Title: Deposit and tax stamp which cannot be removed undamaged
Inventor: WOLF OSKAR
IPC: G09F3/00
Filed: 1989-03-01
Abstract: The conventional price-marking stamps are made even more difficult to remove by closer and greater longitudinal perforations and machined-in predetermined tearing points. In the case of deposit bottles additionally a remark: on return (e.g. DM -,50) is sufficient as marking for bottles (or other) in order to make these recognisable as deposit items to be returned. The final seller/deposit money repayer is anyway recognisable from his adhesive stamp and must repay. With a deposit stamp which is at least difficult to remove, when the deposit is rendered unusable, the deposit stamp is therefore also destroyed.

Title: Rigid, driven leading axle
Inventor: SCHUSTER MAX
IPC: B60K17/30
Filed: 1989-03-16
Abstract: The leading axle is newly designed with respect to the pivot bearing. An axle body has outwardly pointing bearing bolts at its fork-shaped ends. The said bearing bolts are held in the axle body with a defined pretensioning by means of tapering seats and bear tapered roller bearings at their free ends. A hub carrier is coupled to the axle body via the tapered roller bearings, the tapered roller bearings being supported axially and radially on the bearing bolt. By virtue of the compact design of the articulation head, a small steering rolling radius can be achieved. In addition, the distance between the intersection points of the axis of rotation with the central plane of the wheel and the pivot axis is very small, as a result of which good locking angles with otherwise identical parameters are obtained.
