Description
Betr.: Meine Patentanmeldung P 2354515.5 hier: Zusatzpatentanmeldung zum Hauptpatent P 235415.5 'Erweiterung des Verfahrens und der Vorrichtung zur Bestimmung der Grenzflächenspannung und/oder der Dichte von flüssigen Medien nach der Tropfenabrißmethode' Das Hauptpatent beschreibt ein Verfahren und eine Vorrichtung zur Messung der Grenzflächenspannung und/oder Dichten von Flüssigkeiten bzw. Schmelzen mit Hilfe einer differenzierten Wägung eines Tropfens während seines Wachstums bis einschließlich dessen Ablösung von einem in seinen Abmessungen definierten Körper, z.B. Kapillare. Die spezifisch schwerere Phase wächst an der Kapillare, die in die spezifisch leichtere Phase eintaucht, zu einem Tropfen aus. Die Gravitationskraft bewirkt dann bei genügender Größe des Tropfens den Abriß von der Kapillare.Re: my patent application P 2354515.5 here: additional patent application to the main patent P 235415.5 'Extension of the method and the device for determination the interfacial tension and / or the density of liquid media according to the droplet break-off method ' The main patent describes a method and a device for measuring the interfacial tension and / or sealing liquids or melts with the help of a differentiated Weighing a drop as it grows up to and including its detachment of a body that is defined in terms of its dimensions, e.g. a capillary. The specific heavier phase grows on the capillary that is immersed in the specifically lighter phase, to a drop. The gravitational force then causes the The teardrop of the capillary.
Die Erweiterung des Hauptpatentes besteht in der Einleitung der leichteren in die schwerere Phase und die dadurch erforderliche Richtungsänderung der Tropfenaustrittsöffnung, z.B. Spitze einer Kapillare nach oben.The extension of the main patent consists in the introduction of the lighter one into the heavier phase and the resulting change in direction of the droplet outlet opening, e.g. tip of a capillary upwards.
Hierbei wird die zeitliche Gewichtsveränderung eines Systems (Fig. 1) verfolgt. Dieses System besteht aus einem Gefäß (1), das eine spezifisch schwerere Phase (4) aufnimmt, in die ein in seinen Abmessungen definierter Körper (3), z.B. Kapillare, eintaucht. An dem in die Phase () eingetauchten Ende des Körpers (3) wird aus der spezifisch leichteren Phase (2) mit vorgegebener Geschwindigkeit ein Tropfen erzeugt. Dabei werden die zwei folgenden physikalischen Größen getrennt voneinander sichtbar gemacht (Fig. 2).The change in weight of a system over time (Fig. 1) pursued. This system consists of a vessel (1), which is a specifically heavier one Phase (4) accommodates in which a body (3) defined in its dimensions, e.g. Capillary, immersed. At the end of the body (3) immersed in phase () will one drop from the specifically lighter phase (2) at a given speed generated. The following two physical quantities are separated from each other made visible (Fig. 2).
1. Das Gewicht der verdrängten, spezifisch schwereren Flüssigkeit G11 das sich proportional zum Volumen des wachsenden Tropfens verhält, 2. das Abrißgewicht G2, das direkt proportional zur Grenzflächenspannung ist.1. The weight of the displaced, specifically heavier liquid G11 which is proportional to the volume of the growing drop, 2. the weight of the breakaway G2, which is directly proportional to the interfacial tension.
Die Berechnung der Grenzflächenspannung erfolgt wie im Hauptpatent.The calculation of the interfacial tension is carried out as in the main patent.
