Journal . the use of a new inlet appliance, which consists of ahopper forming part of a castuou box 15. \ shaft pro-vided with projecting arms revolves in the lower part ofthe hopper and causes a gradual descent of the sodiumbicarbonate with which the hopper is filled, and which. closes it hermetically. On the other hand, an endless screwV, constantly forces into a tube T, dry aud hot sodiumcarbonate, but as the screw is terminated a little iu frontof C, there is also fonned at this point a hermeticalplug of sodium carbonate. The two products thereforearrive simultaneouslv and in the required proportions in thehopper box B, where they are intimately mixed together bythe actions of arms P in the hopper box. They then enterthe revolving cylinder by falling through the tube T in aconnecting box K, which unites the cylinder by a suitablejoint. The material advances through the cylinder in avery regular maimer notwithstanding its horizontal order to keep the sides free from hard and non-con-ducting crusts a chain K, formed of heavy and massivelinks, is hung inside the cylinder.
