Abstract: 841,670. Charging shaft furnaces. HUTTENWERK SALZGITTER A.G. Aug. 22, 1958, No. 27070/58. Class 51 (2). In a shaft furnace charging device of the hopper and double bell-type, the upper bell 5 co-operates with a rotary hopper 4, and the lower bell 8 co-operates with an intermediate member 10 comprising a cylindrical section 12 with upper and lower frusto-conical sections 11 and 13, said member 10 and bell 8 being adapted to be so positioned relative to the bottom wall 2 of the hopper as to deposit charge material in the centre or at the periphery of the shaft 15. Fig. 2 shows the member 10 and bell 8 lowered together so that material flows over the conical section 13 and inside apron 16 to the periphery of the shaft. Fig. 4 shows the member 10 lowered so that hopper wall 2 and conical section 11 combine to form the lower hopper wall, material flowing over bell 8 and inside apron 14 to the centre of the shaft. The various movements may be controlled by the apparatus shown in Fig. 5 which comprises fluid cylinders 18 and 19 connected as shown by a cable 23 to a pivoted lever 26 from which a cable 23 is connected to the rod 9 of the bell 8. Cylinder 18 opens and closes the bell 8, and if cylinder 19 is first placed under pressure, followed by cylinder 8, the charging device takes up the position shown in Fig. 4.

A feedhold signal can stop the milling tool 14 at any point on its path and the system does not resume normal operation unless and until the tool is returned to the stopping point after it has been displaced therefrom under manual or other control e.g. to inspect or change the tool. The tool 14 moves along two or more axes and can also be a drafting, welding, cloth cutting, flame cutting or painting machine or a robot. Movement along a path segment is by normal linear or circular iterative techniques Fig. 5 (not shown) using device 34 which may be an analog computer, a hardwired computer or a software programmed digital computer Figs. 6 and 7 (not shown). The operator's panel 38 includes tool jogging and direction controls using a joy-stick 40 described in some detail, Figs. 3 and 4 (not shown).
