Patent-Ansprüche:Patent Claims: ι . Eine Vorrichtung zum Heben und Senken von Operationssfühlen, bei welcher eine Schraubenspindel d, beim Aufgange des Stuhles an der Drehung gehindert, dem Schaltwerke ο in η als Zahnstange dient, beim Niedergang und gelöster Arretirung in Rotation versetzt und durch den Sperrhaken 0 gebremst wird.ι. A device for raising and lowering operating sensors, in which a screw spindle d, prevented from rotating when the chair opens, serves as a rack for the switching mechanism ο in η , is set in rotation when descending and the locking is released and is braked by the pawl 0. 2. In Verbindung mit der unter 1. angegebenen Vorrichtung die Anwendung eines mit dem Operationsstuhle verbundenen Hülfskolbensr zur Regulirung der Bremswirkung der Schraubenspindel d in der Weise, dafs das von dem Kolben r durch das Rückschlagventil 5 angesaugte OeI beim Niedergange des Stuhles durch eine kleine Oeffnung η herausgeprefst wird.2. In connection with the device specified under 1., the use of an auxiliary piston connected to the operating chair to regulate the braking effect of the screw spindle d in such a way that the oil sucked in by the piston r through the check valve 5 through a small opening when the chair descends η is squeezed out.
