摘要： A surgical implant including a cage having a first porosity and a first modulus; and a core bounded by said cage, said core having a second porosity that is higher than said first porosity of said cage, and said core having a second modulus that is lower than said first modulus of said cage. The implant may be functionally graded in a transverse direction, a longitudinal direction, or a radial direction thereof. The implant is made by preparing a first formulation for the cage within a first extruder and a second formulation for the core within a second extruder, extruding the first formulation through a co-extrusion die while simultaneously extruding said second formulation through the co-extrusion die so as to form an extrudate that includes said cage component and said core component bounded by said cage component.

摘要： This invention provides a system and method for forming a fibrous porous ceramic substrate that employs a screw extruder, and illustratively, a twin screw extruder to form a substrate by directing a homogeneous, wetted and mixed group of substrate components through a screw extruder die under pressure. The components of the mixture can be initially mixed in a substantially dry state by an appropriate mixer to form a homogeneous powder with a high dispersal of materials therein. The powder can be continuously mixed and conveyed to a feeder of the extruder. Along the path of the extruder, fluid can be introduced at a metered rate, along with other additives, such as colloidal silica (glass binder). The extruder's twin, co-rotating shafts include a combination of screw elements for feeding the mixture and shear-inducing mixing elements (kneading blocks) for thoroughly mixing fluid into the dry components. The wetted components pass through alternating sets of transport screws and kneading blocks until the kneaded, wetted mixture finally enter a vacuum section of the extruder where a vacuum is applied to remove excess air pockets and/or bubbles from the mixture. The mixture is thereafter driven through the die head where it exits as a continuous, extruded shape. Such a shape can comprise a honeycomb useful in filtration applications. The extruder can include a cooling system. The fifer in the mixture can be mullite. Alternatively the mixture can form a silicon carbide or other type of porous substrate matrix.

摘要： A system and method for mixing and forming gum structures is provided. The system may include combinations of continuous and batch mixers arranged generally in parallel and/or series for mixing gum base ingredients with subsequent gum ingredients. In one embodiment, the system and method first forms a gum structure that is not a gum base and then adds a subsequent gum ingredient such that the gum structure is less than a gum base in combination with a subsequent gum ingredient. In other embodiments, the system and method includes forming a gum base in addition to some subsequent gum ingredients that are not quite finished gum. Further, in other embodiments, the system and method may perform some of the mixing of the ingredients at a first location while mixing of further ingredients is performed at a remote location.

摘要： A method of making polymeric particulates wherein polymeric scrap material, virgin polymeric material and mixtures thereof are supplied to intermeshing extruder screws which are rotated to transport the polymeric material along their length and subject the polymeric material to solid state shear pulverization and in-situ polymer compatibilization, if two or more incompatible polymers are present. Uniform pulverized particulates are produced without addition of a compatibilizing agent. The pulverized particulates are directly melt processable (as powder feedstock) and surprisingly yield a substantially homogeneous light color product.
