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.

Seat attachment for a stroller
Patent No. 8,955,869
The invention relates to a seat attachment for a stroller, single stroller and double strollers. Such a seat attachment may be used to reversibly convert a single stroller into a double stroller. More specifically, versions of the seat attachment relate to a seat attachment for a stroller capable of supporting a seat such as, but not limited to, a stroller seat, a baby seat, bassinet, a pram, a car seat, or a baby carrier, for example. The seat may be supported in front of a permanent seat of the stroller.

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.
