Installation TTie base of the rauchine is built of four-inch channel iron and fo-ur-inch eye b^iims; sup-ported < the four corners by large castors, sothat the apparatus may be moved about convenient-ly when not in use. The base is rectangular andis tT:\elve -feet long and three and one-half feetwide. The flanges of the end pieces were cut offso that the v/eb of the end pieces V70uld mcike asnug fit into the side pieces. A four-inch eye-beam is located centrally between the two refrigeraing coil box is supported on fivebrackets which straddle the central und sidebeams. The condenser and generator are supportedby eye-beams connected between the one side andcentral beam of base. The legs of the generator absorber aremade of cast-iron and are fastened by bolts to theeye-beams. The old piping was all taken out and replacedby extra heav;; ammonici pipes and the iirr
