Abstract
<PICT:0422427/III/1> In dry-cleaning apparatus comprising a main still receiving the used solvent and a supplementary still receiving residual liquid from the main still, the bottom of the main still is so connected with the top of the supplementary still that the vapour distillate from the supplementary still is condensed and passes back into the bottom of the main still, and when the heating medium is cut off from the supplementary still and the pressure therein falls residual liquid is drawn into it from the main still. In the apparatus shown, used solvent is run from the casing c of the rotated or oscillated basket through a valved pipe o<2> and a gauze strainer to a vessel o in which it is heated by a coil p supplied through a pipe q<1> with water of condensation from the steam heating coil q<3> of the main still q and by a jacket receiving water by a pipe p<3> from the condenser r of the main still. The preheated solvent is forced through a pipe s to the main still q, and the vapour passed by a pipe t to the condenser r and a store tank u. Residue is withdrawn periodically from the still q through a pipe q<2> and a pump w to the supplementary still z in which it is heated by a closed steam coil z<3>, the vaporized solvent passing out and condensing in a pipe z<2> and returning to the still q by the pipe q<2>. When the apparatus is not in use the cooling of the still z condenses vapour therein, and any residue is sucked from the still q through the pipes q<2>, z<2>.
