Abstract
Electronic preheater of plastic materials characterized by the fact that the self-oscillating circuit, which originates the electronic power for heating the plastic material deposited on the apparatus, is organized so that the cathode of the oscillating triode valve is connected to a sheet metal chassis, isolated from the box of the apparatus, and in the space between said insulated chassis and the box, a metal plate connected to the grid circuit has been interposed, through the corresponding coil, obtaining the capacity of grid due to the potential difference between said intermediate plate and the cathode chassis and the cathode capacity due to the potential difference between said chassis and the apparatus box, the air acting as a dielectric.
