Description

Najdluzszy czas trwania patentu do 25 sierpnia 1951 r.Wedlug patentu glównego Nr 23 779 wyznaczanie ,,strony" przy pelengowaniu zapomoca malej anteny pomocniczej bylo uzyskiwane przez odpowiednie oslabienie sygnalu, doprowadzonego' z ramy do obwo¬ du. Cel ten mozna osiagnac, stosujac za¬ miast transformatora autotransformator lub uklad transformujacy, zlozony z kilku indkikcyjnosci. Na fig. 1 uwidoczniono ty¬ tulem przykladu uklad, w którym przez dobranie odczepów a i b autotransformato¬ ra LI mozna uzyskac dowolne oslabienie sygnalów, p,rzyczem indukcyjnosci moga byc dobrane w ten sposób, aby wlaczenie autotransformatora nie spowodowalo prze¬ strojenia sie obwodu.Analogiczny rezultat otrzymuje sie w ukladzie wedlug fig. 2, w którym przez od¬ powiednie dobranie stosunku indukcyjno¬ sci bocznikujacej LI oraz szeregowych L2 mozna uzyskac dowolne oslabienie sygna¬ lu, przytem stosunek ten moze byc taki, aby wlaczenie cewek nie spowodowalo przestrojenia sie obwodu.Uklad powyzszy moze miec zastosowa¬ nie w ukladzie ramy obrotowej (wówczas litera L wedlug fig. 1 i 2 oznacza indukcyj- nosc ramy) oraz pirzy ramach systemu Bel- *) Wlascicielka patentu oswiadczyla, ze wynalazca jest inz. Waclaw Straszynski.lini Tosi (wówczas litera L wedlug fig. 1 i 2 oznacza indukcyjnosc radjogonjometru).Autotransformator lub uklad transfor¬ mujacy w ukladzie wedlug wynalazku moz¬ na wyposazyc w rdzenie ferromagnetycz¬ ne. PLThe longest duration of the patent until August 25, 1951. According to the main patent No. 23 779, the determination of the "side" when using a small auxiliary antenna was achieved by a corresponding weakening of the signal, which was led from the frame to the circuit. ¬ instead of a transformer, an autotransformer or a transforming system, consisting of several inductances. Fig. 1 shows a circuit with the title of an example, in which by selecting the taps a and of the autotransformer LI, it is possible to obtain any weakening of the signals, p or inductance may be selected in this way so that the switching on of the autotransformer would not cause a re-tuning of the circuit. An analogous result is obtained in the system according to Fig. it may be such that the activation of the coils does not cause the re-tuning of the circuit. the use of a rotating frame in the system (then the letter L according to Figs. 1 and 2 denotes the inductance of the frame) and the blade within the Bel- * system) The patent owner stated that the inventor was engineer Waclaw Straszynski. Figures 1 and 2 represent the radiometric inductance). The autotransformer or transformer system of the present invention may be equipped with ferromagnetic cores. PL

Claims

Patent claims. 1. A transformer system for determining the "side" according to the patent No. 23,779, characterized by the fact that an autotransformer (e.g. LI according to Eg. 1) of high frequency is included in the tuned circuit of the radiometer or the rotating frame, reducing the signal coming from the fixed frame antennas (Bellini Tosi) or the rotating frame antenna 2. Variation of the transformer system according to claim 1, characterized by the fact that instead of the autotransformer a suitable transformer, e.g. a coil, is switched on a shunt (e.g. Li according to Fig. 2) and series coils (L2) 3. A transformer circuit according to claim 1 or 2, characterized in that the auxiliary antenna is connected to the circuit directly through a resistor. 1 or 2 and 3, characterized by the fact that the windings of the autotransformer or the transformer are wound on a ferromagnetic core.
