    摘要： A friction welding apparatus for preparing weldments by fictional contact of the weld members which includes sensors for measuring torque, axial forces, and other variables important to the control of the welding process, and for facilitating the obtainment of process information useful in correlating process conditions with weld quality. The apparatus includes means for the substantially frictionless coupling of the component providing the axial normal force on the aligned shafts upon which the weld pieces are mounted. The coupling, which contributes to accurate torque measurements, comprises a substantially frictionless, single-contact-point coupling provided by the point of contact between two adjacent spherical surfaces. The welding apparatus is also provided with a vacuum-braked air drive assembly for substantially instantaneously stopping relative rotation between the weld members after fusion of the members has occurred, thereby preventing undesirable over-run and resulting stress formation in the weld zone.

    摘要： In various embodiments the invention is directed to a structured filament for use in fused filament fabrication comprising an inner core comprising an first polymer or polymer blend; and an outer shell surrounding said inner core comprising a second polymer or polymer blend having ionic or crystalline functionality; wherein said first polymer or polymer blend has a higher solidification temperature than said second polymer or polymer blend. The ionic or crystalline functionality of the outer shell material strengthen the interface between the printed layers. This structured filament leads to printed 3D structures having improved dimensional fidelity and impact resistance in comparison to the individual components. The impact resistance of structures printed from these is greatly increased as energy is dissipated by delamination of the shell from the core near the crack tip, while the core remains intact to provide stability to the part after impact.

    摘要： A method of preparing a polymer film having an oriented dispersed material includes casting a multi-layer polymer solution having a first polymer solution layer and a second polymer solution layer where the second polymer solution layer is at least partially immiscible with the first polymer solution layer. The method further includes passing the multi-layer polymer solution through an electric field application zone, to thereby induce orientation of the dispersed material. A multi-layer polymer film can then be formed by drying the solvent from the multi-layer polymer solution. An apparatus for preparing polymer films includes a top electrode made from a flexible metal mesh coated with a non-stick, non-conductive coating.

    摘要： The present invention generally relates to implantable devices for producing insulin in diabetic animals and to methods of making same. Some embodiments include amphiphilic biomembranes for use in biological applications (e.g., as an alternative and/or supplemental insulin source). Some embodiments also include live insulin-producing cells contained within one or more amphiphilic membranes so as to prevent or diminish an immuno-response and/or rejection by the host.
