Abstract: The invention relates to a shaft furnace (1), in particular a direct-reduction shaft furnace, having a bed (2) of lumpy material, in particular lumpy material containing iron oxide and/or iron sponge, having worm conveyors (3) which penetrate through the shell of the shaft furnace for discharging the lumpy material from the shaft furnace (1), which conveyors are arranged above the base area of the shaft furnace (1) and are mounted in the shell of the shaft furnace.

Abstract: A circular loom for the manufacture of tubular fabrics having an annular frame with an upper annular plate and a lower annular plate, both having bearing bores for vertically moving healds (heddles) guiding the warp threads of the hose to be manufactured. Said healds are arranged on the periphery of said frame and are mounted on at least one continuous circular path such that they may be individually vertically displaced. For this purpose, the lower ends of the healds arranged in each circular path have cam following rollers running on a rotary driven cam-like control ring. More than one set of healds (with corresponding rotary driven control rings) along additional circular paths may be used.
