  • Patent number: 10293568
    Abstract: A system and method for forming a vacuum bag packaging material into a desired shape includes subjecting the exterior of the packaging material to a vacuum to expand the packaging material. The expanded packaging material is then pressed into or against a forming device. Expanding the packaging material renders a filler material inside a sealed packaging membrane free flowing, such that the packaging material can assume the shape of the forming device during the pressing operation. When the vacuum is removed, the membrane recompresses upon the filler material and renders it non-free flowing such that the formed packaging material maintains the formed shape during ordinary handling.

  • Patent number: 8961716
    Abstract: An apparatus and method of uniformly heating, rheologically softening, and thermoplastically forming metallic glasses rapidly into a net shape using a rapid capacitor discharge forming (RCDF) tool are provided. The RCDF method utilizes the discharge of electrical energy stored in a capacitor to uniformly and rapidly heat a sample or charge of metallic glass alloy to a predetermined “process temperature” between the glass transition temperature of the amorphous material and the equilibrium melting point of the alloy in a time scale of several milliseconds or less. Once the sample is uniformly heated such that the entire sample block has a sufficiently low process viscosity it may be shaped into high quality amorphous bulk articles via any number of techniques including, for example, injection molding, dynamic forging, stamp forging, sheet forming, and blow molding in a time frame of less than 1 second.

  • Patent number: 8772674
    Abstract: When applying a current to a plated steel plate, plating often biases. In the present invention, when applying a current, the current is applied with a flux guiding member arranged in proximity to a side surface of the plated steel plate. The direction of the magnetic flux at the side surface of the plated steel plate is corrected, and the bias of the plating is efficiently suppressed.

  • Patent number: 8286367
    Abstract: A system for continuous (re-)drying of wood pieces. A conveyor arrangement receives and carries the wood pieces in file following a course. A moisture content of each wood piece travelling on the conveyor arrangement is measured during the course. The wood pieces whose measured moisture content are above a target content are diverted towards a drying equipment, in particular by high-frequency, whereas the other wood pieces continue their course on the conveyor arrangement. The drying equipment removes a moisture portion from the diverted wood pieces. The moisture contents of the processed wood pieces are again measured. The pieces whose moisture content dropped below the target content are routed towards the conveyor arrangement whereas the other pieces are routed in the drying equipment for a re-drying.

  • Patent number: 6184510
    Abstract: A cakeboard useful for direct transfer of a cake from the oven, for finishing and serving, without the need for a cooling rack. The cakeboard can have a first layer of corrugated cardboard and a second layer of PET. The first layer can have its top liner perforated with microperforations to permit venting of heat and moisture, thus allowing cakes to be turned from the oven directly onto the cakeboard to cool before finishing and serving, thereby removing the need for turning cakes onto separate cooling racks before transferring them to the cakeboard, thereby reducing handling. The microperforations can be added after the layers are affixed to each other such that the microperforations pierce the top second layer and the top liner of the first layer. The first and second layers can be comprised of other materials; and, other layers may be present.

  • Patent number: 5387782
    Abstract: The invention relates to an apparatus for the generation of smoothness in paper. The paper (1) is thereby supplied to the rolls (2) of the smoothing mechanism with a moisture distribution which is characterized in that the moisture content in the inner layers of the paper is substantially smaller or at least as large as in the outer layers. This can be achieved with the aid of a dielectric paper web heating device (3) which is positioned in front of the rolls (2) of the smoothing mechanism. Through the invention less energy is to be required for the same smoothness values and a lower reduction in volume is to take place.

  • Patent number: 5300749
    Abstract: The invention concerns a method and equipment for the compensation of voltage increase in electrodes of a apparatus used to process dielectric materials. In the apparatus the electrodes are arranged parallel, at a constant distance from each other across the conveying path of the material to be treated. Electric power to the electrodes is supplied by connecting the adjacent electrodes to a opposite pole of a high frequency power source. In order to minimize the voltage increase in the electrodes, a reverse magnetic field is brought to influence with the magnetic field of each electrode, by arranging a return path for the electrode current at a suitable distance from the electrode and connecting these return paths to the return paths of the adjacent electrodes.

  • Patent number: 5290490
    Abstract: A method and apparatus for thermoforming 3-dimensional articles of chosen wall thickness dimensions from a polar polymer sheet. The polymer sheet is dielectrically heated, the heating being controlled to impress a predetermined thermal pattern on the sheet. The thermal pattern is selected in accordance with the amount of stretching to which each area of the sheet is subjected during the subsequent work-forming step, the areas subjected to greater stretching being heated to a lower temperature and vice versa. Thus, the stretching action is balanced and results in accurate control of the wall thickness of the final article.
