Abstract

Nuevo sistema de circuito en el cual cada aparato lleva los relé para establecer los distintos circuitos que se precisan para llamar hablar o contestar. Un relé está caracterizado por el hecho de que se imana cuando el aparato hace una llamada; otro relé está caracterizado por el hecho de que se imana cuando el aparato es llamado; un tercer relé está caracterizado por el hecho de imanarse en serie con las lámparas de señales al ser llamado el aparato y finalmente un cuarto relé que se caracteriza por imanarse gracias a haberse imanado el relé que va en serie con las lámparas de señales o bien un nuevo sistema de circuito en que cada aparato lleva una llave única para establecer las llamadas y una llave única para contestarlas. En el aparato llamado toca el timbre mientras se oprime el botón correspondiente en el aparato que hace la llamada.New circuit system in which each device carries the relays to establish the different circuits that are needed to call, speak or answer. A relay is characterized by the fact that it is magnetized when the device makes a call; another relay is characterized by the fact that it is magnetized when the device is called; A third relay is characterized by being magnetized in series with the signal lamps when the device is called and finally a fourth relay is characterized by magnetizing thanks to the relay that goes in series with the signal lamps or a new circuit system in which each device has a unique key to establish calls and a unique key to answer them. On the called device, ring the bell while pressing the corresponding button on the calling device.
