dumping position “so that no trash can fall from the trash
receptacle prematurely” (translation, page 3). The trash
receptacle swivels only in the final part of its lifting path

which the lifting arms and the forks carried thereby each are
equipped with position sensors. However, this system operates

appellants’ invention is directed and, from our perspective,
without inherently minimizing the height in the claimed
manner.
Tonsor is directed to a multi-purpose industrial vehicle
that can be equipped with a pair of lift arms alternatively
outfittable with several implements, of which a bucket and a
pair of lifting forks are illustrated. Briefly stated, Tonsor
provides a control system that can be matched to the
implement. For example, when the bucket is installed, the

push earth or the like along the ground, and a second
