Abstract: An oven for baking batter goods, in particular, a wafer oven, has several baking plates assigned to one another in pairs, and at least one heat source for tempering or heating the baking plates. Particularly efficient production of wafers or similar products can be achieved in that the baking plates are mounted in a wheel-like carrier that can be rotated about an axis so that they extend essentially radially away from the axis, at a distance from it. Furthermore, at least one heat exchanger may be assigned to the baking plates, in each instance, through which a medium tempered by a heat source and supplied by way of a ring line flows.

Abstract: A method for joining an initial section (3) of a film tube (2) which is wound up in a band-like manner on a reel (1) with an end section (4) of a second film tube (5) extending over subsequent processing stations, especially a packaging system, in an at least partly band-like manner, with the band-like initial and end section (3, 4) each having two mutually superimposed outer lateral surfaces (10, 11, 15, 16) which each converge in their boundary regions into two interposed, inwardly folded inner lateral surfaces (17, 18, 19, 20) which thus form an inwardly situated fold axis (S, T). It is provided for in accordance with the invention that in the two outer boundary regions of the initial or end section (3, 4) a tab (7, 27) each is formed by placing a cut, which tab is joined in a tension-proof manner with the opposite section (3, 4), with the initial section (3) overlapping the end section (4).

Abstract: The invention relates to an ultrasonic sensor with an adjustable detection range for use in gaseous media, preferably air. A threshold value generator generates threshold value curves that are fed to a comparator. The change in the detection range of the ultrasonic sensor, namely, the change in its switching point curve, is carried out by influencing the threshold value curves, whereby, in a selectable manner, the detection range can be adjusted either exclusively in the lateral extension of the sonic cone or else in the axial and lateral extensions of the sonic cone.

Abstract: The invention relates to a method for the production of a solid fragrance concentrate, by absorption of a liquid fragrance or fragrance mixture in a solid or solid mixture, using one or several surfactants and/or co-surfactants, solid at normal temperatures as solid or solid mixture, whereby the liquid fragrance or fragrance mixture is dissolved in the above at a temperature above the solidification temperature of the solid or solid mixture and the solution subsequently solidified by cooling. The solid or solid mixture comprises fatty alcohol(s) or a mixture of fatty alcohol(s) and fatty acid(s) and/or fatty alcohol ethoxylate and/or polyethylene glycol.
