Title: Improvements in or relating to an apparatus and process for treating polluted liquid
IPC: B01F3/04
Filed: 1949-08-18
Abstract: 679,635. Treating sewage. INFILCO, Inc. Aug. 18, 1949 [April 2, 1949], No. 21507/49. Class 111 [Also in Group II] In a combined aeration and activated sludge process raw or settled sewage is introduced from a pipe 52 and air or oxygen from a pipe 51 into an aeration chamber 30 formed by a hood 21 in a tank 10 and underneath a rotating vaned disc 43 which causes a cyclic flow having radial outward components at the level of the disc and radial inward components below it, and is instantaneously dispersed through a mixture of sewage and activated sludge in the chamber 30. Unabsorbed gas bubbles initiate an air-lift action assisted if required by an impeller 46 up an inner tube 22, the mixture then flowing over a vertically adjustable weir 35 and down a space 33 between the tube 22 and an outer tube 23. The mixture emerges laterally from the bottom of the tube 23 and from the level clarified sewage rises to a launder 15 while mixed liquor flows down the hood 21 and past supporting brackets 24 to the suction space of the rotor 43. Excess air, and gases, e.g. CO 2 , formed in the process, escape from the top of the inner tube 22. Excess activated sludge formed is allowed to settle in a sludge concentrator 53 and is withdrawn by a pipe 54 to maintain the interface between mixed liquor and clarified sewage at the elevation of the lower end of the tube 23. The weir 35 may be apertured to provide a submerged overflow area which may be varied by adjusting the weir vertically, or it may be both apertured and fixed and an individual vertically-movable gate may be provided for each aperture: such variation is for the purpose of controlling the rate of flow from the inner tube 22 to the outer tube 23. The space between tubes 22 and 23 is of sufficient width to permit any air which is intrained and remains undissolved to rise countercurrently to the downward flow of the liquid. The inlets for air and sewage may be spaced apart; the air however should always be discharged below the plate 44 of the rotor 43. The air may be introduced down the shaft 40 made hollow for that purpose. Baffles 38 are provided to prevent rotational flow in a horizontal plane in the aeration chamber 30. The quantity of mixed liquor passing from the aeration chamber through the tubes 22 and 23 and returning (less the clarified effluent) to the chamber is greater than the quantity of sewage flowing in from the pipe 52 in the same time. In a modification the tank 10 and the tubes 22, 23 are rectangular instead of circular in cross-section, two rotors 43 are provided, the vortices set up by their rotation being tangent.to one another and air and sewage are discharged under each rotor.
Patent GB-737184-A (GB)
Title: Production of polyamides
IPC: C08G69/28
Filed: 1952-08-27
Abstract: Polyamides are prepared by intimately mixing an aqueous solution of a polyamine with a water-immiscible organic solvent solution of a dicarboxylic acid dichloride in the presence of an acid binding agent at temperatures from - 15 DEG  to 50 DEG  C.  If necessary a mono- or polyhydric alcohol may be present as anti-freeze agent.  The process may be discontinuous or continuous, the polymer precipitating as a powder.  The Specification lists a large number of amines, acids, acid binding substances and dispersing agents.  In examples: (1) a solution of 1 mol. of sebacyl chloride in toluene was gradually added, with stirring, to an aqueous solution of 1 mol. of tetramethylene diamine and 1 1/2 mols. of sodium carbonate at 0 DEG C.  A 58.3 per cent yield of polymer of 0.81 intrinsic viscosity was obtained.  (2) To a solution of 1.5 mols. hexamethylene diamine hydrochloride at 0 DEG  C. was added, with stirring, a solution of 1.5 mols. adipyl chloride in toluene and an aqueous solution of N-butyl-N-lauryl-b -amino ethane sulphonic acid sodium salt.  An aqueous solution of 6 3/4 mols. sodium hydroxide was then added, with stirring, over a period of 4 minutes.  A polymer precipitated immediately, in 44.2 per cent yield, having an intrinsic viscosity of 0.24.  (3) An aqueous solution of 46.5 parts per litre of hexamethylene diamine, 64 parts per litre of sodium carbonate and 30 parts per litre of sodium lauryl sulphate solution, and a toluene solution of 37 parts per litre of adipyl chloride were added, the latter solution at twice the rate of the former, to a reaction zone of restricted size.  The contact time in the zone was 2 minutes.  A 37.5 per cent yield of polymer of intrinsic viscosity 1.14 was obtained.  The process of the invention enables polymers to be prepared from short chain intermediates, side reactions, such as 5- or 6-membered ring formation, being avoided.
