Abstract: The blister pack comprises a base portion and a cover layer. The base portion comprises a hollow chamber that contains a soft hydrophilic contact lens and a sterile aqueous preserving solution, and a substantially flat flange that extends right round the outside of the hollow chamber. The cover layer is releasably sealed to the flange in a sealing zone that extends right round the circumference of the hollow chamber. The flange comprises a grip region that extends from one side of the hollow chamber beyond the sealing zone and is covered by a corresponding grip region of the cover layer but is not sealed thereto.

Abstract: At least one hanger rail having opposite ends is provided to support a plurality of parked vehicles. Two conveyor lines are associated with the hanger rail and extend transversely thereto to deliver the vehicles to one hanger rail and to receive parked vehicles from the other hanger rail means. Each conveyor line is associated with a respective end of the hanger rail, and the two conveyor lines are driven in mutually opposite directions of conveyance. Each conveyor line comprises an endless series of vehicle carriers, each of which is adapted to carry one of said vehicles and is of like cross section as the hanger rails.

Abstract: A drive system for a workpiece table of a machine tool, especially a gear cutting machine, which includes two worm wheel drives of different transmission ratio, each worm wheel drive including a worm and a worm wheel. The worms of the worm wheel drives being adapted alternately to be drivingly connected to a drive shaft. The worms of the worm wheel drives are drivingly connected to each other while the transmission ratio of this transmission connection of the two worms equals the reciprocal transmission ratio of the worm wheel drives with regard to each other. The worm wheels of both worm wheel drives which are rotated in the same direction and at equal speed which latter depends on the respective coupled worm wheel drive, are coupled to each other as well as to the workpiece table.
