Abstract: A method for producing bearing components includes providing a first bearing component, a second bearing component, a first production line, and a second production line. The first production line has a first grinding machine, a first honing machine, a first measuring unit, and a first conveyor unit. The second production line has a second grinding machine, a second honing machine, and a second conveyor unit. The method also includes grinding and honing the first bearing component, measuring a first dimension of the first bearing component, grinding and honing the second bearing component, and combining the first bearing component and the second bearing component to form a roller bearing or a slide bearing. The first production line and the second production line are operated in a synchronized manner such that the second grinding machine or the second honing machine is operated under closed-loop control using the first dimension.

Abstract: A method for operating and controlling a machine installation by means of a graphical development environment (1), with which a controller on the machine side having programmable hardware modules (13, 14) situated there is graphically displayed, and via user-side inputs a programming sequence (24) is created in the development environment (1) and is supplied to the hardware modules (13, 14). According to the invention, an embedded web server (2) and an embedded browser (4) that communicates with same are integrated into the development environment (1), and the programming sequence (24) created in the development environment (1) is supplied to a field bus master (8), which supplies the programming sequence (24) via a field bus (10) to the station head (12) of a hardware station (11) in which the hardware modules (13, 14) which are programmable with the programming sequence (24) are situated and communicate with the station head (12).

Abstract: A method for operating an auto-darkening welding filter for protecting a welder's eye in the course of a pulse mode welding process. During the pulse mode welding process at least a first time interval with strong light emission and a second time interval with reduced and/or negligible light emission are repeated with a repetition rate, and a point in time of a beginning of the first time interval is associated with a raising edge event. The method includes the step of darkening the auto-darkening welding filter to a first darkening level at a point in time of the raising edge event that is associated with a next first time interval.

Abstract: A rotary table mounting and drive device (1), including a rotary table (3) which is rotatably mounted on a frame (2) and for the mounting of which an axial/radial rolling bearing arrangement (4) and an active magnetic bearing arrangement (5) are provided, has an electric direct drive (19) which is preferably a torque motor having a rotor (20) rigidly connected to the rotary table (3) and a stator (21) rigidly connected to the frame (2).

Abstract: A pivot bearing device, particularly for a rotating circular table of a machine tool is provided, and includes a first device part, which is to be connected to an element that is to be rotatably mounted, particularly to the circular table, and a second fixed device part. The device parts are connected via at least one antifriction bearing upon which an axial force acts. A magnet device (21), which acts between the first and second device parts (2, 3), is provided for generating a compensating force (Fk) oriented in essentially the opposite direction to the axial force (Fa).

Abstract: The invention relates to an electrical power supply system for feeding electrical loads, having at least two electrical energy stores, a circuit for connecting the electrical energy stores to an electrical d.c. network with loads and at least one power generator, wherein each energy store can be connected to the d.c. network by activating switching elements by means of d.c. transformers.

Abstract: An electrical rechargeable battery with an electronic functional monitoring circuit integrated in the rechargeable battery container. The rechargeable battery contains an apparatus for measuring battery voltage, an apparatus for measuring battery temperature and an apparatus which detects the current direction by means of a measurement apparatus on the battery pole stem. The electronic circuit contains a microprocessor which uses the input variables to calculate the state of charge and/or the serviceability of the rechargeable battery, and the calculated output values can be passed on via a communication apparatus. A visual indicator is arranged on the rechargeable battery container, can be actuated via the communication apparatus, and indicates information about the state of charge and/or serviceability.
