Abstract

A combination of a microwave generator with a tubular waveguide for transmitting UHF waves in the TEO1 mode and screens for localising the heating to a specific zone of a profile mounted concentrically in the waveguide. Pref. an internal coaxial tube made of a low dielectric loss material butts against the end of the profile being heated. Pref. the screens can be traversed to vary the zone which is softened. The open end of the guide is loaded with a jacket of material which absorbs hyperfrequency energy. Esp. suitable for softening thermoplastic pipe ends, e.g. PVC, prior to forming a socket for a fusion joint using frequencies of 2450 MHz. Offers rapid heat generation through thick walled pipe without risk of hot spots or the need for part rotation.
