DURING the last year, a new type of magnetron oscillations has been widely used in the Philip's laboratories. These oscillations are obtained by raising the magnetic field above the critical cut-off ...

According to Hamm, the oscillatory motion of the HD090V's rear drum reduces vibration transmitted to the operator's station, reduces sound levels for both the operator and bystanders, and prolongs ...
