Description

Im Patent 901 000 ist eine Gruppe von Strahlern beschrieben, die akustische oder elektromagnetische Wellen unterschiedlicher Frequenz abstrahlen. Dadurch kann z. B. eine selbsttätige Änderung der Strahlungerichtung oder in einem Sonderfall eine Abstrahlung von Schwingungen bestimmter Kennung, ζ. B. zur Erhöhung der Selektion in Unterwassersignalanlagen, erzielt werden. Zur Erzeugung der verschiedenen Frequenzen sind im Patent 901 000 verschiedene Bauarten von Generatoren vorgeschlagen, durch die die einzelnen Strahler mit den vorgeschriebenen Frequenzen bei periodisch wiederkehrender gleicher Phasenlage betrieben werden.Patent 901,000 describes a group of radiators, acoustic or electromagnetic Radiate waves of different frequencies. This allows z. B. an automatic change of Direction of radiation or, in a special case, radiation of certain vibrations Identifier, ζ. B. to increase the selection in underwater signal systems can be achieved. To the generation of the different frequencies are different types of generators in patent 901 000 suggested that the individual radiators with the prescribed frequencies at be operated periodically recurring the same phase position.

Gemäß der Erfindung läßt sich eine besonders einfache Einrichtung zur gleichzeitigen Abstrahlung verschiedener Frequenzen dadurch erzielen, daß für jede Frequenz ein auf sie abgestimmter Strahler vorgesehen ist und daß die Strahler durch gemeinsame, vorzugsweise gleichzeitige Stoßerregung (Schallsender, z. B. durch Anstoß mittels Kondensatorentladung) zum Schwingen in ihren Eigenfrequenzen, angeregt werden.According to the invention, a particularly simple device for simultaneous radiation can be used different frequencies by having a tuned for each frequency Radiator is provided and that the radiator by common, preferably simultaneous shock excitation (Sound transmitter, e.g. when triggered by a capacitor discharge) to vibrate in their Natural frequencies, are excited.
