Description

Wynalazek poleca na polaczeniu kine¬ matografu z telegrafonem w celu zapisywa¬ nia i odtwarzania dzwieków telegrafonem, jednoczesnie z fotografowaniem i projekto¬ waniem obrazów kinematograficznych.Na rys- 1 schematycznie przedstawio¬ ny jest sposób polaczenia fotografujacego kinematograficznego aparatu K z tegrafo- nem T w ten sposób, ze os szpulki filmowej S fotografujacego aparatu laczy sie zapo- moca paska p z osia szpulki S', na której nawinieta jest stalowa struna / telegrafonu T. Uzwojenia elektromagnesu E telegrafo¬ nu zapomoca bat er j i ogniw B lacza sie z mi¬ krofonem M, który pod dzialaniem fal dzwiekowycih zmienia sile pradu, przeply¬ wajacego przez elektromagnes E, dzieki czemu na przesuwanej strunie / telegrafo¬ nu utrwalaja sie magnetyczne znaki dzwie¬ ków, przyjetych przez mikrofon. W ten spo¬ sób jednoczesnie z fotografowanem zapisu¬ ja sie dzwieki na strunie telegrafonu.Rys. 2 przedstawia polajcizenie tele¬ grafonu T z projekcyjnym kinematograficz¬ nym aparatem K. Os filmowej szpulki S za¬ pomoca paska p laczy sie z osia sizpulki S* telegrafonu T. Elektromagnes E telegrafonu polaczony jest z katodowym wzmacniaczem W, a ostatnii z glosnikiem M. Przy projek¬ towaniu obrazów równomiernie z filmem przesuwa sie struna telegrafonu.Magnetyczne znaki, utrwalone na stru¬ nie, wywolywuja falujacy prad w elektro¬ magnesie Et zapomcca wzmacniacza W prad ten wielokrotnie sie powieksza, poczern przechodzi do uzwojenia glosnika M, od¬ twarzajacego dzwieki, utrwalone telegrafo¬ nem. PLThe invention recommends combining a cinematograph with a telegraph in order to record and reproduce sounds with a telegraph, while photographing and projecting cinematographic images. Fig. 1 shows schematically how to connect a cinematographic camera K with a T sign in in this way, that the axis of the film spool S of the photographed camera is connected by the belt p with the axis of the spool S ', on which a steel string / telegraphone T is wound. The winding of the electromagnet E of the telegraphone by means of a battery of cells is connected with the microphone M, which under the action of sound waves changes the strength of the current flowing through the electromagnet E, thanks to which the magnetic signs of the sounds received by the microphone are fixed on the moved string / telegraph. In this way, simultaneously with the photographed, sounds are recorded on a telegraph string. 2 shows the connection of the telephoton T with a projection cinematographic apparatus K. The axis of the film spool S is connected by a strip with the axis of the spool S * of the telegraph T. The electromagnet E of the telegraph is connected to the cathode amplifier W, and the last to the loudspeaker M. When projecting images, the telegraph string moves evenly with the film. Magnetic signs fixed on the string create a rippling current in the electromagnet Et forgetting the amplifier W This current increases many times, the blackness goes to the speaker winding M, which reproduces the sounds , captured by telegraph.
