Abstract

Mejoras en osciladores de batimiento de frecuencia caracterizadas por un dispositi\o para sincronizar periódicamente una corriente eléctrica alternativa que tenga unos dispositivos para generar una corriente eléctrica alternativa unos segundos dispositivos para generar una segunda corriente eléctrica alternativa de diferente frecuencia que la generada por los primeros dispositivos unos dispositivos para mezclar las dos referidas corrientes eléctricas alternativas la salida de la cual es normalmente una corriente eléctrica alternativa de una frecuencia igual a la suma o a la diferencia de las frecuencias de las corrientes generadas por los dos primeros dispositivos mencionados unos dispositivos para conectar periódicamente la salida de uno de los dos dispositivos generadores al otro de forma que uno de los referidos dispositivos generadores coerza al otro para que oscile a la misma frecuencia y en la misma fase con la corriente generada por los dispositivos coercitivos generadores y unos dispositivos para quitar periódicamente la referida conexión entre los referidos dispositivos generadores después de un periódo constante de interconexión para que los dispositivos generadores coercidos vuelvan a su modo normal de oscilación en el instante de quitar la interconexión que tiene en ese instante y en cada repetición de ese instante una relación de fase constante al otro o a los dispositivos coercitivos generadores y para que la salida de los referidos dispositivos generadores esté en la misma fase en todas las repeticiones del referido instante de quitar la interconexión.Improvements in frequency beat oscillators characterized by a device for periodically synchronizing an alternative electric current that has devices for generating an alternative electric current and second devices for generating a second alternative electric current of a different frequency than that generated by the first devices devices for mixing the two referred alternative electric currents, the output of which is normally an alternative electric current of a frequency equal to the sum or difference of the frequencies of the currents generated by the first two devices mentioned devices for periodically connecting the output from one of the two generating devices to the other in such a way that one of the referred generating devices constrains the other to oscillate at the same frequency and in the same phase with the current generated by the generating coercive devices and one s devices to periodically remove the referred connection between the referred generating devices after a constant interconnection period so that the coerced generating devices return to their normal oscillation mode at the moment of removing the interconnection that they have at that moment and in each repetition of that instant a constant phase relationship to the other or to the generating coercive devices and so that the output of said generating devices is in the same phase in all repetitions of said instant of removing the interconnection.
