Patent GB-972204-A (GB)
Title: Steam generating nuclear reactors
Inventor: GREEN ALBERT
IPC: G21C1/20
Filed: 1963-03-07
Abstract: 972, 204. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 18, 1964 [March 7, 1963], No. 9182/63. Drawings to Specification. Heading G6C. In a steam generating nuclear reactor, vertical clusters of fuel rods are cooled by a current of light water which a vertical tube within the cluster carries a flow of light water operating as a moderator. The latter is prevented from boiling by a throttle control of its rate of flow. Each fuel cluster is mounted in a pressure tank located in a colandria tube of a tank containing heavy water moderator. The pressure and colandria tubes are separated by a CO 2  atmosphere. The arrangement produces a radiol distribution of thermal neutron flux which is more uniform and of a higher average value than when the vertical tube within the cluster is replaced by fuel. Each fuel rod is formed of UO 2  pellets contained in a zirconium alloy can. Specification 897,232 is referred to.

IPC: C09D5/46
Filed: 1948-04-02
Abstract: Free-flowing pulverulent plasticized vinyl chloride polymer or copolymer compositions are made by mixing the finely-divided polymer or copolymer, without solid ingredients save a minor proportion of stabilizer or colouring materials, if desired, with a plasticizer for the polymer, whereby a damp mixture containing discrete particles of polymer is formed and heating and agitating the mixture at a temperature in the range of 200 DEG  to 250 DEG  F. for a period of from 10 to 30 minutes until the polymer or copolymer has completely absorbed the plasticizer.

Patent GB-936662-A (GB)
Title: Improvements in or relating to the production of mineral fibre bodies
IPC: C04B26/28
Filed: 1960-03-17
Abstract: 936,662. Mineral fibre sheets &c. GRUNZWEIG & HARTMANN A.G. March 17, 1960 [March 19, 1959], No. 9369/60. Class 96. Sheets or other bodies, which may be of any desired shape, are produced by adding mineral fibres to an aqueous suspension of substantially undissolved starch, forming the desired body from the said mixture by removing most of its water content, gelatinizing the starch in the residual water contained by the body by exposure to heat in an atmosphere saturated with water vapour, and evaporating the residual water at a higher temperature in an atmosphere not saturated with water vapour. The mixture may also contain a carbamide-aldehyde resin precondensate, a " polyethylene derivative," e.g. polyvinyl acetate, which may be chemically or thermally precipitated on to the fibres before the mixture is dewatered. Fibres of high absorptive capacity, e.g. chrysotile asbestos or cellulose, fillers, pigments or stabilizers may also be present. The gelatinization of the starch may be accelerated by the addition of catalysts, e.g. aluminium acetate. A small amount of starch may be dissolved in the water before the rest of the starch is suspended in it.

Title: Improvements in smoke-tube boilers
IPC: F22B7/12
Filed: 1949-04-07
Abstract: 661,986. Return-tube steam boilers. DANKS & CO. (OLDBURY), Ltd., E., and SMITH, J. March 31, 1950 [April 7, 1949], No. 9515/49. Class 123(ii) In a steam boiler comprising two sideby-side furnace flues 15, 17 each with an associated bank 51, 61 of return smoke tubes 25 disposed mainly or wholly above the level of said flues, the smoke tubes in the rows 51d-51h and 61d-61h adjacent to the vertical planes through the axis of the flues are smallerin diameter than the tubes in the remaining rows so as to secure a closer approximation to equality between the gas velocities through all the said tubes. The invention is also applicable to a boiler with a single furnace flue. Moreover, in the actual construction shown, the tubes in the rows 51i-51k and 61i-61k at the adjacent inner sides of the two banks are smaller than those in the rows 51a, 51b and 61a, 61b at the opposite outer sides. Preferably all the tubes taper convergently from their inlet to outlet ends to afford more even velocities of gas flow therethrough.

Title: Improvements relating to the measurement of high alternating current voltages
IPC: G01R15/14
Filed: 1925-04-14
Abstract: 232,593. Haefely et Cie Akt.-Ges., E. April 16, 1924, [Convention date]. Addition to 221,495. Pressure meters.-In apparatus for measuring the maximum value of the pressure in a hightension alternating-current circuit by measurement of the mean value of the charging-circuit of a condenser as described in the parent Specification, a section c, Fig. 2, of the condenser c is connected to earth through two opposed thermionic valves a, b, in series with one of which is a moving-coil or other measuring instrument e. In the circuit of the two valves a, b, is connected a source of counter electromotive force such as a primary or polarization cell d, to counteract the electromotive force due to the heated cathodes which tends to send a current through the valves in series. In order to correct for the alteration in potential of one condenser plate due to the cell d, a primary battery E, or other source of electromotive force is connected in series with the condenser. In order to utilize both halves of the rectified wave, the measuring-instrument e may be differentially wound, one winding being connected in series with each of the valves a, b. The cathodes of the valves may be heated by alternating current. Fig. 5 shows an arrangement in which a negative booster transformer h is connected between the condenser and rectifier circuit, one winding being connected between the measuring section c of the condenser C and the rectifier circuit, and the other winding being interposed between the other condenser sections c<1> and earth. Alternatively the sections c' may be connected to earth through a resistance giving the same voltage drop as takes place in the measuring circuit. In the arrangement shown in Fig. 7, the thermionic valves are replaced by neon tubes, in which case a battery giving an electromotive force of 100 volts or more is required. This may be divided into two parts s, each connected in series with one tube.

Title: Improvements in the method of fixing in place stator cores of induction motors and other laminated cores
IPC: H02K1/18
Filed: 1921-04-02
Abstract: 181,867. Electric Construction Co., Ltd., and Jones, H. April 2, 1921. Casings and frames; cores.-The stator cores of induction motors and other laminated cores are secured in their casing &c. by putting the core plates together and placing them in the mould in which the casing is to be cast in such a manner that the molten metal runs into contact, at intervals with the outer edge of the plates and forms a permanent clamping-means. In the example illustrated, the core A of an induction motor is made up of slotted laminations a with a stronger plate c at each end. The mould is so shaped that there are cast brackets d and flanges e. As the casting cools and shrinks in a longitudinal direction, the flanges e bear up against the endplates c and firmly hold the laminations together. Concentric slots b are cut in the plates near the periphery, so that as the casting contracts radially inwards, the narrow strips f yield and prevent distortion. The application of the invention to the fixing of armature core plates upon a spider is described in the Provisional Specification.

IPC: G01G23/00
Abstract: 3898. Buckton & Co., J., and Wicksteed, J. H. Feb. 17. Testing physical qualities of materials. - In machines of the steelyard type, the life of the knife-edges is prolonged by protecting them from shock due to jump of the beam on fracture of a specimen. For this purpose, the column B which supports the main knife-edge E is undercut, as shown at J, vertically beneath the knifeedge, and is curved concentrically thereto to allow a transverse bar H, carried in stirrups formed on the beam by plates G<3> bolted thereto, to swing with the beam close to the undercut shoulder. When a specimen is fractured, the jump is prevented by the cross-bar engaging the shoulder. The cross-bar may be attached below the shoulder to the column, and the stirrup plates G<3> curved concentrically to the knife-edge as shown in Fig. 2; or a pair of stops H<1>, H<2>, Fig. 6, may be keyed into the overhanging cheeks of the beam so as to engage channels in the column.
