(DE4125704-A1)      The mechanism unfolds a stack of components (Al-An) joined together in pairs and resting one on top of the other in the folded state. Adjacent components hinge together on common axes.    Each pair of adjacent components has two parallel hinge axes (e1,c2,f1,d2) when in the folded state. Each component is joined to the adjacent one by two strips (G12,H12) hinging on the respective axes. The latter can extend along opposite side edges of the components, while locking devices can be provided to hold the components in the folded and/or unfolded position.    USE/ADVANTAGE -   Wide range of use, offering different ways of unfolding partic. useful in space whose element of a solar panel are mounted on an artificial satellite. Shelf elements for storing materials and presenting for retrieval on demand.

(DE4125704-C2)      The transport container, esp. for solar panels stacked on edge contains a gas bag arrangement (1) with two interlocking E-shaped gas bags. These use a valve system to control their pressure, which includes an electrically controlled spiral spring (7) at top and bottom.    Each spring is housed inside a two section telescopic sleeve (8) so that the position and slope of a plate (4) with a soft rubber layer (3) is controlled inside the container. The plate pivots about a grommet (5) fixed to the container base (6). The spiral springs are fixed between the container sidewalls (2) and the plate.    ADVANTAGE -   Contents are safely protected during alteration of members.    (DE4143356-C2)      The pulley cord drive has a memory metal coil spring (4) providing the drive force for both directions of rotation of the pulley roller (1), when the expanded coil spring returns to its original condition, in response to an applied electrical stimulation.    Two separate rollers (1) at each end of a roller shaft (2) are each wound with a cord (3) attached to a respective memory metal coil spring (4) at its free end, so that one coil spring (4) is expanded as the other contracts.    USE/ADVANTAGE -   Lightweight drive for use in space vehicle, or for operating automatic door or window.
