Description

  

   <Desc/Clms Page number 1> 
 



    Vomchtung zur Messung ideiner Zeitintervalle.   
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 



   Da das zumessende Ereignis   gewöhnlich   von sehr kurzer Dauer ist, genügt in den meisten Fällen ein einmaliges Anschlagen der Stimmgabel. 



   Je nach der Art des zu messenden Vorganges wird sich gegebenenfalls die Verwendung mechanischer optischer oder akustischer   Hilfvorrichtungen   zur Aufnahme bzw. Übertragung der Phasen desselben auf den Spiegel bzw. zur Beeinflussung des Lichtbündels empfehlen. So kann der Spiegel beispielsweise auf einer Telephonmembrane angeordnet werden. Zur Messung der Geschwindigkeit drehender Bewegungen kann das   Lichtbündel   selbst durch eine mit gleicher Geschwindigkeit rotierende Blende unterbrochen werden. Bei Anordnung von   Bürstenkontakten   und einer Funkenstrecke können die auftretenden Funken mittels eines feststehenden Spiegels auf die Bildfläche projiziert werden.

    Precaution for measuring id of time intervals.
 EMI1.1
 

 <Desc / Clms Page number 2>

 



   Since the event to be measured is usually of very short duration, in most cases it is sufficient to strike the tuning fork once.



   Depending on the type of process to be measured, it may be advisable to use mechanical optical or acoustic auxiliary devices to record or transmit the phases of the same to the mirror or to influence the light beam. For example, the mirror can be placed on a telephone membrane. To measure the speed of rotating movements, the light beam itself can be interrupted by a diaphragm rotating at the same speed. When brush contacts and a spark gap are arranged, the sparks that occur can be projected onto the screen using a fixed mirror.

PATENT-ANSPRUCH : Vorrichtung zur Me3sung kleiner Z'3itintervaIIe, bei der unter Verwendung von Stimmgabel und EMI2.1 gerade Linie und daneben laufend eine Sinu linie photographi eh aufgezeichnet werden, dadurch gekenn- zeichnet, dass von zwei in einem Doppeldrehspuleninstrument angeordneten Spiegeln (8 und 9), die von zwei einer Lichtquelle entstammende und durch Spiegel (10 und 11) weitergeleiteten Strahlenbündeln getroffen werden, der eine, durch die Schwingungen einer Stimmgabel, der andere, von einem die einzelnen Phasen des zu messenden Ereignisses registrierenden Instrumentes auf elektrischem Wege beeinflusst wird. EMI2.2 PATENT CLAIM: Device for measuring small time intervals, with the use of tuning fork and EMI2.1 straight line and a continuous Sinu linie photographi are recorded anyway, characterized by the fact that two mirrors (8 and 9) arranged in a double rotating coil instrument hit the bundles of rays from two light sources and transmitted by mirrors (10 and 11) one is influenced by the vibrations of a tuning fork, the other by an instrument that records the individual phases of the event to be measured.
