11 11 For the straightness measurement we have cut 2 couplers

13 13 The engraved lign is not to be lost in the orientation of the discs after the cuts

14 G. Riddone, Preparation for the measurement of straightness for the cells after bonding and of the couplers after brazing Mesures 1 Mesures 2 Alignment of cells 0 and 20 is 0 in the vertical and horizontal axis
