"AutokL-v for accelerated setting of on the basis of Cement manufactured objects, especially asbestos · ment plates by heating (with steam) "

This liriinäung relates to an autoclave for the accelerated setting of cement produced on the basis of objects, insbecondere Asbestzementpli _tten-t by Jirwärmen (with steam).

La is already such an autoclave for carrying out Treatments known, in which it is expedient or indispensable for accelerated setting of the objects to facilitate the free circulation of a liquid and the transfer of heat between the objects.

After the treatment in the autoclave, the carriages are withdrawn and the support tables are opened tilted again to bring the stacks of panels back into their horizontal position. Now there is an autoclave several ■; * agen, with a length of 50 m for example 16 to 25 cars may contain, each of which supports a support table and a stack of plates, requires tilting the stacks of plates outside of the autoclave and before loading as well as after emptying the trolleys from your autoclave a large number of consecutive operations.

Furthermore, because of the special shape of the support tables, which carry the plates., and their space requirements, necessary to use an atoclave, the diameter of which is larger. '
