IPC: C10L5/02
Filed: 1942-05-08
Abstract: <PICT:0581133/III/1> The agglomeration of carbon by agitating it with a bituminous binder as claimed in the parent Specification is modified by carrying out the baking step simultaneously with the agitation. The apparatus comprises an inclined rotary drum 10 with helical baffles 14, having a concentric cylinder 15 in its lower end. Powdered coal &c. is fed to the cylinder by a conveyer 24 and sprayed with tar just below its boiling point from a pipe 27, the ingredients being mixed by a scraper 29.  The resulting nodules are discharged from the upper end of the cylinder into the drum where they roll and slide over the baffles.  Smaller fragments move back to the lower end of the drum where they are picked up by a scoop 18 and returned to the cylinder.  Complete granules are carried to the higher end of the drum which is heated by burners 32 to a temperature of 400 DEG C., and are discharged by the opening 12.  In a modification, the circulation in the cylinder is from the higher to the lower end.  The baffles extend across the annular space between the cylinder and drum, and broken fragments carried up the cylinder by them fall back into the higher end of the cylinder while completed granules are carried on up the drum.

Abstract: 374,115. Microphones. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and OLIVER, D. A., of General Electric Co., Wembley, Middlesex. March 4, 1931, No. 6739. [Class 40 (iv).] Relates to a condenser microphone of the type in which one part of the back electrode is impermeable and the remaining part is permeable to air and consists in forming the part which is permeable to air of conducting gauze. The back electrode may be constituted by a solid annulus, the central opening of which is covered with gauze, or alternatively by a solid disc surrounded by gauze, the solid central portion being preferably considerably smaller than the diaphragm. Such a microphone is stated to have a response curve high at both ends of the audible range but low in the middle. This curve can be improved if a peak is introduced at intermediate frequencies by providing a resonant air chamber immediately in front of the diaphragm by setting the diaphragm back a short distance from the front surface of the microphone according to the desired magnitude of the effect.

Title: An improved process for cracking hydrocarbon oils
IPC: C10G69/04
Filed: 1945-03-20
Abstract: Improved yields of high octane fuel are obtained from crude petroleum oil by subjecting the oil to a primary distillation to separate a gas oil and a heavy bottoms fraction, subjecting the bottoms to (a) viscosity breaking or (b) coking to convert the bottoms mainly to gas oil, hydrogenating the gas oil at elevated pressures and at 600-800 DEG F. in presence of a metal sulphide catalyst to saturate olefinic constituents therein, and catalytically cracking the saturated oil in admixture with the gas oil produced in the primary distillation to obtain gasoline.  The crude stock fed through line 1 is preheated in furnace 2 and passed to tower 10 from which a gas oil fraction is taken overhead through line 12 while heavy bottoms are removed through line 14.  The latter are viscosity cracked or coked in furnace 40 and the products passed to tar separator 45 the tar being rejected through the line 50 while the vapours are fractionated in tower 55 into <PICT:0593496/III/1> gasoline taken overhead through line 60 and light and heavy gas oil fractions removed through line 53, 62.  These fractions with or without part of the gas oil distillate recovered through line 12 and fed through cooler 66 are mixed in lines 67, 70 and fed to the hydrogenation unit 72.  The products from the hydrogenation stage are fed through line 80 and cooler 82 to mix in line 16 with the main gas oil fraction recovered from tower 16 and are subjected together to catalytic cracking in cracking unit 18 the products passing to tower 24 from which the final gasoline product is recovered through line 21 while bottoms are fed with or without separation of catalyst through line 32 to the furnace 40.  A heating oil fraction may be taken off through lines 24, 26 or sent through line 85 to increase the fluidity of the tar bottoms.  Gas oil may be fed through line 30 to the hydrogenation unit or taken off as bottoms.  Operating conditions specified are (a) viscosity unit-temperatures of 850-1200F., pressures up to 200 pounds per square inch times and treatment times 0.5-5 minutes (b) hydrogenation unit-temperatures of 600-800F., pressures up to 1000 lbs. acid feed rates of 2-5 volumes oil per vol. catalyst per hour; hydrogen feed 300-1200 cubic feet with 200 0-15000 cubic feet recycle per gallon oil.
