Title: Operation of blast furnace
Inventor: ONO YOTARO
IPC: C21B5/00
Filed: 1986-08-27
Abstract: PURPOSE:To improve productivity with a high oxygen blast furnace operation and to make stable blast furnace operation by blowing a blast gas in a high oxygen concn. range into the blast furnace from the tuyere thereof and blowing a preheating gas into the furnace from a shaft part in the middle of the blast furnace. CONSTITUTION:Ore and coke are loaded into the blast furnace 1 from the furnace top. The blast gas 3 having >=30% and <100% oxygen concn. as well as pulverized coal and steam and furnace top gas 4 as the gas for regulating the tuyere end temp. are blown into the furnace from the tuyere 2. The preheating gas is further blown into the furnace from the middle section thereof to preheat the charge consisting of the ore and coke. Since the blast gas 3 enriched with oxygen is blown into the furnace from the tuyere 2, in this case, the pulverized coal is satisfactorily mixed with the oxygen and the pulverized coal can be completely burned in a receway even if a large amt. of the pulverized coal is blown into the furnace. As a result, the consumption of coke is reduced and the production cost is reduced. On the other hand, the tuyere end temp. rises and the temp. in the upper part of the furnace lowers if the oxygen concn. increases. The furnace top gas 4 heated 6 to about 700-1,300 deg.C is blown into the furnace from the middle thereof after dust removing 5 and the ore reduction is stably executed in order to avoid such temp. decrease in the upper part of the furnace.

Title: Method and device for filling bulk cargo into flexible vessel
Inventor: ORAFU SUTORANDO
IPC: B65B1/06
Filed: 1981-12-16
Abstract: A method and an apparatus for filling bulk material into flexible containers. The filling is carried out through a filling pipe or spout while the container is hanging on a hook. The impervious part of the container, which may be in form of an inner bag, is fastened around the spout and kept in place during the filling operation without any special fastening means. This is obtained by first hanging at least one lifting loop on the hook before the pipe is put into the container. Then the remaining loops are hooked onto the hook during simultaneous or subsequent filling of the container with air. The loops are secured together while the container is hanging on the hook. Thus, the container will be made ready for further transport as soon as it is filled and its impervious bag is closed. The apparatus comprises a batch weigher, storage bin having an outlet into a funnel with a pipe for supplying air. The funnel is connected to a filling pipe which is horizontally movable and placed close to a holding device comprising the hook which is movable both horizontally and vertically.

Filed: 1987-08-14
Abstract: PURPOSE:To effectively dissipate a surplus heat generated from a thermal head through a radiator roller and contrive stabler printing and printing quality, by providing the radiator roller on the opposite side of a platen roller with respect to the thermal head. CONSTITUTION:An ink of an ink sheet 6 is thermally transferred onto a recording paper 5 by a thermal head 3, and a surplus heat generated in this case is transmitted to a platen roller 1. Since the platen roller 1 is rotated and a heat-transmitting part of the platen roller 1 makes contact with a radiator roller 11 formed of a material having high thermal conductivity, however, the heat transmitted to a surface layer of the platen roller 1 is transferred through absorption to the radiator roller 11 before being transmitted to a deep part of the platen roller 1, so that the platen roller 1 is cooled, and the heat is not accumulated in the platen roller 1. As a result, the platen roller 1 is constantly maintained at a normal temperature. On the other hand, the heat transferred to the radiator roller 11 is dissipated from a surface separated from the platen roller 1 as the roller 11 is rotated, and the roller 11 is cooled.
