Abstract

585,403. Dielectric heating. MACMILLIN, H. F. May 1, 1944, No. 8146. Convention date, April 15, 1943. [Class 39 (iii)] [Also in Groups V and XVIII] Plastic material 105a in a chamber 40 is heated by the insertion therein of a high tension electrode 86, the frame 10 of a moulding machine constituting the low tension electrode. The electrode 86 is secured, through an insulating bushing 88 to a hydraulic piston rod 89, and reciprocates within an insulating bushing 87 in the machine frame. An insulating bushing 95 retains alignment between the electrode and the chamber.
