    摘要： A method and apparatus for rapid heating of calender rolls 350, 352 for a calendering apparatus 200 is disclosed. At a heating area 800, the rolls 350, 352 are preheated, reheated, or maintained at any temperature prior to the rolls 350, 352 being placed into the calendering apparatus 300. The preferred method of heating is by induction heating. The rolls 350, 352 may be delivered to the heating apparatus 802 from an initial storage area 420 or the calendering apparatus 300. The rolls 350, 352 are transported by an overhead transfer mechanism 400. The disclosed method and apparatus greatly facilitate formation of multi-layered laminates and is particularly useful in the tire building art.

    摘要： A hydraulic sample mounting press utilizes a face seal against the top face of a molding cylinder. The face seal employs a hydraulic cylinder to press a disk-shaped surface of a cap piece against the top annular face of the mold cylinder for a metallographic mounting press. The face seal cylinder is mounted to a hydraulic fluid column that allows the face seal to rotate away from the mold cylinder for access to the molding cylinder and to rotate into place when a metallographic mount is to be molded.

    摘要： A novel dielectric heater including a RF source having a first impedance, a parallel plate mold having a second impedance, and an impedance network, matching the first impedance to the second impedance, connected to the RF source and the parallel plate mold. The impedance network may be connected in series with the RF source and the parallel plate mold. The RF source may include a RF terminal and a common terminal, the impedance network may include a first terminal, connected to the RF terminal, and a second terminal, and the parallel plate mold may include a first plate, connected to the second terminal of the impedance network, and a second plate, connected to the common terminal of the RF source. In an alternative embodiment the novel dielectric heater includes parallel plates divided into a number of series-connected cells. The series cells lower the capacitive component, and may be configured such that an impedance of the parallel plate mold approximates an impedance of the RF source.

    摘要： Panel construction for forming upholstery panels for use in automotive vehicles and the like, where a plastic substrate which has been formed to a desired configuration, is placed over a grounded metal horn, a layer of adhesive fabric is placed over the substrate, a layer of heat bondable foam is placed over the adhesive fabric, a cover layer is placed over the foam, heat seal punches connected to the positive output of a source of electrical energy are selectively brought in horizontally on all sides of the panel perimeter to successively compress the cover and foam against the sides of the substrate. Electrical energy is applied to the heat seal punches when in selective engaged position to melt the adhesive and the foam, and fasten the cover to the substrate. The punches are withdrawn and the completed panel is removed from the horn.

    摘要： A thin film electric heater employs voltage and current suppressed below values of an allowable voltage and an allowable current. The thin film electric heater includes a thin film electric resistor to be formed directly on a surface of an object to be heated and is energized to effect heating. The resistor has a surface resistivity r, expressed by r=.rho./t (where .rho. is the volume resistivity of the thin film electric resistor and t is the film thickness of the thin film electric resistor), within a range to achieve the heating function of the thin film electric heater while the values of voltage and current applied to the thin film electric heater are suppressed below the values of the allowable voltage and the allowable current.
