Claims

With the previous storage of the cathode ray tubes, which were installed in a base similar to the incandescent lamp and rigidly attached to the base, 'j the inconvenience shown that the filament is shaken and thereby changes the distance between the filament and the auxiliary electrode. At; .the Use of such tubes for reception for

ίο wireless telegraph then shows up annoying ringing on the reception phone.

According to the present invention, this is avoided in that a damping device is connected between the tube base and the fastening arrangement, which attenuates or completely prevents the transmission of vibrations from the base to the tube. ■ ^:. .

The drawing shows an exemplary embodiment of an arrangement according to the inventive concept identified above. . '.' .. · ■■ ^"■::: ^{'■■:;:.....} A claimed in train coil spring 2 is connected to the base plate 1 and of the cover

^ 5. Disk 5 firmly connected. Brass bushes that are too small on the inside sit on these discs 3, between which compression springs 4 are inserted. i Jas whole forms an elastic system that

3 '! a springing of the disk 5 downwards and obi-n, as well as a small rotation about the axis ″ of the spiral spring · 2. Supports 6 are attached to the base plate 1 and carry a connecting ring 7 at the top. From this go down leaf springs 8, which spring against the base 9 on which the cathode ray tube 10 is attached. The arrangement of the springs 8 is desirable because such vibrations, which could set the lower elastic system in resonance, are thereby canceled . ■:,. < ■ -.- ^:. ■ "■. '■ ^.: · ■.'

The elastic system can also be replaced by a felt or similar intermediate layer ^: "Be. ■ · '-.' ■. ■ ·;. '." .-.
