A vacuum cleaning device comprises a unit () for aerodynamically affecting dust particles and/or a surface to be cleaned. The unit () comprises a housing () having a housing wall () encompassing two internal sections (), and a movable surface () arranged at an interface of the two sections (), wherein a portion () of the housing wall () delimiting a first section () is provided with at least one opening (), and wherein means for actuating the movable surface () are arranged in a second section (). A portion () of the housing wall () delimiting the second section () is adapted to at least hinder exchange of air between an inside of this section () and an outside of the housing () at the location of this section (), in order to at least hinder a migration of dust to the second section ().

Vacuum cleaning device

A heating system employs a ceramic substrate and a resistive layer. The resistive layer includes a thermally stable resin, which is filled with a conductive material. A method of manufacturing such a heating system involves a provision of a ceramic substrate and an application of a resistive layer on the substrate. In the method, the resistive layer comprises includes a thermally stable resin, which is filled with a conductive material. Before application of the resistive layer, an adhesion promotor is applied on the ceramic substrate.

Heating system

A heating element employing a substrate, an electrically insulating layer, and a resistive layer. The electrically insulating layer of the heating element includes a first layer that is obtained by a sol-gel process, and a second layer including a resin.
