Description

Najdluzszy czas trwania patentu do 19 lutego 1946 r.Wynalazek dotyczy odmiany lampy e- lektronowej, opisanej w patencie glównym Nr 13096, Lampa ta jest zaopatrzona w jedna lub kilka siatek oraz jedna lub kilka anod, przyczem zespól katody i siatki lub tez ka¬ tody i siatek jest otoczony nietylko anoda lub anodami, lecz takze oslona, utrzymy¬ wana pod stalem napieciem, lub kilkoma takiemi oslonami. W lampie wedlug niniej¬ szego wynalazku anoda znajduje sie we¬ wnatrz oslony. Oslona lampy wedlug wy¬ nalazku posiada szczeline, przez która przechodzi nazewnatrz przewód anodowy.Wedlug jednej z odmian wykonania prze¬ wód ten jest przymocowany zapomoca izo¬ latorów do oslony lub jej podpórek. Dzieki takiemu wykonaniu anode mozna osadzic w sposób bardzo prosty wewnatrz oslony z zapewnieniem wystarczajacej izolacji po¬ miedzy temi czesciami. Wynalazek niniej¬ szy usuwa powstawanie w lampach ladun¬ ków statycznych na szkle, przy wyrobie zas katod utlenionych, wytwarzanych zapomo¬ ca osadzania pary metalu na wlóknie kato- dowem, zapobiega rozchodzeniu sie owej|)ary po calej lampie, a zatem powstawa¬ niu zwarc, oraz umozliwia osiadanie wiek¬ szej ilosci pary metalowej na katodzie. & j, [Na jrysunku ^ prjfcfetawiono przyklad wykonania wynalazku.Fig. 1 przedstawia slupek odbiorczej lampy katodowej, fig. 2 — przekrój slup¬ ka wedlug linji /—/ na fig, 1, a fig. 3—slu¬ pek ten w widoku zgóry.Na fig. 1 cyfra 1 oznacza katode, zas cyfra 2 — siatke. Anode tworzy plytka prostokatna 3 osadzona stosunkowo da¬ leko od katody zarowej i siatki, umie¬ szczonych blisko siebie. Trzy te elek¬ trody otacza calkowicie oslona 4, po¬ laczona elektrycznie z podpórka 5, dzwigajaca srodek katody zarowej. Oslo¬ na 4 posiada (fig. 3) szczeline 6, przez która przechodzi przewód anodowy 7.Przewód ten jest polaczony zapomoca pe¬ relek szklanych 8 z trzymakami 9, przymo- cowanemi do podpórek 10 scianki 4. PL PLThe longest patent period lasted until February 19, 1946. The invention relates to a variant of the electron tube described in the main patent No. 13,096. This tube is provided with one or more grids and one or more anodes, the cathode and grid assembly or the cathode and grids being surrounded not only by the anode or anodes but also by a shield held under constant voltage, or by several such shields. In the lamp according to the present invention, the anode is located inside the shield. The shield of the lamp according to the invention has a slot through which the anode wire passes. According to one embodiment, this wire is attached to the shield or its supports by means of insulators. Thanks to this design, the anode can be mounted very simply inside the enclosure, ensuring sufficient insulation between these parts. The present invention eliminates the formation of static charges on the glass in lamps, and in the manufacture of oxidized cathodes, produced by depositing metal vapor on the cathode fiber, it prevents the spread of this charge throughout the lamp, and therefore the formation of short circuits, and allows a larger amount of metal vapor to settle on the cathode. & j, [Figure ^ shows an example embodiment of the invention. Fig. Figure 1 shows the column of a receiving cathode ray tube, Figure 2 shows the column in cross-section along the line /-/ in Figure 1, and Figure 3 shows the column in top view. In Figure 1, the number 1 denotes the cathode, and the number 2 denotes the grid. The anode is formed by a rectangular plate 3 mounted relatively far from the filament cathode and grid, which are placed close to each other. These three electrodes are completely surrounded by a shield 4, electrically connected to a support 5, which supports the center of the filament cathode. The shield 4 has (Figure 3) a slot 6 through which the anode wire 7 passes. This wire is connected by glass beads 8 to holders 9, attached to supports 10 of wall 4.
