Title: Improvements in or relating to arrangements for controlling electric currents or voltages
IPC: G05F1/32
Filed: 1942-05-22
Abstract: 558,318. Automatic control systems ; automatic regulation ; battery charging. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). May 22, 1942, No. 6999. [Class 38 (iv)] [Also in Group XXXIX] Voltage; current.-In a system for regulating a voltage or current a reactor, which may be a leakage transformer as shown, is variable by two mutually opposed windings having a common energizing source, one being in series with a resistor of the silicon-carbide type, to produce an amplified effect with variation of source voltage and the other in shunt with a similar resistor to be maintained at a constant voltage. As shown windings 13, 18 are of the first kind and windings 14, 19 of the second, a standard resistance 27 being in series with winding and resistor. These windings are all subject to the voltage across a load such as a battery 8 charged from an A.C. supply through the secondary windings 9, 22 of the transformers 1, 2 and a rectifier 3. When the charging current exceeds a certain value the voltage across a rectifier 5 fed from a series transformer 4 supersedes that across the battery in the regulation. The effect of variations in the voltage of the A.C. supply is corrected by windings 11, 16 and 12, 17 arranged similarly to those described above. Additional control is obtained by windings 15, 20 taking the load current. Fig. 2 (not shown) illustrates an arrangement using reactors with windings as described above to control an A.C. load voltage, windings such as 15, 20 being supplied through a series transformer and rectifier.

Filed: 1957-03-04
Abstract: 851,415. Electrolytic cells. FARBWERKE HOECHST AKTIENGESELLSCHAFT VORM. MEISTER, LUCIUS & BRUNING. March 4, 1957 [March 3, 1956]. No. 7147/57. Class 41 [Also in Group XXVI] In electrolytic cells, particularly cells for the electrolysis of alkali metal chlorides, means for facilitating adjustment of the anode necessitated by erosion, while maintaining good electrical contact, comprises means on the cell cover for holding, and allowing longitudinal adjustment of a vertical shaft rigidly attached to the electric lead and secured to the anode, adjustment means for the shaft, and a guide bush for the shaft carrying a compressed packing therefor are mounted in an opening in the cover. As shown, a shaft or shank A secured to a horizontal anode in a brine cell is slidably mounted in a flanged ceramic bush B secured between washers D.E. and carrying a compressed packing ring Q of tapered section, the securing means comprising a flanged ring C bolted to the cell cover F. The packing ring Q is preferably cut obliquely to facilitate replacements, is secured by a ring R held down by a pair of pressure levers such as S, and comprises rubber, or of asbestos reinforced with polytetra fluoroethylene or impregnated with chlorinated paraffin wax which acts as a lubricant. Alternatively water or other liquid may be used as a lubricant. A bridge piece G is secured to the ring C and carries a ring H in two parts pivoted about a bolt I. The ring H embraces a nut L engaging a threaded sleeve M secured to the shank A, the nut being rotatable to move the shank longitudinally by means such as a detachable handwheel P. A flexible lead N is soldered to a lug W in electrical contact with the cover F, or with a conductor bar, through a connector X. The lead N and the sleeve M are secured in bores in the shank A with molten tin, the joint with the lead N being assisted by helical groove O in the bore. When current is supplied other than through the cover F the latter, and the ring C, are insulated as, at Z, Y. The skirt of the bush B extends below the liquid level V in the cell and has ribs at its lower end which guide the shank A; the skirt also prevents escape of chlorine when changing the packing ring Q. Any crystallization within the skirt is stated to hold the shank A against rotation without impeding its longitudinal adjustments. The construction is stated to permit changing of the packing rings D E, Q, and the dismantling of the parts B, C, G, H, I, K and S, without disturbance of the anode and its connecting parts. Instead of the nut L other adjusting means may be used such as a helical slot, lever, eccentric, wedge or rack device. The invention may also be applied to anodes having a number of shanks such as A.

