Abstract: A measurement or protective device has a terminal for establishing a connection to a data bus. A control device determine the mode of operation of the measurement or protective device, and the mode of operation can be changed from the outside using the terminal. The novel device enables evaluation operations, in particular testing operations, from the outside in an even simpler manner than before. The control device is configured in such a manner that it can operate at least two software modules in parallel and independently of one another. One of the software modules is an operating module which determines the measurement or protective mode of operation of the device, and at least one additional software module has another function. The control device has at least one software interface to which the additional software module can be coupled, in terms of software, from the outside using the terminal.

Abstract: Elongate cylinder head gasket for a multicylinder engine comprising a chain case, with a chain case part which is to be mounted following clamping of the gasket and is guided for displacement parallel to the plane of the gasket; in order that the cylinder head gasket will not be damaged at its one narrow side when inserting this chain case part, the outer edge area of a center narrow side portion on this narrow side is bent out of the plane of the gasket, more particularly, in a direction which points away from the chain case part which is to be inserted.

Abstract: A metallic cylinder head gasket for an internal combustion engine having cylinder liners, the gasket comprising at least one cover plate which has a plurality of openings, commensurate with the combustion chambers of an internal combustion engine. The gasket has beads which extend around the openings, the beads being arranged at a distance from the edges of the openings. An annular upward extension is arranged concentrically with respect to each bead and serves as an upward extension of the combustion space and as a deformation limiter for the bead. The gasket is provided with at least one flat carrier plate. The upward extensions are formed by rings which are supported by the liner collars.

Abstract: Connecting points of fully solid material insulated conductors in the form of a fully solid material insulated hollow body, which is provided on the inside with a shield and in which at least a pair of current conductor inputs are arranged, is intended preferably for application in the high voltage switching and distribution equipments. The object and aim of the invention is to provide a coupling point which enables the increase of the operational reliability, the reduction of the complexity of assembly, servicing and repairing operations, as well as the coupling of offset or branching-off current conductors.

Abstract: A vacuum switching apparatus having a pair of terminal members extending from a housing made from a fully solid insulating material such as epoxy resin, and forming an outer housing for the vacuum switching apparatus, into which a vacuum switching chamber is placed housing a fixed and a movable contact member, the movable contact member extending through metallic bellows into a sliding contact and into the coupling terminal, wherein a pair of control electrodes each being conductively coupled to a different one of the terminal members is embedded into the fully solid insulating housing and lying at the potential of the respective terminal members, a further control electrode placed in the insulating housing and lying in a region so that it will assume an intermediate potential between the terminal potentials and the ground potential and wherein further a grounded outer metallic casing encloses insulating housing.

Abstract: In controlled systems with dead time, particularly converter current controls, the reference value is fed directly to the final control element providing anticipatory control and, in addition is fed to the reference input of the controller through a dead time simulator. In accordance with a further feature, the difference between the input signal and the output signal of the dead time simulator can be added into the final control element as an additional control variable to compensate for inertia of the controlled system.
