Patent DE-3643219-A1 (DE)
Title: Root pin for insertion in the root canal of a tooth stump
Inventor: WEISSKIRCHER HANS-WERNER DR ME
IPC: A61C13/30
Filed: 1986-12-18
Abstract: Superstructures of stumps of teeth that have been pretreated endodontically and whose crowns are fractured, weakened or destroyed by caries, can be restored with the aid of a prefabricated pin which is inserted in a recess in the stump and whose section projecting beyond the stump serves as a carrier for a dental crown or the like. Fastening of the prefabricated pin is effected in the stump with the aid of a cement, plastic or the like, or/and with the aid of a screw thread. The conventional root pins require a bore that has been provided with high accuracy in the stump in order to ensure optimum hold of the root pin coupled with an extremely low stress on the root canal. This involves the danger of the canal wall of the stump being broken through in the case of narrow or very conical roots. Moreover, it is diffult to find sufficient hold for the root pin in root stumps having very wide or asymmetric root canals. The root pin according to the invention is to be easily handled in a time-saving manner and at the same time insertable without any major pretreatment of the root canal. The root pin carries flexible lamellae extending in the radial direction and arranged in planes standing at a distance from one another in the longitudinal direction of the pin.

Title: Direct-current arc furnace system and method for its operation
Inventor: BUEHLER KARL
IPC: H05B7/156
Filed: 1988-03-26
Abstract: In a direct-current arc furnace system having a positive (2) and a negative (3) electrode, the electrode adjusting devices (4, 5), which are assigned to these electrodes, are independent of each other and are integrated into a respective voltage control circuit. The furnace is in this case operated in such a manner that the length of the arc of the positive electrode (2) is controlled during the melting phase as a function of the radiation load of the furnace wall and that the arc length of the positive electrode (2) is successively shortened as the degree of melting increases and the furnace walls become increasingly free. This allows for a more stable operation in various phases of operation and increases the service life of the furnace walls. <IMAGE>

Title: Apparatus for feeding laundry articles to a mangle
Inventor: WIEBESIEK WILHELM
IPC: D06F67/04
Filed: 1988-06-04
Abstract: In apparatuses for feeding laundry articles to a mangle or the like, the laundry article first has to be spread out before it is transferred to a feed conveyor (22) and transported by the latter to the mangle. It is necessary, for this purpose, for the upper edge of the laundry article to run as straight as possible. In known apparatuses of this type which conventionally grasp only the opposite corners of the laundry article by means of a pair of outer clips (27, 28), relatively high tensile forces have to be exerted on the laundry article from the straight alignment of the upper edge of the latter. This can result in damage to the laundry article. In order to avoid this, it is proposed by the invention to provide at least one further middle clip (29) for raising a middle region of the upper edge of the laundry article. The middle clip (29) raises the sagging upper edge of the laundry article, without an appreciable additional pull on the laundry article having to be exerted for this purpose as a result of a correspondingly vigorous moving apart of the outer clips (27, 28). <IMAGE>

Title: Method for cleaning capillary fibres built into a dialysis filter
Inventor: VALLOMTHARAYIL THOMAS
IPC: B01D65/02
Filed: 1988-09-06
Abstract: A method for cleaning capillary fibres which have a semipermeable wall and are built into a dialysis filter provides that a wash liquid is passed from the outside through the wall of the capillary fibres and is lead off at one end of the capillary fibres. With current dialysis filters this can be achieved by feeding the wash liquid through one dialysate connection and leading off through one blood connection. The remaining connections for dialysate and blood remain sealed during this. To increase the cleaning effect, the connections opened in a first phase are closed in a second phase and accordingly the connections closed in the first phase are now opened.

Title: Device for the continuous determination of the filling volume of liquids in containers, especially in cylindrical containers installed lying down
Inventor: TEMPLIN MANFRED DIPL ING
IPC: G01F23/76
Filed: 1988-10-14
Abstract: Lying cylindrical containers, which are used, for example, in the field of filling stations, change their position or their inclination, which makes the determination of the filling volume very difficult. Conventional methods for the determination of the filling volume are limited to the manual determination of the filling level by means of a gauging rod in the container, the manual conversion of the gauged filling level by means of tables, to the costly "wet surveying" of the respective container, as well as to quantity indications of flow meters. The new device determines not only the filling level and the temperature of the liquid but also the inclination of the container. In a preferred embodiment, the static and dynamic inclination of the container can also be determined metrologically and be taken into account with respect to the liquid volume actually present.
