notes: label: Description (Brief)
content: Small cylindrical glass tube with exhaust tip on one end and contacts on the other. Donor’s card reads: “Proximity fuse tube made by the Sylvania Corporation of Emporium, PA. Known originally as T-3 tubes. Four or five of these tubes of various designs were incorporated in a fuse for anti-aircraft shells which would explode the shell on approaching any solid mass.
label: Description (Brief)
content: An oscillator in the nose of the fuse radiated a steady UHF signal. When this signal hit any solid mass it was reflected back to the fuse, where, due to the Doppler Effect, the returned signal was of a different frequency from that transmitted. This difference in frequency produced a beat which was used to operate a thyratron tube in direct control of the fuse ignition.”
