Abstract: A self-propelled floor processing device with an evaluation unit, which is designed to navigate the floor processing device within an environment based on an area map and, during a movement, to determine a behavior parameter of the floor processing device and a movement path of the floor processing device. The evaluation unit is set up to analyze the behavior parameter and movement path, automatically determine a no-go area which the floor processing device must not traverse depending on the result of the analysis, and enter the determined no-go area in the area map or change a no-go area already entered in the area map.

Abstract: A multi-stage integrally geared compressor includes a first process stage, a second process stage and a gearbox for coupling the two process stages to each other at different rotational speeds. The gearbox further couples a compressor drive shaft to the two process stages at a further rotational speed, which is different from the rotational speeds of the process stages.

Abstract: The invention relative to an exhaust gas system (10) for a spark-ignition internal combustion engine (12), comprising an HC adsorber (22) as well as, downstream from it, a catalytic converter (20) designed at least to convert hydrocarbons (HC), and it also relates to a method for operating an exhaust gas system (10). It is provided that a burner device (30) which is operated or can be operated with air and fuel is installed downstream from the HC adsorber (22) and upstream from the catalytic converter (20).

Abstract: A method is provided where carbon dioxide is compressed in a multi-stage geared compressor using a substantially isothermic process to a pressure which lies above the pressure of the critical point of carbon dioxide. The carbon dioxide is subsequently cooled to ambient temperature in a cooling device and then compressed to a predefined final pressure in a pump device.

Abstract: A connecting arrangement includes at least first and second housings in which at least one conductor of a first cable can be electrically connected to at least one conductor of a second cable fed via a cable receiver. At least one piercing element is electrically connected to the second cable and configured to be inserted transversely into the conductor of the first cable. The cable receiver is constructed as an integral unit with the second housing and the piercing element. A sealing element configured to seal a piercing point of the piercing element is arranged on an inner side of the second housing and the cable receiver is disposed on an outer side of the second housing. The sealing element and the cable receiver are formed in one piece through the second housing.
