Secure inlays for secure documents such as a passport comprising an inlay substrate may have laser ablated recesses within which a chip module is installed. Channels for an antenna wire may be formed in a surface of the substrate. Instead of using wire, the channels may be filled with a flowable, conductive material. Patches homogenous with the substrate layer may be used to protect and seal the chip and interconnection area. The inlay substrate may include two layers, and the antenna wire may be between the two layers. A moisture-curing polyurethane hot melt adhesive may be used to laminate a cover layer and the additional inlay substrate layers. The adhesive layer may include metal nanoscale powder and ink for electromagnetic shielding. Additional security elements may include material that is optically changeable by an electromagnetic field. Ferrite-containing layers may be incorporated in the inlay substrate.

A device and method for applying dental composite matter to dental surfaces, such as cavities in teeth, gaps in teeth, or other deformations in tooth surfaces, or other applications to teeth, or appliances and devices used with teeth, such as crowns or inlays / onlays. A hand held powered tool provides oscillation of the composite material after the composite material is grossly applied to the dental surface. The oscillation is at a frequency and amplitude that facilitates uniform spreading of the composite material over the dental surface in a desired pattern, while retarding the tendency of the material to stick to the tool.

Hot-isostatic-pressure (HIP) is used to bond a cemented carbide inlay (e.g., an inlay ring) on a metal substrate (e.g., a hull ring). For example, an inlay ring is made from a powdered metal inlay preform typically comprising at least one metal carbide and at least one nonvolatile cement. The inlay preform is compressed and sintered to make an inlay ring having a predetermined shape, the inlay ring having a modulus of elasticity substantially greater than that of a hull ring. An inlay ring and a hull ring are sealingly vacuum brazed together with at least one evacuated bonding area between them. HIP is applied to compress the hull ring against the inlay ring, thus fusing the hull ring and inlay ring in at least one evacuated bonding area. Following HIP, the inlay ring and hull ring form a fused assembly in which the inlay ring substantially retains its predetermined shape.

Differential coefficients of thermal expansion facilitate close approximation during cooling of a sintered cemented carbide tubular inlay preform (e.g., a first tubular portion) which is vacuum brazed within a corresponding tubular metal hull (e.g., a second tubular portion). Such a tubular inlay preform comprises at least one metal carbide and at least one nonvolatile cement which have previously been compressed and sintered in a predetermined shape. The tubular inlay preform's modulus of elasticity and thermal conductivity substantially exceed the corresponding parameters of the tubular metal hull, whereas the hull's coefficient of thermal expansion exceeds that of the preform. Longitudinal movement of a tubular inlay preform within a tubular hull may be limited by structural features of the hull and / or preform. Additionally, circumferential compression of a tubular inlay preform due to hoop stress in a corresponding tubular metal hull increases as the hull cools after vacuum brazing.
