Title: Method for removing volatile materials from a polymer composition
Inventor: KAWANO KOJI
IPC: C08F6/00
Filed: 1998-09-29
Abstract: There is disclosed a method for removing volatile materials, which comprises adding a blowing aid to a polymer composition containing volatile materials, mixing them in a static mixing apparatus, and extruding the resultant mixture by an extruding apparatus into a devolatilizing tank, thereby the mixture is made to be blown, to cause removal of volatile materials. First, the blowing aid (6) is discharged with an addition nozzle apparatus (2), in a direction opposite to the direction of the flow of the polymer composition (1), to be added, and the polymer composition is introduced into the static mixing apparatus (3), at a pressure at which the blowing does not take place, thereby mixing them. Then, using the extruding apparatus (11), the resultant mixture is extruded into the devolatilizing tank (4), so that the polymer is made into a blown product at such a temperature and a pressure that the blowing coefficient B given by the expression (1) becomes 1.4 or more, thereby causing removal of volatile materials:      Expression (1) B = A'/A wherein A represents the cross-sectional area of an extruding apparatus, and A' represents the average cross-sectional area of the polymer composition in a direction perpendicular to the vertical direction of the blown polymer composition, at a point where the polymer composition is dropped from the lower part of an opening section of the extruding apparatus vertically 50 cm to 1 m. The method can give a polymer composition having residual volatile materials in very small amounts, by removing volatile materials continuously with high efficiency.

Title: Stratifie pour interieur d'automobiles a revetement thermoplastique a faible brillance
Inventor: MERCIER DIANA M
IPC: B32B5/18
Filed: 1997-05-22
Abstract: L'invention porte sur un matériau pour revêtements intérieurs d'automobiles consistant en un film de peinture à couches opaques et transparentes (16, 20) à base de résine thermoplastique fixé à la surface extérieure d'une feuille substrat (22) semi-rigide de résine moulée par thermoplastie. Ledit film (16, 20) est de préférence obtenu par une technique de transfert de peinture sèche selon laquelle la couche transparente (16) et la couche à revêtement de base pigmenté (12) sont déposées sur un support de polyester puis séchées après quoi s'effectue une stratification du film (16, 20) par transfert du support vers la feuille substrat (22) à la surface de laquelle la couche transparente (16) constitue une couche protectrice extérieure à faible brillance. Le matériau constitutif de la couche transparente (16) est de préférence un mélange d'une résine acrylique et d'un fluoropolymère tel que le fluorure de polyvinylidène. La faible brillance de la couche transparente extérieure est due la dispersion d'une charge de particules fines telle que de la silice associée au fait que le film transparent extérieur est appliqué sur un support mat. Le thermoformage du stratifié composite visant à lui donner une forme tridimensionnelle confère à la surface de la couche transparente extérieure un niveau de brillance sous 60· extrêmement bas, de moins d'environ 15 unités et de préférence de moins d'environ 10 unités de brillance. Dans l'une des réalisations, le niveau de brillance tombe à moins de 2 unités de brillance.

Title: Method of surface oxidizing zirconium alloys and resulting product
Inventor: HINES GARY L
IPC: A61F2/44
Filed: 1998-03-27
Abstract: An oxide coating is formed on zirconium or zirconium alloys of refined microstructure by a process comprising at least the step of inducing an appropriate altered surface roughness such that subsequent oxidation results in a uniformly thick oxide coating. An oxide coating of uniform and controlled thickness is especially useful on orthopedic implants of zirconium or zirconium-based alloys to provide low friction, highly wear resistant surfaces on artificial joints, such as hip joints, knee joints, elbows, etc. The uniformly thick oxide coating of controlled depth on oxide coated prostheses provides a barrier against implant corrosion caused by ionization of the metal prosthesis.

Title: Improved plastic bottle closure
Inventor: BARTSCH ERIC RICHARD
IPC: B65D41/48
Filed: 1998-04-14
Abstract: This invention relates to an improved design for the tear handle of a tamper evident closure. Specifically, the invention relates to a design for a closure tear handle (28) which prevents damage to the closure tear skirt (24) under large application forces when the closure is applied to the bottle; this invention also provides a tear skirt which is easier for consumers to remove.  A weak region (46) is placed at the base (38) of the intersection of the tear handle (28) and the wall of the tear skirt. This weak region (46) of the closure is designed such that upon contact with the neck finish of a bottle, which puts the tear skirt into tension, it attracts the tensile forces and relieves stress from the adjacent weak point (42) of the closure tear skirt to prevent damage to this area that would be offensive to consumers and result in wasted product.
