Abstract: A container (1, 61, 115, 116) has a main unit (2, 62, 116, 161) and at least one additional unit (3, 4, 63, 64, 117, 118, 162) with one side which is open to the main unit (2, 62, 116, 161) whereby each additional unit (3, 4, 63, 64, 117, 118, 162) can be extended from and reeled back into the main unit (2, 62, 116, 161). In accordance with the invention there is one lift device each (44, 45, 49, 50, 107, 108, 109, 110, 111, 124, 137) through which the respective additional unit (3, 4, 63, 64, 117, 118, 162) can be lowered while or after it is extended so that the floor (10, 17, 22, 65, 70, 74, 119, 120, 121) of the main and the additional unit (2, 3, 4, 62, 63, 64, 116, 117, 118, 161, 162) are on the same level and through which the respective additional unit (3, 4, 63, 64, 117, 118, 162) can be lifted before or while it is reeled in so that it can be reeled into the main unit (2, 62, 116, 161).

Abstract: To improve the uniformity and the adhesive strength of luminophore layers, a process is proposed in which the luminophore is enveloped with glass flux and the enveloped luminophore is applied to a luminophore carrier at elevated temperatures by using acrylic resin.

Abstract: A process is disclosed for producing a low-reflection luminophore layer in which an aluminum-plated metal plate is annealed under vacuum, and the luminophore is sintered onto the surface thus blackened by means of glass solder.
