  • Publication number: 20100301036
    Abstract: Methods are presented for modifying a physical property of a structure, such as reducing or relieving remaining internal stress, in which two or more energy types are concurrently applied to the structure to change the physical property of interest in an accelerated fashion. A first energy type, such as heat, is applied according to time values and operational settings derived from a first order rate relationship for the first energy type and from a first order rate relationship for a second energy type. The second energy type, such as vibration or other time-varying energy form, is applied concurrently for the time value. Methods are also provided for determining operational settings for concurrent application of multiple energy types to a structure.

  • Patent number: 7829828
    Abstract: An instrument for carrying out controlled microwave assisted chemical processes, and that is particularly useful for handling relatively small samples. The instrument includes a microwave-transparent reaction vessel with an open mouth, a pressure-resistant seal on the mouth of the vessel, and a needle, portions of which penetrate the seal with a first end of the needle and provide fluid communication into the vessel. A pressure transducer is at the opposite end of the needle and in fluid communication with the interior of the vessel through the needle. The instrument defines a pressure control flow path from a portion of the needle outside of the vessel to a fluid port, the flow path being in communication with the needle, the interior of the vessel and the transducer. A controllable pressure release valve for the flow path is associated with the port.

  • Patent number: 7541561
    Abstract: A process for heating powder materials by microwave radiation so that heating and sintering or melting progressively and directionally occurs within the powder materials. The process generally entails forming a structure from a powder by arranging the powder in a mass according to size of particles of the powder so that the particles are progressively arranged within at least a region of the mass from smallest to largest. The mass is then subjected to microwave radiation so that the particles within the mass progressively couple with the microwave radiation according to size, the smallest particles coupling first and heating faster than larger particles of the powder, and the largest particles coupling last and heating slower than smaller particles of the powder. As a result of the progressive arrangement of the particles, the mass is progressively and directionally heated by the microwave radiation.

  • Patent number: 7256377
    Abstract: An apparatus providing uniform microwave processing of products especially those that are likely to absorb microwave energy such as meat and the like. The apparatus uses at least a pair of complimentary processing waveguides. The waveguides are offset along at least one axis thereof so that the energy coupled to the product when traveling through a first waveguide section is presented with a complimentary or mirror image of the field variation applied to the product when traveling in the second waveguide. Energy may be fed to the elongated waveguides through a broad open wall or a wall having narrow openings. Coupling values can therefore be adjusted to transfer a higher percentage of energy in the feeder waveguide as microwaves propagate but then are diminished by a previous coupling section.

The inner housing includes an inlet port connected to an upstream water source and an outlet port connected to a downstream conduit. The casing and inner housing include generally spherical configurations. The inner housing is configured to induce a vortex of a water stream flowing between inlet and outlet ports. At least one magnetron is mounted to the casing for transmitting microwaves into the inner housing for heating the water stream at the vortex. A float valve in the inner housing allows the water stream to flow and be heated upon demand as the valve operates according to upstream and downstream pressure differentials.

  • Patent number: 7144471
    Abstract: A bonding method and apparatus for performing same in which a first member (e.g., a silicon chip) is bonded to a second member (e.g., a glass substrate such as a PCB) using a thermosetting resin adhesive. Near infrared rays are directed onto the second member, some of these passing through the second member to also heat the adhesive. A heater is pressed onto the first member and also heats the first member. Selective cooling is also utilized to assure an acceptable temperature gradient between both members and thereby prevent distortion of same which could harm the resulting structure.

  • Patent number: 7144739
    Abstract: A pressure-sealing, pressure-monitoring closure for non-invasively sealing a reaction vessel to a defined release pressure in microwave-assisted chemistry is disclosed. The closure includes a pressure-resistant, microwave-transparent reaction vessel, one portion of which defines a mouth, a flexible pressure-transmitting releasable cover assembly on the mouth of the vessel, a pressure transducer on the cover and external to the vessel for monitoring the pressure in the vessel as exerted against the flexible cover, and a clamp for urging the vessel, the cover and the transducer together under a defined force so that when the pressure in the vessel exceeds the defined force, the cover can flex and release the pressure from the vessel.

  • Patent number: 7030350
    Abstract: A microwave oven equipped with a toaster and a method of controlling the same. Particularly, the microwave oven equipped with the toaster is provided with a plurality of heaters and a plurality of buttons each corresponding to one or more heaters to selectively operate the heaters provided in the toaster, thereby minimizing a power consumption resulting from an unnecessary operation of the heaters. Further, the microwave oven equipped with the toaster and the method of controlling the same limits a consumption current by preventing the toaster and the magnetron from simultaneously operating, thereby being applicable to, for example, the wall mounted microwave oven having a limited consumption current.

  • Patent number: 7002121
    Abstract: A steam generator is located within a tank. At one end of the tank there is a flange. Mounted on the outside of the flange there is a magnetron that is cooled by a fan surrounding the magnetron. A heat tube extends from the magnetron into the tank. Within the heat tube there is a block of silicon carbide which has a passageway through it. The magnetron fires microwave energy down the passageway heating the block of silicon carbide and the heat tube. Water tubes about the inside surface of the tank spray a mist of water on the heat tube to produce steam which is removed by a steam line through ports at the opposite end of the tank from the magnetron. The steam may be used for many purposes but in a vehicle it may be injected into the cylinders of a four stroke internal combustion engine through the openings for the spark plugs. Make up water is collected from the dehumidifier. Water is recovered from the crankcase by a float system, and returned to the storage container.
