Abstract: A method for compacting and/or filling of pulverulent materials into rigid or flexible containers in the course of which the pulverulent material is filled into the container with the help of a pipe in relative motion to the container, and separated from the gas, for example air, transported along with the help of a separation device which surrounds the pipe and is fitted to the container cross section. The pulverulent material is retained in the container with the help of the separation device, while the gas escapes through the gas permeable separation device.

Abstract: There is provided a process for the production of sulfur containing organosilicon compounds of the formula (I) Z -- Alk -- S.sub.x -- Alk -- Z, where Z is the grouping: ##STR1## in which R.sup.1 is an alkyl group having 1 to 5 carbon atoms, a cycloalkyl group with 5 to 8 carbon atoms, the benzyl group, phenyl or phenyl substituted with at least one methyl, ethyl or chloro group, R.sup.2 is alkoxy of 1 to 4 carbon atoms, methoxyethoxy, cycloalkoxy with 5 to 8 carbon atoms, phenoxy or benzyloxy, R.sup.3 and R.sup.4 are alkyl of 1 to 3 carbon atoms or hydrogen, Alk is divalent saturated hydrocarbon group having 1 to 5 carbon atoms or such a group interrupted by --O--, --S-- or --NH-- and x is a number from 2.0 to 6.
