Inventor: FUCHS KARL-HEINZ
IPC: B05B11/00
Filed: 1991-03-28
Abstract: In a dispenser (1), the actuation tappet (20) is guided with respect to the base element (2) with the outer circumference of an elastically deformable shaft section (32) essentially free of play to such an extent that, on actuation, this shaft section leaves the associated slider guide (43) and is then released for the purpose of deformation, in order, for example, to open an outlet valve (21).

Title: Television signal colour edge flickering effect reduction - comparing of points in part images with colour difference signals being used from adjacent cell
Inventor: GRIGAT ROLF-RAINER DR
IPC: H04N9/64
Filed: 1991-05-02
Abstract: The process is used to reduce the flickering effect that occurs when a television image is generated that is composed of two half frames.
