Abstract: An exhaust gas treatment system for the purpose of reducing the harmful substances present in the exhaust gas of combustion engines, particularly diesel engines, has a gas- and liquid-tight housing with at least one inlet and at least one outlet. Gas guide elements are arranged in the housing, and the housing encloses at least one chamber in which is contained a catalyst material and/or a particle filter material. The gas guide elements have spark-catching and/or spark-extinguishing elements.

Abstract: A braking device (2) for braking a lift car which moves relative to a lift shaft, having at least one braking module (6) which is provided in order to interact with a device, and having a catch (4) which can be adjusted between two operating positions (36, 360, 38), wherein the catch (4), in a first operating position (36, 360), is connected to the at least one braking module (6) such that the catch (4) transmits a release force (22) to the at least one braking module (6), and wherein the catch (4), in a second operating position (38), is separated from the at least one braking module (6), and the at least one braking module (6) is therefore in contact with the device.
