Title: New compositions of calcium carbonate, process for the production of the same compositions and uses of the same compositions
Inventor: YASHI EIZO
IPC: C08K3/26
Filed: 1964-08-11
Abstract: Finely divided compositions of CaCO3 with amorphous silicic acid are prepared by reacting, in aqueous solution, CaCl2, colloidal silica or a water-soluble silicate with gaseous CO2 or ammonium carbonate; the reactants are maintained at a pH of 8 or more by addition of NH4OH. Reaction may take place at 35 DEG  C. and above when the aragonite form of CaCO3 predominates or at <35 DEG  C. when vaterite is formed. X-ray diffractiometry is unable to distinguish individual particles of CaCO3 and silicic acid.  The amount of silicic acid may be 2 to 200% by weight of the CaCO3.  The composition of vaterite type CaCO3 with silicic acid may be used as a reinforcing filler for synthetic rubbers.ALSO:A filler for synthetic rubber comprises a finely divided mixture of CaCo3 and amorphous silicic acid.  It is prepared by reaction in aqueous solution of CaCl2 and colloidal silicic acid or a water-soluble silicate with gaseous Co2 or (NH4)2Co3, the pH being maintained at 8 or more during reaction.  Examples relate to its use in styrene/butadiene rubber, acrylonitrile/butadiene rubber and the stereospicifier rubbers cis-polybutadiene and cis-polyisoprene.

Abstract: 450,132. Fire-extinguishing grenades. HARTMANN, C. W., 10, Vinkelvej, Lyngby, near Copenhagen. Nov. 25, 1935, No. 32656. [Class 47 (ii)] Relates to grenades of the kind comprising an explosive charge located within an extinguishing material held in a casing, and consists in producing the casing from liquid, or semiliquid paper pulp by a moulding operation. As shown in Fig. 1, the casing 10 is formed in two hemi-spherical parts by moulding in a suitably shaped mould, which is formed with uniformly spaced ribs to produce lines of weakness 48 in the finished casing. The ribs form grooves 54 and ridges 56, Fig. 3, in the casing, the ridges being reduced in thickness, as by grinding, to weaken these lines. In a modification, the casing is formed in one piece. The casing is provided at one end with a depression 16, in which is secured a wooden disc 18 which supports a paper tube 24 carrying the explosive cartridge 26. A filling neck 32 at the opposite end of the casing is closed by a metal cover 36 to which a wooden handle 46 is secured. Specification 450,133 is referred to.

Abstract: 891,865. Nuclear reactors. GENERAL ELECTRIC CO. Ltd. Sept. 26, 1960 [Sept. 25, 1959], No. 32704/59. Class 39(4) A moderator core structure of the kind in which the main core is comprised of an assembly of lines of square section prismatic blocks of graphite arranged end to end, some at least of the lines of blocks having holes therethrough which align to form channels for the reception of fuel elements, comprises an arrangement of keyed locating tile members which is adapted so that changes of dimension of the tile members and/or keys produce rotary movement of the tile members in such manner as to maintain relative location of the lines of blocks. Fig. 1 and 2 show a plan and part sectional view of a moderator structure comprising blocks of graphite 1 of one layer spigoted by annular spigots 2 to the blocks 3 of the next layer. Graphite tile members 4 of square section, which are a reasonable fit on spigots 2 and pivot freely about them, are provided with keyways 5 at each corner. I-shaped graphite keys 6 being fitted into the keyways with the locating face of each keyway arranged so that the tiles are on the skew as shown. Thus any growth or shrinkage due to Wignes changes causes the tiles to rotate and their locating action is preserved. The corners of the tiles need not necessarily be in contact initially if it is desired to allow limited movement at certain parts of the core. Specification 837,608 is referred to.

Title: Improvements in or relating to synchronising circuit arrangements
IPC: H03L7/10
Filed: 1958-10-14
Abstract: 875,893. Automatic phase control systems. TELEFUNKEN G.m.b.H. Oct. 14, 1958 [Oct. 15, 1957; Nov. 2, 1957; Feb. 18, 1958; Feb. 20, 1958], No. 32746/58. Class 40(5) In an oscillator synchronizing system using a synchronizing pulse train and a retroactive control loop comprising a phase comparator, the oscillator input to the latter is decreased as synchronism is approached by a second phase comparator controlling a variable gain amplifier of the oscillator input to the first phase comparator. This reduces interference without loss of pull-in range. In Fig. 3 flyback pulses 86 from a television receiver line deflection transformer of width equal to the phase pull-in range of the system are applied to the anode of a coincidence detector valve 85 to whose grid are applied synchronizing pulses from a sync separator ECL 80, the combined output being rectified at 87 and applied to control a variable-Á valve 83 variably amplifying flyback pulses 86 differentiated at 220 p. The output pulse 82 of width equal to the pull-in range of phase error and of increased steepness during out of synchronism due to valve 83 and rectifier 87, is then applied together with sync pulses to a phase discriminator 2 with output controlling through a filter a variable frequency oscillator I with output applied to a sawtooth generator. The pull-in frequency error range may therefore be increased from 50 c/s. say at synchronism to 450 c/s. during out of synchronism, giving increased noise immunity, which is not disturbed during temporary fading of sync pulses, by using a long time constant filter 88 between detector 85 and amplifier 83.
