Title: Rotating torsion pendulum with spheres - mounted on thin wire or tape for disturbance insensitive year clocks
Inventor: FEHRENBACHER WOLFGANG
IPC: G04B17/10
Filed: 1973-10-30
Abstract: The torsion pendulum is fitted with spheres and rotates in a vertical plane. It is designed for so-called year or 400 days clocks. The pendulum is free to rotate with a torsion spring in the form of a thin wire or tape. The movement is designed to work without being influenced by outside disturbances. The pendulum consists of two parts: one connected to the torsion spring, and the other making up the mass, being the heavier and longer part. A flexible, elastic element keeps the two parts together in a working relationship. If the pendulum is forced round in one direction it does not loosen or damage the torsion spring.

Title: Vehicle reactive transmission system - has reciprocally connected components weighted to absorb and store energy
Inventor: SCHWARZ HELMUT
IPC: B60K8/00
Filed: 1975-01-30
Abstract: To absorb and store kinetic energy, all components of the transmission system can be weighted, without increasing the inertia of the mass of the vehicle. Transmission system and vehicle mass are reciprocally coupled together, so that the weights make the vehicle quicker to react. The planetary shafts are used to accommodate the weights, since they are subject to both rotary and centrifugal force, and thus their energy-absorbent capacity is correspondingly increased. The components absorb braking energy and the inertia is used in assisting the engine to reaccelerate the vehicle.
