    摘要： An integrated evaluation and simulation system for ground combat vehicles interactively evaluates concept design decisions and design requirements in the context of an operational ground combat vehicle. The combat effectiveness of a ground combat vehicle may also be concurrently tested by virtual simulation. A computer system is programmed to implement a causal network model comprising an integrated collection of analysis models for creating a virtual representation of a ground combat vehicle. The integrated evaluation and simulation system includes a user interface operatively coupled to at least the computer system to selectively input data into the causal network model and receive information therefrom, and at least one virtual simulation system. The system can further include either a virtual simulation system operatively coupled to the causal network model or, as part of the computer system, a virtual simulation system interface to communicate with a separate virtual simulation system.

    摘要： A fiber optic splice and fiber holder and a housing for one or more of such holders. Each holder includes spool-type apparatus for removing slack in two fibers joined by a splice. Each housing accommodates a plurality of such holders, each of which is readily inserted into and removed from the housing.

    摘要： Ammonium zeolites of extremely low alkali metal content are prepared by a process of potassium ion exchange followed by ammonium ion exchange. Zeolite X or zeolite Y that contain a significant amount of sodium are contacted with a potassium salt solution under conditions that provide a substantial exchange of potassium for sodium. The potassium enriched zeolite is then contacted with an ammonium salt solution so that the ammonium ion replaces the sodium and potassium ions. The resulting ammonium zeolite X or Y contains considerably less than 1% alkali metal calculated as Na.sub.2 O.
