A consumable filament for use in an extrusion-based additive manufacturing system, where the consumable filament comprises a core portion of a first thermoplastic material, and a shell portion of a second thermoplastic material that is compositionally different from the first thermoplastic material, where the consumable filament is configured to be melted and extruded to form roads of a plurality of solidified layers of a three-dimensional object, and where the roads at least partially retain cross-sectional profiles corresponding to the core portion and the shell portion of the consumable filament.

A molded packing material and a method of making the molded packing material. The molded packing material includes a plurality of molded fiber cushioning elements. The molded packing may also include a matrix comprising cellulosic fibers bonding the plurality of molded fiber cushioning elements to each other. The plurality of molded fiber cushioning elements and matrix form a mass that has been molded into a shape having exterior surfaces and an interior with some of the plurality of molded fiber cushioning elements being on the exterior surfaces of the mass and the remainder of the plurality of molded fiber cushioning elements being in the interior of the mass. The molded packing material may also include a fiber shell having a cavity formed therein with the plurality of molded fiber cushioning elements located in the cavity.

A composite material, which can be used as an encapsulant for an ultraviolet device, is provided. The composite material includes a matrix material and at least one filler material incorporated in the matrix material that are both at least partially transparent to ultraviolet radiation of a target wavelength. The filler material includes microparticles and/or nanoparticles and can have a thermal coefficient of expansion significantly smaller than a thermal coefficient of expansion of the matrix material for relevant atmospheric conditions. The relevant atmospheric conditions can include a temperature and a pressure present during each of: a curing and a cool down process for fabrication of a device package including the composite material and normal operation of the ultraviolet device within the device package.

One example includes a method for fabricating a compound material. The method includes providing a first discrete material layer having a first thickness dimension. The first discrete material layer includes a first material having a first magnetic susceptibility. The method also includes depositing a second discrete material layer having a second thickness dimension over the first discrete material layer. The second discrete material layer can include a second material having a second magnetic susceptibility. The relative first and second thickness dimensions can be selected to provide a desired magnetic susceptibility of the compound material.

A part of the sealed surface of the thermosetting resin member is a non-roughened surface that is not subjected to a roughening treatment. The other part of the sealed surface is a roughened surface recessed from the non-roughened surface to form a step and more roughened than the non-roughened surface. The thermoplastic resin member includes an additive added thereto, and the additive contains a functional group. A functional group existing in the roughened surface and the functional group existing in the additive are chemically bonded together. The roughened surface has a closed-circular shape that is formed over an entire circumference of the sealed surface around an axis parallel to the first direction. The three or more roughened surfaces each having a closed-circular shape on the sealed surface are arranged along the first direction with the non-roughened surface interposed as a distance between each adjacent two of the roughened surfaces.

Method for binding a bundle (5) of leaves (1) in a binding back (7), whereby the bundle (5) is placed in the binding back (7) with an edge (2) of the leaves (1) and fastened therein, characterised in that for the binding use is made of a bundle (5) of leaves (1) of which a strip (4) of each of the leaves (1) has been separately double folded beforehand along the same line to form a fold line (3) that extends parallel to and at a distance (A) from the aforementioned edge (2).

This disclosure generally relates to retroreflective articles and methods of making such articles.

An electrolysis prevention device, for preventing corrosion caused by electrolysis, includes a sacrificial anode made of an active metal and an anode holder supporting the sacrificial anode. The holder is adapted to fit around the inlet connection of an engine heat exchange component, such as a radiator or heater core, in such a way as to allow for a hose to be attached overtop the device. The device may be included in an originally-manufactured engine heat exchange component or may be installed later.
