A method and apparatus for removing a SMP apparatus from within a cured composite part. The method may comprise the steps of triggering the SMP apparatus from a rigid state to a malleable state, inducing a pressure differential that drives the SMP apparatus, in the malleable state, away from the cured composite part and toward an inner mandrel tool, and removing the inner mandrel tool with the SMP apparatus resting thereon out of the cured composite part. The inner mandrel tool may comprise an outer surface having varying contours such that a surface area of the outer surface is great enough to prevent the SMP apparatus from folding over onto itself or creasing when driven toward the inner mandrel tool. A maximum straight line distance between points on the outer surface may be small enough to allow the inner mandrel tool clearance for removal from the cured composite part.

The present invention provides surgical training aids formed from hydrogels and adapted to exhibit realistic mechanical properties mimicking those of real organs. Surgical training aids are preferably fabricated by subjecting a concentration of polyvinyl alcohol to freeze-thaw cycles in a mold designed to approximate the shape of an organ, and process parameters are selected to tailor the mechanical properties of the formed hydrogel to those of the organ simulated by the surgical aid. The mechanical properties of the hydrogel forming the surgical training aid may be tailored by incorporating bacterial cellulose and by applying strain during hydrogel formation, thereby producing controlled anisotropy.

Cast Molded Parts Formed from a Liquid Crystalline Polymer

Номер: US20130062558A1
Автор: Gray Steven D., Grenci Joseph J., Nair Kamlesh P.
Принадлежит: Ticona LLC

A molded part having a predetermined shape is provided. The molded part may be formed by casting a liquid crystalline polymer composition into a mold cavity at a relatively low shear rate. Due to the use of a relatively low shear rate, the polymer composition does not generally undergo extensive shear orientation, which can allow the resulting part to be further processed using standard finishing techniques. The ability to use relatively low shear rates during casting is achieved in the present invention through the use of an aromatic amide oligomer. More particularly, the present inventors have discovered that the aromatic amide oligomer can serve as a flow aid by altering intermolecular polymer chain interactions, thereby lowering the overall viscosity of the polymer matrix to “ultralow” levels without having a significant impact on the mechanical properties. 1. A molded part that is formed by casting a polymer composition into a mold cavity , wherein the polymer composition comprises a thermotropic liquid crystalline polymer and an aromatic amide oligomer , and wherein the polymer composition has a melt viscosity of from about 0.1 to about 80 Pa-s , as determined at a shear rate of 1000 secondsand temperature of 350° C. in accordance with ISO Test No. 11443.2.

The acupressure element includes a base with spiked applicators and an additional layer of low-melting substance, which creates a surface flush with the points of the spiked applicators. The layer hides the points and prevents pain. During a reflexotherapy procedure, the layer of low-melting material melts, either under the influence of human body heat or with the use of external heating. The points of the spiked applicators are gradually released and begin to press on the skin. The pressure on the skin does not occur immediately, allowing to prepare for increased pain later and acclimate accordingly.