Title: Improvements in the production of cellulose
IPC: D21C9/08
Filed: 1948-03-10
Abstract: Cellulose of high degree of purity suitable for use in the production of cellulose derivatives is obtained by treating cellulosic materials with an aqueous caustic alkali solution of concentration 15-22 per cent (calculated on a weight/volume basis in grammes of alkali per 100 c.c. of solution), at a temperature between 40 DEG  and 60 DEG C.  The process may be applied to the further purification of wood pulp or straw pulp which has already undergone a preliminary purification and which has an alphacellulose content above 85 per cent and a pentosan content below 3.5 per cent.  The further treatment may result in a cellulose having an alphacellulose content of 92-95 per cent and a pentosan content below 1 per cent.  No subsequent bleaching is required.  Preferably, 7-12 parts of alkali solution for each part of cellulose material (air-dry weight) is employed.  The alkali solution may be pre-heated to the required temperature and the treatment of the cellulose may last for 45-90 minutes.  After the treatment, the bulk of the solution may be removed by filtration, and the material may be washed to free it from residual alkali and the impurities contained in the solution.  Hot water may be used for the washing.  The last traces of alkali may be removed by washing with very dilute acid.  If alkali-cellulose is required, the cellulose may just be washed so that substantially all the impurities are removed without necessarily removing all the alkali, or the cellulose may be washed with an alkaline solution. The alkali purification treatment may be applied alone or in association with other purification treatments.  An impure cellulose pulp may be subjected to a chlorine or hypochlorite treatment prior to the alkali treatment or a relatively pure pulp may be given a boil with a very dilute alkali solution, e.g. of 2-3 per cent concentration prior to or after the strong alkali treatment.  The purified cellulose may be used for making viscose, cuprammonium cellulose solutions, cellulose ethers, or cellulose esters, and these may be employed in the production of artificial filaments, films, plastic compositions and moulding powders.  Specifications 427,626, 470,764 and 509,938 are referred to.

Title: Process for the manufacture of vat dyestuffs of the anthraquinone series
IPC: C09B1/43
Filed: 1932-03-14
Abstract: Acylaminoanthraquinones are prepared by condensing one mol. of the halides of the dicarboxylic acids of m- or p-diphenylbenzene (with the exception of such carboxylic acids as are capable of p  forming internal anhydrides) with two mols. of 1-aminoanthraquinone or of a nuclear substitution product thereof. Condensation is preferably effected in the presence of a solvent and an acid-fixing agent, and may follow acid halide formation in a single operation.  The products possess superior fastness properties, and also have an improved affinity for the fibre as compared with those of the parent Specification.  In examples (1) p-diphenylbenzene dicarboxylic acid (2 mols.) is converted to the acid chloride by means of thionyl chloride, and the latter condensed with 1-aminoanthraquinone (1 mol.) to give a fast greenish-yellow dye: (2) by using 1 : 3-diphenylbenzene dicarboxylic acid chloride instead a product dyeing a more greenish-yellow is obtained; 1-aminoanthraquinone may be replaced by substitution products such as 6 - chloro - 1 - aminoanthraquinone, 1 - amino-5-benzoylaminoanthraquinone or 1 - amino - 4 - methoxyanthraquinone to give dyes.  m- and p-Diphenylbenzene dicarboxylic acids are prepared by reacting on m- or p-diphenylbenzenes with acetyl chloride according to the Friedel and Craft's reaction and oxidizing the reaction products with chromic acid in glacial acetic acid; the corresponding halides are obtained from the acids in the customary way.  The Specification as open to inspection under Sect. 91 (3) (a) relates also to the use of substitution products of the dicarboxylic acid halides of m- and p-diphenylbenzene; this subject-matter does not appear in the Specification as accepted.

Title: Operation of catalytic converters
IPC: B01J8/02
Filed: 1936-03-13
Abstract: <PICT:0471931/III/1> <PICT:0471931/III/2> In the use of catalytic converters according to the parent Specification for a cycle of alternate endothermic and exothermic reactions, the fluids in each period of the cycle are admitted at such temperatures that that portion of the converter which is common to the reaction and manifolding zones is maintained at constant temperature.  Fig. 1 shows the application of the invention to the heat treatment of hydrocarbons followed by regeneration of the catalyst with an oxidizing gas.  The hydrocarbons are heated to the reaction temperature or slightly above, e.g. to 750--925 DEG  F., in a heater 16 before admission to the converter.  The air for regeneration supplied at 19, is heated to about 800 DEG  F., in a heater 21, preferably by the combustion of fuel admixed with it through pipe 20. The lower partition 5 of the converter and its supports or stiffening members 14 are thus maintained at constant temperature throughout the cycle.  In a modification, the exothermic reactants receive a preliminary heating by exchange with the exothermic reaction products before passing to the heater 21.  Fig. 3 shows a second modification in which part of the regenerating gas is supplied by pipe 19b<1> to a combustion chamber 21b to which fuel is supplied at 20b.  The combustion products leaving at 24b are mixed with the remaining regenerating gas and passed through a coil 26b in the combustion chamber.
