Description

Gemäß der Erfindung werden Zeitsignale, für die es auf besondere Genauigkeit ankommt, durch den Entladungsstrom eines Kondensators gegeben, und zwar wird dabei der Kondensator über eine Selbstinduktion und einen Ohmschen Widerstand entladen, die beide so bemessen sind, daß die Entladung nur eine bestimmte, durch die vorgeschriebene Genauigkeit gegebene Zeitdauer'beansprucht. EinAccording to the invention, time signals for which particular accuracy is important are given by the discharge current of a capacitor, namely the capacitor discharged via a self-induction and an ohmic resistance, both of which are dimensioned so that the discharge is only one certain period of time given by the prescribed accuracy. A

ίο Zeitsignal kann nämlich nur dann Anspruch auf Genauigkeit machen, wenn seine eigene Zeitdauer nicht schon so groß ist, daß sie die gestattete Fehlergrenze selbst überschreitet. Bei hohen Anforderungen an die Genauigkeit muß also die Zeitdauer des Signals selbst auch genau bemessen sein, und für diese Bemessung ist der Kondensator mit seinem Entladungsstrom ein ebenso einfaches wie einwandfrei arbeitendes" Mittel. Er ermöglicht es, das Signal sowohl durch Drahtleitungen wie auch funkentelegraphisch in die Ferne zu übermitteln.ίο time signal can only claim make for accuracy, if its own duration is not already so great that it does the permissible error limit itself exceeds. With high demands on accuracy So the duration of the signal itself must also be precisely measured, and for this dimensioning the capacitor with its discharge current is as simple as it is flawless working "means. It allows the signal to pass both through wired lines as well as to transmit by radio telegraph to the distance.

Das Ausführungsbeispiel einer Einrichtung gemäß der Erfindung ist in der ZeichnungThe embodiment of a device according to the invention is shown in the drawing

»5 dargestellt. Ein Kondensator 1 ist durch einen Umschalter 2 mit einer Batterie 3 verbunden, wenn der Umschalter 2 in der punktiert angedeuteten Stellung steht. Sobald das Zeitsignal gegeben werden soll, wird er in die ausgezogen dargestellte Lage umgelegt. Dann fließt der Entladungsstrom über einen Ohmschen Widerstand 4 und eine Selbstinduktion 5, die zusammen so bemessen sind, daß die Entladung des Kondensators innerhalb einer Zeitdauer beendet ist, die unterhalb der gestatteten Fehlergrenze liegt. Durch den in der Selbstinduktion 5 abnehmenden Entladungsstrom wird in einer Spule 6 ein Strom induziert, der einen Kondensator 7 aufladet. Es entstehen dann in der Löschfunkenstrecke 9 eine Reihe von Teilentladungen, deren jede in dem durch die Kapazität 7 und die Selbstinduktion 8 gebildeten Schwingungskreis gedämpfte Schwingungen hervorruft. Diese erregen einen abgestimmten Schwingungskreis, der durch Selbstinduktionen 10 und 11 und eine Kapazität 12 gebildet wird. Die durch die Spule 11 gehenden Schwingungen werden durch eine Antenne 12 ausgesandt. Die Sicherheit, mit der der Entladungskreds des Kondensators 1 berechnet und gebaut werden kann, leistet unbedingte Gewähr dafür, daß die Dauer der ausgesandten Signale die vorgeschriebene Zeit genau innehält. »5 shown. A capacitor 1 is through a changeover switch 2 is connected to a battery 3 when the changeover switch 2 is punctured in the indicated position. As soon as the time signal is to be given, it will be in the position shown in solid lines turned over. Then the discharge current flows through one Ohmic resistance 4 and a self-induction 5, which together are dimensioned so that the discharge of the capacitor is completed within a period of time below the permitted error limit is. By decreasing in the self-induction 5 Discharge current, a current is induced in a coil 6, which has a capacitor 7 charges. A series of partial discharges then arise in the quenching spark gap 9, each of which in the oscillation circuit formed by the capacitance 7 and the self-induction 8 causes damped vibrations. These excite a co-ordinated one Oscillating circuit formed by self-inductions 10 and 11 and a capacitance 12 will. The vibrations passing through the coil 11 are detected by an antenna 12 sent out. The certainty with which the discharge credit of the capacitor 1 is calculated and can be built provides an unconditional guarantee that the duration of the sent Signals precisely pauses the prescribed time.
