Maximum HF current is initially introduced into tissue at a pre-specified maximum coagulation voltage. In this initial state, the tissue behaves in accordance with Ohm's law and can take up the maximum energy per unit of time. After the tissue has changed from an initial state to a state in which the tissue impedance or resistance is voltage-dependent, the HF parameters are selected such that the maximum possible energy input per unit of time is set.

A process for making soda-lime glass includes calcinating calcium carbonate in solid phase and at elevated temperature to form calcium oxide and release gases such as carbon dioxide. Sodium silicate glass is formed separately in liquid phase while releasing gaseous reaction products. The calcium oxide and the sodium silicate glass intermediate products are mixed in liquid phase to form a soda-lime glass melt. Formation of sodium silicate glass as an intermediate product before mixing with the calcium oxide has the advantage of promoting release of gaseous reaction products in the sodium silicate due at least in part to the relatively low viscosity of the sodium silicate glass. The calcination step and / or the sodium silicate-forming step and / or the final mixing step can be carried out under reduced pressure further to promote release of gases and reduce bubble formation.

In the invention, a method combining three-stage variable speed with local energy compensation is adopted for correcting a warping deformation, and the energy coarse adjustment is carried out by adopting a three-section variable speed mode to adopt a low speed to ensure higher energy input at the section position with small bending angle and high bending angle adopting high speed to ensure lower energy input; the energy compensation method comprises the following steps of: carrying out energy compensation on a segment position with small bending angle by scanning a local area with small bending angle for lesser times after the local energy compensation mode is processed; and the combination of the two aspects can effectively reduce the bending amount in the laser bending processof the metal sheet and meet the technical requirements. The method can be applied to the field of metal sheet forming with high angle precision required by laser non-die bending processing.

A method for determining the temperature of an electrically heatable catalytic converter having an electric heating element that includes a heating resistor, the electrical resistance of which changes as a function of the component temperature of the electrically heatable catalytic converter. This resistance is determined from the current intensity and the voltage at the electrically heatable catalytic converter, and is used to determine the component temperature of the catalytic converter, based on a characteristic curve stored in the control unit. The energization of the heating resistor for determining the component temperature takes place in each case for only a short time in order to minimize the energy input into the heating resistor and thus avoid overheating of the heating resistor. In addition, by use of the short time interval, the aim is to minimize the energy requirements for determining the component temperature of the electrically heatable catalytic converter.
