Abstract: Systems and methods for three-dimensional printing using microwave assisted deposition are disclosed herein. An example device includes a reservoir of carbonaceous nanocomposite thermoset, a microwave resonance cavity that cures the carbonaceous nanocomposite thermoset, and a sensor to measure the extrusion temperature of the resin when curing the carbonaceous nanocomposite thermoset at the point of deposition during extrusion-based 3D printing.

Abstract: Tumble drying apparatus and method in which fabric articles are placed in a horizontally disposed cylindrical basket with a stringer which extends across the basket along an arcuate path that passes near the axis, and the basket is rotated about its axis with the stringer causing the fabric articles to tumble through the central portion of the basket in a loosely packed manner as they fall from one side of the basket toward the other.

Abstract: End of cycle detector and method for a microwave clothes dryer. The temperature of fabric in the dryer is monitored, an increase in the monitored temperature is detected when substantially all moisture has been removed from the fabric, and operation of the dryer is controlled in response to the increase in temperature.

Abstract: Compact microwave clothes dryer and method in which the dryer is small enough to be placed on a countertop, and air is circulated past microwave generator and power supply components to the drying chamber to transfer heat from the components to clothes in the chamber to supplement the microwave drying.

Abstract: System and method for processing extruded sponge rubber products and the like by simultaneously heating the products with microwave energy and impinging jets of high velocity hot air on the products. In one disclosed embodiment, the extruded sponge rubber parts are passed through a series of impingement rings in a microwave cavity, and each of the rings has a plurality of inwardly facing nozzles for directing jets of air in a radial direction toward the parts. Rollers transport the parts between the rings and can be driven at different speeds to accommodate elongation of the rubber parts as they expand. The microwave power is applied in pulses to provide more uniform heating of the parts, and the time base of the pulses can be changed without having to readjust the on-time of the pulses to maintain the on-time as a given percentage of the time base.
