THE MAUSS HYDRO-EXTRACTOR. A DEMONSTRATION will be given next week of the new con-tinuous running intermittent charging and discharginghydro-extractor, recently patented by Mr. W. Mauss. thismachine consists of a centrifugal separation drum formedby two perforated cones which are held together by a. The New Mauss piston moving a toggle in such a way that whenthe drum is closed the toggle arms are in a straight lineperpendicular to the plane of the drum. The toggle beingin this neutral position the tendency of tjje drum contentsto force the cones apart is effectively resisted. When the liquid contents have been discharged through the perfora-tions of the drum, the drum is lowered, still spinning, inits closed position until it is on a level with a differentreceptacle than that which receives the liquid. Then thehydraulic piston by means of a lever forces the toggle armsoutwards and opens the drum, the two cones continuingto spin when separated, and the solid contents under thehigh centrifugal force are instantly discharged. Thehydraulic piston then reverses its action, closes the drum,and lifts it into its former position to receive the newcharge. Several of these machines are now running andabstracting crystals from the mother liquo
