Abstract: A process for heating a powder material by microwave radiation so that heating of the powder material is selective and sufficient to cause complete melting of the particles. The process entails providing a mass of powder comprising a quantity of filler particles of a metallic composition, and subjecting the mass to microwave radiation so that the filler particles within the mass couple with the microwave radiation and are completely melted. According to one aspect, the mass further contains at least one constituent that is more highly susceptible to microwave radiation than the filler particles, and the filler particles are melted as a result of heating by microwave radiation and thermal contact with the at least one constituent. According to another aspect, the powder mass is thermally pretreated to induce an irreversible increase in its dielectric loss factor prior to melting by microwave irradiation.

Abstract: FIG. 1 depicts a full view of the picnic table backrest. It shows the backrest, the bars that wrap around the bench to keep the back rest stable and the latch on the back of the rest that keeps the rest from slipping out. FIG. 2 shows a close up view of the latch on the rear of the backrest. The bar that holds the latch swivels upward to latch on to the top part of the backrest. This keeps the backrest from slipping out and also holds it in place so it doesn't shift while your sitting.

Abstract: Indentation patterns in microwave packaging materials can enhance the baking and browning effects of the microwave packaging materials on food. The indentation patterns can provide venting to either channel moisture from one area of the food product to another, trap moisture in a certain area to prevent it from escaping, or channel the moisture completely away from the food product. The indentation patterns can cause the microwave packaging material underneath a food product to be slightly elevated above the cooking platform in the base of a microwave. The indentation patterns can lessen the heat sinking effect of the cooking platform by providing an air gap for insulation. Elevating the base of the microwave packaging material further allows more incident microwave radiation to propagate underneath the microwave packaging material to be absorbed by the food product or by microwave interactive materials in the microwave packaging material that augment the heating process.
