Description

, Wynalazek niniejszy dotyczy systemu polaczen do radiotelegraficznego nadawa¬ nia znaków, w którym narzad nadawczy moze skutecznie kontrolowac amplitude na¬ dawanych fal. Szczególy zawiera opis po¬ nizszy.Fig. 1 przedstawia uklad wedlug syste¬ mu polaczen, stanowiacego niniejszy wy¬ nalazek, fig. 2 — inny uklad takich pola¬ czen. Analogiczne czesci posiadaja jedna¬ kowe oznaczenia.Zródlo energji elektrycznej stanowi pradnica pradu stalego (co nie jest jednak ograniczeniem wynalazku), regulowana o- pornikiem 2. W obwód pradnicy wlaczo¬ na jest pojemnosc w postaci! kondensatora 5, z którym polaczona jest szeregowo cew¬ ka indukcyjna 6. Obwód ten zawiera cew¬ ki tlumikowe 3,3. Przestrzen wyladowcza 4 zamyka obwód samoindukcji 6 i pojem¬ nosci 5, powstaje wiec w ten sposób obwód drgan, który sluzyc moze za zródlo fal cia¬ glych. Samoindukcja 7 laczy nadawcza an¬ tene 8 z ziemia 9. Cewka 7 stanowic moze wtórne uzwojenie transformatora, którego pierwotne uzwojenie stanowi wspomniana juz cewka 6. Równie dobrze stosowac moz¬ na kazde inne odpowiednie polaczenie.Audjon 10, zlozony z goracych i zimnych elektrod, a wiec, np. z zimnej anody lub z skrzydelkowej elektrody 11, z siatki al¬ bo z zimne] srodkowej elektrody 12 i z go¬ racego wlókna 13, polaczony jest z obwo¬ dem anteny przewodnikiem 20, laczacym z tym obwodem zimna elektrode 11. Zaro¬ we wlókno 13 ogrzewa dowolne zródlo pra-du, np. taterja 16, regulowana oporem 17 w wiadomy sposób. Mikrofon lub inny od¬ powiedni narzad nadawczy 14 wlaczony jest pomiedzy siatka 12 i wlóknem 13. W razie potrzeby (porównaj rysunek) stoso¬ wac mozna w tym obwodzie pomocnicze zródlo pradu, np. baterje 15, której biegun ujemny, polaczony z krata, daje tej elek- trodzie ujemny ladunek, co nie ogranicza, * oczywiscie,, wynalazku.Inna odmiana (fig. 2) rózni sie tylko tern, ze mikrofon lub narzad nadawczy po¬ laczony jest z siatka dodatkowym obwo¬ dem, zawierajacym baterje 21 i pierwotne uzwojenie 19 transformatora. Wtórne u- zwojeniJe 18 tego transformatora polaczo¬ ne jest odpowiednio z siatka i wlóknem 12 i 13. Dla polaczenia mikrofonu z obwodem siatki mozna, oczywiscie, stosowac kazde inne polaczenie. W przedstawionym wy¬ padku pomocnicza baterja 22 polaczona jest z obwodem anody audjioinu i daje ano¬ dzie 11 w stosunku do wlókna 13 ladunek dodatni. W obu wypadkach plytowa elek¬ troda 11 znajduje sie w polaczeniu elek- trycznem z jedna odnoga zarowej elektro¬ dy 13. W wypadku fig. 2 zródlo pradu 22 nalezy do obwodu, stanowiacego lacznik z obwodem anteny.Przedstawione polaczenia tworza bocz¬ nikowe (równolegle do cewki 7) polacze¬ nie anteny z ziemia za posrednictwem ga¬ zu audjonu i niezaleznie od samoindukcji 7 obwodu uziemiajacego antene. Przewod¬ nictwo drogi gazowej zalezy w mniejszym lub wiekszym stopniu od kazdorazowego ladunku elektrycznego siatki 12. Wielkosc tego ladunku zalezy zkolei od narzadu na¬ dawczego, a wiec od mikrofonu 14, który reguluje potencjal, z jakim prad 15 dzia¬ la na siatke 12. Odbywa sie to albo bezpo¬ srednio (fig. 1], albo indukcyjnie lub w in¬ ny sposób dowolny (fig. 12). W ten sposób sygnal, a wiec glos, skierowany do mikro¬ fonu 14, reguluje wielkosc oporu boczniko¬ wego, powstajacego w bocznikowym ob¬ wodzie uziemiajacym antene i sprawdza tern samem zgodnosc amplitudy nadawa¬ nych fal pradami zmiennemi, przechodza- cemi przez mikrofon.Przedstawione i opisane urzadzenia sa poniekad podobne i spelniaja podobne funkcje, jak przyrzady, przedstawione na fig. 12 i 14 amerykanskiego patentu Nr 943 969 z dn. 21 grudnia 1909 roku. No¬ wosc niniejszego wynalazku stanowi zasad¬ niczy postep w sposobie regulowania na¬ dawanych amplitud zapomoca sygnalu, a wiec, np. zapomoca glosu. PLThe present invention relates to a connection system for radiotelegraphy broadcasting of signs, in which a transmitting device can effectively control the amplitude of the transmitted waves. For details, see the description below. 