Patent DE-19721970-A1 (DE)
Title: Keyboard musical instrument damper e.g. for electronic piano
Inventor: INOUE SATOSHI
IPC: G10B3/00
Filed: 1997-05-26
Abstract: The damper (5a) includes an opening and a flap (4d) which is operated by a player. A damping unit which generates a damping force against the flap has static and moving parts. The damping unit generates a small damping force for relative motion of the parts in one direction and a large force for relative motion in the opposite direction. The connecting mechanism is located between flap and damping unit and acts as a changeover mechanism. The mechanism changes the damping unit between relative motion in one direction to relative motion in the opposite direction at an intermediate flap position on the path from closed to open position and vice versa.

Title: Planetary gear with high and low gear ratios
Inventor: BUTSCH MICHAEL DR ING
IPC: F16H3/62
Filed: 1997-11-13
Abstract: Planetary pinions (5) mesh with two outer gear rings (6,15), having slightly different number of teeth. Axial movement of the planet carrier (7,8,9) and the action of springs (19,31,32) engage either toothed ring (23 with 24) or (25 with 26) to give low and high gear ratios between the input (2) and output (12). A planetary gear arrangement which can be switched between normal functional and differential operation includes two outer gear rings (6,15) having differing number of teeth. Toothed rings (23,24) are engaged through axial movement of planet carriers (7-9) and springs (19,31,32), and when engaged the planet carrier is locked to an output (12) and the gear arrangement acts as a simple planetary gear with low gear ratio. In this position the second outer gear ring (15) is idle. When subsequent toothed rings (24,25) are engaged, the drive actuates the second outer gear ring (15) to give a very high gear ratio.
