The Italian Chapel, still extant today, is disposed upon an obtrusively elliptic plan, and it is this chapel's ovaloid structure that is thought to have been an architectural model that ultimately triggered Kepler's astronomical discovery (Horsky 1990:189-190).
Another Baumer success is the 900 feeding system, which allows handling rectangular, ovaloid, and shaped containers--even the unsteady ones--both with film and with wraparound carton.
