    Abstract: Zeolite-based hydrocracking catalysts having a low residual sodium content achieved by ammonium cation exchange are loaded with a hydrogenation agent comprising a mixture of a Group VIII non-noble metal and a Group VI-B metal by a process which avoids to a high degree loss of effective catalytic surface area. The use of an ammonium ion exchange medium having a pH value within critical limits for the second of two necessary cation exchange procedures is an essential feature of the process.

    Abstract: A method of cross-linking polyacrylamide is provided which is particularly suited to the fabrication of battery separators. To an aqueous solution of polyacrylamide is added a chromiumcontaining compound wherein chromium is present at a valence of other than +3 and a compound which will react with said chromium containing compound to yield chromium ions at a valence of +3 which initiate cross-linking of the polyacrylamide.

    Abstract: Process for the preparation of stable, high surface area, virtually pure zinc filaments and in particular zinc fibers and needles having a unique crystal structure consisting essentially of one or more single crystals preferentially orientated with an ''''a'''' axis parallel to the axis of the filament. The zinc fibers and needles are prepared by the electrolysis of a soluble zinc salt-containing electrolyte solution under conditions of extremely high cathode current density.
