   Die beiden Solenoide 4 und 6 sind mit einem gemeinsamen Kern 9 versehen, mit welchem der hebelartige Griff 10 des Lufthahnes 11 durch Stift und Schlitz verkuppelt ist. 



   Bei normalem Vacuum des Kochers steht das Quecksilber im Manometer ausser Berührung mit den Drähten 5 und 7, der Kern 9 hat die Endlage, in welche ihn das Solenoid 6 zieht, und der   Lufthahn H   ist geschlossen. Wird nun das Vaeuum im Kocher gesteigert, so steigt das Quecksilber in der Röhre 1 und schliesst durch seine Berührung mit dem Draht 5 den Stromkreis der Batterie 3 über das Solenoid 4,   3,   4, 5, Quecksilber 8, 3. Das Solenoid 4 zieht den Kern herein und öffnet dadurch den   Lufthahn   11. 



  Indem nun das Vacuum im Kocher wieder sinkt, und zwar unter den normalen Betrag, fällt Quecksilber aus Rohr 1 nach Gefäss   2,   bis Draht   5   entblösst, dagegen Draht 7 bedeckt wird, und es stellt sich unter Öffnung des Stromkreises über Solenoid 4 der Strom-

 steigt wieder auf den normalen Betrag, so dass durch   das Aufsteigen des Quecksilbers in 1   der Draht 7 wieder entblösst, d. h. der Stromkreis des Solenoides 6 wieder geöffnet, der Draht 1 dagegen nicht bedeckt wird. Der Lufthahn verbleibt in der   Schlussiage   bis zur folgenden   Steigerung dAS Vacuums.

   The two solenoids 4 and 6 are provided with a common core 9, with which the lever-like handle 10 of the air tap 11 is coupled by a pin and slot.



   With normal vacuum of the cooker, the mercury in the manometer is out of contact with the wires 5 and 7, the core 9 has the end position into which the solenoid 6 pulls it, and the air cock H is closed. If the volume in the cooker is increased, the mercury in the tube 1 rises and, when it touches the wire 5, it closes the circuit of the battery 3 via the solenoid 4, 3, 4, 5, mercury 8, 3. The solenoid 4 pulls the core in and thereby opens the air valve 11.



  As the vacuum in the cooker sinks again, below the normal amount, mercury falls from tube 1 to vessel 2 until wire 5 is exposed, whereas wire 7 is covered, and the electric circuit is opened via solenoid 4.
 EMI2.1
 rises again to the normal amount, so that the wire 7 becomes exposed again due to the rise of the mercury in FIG. H. the circuit of the solenoid 6 is opened again, the wire 1, however, is not covered. The air cock remains in the closing position until the following increase in the vacuum.

PATENT-ANSPRUCH : Ausführungsform des durch das Stammpatent Nr. aó1 geschützten Apparates zur Abdampfung von Lösungen fester Substanzen, dadurch gekennzeichnet, dass die periodische Öffnung des Lufthahnes sich auf elektrischem Wege in der Weise vollzieht, dass durch die periodische Erhöhung des Vacuums ein mit dem Vacuumraun'. des Kochen communicierendes Vacuummeter, am einfachsten ein Quecksilber-Manometer (1, 2) zunächst einen den Lufthahn öffnenden elektrischen Stromkreis schliesst, während bei hierauf folgender Erniedrigung des Vacuums das Quecksilber-Manometer (1, 2) einen Stromkreis herstellt. der den Lufthahn schliesst. PATENT CLAIM: Embodiment of the apparatus for the evaporation of solutions of solid substances protected by the parent patent no. Aó1, characterized in that the periodic opening of the air cock takes place electrically in such a way that the periodic increase in the vacuum causes a vacuum. of the boiling communicating vacuum meter, the simplest is a mercury manometer (1, 2) first of all closes an electrical circuit that opens the air cock, while when the vacuum is subsequently lowered, the mercury manometer (1, 2) creates a circuit. which closes the air valve.
