To reduce the number of particles in an exhaust gas (A), in particular in the exhaust gas (A) from an internal-combustion engine, sulfur dioxide SO₂ which is contained in the exhaust gas (A) is at least partially catalytically oxidized, in the presence of ammonia NH₃ in a catalytic converter system having a catalytic activity which increases in the direction of flow, to form sulfur trioxide SO₃. The simultaneous presence of sulfur trioxide SO₃ and ammonia NH₃ in the exhaust-gas stream which is brought about in this way results in an agglomeration of the small and very small particles and reduction in the number thereof.

A manufacturable method for forming a highly reliable electrical interconnection. An electrical interconnection pattern is first formed in a dielectric layer on a semiconductor substrate as recessed regions in the dielectric layer. A conductive layer primarily comprising copper is thereafter deposited over the surface and in the recessed regions of the dielectric layer. The conductive layer is then reflowed to fill the recessed regions of the dielectric layer with substantially no void formation. This reflow process may also be used to improve the step coverage of any such copper layer deposited over the surface of a substrate to be used in conjunction with alternate techniques for forming electrical interconnections including photoresist patterning and etch.

The compound/curvilinear immiscible liquid separator has a separator section with an outer, elongated, cylindrical shell aligned vertically opening into an upper transition section and vapor dome at the top and a lower transition section and solid/heavy crude containment section at the bottom. A center column is disposed in the axial center of the separator section and a plurality of serially connected curved plates are disposed between the outer shell and center column to define an elongated curvilinear flow path having reverse flow pathways. An oil-water-gas mixture is introduced into the separator section under pressure past heating coils and through the curvilinear path, the lighter density oil entering and being removed from the top of the center column, and heavier sludge and brine collecting in the containment section. Gases bubble up through the center column and are removed from the vapor dome.

The present invention relates to a receptacle which comprises a generally elongate tubular body, a plurality of pellets of a predetermined size and shape containing a predetermined measure of active ingredient and filtration means disposed at or adjacent each end of the tubular body to retain the pellets substantially within the body.
