A die-welding system for a de-icer assembly includes a die, a die base, a high energy source, and a de-icer assembly. The de-icer assembly includes a first welded-material layer and a second welded-material layer. At least one of the die and the die base includes a welded-portion pattern thereon configured to weld the first welded-material layer to the second welded-material layer in the pattern of the welded-portion pattern such that inflatable portions are formed within the welded-portion pattern formed in the de-icer assembly between non-welded sections of the first welded-material layer and the second welded-material layer.

A method of manufacturing a de-icer assembly includes positioning a first welded-material layer and a second welded-material layer between a die and a die base of a die-based welding system, wherein at least one of the die and the die base includes a welded-portion pattern configured to weld the first welded-material layer to the second welded-material layer in the pattern such that inflatable portions are formed within the welded-portion pattern formed in the de-icer assembly between non-welded sections of the first welded-material layer and the second welded-material layer, pressing the first welded-material layer and the second welded-material layer together between the die and die base, and applying high energy to the die-based welding system using a high energy source such that the first welded-material layer and the second welded-material layer are welded together at the areas in the shape of the welded-portion pattern to form a welded de-icer assembly.

A method of manufacturing an impeller for a thermal management device includes partially curing a curable liquid in a curable liquid bath to form a first stage rotor, removing the first stage rotor from the curable liquid bath, the first stage rotor having excess curable liquid on a surface thereof, rotating the first stage rotor to displace the excess curable liquid radially outward from a rotational axis to compensate for imbalances in the first stage rotor, and fully curing the first stage rotor and at least a portion of the excess curable liquid to produce a second stage rotor that is more rotationally balanced than the first stage rotor.

A method for welding a first hose end at a joint with a second hose end in a seam that extends on a circumference of the first hose end, the method comprising the steps: applying a protective layer at the joint to an inside of the first hose end; pushing the second hose end beyond the joint over the first hose end; pressing the first hose end and the second hose end together flat at the joint between two first damping jaws that are moved towards each other; welding the first hose end and the second hose end together by two first partial seams while pressed together, wherein the protective layer prevents a welding of the inside of the first hose end; releasing the first hose end and the second hose end from the two first clamping jaws after welding the two first partial seams.

There is described a method for forming a tube (3) of a web (4, 4) of packaging material comprising the steps of advancing the web (4) of packaging material along a web advancement path (P), overlapping a first lateral edge (19) of the web (4, 4′) of packaging material with a second lateral edge (20) of the web (4, 4) of packaging material for obtaining a longitudinal seam portion of the tube (3) and fusing at least an internal outer surface (34) of the first lateral edge (19) and an external outer surface (37) of the second lateral edge (20) with one another for longitudinally sealing the seam portion of the tube (3). The step of fusing comprises at least the substeps of directly heating the external outer surface (37) of the second lateral edge (20) and heating by contact the internal outer surface (34) by establishing contact between the internal outer surface (34) and the directly heated external outer surface (37).

Disclosed is a molded article including a modified fibroin and a water resistance-imparting material. The modified fibroin and the water resistance-imparting material may be covalently bonded.

A method comprising providing a polymeric substrate having a melting point of from about 130° C. to about 190° C., and locating a material layer onto the substrate, wherein the material layer comprises one or more polymeric materials that liquefy upon exposure to temperatures of at least about 100° C., to blend with a softened portion of the polymeric substrate. Upon exposure of one or more of the substrate and the material layer to a stimulus, the temperature is increased in a predetermined temperature zone of one or more of the substrate and material layer to cause blending of the one or more polymeric materials of the material layer with the softened portion of the polymeric substrate.

A method of making a window assembly having an electrically heated portion includes providing a glass pane having a major surface. An electrically conductive material is disposed over at least a portion of the major surface of the glass pane. One or more wire assemblies are attached to the electrically conductive material. A light curable potting material is disposed over the one or more wire assemblies. The potting material covers a portion of each of the one or more wire assemblies and adheres to a portion of the major surface of the glass pane. The light curable potting material flows over the one or more electrical wire assemblies and the major surface of the glass pane such that in 1 minute or less the light curable potting material has an outer surface that is in a parallel relationship with the major surface of the glass pane. Also, the light curable potting material is dimensionally stable in 5 minutes or less.

A method of manufacturing an impeller for a thermal management device includes partially curing a curable liquid in a curable liquid bath to form a first stage rotor, removing the first stage rotor from the curable liquid bath, the first stage rotor having excess curable liquid on a surface thereof, rotating the first stage rotor to displace the excess curable liquid radially outward from a rotational axis to compensate for imbalances in the first stage rotor, and fully curing the first stage rotor and at least a portion of the excess curable liquid to produce a second stage rotor that is more rotationally balanced than the first stage rotor.
