Thermoplastic starch compositions that include a particulate filler, e.g. an inorganic filler component, and optional fibrous component The compositions include a thermoplastic phase comprising a thermoplastic starch melt that contains, at a minimum, starch blended with an appropriate plasticizing agent under conditions in order for the starch to form a thermoplastic melt. The thermoplastic phase may also include one or more additional thermoplastic polymers and other optional reactants, liquids or cross-linking agents to improve the water-resistance, strength, and/or other mechanical properties of the thermoplastic melt, particularly upon solidification. The inorganic filler component may affect the mechanical properties but will mainly be added to reduce the cost of the thermoplastic starch compositions by displacing a significant portion of the more expensive starch or starch/polymer melt. Fibers may optionally be included in order to improve the mechanical properties of the thermoplastic starch compositions. The thermoplastic starch compositions may be shaped into a wide variety of useful articles, such as sheets, films, containers, and packaging materials. Because the thermoplastic starch compositions will typically include a thermoplastic phase that is biodegradable, and because the other components will either constitute a naturally occurring mineral and optionally a natural fiber, the overall composition will typically be more environmentally friendly compared to conventional thermoplastic materials.

An overmolding material is insert molded an over at least portions of the printed circuit board proximate to the LEDs to form a free standing high thermal conductivity material overmolding that covers at least portions of the printed circuit board proximate to the LEDs. The free standing high thermal conductivity material has a melting temperature greater than about 100° C. and has a thermal conductivity greater than or about 1 W/m·K. In some embodiments, the free standing high thermal conductivity material is a thermoplastic material.

A golf club having a hollow golf club head which is filled with a gas under pressure. The interior surface of the golf club head is coated with a solidified layer of plastic material. The pressurized gas permits the use of thinner face plates by compensating for forces generated when the face plate strikes a golf ball. The plastic layer is preferably applied through the process of rotational molding using a thermoplastic material.

Advanced Smart Cards and similar form factors (e.g. documents, tags) having high quality external surfaces of Polyvinylchloride (PVC), Polycarbonate (PC), synthetic paper or other suitable material can be made with highly sophisticated electronic components (e.g. Integrated Circuit chips, batteries, microprocessors, Light Emitting Diodes, Liquid Crystal Displays, polymer dome switches, and antennae), integrated in the bottom layer of the card structure, through use of injection molded thermosetting or thermoplastic material that becomes the core layer of said Advanced Smart Cards. A lamination finishing process can provide a high quality lower surface, and the encapsulation of the electronic components in the thermosetting or thermoplastic material provides protection from the lamination heat and pressure.

A bone implant (10) is implanted in a cavity parallel to an implant axis (I) and without substantial rotation. The implant includes, on an implant portion to be implanted, cutting edges (14), which do not extend in a common plane with the implant axis and are facing toward the distal end of the implant. The implant also includes surface ranges (16) of a material that is liquefiable by mechanical oscillations. The cutting edges (14) are dimensioned such that they are lodged in the cavity wall after implantation. For implantation, the implant is impinged with mechanical oscillations, resulting in the thermoplastic material being at least partially liquefied and pressed into unevennesses and pores of the cavity wall to form a form-fit and/or material-fit connection between implant (10) and cavity wall, when re-solidified. The cutting edges (14) anchor the implant in the cavity wall.

A joining pin (3.2) with which two parts (1 and 2) made from a porous material, particularly wood or a wood-like material, are to be joined together, is anchored in the porous material at predetermined anchoring points (31, 33). For this purpose, a bore (4.2) with a closed inner end (41) is made in the parts (1 and 2). The shape of this bore (4.2) is so matched to the joining pin (3.2) that it can be introduced substantially without force expenditure into the bore and is positionable in a first position. At least one predetermined anchoring point (31, 33) between the joining pin (3.2) and the wall of the bore (4.2) is formed when pressure is built up by pressing the joining pin (3.2) with a pressing force (F) more deeply into the bore to a second position. Energy is supplied in a planned manner to the joining pin (3.2) so that at the predetermined anchoring points (31, 33) the thermoplastic material of the joining pin (3.2) is plasticized. The locally plasticized plastic material is pressed by the local pressure into the porous material of the parts and forms local, macroscopic anchors (10, 20). The joining pin (3.2) is, e.g., made entirely from a thermoplastic material and the energy for plasticizing is supplied thereto by ultrasonic vibration.

A shaped body comprised of individual, interconnected layers may be produced from fibers in accordance with a solid freeform fabrication or rapid prototyping method. The fibers may be produced by extrusion molding a thermoplastic material.

A method and apparatus for making inexpensive, form-fitted, protective cases of thermal plastic or polycarbonate material that can be easily printed with decorative imagery and/or electronic circuitry for a variety of products, such as portable music players or radios, cell phones, lap-top computers, and the like. The method involves creating a tool having substantially the same surface dimensions of a product. An element is then molded from bulk film of thermoplastic material using the tool. Once the element is molded, it is trimmed from the bulk film. The resulting apparatus is a protective case intended to form-fit over the surface features and dimensions of the actual product used to define the tool.
