27. In a window blind closure system having a component housing suspending a plurality of blind segments and a baton coupled to a shaft means for moving said segments between open and closed positions, the improvement comprising:
-
a. a second housing attached to said first housing, b. means in said second housing coupled to said shaft means in said first housing for moving said blinds between open and closed positions, c. a power storage device in said second housing for storing energy when said blinds are manually moved from a first one of said open or closed positions to the other, and d. means in said second housing for selectively coupling said power storage device to said shaft means for moving said blind segments from said other position to said first position.

28. An improved method of window blind louver control of a plurality of blind louvers suspended from a component housing and moveable between open and closed positions by means of a baton coupled to a shaft, the improvement comprising the steps of:
-
a. attaching a second housing to said first housing, b. coupling means in said second housing to said shaft means in said first housing for moving said blinds between open and closed positions, c. storing energy in a power storage device in said second housing when said blinds are manually moved from a first one of said open or closed positions to the other, and d. selectively coupling-said power storage device to said blind segment shaft in said component housing to move said blinds from said other position to said first position.
