Abstract: In a double-mass flywheel the flywheels of which are coupled with torsional flexibility by at least one set of at least two helical springs (31, 31'), it is proposed that the end spring (31') of the spring set arranged in a channel (29) encircling the axis of rotation (9) of the flywheels in a circular arc is pivoted to control elements (39, 53) of the flywheels via an endshoe (41). For this purpose, the endshoe (41) and the control elements (39, 53) are provided with guide surfaces which have the cross-sectional shape of a circular segment.
Abstract: An integrally formed injection molded bottle carrier having protective bridge bars extending between spaced-apart points of the frame and above and across the upper end of each bottle to protect and prevent removal of the caps of the bottles without concealing the caps from inspection.
Abstract: A film card selection device for use in an automatic microfilm display apparatus is provided with a switch for sensing that a film card has been selected.
