    Abstract: Ceramic implants, such as spinal implants, may comprise a dense shell and a porous core. In some implementations, methods for manufacturing the implants may comprise one or more stages at which the core material abuts the shell so as to form a mechanical attachment therewith while both the core and the shell are in a green state. The core and the shell may be fired together, and the resultant implant may, in some embodiments, comprise a unitary piece of ceramic material. Some embodiments may comprise silicon nitride ceramic materials.

  • Patent number: 8821772
    Abstract: A method comprising injection molding a plastic part from a polymer formulation comprising an injection moldable thermoplastic and a fluorescent compound, wherein the fluorescent compound has a decomposition temperature that establishes a maximum processing temperature for the polymer formulation. The fluorescent compound will thermally decompose to generate gaseous products causing visible bubble formation in the surface of the plastic part in response to exposure to a processing temperature that exceeds the decomposition temperature of the fluorescent compound. If the plastic part was processed without exposure to a processing temperature that exceeds the decomposition temperature of the fluorescent compound, then any fluorescent compound within the plastic part will cause the plastic part to fluoresce in response to exposure to black light. A suitable fluorescent compound may be, for example, selected from oxalates, carbamic acids, carbonic acids, diazocarbonyl compounds, and combinations thereof.

  • Publication number: 20140242313
    Abstract: A cavity between inner and outer walls of an open-box-shaped mould is filled with a polyurethane reaction mixture, containing an isocyanate and an emulsion of an isocyanate-reactive composition with three polyols and a blowing agent, which is cured to a polyurethane containing polymer. The inner and outer wall are a fixed distance from one another and each wall comprises a bottom and sides. The mixture is fed through an inlet in the bottom of the outer wall. Before filling the cavity, the mould is turned downwards so that the mixture foams upwards, filling the cavity. The three polyols are polyether polyol obtained by adding an epoxy to carbohydrates or difunctional or higher-functional alcohols; polyether polyol obtained by adding an epoxy to an aromatic amine; and polyester polyether polyol obtained by adding an epoxy to the esterification product of an aromatic dicarboxylic acid derivative and a difunctional or higher-functional alcohol.
