Abstract: A process for rendering films, film composites, and articles made therefrom less resistant to passage of water vapor by passing a filled precursor film or film composite through the nip of interdigitating grooved rollers. The films or film composites are generally formed using a precursor film of a film forming polyolefin or polyolefin blend, with a relatively high filler loading and optionally an elastomer. A process is disclosed for making diapers or other disposable items where a relatively high water vapor is coupled with a resistance to liquid strikethrough.

Abstract: The method includes locating a target on a printed circuit board laminate having a circuit pattern etched thereon and utilizing the target to locate the laminate in a punching device. Preferably two such targets are employed and the laminate is adjusted in the X and Y directions as well as rotationally to bring the target into prescribed relationship with reference markings whereby to locate the holes precisely in the laminate whereby to facilitate stacking of the same. In related apparatus two television cameras are employed to operate with two targets to feed data into a microprocessor which generates signals to cause an alignment of the laminate to be punched. With respect to punching mechanisms special techniques are employed to locate the centers of the targets so that these centers can be aligned with cross hairs to take into account the deviations possible in the configurations of the targets.

Abstract: Lubricant formulations containing a combination, which has a synergistic action in respect of metal deactivation, composed of 1-[di-(2-ethylhexyl)-aminomethyl]-benztriazole which is methylated in the benzene ring in the 4-position and/or 5-position, and an antioxidant selected from a small group of antioxidants. Further additives can be added to these lubricant formulations. The compositions mentioned above reduce the abrasion phenomena in the components to be lubricated if they are added to mineral and synthetic lubricating oils, hydraulic fluids and lubricating greases.

Abstract: Films, made of polyethylenes and fillers, and articles made therefrom greater WVTR than previously available films based on conventional Ziegler-Natta based polyethylenes. The polyethylenes are produced in a metallocene-catalyzed production process. The films may be made by a cast film process, and may be made in widely varying filler content, generally polyethylene to filler ratios of 30/70 to 70/30. The metallocene based polyethylenes when combined with filler also permit the extrusion of thinner films leading to lighter weight and softer films. The m-polyethylenes utilized for making such films typically have a Composition Distribution Breadth Index above 50%, a Mw/Mn below 3, and a Mz/Mw below 2.
