Patent DE-3902862-A1 (DE)
Inventor: LANGOWSKI HORST-CHRISTIAN
IPC: C23C14/00
Filed: 1989-02-01
Abstract: A method is described for the vacuum-coating of substrates, such as glass plates, foils, plastics substrates for optical discs etc., in which the substrates are introduced into a vacuum-coating arrangement and are vacuum-coated in accordance with a PVD (physical vapour-deposition) process such as for example cathode sputtering or vapour-deposition. In order to avoid pinholes in the coating the method is carried out in three steps, namely a first PVD step, in which the substrates and any particles adhering thereto are coated; a particle-displacement step in which the coated particles are displaced from their initial positions on the substrate; and an additional, second PVD step, in which the substrates are coated a second time to cover the defects formed in the coating by adhering particles in the first coating step.

Title: Contact-delaying container for operating a washing machine with liquid soap
Inventor: PAETAU ANDREAS
IPC: D06F39/00
Filed: 1989-02-27
Abstract: The contact-delaying container makes it possible to wash with liquid soap in domestic washing machines, since it delays the coming together of soap and water until the water has been softened.

Patent DE-3906358-A1 (DE)
Title: Tilting/sash window for stalls (barns) with electric ventilation
IPC: E05C19/16
Filed: 1989-03-01
Abstract: The window sash (20) is locked to the window frame (10) by a steel bolt (25) which is held in the closed position by a current-carrying coil (14), fastened on the window frame, by a magnetic force. The coil obtains its current from a transformer fed by the electric ventilation. If the electric ventilation fails, then the coil loses its current, the steel bolt falls out, the locking is eliminated and the sash tilts automatically into an open position as a result of the special arrangement of the articulation, as a result of which natural ventilation is obtained. <IMAGE>
