Abstract: A method for mounting and aligning a guide rail in an elevator shaft of an elevator system, which elevator shaft primarily extends in a main extension direction, includes at least the following steps: securing a rail bracket base to a shaft wall of the elevator shaft; applying a mark to the rail bracket base; aligning the guide rail in relation to the mark; and securing the guide rail to the shaft wall using the rail bracket base. The alignment of the guide rail is carried out by an alignment device that includes an abutment part and a location device.

Abstract: A textile machine includes a plurality of workstations adjacently situated in a longitudinal direction of the textile machine, the workstations combined to form multiple sections wherein each section includes one or more of the workstations. A plurality of electrical supply units supply electrical energy to the workstations, wherein one of the electrical supply units is assigned to each section or to each workstation. A cooling arrangement includes at least one coolant circuit configured with the electrical supply units such that waste heat generated by one or more of the electrical supply units is absorbed by a coolant within the coolant circuit and transported to a common discharge area of the textile machine.

Abstract: The disclosure relates to a motor vehicle having an electric drive, wherein the motor vehicle has an HV primary energy storage device to supply energy to the electric drive, wherein the motor vehicle has at least one predetermined mounting area, which is formed such that an HV alternative energy storage device can be mounted in the mounting area and the motor vehicle is formed with an access opening through which the HV alternative energy storage device can be placed in the mounting area and through which an HV alternative energy storage device mounted in the mounting area can be removed from the motor vehicle.

Abstract: A textile machine (1), in particular a rotor spinning machine, comprising a plurality of adjacently situated workstations, in particular spinning and/or winding stations, which are combined to form multiple sections (2a-2f). The textile machine (1) further comprises multiple electrical supply units (3a-3f), with the aid of which the workstations and/or the sections (2a-2f) can be supplied with electrical energy, and a cooling arrangement (4) including at least one coolant circuit (16a-16c), with the aid of which waste heat of the electrical supply units (3a-3f) can be absorbed and transported to a discharge area (5) of the textile machine (1). The cooling arrangement (4) is designed in such a way that the waste heat of several of the electrical supply units (3a-3f) can be transported to a common discharge area (5) of the textile machine (1) with the aid of the at least one coolant circuit (16a-16c).
