摘要:
A method of controlling the energization of a heating device for the regeneration of a particle filter disposed in the exhaust duct of an internal combustion engine, particularly a Diesel engine, wherein a measure for the soot charge state of the particle filter the exhaust gas back pressure is determined while the engine is preferably idling, the exhaust gas recirculation is switched off, and predetermined conditions are present in the exhaust gas duct upstream of the particle filter, and then an exhaust gas back pressure signal is compared with a threshold value indicating a soot charge sufficient for the initiation of a regeneration of the particle filter and the heating device is enabled for the initiation of the regeneration procedure if the exhaust gas back pressure signal is greater than the threshold value.

A tensioning device of a surgical retractor has a tensioning section for applying a tensile force to a tool that is to be arranged thereon, and a holding bar fixed in position relative to the tensioning section, and also a locking device. The locking device is provided between the holding bar and the tensioning section and has a releasable locking function counter to the direction of the tensile force. The tensioning device can be operated comfortably, with minimal force being applied, is optimally accessible and takes up only a small overall volume. This is made possible by the fact that the locking device is configured as a linear ratchet or linear feed mechanism and that the feed mechanism has an actuating lever and an unlocking device.

A quick-action tensioning clip of a wound retractor, with at least one braceable seat for at least one holding arm and/or for a joint ball of a holding arm, is made available which can be operated safely, easily and quickly and which requires only low operating forces and at the same time safely and permanently generates high clamping forces, this being achieved by the fact that, in order to generate the tensioning force, it is equipped with a toggle catch composed of two joint levers which are connected to each other via a connecting joint and which, at their free ends, are articulated via attachment joints on component parts of the quick-action tensioning clip that can be mechanically moved away from or towards one another.

A method for joining sinter metal elements comprising a carrier sheet having openings filled with a sinter metal for the construction of a sinter metal filter element or sinter metal filter body is disclosed. At least two sinter metal elements having pores for the passage of a fluid to be filtered are disposed adjacent one another and joined along an end section thereof by first introducing fine particles into the pores of the sinter metal elements in an area adjacent to the end sections of the sinter metal elements to be joined, so as to close the pores in that area, and the end sections of the sinter metal filter elements are then joined by heating with a joining material which, upon heating melts and enters the pores of the end section of the sinter metal elements but not the blocked pores in the adjacent area. A filter body produced therefrom is also disclosed.

摘要:
In a device for supplying ammonia (NH3) to a reduction catalytic converter arranged in an exhaust system of an internal combustion engine comprising a container for storing a precursor body capable of generating ammonia when heated by a heating device disposed in the container for the thermolytic decomposition of the precursor material, the heating device includes a heating surface arranged adjacent the precursor body and means are provided for biasing the precursor material body in firm contact with the heating device surface for direct heat transfer to the precursor body, and the heating device is connected to a control unit for controlling the energization of the heating device depending on the NH3 requirements of the reduction catalytic convertor.
