  • Patent number: 10760271
    Abstract: This invention is an additively manufactured wall panel using computer aided design (CAD) and computer aided manufacturing (CAM) to design and manufacture multi-colored and multi-layered wall panels. This results in a variety of highly attractive, multi-colored wall panel faces ranging from brick, colored grout lines and multi-colored stones to multi-colored geometric designs. The design and manufacturing process greatly reduces the amount of precast cementitious materials by efficiently using higher quality materials. This reduces cost and weight while simultaneously producing a much more comprehensive, multi-functional wall panel complete with an interior frame, exterior insulation and an air, vapor and moisture barriers.

  • Patent number: 8741194
    Abstract: The invention relates to a method for producing a part using a deposition technique, especially a part in the form of a casting mold or a casting core. A layered composite is built up in layers, the individual layers each containing particulate material and binding material as well as optionally, a treatment agent. The layers maintain a predetermined porosity. The binding agent can be hardened especially with a fluid hardening agent. The layer composite is built up in the absence of the hardening agent. Once construction is complete, the layer composite is flooded with the fluid hardening agent using the residual porosity of the predetermined partial areas and in this way, is hardened.

  • Patent number: 8734609
    Abstract: A process for continuous manufacturing of moisture-curable polyurethane formulations used as sealants and adhesives. The process is characterized by the fact that the reactive components are introduced independently, and without the need for a prepolymer, to a mixer. Solid or liquid raw materials can be either pre-blended or fed directly to the mixer, a twin-screw extruder, which provides the requisite energy to homogenously mix the raw materials and drive the chemical reaction. The process is designed so that the extruder barrel and screw allow variable feed addition and heat exchange down the length of the machine. This allows various operations to be performed at different points in the extruder, including reaction, dispersive mixing, distributive mixing and devolitization.

  • Patent number: 8715558
    Abstract: A seamless microchannel with aligned microelectrodes structure can be prepared to include a polymeric body defining a surface of a seamless microchannel. The microchannel is seamless in that it is formed by a single body of material having a conduit that is open at one surface and extends to another opening aligned with microelectrodes in another surface of the body. The rest of the microchannel is closed and defined by the single body of material. The seamless microchannel structure can be used in methods that include biosensors, coupling waveguides, capillary electrophoresis chips, microreactors, polymerase chain reaction-chips, and solving mathematical problems.

  • Patent number: 8703030
    Abstract: A method for producing a high strength, flexible crosslinked polyethylene (PEX) material is provided wherein the base polymer is intermixed with a polymer modifier which affects the amorphous region of the polymer, leaving the crystalline portion of the base polymer virtually unaffected. Consequently, the amorphous region's density is lowered, resulting in a more flexible final product, while the crosslinked molecular structure and/or crystalline portion of the polymer, which controls the strength of the base polymer, remains strong. The polymer modifier can comprise a hydrocarbon fluid such as PAO, Group III basestocks, or a gas-to-liquid hydrocarbon. The plastic material has particular utility in the production of tubing, piping, and conduits for transporting gases, liquids, and the like, as well as wire and cable coatings such as jacketing and insulation.
