    摘要: A navigation system is disclosed for providing navigational directions. It has a navigation device with a body provided with a receiving part. The receiving part has an inner surface provided with a connecting element of a first connection type. The navigation system further includes a docking system arranged to accommodate the navigation device. The docking system has an extending part provided with a connecting element of a second connection type. The connecting element of the second connection type is arranged for connection to the connecting element of the first connection type. The extending part further includes an outer surface with a shape similar to the inner surface of the receiving part of the navigation device. In at least one embodiment, the receiving part is slideable along a trajectory over the outer surface, the trajectory being determined by the shape of both the inner surface of the receiving part of the navigation device and the outer surface of the extending part of the docking system. Particularly, the trajectory is such that the connecting element of the first connection type is guided towards the connecting element of the second connection type for connection.

    摘要: A hydrocarbon oligomer and a process for its production is disclosed that is useful as a pour point depressant and as a combination pour point depressant and viscosity index improver for mineral oil or synthetic oil. The oligomer is also useful in modifying wax crystal formation at low temperature when added to distillate fuels. The oligomer is a near linear copolymer of a mixture of ethylene and C.sub.3 -C.sub.28 1-alkenes, or only 1-alkenes, wherein a large proportion of the pendant alkyl groups of the recurring 1-alkene monomer units contain between 14 and 22 carbon atoms. The oligomer is produced by polymerization of mixed 1-alkenes with reduced chromium oxide catalyst on silica support.

    摘要: A method and apparatus for measuring thickness and traction properties of elastohydrodynamic lubricant (EHL) films is described. The apparatus utilizes at least one ball or roller loaded against the internal diameter of a transparent ring having a larger radius than said ball or roller. A lubricant is placed between the rotating roller and ring thereby forming an EHL film where the ball and ring contact. Roller and ring rotating speeds are controlled to obtain different amounts of relative sliding motion between their surfaces. Contact between the surfaces and the resultant film are observed via the transparent ring which allows optical measurements of lubricating film thickness. Traction forces generated during contact are measured by any suitable force measuring device.
