摘要： Methods and apparatus for rapidly drying and compacting wet fiber mats are disclosed. Rapid drying is produced by heating the wet fiber mats with a combination of radiowave energy and conductive heating. As the fiber mats are heated, three-dimensional compacting forces are applied by pressing the fiber mats between a flat surface press and a porous support on which is mounted a resilient mold insert. At high radio frequencies in the microwave range, power is transmitted from a multimode cavity through the porous support and resilient mold insert to the fiber mat. At low radio frequencies, differential radio-frequency voltages are applied directly to metal press plates which contain and compact the fiber mat. Methods and apparatus can be adapted to conveyorized or multi-opening press operations. Objects suitable for use with the invention are most commonly characterized by having a flat face surface on one side and webs or other features which may extend normal or generally normal to the flat surface.

摘要： A method and apparatus for applying microwaves to flowable materials within a centrifuge are disclosed. The simultaneous application of microwaves and centrifugation to flowable materials may be utilized to rapidly separate immiscible components from emulsions and dispersions. Microwaves are guided along a waveguide structure within the centrifuge. A meandering path for the waveguide is chosen through the interior of the centrifuge and through the flowable material being centrifuged. Gradual variation in the radial distance of the waveguide from the axis of the centrifuge produces a gradual filling of the cross-section of the waveguide along its length, forming a gentle microwave beach within the waveguide. Excellent microwave coupling and power deposition into the flowable material results. There is no need to contain the flowable material behind a dielectric barrier, normally placed between the incident microwaves and the flowable material, since confinement is provided by centrifugal forces. In its most general sense, the invention may be used to separate any variable-density flowable material, whether emulsified or not, or it may be used simply to rapidly heat a fluid without separation. Numerous applications exist in the petroleum, chemical, and food-processing industries.
摘要翻译：公开了一种将微波应用于离心机内的可流动材料的方法和装置。将微波同时施加和离心到可流动的材料中可用于将不混溶的组分与乳液和分散体快速分离。微波沿着离心机内的波导结构引导。通过离心机的内部并通过可离心流动的材料选择波导的曲折路径。波导从离心机的轴线的径向距离的逐渐变化产生波导沿其长度的横截面的逐渐填充，在波导内形成温和的微波海滩。优异的微波耦合和功率沉积成可流动材料。由于通过离心力限制，所以不需要将通常放置在入射的微波和可流动材料之间的电介质阻挡层后面的可流动材料。在其最普遍的意义上，本发明可以用于分离任何可变密度可流动材料，无论是否乳化，或者可以简单地用于快速加热流体而不分离。石油，化工和食品加工业存在许多应用。

摘要： A molded structural-wood-fiber product is disclosed that is formed in three dimensions under conditions of heat and pressure. The molded product has the form of a single-piece wood-fiber web consisting of corrugations having indentations along the ridges of the corrugations on both sides of the web. Sheet facings may be applied to one or both sides of the fiber web to form a stiff, lightweight composite panel that has similar stiffness both along and across the corrugations. Several fiber webs or composite panels may be bonded together in stacked configurations to produce high-strength, light-weight panels, beams or platforms for heavy-duty applications. The unique structure of the three-dimensional fiber web permits straightforward high-speed manufacture using a rigid mold and one-dimensional pressing forces. Specific items that can be manufactured utilizing the fiber web and composite panels include pallets, bulk bins, heavy-duty boxes, shipping containers, wall panels, roof panels, cement forms, partitions, poster displays, reels, furniture, caskets, and doors.
