Abstract: An apparatus for automatically stacking steel shapes, preferably, steel angles, comprises an endless conveyor running obliquely towards the traveling direction, a member provided above the conveyor at a proper distance to form a passage, this member serving to prevent steel shapes from overlapping, a stand-by stop lever for keeping steel shapes stopped at an intermediate part of the conveyor, assorting stop levers disposed so as to project from a part of the passage upstream from the stand-by stop lever, a take-out stop member for stopping the steel shapes being conveyed upon retraction of the stand-by stop lever, a stacking lifter located downstream of the conveyor with a certain distance therebetween, a stacking lever for transferring the steel shapes stopped on the conveyor by the take-out stop member to the stacking lifter, a magnet lever for stacking up-side-down the steel shapes on the lifter as the occasion demands, and a guide plate for stacking positively and in order the steel shapes from the lever

Abstract: A method for the manufacture of an activated carbon by subjecting an acrylonitrile polymer to thermal condensation and activating the resultant condensation product and an activated carbon manufactured by said method. The activated carbon obtained is characterized by containing nitrogen in the molecular structure thereof and by having a high adsorbing capacity for mercaptan.

Abstract: A process for the dry distillation of used rubber in a fluidized bed-forming oven comprises heating used rubber under agitation in the presence of solid particles to temperatures sufficient to make the rubber pulverized and further heating the thus-obtained rubber particles to temperatures sufficient to pyrolyze the rubber particles while forming a fluidized bed thereof and burning a part thereof in the stream of an oxygen-containing fluidizing gas.
