Title: Self-sealing coke oven doors
IPC: C10B25/16
Filed: 1946-06-29
Abstract: 612,076. Doors for resisting fluid pressure. SEMET-SOLVAY CO. June 29, 1946, No. 19519. Convention date, Sept. 12, 1945. [Class 123(i)] A self-seating closure, especially for an opening in a coking chamber, which provides for ready replacement of the sealing edge without dismantling the remainder of the door closure parts, has a grooved holder which surrounds the opening, a flexible replaceable sealing blade being frictionally held in the groove and being readily removable therefrom, the blade having a sealing edge extending beyond the holder. In the coking chamber closure shown in Fig. 1, the door is provided with a diaphragm plate 22 having a grooved holder bar 28 welded or otherwise secured along its marginal edge so as to surround the opening to the coking chamber 10. The holder bar 28 is made in two similar parts, 31 and 32, which are positioned on the plate so that the grooves therein are mutually displaced a lateral distance equal to the width of the groove, whilst the sealing blade is also made in two U-shaped portions 37 and 39, the portion 37 fitting into the upper groove and the portion 39 into the lower, the blades being held in the grooves by direct frictional engagement with the sides thereof, and slidably engaging and overlapping at their ends as shown in Fig. 4, thus allowing for expansion of the blades whilst maintaining the continuity of the sealing edge. To prevent expansion buckling the blades, they are made slightly shorter than their respective grooves, allowing an expansion space 38. Bolts 27 are provided at points around the periphery of the plate 22 so that the sealing edge can be pressed into engagement with the door frame 13, thus providing a substantially gas-tight closure. Specification 470,684 is referred to.

Abstract: 600,951. Rotary compressors. WALTERS, C. R., and CARTER, A. C. July 31, 1945, No. 19636. [Class 110 (ii)] [Also in Group XIII] A rotary compressor 15 for a refrigerating machine and a lubricant separating space C are both located in a casting 6 and separated by a wall or partition 33 transverse to the rotor shaft, the lubricant, e.g. glycerine, which is denser than the liquid refrigerant, being returned by passages 27, 28 in the casting 6 and a bearing plate 7 to the compressor bearings 29, 30 and also by axial passages 31 in the stator sections 9, 10, 11 to the bearing 32 at the other end of the rotor. The lubricant also passes between the end sections 9, 10 and the rotor to the suction inlet of the compressor. Gaseous refrigerant from the evaporator F enters the compressor by a pipe G and passages 20, and the refrigerant under pressure, together with lubricant, is delivered into a space 22 from which it passes through a pipe 23 to the condenser which is formed by the annular space between the casting 6 and an outer finned cylindrical barrel A. To cool the condenser and compressor, a fan 14 on the compressor shaft blows air through the inside of the condenser and around the casting 6 and lubricant separating space C. The liquified refrigerant and the lubricant pass by a pipe 24 to the space C whence the refrigerant is led to the evaporator by a pipe H. Specification 600,952, [Group XIII], is referred to.

Abstract: 891,731. Mixing solids and liquids. IMPACT MIXING CORPORATION. June 20, 1958 [June 4, 1957], No. 19915/58. Class 86. [Also in Group XII] Finely divided solids are mixed with a bituminous or other thermoplastic binder, e.g. in the manufacture of briquettes, the hot binding agent under pressure being first mixed with superheated water and then sprayed over the solid particles. Fine coal, after being dried and heated to about 200-205‹F., is fed into a chamber 1 in which blades 3 mounted on horizontal parallel shafts 2 rotated in opposing senses whirl the coal into a zone 4 of floating particles. Atomising nozzles 5 mix liquid pitch fed through a pipe 6 with superheated water fed through a conduit 7 provided with a check valve 8 and a cut-off valve 9. The pitch and water are mixed in equal proportions, the pitch being at a temperature of about 350‹F. and a pressure of 285 1b/in<SP>2</SP> and the water at the same temperature and a pressure of about 300 1b/in<SP>2</SP>. The mixture of water and pitch is sprayed through the nozzles in such a quantity that the briquette mix before pressing contains about 4% pitch and 4% water. The finished mix is discharged by opening a rotary gate 10 and during mixing the aggregate is kept at an elevated temperature by means of a heating jacket 11. The process may be used for briquetting metal ores or flooring materials. Specification 634,590 is referred to.

Abstract: 680,171. Distilling solid carbonaceous materials. STANDARD OIL DEVELOPMENT CO. Aug. 16, 1950 [Nov. 1, 1949], No. 20344/50. Class 55 (i). In a fluidized carbonization process wherein the fluidizing gases are free from constituents reacting exothermically with the materials being carbonized, the materials to be carbonized are preheated to a temperature of at least 400‹F., but substantially below the temperature of carbonization and the temperature of carbonization is maintained exclusively by the preheating and heat evolved during the process of carbonization. Particulate solids, such as finely divided coal, are fed from a hopper 1 to a preheater 2 and preheated to a temperature of between 400-800‹F. before passing to a carbonization zone 10 through line 4, fluidizing gases being supplied to the zone through a line 6. In starting up the process oxygen and hot gases may be supplied through a line 16 until the necessary temperature is obtained. Hot distillation residue from the zone 10 is circulated via line 46 through the preheater 2 and a proportion may be added to the preheated charge through line 42, any surplus residue being withdrawn through line 43. In a modification the solids feed is also preheated by indirect heat exchange with the hot gaseous distillation products. Carbonization temperatures of 800‹-1,200‹F. and pressures up to 500 lbs. per sq. inch are employed. The temperature in the carbonization zone may be controlled by the provision of a cooling coil therein. The time of residence of the solids in the carbonization zone is such that it is about five times the minimum coking time of the particular charge, so that at least 80 per cent of the charge will be held in the carbonization zone for a longer time than the minimum coking time.
