  • Patent number: 6863859
    Abstract: The present invention relates to novel polymeric compositions that exhibit Reverse Thermal Gelation (RTG) properties for use as Support Materials (SM) in the manufacture of three-dimensional objects. These polymers are Temperature Sensitive Polymers that respond with a significant change of properties to a small change in temperature. Temperature Sensitive Polymers exhibit cloud point (CP) or lower critical solution temperature (LCST) in aqueous solutions. Water-soluble Temperature Sensitive Polymers are chosen to give low viscosity liquid at low temperature when dissolved in water and by that to permit easy dispensing at low temperature. Raising the temperature above their gelation temperature (Tgel) will result in solidification of the composition. At its gel position the material has favorable characteristics as a support and building material. The gel layers have the appropriate toughness and dimensional stability to support the model layers during the building process.

  • Patent number: 6803004
    Abstract: The present invention provides low cost resins (e.g., advanced epoxy resins), processes for making these resins, and coatings made with theses resins. Specifically, the present invention provides high throughput extrusion processing of advanced epoxy resins using an appropriate amount of an iminium salt catalyst. Preferred iminium salt catalysts are stable at room temperature in the reaction mixture (thereby enabling the pre-mixing of ingredients and the stable storage of the pre-mixed ingredients) and yet are highly efficient at the processing temperatures described herein. An example of one such advance epoxy resin is the reaction product of diglycidyl ether of bisphenol A with bisphenol A in the presence of an iminium salt catalyst. Preferred processes are performed using no solvent or only negligible amounts of solvent. One preferred extrusion process utilizes an intermeshing co-rotating twin-screw extruder, however, other types of extruders may alternatively be employed.

  • Patent number: 6752953
    Abstract: The present invention provides a method for manufacturing a non-gelatin hard capsule shell. The hard capsule shell is made by a heat-melting method which involves heating a capsule forming composition (preferably in powdery form) in a mold, followed by inserting a pestle into the mold to coat the melted capsule forming composition onto the pestle. The hard capsule shell thus formed, after hardened and dried, is removed from the pestle. This method has the advantages over the conventional “dip molding method” for not requiring the capsule forming composition to be pre-dissolved in solution so that no solvent is used in preparing the capsule forming composition. Also, by inserting a pestle into a mold, a pressure is imposed so as to ensure uniform coating of the capsule forming composition to the pestle. The present invention also provides a capsule forming composition which comprises a polymer and optionally a plasticizer and an apparatus for making the non-gelatin hard capsule shell.
