Patent GB-1024486-A (GB)
Title: Naphthalene dyestuffs
IPC: C07D209/80
Filed: 1963-08-27
Abstract: The invention comprises dyes having the general formula <FORM:1024486/C4-C5/1> in which R is a hydrogen atom, or an alkyl, aralkyl, cycloalkyl, or aryl radical, R1, R2 and R3 are lower alkyl radicals, X is an acid radical and the aromatic rings as well as the radicals R, R1, R2, R3 may contain non-ionic substituents. The dyes are obtained by reacting compounds of formula <FORM:1024486/C4-C5/2> with indole derivatives of general formula <FORM:1024486/C4-C5/3> in which the symbols have the meanings as above.  The reactants are heated in an inert liquid generally at 20-150 DEG  C. in presence of an agent causing loss of water from the reactants. The inert liquids include benzene, toluene chloroform, carbon tetrachloride, ethylene chloride, chlorobenzene, dichlorobenzene, dioxane or nitrobenzene, and water removing agents are phosphorus oxychloride, tri- and penta-chloride, thionyl and sulphuryl chlorides and phosgene or mixtures thereof.  Friedel Crafts catalysts, e.g. aluminium, zinc, ferric and stannic chlorides or boron triflouride may also be used in the process.  Specified non-ionic radicals include fluorine, chlorine, bromine, nitro, amino and acyl radicals, lower alkyl and alkoxy radicals, nitrile groups and non-ionic derivatives of carboxylic acids.  In the case when R is hydrogen the dyestuffs obtained as salts can be converted to the corresponding bases which are subsequently quaternized with a compound R1X in which R1 is alkyl, aralkyl or cycloalkyl radical, and X is as above.

IPC: C07C51/31
Filed: 1954-11-23
Abstract: Polyesters, polyamides and polyesteramides are prepared by polycondensing o-carboxy-hydrocinnamic acid of the formula: <FORM:0778311/IV(a)/1> with diols, triols, diamines or aminoalcohols.ALSO:o-Carboxyhydrocinnamic acid is prepared by oxidizing a -tetralone in the liquid phase with nitric acid of density less than 1.4 gms/cc. at temperatures between 75 DEG  and 125 DEG  C., and isolating o-carboxyhydrocinnamic acid from the oxidation products obtained.  Phthalic acid is also formed.  The process may be conducted in a continuous manner.  Oxidation catalysts may be present and those specified are the nitrates of silver, lead, bismuth, iron, nickel, cobalt, manganese, chromium, vanadium, molybdenum and copper, and ammonium vanadate, ammonium molybdate, manganese dioxide, mercuric chloride and potassium chromate. Instead of pure a -tetralone, a crude oxidation product containing a -tetralone and obtained by the oxidation of tetrahydronaphthalene according to the process of Specification 770,478 may be oxidized.  The o-carboxyhydrocinnamic acid may be isolated by cooling the reaction mixture, separating the crystalline material, washing with benzene, dissolving in sodium carbonate solution, treating the solution with charcoal, adding mineral acid and selectively dissolving out the phthalic acid from the precipitated product so obtained as the sodium acid salt with the calculated quantity of sodium carbonate solution. Examples are given.

Title: Improvements in or relating to gyroscopic compasses
IPC: G01C19/38
Filed: 1927-12-17
Abstract: 303,265. Brown, S. G. Dec. 17, 1927. Gyroscopic compasses.-A compass, particularly of the " static " type in which the gyroscope is not subjected to the earth's control, is provided with means to counteract the effect of the apparent variation in the speed of the earth's rotary motion due to the easterly or westerly component of the speed of the ship &c. Compasses of the above type are provided with a weight acting on the axis of the gyroscope to cause precession in azimuth to counteract the effect of the earth's rotation, and in accordance with the invention the action of the weight is varied with variations in course and speed. In Fig. 1 the knife edge bearing 3 supporting the gyro-casing 1 in the vertical ring 2 carries a bracket 4 supporting a spindle 5 to which is attached a rod 8 carrying the weight 9. Also attached to the spindle. 5 is a permanent magnet 7 embraced by coils 6 carried by the bracket 4. The current through the coils is varied in accordance with the course of the ship by means of a step-by-step motor 17 operated in synchronism with the azimuth movements of the gyroscope and connected to a wheel on which are opposed cranks 16 carrying rods 15 on which are brushes 13, 14 for a potentiometer 11 in circuit with the coils 6. The potentiometer is supplied by a battery &c. 12 and the circuit may include a rheostat 19 adjusted according to the speed of the ship &c. The current may also be adjusted in accordance with the latitude. Variations of current in the coils 6 produce turning movements of the spindle 5 with its attached magnet 7 and weight 9 so that, a twisting action is exerted on the casing 1.

Abstract: 1,119,095. Evaporation of scale-forming liquids; desalination of sea water. BETEILIGUNGS - UND PATENTVERWALTUNGS G.m.b.H. 3 Aug., 1966 [4 Aug., 1965], No. 34820/66. Heading B1B. Liquids, containing scale-forming substances, which are to be submitted to evaporation are first contacted with hot particles of solid material whereby the scale-forming substances are deposited on the solid particles, the treated liquid is then separated from the solid particles and is submitted to evaporation. The solid particles are heated by countercurrent contact with the condensate obtained from the evaporated liquid before they are brought into contact with the liquid to be evaporated. Suitable solid materials are gravel, plastics and metals. The treatment is applicable in the desalination. of sea water by distillation carried out in apparatus comprising liquid/solids contacting column 1, multi-stage flash evaporators 3, a column 2 wherein ithe solid particles to be supplied to column 1 are heated by contact with the condensate from evaporator 3, and a device 15 for removing scale from the solid particles being transferred by lift 5 from the bottom of column 1 to the top of column 2. The deposit of scale may be removed from the solid particles by shaking, abrasion, or pressing. Hot solid particles enter the top of column 1 through bucket-wheel lock 10. Sea water, supplied through line 18 is pumped via nozzles 16 into the lower part of column 1 and rises up the column in countercurrent to the descending solid particles. The water, now free from scale-forming components, is withdrawn from the upper part of column 1 through nozzles 17, and is passed through heaters 20 and 22 and through line 24 into the first stage of evaporator 3. The steam evolved in evaporator 3 is condensed by direct contact with a stream of previouslyformed condensate (i.e. distilled water); and the hot condensate passes from evaporator 3 through line 25 into heater 26, and is then conducted through line 28 and nozzles 29 into the lower part of column 2, where it is cooled 'by the descending solid particles. Some of the condensate in line 28 may be passed through heater 20. Cooled condensate flows out of column 2 through nozzles 33 into line 34, some of it being withdrawn from the system through line 35, and the remainder being recirculated through line 36 to the condensation zone of evaporator 3. Some of the brine withdrawn through line 40 from the last stage of evaporator 3 is recirculated through line 41 to column 1, and the remainder is passed to multi-stage flash evaporator 4.
