Abstract

1,257,599. Feeding material to hoppers. HOESCH A.G. 19 Aug., 1970 [25 Sept., 1969], No. 39963/70. Heading B8S. In a gas-lock, Fig. 2, for feeding material from a hopper 4 through a hopper 17, the wear surfaces on the valves 6 and on the seats therefore are readily detachable. As shown in Fig. 1, the seals 14 are retained by rings 15, and mating surfaces 12 are formed on removable rings 11 which have channels 13 for cooling liquid. Fig. 3 (not shown), illustrates an embodiment in which the row cylinder for operating the valve is housed within the valve body 6 and the upper end of the piston-rod is attached to a fixed point.
