Abstract: A method for reducing the speed of propagation of a crack in a metal substrate by means of laser heat treatment can include heating the metal substrate with a laser heat treatment at one or more crack ends, wherein the laser beam is guided over the substrate surface so that it defines the form of an oval, an arc or a curve. Alternatively, the substrate can be treated by means of laser heat treatment before a crack arises. For example, areas at risk of cracking are identified in a metal substrate and the metal substrate is then heated by means of laser heat treatment in these areas, wherein the laser beam is guided over the substrate surface so that it defines the form of an oval, an arc or a curve. Also disclosed herein are metal substrates produced by the method and the use thereof.

Abstract: An apparatus is provided for delivering a substance containing hydrocarbons from a reservoir. The reservoir can be subjected to thermal energy in order to reduce the viscosity of the substance. The apparatus includes at least one conductor loop for inductively applying current as an electric/electromagnetic heater. A conductor of the conductor loop is surrounded in at least one section by a liquid-carrying conduit. The liquid-carrying conduit is perforated such that when a liquid is supplied the liquid penetrates into the reservoir from the liquid-carrying conduit via a perforation.

Abstract: A method for diagnosing a frequency converter is used for a frequency converter having a positive and negative DC link voltage which is applied via bridges of switching elements in an alternating sequence to phases of a motor. Pulse width modulation (PWM) signals drive the switching elements for a respective one of the phases and current sensors capture phase currents. In a step a), PWM signals are applied as test patterns to the switching elements. In a step b), sensor signals of the current current sensors are picked up. In a step c), the sensor signals are evaluated by ascertaining a presence of the DC link voltage upon a displacement current being recognized in the sensor signals.

Abstract: A device stores electric energy, in particular for the traction supply of a rail vehicle. The device has a plurality of chargeable storage cells with cell poles, a cooling body that is in thermal contact with the storage cells, and a plurality of bridge members, by way of which two of the plurality of storage cells are in electric contact. Accordingly, at least some of the bridge members contact the storage cells on the sides thereof facing the cooling body. A bridge member contains a connecting web having two recesses and two connecting parts, each being introduced into one of the recesses. Each connecting part is connected to a cell pole of a storage cell to be contacted. The connecting parts are fixed non-rotatably and non-displaceably in a connecting web by a releasable tensioning device. Thus the efficiency and service life of the energy storage device can be increased by reducing the thermal resistance between the storage cells and the cooling body.
