<p>A resonant chamber is used for heat treatment of certain materials of suitable absorbent qualities to high frequency waves. The waves from an antenna at one end of a box are directed towards the material to be treated which passes continuously over a slit in the upper wall of the box. The slit is adjustable in shape and a further modification is in the provision of a wedge within the box which helps to concentrate the waves on the material to be treated. Suitable for material of large dimensions and of suitable absorbing qualities.</p> |
