A direct vessel injection nozzle for minimum emergency core coolant bypass is disclosed. To reduce the vertical distance between viewing positions for the sights, the optic and the eye lens are truncated in order to position the optic predominately outside of a projection of a perimeter of the eye lens, the projection being parallel to the optical axis of the objective. The driving circuit has a driving signal generator that provides two different driving signals to heat the ink jet cells. If the descriptive information contains any criterion, then the media is stored in memory, wherein the stored media is targeted to a user’s communications device. The present invention further provides the N-methylenecyclopropanamine derivatives used as starting compounds in this process according to the invention, and their use for the preparation of substituted N cyclopropanamines.
