Description
Quecksilberbarometer und Barograph. Gegenstand der vorliegenden Erfindung ist ein Quecksilberbarograph, bei dem das Quecksilberbarometer durch keinerlei mechanische oder andere Einrichtungen in seinem Gang gestört wird und bei dem nur die Schwerkraft den Schreibvorgang auslöst. Zu diesem Zweck ist das Quecksilberbarometer in der bereits bei Quecksilberthermometern bekannten Art-in der Weise drehbar gelagert, daß eine Änderung des Quecksilberstandes eine Drehung des Barometerrohres zur Folge hat.Mercury barometer and barograph. Subject of the present invention is a mercury barograph in which the mercury barometer is not operated by any mechanical or other facilities in its course is disturbed and in which only gravity triggers the write process. For this purpose the mercury barometer is in the already known from mercury thermometers - rotatably mounted in this way, that a change in the mercury level results in a rotation of the barometer tube Has.
Die Figur zeigt schematisch den Apparat. Das Barometerrohr B ist hier länger als bei dem gewöhnlichen Barometer, und es ist zur Vertikalen geneigt an einem Waagebalken W starr befestigt, der auf der Schneide S spielt. Der Drehpunkt bei S liegt etwas über dem Schwerpunkt des ganzen Systems.The figure shows schematically the apparatus. The barometer tube B is here longer than the ordinary barometer, and it is inclined to the vertical rigidly attached to a balance beam W, which plays on the cutting edge S. The fulcrum at S is slightly above the center of gravity of the whole system.
Man kann dem Quecksilbergefäß zweckmäßig einen zwiefach symmetrischen Querschnitt geben und die W aagenschneide irgendwo in die Symmetrieebene dieses Gefäßes legen.The mercury vessel can expediently be twofold symmetrical Give cross-section and the edge of the balance somewhere in the plane of symmetry of this Place in the vessel.
Wenn der Luftdruck größer wird, steigt das Quecksilber bei K° und es fällt beiK'u. Die Waage bekommt ein gewissesÜbergewichtauf der linken Seite und der Balken senkt sich im Sinne des Pfeiles Pl. - Wenn der Luftdruck abnimmt, kehrt sich der Vorgang um, und der Waagebalken bewegt sich im Sinne P=.When the air pressure increases, the mercury increases at K ° and it falls at K'u. The scales get a certain excess weight on the left side and the bar lowers in the direction of the arrow Pl. - When the air pressure decreases, it turns the process is reversed and the balance beam moves in the sense of P =.
Man kann irgendwo an dem Waagebalken eine Schreibvorrichtung anbringen, die auf einer umlaufenden Trommel die Veränderungen des Luftdruckes aufzeichnet.You can attach a writing device anywhere on the balance beam, which records the changes in air pressure on a rotating drum.
Bei geeigneter Einrichtung kann der Ausschlag dieses Instrumentes beliebig fein und empfindlich gemacht werden, _ so ' daß man Luftdruckveränderungen wahrnehmen kann, die der Beobachtung mit den bisherigen Instrumenten verborgen bleiben.With a suitable set-up, the deflection of this instrument can be made as fine and sensitive as desired, so that there are changes in air pressure can perceive which remain hidden from observation with the previous instruments.
