Title: Connection between a dental implant body and a superstructure
IPC: A61C8/00
Filed: 1983-07-15
Abstract: In a connection between a dental implant body and a superstructure which is connected with a central supporting element which engages in a correspondingly shaped pocket drilled in the dental implant body and is mounted so as to be movable in this pocket drilled using a plastic jacket, the problem arises of how to improve the connection between the dental implant body and the superstructure so that the superstructure placed on the inserted dental implant body can no longer change its position in the dental constellation and therefore need not be exchanged, while at the same time the mobility of the superstructure remains unaffected and bacteria-tight connection is guaranteed. This object is achieved in that the end of the supporting element projecting into the pocket drilled in the implant body has the shape of a spherical shell, in that the plastic jacket extends maximally up to the transition to the spherical shell-shaped end of the supporting element and the supporting element sits with its unjacketed end directly on the end of the hole drilled in the implant body, which end has the shape of a hollow spherical shell, and in that a bacteria-tight connection is obtained between the supporting element and the plastic insert and between the latter and the implant body.

Title: Method for controlling a braking or ballast resistor in a DC voltage substation
Inventor: CIESSOW GUENTER ING GRAD
IPC: H02P3/12
Filed: 1983-09-13
Abstract: In order to control a braking or ballast resistor in a DC voltage substation, especially for railway supply, having rectifiers which are not capable of feedback, in which the braking or ballast resistor is connected in series with a DC actuator and this series circuit is connected in parallel with a mains or buffering capacitance, and in which the connection of the braking or ballast resistor is made dependent on specific reverse current and/or limiting values, a method having the following features is proposed:   - the operational use of the DC actuator (8) is made dependent on the instantaneous value of the voltage occurring at the substation (1) - the duty ratio  alpha  of the DC actuator (8) is matched to the magnitude of the reverse current, taking into account a regulated minimum current of the converter through which current passes upstream - operational blocking of the DC actuator (8) takes place, initially as a function of time, in the event of a drop in the reverse current with a slow reduction in the duty ratio  alpha  until the minimum current in the converter (1) is reached and, once again in a time-delayed manner, by switching off.   The time-delayed switching-off takes place when the DC actuator (8) has not been driven at a level above the minimum current at all during the time delay. As a result of the method according to the invention, otherwise [lacuna] - because of the line inductances as a consequence of the relatively large distances between the substation and the vehicle ...
