    摘要: The invention relates to basic polynucleate aluminum hydroxy silicate sulfate compounds and to a process for their preparation. The process involves first mixing an alkali metal silicate and an alkali metal aluminate solution and optionally a third component under continuous stirring to form an alkaline intermediate mixture and slowly adding the resulting alkaline intermediate mixture to an acidic aluminum sulfate solution under high shear mixing conditions. Compared to processes of the prior art, the present invention leads directly to solution products having higher Al.sub.2 O.sub.3 concentrations. Moreover, the products prepared through this invention exhibit enhanced stability over time, and improved performance in flocculation-coagulation application.

    摘要: Flight control apparatus (10) for a cannon-launched anti-tank projectile. A boom that structurally secures four fins (18) and four nozzles (20) to an afterbody (12) of the projectile, and that provides for fluid communication from the afterbody to the nozzles, is provided in the form of an assembly (14) comprising intersecured tubes (22, 24, 26, 28) which define a longitudinal axis (30) of the assembly. The boom assembly (14) considerably reduces the weight and fabrication cost associated with a conventional boom which is provided in the form of an integral multi-channeled cylinder.
