Abstract: The present invention relates to a method for molding a product and the molds used therein, wherein said method comprises the steps of heating a surface layer (16) of a mold cavity via induction heating to the temperature of 50-400 C for 0.5-20 sec, filling of molding material into the cavity and cooling the mold by circulating a cooling fluid through a cooling line, wherein the mold comprises a surface layer (16) and an insulating layer (17) in which micro-channels (15) or micro-holes (18) are constructed.

Abstract: Disclosed is a unidirectional fiber sheet comprising an arranged fiber layer, a multi axial scrim, and a release paper having 3 to 80% of its surface area coated with an adhesive. The adhesive is applied to the release paper in the form of stripes which may be positioned parallel, perpendicular or oblique to the filaments of the arranged fiber layer. The unidirectional fiber sheet according to the present invention is prepared by partially coating a release paper with an adhesive, and heat-pressing together an arranged fiber layer prepared from filament tows, a multi axial scrim having a net structure to support the arranged fiber layer, and the release paper so as to bind the three together.

Abstract: A plate type heat transfer device which has a number of rectangular or oval cavities (or cell) in its transverse cross-section, is charged with a certain amount of a working fluid in each of the cavities (or cells). Heat from the lower surface of the plate is transferred to the upper surface of the heat transfer device. The device has a wide range of application, such as for the stabilization or protection of foundation for pipelines roads, airport runways, structures, etc., by keeping the foundation intact in extremely cold regions, or to the ceilings or floors of relatively large spaces, such as office buildings, manufacturing factories, storage buildings, or even to the roofs of refrigerator cars where the temperature control is required.
