    Abstract: A preferred embodiment of a fire containment system is implemented in a combination washer-dryer appliance equipped with air-vented exhaust. A fire suppression fluid conduit connected between a cold water valve outlet and a fire suppression fluid inlet positioned in a top portion of a tub of the appliance provides a path of cold water flow into an interior space of the tub. A valve control signal applied to a valve actuator associated with the cold water valve outlet actuates it upon a presumed occurrence of presence of fire in the interior space, as indicated by an electromechanical switch set in the top portion of the tub to measure an internal temperature of the interior space. The valve control signal thereby causes cold water flow through the fire suppression fluid conduit and into the interior space of the tub to contain and extinguish a fire burning within it.

  • Publication number: 20100107435
    Abstract: Methods and apparatus for drying ceramic green bodies include providing one or more ceramic green bodies in a microwave heating chamber operatively connected to a microwave source and a PLC. The total mass of the ceramic green bodies present in the microwave heating chamber is determined. Microwave energy is generated with the microwave source and transmitted from the microwave source to the microwave heating chamber. A transmitted power of the microwave energy transmitted from the microwave source to the microwave heating chamber is measured with power sensors. The reflected power of reflected microwave energy reflected back from the microwave heating chamber is also measured. The power of the microwave energy transmitted from the microwave source to the microwave heating chamber is adjusted based on the total mass of ceramic green bodies present in the microwave heating chamber, the measured transmitted power and the measured reflected power.

  • Publication number: 20100059508
    Abstract: This document discloses semiconductor processing systems, methods, and devices. The systems, methods and devices activate dopants in a processing chamber having a temperature that is less than, for example, 300 degrees. A microwave energy source provides a microwave transmission to a waveguide system that uniformly distributes the microwave transmission. The waveguide system can include a rectangular waveguide coupled to a cylindrical waveguide. The rectangular waveguide guides the microwave transmission in a second propagation direction to a cylindrical waveguide. The cylindrical waveguide uniformly distributes the electromagnetic transmission and guides the electromagnetic transmission in a third propagation direction to a processing chamber. A semiconductor wafer can be exposed to the microwave transmission and the temperature of the chamber to activate dopants in the semiconductor wafer.

  • Publication number: 20090321429
    Abstract: Generally and not exclusively, a microwave cooking oven to cook food in a microwave chamber (e.g., a cooking chamber) includes a microwave power source, and a microwave control unit. The control unit includes a microwave detector to detect the microwave power in the cooking chamber, and a control circuit to determine the food optical density or food temperature, based on the microwave power being absorbed by the food. The control circuit determines the microwave power being absorbed based on the difference between the power emitted into the cooking chamber and the power detected within the cooking chamber. In one illustrative embodiment, microwave power is emitted by multiple ports from different directions, and the microwave power absorbed by the food along these different directions is measured. The control circuit then determines the optical density or temperature of the food along each direction.

  • Patent number: 7560673
    Abstract: An apparatus for controlling agricultural pests in soil using microwave energy. The apparatus is an agricultural implement having a means for directing a layer of soil from the ground onto a conveyor which carries the soil through a microwave energy application area, and then disperses the soil back onto the ground. The microwave energy heats the soil to a desired temperature which destroys weeds, seeds, and insects in the soil.

  • Patent number: 7501608
    Abstract: The present invention provides a microwave oven and a method of operating a microwave oven, which minimises user involvement when heating a food item to a desired target temperature. According to the invention, the initial temperature of the food item is measured prior to the heating process, and the required heating time is determined automatically based on the initial temperature, the target temperature, and the amount of food as entered by the user. In order to heat a food item to a desired target temperature, the user only needs to position a container for temperature measurement and enter the amount of food. In particular, the present invention is preferably adapted for heating of baby food, such as baby milk contained in a baby bottle, and in such case the target temperature is preferably preset to about 37° C.

    Abstract: A system for microwave assisted high-throughput chemical processes is disclosed. The system includes a source of microwave radiation, a microwave cavity in communication with the source, and a microtiter plate in the cavity. The microtiter plate is formed of a microwave transparent material and includes a plurality of sample wells. A fluid chamber is defined by the interior of the four walls, the base, the profiles of the wells, and by the top surface of the microtiter plate. A microwave-moderating fluid in the chamber helps produce a more uniform microwave field among the individual wells in the microtiter plate when microwaves are applied in the cavity from the source.
