Copolymer fibers and processes for making same
Patent No. 8,957,183
The present invention concerns yarns comprising copolymer derived from the copolymerization of para-phenylenediamine, 5(6)-amino-2-(p-aminophenyl)benzimidazole; and terephthaloyl dichloride wherein the ratio of moles of 5(6)-amino-2-(p-aminophenyl)benzimidazole to the moles of para-phenylenediamine is 30/70 to 85/15; the yarn having a sulfur content greater than 0.1%; and the hydrolytic strength retention of the yarn is greater than 60%. The invention also concerns processes for making such yarns.

System and method for extending a lubricant discard interval
Patent No. 8,965,625
A system, a method and a computer program to predict a portion of used lubricant in an engine that is to be drained and replaced by fresh lubricant based on an analysis parameter value that is measured in a sample of used engine lubricant from the engine. The system includes a first input that receives the analysis parameter value from the used lubricant and stores the analysis parameter value in a memory of a processor. A second input receives an analysis parameter threshold value for the used lubricant at the end of a service interval and stores the analysis parameter threshold value in a memory of the processor. A determiner predicts a future analysis parameter value of the used lubricant at the end of the service interval based on the analysis parameter value, and the analysis parameter threshold value.

Friction modifiers for slideway applications
Patent No. 8,962,539
A slideway lubricating oil composition, additive concentrate, method of lubricating sliding parts. The lubricating oil includes a base oil; a metal-free friction modifier; and a metal-free, sulfur-free, phosphorus containing anti-wear/extreme pressure agent. The lubricating oil provides a lower coefficient of friction for non-metal sliding surfaces than for metal sliding surfaces.

Smoking article with tobacco beads
Patent No. 8,960,199
A component of a smoking article having tobacco beads. The tobacco beads can be located in a filter and/or a tobacco rod. The filter can be a multi-component filter, wherein an sorbent (preferably upstream) removes at least one constituent from mainstream tobacco smoke passing through the filter and downstream tobacco beads compensates for taste lost to the sorbent. The tobacco beads optionally include flavorants in addition to tobacco particulates. The tobacco beads can be located within a cavity in the filter or within the tow. This component can comprise additional flavors, which are released into the mainstream smoke under ambient conditions. The tobacco beads optionally include binders such as microcrystalline cellulose or other cellulosic material, which can be formed into a paste with tobacco powder and optionally with additional flavors. The paste can be extruded and spheronized to form the tobacco beads.

System and method for strengthening a sloped structure such as a berm, basin, levee, embankment, or the like
Patent No. 8,961,073
Embodiments of the invention comprise a system for strengthening a sloped structure such as a berm, basin, levee, or embankment. The comprises first and second opposing sides, the second side being adjacent the sloped structure; a bottom side adjoining bottom edges of the first and second sides, thereby forming a cavity within the first, second, and bottom sides; fill material disposed within the cavity; an impermeable membrane encapsulating at least a portion of the fill material; and a plurality of reinforcing members disposed within the fill material.
