Patent number: 6368544Abstract: All of the current processes for making molded particleboard products require very long furnish dwell times within a heated press, due to the low heat transfer rates from the heated molds to the furnish being compressed. Furnish dwell times vary between approximately one minute to more than 10 minutes, depending upon the part thickness. Since profitability of a particleboard molding operation is closely related to product throughput, these long furnish dwell times within the heated press limit production rates and continue to be a major economic concern to the industry. The essence of the invention is a heretofore unsuggested use of radiowave energy to speed production of molded particleboard parts by preheating the furnish prior to the application of heat and pressure within the forming mold. Because radiowaves propagate readily throughout the volume of the furnish, rapid heating is obtainable even for a loose, uncompacted particulate furnish that has very poor thermal conductivity.Type: GrantFiled: November 5, 1999Date of Patent: April 9, 2002Inventor: Thomas L.

Patent number: 5866060Abstract: The method and apparatus for making a preform which is a rigid shaped item formed of glass fibers rigidly joined to each other where adjacent fibers touch. The interstices between the fibers are unfilled for the use of matrix resin to subsequently form a molded article. The preform is formed by shaping fibers into the preform shape, applying a binder to the fibers so that they are coated at the locations where they touch. The binder is sensitive or responds to the application of electromagnetic energy. In completing the preform after the application of the binder, the preform is subjected to electromagnetic energy so that the binder hardens to form a rigid preform. In one species form, the electromagnetic energy is applied in the form of microwave energy. The application of electromagnetic energy causes a reaction in the binder without requiring heating of the glass fibers so that the preforms can be rigidified rapidly and efficiently.Type: GrantFiled: March 10, 1995Date of Patent: February 2, 1999Assignee: C.

The method and apparatus uses a metal mold (10, 212) with a cavity (401) for the molding as well as for confinement of the electromagnetic waves. Multiple low loss ports (A, B, C, D, E, p1, p2, p3) are provided for introducing the microwaves into the cavity.Type: GrantFiled: July 3, 1996Date of Patent: June 23, 1998Assignee: Board of Trustees operating Michigan State UniversityInventors: Martin C. Hawley, Jes Asmussen, Jr., Jianghua Wei, Trent A. Shidaker

Patent number: 5663893Abstract: A method for synthesizing correction features for an entire mask pattern that initially divides mask pattern data into tiles of data--each tile representing an overlapping section of the original mask pattern. Each of the tiles of data is sequentially processed through correction feature synthesis phases--each phase synthesizing a different type of correction feature. All of the correction features are synthesized for a given tile before synthesizing the correction features for the next tile. Each correction feature synthesis phase formats the data stored in the tile into a representation that provides information needed to synthesize the correction feature for the given phase. Methods for implementing edge bar and serif correction features synthesis phases are also described.Type: GrantFiled: May 3, 1995Date of Patent: September 2, 1997Assignee: MicroUnity Systems Engineering, Inc.Inventors: Kurt E. Wampler, Thomas L. Laidig

Patent number: 5648038Abstract: Systems and methods for monitoring workpiece and workpiece material characteristics using microwave energy are disclosed. A system includes a chamber, including means for generating variable frequency microwave energy; means for positioning a workpiece within the chamber; means for subjecting the workpiece to a plurality of different microwave frequencies; and means for monitoring characteristics of the workpiece. One or more characteristics of a workpiece, or workpiece material, may be monitored by positioning the workpiece within a chamber having means for generating variable frequency microwave energy; subjecting the workpiece to microwave irradiation at a plurality of frequencies; detecting power reflection for each one of the plurality of microwave frequencies to provide power reflection data; and comparing the power reflection data to a predetermined set of power reflection data.Type: GrantFiled: September 20, 1995Date of Patent: July 15, 1997Assignee: Lambda TechnologiesInventors: Zakaryae Fathi, Richard S. Garard, Jianghua Wei, Michael L. Hampton

Patent number: 5639414Abstract: A method of manufacturing pneumatic vehicle tires, the tires having a carcass which extends between two bead rings and a breaker arranged between the carcass and a tread, wherein the respective tire blank is built up using exclusively non-metallic components, and wherein, in the course of vulcanization and shaping which takes place under the action of heat and pressure, at least a part of the thermal energy that is required is introduced into the tire in the form of microwave energy. In order to improve the tire quality and in particular to avoid defects as a result of incorrect thermal treatment, the temperature which prevails in the tire is controlled in different tire regions in dependence on the temperature development and differently for different tire regions.Type: GrantFiled: June 5, 1995Date of Patent: June 17, 1997Assignee: SP Reifenwerke GmbHInventor: Klaus Unseld
