Patent DE-19728730-A1 (DE)
Title: Sphere puzzle of fixed and movable ring-circuited segments
IPC: A63F9/08
Filed: 1997-07-04
Abstract: The movable sphere segments (2a-3a) are guided by cams (12,13) and complementary guides (12a,13a) fitted on the underside of the segments and making point contact or again releasably bolted to one another with clearance. Bolting is effected by a latch connection (18) to be made and broken radial to the preferably hollow sphere. Circular rings on a support structure on the fixed segments inside the sphere serve as cam guides. Guide grooves (17) let into the preferably hollow plastics sphere itself take the bases of the control cams (12,13), with the movable segments spaced both sides of the guide groove walls. The movable segments make point contact with the guide groove (17) walls and bottom. The cams form grooves let into the sphere or the plastics support structure to take the guide elements (13a,14a) riding the cam-designed underside of the movable segments (2a,3a).

Title: Drying of sterilised goods in a sterilisation chamber
Inventor: WAYDBRINK EBERHARD VON DER DIP
IPC: B65B55/02
Filed: 1997-07-31
Abstract: In a process and apparatus for drying sterilised goods, especially for the packaging of sterilised goods, the drying process is effected using sterile air and follows the sterilisation process. The drying is performed in a fractionated process in which the air pressure is raised and lowered in cycles. Preferably the maximum pressure is 0.7-1.2 bar and this is subsequently lowered at a rate of 4-8 bar/minute, driving out moist air and condensation. The process is terminated when the moisture content of the air released from the chamber has fallen below a predetermined level.

Title: Motor vehicle gas change valve tappet switching
Inventor: SCHIMONSKY LOTHAR VON DIPL ING
IPC: F01L1/14
Filed: 1998-02-04
Abstract: The tappet coupler (9) is shifted to the de-coupling position by a mechanical setter (25) passing radially through one or both cams (6, 8) in response to a control slide (20) running along the camshaft (19). The coupler (9) comprises circular tongs whose legs encircle the sector (4) directly adjoining the subject valve. Thus in coupled position, the tongs legs seat into rim recesses (13) round sector and so round the high-lift cam (6).  These recesses line up with the legs in one cam contact phase as opposed to the de-coupling phase when the setter (25) swings in at its radially outer end as the cams rotate and in this way spread the tong legs outwards by one thickness of this setter end and so free the sector rim recesses. The shaft is centrally bored out (18) for the slide (20) whose cams at the setter form a vee-track (21) traveled by the inner end of the setter in the axial direction so that the setter runs on one top end (22) of the track when de-coupled but on the lower end (23) of the track when coupled.

Patent DE-19830869-A1 (DE)
Inventor: LIEBLER GEROLD
IPC: E04B1/98
Filed: 1998-07-10
Abstract: The aim of the invention is to specifically dampen the torsional oscillations of a bridge (10). The vertical acceleration is measured (14, 15) on both sides of the longitudinal axis (13) of the bridge and an actuating signal for controlling actuating elements (20, 25) on both sides of the longitudinal axis of said bridge is produced. The actuating signal drives the actuating elements on the two sides of the longitudinal axis of the bridge in opposition. The invention also relates to a device for carrying out this method. A damping mass (19, 24) is maintained on each side of the longitudinal axis of the bridge by means of hydraulic cylinders (20, 25). The acceleration values are delivered to a control device which then subjects the cylinders to a pressure which will reduce the torsional oscillations of the bridge, according to the difference between the vertical accelerations. The inventive method and device are suitable for damping the torsional oscillations of extended bridges, such as suspension bridges.
