Abstract: An apparatus for the loosening of wallpaper or the like from a substrate by steam. The apparatus includes a steam generator and a working plate, the steam generator being connected to the working plate by a flexible steam hose. The working plate is formed as a steam bar, which includes a U-shaped housing to which a handle is attached. A cover plate or a side piece can be detachably joined to the housing at one or both ends of the housing. The cover plate or side piece is closed at the end opposite the housing, and by choosing to attach either a cover plate or a side piece to the housing, the working area provided by the working plate can be adjusted. The apparatus thus provides a tool which can be easily and quickly adapted to loosen wallpaper in a variety of situations, including making it possible to steam both entire sheets of wallpaper and small portions of wallpaper in small areas where access to the wallpaper is poor.

Abstract: A method and an apparatus are provided for stopping a motor-driven pressure generating pump of a system for coating workpieces with atomized liquid coating material in case of an empty material reservoir or a leakage in a material supply from a material reservoir to the pump or from the pump to an atomizer. The pressure and/or the volume flow at the pump outlet and/or the speed of the pump piston or a value dependent thereon are continually measured. The measured values are then converted to electric signals to be input to an electronic analyzer and analyzed therein. If, during operation, the pressure and/or the volume flow drops below a predetermined value and/or the speed of the piston exceeds a predetermined value, the electrically controlled driving connection between motor and pump or the power supply to the pump motor will be cut-off by output signals from the electronic analyzer.

Abstract: In a conveying pump having a cylinder introducible into a reservoir and having a pump piston, whereby the conveyed medium is supplied via an ascending line to a discharge line, an ascending line formed of two sections adjustable relative to one another is provided. The ascending line can be locked at different heights to vary the length of the ascending line so that the conveying pump can be used for reservoirs of different heights without deteriorating the conveying capacity of the pump. This adaptation can be performed easily and quickly. In addition, the conveying pump can be taken apart and easily cleaned, and component parts can be easily replaced.
