Abstract: The present invention relates to a method for filling a multitube catalytic reactor and to a set of inserts suited to implementing this method. The method of the invention is based on the use of inserts of different types allowing superposed layers of catalysts to be placed in the reaction compartments. The heads of the inserts are visually distinct according to the type of insert, making it possible to avoid filling errors and thus allowing the various layers of catalyst to be filled reliably and simultaneously on a reactor scale.

Abstract: A protective coating is used in heat treating a coated glazing panel.

Abstract: The invention relates to a plug device for a standard electrical or optical connection cord (10) provided at an end with a cord plug (12) having a body which includes an external mechanical latch (16). The plug device comprises a plug body (20); a plug adapter (22) having external fastening means for engaging in said plug body; a packing body (30) including packing (32) of cylindrical shape; and a link part (28) having a first end for connection with said plug body and a second end for connection with said packing body; said plug adapter having an internal profile suitable for receiving said cord plug body (12) and having fastening means for engaging the cord plug body and for holding said latch (16) of the cord plug body in its inactive position.

Abstract: The invention concerns a method and a device for heating glass sheets in an oven, which are transported therein by a conveyor with horizontal rollers and wherein their surfaces are heated by heating means arranged above and beneath the sheets, by radiation and by forced convection by injecting hot gas into the oven, the gas injected beneath being in the form of jets whereof the axis of symmetry is oblique relative to the forward moving direction of the sheets on the conveyor and directed towards their lower surface.

Abstract: An inner layer of strands comprises at least one strand; each strand consists of three or four twisted elementary fibers without any central elementary fiber. The ratio of the twist pitch of the strand to its diameter is between 7 and 19. The inner layer may be surrounded by an outer layer which also comprises twisted strands.

Abstract: A laminated glazing pane comprised of at least two sheets of vitreous material joined together by an intervening layer of plastic material given improved sound attenuation properties by constructing the pane in such a manner that its base frequency (f) is between 0.70 and 0.97 times its theoretical base frequency (f.sub.0).

Abstract: In the severing of bodies of glass or vitrocrystalline materials by the application of a laser beam, the severing operation is improved by employing a beam of which at least the predominent wavelength is such that at least 10% of the beam energy penetrates the body to a depth of at least 0.2 mm.
