  • Patent number: 7482390
    Abstract: A method of producing an open, porous structure having an outer surface defining a shape having a bulk volume and having interconnecting openings extending throughout said volume and opening through said surface, and products resulting from the method. The method comprises preparing a viscous mixture comprising a sinterable powder dispersed in a sol of a polymer in a primary solvent, replacing the primary solvent with a secondary liquid in which the polymer is insoluble to produce a gel comprising an open polymeric network having the sinterable powder arranged therein, removing the secondary liquid from the gel; removing the polymer network, and sintering the sinterable powder to form the open, porous structure. Also disclosed are shaped, porous products resulting from methods of the invention.

  • Patent number: 7018449
    Abstract: Particles may be used to filter oleo material such as grease from a flow of fluid such as a gas. The particles can be arranged into a bed to filter the oleo material from the fluid.

  • Patent number: 6868916
    Abstract: A fire sprinkler formed by an injection molding process is provided comprising a molded plastic body portion made of an injection molded plastic having a substantially hollow central portion for allowing water to pass therethrough, the hollow central portion extending from a distal end to a proximate end of the molded plastic body, a diffuser head portion located in the vicinity of the distal end of the hollow central portion, a sealing member made of an injection molded elastomeric material in proximity to the hollow central portion, and a link portion. When the link reaches a predetermined temperature the link portion is activated to start the flow of water out of the sprinkler.

  • Patent number: 6849186
    Abstract: Buoyant, sphere-like materials on the order of about 10 to about 300 microns and surrounded, at least in part, by (1) a variable blend of a ferromagnetic and paramagnetic material and (2) an absorbing or adsorbing material are effective vehicles for isolating targeted materials. By virtue of its relatively low density, the composite material is capable of remaining sufficiently suspended in solution for a suitable amount of time. In addition, the blend of ferromagnetic and paramagnetic materials allows for the isolation of a composite material from an environment such as a solution, yet discourages substantial self-attachment of the composite materials in solution, when subject to a magnetic field. Accordingly, multiple embodiments of composite materials having these and other properties are disclosed, as well as methods for making and using the same.

  • Patent number: 6814783
    Abstract: Inorganic, porous particles filter a substance or substances from a flow of fluid such as a gas. The particles can be arranged into a bed to filter a substance (filtrate substance) from a fluid. The filtrate substance can collect on or within the pores of the inorganic particles. Collection of the filtrate substance within the pores of the particles rather than within the interstices of the bed enhances the filtering capacity and does not impede the flow of fluid through the bed of particles. Furthermore, the inorganic particles are re-usable, in that they can be subjected to harsh filtrate-separation techniques, e.g., heat treatment, solvent extraction, detergent washing, and centrifugal separation, yet retain their desired properties.

  • Publication number: 20040139858
    Abstract: Inorganic, porous particles attract oleo material within a flow of fluid such as a liquid or gas. The particles can be arranged into a packed bed to filter the oleo material from the fluid flow, which can agglomerate in the pores of the filtering particles. Agglomeration of the filtrate within the pores of the particles does not impede the flow of fluid through the interstices of bed of particle and, hence, enhances the filtering capacity of the particles. Furthermore, the inorganic particles are re-usable, in that they can be subjected to harsh filtrate-separation techniques, e.g., heat treatment, solvent extraction and detergent washing, yet retain their desired properties. Methods of making and using these particles also are described herein. Inorganic, porous particles filter a substance or substances from a flow of fluid such as a gas. The particles can be arranged into a bed to filter a substance (filtrate substance) from a fluid.

  • Patent number: RE43116
    Abstract: Adherent packed beds of ceramic beads, each comprising a ceramic body coated with a biodegradable polymer, and fabric bags containing such beads in a packed, self-supporting configuration. The polymeric coating provides some resilience to a packed bed of the ceramic beads, and prevents the beads from moving with respect to each other when placed under stress, leading to reduced breakage. The ceramic beads desirably are osteoconductive, and preferably are formed of a ceramic material that is resorbed during bone growth, such as hydroxyapatite, tricalcium phosphate, or mixtures of these materials. The beads may contain, either internally or on their surfaces or both, a bone morphogenic protein, and the latter may also be included in the biodegradable polymer coatings on the beads.
