  • Patent number: 5458419
    Abstract: A flexible bulk goods container (1) with a container body (2), which can form a bulk goods accommodating space, is filled and emptied over a connector/outlet arrangement (3, 4), can be lifted by means of carrying loops (5) or the like and is preferably made from a coated basic weave, particularly of polypropylene that is electrically conductive due to integrated conductors. As a basic weave, a ribbon-like fabric is provided, in which, at a distances of not more than 30 mm in the warp or in the filling, a basic weave ribbon (6, 7) is replaced by an electrically conductive ribbon (8) of a plastic film material forming the electrical conductor, with a transverse extent corresponding essentially to that of the basic weave ribbon (6, 7) is substituted and/or assigned to the basic weave ribbons (6,7) in an essentially congruent arrangement.

  • Patent number: 5310416
    Abstract: The separation process and apparatus is based on conducting the explosive gas or vapour through a mass transfer column which is charged with an absorbent and filled with an electrically conductive packing. The packing (2) of the mass transfer column (1) must be earthed and have such a dense lattice spacing that no electric charge sufficient for ignition can accumulate at any point in the packing. Under these conditions, a non-conductive electrostatically chargeable liquid may be used as absorption liquid.
