Title: Manufacture of monobenzoylated 1:4-diaminoanthraquinones
IPC: C09B1/42
Filed: 1949-02-25
Abstract: Monobenzoylated derivatives of 1 : 4 - diaminoanthraquinones are prepared by first oxidizing a leuco-1 : 4-diaminoanthraquinone with a nitrated aromatic hydrocarbon in the presence of a tertiary amine as catalyst to the 1 : 4 - diaminoanthraquinone, which without separation is treated with an approximately equimolecular proportion of a benzoyl chloride or preferably with a slight excess of benzoyl chloride amounting at most to 20 per cent and at a temperature from about 55 DEG  to 70 DEG  C.  The benzoyl chloride may be substituted by halogen, e.g. p-chloro-, alkoxy, cyano, a sulphone group, e.g. methyl, phenyl or benzyl sulphone, or a sulphonamide group, e.g. sulphondimethylamide, sulphondiethylamide, sulphonpiperidide and sulphonmorpholide. The leucoanthraquinone may be used in the stable form with ammonia, and it may be substituted by inert groups.  The preferred oxidizing agent is nitrobenzene, used in presence of a dialkylaniline, e.g. diethylaniline.  The preferred temperature is 160 DEG  C. for the oxidation.  In examples: (1) leuco-1 : 4-diaminoanthraquinone is heated with diethylaniline, nitrobenzene and benzoyl chloride at 60-65 DEG  C. to form 1-amino-4 - benzoylaminoanthraquinone; (2) as in example (1) using slightly different reaction conditions.  If instead of using benzoyl chloride there is used para-chlorobenzoyl chloride there is obtained 1-amino-4-(p-chlorobenzoyl)-aminoanthraquinone. Specifications 270,778, 293,924, [both in Class 2 (iii)], and 571,154 are referred to.

Title: Improvements in or relating to the chlorination of titaniferous materials
Inventor: BENNETT ARTHUR NEVILLE COPNALL
IPC: C22B34/12
Filed: 1955-02-23
Abstract: In the fluidized chlorination of titaniferous material in the presence of a solid or gaseous reducing agent at 850-1000 DEG  C. the temperature is prevented from rising by the addition of an inert solid or liquid material or slurry thereof which volatilizes during said chlorination.  The preferred inert material is liquid titanium tetrachloride: solid ferric chloride and silicon tetrachloride, stannic chloride, slurries of ferric chloride in titanium tetrachloride and liquid nitrogen are also referred to. The chloride if used may consist of a part of the crude condensate from a reaction such as that obtained by chlorinating rutile or ilmenite (which may contain silicon, aluminium, chromium, tantalum, vanadium, niobium, and zirconium) in the presence of 10-30 per cent by weight of carbon based on said titanium material or an equivalent quantity of carbon monoxide. The carbon may have a particle size of 100 to 150 microns and the titanium material may be of large average size.  Oxygen may initially be used to heat the bed by burning excess coke in the mixture.  The coolant may be introduced at e.g. 20-40  DEG  C. above or below the fluidized bed, but preferably is admitted as a stream near the top of the shaft furnace.  In one example, solid ferric chloride is fed from a U-tube in which it is maintained in fluidized condition by means of an inert gas and through a dip pipe on to the surface of the bed.  In a discussion of prior art it is stated that small reactors may be externally heated electrically or that an arc may be used for internal heating: the method of the invention, however, is applied where the size of the reactor is large and heat losses therefore proportionately less. Specifications 724,193 and 762,583 are referred to in the Provisional Specification.

Filed: 1962-02-14
Abstract: 948,550. Centrifugal pumps. H. YOKOTA, and S. YOKOTA. Feb. 14, 1962, No. 5650/62. Heading F1C. A self-priming centrifugal pump comprises an auxiliary volute 4 followed by a diffuser 6 discharging tangentially into the upper part 7 of the main diffuser 5, which forms a continuation of the main volute 3. During normal pumping, the water is discharged through both volutes and diffusers. During priming, water is re-circulated through the main diffuser 5 and main volute 3 to the impeller, where it entrains air from the impeller eye, and thence through the auxiliary volute 4 and auxiliary diffuser 6, entering the upper part 7 of the main diffuser 5 tangentially and whirling along the internal surface of the upper part. The air bubbles in the whirling fluid are urged inwardly by centrifugal force to form a central core of the whirling fluid, this core being held in the upper part 7 by means of a stabilizing member 8 while the relatively bubble-free peripheral part of the whirling fluid returns through the diffuser 5 and volute 3 to the impeller. The upper part 7 may be cylindrical instead of frusto-conical.

Title: Improvements relating to the control of excess air in automatic combustion control systems
IPC: F23N1/02
Filed: 1947-02-27
Abstract: 635,361. Regulating air supply for combustion. IPSCOL, Ltd., LUNNEY, R. H., and WEBB, E. F. D. Feb. 27, 1947, No. 5715. [Class 51 (i)] [Also in Group XXIX] Mechanism for controlling excess air to a furnace equipped with an automatic combustion control regulator and automatic fuel feed control mechanism comprises a differential gear, one element of which is rotated by the feed control and the other by manual control, the third element varying the air flow. When the fuel feed mechanism moves to cater for a given furnace load, a proportional movement is given to a shaft 16 carrying a cam 15, the latter turning a lever 13 which rotates the shaft 11 of the planet wheel assembly of a differential gear 1. Assuming the sun wheel attached to the shaft 5 is locked, rotation of the planet wheels causes the sun wheel attached to the shaft 7 to turn through twice the angle of turning of the lever 13, this causing the drum 8 to alter the tension in the control spring 10 loading a diaphragm subjected to the differential pressure across an orifice in the combustion air duct or between two passes of the boiler, the displacement of the diaphragm operating an amplifier and servo-mechanism coupled to a damper or fanspeed control. If the fuel/air ratio determined by the spring is incorrect, adjustment of the air flow is obtained by manually turning the lever 6 which turns the sun wheel on the shaft 5 and alters the spring tension.