1 shows a circuit according to the connection system of the present invention, FIG. 2 shows another circuit of such connections. Analogous parts have the same markings. The source of electric energy is a DC generator (which, however, is not a limitation of the invention), regulated by a pillar 2. The generator circuit includes a capacity in the form of! capacitor 5, to which induction coil 6 is connected in series. This circuit includes silencer coils 3.3. The discharge space 4 completes the self-induction circuit 6 and the capacitance 5, thus creating a vibration circuit that can serve as a source of continuous waves. Self-induction 7 connects the transmitting antenna 8 with ground 9. Coil 7 may be the secondary winding of the transformer, the primary winding of which is the aforementioned coil 6. It is equally good to use any other suitable connection. Audjon 10, consisting of hot and cold electrodes, Thus, for example, from a cold anode or from a wing electrode 11, from a mesh or from a cold central electrode 12 and from a bare fiber 13, is connected to the antenna circuit by a conductor 20 which connects the cold electrode 11 to this circuit. The gold fiber 13 heats any source of electricity, for example, tateria 16, regulated by resistance 17 in a known manner. A microphone or other suitable transmitting device 14 is connected between the grid 12 and the fiber 13. If necessary (see the drawing), an auxiliary power source can be used in this circuit, e.g. a battery 15, the negative pole of which, connected to the grating, gives This electrode has a negative charge, which does not limit the invention, of course. Another variant (Fig. 2) differs only in that the microphone or the transmitting device is connected to the grid by an additional circuit containing the batteries 21 and the primary winding 19 of the transformer. The secondary winding 18 of this transformer is connected to the mesh and the strands 12 and 13, respectively. Any other connection may of course be used to connect the microphone to the circumference of the mesh. In the case illustrated, the auxiliary battery 22 is connected to the anode circuit of the audiooin and gives the anode 11 a positive charge with respect to the fiber 13. In both cases the plate electrode 11 is electrically connected to one leg of the Zero electrode 13. In the case of Fig. 2, the current source 22 belongs to a circuit which is a link with the antenna circuit. The connections shown form a shunt (in parallel). to the coil 7) connection of the antenna to the ground via the broadcast gas and independent of the self-induction of the antenna grounding circuit. The conductivity of the gas path depends, to a greater or lesser extent, on the electric charge of the grid 12. The magnitude of this charge depends in turn on the transmitting organ, i.e. on the microphone 14, which regulates the potential with which the current 15 acts on the grid 12. This is done either directly (Fig. 1) or inductively or otherwise arbitrarily (Fig. 12). In this way, the signal, i.e. the voice directed to the microphone 14, regulates the amount of the shunt resistance. resulting in the shunt grounding circuit of the antenna and checks the same amplitude compliance of the transmitted waves with alternating currents passing through the microphone. The devices shown and described are somewhat similar and perform similar functions to the devices shown in Figs. 12 and 14 of the American patent No. 943 969 of December 21, 1909. The novelty of the present invention is a fundamental advance in the method of adjusting the given amplitudes of the signal assistance, and thus, for example, of the voice. PL
