Patent GB-402322-A (GB)
Title: Process and apparatus for manufacturing carbon black
IPC: C09C1/54
Filed: 1933-04-12
Abstract: In the formation of carbon black by the thermal decomposition of a hydrocarbon, the hydrocarbon, preferably in gaseous form, is passed through a sheet of flame and closely adjacent to an incandescent surface.  After leaving the dissociating zone, the reaction products, carbon black and impure hydrogen, are cooled as quickly as possible firstly by the injection of a cooled neutral gas, preferably the impure hydrogen referred to, and secondly by a cooling device, such as a spray cooler, before passage through a separating device for removing the carbon.  When a separator of the fabric <PICT:0402322/III/1> <PICT:0402322/III/2> bag type is used, the reaction gases are cooled to a temperature, e.g. 150 DEG  C., which will not injure the fabric but with a centrifugal separator, the degree of cooling need only be sufficient to prevent the carbon from oxidising when exposed to the atmosphere.  In the form shown in Fig. 1, a natural gas is projected by pipes 6 through a sheet of flame produced by burners 5 tangentially arranged and slightly inclined so as to project the flames on to the upper surface of a thin layer of refractory chequerwork 4 through which the hydrocarbon gas also passes.  To define the limits of the flame, a perforated refractory screen 4a is provided a short distance above the burners 5.  After passing the chequerwork 4, the reaction gases are drawn by a fan 13 through a pipe 8 leading to a cooler 9 and a separator 11, the carbon being delivered by a pipe 21 and the gases passed in whole or in part by pipes 12, 14 through a refrigerator 15 to a pipe 16 having branches 17, 18 which deliver the cooled gases to the space below the chequerwork 4 and to the pipe 8 respectively.  Instead of the cooled reaction gases, other neutral gases may be injected into the pipe 16 by a pipe 24, a valve 25 to the cooler being closed.  In a modified form, Fig. 5, the furnace 1<1> is of tubular form and the burner is of the type adapted to produce a short hollow flame 6<1> the outer part of which will impinge on the surface of the refractory lining 2<1> to produce a highly heated band.  The hydrocarbon gas to be treated is introduced behind the flame by a tubular member 4<1>, the gas tending to pass through the outer part of the flame and close to the highly heated part of the lining.  A spray cooler 9<1> is provided to cool the gases prior to a bag separator 8<1>.  A number of these furnace tubes may be nested in a common casing, the intervening spaces being packed with heat-insulating material. In all forms of apparatus the flame employed is neutral.

Filed: 1955-04-15
Abstract: Organic esters of the high molecular weight formaldehyde polymer described in Specifications 748,836, 753,299, 766,524 and 766,629, which contain free hydroxy groups are made by interacting the polymer with a carboxylic or substituted carboxylic acid or an anhydride thereof, preferably in the presence of a catalyst. Esterification may be effected by dispersing or dissolving the polymer in a diluent or solvent or by the direct action of anhydride vapours on the solid polymers.  The catalyst may be a salt whose cation is an alkali metal and whose anion is the product obtained by removing a hydrogen atom from an acid having a dissociation constant which is less than 1.5X10-4 at 25 DEG  C. and/or a basic catalyst.  The anhydride may be of acids such as acetic, propionic, butyric, caproic, decanoic, stearic, cyclohexanecarboxylic, benzoic, 4-phenyl benzoic or phthalic, or a mixed anhydride such as acetic propionic anhydride. Catalysts mentioned are pyridine, quinoline, methylethyl pyridine, dimethylaniline, N - phenylmorpholine, di - ethylcyclo - hexylamine, dimethylcyclohexylamine, trimethyl and triethylamines, the lithium, sodium, potassium, rubidium or cesium salt of formic, stearic, carbonic, benzoic, acetic or sulphurous acid, or disodium phosphate. The diluent or solvent may be n-heptane, hexane, cyclohexane, toluene, benzene or xylene.  The esterified polymers may be treated with an antioxidant stabilizer such as a phenolic compound, e.g. beta-conidendrol, a secondary or tertiary amine, e.g. di - beta - naphthyl - p - phenylenediamine, hydrazines, ureas, or thioureas. The esterified polymer may be made into films, fibres or filaments.

Abstract: 955,848. Warp let-off motion. APPARATEFABRIK A.G. HUTTWILL. March 28, 1961 [March.29, 1960], No. 11315/60. Heading D1E. The warp from a beam 1 passes round fixed roller 89, then round an auxiliary backrest 63 and a main backrest 61, both carried by levers 54 pivoted on a fixed shaft 49. Movement of the levers 54 under gradual changes in the tension of the warp are transmitted by links 53 to frames 48, also pivoted on the shaft 49, to control the drive of the warp beam as described below. Movement of the backrests under sudden changes in tension during shedding and beat-up are resisted by dashpots acting on the frames 48. In addition, a cam turns a shaft 45 carried by the frames 48 to rock the levers 54 during beat-up, thereby increasing the warp tension, the tendency of this action to displace the frames 48 downwards being resisted by the dashpots. Controlling let-off. A rod 17 reciprocated by the slay acts through a bellcrank lever 15, 19 and a rod 20 to oscillate a lever 27, which acts through a rod 18 to oscillate a shaft 12 coupled by bevel gearing 13 to the input of a one-way clutch 7; the clutch behaves as a ratchet and drives the beam 1 through a worm 6. The end 20a of the rod 20 is guided at a constant radius from a shaft 22 and also slides in a groove in the lever 27; the rod 18 is pivoted directly on the lever 27, which is itself pivoted at 26a on a carriage 26 slidable on fixed rods 25. The carriage has rack teeth 26b meshing with a pinion 31 on the shaft 22, which carries another pinion 73 meshing with teeth 71 in the frame 48. Movement of the frame about its pivot 49 rotates the shaft 22, causing the carriage to move to the right or left and thereby altering the distance between the pivot 26a and the end 20a of the rod 20; the amplitude of oscillation of the lever 27, and hence the increments of rotation of the beam, are thereby varied.

Abstract: 609,208. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. June 15, 1944, No. 11428. Convention date, June 16, 1943. [Classes 38 (iv)] [Also in Group XIII] Temperature.-A space heating system comprising circulating means for the heating medium and means for heating the medium, is controlled by inside and outside thermostats. The inside thermostat operates upon the circulating means until the outside temperature is low, whereupon it operates upon the heating means. As shown applied to a central heating system, the boiler 10 heated by a burner 11, supplies hot water through pipe 13 which heats the air pumped into the room by the circulater 16. The boiler water is kept below boiling point by the temperature-responsive device 18 which operates a switch 20, through bellows 19, controlling the burner motor relay 21. The room thermostat 35 normally controls the circulator 16 through relay 36. When the outside thermostat 41 closes due to a drop in temperature, it energizes relay 40 whereby the circulator is run constantly regardless of the inside thermostat 35. Should the relay 36 now operate, it will energize the burner motor relay 21 independently of switch 20. Steam may then be generated and pipe 14 provide extra heat to the air pumped through the circulator. A modification is described employing threewire control of the burner motor, with back contacts on relays 20, 36 and 40.
