Abstract: A microwave applicator for heating materials with microwaves. A coaxial transmission line is inserted in the material and coupled at one end to a source of microwaves. A shorting plate covers the other end of the cable and a plurality of radiating apertures are provided along the outer conductor. The use of a coaxial line avoids the minimum size requirements present with hollow waveguides. The coaxial line may be directly coupled to the output probe of a microwave generator by means of spring-finger contacts on the inner conductor of the coaxial line.

Abstract: The control system monitors the input power to and the output from the dryer applicator, and varies the input power to the applicator as a function of change in applicator efficiency and input power. The control system may consist of a first and a second circuit. The first circuit receives a signal P.sub.in.sbsb.1 from a first monitor and a signal P.sub.out.sbsb.1 from a second monitor. These signals are combined into an efficiency signal .eta..sub.1 to which a reference efficiency signal -.eta..sub.o is added. An amplifier having a predetermined gain K amplifies the resulting signal to produce -K(.eta..sub.1 -.eta..sub.o). The second circuit adds the signals P.sub.in.sbsb.1 from the first monitor, -K(.eta..sub.1 -.eta..sub.o) from the first circuit and P.sub.in.sbsb.o, a signal representative of input power for a reference condition, to produce an output signal I.sub.in.sbsb.1 - [P.sub.in.sbsb.o + K(.eta..sub.1 -.eta..sub.o)] which is coupled to the microwave source to control the input power to the applicator. The reference signal P.sub.in.sbsb.o may be generated by a voltage source as a function of transport speed of the load through the applicator.

Abstract: The single-sided microwave applicator has a section of a microwave waveguide with an open end for receiving microwave energy and an end which is electrically shorted. A slot is located in one of the wide sides of the waveguide extending along the center line from the shorted end. A conductive ridge is mounted within the waveguide extending upward from the other side through the slot. One end of the ridge is connected to the shorted end of the waveguide, while the other end of the ridge is tapered from a point within the slot. The slot is generally in the order of 3/4 to 1 inch and at least 21/2 inches long, when the operating frequency is 2450 MHz. Since one end of the waveguide is shorted, standing waves are produced resulting in a non-uniform field having at least one maximum along the length of the slot. The electric field produced is non-radiating and its strength diminishes exponentially above the slot.

Abstract: The scanning microwave detection apparatus provides a moisture profile along the width of a predetermined sample such as a sheet or web. The apparatus includes a number of moisture sensors spaced along the width of the sample, such that each sensor couples microwave energy with a finite area of the sample. Each sensor is preferably a pair of horns with one located on each side of the sample to provide a microwave path through the sample. A first filter is coupled to the input of each sensor and a second filter is coupled to the output of each sensor. The pair of filters associated with each sensor is tuned to the same frequency, and each of the pairs of filters are tuned to a different predetermined frequency within a selected frequency band such that the sensors operate at different frequencies, within substantially non-overlapping frequency band-passes. The filters are preferably directional. A microwave source is coupled to the input filters and is controlled to sweep through the selected frequency band to sequentially energize each sensor. A detector is coupled to the output filters for detecting the sequential energy outputs of the sensors. These sequential outputs are a function of the moisture content of the finite areas of the sample at the sensors.
