Patent DE-3723643-A1 (DE)
Title: Improvement of teeth
Inventor: KIELINGER BERNHARD
IPC: A61C8/00
Filed: 1987-07-17
Abstract: Method of improving natural teeth by replacing them by artificial teeth made of a higher-quality material. Usually, teeth are repeatedly filled until there is only a remainder left which then has to be removed in a troublesome and painful way. The gap produced is then provisionally bridged by expensive bridges or an artificial denture. This is troublesome to the patient, expensive and unsatisfactory in the long-term. In the present invention, a higher-quality tooth is substituted for the old tooth, and this means a durable, inexpensive and least problematical solution for the patient.

Title: Arrangement and method for limiting the consequences of a core meltdown accident in nuclear power stations
Inventor: KUROCKIN VALERIJ
IPC: G21C13/02
Filed: 1987-07-25
Abstract: The invention concerns an arrangement and method for limiting the consequences of a core meltdown accident in nuclear power stations in which the containment with the reactor is located above operating compartments, in particular in existing nuclear power stations or those under construction in which the containment's bottom slab does not provide sufficient protection against melting. The invention provides that the operating compartment under the containment's bottom slab can be filled with stone chips via a conveyor line if an accident occurs. The operating compartment is provided with a high-temperature-resistant lining and can be sealed gastight and so that it will retain pressure by means of airlocks. If a core meltdown occurs, the lined operating compartment is filled with stone chips that are stored in a storage vessel and conveyed in a conveyor line; the operating compartment is sealed gastight and so that it will retain pressure by means of the airlocks. When the containment's bottom slab melts through, the molten core is absorbed, diluted and cooled to solidification by the stone chips within the operating compartment.

Title: Printing mechanism for typewriters or similar office machines
Inventor: GERKEN HEINER DIPL ING
IPC: B41J1/24
Filed: 1989-02-07
Abstract: In printing mechanisms for typewriters or similar office machines having a daisywheel with axial impression of the types, it is necessary for the carrier of the daisywheel (7) to be adjusted in relation to the roller platen (5). This is necessary in order to adjust the daisywheel to the correct printing height and to the correct rebound. The invention is based on the object of adjusting the interface of the daisywheel (7) towards the roller platen (5) using very simple means. This object is achieved in that bearing angles (34, 35) are arranged on the side walls (29, 30) of the printing-mechanism carriage (6) so as to be separately adjustable and retainable, in that the bearing axle (52) for the pivotable carrier (53) is mounted in bearing bores (51) of the bearing angles (34, 35), in that the bearing angles (34, 35) have catch lugs (55, 56) behind which spring-mounted pivoting levers (57, 58) can be engaged with catch cutouts (59, 60) in the operating position of the carrier (53), and in that the bearing angles (34, 35) have stop lugs (66, 67, 68, 69) for counter stops (70, 71) on the carrier (53) to limit the pivoting movement of the carrier (53). By means of simple adjustment of the bearing angles (34, 35) on the side walls (29, 30) of the printing mechanism (1), the carrier can be adjusted towards the roller platen by means of the adjusting device and the stop device for the daisywheel using very simple means. <IMAGE>
