TUBE FOR SHORT WAVES Filed March a, 1935 inventor Patented Sept. 6,1938
UNITED STATES PATENT otter.
Application March 8, 1935, Serial No. 10,046 In Germany March 13, 1934 2 Claims.
In tubes for short waves, both for transmission as well as for amplifying purposes, it is 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.
According to the invention, this is performed in the case of the-grid by the fact that the lead thereto is taken to its middle through an opening in the anode.
In Fig. 1, l is the cathode, 2 the anode, and 3 the grid, which is connected at its centre at one or, as illustrated by way of example, at two points with the leads 4 through openings in the anode. The anode is led out for example vertically thereto at 5.
Figure 2 is a horizontal cross-sectional view through the cathode I of Fig. 1.
I claim: 7
l. A tube for short waves comprising a cathode, a grid, and an anode, two leads connected to the centre of said grid and passed through two openings in said anode, said leads being directed towards opposite sides.
2. An electronic tube for very high frequencies comprising a bulb, a cathode, a grid and an anode, two leads connected to the mid-zone of said grid and passed through two openings in the mid-zone of said anode, said grid leads being directed towards opposite sides, these leads and the leads or said cathode and said anode passed out of the bulb in three directions spaced perpendicular to each other.
