Bf WIENECKE TUBE FOR SHORT WAVES Original Filed Mar ch s, 1935 Fatented Apr. 4, 1939 UNITED STATES TUBE FOR SHORT WAVES Bruno Wienecke, Berlin, Germany, assignor to Radioaktiengesellschaft D. S. Loewe, Berlin- Steglitz, Germany Original application March 8, 1935, Serial No. 10,046. Divided and this application June 2'7,
1936, Serial No. 87,697. 1934 1 Claim.
In tubes for short waves, both for transmission as Well as for amplifying purposes, it is favourable to make the leads to the electrodes as short as possible. In the case of comparatively long electrodes the leads should be taken to the middle, so that the natural Wave will be as short as possible.
Tubes are known in which the lead of the grid is taken to its middle through an opening in the anode and the leads of the grid and of the anode are passed out towards opposite sides.
According to the invention, in order toobtain high emission the cathode is made of more than two parallel filaments lying in a plane, and consequently a grid of oval cross-section is used.
The present invention is illustrated by the accompanying drawing in which Fig. 1 is a longitudinal section through the tube, whilst Fig. 2 is a side view.
In the drawing, l is the cathode, for an example consisting of 4 parallel filaments, 2 the anode and 3 the grid, both of oval cross-section. The lead 4 to the grid is connected to its mid- In Germany March 13,
zone and is passed through an opening in the anode. The lead 5 to the anode is also connected to its mid-zone. Both leads are conducted out of the bulb 9 at opposite sides.
The high-frequency leads 6--6 to the cathode are arranged perpendicular to the above leads and pass through the walls of the bulb at opposite sides whilst the heating current is conducted to the filaments via the plugs l and 8 arranged at the base of the bulb.
I claim:
A tube for short waves comprising a bulb, a cathode, a grid and an anode, a lead being conducted from the mid-zone of said anode outside of said bulb, another lead being conducted from the mid-zone of the grid through an opening in the opposite side of said anode also outside of the bulb, and two plugs on the base of said bulb, the high-frequency leads from said cathode being conducted out of said bulb perpendicular to said leads from grid and anode, the heating current conducting leads to said cathode being connected to said plugs.
BRUNO WIENECKE.
