Method of using ultrasound to promote crystallization of solid substances contained in a flowabl |
November 3, 1998 |
| A flowable material, such as a supercooled melt or supersaturated solution, is dispensed onto a take-up member such as a belt or drum. Either prior to, or after being dispensed onto the take-up member, the material is exposed to ultrasound to promote the crystallization of solid substanc |

Method and apparatus for purifying chemical substances |
September 22, 1998 |
| After being subjected to a melt crystallization operation, a crystal-containing melt is formed into particles of the same size and shape and then conducted in counter-flow relationship to washing liquid in a washing column. The crystal-containing melt can be formed into particles by |

Process and apparatus for material separation by crystallization from the melt |
March 10, 1998 |
| Crystallization of a melt is induced by causing the melt to flow downwardly in a gap which is defined by upwardly moving cooled walls so that crystallate adheres to the walls and is carried upwardly for recovery. The walls are formed by endless belts which are cooled by fluid sprayed fro |

Process and device for cleaning the waste air of systems for the solidification of melts |
October 29, 1996 |
| A melt is converted into pieces by being converted to individual quantities that are dropped onto a cooling surface. Disposed above the cooling surface is a hood having a suction outlet for conducting waste air to a cleaner. Disposed in the hood upstream of the suction outlet is an a |

Method and apparatus for purifying the exhaust air of installations for consolidating molten sub |
September 24, 1996 |
| A molten substance is consolidated by being deposited onto a cooling belt which conveys the substance through a space formed between the belt and an overhead hood. The formation of exhaust dust from the substance is minimized by controlling heaters in the hood to vary the temperature alo |

Process for separating and purifying substances by crystallization from the melt |
September 5, 1995 |
| In the process for separating and purifying substances by crystallization from the melt under pressure, the melt is subjected to pressure under an inert gas atmosphere and then cooled, whereupon it crystallizes. The residual melt is separated from the resulting crystals, after which the |
