Abstract: A water deflection system is provided for use with a wall mounting assembly, wherein the water deflecting system and the wall mounting assembly are suitable for mounting to a wall of a structure, such as a building. The mounting plate and the cover plate of the wall mounting assembly are spaced apart from one another and/or provide sufficient clearance to allow for a downward flow of water therebetween. The water deflection system interrupts, channels, and/or directs this downward flow of water and safely diverts the water away from the region proximate to the top portion of the cut hole towards a region proximate to and/or below the bottom of the cut hole, thereby preventing the damage associated with water being introduced behind the siding.

If desired, the sensors can be formed of the same polymeric material as the bearing that is being examined. The sensors can provide real time dynamic contact information for joint members under conditions expected during use. In one particular embodiment, the sensors can be used to examine dynamic wear characteristics of artificial joint bearings such as artificial knee, hip, or shoulder bearings.

Abstract: A light olefin feed for an olefin utilization process is subjected to a water wash to remove water-soluble contaminants after which the water is separated from the olefin by coalescence separation at a low temperature, typically below 40° C. The coalescence separation technique is effective for separating the olefins from the water with its dissolved contaminants. If desired, a supplemental washing may be carried out by adding additional water to the feed/water mix after the initial wash step but before the coalescer in order to remove provide additional contaminant removal.
