Title: Photographic development
IPC: G03C7/392
Filed: 1965-03-05
Abstract: 1,106,061. Development of photographic silver halide materials. EASTMAN KODAK CO. March 5, 1965 [March 11, 1964], No. 9395/65. Heading G2C.  In the development of multi-layer gelatinosilver halide photographic material with developer solution, over-development of the outermost emulsion layer is prevented by the presence in that layer of between 1 and 10 grams per mole of silver halide of a benzothiazolium salt of the formula: - in which R is hydrogen, methyl or ethyl, R 1  is hydrogen, aryl or arylenethiazolyl, D completes a monocyclic or multi-cyclic aromatic hydrocarbon nucleus which may be substituted, X is an acid radical and n is an integer between 1 and 26, except that when R 1  is aryl n is not greater than 3. The salts include those of the formula: - where R, D and X are as above and m is from 1 to 26. The process is particularly useful in the high temperature development of multi-layer colour material which may or may not have incorporated colour couplers. The benzothiazolium salt may be incorporated in the outermost emulsion e. g. the blue-sensitive layer in colour materials, prior to coating, or in an overcoat .  layer, or the exposed colour material may be immersed in an aqueous bath containing the benzothiazolium salt prior to development, e. g. a prehardener bath, so that sufficient salt diffuses into the outer emulsion layer. Examples are given including one of a colour material containing benzothiazolium salt in each layer, in amounts decreasing from the outermost layer.

Abstract: 948,996. Automatic control systems. MUIRHEAD & CO. Ltd. Dec. 18,1962 [March 12, 1962], No. 9446/62. Drawings to Specification. Heading G3R. To reduce hunting of a synchronous motor driving a flywheel load, an eddy-current brake is energized in accordance with fluctuations in the motor current, so that the increased current due to the rotor lagging or leading the magnetic field increases the damping due to the eddy-current brake to prevent overshoot as the rotor approaches synchronism. As described Fig. 3 (not shown) a motorcurrent signal from a resistor 5 in series with the stator is applied through a diode 9 to a valve 8 producing pulses which are rectified and smoothed at 12, 13 to produce a signal fluctuating with variations in the motor current. The A.C. component of this signal is applied through a capacitor 14 to a valve 15 energizing the eddy current brake 7.

Title: Improvements relating to the electrolytic recovery of metals
IPC: C25C1/08
Filed: 1928-03-30
Abstract: 314,579. Smith, S. C. March 30, 1928. Nickel, depositing.-In the deposition of nickel from a nickel sulphate solution using insoluble anodes, the electrolyte is maintained at low acidity by conversion of the free acid formed as electrolysis proceeds into ammonium sulphate, e.g. by continuous or intermittent addition of ammonia. An acidity of pH = 3.5 - 6.5 is suitable. Cathodes of aluminium or an aluminium alloy are employed. In an example, a nickel sulphate solution containing 5.0 per cent of nickel is electrolyzed in a lead-lined tank with lead anodes, with a cathode, current density of 17 amps. per sq. ft. at 3 volts. The electrolyte is agitated mechanically and the acidity maintained between P<H> = 4.5 and P<H> = 5.5 by continuous addition of ammonia. The temperature is maintained at 48-50‹ C. to prevent crystallization of nickel ammonium sulphate. When the nickel content has fallen to 1 per cent the current density is reduced to 8.5 amps. per sq. ft. Electrolysis is stopped when the nickel content has fallen to 0.05 per cent. The residual liquor is concentrated and cooled for removal of nickel ammonium sulphate by crystallization and further concentrated for recovery of ammonium sulphate. The residual nickel may alternatively be precipitated by addition of ammonium sulphide, and ammonium sulphate crystallized from the remaining liquor.

Title: Improvements in or relating to a process for the preparation of dialkoxythiophosphoryl chlorides
IPC: C07F9/20
Filed: 1951-04-27
Abstract: Dialkoxythiophosphoryl monochlorides of formula <FORM:0692169/IV (b)/1> wherein R1 and R2 are alkyl groups of 1 to 8 C atoms are made by treating a corresponding monoalkoxythiophosphoryl dichloride with a solution of an alkali metal hydroxide in an alkanol containing 1 to 8 C atoms per molecule.  It is stated that anhydrous conditions are required only when preparing the monoalkoxy thiophosphoryl dichloride from thiophosphoryl chloride and in the process of the invention minor amounts of water may be present.  Preferably an excess of alkanol is used as a reaction medium.  At least a molar proportion, preferably 1.05-1.5 mols, of hydroxide is used per mol. of dichloride.  The preferred temperature range is about -10 DEG  to +25 DEG  C.  The monochlorides are used in the preparation of O,O-dialkyl - O - p - nitrophenyl thiophosphates and for this purpose they need not be isolated, the reaction product being treated with an alkali metal p-nitrophenate whilst dissolved in the excess alkanol.  The monoalkoxythiophosphoryl dichloride may be made by reacting one mol. of thiophosphoryl chloride with approximately one mol. of an alkali metal alcoholate in an anhydrous alcoholic medium, preferably at -10 DEG  to +25 DEG  C., or preferably by reacting one mol. of thiophosphoryl chloride with approximately one mol. of a substantially anhydrous alkanol at -10 DEG  to +25 DEG  C. and removing hydrogen chloride until the reaction is substantially complete and thereafter removing hydrogen chloride at a temperature not exceeding about 50 DEG  C.  In examples, thiophosphoryl chloride is treated with (1) anhydrous ethanol to form ethoxythiophosphoryl dichloride which is treated with ethanolic sodium hydroxide to yield diethoxythiophosphoryl chloride; (2) anhydrous methanol to yield methoxythiophosphoryl dichloride which on treatment with methanolic sodium hydroxide yields dimethoxythiophosphoryl chloride; (3) sodium butylate in anhydrous butanol to yield butoxythiophosphoryl dichloride which on treatment with butanolic sodium hydroxide yields dibutoxythiophosphoryl chloride; (4) anhydrous n-hexanol to yield hexoxy-thiophosphoryl dichloride which on treatment with potassium hydroxide in n-hexanol yields dihexoxythiophosphoryl chloride; (5) sodium 2-ethylhexylate in anhydrous 2-ethylhexanol and the product treated without isolation with sodium hydroxide in 2-ethylhexanol to yield di-2-ethylhexoxythiophosphoryl chloride and in (6) methoxy- or ethoxy-thiophosphoryl dichlorides are respectively treated with ethanolic or methanolic sodium hydroxide to yield methoxyethoxythiophosphoryl chloride.
