RADIO WITH-YACUUM CHAMBER Filed Aug. 24,v 1942 INVENTOR Patented Aug. 1, 1944 UNITED STATES PATENT OFFICE RADIO WITH VACUUM CHAMBER Abraham Binneweg, Jr., Oakland, Calif.
Application August 24, 1942, Serial No. 455,857
1 Claim. v('Cl. Z50-27.5)
My invention relates to improvements in vacuum tubes and the object of my improvement is to provide a compact radio cabinet with several compartments and especially with a vacuum sealed compartment containing multiple units connected by short leads for ultra short wave reception or transmission. Other objects are to provide special mountings for cathodes, grids, plates, and condensers to make possible very close connections within the vacuum chamber; and to provide a compact arrangement oi loud-speaker, antenna, rectier, and detecting or transmitting units. Other objects will appear from the following description:
Figure I is a plan View of the cabinet with top covers removed,
Figure II is a vertical section of the cabinet giving an interior view.
'Ihe radio cabinet is enclosed by walls I, base 2, and cover 3. It contains a compartment 4 holding a loudspeaker 5, and a compartment 6 holding a parabolic cylindrical reflector 1, and the telescoping rod antenna 28. The sealed vacuum chamber 8 contains such elements as a holder 9 with standards I0, supporting adjustable condenser plates II with leads I2, holders I3 with notched standards I4, supporting cathodes I 5,v
multiple grids I6, and plates I1; and the radio frequency transformer I8. Screws` I9, passing through cover 20 and gasket 2| into threaded holes 22, serve to make the chamber air-tight. It is then evacuated through tubes 23 cemented or threaded into the cover 20, and the tubes pinched o'.
In the past each set of plate, grid, and cathode elements have been placed in a separate tube, and the considerable length of the leads between tubes has lengthened the wavelength being transmitted. By placing several sets of such elements in a common vacuum chamber my improvement makes possible shorter connections between elements and a more flexible arrangement for securing a minimum of inductance and consequent ultra short waves. Condensers, radio frequency transformers, resonance coils, and any other parts desired may, by my device, be enclosed in the same chamber. For multiple stage amplication any number of element sets may be enclosed in one chamber and connected in any manner desired.
By providing a removable cover 20 for the vacuum chamber 8, and multiple or removable threaded exhaust tubes 23, it is possible to open the chamber at any time for the replacement, substitution, or rearrangement of elements, and then to replace the cover and reexhaust the chamber. The vacuum chamber 8, of glass, plastic, or other dielectric material, may be entirely removed from the cabinet ii desired and replaced by another.
Cooperating groups of elements, such as cathodes, grids, and plates, are placed upon plastic, glass, or porcelain mounts I3 having grooved standards I4 to hold them in proper relation. The design of these mounts makes possible sucient spacing and insulation for the very high voltages employed in transmission.
I claim:
A unit for a radio tube comprising a dielectric base, standards rising from said base and integral therewith, notches in the top of said standard, and cathode, grid, and plate elements suspended between said standards and held in place by said notches.
