Title: System and method for remotely heating a polymeric material to a selected temperature
Inventor: CLARK WILLIAM GUY JR
IPC: B29C65/42
Filed: 1991-12-23
Granted: 2004-08-24
Abstract: Both a system and method are provided for remotely heating a polymeric material to a selected temperature.      The system generally comprises particulate ferro-magnetic material dispersed throughout the polymeric material to form a composite, wherein the particulate material has a Curie temperature that corresponds to the selected heating temperature, and a source of microwave energy for remotely applying a beam of microwave energy to the polymeric composite material.      Preferably, the particulate ferromagnetic material comprises only about 2 percent of the total composite by weight. The polymeric material may be compliant, thermosettable plastic, and the Curie temperature of the particulate ferromagnetic material dispersed therein may advantageously be above the curing temperature of the polymer, such that the beam from the source of microwave energy may be used to remotely join surfaces or construct joints in composite structures.      Alternatively, the polymeric material may be a meltable plastic, and the Curie temperature of the particulate ferromagnetic material may be chosen to be above the temperature of fusion of the polymer to create a polymeric composite which is magnetically separable from other polymers within a solid waste facility, and which may be melted down for recycling purposes. In a variation of this embodiment, a heat actuatable degradation chemical may be dispersed through the polymeric material along with the ferro-magnetic material to create a plastic composite which is selectively degradable by the remote application of microwave energy.

Title: Plasma treatment of polymer powders
Inventor: FOERCH RENATE
IPC: G03G9/087
Filed: 1993-12-21
Granted: 1998-01-20
Abstract: Surfaces of fine polystyrene (PS) and polymethyl methacrylate (PMMA) powders were modified by exposure to the downstream products of a nitrogen or oxygen microwave plasma. The effects of nitrogen and indium incorporation in the powder surface were studied with emphasis on variations in the triboelectric properties of the powder. X-ray photoelectron spectroscopy (XPS) was utilized to determine the changes in surface elemental composition. After nitrogen plasma treatment, the C 1s peak profiles suggested the formation of amines in the case of PS, and the formation of imines and amides in the case of PMMA. Oxygen plasma treatment suggested the formation of hydroxyl and carbonyl groups on the surfaces of both PS and PMMA. After treatment with a nitrogen or oxygen plasma, the charge-to-mass ratio (Q/M) of PS and PMMA powders in contact with carrier particles was measured using the cage blowoff method. The surface charge density (Q/A) was calculated from Q/M. The Q/A of nitrogen plasma-treated PS powder was seen to shift towards positive charge with small increases in the nitrogen concentration. The Q/A of oxygen plasma treated PS powder initially shifted toward negative charge, but changed towards positive charge with higher oxygen concentrations. Plasma-treated PMMA powder showed a different behaviour and the variation of Q/A on PMMA was much less than that of PS. Results suggest that triboelectrification of the polymer powder may be related to changes in the electrical surface states, and that nitrogen may act as a group V dopant within the PS surface.

Granted: 2003-10-14
Abstract: A process for injection molding arcuately-shaped hollow articles is disclosed. The process includes the steps of positioning a stack mold into an injection molding machine. The stack mold has first, second and third mold blocks with the first mold block positioned between the second and third mold blocks. Each of the mold blocks has a plurality of cavities formed therein. The cavities formed in the first mold block are designed to mate with the cavities formed in the second and third mold blocks when the stack mold is closed to form a plurality of arcuately-shaped cavities. The stack mold further contains a pair of slide carriers movably connected tr each of the second and third mold blocks and a plurality of inner cores secured to each of the slide carriers. The stack mold is closed by first moving both of the pairs of slide carriers such that each of the inner cores is positioned within one of the arcuately-shaped cavities to form a hollow interior in each of the molded articles.        The first and second mold blocks are then moved against the third mold block. Molten material is introduced into the arcuately-shaped cavities and is allowed to solidify. The stack mold is opened by moving the first and second movable blocks away from the third mold block and then moving both of the pairs of slide carriers outward to remove the inner cores from the arcuately-shaped cavities. The injection molded articles are then removed from the stack mold.
