Abstract: A conveyor belt cleaner and tensioning arrangement (30) for cleaning a conveyor belt including a conveyor belt cleaner (44) and a tensioner (46). The conveyor belt cleaner (44) includes one or more scraper blades (50) mounted on a rotatable cross shaft (48). The tensioner (46) includes a mounting member (90A) attached to the cross shaft (48) for conjoint rotation therewith, a resilient linear biasing member (260) attached to the mounting member (90A), and a linear actuator (284) attached to the biasing member (260). Operation of the actuator member (284) stores a biasing force within the biasing member (260) which in turn rotates the scraper blades (50) into full-face engagement with the conveyor belt with a biasing force. As the scraper blades (50) wear the biasing member continues to rotate the scraper blades (50) into full-face engagement with the conveyor belt with a biasing force that changes in magnitude. The scraper blades (50) include a front surface and a rear surface which are configured and located with respect to one another to provide a blade face surface that extends therebetween having an area which changes as the scraper blades (50) wear, in order to maintain a substantially constant contact pressure between the scraper blades (50) and the conveyor belt as the scraper blades (50) wear during use. <IMAGE>

Abstract: A microwave applicator for applying electromagnetic radiation at microwave frequency includes a coaxial input for a microwave signal input and a waveguide for receiving and propagating the microwave signal input. Dielectric material is positioned within the waveguide and extends beyond the waveguide to form an antenna for radiating microwave energy. The coaxial input has direct in-line transition to the dielectric-filled waveguide. Preferably, this direct in-line transition is achieved by the central conductor of the coaxial input extending axially centrally into the waveguide so as to excite microwaves in the waveguide. A lateral conductor extends radially from the central conductor to assist the launch of the microwaves into the waveguide. Preferably, the applicator includes a temperature sensor which is directly connected to the coaxial input.
