Description

Lot- und Entfernungsmeßeinrichtung Die im Patent 699 8o4 beschriebene, mit Wechselstrom veränderlicher Frequenz betriebene Lot-.und Entfernungsmeßeiririchtung kann zur Erzielung gleicher Wirkung in besonderer Weise . auch mit Gleichstrom gespeist werden.Plumb and distance measuring device The described in patent 699 8o4, Plumb line and distance measuring device operated with alternating current of variable frequency can be used in a special way to achieve the same effect. also fed with direct current will.

Dabei muß der Gleichstrom als Anodenspannung für das gittergesteuerte Entladungsgefäß periodisch so unterbrochen werden, daß die Anodenspannung mit dem Aussenden des Sendeimpulses beginnt und jedesmal zu einem bestimmten Zeitpunkt vor Aussendung eines neuen Impulses aufhört. Dadurch erlischt die von dem inzwischen angekommenen Echo gezündete Entladung des Entladungsgefäßes. Es ergibt sich also je nach Laufzeit des Echos der `Anodenstrom als Maß für die zu messende Entfernung.The direct current must be used as the anode voltage for the grid-controlled Discharge vessel are periodically interrupted so that the anode voltage with the Sending out the transmission pulse begins and each time before a certain point in time Transmission of a new impulse ceases. As a result, the of the meanwhile expires arrived echo ignited discharge of the discharge vessel. So it turns out Depending on the transit time of the echo, the anode current as a measure of the distance to be measured.

Eine Veränderung des Meßbereiches ist durch Veränderung der Sendeimpulszahl in der , Zeiteinheit unter gleichzeitiger .sinngemäßer Änderung der periodischen Einschaltzeit der Gleichstromanodenspannung für das gittergesteuerte Entladungsgefäß möglich.A change in the measuring range is due to a change in the number of transmission pulses in the, unit of time with simultaneous, logical change in the periodic Switch-on time of the direct current anode voltage for the grid-controlled discharge vessel possible.

PATENTANSPRÜCHE: i.. Lot- und Entfernungsmeßeinrichtung nach Patent 699 804 mit Lotimpulsgeber und Empfänger, dessen verstärkter Empfangsimpuls ein gittergesteuertes Entladungsgefäß zur Zündung bringt, dadurch gekennzeichnet, daß die Anodenspannung für das gittergesteuerte Entladungsgefäß von einer periodisch so unterbrochenen Gleichstromquelle geliefert wird, daß die Anodenspannung .mit dem Aussenden des Sendeimpulses beginnt und die Spannungsunterbrechung jedesmal zu einem bestimmten Zeitpunkt vor der Aussendung eines neuen Schallimpulses erfolgt, wodurch die vom Echo gezündete Entladung in der Röhre erlischt, die somit' je nach der Laufzeit des Echos kürzere oder längere Zeit gezündet bleibt, so daß der Anodenstrom ein Maß für die zu messende Entfernung darstellt. PATENT CLAIMS: i .. Plumb and distance measuring device according to patent 699 804 with solder pulse generator and receiver whose amplified receive pulse is a brings grid-controlled discharge vessel to ignition, characterized in that the anode voltage for the grid-controlled discharge vessel from a periodic so interrupted direct current source is supplied that the anode voltage .mit the transmission of the transmission pulse begins and the voltage interruption each time takes place at a certain point in time before the emission of a new sound pulse, whereby the discharge ignited by the echo goes out in the tube, which remains ignited for a shorter or longer time depending on the duration of the echo, so that the anode current is a measure of the distance to be measured. 2. Einrichtung nach Anspruch r, da--' durch gekennzeichnet, daß die Einstellung verschiedener 1VIeßbereiche durch Vergrößerung oder Verkleinerung der Sendeimpulszähl in der Zeiteinheit unter gleichzeitiger Änderung -der periodischen Einschaltdauer der Anodenspannung für das gittergesteuerte Entladungsgefäß erfolgt.2. Establishment according to claim r, da-- 'characterized in that the setting of different measuring ranges by increasing or decreasing the transmission pulse count in the unit of time below simultaneous change of the periodic switch-on time of the anode voltage for the grid-controlled discharge vessel takes place.
