Abstract: A modified catalyst for polymerizing alpha-olefins, for example, ethylene, is prepared by combining a chromium compound-comprising catalyst, supported on a refractory oxide support with at least one catalyst modifier of the formula R Mg R′ where R and R′ are the same or different C₁-C₁₂ hydrocarbyl, alkoxy, alkenoxy or oxygenated aromatic groups. The amount of the modifier is such that the modified catalyst composition has the molar ratio of magnesium to chromium of 0.2 to 1.25. The modified catalyst composition produces resins of relatively high HLMI at relatively low temperatures. 
     There is also disclosed a process for polymerizing alpha-olefins, at relatively lower temperatures than was heretofore possible, to obtain resins of relatively high HLMI, using the modified catalyst composition. The resulting polymers can be used for the fabrication of blow-molded products, e.g., household and industrial containers.

Abstract: This invention relates to a process for preparing a supported metallocene alumoxane catalyst for use in the polymerization of olefins. The invention particularly relates to the use of silica gel containing from about 6 to about 20 per cent by weight adsorbed water as the catalyst support material. It has been found that such silica gel may be safely added to an trialkyl aluminum solution, preferably a mixed trimethylaluminum-­triethylaluminum solution, to form by direct reaction with the adsorbed water content of the silica gel catalyst support material the alumoxane component of the catalyst system. An alumoxane coated silica gel is formed to which a metallocene may be added and the resulting material dryed to free flowing powder. The dry free flowing powder may then be used as a supported metallocene alumoxane catalyst complex for gas phase or liquid phase polymerization of olefins.

Abstract: For the non-destructive determination of the internal ballistic characteristics of guns, an electromagnetic wave is injected via a waveguide transition (7, 7', 7") provided on the side of the barrel (1) and is extracted again after reflection on the round (6) located in the barrel (1). As a result of the arrangement of at least two injection openings (40, 40', 41) arranged in the longitudinal direction of the barrel (1) at a distance determined by the wavelength used, it is achieved that the injected wave runs virtually 100% in the direction towards the round (6) and that the extraction of the reflected wave also becomes more effective. In this way, the measurement signal for the respective round position, obtained from the change in phase between the injected and extracted wave when the position of the round in the barrel (1) changes is very large in comparison with interference signals so that significant measurements are possible even during live firing. …<IMAGE>…
