    摘要： A method of continuously manufacturing a high viscosity polyalphaolefin product by introducing a monomer and an ionic liquid catalyst together into a reaction zone while simultaneously withdrawing from the reaction zone a reaction zone effluent that contains the high viscosity polyalphaolefin. The reaction zone is operated under reaction conditions suitable for producing the high viscosity polyalphaolefin product. The preferred high viscosity polyalphaolefin has a kinematic viscosity exceeding about 8 cSt and is the reaction product of the trimerization, oligomerization, or polymerization of an alpha olefin or a mixture of one or more product thereof. The high viscosity polyalphaolefins are useful as lubricants or lubricant additives.

    摘要： An apparatus for electrically insulating a pair of adjacent rail sections that form separate electrical signal circuits includes a pair of electrically insulating end posts positioned in a space provided between the adjacent rail sections. A metallic separator is disposed between the pair of electrically insulating end posts. Both the electrically insulating end posts and the metallic separator have a cross sectional configuration substantially the same as the cross sectional configuration of the adjacent rail sections. The adjacent rail sections are mechanically connected by a pair of connecting bars that are electrically insulated from and adhesively bonded to the adjacent rail sections. In another embodiment guard rail sections are insulated from each other by a pair of electrically insulating end posts positioned in a space provided between the individual guard rail sections. A metallic separator is disposed between the pair of electrically insulating end posts positioned in the space provided between the individual guard rail sections. Metallic spacers separate the adjacent rail sections from the adjacent guard rail sections. The adjacent rail sections and the adjacent guard rail sections are mechanically connected by a pair of connecting bars that are each electrically insulated from and adhesively bonded to the adjacent rails sections and adjacent guard rail sections.
