Abstract: 144,281. Sutherland, I. May 3, 1919, [Convention date]. Kinematograph apparatus.-The film spool has its hub formed by a series of rollers so that the film, which has its ends joined together, can be unwound from the inner periphery and re-wound on the same hub simultaneously after projection so that the series of pictures may be repeated without interruption. In the construction, Figs. 1 and 2, which are plan and side elevation respectively, the rollers R forming the hub are rotatable individually on pins projecting from the fixed frame 1, while the. hub flanges 4 and 5 are rotatable and move along grooves in the rollers R. The flange 4 is driven by chain and sprocket. The film is drawn from the inner coil on the hub by a sprocket 13 passing between a pair of the rollers R. It then takes a helical twist through the central opening of the flange 5, through the like opening in the stand 1, and over a series of guide-pulleys to the film gate 12. It then returns to be fed on to the exterior periphery of the coil on the rollers R. Alinement of the film is obtained by two co-operating tapered guide-rollers 28 and 29. The apparatus is driven by an electric motor which is cut out if the film breaks. To prevent slackness of the film coil, the coil is pressed by a spring 44 and/or by a heavy roller 47.

Patent GB-562581-A (GB)
Title: Alkali-soluble carboxyethyl cellulose ether
IPC: C08B11/12
Filed: 1942-11-02
Abstract: A water-insoluble, alkali-soluble carboxyethyl cellulose ether is produced by mixing cellulose with a solution containing about 15-40 per cent of a strongly basic, water-soluble hydroxide in an amount at least molecularly proportional to the glucose units of the cellulose, and about 0.2-0.5 molecular proportions of acrylonitrile per glucose unit of the cellulose, and allowing the reaction to proceed within the temperature range of 5-35 DEG  C.  The reaction is continued until the reaction mixture is dispersible in a 5-10 per cent solution of a strongly basic hydroxide to form a substantially homogeneous solution or paste.  The cellulosic material may be cotton, regenerated cellulose, cellulose bast fibre, or wood pulp from which resin, lignin, and other impurities have been removed.  The alkali may be caustic soda or potash or a strongly basic quaternary ammonium hydroxide, e.g. benzyl trimethyl or dibenzyl dimethyl or fetraethyl ammonium hydroxide. In an example, wood pulp is treated with a solution of 30 per cent caustic soda in a mechanical mixer. Acrylo-nitrile is added and mixing is continued for several hours. The product is dissolved in 5 per cent caustic soda solution.  The cellulose ether is precipitated by adding acid.  It is washed and then redissolved in p  caustic soda solution.  The cellulose ether may be dissolved in a solution of trimethyl benzyl ammonium hydroxide and sodium hydroxide and used to impregnate a piece of cotton sheeting which is then squeezed, acidified with a solution of sulphuric acid and sodium sulphate, rinsed and dried.  The cloth is stiffened and the effect is retained after laundering with soap and soda solutions. The cellulose ethers obtained by the process may be used as thickening agents, protective colloids, sizing and finishing agents for textiles, and their solutions may be extruded to form filaments and films, coagulation being effected in acid media.

Title: Improvements in or relating to nuclear reactor charging methods
IPC: G21C1/00
Filed: 1959-05-06
Abstract: 923,633. Reactors. SIEMENS-SHUCKERTWERKE A.G. May 6, 1959 [May 6, 1958], No. 15576/59. Class 39 (4). A method of charging a reactor having a fuel lattice disposed symmetrically about an axis and having in each lattice position an equal number of fuel elements disposed one above another in banks, comprises dividing the lattice into coaxial zones equal in number to the number of banks and of differing mean burn-up and transposing the fuel elements from zone to zone in such a manner that at each transposition a fuel element is transposed both into a zone and into a bank which it has not previously occupied. Preferably, the following relationship is satisfied tα:t# . . . t n  = <SP>1</SP>/ 1 α: <SP>1</SP>/ 1 # . . . <SP>1</SP>/ 1 n = Fα:F# . . . F n  where n = the number of fuel rods disposed one above the other in each fuel channel in the lattice and n also equals the number of lattice zones α, # &c., tα to t n  represent the burning times of the fuel rods in the various zones, 1α to In represent the neutron flux densities in the various zones, and Fα to F n  represent the crosssections of the various zones. As shown in Fig. 7 the lattice is divided into four zones α, #, γ, # and each channel contains four fuel rods and thus there are four banks. The fuel rod channels are divided into nine groups A . . . I, each group in zone α having six channels, each group in zone # seven channels, each group in zone γ ten channels and each group in zone 8 sixteen channels. Every eighteen days one of the sixteen channels of a group (i.e. the channel containing the oldest rods) is cleared in the # zone and at the same time the channel is refilled by rods taken from the oldest channel of the same group in the zone γ. Similarly the channel in zone γ is re-filled by rods taken from a channel of the same group in zone # and the channel of zone # is re-filled by rods taken from a channel of the same group in zone α. Finally, fresh fuel rods are inserted in the channel in zone α. The rods are moved from one zone to the next such that each rod occupies a different position in the channel in each of the four zones (Fig. 6, not shown). Since there are nine groups a set of four channels belonging to a group in the respective zones is re-filled every second day, the groups being taken in order, i.e. on the first day group A, in the third day group B . . . eighteenth day a further set of four channels of the group A. Thus each fuel rod has the following burning times in the various zones: tα = 6.18 = 108 days t# = 7.18 = 126 days tγ = 10.18 = 180 days t# = 16.18 = 288 days and the total burning time of each rod is 702 days.
