Abstract: A method for introducing an accurately dosable amount of mercury into the discharge vessel of a fluorescent lamp, wherein both sides of the discharge vessel are connected to a lamp receptacle; and the discharge vessel is charged with a gas stream via the lamp receptacle and is filled, with a predetermined amount of mercury. During or after dosing the amount of mercury to be introduced, the mercury is brought in a dosed volume in the form of a single, coalescing drop, then the entire amount of mercury to be introduced is transported into the discharge vessel, while still maintaining the previously formed drop. A change-over mechanism guides the gas stream past the drop via a bypass channel and blocks the bypass channel such that while the bypass channel is blocked, the gas stream is guided over the dosed volume and drags the drop along with it into the discharge vessel.

Abstract: A method is proposed for introducing an accurately dosable amount of mercury into the discharge vessel of a lamp, in particular into a straight fluorescent lamp, wherein both sides of the discharge vessel are connected to a lamp receptacle; and the discharge vessel is charged with a gas stream via the lamp receptacle and is filled, moreover, with a predetermined amount of mercury via a mercury introducing channel. Furthermore, it is provided that during or after dosing the amount of mercury to be introduced, the mercury is brought in a dosed volume in the form of a single, coalescing drop, and then in a fill step the entire amount of mercury to be introduced is transported into the discharge vessel, while still maintaining the previously formed drop.

Abstract: In a device for the packing of fluorescent ring lamps (1, 2, 3) comprising each a blank (4, 5, 6) at sheetlike material, preferredly corrugated board, which has been formed by folding along bending lines and by insert joints or glue joints into a planar envelope which at least partially covers and protects the respective lamp (1, 2, 3) and has two flat faces (10, 11; 12, 13; 14, 15) enclosing the lamp therebetween, a plurality of envelopes (7, 8, 9) of different sizes for the reception of lamps (1, 2, 3) of also different sizes is provided, the largest envelope (7) of which at its two flat faces (10, 11) having cut-outs (16, 17) which are adapted as to their dimensions to the dimensions of envelopes (8, 9) of smaller sizes for frictional and/or interlocking reception of same, so that from each face at least one smaller envelope (8, 9) can be inserted into the volume of the larger envelope (7) in such a manner that by several single packages there is formed a joint package which in assembled condition does not
