Abstract: The invention relates to a method for covering a plastic cup with a print substrate (2) that is flatly folded together along two folding lines (5). The inventive method comprises the following steps: A form (12) having the contour of the plastic cup is provided with an insertion slot (13) for the folded together print substrate (2). The flatly folded together print substrate of the form is fed with an direction of insertion (11) transversal to the folding lines (5), whereby the diameter of the form (12) is smaller than the extension of the folded together print substrate (2) transversal to the folding lines (5). The folded together print substrate (2) is completely inserted into the form (12), whereby an automatic unfolding of the print substrate (2) and a placement against the inner wall of the form (12) ensues. A plastic cup is placed inside the form (12) that is lined with the print substrate (2).

Abstract: Acoustic transducer having a piezo-electric element, including a lead section connected to the piezo-electric element, the lead section being in the form of a metallic body having a high specific attenuation.

Abstract: The invention relates to a process for the continuous preparation of photographic emulsions by a continuous flow process, in which a volume stream entering a pipe system flows successively through the various sections of this system corresponding to the individual stages of the process, such as the inlet points for introduction of the volume streams, mixing paths and ripening paths.

Abstract: A cutting tool consists of circular, rotatably mounted upper and lower blades, the upper blade extending past the periphery of the cutting shoulder of the lower blade and bearing resiliently against it. The thickness of the cutting shoulder of the lower blade is less than the distance of the said extending of the upper blade, and the material hardness of the upper blade is greater than that of the lower blade.
