Abstract: The invention relates to a blocking film, in particular hot blocking film, consisting of a carrier film and a transfer layer which can be removed therefrom and which has at least one magnetic layer of a dispersion of magnetisable particles based on chromium dioxide and/or iron oxide, and which may carry, on the side facing away from the carrier film, an adhesive layer which serves for fixing the transfer layer to a substrate.

Abstract: The novel feature in prodn. of acetylene and synthesis gas by partial oxidn. of hydrocarbons with O2 where the starting gases are separately pre-heated, intensively mixed, reacted during passage through a burner block and finally rapidly cooled is that the through channels (6) in the burner block have their inlets covered by perforated (13) discs (14). The appts., comprising a mixing chamber, the block and a quencher, is also claimed as novel.

Abstract: The invention relates to a process for preparing acicular alpha -iron(III) oxide hydroxide by reacting an aqueous solution of an iron(II) salt with aqueous solutions of alkali metal hydroxides at elevated temperature and oxidising the suspensions thus obtained of iron(II) hydroxide with oxygen-containing gases to give the alpha -iron(III) oxide hydroxide.
