Abstract: An additive layer manufacturing method, preferably using selective laser sintering, for manufacturing a solid article, the method including applying a layer of a powder, the powder including at least one powdered (co)polymer, onto a solid substrate in a processing chamber; fusing the powder layer onto the solid substrate; subsequently depositing successive layers of the powder, wherein each successive layer is selectively fused prior to deposition of the subsequent layer of powder so as to form the article. In some embodiments, the powder further includes abrasive particles having a hardness greater than or equal to that of aluminum oxide.

Abstract: Metal bond abrasive articles and methods of making metal bond abrasive articles via a focused beam are disclosed. In an aspect, a metal bond abrasive article includes a metallic binder material having abrasive particles retained therein, where the abrasive particles have at least one coating disposed thereon. The coating includes a metal, a metal oxide, a metal carbide, a metal nitride, a metalloid, or combinations thereof, and the at least one coating has an average thickness of 0.5 micrometers or greater. The metal bond abrasive article includes a number of layers directly bonded to each other. Metal bond abrasive articles prepared by the method can include abrasive articles having arcuate or tortuous cooling channels, abrasive segments, abrasive wheels, and rotary dental tools.

Abstract: Mat (1) for mounting a pollution control element in a housing, comprising inorganic fibre material. At an edge surface (20) of the mat a plurality of fibres (30) are heat fused to form fusion volumes (90). The average number of fusion volumes per square millimetre of the edge surface is at least 100, and at least 80% of the fusion volumes have a projected size of between 10 ?m and 100 ?m.

Abstract: The present invention relates to printed hook components for hook and loop mechanical fasteners, and other components such as on diaper chassis and other personal hygiene articles, and methods for making the same. The hook component comprises an organic polymer, a laser-sensitive agent, and a laser-induced print on the hook component created by the interaction of electromagnetic radiation with the laser-sensitive agent. The hook component can be used in a variety of applications, including mechanical fastening devices for personal hygiene articles such as diapers, adult incontinence pads, and medical gowns.

Abstract: The present disclosure describes a flat lightguide configured to be illuminated by one or more small light sources, such as light emitting diode (LED) light sources. The one or more small light sources inject light into an end of a stepped lightguide that includes light redirecting elements capable of changing the direction of the light to exit perpendicular to the stepped lightguide and enter an edge of a planar lightguide.

Abstract: The present invention provides in one aspect a light device having a light guide. The light guide (20) has at least one major side defining a light extraction side (26). The light device further has at least one fibrous layer (30), typically a non-woven or woven fibrous layer, disposed on the major side of said light guide defining said light extraction side. At the light extraction side, the light device has a plurality of discrete bonding areas (40) at which the at least one fibrous layer is bonded to the major side of said light guide. In a particular aspect, the bonding areas define light extraction elements on the light extraction side. Such an arrangement typically provides for an easy, reliable and cost-effective light device useful for a variety of applications including, for example, illuminating the interior of a vehicle.
