Abstract: A base material for a lubricant mixture or a lubricant for use in the fifth wheel plate/king pin plate bearing area including polybutene, polybutylene and/or other similar elastomer and/or viscous non drying liquid, the combined mixture with a Saybolt Universal viscosity at 99.degree. C. using ASTM method D-2161, of greater than 500 SUS. In addition, the lubricant may include synthetic oil(s), mineral oil(s), natural oil(s), polyols and/or esters, in any combination, having a final, mixed or blended viscosity of between 2-60 measured in centistokes at 150.degree. C. using ASTM method D-445 and thermoplastic polymer(s) and/or wax(es) with a melting point of between 160.degree. F.-500.degree. F. The above combination of materials may constitute 60 percent or more by weight of the final lubricant mixture.

Abstract: A system for the transmission of power formed by a block that has a channel, groove or canal of some length, one or more keys that come in contact with the groove, guide, or with the walls of the channel and with the key or keys holding a shaft or quill in eccentric holes in the keys. The system serves to eliminate or compensate for vibration caused by bent shafts or quills as well as the noise and wear that these can produce.
