Designing Vacuum Tube Circuits

A Vacuum Tube Micro-voltmeter for the Measurement of Bio-electric Phenomena *

1. Do living organisms possess steady state, or direct current, potential differences? 2. Can these potential differences be measured in such a way as to be free from the usual ambiguities of electrical measurement, i.e., can the determination of potential differences be made independently of resistance changes and current flow? 3. Do these potential differences reflect an unorganized chaos or ...

Vacuum mimicking phenomena in neutrino oscillations

It is shown generally that any oscillation probability in matter with approximately constant density coincides with that in vacuum to the first two nontrivial orders in ∆m 2 jk L/E if |∆m 2 jk L/E| ≪ 1 and |G F N e L| ≪ 1 are satisfied.

A vacuum tube based improved solar cooker

A new type of improved solar cooker based upon the use of a single vacuum tube is presented in this paper. The proposed cooker utilizes a solar collector consisting of parallel plane rectangular glass mirror strips mounted inside a wooden frame and requiring one dimensional solar tracking through a common driver. The proposed design can be either installed over the roof top of a house or near a...
