    摘要： This invention relates to the field of olefin polymerization catalyst compositions, and methods for the polymerization and copolymerization of olefins, including polymerization methods using a catalyst composition. One aspect of this invention is the formation and use of a catalyst composition comprising a stannoxy-substituted half-sandwich metallocene and an activator for olefin polymerization processes. For example, this invention encompasses the preparation of (η5-C5H5)Ti(OSnPh3)Cl2, its contact with an activator, for example, zinc-impregnated chlorided alumina, to form a catalyst composition, and the use of this catalyst composition for polymerizing olefins or acetylenes.

    摘要： A recoil brake isolation system for the hydraulic recoil brake cylinder of a large caliber gun, includes two sets of hydraulic valves disposed respectively within the inlet valve block and return valve block of the hydraulic cylinder, an orchestrated combination of which together block the flow of hydraulic fluid to or from the hydraulic cylinder during the recoil/counterrecoil cycle or upon failure of the hydraulic circuit. A method of hydraulically isolating a recoil brake cylinder of a large caliber gun for survivability and improved weapon performance and a gun incorporating such a system are also included.

    摘要： A target equipped with a reflector can be tracked in a measuring system including a laser tracker. The reflector is tracked by means of a tracking unit in a normal tracking mode and by means of a surveying device in an extraordinary tracking mode. A capturing unit having a detection range lying between the detection ranges of the tracking unit and of the surveying device is also present. If the target cannot be detected by the tracking unit but can be detected by the capturing unit, the orientation of the tracking unit is controlled according to a measurement by the capturing unit. If the target can then be detected by the tracking unit, a transition to the normal tracking mode is initiated. If the target can be detected only by the surveying device, the orientation of the tracking unit is controlled according to a measurement of the surveying device.
