Title: Phthalocyanine derivatives
IPC: C09B47/22
Filed: 1948-09-17
Abstract: Acetoacetylamino derivatives of phthalocyanine are made by treating with diketene a phthalocyanine compound containing one or more amino groups attached either to the phthalocyanine nucleus or to one or more aryl radicals which are themselves attached to the phthalocyanine nucleus either by a single linkage or through a bridging atom or group of atoms, e.g. -O-, -CO-, -SO2-, and -S-.  The reaction may be carried out in a diluent, e.g. water, 1-chlornaphthalene, trichlorbenzene, xylene, or o-dichlorbenzene, and the products may be purified by dissolving in caustic alkali and reprecipitation with acid, using to assist solution, if necessary, the condensation product of b -naphthol with ten molecular proportions of ethylene oxide.  The products are themselves colouring matters, but form azo dyes by coupling with diazotized amines in substance or on the fibre.  In examples: (1) diketene is condensed in o-dichlorbenzene with copper, nickel, or cobalt di-, tri-, or tetra-4-amino-phthalocyanine, metal-free tetra-4-aminophthalocyanine, copper or nickel tetra 4-(o- or p-amino-phenylmercapto)-phtholocyanine, copper or nickel tetra-4-(o-or p - amino - phenylsulphonyl) - phthalocyanine, copper or nickel tetra-4-(m-aminobenzoyl) phthalocyanine, copper 3,6-dichloro-41,411,4111 - tri - 4 - (p - aminophenylmercapto)-phthalocyanine, or copper 3,6 : 31,61-tetrachloro - 411,4111 - di - (p - aminophenylmercapto) - phtholocyanine; (2) diketene is ballmilled in water with copper tetra-4-aminophthalocyanine or any of the other bodies listed under (1); (3) the product obtained under (1) from copper tetra-4-aminophthalocyanine is ground with the condensation product of b -naphthol and ethylene oxide, dissolved in caustic soda solution, and treated with diazotized 5 - chloro - 2 - methoxy - aniline, giving a green azo pigment; (4) the same coupling is performed on cotton yarn.  The aminophthalocyanines used as starting materials are made according to Specifications 529,847, 569,200 and 589,118.

Title: Process for the electrolytic production of uranium dioxide crystals
IPC: G21C19/48
Filed: 1963-02-28
Abstract: Uranium dioxide is made by first treating a uranium oxide, e.g UO2 or U3O8 in a fused salt bath, preferably of alkali metal halides, with dry oxygen and HCl gas, at 500-600  DEG C. and then electrolyzing the resulting uranyl chloride in the same bath at the same temperature in an inert atmosphere.  The reaction chamber may be of heat-resisting glass which is not devitrified at the operating temperature. Preferably the salt bath is 41.5 mols per cent of LiCl and 58.5 mols per cent of KCl, or 20 mols per cent NaCl, 30 mols per cent KCl, and 50 mols per cent MgCl2.  Water is removed by passing in dry HCl gas, and after adding powdered UO2, or a fissionable material containing UO2 or U3O8, oxygen is also admitted until deep red colour of UO2Cl2 is formed. Gases are cut-off, an inert gas admitted (HCl gas) and two graphite electrodes operating at 1.5V. are inserted.  After several hours the cathode is removed and washed with tartaric acid solution to remove salts, and the UO2 crystals washed with alcohol/ether and dried. The product is UO2.04 to UO2.01.

Abstract: 1,172,846. Calculating machines. BELL PUNCH CO. Ltd. 8 April, 1968 [22 Feb., 1967], No. 8346/67. Heading G4A. In a calculating machine, destruction of numbers entered into its registers is prevented on detection of inability to carry out a calculation ordered by an instruction key. Each stage of a display register and of a storage register is a decade counting circuit. The display register can be added into the storage register by supplying ten pulses to each stage of the display register in turn until a carry is produced when the remaining pulses of the ten are supplied to the corresponding stage of the storage register. Subtraction is by complemented addition, the pulses being supplied to the storage register until (rather than after) a carry is produced from the display register. Both addition and subtraction are preceded by alignment of decimal points, the decimal point positions in the two registers being specified by extra stages thereof, and if there are more positions to the left of the point in the display register than in the storage register, the calculation is prevented and the register stages receive complete sets of ten pulses so the stored values are not altered. The relative numbers of positions to the left of the point are detected by feeding pulses to the " extra " stages of the registers, each of which on producing a carry sets a respective bi-stable. According to which bi-stable is set first, a third bi-stable is set or not to prevent or allow the calculation respectively. The third bi-stable is also set in multiplication and division operations if the highest order stages of the registers are non-zero. Reference is made to Specifications 1,042,785, 1,172,842, 1,172,844 and 1,172,845 for further details of some aspects.

Abstract: 198,632. Baron, H., (Aldendorff, F.). Feb. 28, 1922. Addition to 188,689. Drawings to Specification. Automatic exchange systems and apparatus; metering.-Relates to 'automatic exchange systems as described in the parent Specification in which a group marking switch first steers the wipers of a uni-motional connector on to a particular group of lines, the wipers being advanced while the group marking switch is receiving numerical impulses, and a line marking switch then causes the wipers to move to a wanted line in this group. According to the present invention, both marking switches are permanently associated with the connector. On the connector wipers engaging a wanted line, the line marking switch is restored, the ringing relay being continuously energized during its restoring moveits arms. The wanted subscriber thus receives a continuous preliminary ringing current which, however, is replaced by the usual intermittent ringing current when the line marking switch arrives at its normal position. Release of the connector is controlled by the group-marking switch which on the calling party hanging up moves to a sub-normal position in which potential is applied to all the group marking contacts of the connector, causing it to move to normal, after which the group marking switch is advanced a further step to its true normal position. The system described is identical with that described in Specification 195,439, in which the above operations are described in detail and in which other features are claimed. Specification 196,990 also is referred to.
