Patent DE-4319986-A1 (DE)
Inventor: KIRCH JOHANNES
IPC: H01C7/12
Filed: 1993-06-11
Abstract: In an electric overvoltage diverter, especially for medium voltages, having a function block (1) and a housing (5) of insulating material surrounding it, the housing (5) is made of an elastically expandable material so that the function block (1) can be inserted into the housing (5) by elastically expanding the latter and easily removed therefrom. This simplifies the separation of the various materials of which the overvoltage diverter consists during the latter's disposal and makes them re-usable. The housing (5) of the overvoltage diverter is preferably made of silicone rubber.

Patent DE-4326382-A1 (DE)
Title: Method and computing device for calculating the field of a physical process
Inventor: EBERLE FRANZ ARNULF
IPC: G01R29/08
Filed: 1993-08-05
Abstract: Method and computing device for the direct numerical calculation of the field of a physical process, preferably the propagation in the time domain of the electrical and magnetic field of a discretised spatial structure, which is described by the distribution of the relative conductivity, permittivity and permeability and of sources. Electromagnetic fields have principally been calculated hitherto by solving large systems of equations. In this case, account frequently has to be taken of the considerably restricted possibilities of varying the structure. The computing times are so considerable that, for example, the calculation of a transient process in the time domain is not practical. The novel computing device makes this possible in a considerably shorter time and for many different structures. The computing device and method calculate the field vectors for the next time step by means of explicit numerical integration element by element. This necessitates only a few logic combinations with other field vectors. This vastly increases the execution speed in conjunction with a high universality. The computing device described above can be used in the design and planning of electrotechnical objects, apparatuses, devices, systems and in the demonstration and teaching of electromagnetic wave propagation. <IMAGE>

Patent DE-4341220-A1 (DE)
Title: Winding flexible strips pref. magnetic tape on core without flange
Inventor: SCHOLTYSIK BERND DR
IPC: B65H18/00
Filed: 1993-12-03
Abstract: Strip or tape material, e.g. magnetic tape, is wound onto a spool with the speed regulated dynamically to avoid irregular regions being formed where tapering arched gaps termed 'cornets' can occur between layers. The process depends upon a critical speed ratio 'k', defined by k = Nw/Npc = x/y, where Nw is the speed of the winding shaft and Npc is the speed of the tape coil. The ratio of x/y is an integer number.  When the critical ratio is reached a sudden charge is introduced into the speed for specific diameter change. Each winding core sits on a hub driven by a common winding shaft. Windings can be cut into narrower strips and wound to required smaller lengths, known as pancakes.

Abstract: The monitoring takes place between an optical fibre coupler, such as an exchange side subscriber coupler (LT), and a defined, passive, optical interface (PNT1), as part of an optical wide band subscriber linking line (OAL). A rectangular, pseudo-noise, random signal is transmitted together with the information signal from the optical fibre subscriber coupler in the downstream direction over the optical wide band coupling line. A small part of the optical downstream signal is fed back from the passive interface in the upstream direction to the coupler, where it is converted into an electric signal by an optical receiver.

Patent WO-8802811-A1 (WO)
Inventor: DENZ HELMUT
IPC: F02D41/10
Filed: 1987-06-06
Abstract: Procédé pour obtenir des signaux de sortie filtrés d'un appareil de commande électronique dans un moteur à combustion interne. Les signaux de sortie de base obtenus à partir de differents paramètres de fonctionnement sont transmis à des filtres dont les caractéristiques de filtrage sont modifiables en fonction des paramètres de fonctionnement du moteur. On tient compte de phénomènes dynamiques en ce sens que les caractéristiques de filtrage des filtres utilisés sont modifiables en fonction des premières dérivées du signal de l'indicateur de position de l'étrangleur. Une autre possibilité consiste à prévoir, pour le choix des caractéristiques de filtrage, un diagramme caractéristique multidimensionnel et subordonné aux paramètres de fonctionnement. Il est également prévu de former autour des signaux de base calculés une région d'insensibilité dont ne doit pas sortir le signal filtré. Si ce dernier en sort, la caractéristique de filtrage est modifiée de telle manière que le signal filtré rentre à nouveau dans la région d'insensibilité.
