Abstract: Electromagnetic (EM) drying of a plugged ware is provided that includes subjecting the ware to an axially non-uniform EM radiation field that causes more EM radiation to be dissipated in either of the plugged regions than in the unplugged region. The EM radiation field is provided by a configurable applicator system that includes a feed waveguide and a conveyor path. The feed waveguide includes configurable slots. The configurable applicator system can be set to selectively vary the amount of EM radiation dissipated by each ware along the longitudinal axis of each ware as a function of ware position along the conveying path, thereby enhancing the EM drying process.

Abstract: A ceramic coating is provided on the outer surface of a honeycomb body by applying a first layer of coating material comprising a ceramic or ceramic-forming component to the outer surface, subjecting at least part of the first layer to at least partial curing, and then adding one or more additional layers of coating material comprising a ceramic or ceramic-forming component over the previously applied and cured layer(s).

Abstract: Methods for determining when to regenerate an exhaust gas particulate filter (10), for regenerating, and for calibrating a pressure drop across such filters are disclosed. An example method involves reducing a first amount of particulates (52) accumulated in the filter to a residual amount RADP. The method also includes measuring the residual amount RADP by exciting the microwave resonant cavity (126) in which the filter resides with microwave radiation (182) and then monitoring the microwave cavity response. The method also includes using the measured value of RADP to calibrate a pressure drop threshold ?PTH SO that it is representative of a limit (TDP) of particulate accumulation in the filter. The methods may also include regenerating the filter a number of times and each time re-setting the pressure drop threshold ?PTH based on measurements of RADP taken after each filter regeneration.

Abstract: Disclosed are systems and methods for forming glass sheets. Methods and systems are provided that comprise a refractory body configured to receive glass-based material and means for transmitting energy to selectively heat at least a portion of the refractory body through the glass-based material. In one aspect, the energy transmitted is of a selected frequency that is not fully absorbed by the glass-based material and is at least partially absorbed by the refractory body. The energy can be transmitted by a laser beam array, a scanning laser beam, a microwave generator, a radio frequency generator, or other means.
