Description
Barometer, bei welchem die Wetterringscheibe und die Barometerskalenscheibe gegeneinander drehbar sind Die Erfindung betrifft ein Skalenscheibenpaar fier Barometer, welches gestattet, für jeden Ort die Wetteraufschriften in einfachster Weise richtig in bezu.g auf die Barometerskala einzustellen.Barometer, in which the weather ring disc and the barometer dial are mutually rotatable The invention relates to a pair of dials fier barometer, which allows the weather inscriptions to be correct in the simplest possible way for every location in relation to the barometer scale.
Es sind zwar Barometer bekannt, welche eine derartige Einstellung erlauben, jedoch braucht man hierzu die bekannte Tabelle der mittleren Ortsbarometerstände.It is true that barometers are known which have such a setting allow, but you need the well-known table of mean local barometer readings.
Die Erfindung stellt demgegenüber eine wesentliche Vereinfachung und Verbesserung dar, indem die eben erwähnte -Tabelle in besonderer Skalenform, und zwar als Ortshöhenteilung bereits auf der Barometerskalenschebe vorhanden und teilweise durch einen Ausschnitt der darüber befindlichen Wetterringscheibe ersichtlich ist.In contrast, the invention represents a substantial simplification and This is an improvement by adding the above-mentioned table in a special scale form, and although already present and partially on the barometer scale as a local height graduation can be seen through a section of the weather ring above it.
In- der Zeichnung ist ein Ausführungsbeispiel der Erfindung veranschaulicht, und zwar zeigt Abb. i eine Gesamtansicht des neuen Scheibenpaars, während Abb. z den Legendenring und Abb. 3 die Zahlenscheibe je für sich in Ansicht darstellen.In the drawing, an embodiment of the invention is illustrated, namely Fig. i shows an overall view of the new pair of discs, while Fig the legend ring and Fig. 3 each show the number disc separately.
Die neue Skalenscheibe besteht aus der unteren Zahlenscheibe ca und dem darüber wechselseitig verschiebbar angeordneten Wetteranzeigering b, der einen mit einer Einstellmarke d versehenen Ausschnitt oder ein Fenster c aufweist. Die Zahlenscheibe a besitzt neben der bekannten Millimeterteilung e für den Luftdruck noch eine weitere Teilung/, die die Ortshöhe in Meter über dem Meeresspiegel angibt. Beide Teilungen sind derart zueinander angeordnet, daB die bekannten, mittleren Barometerstände der zugehörigen Ortshöhe entsprechen, im gezeichneten Beispiel sind diese Angaben um i8o° gegeneinander verdreht.The new dial consists of the lower number disc approx and the weather indicator ring b, which is arranged to be alternately displaceable above it, the one has a cutout provided with a setting mark d or a window c. the In addition to the well-known millimeter graduation e for the air pressure, the number disc a has Another division /, which indicates the altitude in meters above sea level. Both divisions are arranged in relation to one another in such a way that the known, middle Barometer readings correspond to the associated altitude, in the example shown are this information is rotated by 180 ° against each other.
Soll nun das Barometer in bezug auf seinen Wetteranzeigering b eingestellt werden, so wird dieser oder auch das Barometergehäuse samt Scheibe a so lange verdreht, bis die Höhenzahl des betreffenden Ortes im- Fenster c sichtbar und mit der Einstellmarke d in Übereinstimmung gebracht worden ist (vgl. Abb. i, 5oo m Ortshöhe). Hierdurch erscheint alsdann der mit »Veränderlich« bezeichnete mittlere Barometerstand ohne weiteres über der entsprechenden Druckangabe (in Abb. i, 7i6 mm).The barometer should now be adjusted with respect to its weather indicator ring b are rotated, this or the barometer housing including disk a is rotated as long as until the elevation of the place concerned is visible in window c and with the setting mark d has been brought into agreement (see Fig. i, 500 m altitude). Through this then the mean barometer reading labeled "changeable" appears without further above the corresponding pressure information (in Fig. i, 7i6 mm).
Die Erfindung ist nicht an das gewählte Ausfiihrungsbeispiel gebunden, insbesondere kann die Stellung der Teilungen zueinander, die Lage des Fensters und dessen Herstellung eine andere sein.The invention is not tied to the selected exemplary embodiment, in particular, the position of the divisions to one another, the position of the window and the production of which will be a different one.
