   nach welchem das Bogen@tück a gestaltet ist, berühren, so schliessen sie, mathematisch gesprochen,   den Abstand Null ein, welcher bei der vorgestellten Aufüahmehöhe Unendlich der Masseinheit entspricht. Damit ist also der   Nullpunl < t für die die Aufnahmehöhen ausdiückenden sinoidalen  
Skalen auf den Zirkelschenkeln gegeben. Die Skalen gelten natürlich nur für eine gewisse auf dem Bild abzugreifende Masseinheit, z.

   B. 100 m, doch lässt sich auf den Zirkelschenkeln natürlich noch je eine zweite'Skala tür eine andere Masseinheit anbringen. 
 EMI2.1 
   insbesondere für   Zwecke des Heeres und der Landesaufnahme in Betracht kommen, so kann das Instrument natürlich auch für vertikal transformierte Aufnahmen, die als Architekturaufnahmen und Aufnahmen für geographische und geologische Zwecke eine Rolle spielen können,   benutzt Werden   ; aus dem Faktor Aufnahmehöhe wird hier natürlich der aktor Entfernung.

   according to which the sheet @ piece a is designed touch, so they include, mathematically speaking, the distance zero, which corresponds to infinity of the unit of measurement at the presented Aufüahmehöhe. This means that the zero point for the sinoidal heights expressing the reception heights is
Scales given on the legs of the compass. The scales are of course only valid for a certain unit of measurement to be taken from the picture, e.g.

   B. 100 m, but of course a second scale for a different unit of measurement can be attached to each of the compass legs.
 EMI2.1
   come into consideration especially for purposes of the army and land survey, the instrument can of course also be used for vertically transformed recordings, which can play a role as architectural recordings and recordings for geographical and geological purposes; The actuator distance is of course derived from the factor of the mounting height.

PATENT-ANSPRUCH aspre Zirkel zum Abgreifen von Entfernungen auf transformierten Geländeaufnahmen (und Karten), dadurch gekennzeichnet, dass die Zirkelschenkel in Gerndführungen, welche vermöge eines Gradbogens gegeneinander einstellbar gind, radial verschiebbar und nach die Aufnahmehöhe ausdrückenden Sinusteilungen einstellbar sind. PATENT CLAIM aspre Compasses for measuring distances on transformed terrain surveys (and maps), characterized in that the compass legs are radially displaceable and adjustable according to sinus divisions expressing the recording height in Gerndführung, which can be adjusted against each other by means of a straight line.
