Abstract: Various examples of the disclosure pertain to determining a set of calendar aging values of a test cell of a rechargeable battery, e.g., LIBs. The set of calendar aging values of the test cell of the rechargeable battery corresponds to a set of Temperature-State of Charge (T-SOC) value pairs. The set of calendar aging values of the test cell of the rechargeable battery is determined based on a battery-generic reference model for calendar aging of a (specific or random) battery cell and on a further set of calendar aging values of the test cell of the rechargeable battery. The further set of calendar aging values is obtained/derived from measurements of the test cell of the rechargeable battery and corresponds to a further set of T-SOC value pairs.

Abstract: A tool system includes a machine-proximal shank configured to be introduced into a driven tool receptacle and containing a device for transferring a rotating movement to be picked up from the driven tool receptacle. A tool-proximal shank is configured as a tool holder or to have a tool holder releasably connected thereto. A gear mechanism disposed between the machine-proximal shank and the tool-proximal shank is configured to transfer a rotating movement transmitted by the device in a reduced manner to the tool-proximal shank. At least one insert seat configured on the tool holder for receiving an interchangeable cutting insert is provided on an end face of the tool holder extending transversely to a longitudinal axis of the tool holder. A method for machining a workpiece is also provided.

Abstract: A cutting tool that is assembled and ready for delivery has at least one actual dimension relating to a physical configuration of the cutting tool and being relevant for a cutting process carried out by the cutting tool. The cutting tool that is assembled and ready for delivery is assigned at least one information source that is readable by a user or a data processing system. The information source provides or encodes information relating to a deviation of the at least one actual dimension from a target dimension or the actual dimension itself. A holder for a cutting tool and a machine tool having a cutting tool are also provided.

Abstract: A press arrangement and a method for producing and processing compacts from powder material include a controller, a press frame, a pressing unit being disposed on the press frame for pressing the compact and having a die with a cavity for receiving powder material, at least two punches which, together with the cavity, provide a mold for a compact and at least one drive unit for moving at least one punch relative to the other punch along a pressing axis. A further processing module has at least one processing unit for machining a compact by metal cutting. The controller at least partially ejects or removes a compact from the die after pressing and, after the ejection holds the compact clamped between the punches. The controller uses the processing unit to process a compact being at least partially ejected from the die and held clamped between the punches.

Abstract: A mold for producing a green compact using powder metallurgy processes has an upper punch and a lower punch which are movable along a common press axis and a die body with a charging chute for receiving powder material. The die body has an upper region in which the upper punch is movably guided along the press axis in the charging chute, and a lower region in which the lower punch is movably guided along the press axis in the charging chute. Two cross slides realize a forming region which determines the lateral outside contour of the green compact, and are arranged on the die body so as to be displaceable in a direction which deviates from the press axis. The two cross slides only move into contact with one another when the two cross slides are arranged in their respective end position.

Abstract: A hard-material threaded connection includes a structural part, which has a hard material and a first threaded portion formed in the hard material, and a component having higher elasticity that has a second threaded portion cooperating with the first threaded portion. The first threaded portion and the second threaded portion have a different thread pitch.

Abstract: A smoke detector system that includes an airflow barrier installed between a detector base unit and a mounting surface to ensure there is separation between the detector base unit and the mounting surface. The barrier isolates and seals the smoke detector to prevent the formation of condensation in or around the smoke detector. The barrier further includes a cavity that can collect condensation if condensation does occur. The condensation is then directed to a channel that extends around the periphery of the airflow barrier. Additionally, the channel includes weep holes so that condensation has a means to exit the detector.

In one embodiment, one side of a plastic layer of a multi-layered optical disc is exposed to a plurality of non-reactive ions, an adhesive material is applied to the side of the plastic layer that was exposed to the plurality of ions, and a second layer of the optical disc is secured to the adhesive material. In another embodiment, a plurality of ions is formed by directing gas molecules through an electric field, and at least 25% of the width of the plastic layer of the multi-layered optical disc is exposed to the plurality of ions at about the same time. The plastic layer is positioned so that the ions contact the plastic layer while the ions still have a charge, and the disc is moved so that at least 25% of the surface of the plastic layer is exposed to the plurality of ions.
