Abstract: A multi-purpose kitchen appliance comprising a first container closable by a cover in which a first driven working utensil can be inserted for processing food stuffs which can be coupled via a first connector with a drive spindle projecting through the base of the electric motor in the multi-purpose kitchen appliance. A second, smaller container may be inserted into the first container. A second utensil in the second container can be coupled to the drive spindle via a second connector. A sealing lip is arranged on the edge of the aperture of the second container which, when the latter is inserted in the first container, forms a seal on the underside of the cover when the cover is fitted on the first container.

Abstract: Reaction products of dibutyl tin oxide with selected aromatic aminocarboxylic acids, a process for their preparation and their use as catalysts for the preparation of polyurethanes.

Abstract: The invention is directed to a bread toaster with a removable crumb tray, including devices which prevent operation of the bread toaster when the crumb tray is not inserted and, secondly, which ensure that operation of the bread toaster is stopped when the crumb tray is removed during toasting.

Abstract: The invention is directed to a method for the manufacture of a heating unit comprising an insulating body having a front and a back side, one or several heating conductors arranged on the front part of the insulating body, and contact and fastening elements. The heating conductors are connected to the insulating body by means of the contact or fastening elements. To manufacture single- and double-faced heating units in a common process, it is proposed that in a first operating sequence the contact or fastening elements are rigidly fixed together with the insulating body by means of anchoring arrangements and that in a second sequence the one or several heating conductors are contacted with the contact or fastening elements.
