Description

Najdluzszy czas trwania patentu do 11 maja 1942 r.Negadyna zbudowana jest wedlug zwy¬ klego -schematu z czesci zlozonych z zacho¬ waniem ostroznosci zwyklych przy mon¬ towaniu odbiorników, to znaczy przewo¬ dami golemi jak naijkrótszemi i w mozliwie najwiekszej odleglosci jednego przewodu od drugiego, Negadyna sklada sie jak zwy¬ kle z czesci nastepujacych, jak pokazane na schemacie zalaczonym na rysunku obok: antena 1 polaczona z cewka antenowa 2 o dziesieciu do dwudziestu zwojach wymia¬ rów zwyklych, koniec cewki 2 polaczony do uziemienia 3. Cewka antenowa 2 sprze¬ zona jest z cewka negadyny 9 kilkudzie¬ sieciu do stu kilkudziesieciu zwojów za¬ leznie od dlugosci przyjmowanej fali. Cew¬ ka negadyny 9 polaczona jest jednym kon¬ cem z jednym biegunem kondensatora zmiennego 4 o pojemnosci kolo 500 cm, z jednym biegunem kondensatora stalego 5 o pojemnosci okolo 250 cm i siatka we¬ wnetrzna lampki dwusiatkowej 7; drugi koniec cewki negadyny 9 polaczony jest z drugim biegunem kondensatora zmiennego 4 w punkcie 13. Drugi biegun kondensato¬ ra stalego 5 polaczony jest z siatka we¬ wnetrzna 6 lampki dwusiatkowej i z jed¬ nym biegunem oporu okolo 2000000 omów 8; drugi biegun oporu 8 polaczony jest z dodatnim biegunem ba ter j i zarzenia 15 i odpowiednim zaciskiem nitki zarzenia w lampce. Ujemny biegun batetrji zarzenia 11 polaczony jest przez opornik 10 z od¬ powiednim zaciskiem nitki zarzenia wlampce. Anoda lampki radj owej 18 polaczo¬ na jyest z minusem sluchawki 17, albo z wej¬ sciem uzwojenia pierwotnego transformatora malej czestotliwosci. Biegun dodatni 15 ba- terji zarzenia, polaczony jest jesizcze z bie¬ gunem ujemnym ba ter j i anodowej. Biegun dodatni baterji anodowej 12 polaczony jest z punktem 13 wspólnym dla cewki i kon¬ densatora 4. Przed lampa negadyny moga byc wlaczane jedna lub wiecej lamp wiel¬ kiej czestotliwoscL Nastepnie pomiedzy ziwyklym oporem pozotraym obwodu ano¬ dowego negadyny, to jest sluchawka, albo transformator w punkcie 19 i punkt wspól¬ ny 13 wstawia sie w obwód oscylacyjny dla wytworzenia isuperreakcji, to jest cew¬ ke 14 o 1 000 do 1 500 zwojów masowa, lub. komórkowa i o 100 000 (sto tysiecy) do 150 000 (sto piecdziesiat tysiecy) mikro- henry samoindukcji i kondensator równo¬ legly do tej cewki 16 o pojemnosci okolo 2 000 cm (okolo 0,002 mikrofarada); obwód dodatkowy pokazany jest na rysunku lin ja gruba przerywana. Poza tern uklad apara¬ tu jest znów zwykly, to znaczy, ze w punktach 17 i 19 wlaczotna jest sluchawka lub wzmacniacz malej czestotliwosci. PL PLThe longest term of the patent, until May 11, 1942, Negadyna is built according to the usual scheme of parts assembled with the caution usual when assembling receivers, i.e. with bare wires as short as possible and with the greatest possible distance from one wire to the other. As usual, the Negadyn consists of the following parts, as shown in the diagram attached to the right: antenna 1 connected to antenna coil 2 of ten to twenty common dimensions, coil end 2 connected to ground 3. Antenna coil 2 connected The line is from the negadin coil 9 of a few tens of a network to a hundred and several dozen turns depending on the length of the received wave. The negadin coil 9 is connected at one end to one pole of a variable capacitor 4 with a capacity of about 500 cm, with one pole of a fixed capacitor 5 with a capacity of about 250 cm and an internal grid of a double-tube lamp 7; the other end of the negadin coil 9 is connected to the other pole of the variable capacitor 4 at point 13. The other pole of the fixed capacitor 5 is connected to the internal grid 6 of the double-grid lamp and one pole of a resistance of about 2,000,000 ohms 8; the other pole of the resistance 8 is connected to the positive pole of the bulb and the glow 15 and the corresponding clamp of the glow thread in the lamp. The negative pole of the glow line 11 is connected via a resistor 10 to the corresponding terminal of the glow thread in the tube. The anode of the radio lamp 18 is connected to the negative of the handset 17, or to the input of the primary winding of the low-frequency transformer. The positive pole of the glow bulb is connected to the negative pole of the anode battery. The positive pole of the anode battery 12 is connected to the point 13 common to the coil and capacitor 4. Before the negadin lamp, one or more high-frequency lamps may be switched on. Then, between the cyclic resistance of the negadin's anode circuit, that is, a handset or a transformer. at point 19 and point 13, an oscillatory circuit is inserted into the oscillatory circuit to produce an super-reaction, i.e., coil 14 with 1,000 to 1,500 mass turns, or. cellular and about 100,000 (one hundred thousand) to 150,000 (one hundred and fifty thousand) micro-induction micro-hens and a capacitor parallel to this coil 16 having a capacity of about 2,000 cm (about 0.002 microfarad); The additional circuit is shown in the drawing of the ropes as thick, broken. Outside of this, the apparatus layout is normal again, that is, the handset or the low-frequency amplifier is on at points 17 and 19. PL PL
