Activation ofCLN1andCLN2G1Cyclin Gene Expression by BCK2

The eccentric shaft is connected via the connecting rod and slider to single arm levers projecting at both sides away from the slider. At their ends remote from the slider the levers are supported via threaded spindles at the frame of the punch press. Groups of link members are pivotally mounted to the levers. These groups of link members are connected to double lever pairs arranged symmetrically relative to the center line of the frame of the press. Every double lever is pivotally mounted to a pressing column. The pressing columns of a respective pair of double levers are mounted to a relative ram. Each ram is guided by three guide columns, of which two are rigidly connected to a ram and one to the frame of the press. By the symmetrical dividing of the driving structures and the two rams derived therefrom the punch press is given an extremely long space for mounting the tools without that the height of the punch press, the allowable rated output and the moving masses must be kept overly large.
