  • Publication number: 20130196040
    Abstract: A method for cooking a product in an electromagnetic oven. In one embodiment product is conveyed to a convection oven. The product is then cooked to a moisture content of between about 3% and about 20%. The product is then conveyed to an electromagnetic oven where the moisture content is reduced to below 2.5%. The combination of the convection oven and the electromagnetic oven reduces the moisture gradient within the product which results in decreased post packaging stress cracks.

  • Publication number: 20130019491
    Abstract: An alignment film drying system and a method for drying alignment films are proposed. The alignment film drying system is used for drying an alignment film coated on a substrate. The alignment film drying system includes a plurality of magnetrons. The alignment liquid is coated on one side of the substrate facing the plurality of magnetrons and is heated through electromagnetic radiation produced by the plurality of magnetrons. The dried alignment liquid forms an alignment film having a uniform thickness, which ensures that the display effect of LCDs is better.

  • Patent number: 6751887
    Abstract: A system for dying material, in which system the material to be dried is located in a drying space isolated from its surroundings, in which space drying is done by way of negative pressure and a high-frequency electromagnetic field generated by electrodes. The drying space used is a drying batch-specific film package that is substantially separate from the rest of the equipment and that can be brought to an electromagnetic field generated by external electrodes. The film package serving as the drying space comprises nozzles, and for the period of drying, the package can be connected by tubes from the nozzles to equipment for removing moisture released from the material.

  • Patent number: 6344635
    Abstract: A method of firing ceramic materials involving placing the ceramic material in a microwave heating apparatus having a microwave cavity and subjecting the ceramic material to combination of microwave radiation and conventional heat energy according to predetermined time-temperature profile. The time-temperature profile, ranging from room temperature the sintering soak temperature, comprises a series of target heating rate temperature setpoints and a series of corresponding core and surface temperature setpoints with each of the core and surface temperature setpoints being offset from the target heating rate setpoints a predetermined offset temperature. In a preferred embodiment, the method involves continuously measuring the ceramic body core temperature, TC, and the surface temperature TS and independently controlling the microwave power and the conventional heat in response to the core temperature value and the surface temperature value, respectively.

  • Patent number: 6160578
    Abstract: Many improvements for a high speed camera including being able to process image data from a CCD array at one-quarter the pixel rate at which that image is provided by the CCD array; automatically demultiplexing color information in the digital domain; a high frequency, temperature compensated phase shift clock circuit to individually adjust the phase of the clock signal to each A/D converter; high frequency, high power analog, bipolar clock drivers to drive the horizontal functions of the CCD array since the necessary speed and power is not available in the horizontal driver section of commercially available CCD drivers; a technique to minimize the smearing of partial values of previous pixels into later pixels since the CCD array is being clocked faster than the internal time constant of the output stage of the CCD array; determination of, and compensation for, the dark reference (i.e.

  • Patent number: 5813133
    Abstract: Drying a coated substrate which includes magnetic particles includes a condensing surface spaced from the substrate. This creates a longitudinal gap between the substrate and the condensing surface. Liquid is evaporated from the substrate to create a vapor and the vapor is transported to the condensing surface without requiring applied convection. The vapor is condensed on the condensing surface to create a condensate which is removed from the condensing surface. Removal is performed, using more than gravity, without allowing non-uniformities of the condensate film to occur. The magnetic particles are oriented on the coated substrate by subjecting the coated substrate to a magnetic field created at a location outside of the dryer space.

  • Patent number: 5669156
    Abstract: An article separating and drying system which receives container ends from an infeed station, separates and dries the container ends and the compound applied thereto in a separating and drying station, and passes the articles to an outfeed station. The article separating and drying system includes a magnetic separating assembly which imposes a magnetic field on the container ends passing thereby for similarly magnetizing the container ends causing neighboring ends to repel one another. The magnetic repulsion of neighboring ends produces gaps between the neighboring ends as they move through the separating and drying station. A conveying device is provided to controllably move the container ends through the separating and drying station. An air distribution assembly is provided to deliver air to said separating and drying station and drive the air through the gap between neighboring container ends thereby contacting the liner compound applied to the container ends and removing moisture therefrom.
