Abstract: A component having electrical connector elements for making contact with a circuit board, optionally having additional securing elements for mechanical stability after soldering or positioning devices for supporting components with an unfavourable center of gravity or supporting elements which can optionally be removed after the soldering process. The positioning devices or supporting elements serve to position components with different forms on a circuit board and to keep them in the correct orientation for the soldering process. Fitting takes place in a force-free manner and thus favours automation and the use of for example pick-and-place robots which take hold of and move the particular component via the positioning device connected thereto, engaging with and/or around either a contact element or a supporting element. The support of the positioning device allows a stable state during the soldering process. In a corresponding manner, methods for carrying out the soldering processes are specified.

Abstract: A sealing wall grommet for a wall of an electrical device, comprising a flange-like installation sleeve for receiving a plug part having electrical contacts, to which there can be connected in a plug-in manner a mating plug part which has a securing screw-in sleeve that can be screwed to the installation sleeve and acts as a pull-out prevention means for the mating plug part, wherein the installation sleeve is designed to receive a plug-in section of the plug part and has an abutment which is connected to the installation sleeve, runs around the outer circumference thereof and has an annular seal for the wall. According to the invention, a tubular tensioning sleeve is provided for tensioning the installation sleeve, which tensioning sleeve has at least one inwardly projecting latching means that cooperates with a mating latching means formed on the outside of the installation sleeve.

Abstract: A brushing and drying apparatus for hair comprises a device for generating an air flow which can be adjusted to a desired temperature and a number of curlers which can be fixed in the hair which is being treated. An air distributor device, such as an air distributor vessel, is connected or connectable with an air flow-generating device. The distributor device contains a multiplicity of air exit or outlet openings. There are provided a number of hoses which are connected at one end with the outlet openings of the distributor vessel and at the other end with a related curler.
