Abstract
In the course of a research on the effects produced on the wave-length of the oscillations given out by a triode maintained oscillator when various changes were made in the circuit, Eccles and Vincent showed that in an oscillatory circuit maintained by a B valve with a grid coil coupling (like the two oscillatory circuits in fig. 1) the wave-length varies slightly with the filament current and has a maximum value for a certain filament current. In all cases investigated it was found possible so to adjust the coupling between the grid coil and main oscillator coil as to allow the filament current to be set to make the wave-length a maximum.
