Abstract: A filter arrangement with filter element for purifying a dielectric of a machine for electrical discharge machining has a dielectric inlet with a connector for connecting a dielectric feed connection element of the machine for electrical discharge machining. The filter arrangement has an adapter form fit element that connects detachably to an adapter form fit element of the machine for electrical discharge machining. In a closed position of the adapter form fit elements, the dielectric inlet of the filter arrangement is fluid-tightly connected to the dielectric feed connection element. The adapter form fit elements permit the closed position only in a defined angle position, thereby determining a position of an identification element of the filter arrangement relative to the adapter form fit element of the machine for electrical discharge machining and of a corresponding reading device at the machine for electrical discharge machining relative to the an identification element.

Abstract: A writing, drawing, marking and/or cosmetic device, wherein the device includes at least one shaft and at least one inner body, wherein the at least one shaft is formed from concrete-containing material. The shaft at least partially surrounds the inner body. In the installation position the shaft is secured in an axial direction against axial displacement by a closing cover and a front part and a prestress is formed in the shaft in the axial direction via the closing cover and the front part.

Abstract: A filter element for cleaning an operating liquid of a machine tool is provided with a pressure-stable jacket permitting flow therethrough. A filter medium is arranged in the pressure-stable jacket. A first end disc and a second end disc are seal-tightly connected to opposite ends of the filter medium. The filter medium surrounds an inner raw-side cavity. The pressure-stable jacket surrounds the filter medium and is connected fixedly to the first and second end discs. The first end disc has an inlet opening for the operating liquid. The second end disc has a drainage opening provided with a releasable closure element that closes the drainage opening.

Abstract: For fault detection in a switch system including multiple switches, for a respective switch its operating data are acquired and transmitted to a central control. For a respective first switch of the switch system, a deviation of an operating behavior of the first switch from a set behavior is determined by the central control on the basis of its operating data. If there is a deviation, operating data of the first switch are compared with operating data of other, second switches of the switch system and, depending on that, a second switch with similar operating data is selected.

Abstract: A method and an apparatus for identifying faults in a computer-aided manner for a technical system including a switch and a switch drive is provided. A fault or a disruption in the switch and/or in the switch drive is detected by capturing a temporal profile of a measurement variable of the switch drive. A simulation model is provided for the technical system and a fault situation is set by means of setting values of the simulation model, wherein the setting values are assigned to the fault situation. The technical system is simulated by means of the simulation model, wherein a simulated temporal profile of the measurement variable is captured. The simulated temporal profile is compared with the temporal profile of the measurement variable of the switch drive, wherein the fault situation is assigned to the detected fault on the basis of the comparison.

Abstract: This disclosure relates to navigating a vehicle based on predicted trajectories of other vehicles. Systems, methods, and computer-program products consistent with the disclosure perform operations including receiving location information of other vehicles. The operations also include comparing the location information of the other vehicles with an intended trajectory information of the vehicle. The operations further include determining that interference exists based on the comparing. Additionally, the operations include determining a modification to the intended trajectory information of the vehicle that resolves the interference with one of the other vehicles. Moreover, the operations include presenting the modification to the intended trajectory information of the vehicle to an operator of the vehicle. Further, the operations include modifying the intended trajectory using the modification.

Abstract: The invention concerns a tool for machining of materials, specifically a grinding tool, which has a substantially rotationally symmetrical shape with respect to a rotation axis (R), the tool comprising an outer shell centered about the rotation axis and defining an internal space therein, wherein at least a part of a surface of the outer shell is provided with an abrasive coating or component, wherein the outer shell encases an internal skeleton structure in the internal space, the internal skeleton being integral with the outer shell and defining void volumes in the internal space thereby establishing material and void volumes of the internal space, and wherein the material to void ratio M/V is distributed substantially identically along each radius (r) centered around the rotation axis (R) and its corresponding symmetrical radius (r?). The invention also concerns a method for producing such tool.

Abstract: A plumbing system includes a tub having a drain fixture lodged within a floor drain opening. The drain fixture comprises a body member beneath the floor and a drain cap member inserted into an exposed open inlet of the body member. The body member has a passageway extending between the open inlet and a downstream open outlet in communication with a sewer. A pipe connected to the body member between the inlet and outlet has one end in communication with the passageway and another end in communication with an overflow opening in the tub above the drain opening to vent the passageway. The drain cap member moves between a first position allowing liquid to flow through the passageway and a second position preventing the flow of liquid through the passageway.

Abstract: A method operates a railway safety system having at least one trackside device while taking into account a measured velocity value recorded when the rail vehicle drives into a switch-on section of the railway safety system. In order to minimize the closing times for a level crossing by such a method, the measured velocity value is used as the basis for checking whether a correction time for forwarding a signal from the one trackside device to an associated railway safety assembly is to be set according to the measured velocity value when the rail vehicle drives into the switch-on section. Thereafter, a set correction time is checked to determine if the set correction time should remain effective according to at least one further influencing variable of the rail vehicle that determines the travel time. A railway safety system for carrying out the method is also provided.
