes in the current through it may be obviated by using spiral scanning Fig. 5 (not shown), the coils D1 being fed with sine and cosine waveforms. The output signal may be derived from backscattered electrons or from the specimen current, and is fed to a cathode ray display tube scanned in synchronism. Alternatively the output may be light or X-rays generated by the impingement of the beam.
