   Zur Einstellung solcher Verhältnisse wird nach dem vorliegenden Verfahren die Kristallisation unter verschiedenem Luftdruck bzw.   Luftverdünnung   vorgenommen. Da hiedurch der Siedepunkt der Lösung sich verändert, so ist man imstande, nach Wahl des Luftdruckes, der über der Lösung gehalten wird, die gewünschte Temperatur einzustellen und zu erhalten. 



   Die Kristalle, die nach dem vorliegenden Verfahren gewonnen werden sollen, können in bekannter Weise aus der Lösung selbst erzeugt werden, und werden darin wachsen gelassen oder es können Kristalle, Kristallmehl oder Kristallsplitter in die kristallisierende Lösung eingebracht werden. 



   PATENT-ANSPRÜCHE :
1. Verfahren zur Beförderung des Wachstums von Kristallen durch Kristallisation in Bewegung nach dem Stammpatente Nr. 53141, dadurch gekennzeichnet, dass der aus der Lösung entwickelte Dampf kondensiert und das Kondensat durch Messen oder Wägen bestimmt wird, zum Zwecke, das Wachstum der Kristalle regulieren zu können.

   In order to set such conditions, the crystallization is carried out under different air pressures or air dilution according to the present process. Since this changes the boiling point of the solution, it is possible, by choosing the air pressure that is maintained over the solution, to set and maintain the desired temperature.



   The crystals to be obtained by the present process can be produced in a known manner from the solution itself and are allowed to grow therein, or crystals, crystal powder or crystal fragments can be introduced into the crystallizing solution.



   PATENT CLAIMS:
1. A method for promoting the growth of crystals by crystallization in motion according to the parent patent No. 53141, characterized in that the vapor evolved from the solution condenses and the condensate is determined by measuring or weighing, for the purpose of regulating the growth of the crystals can.

Claims (1)

Verfahren zur Beförderung des Wachstums von Kristallen durch Kristallisation in Bewegung nach dem Stammpatent Nr. 53141 und Anspruch 1, dadurch gekennzeichnet, dass in dem in die kristallisierende Flüssigkeit zurückzuführenden Kondensat Nährsubstanz aufgelöst wird. Method for promoting the growth of crystals by crystallization in motion according to the parent patent No. 53141 and claim 1, characterized in that nutrient substance is dissolved in the condensate to be returned to the crystallizing liquid. 3. Verfahren zur Beförderung des Wachstums von Kristallen durch Kristallisation in Bewegung, dadurch gekennzeichnet, dass zunächst unter ganzer oder teilweiser Rück-führung des Kondensats in die kristallisierende Lösung bzw. nach den Verfahren der Ansprüche 1 und 2 das Konzentrationsoptimum des Wachstums der Kristalle festgestellt und dann der Druck über der kristallisierenden Lösung derart geregelt wird, dass bei der dem Konzentrationsoptimum ent- sprechenden Temperatur die zu kristallisierende Flüssigkeit kocht. 3. A method for promoting the growth of crystals by crystallization in motion, characterized in that the optimum concentration of the growth of the crystals is determined and initially with full or partial return of the condensate to the crystallizing solution or according to the method of claims 1 and 2 then the pressure over the crystallizing solution is regulated in such a way that the liquid to be crystallized boils at the temperature corresponding to the optimum concentration.
