A load carrying structure having a selectively rigid or flexible characteristic includes a thermoplastic material (7) having a softening temperature above the operating temperature range of the load carrying structure, and a heating arrangement (8) provided to selectively heat the thermoplastic material to above its softening temperature. During normal operation, the thermoplastic material is in a rigid state and the overall load carrying structure is rigid to the prevailing loads. By activating the heating arrangement to heat the thermoplastic material to at least its softening temperature, the thermoplastic material and therewith the load carrying structure becomes flexible so that it may be deformed to a different configuration by applying a deforming load. Once the desired deformed configuration is achieved, the heating arrangement is deactivated, and the thermoplastic material is allowed to cool below its softening temperature so that it once again becomes rigid and rigidly fixes the new deformed configuration. The deforming force may be applied by any actuating mechanism, or for example by arranging shape memory alloys in connection with the thermoplastic material.

A hot-melt extruded composition having finely divided drug-containing particles dispersed within a polymeric and/or lipophyllic carrier matrix is provided. The carrier softens or melts during hot-melt extrusion but it does not dissolve the drug-containing particles during extrusion. As a result, a majority or at least 90% wt. of the drug-containing particles in the extrudate are deaggregated during extrusion into essentially primary crystalline and/or amorphous particles. PEO is a suitable carrier material for drugs insoluble in the solid state in this carrier. Various functional excipients can be included in the carrier system to stabilize the particle size and physical state of the drug substance in either a crystalline and/or amorphous state. The carrier system is comprised of at least one thermal binder, and may also contain various functional excipients, such as: super-disintegrants, antioxidants, surfactants, wetting agents, stabilizing agents, retardants, or similar functional excipients. A hydrophilic polymer, such as hydroxypropyl methylcellulose (HPMC E15), polyvinyl alcohol (PVA), or poloxamer, and/or a surfactant, such as sodium lauryl sulfate (SLS), can be included in the composition. A process for preparing the extrudate is conducted at a temperature approximating or above the softening or melting temperature of the matrix and below the point of solubilization of drug-containing particles in the carrier system, and below the recrystallization point in the case of amorphous fine drug particles.

Thin elongated bamboo chips are produced and then are softened and dried. The softening of the chips reduces void spaces which uses less glue and produces stronger members. The chips are then joined together with glue under pressure to form a bamboo board. By varying the depth and length of the chip form, the member produced can form a board, chipboard, beams, or columns of any size. Additional boards may be produced and glued together to form a larger board, beam, or column. Several chipboard layers fabricated in large sheets and glued together will form ‘multi-ply bamboo’, a bamboo substitute for plywood. Once cured, the member is kiln dried and sealed for moisture. The resulting bamboo member's strength and geometrical form is stable and consistent enough to be used as a structural grade member for frames, homes, buildings, and furniture.

A method for rapidly heating a mold cavity to a predetermined temperature preferably above the softening or melting temperature of the molding material prior to and during the molding stage thereby increasing moldability and improving quality of molded parts. The mold cavity is formed by two metallic halves on which high-frequency electric current is applied and an electric circuit involving the two halves is formed. Due to the proximity effect, the electrical current flows on the inner surfaces of the two cavity halves, thus rapidly heating the mold cavity. Proper use of insulation behind the cavity surface helps increase heating efficiency. Conformal on-off cooling channels provide both thermal insulation during the heating phase and rapidly cooling of the molded article during the cooling phase.
