Abstract: A two-stage exhaust gas turbocharging device for an internal combustion engine includes a high-pressure stage, and a low-pressure stage. The high-pressure stage and the low-pressure stage are connected via exhaust-gas lines and fresh-air lines in a gas-conducting manner. An exhaust gas of the internal combustion engine can flow first through the high-pressure turbines and then the low-pressure turbines and wherein fresh air are conveyable first through the low-pressure compressors and then through the high-pressure compressors in the direction of the internal combustion engine. The high-pressure turbines are connected to the low-pressure turbines at least in sections via a common exhaust-gas line and the low-pressure compressors to the high-pressure compressors at least in sections via a common fresh-air line.

Abstract: A two-stage exhaust gas turbocharger for an internal-combustion engine having an exhaust manifold is provided. In the exhaust gas flow direction a first high-pressure turbocharger and a second high-pressure turbocharger are arranged parallel to one another and a low-pressure turbocharger is arranged in series behind the latter. The two high-pressure turbine housings can be arranged on the exhaust manifold on one side and the low-pressure turbine housing can be arranged on the exhaust manifold on the other side. The exhaust gas coming from the high-pressure turbine housings is guided through a flow duct in or on the exhaust manifold to the low-pressure turbine housing. By way of this construction of the two-stage exhaust gas turbocharging, a compact construction is achieved resulting in cost savings.

Abstract: Wipes treated with organometallic compounds used in combination with organic acids in kit form, particularly organophosphorus acid, are disclosed. The kits can be used to treat various surfaces to alter the physical properties of the surfaces.

Abstract: An organometallic coating deposited from a metal alkoxide composition under conditions sufficient to form a polymeric metal oxide coating with unreacted alkoxide and hydroxyl groups is disclosed. Also disclosed are substrates coated with the organometallic coating and a method for applying the organometallic coating to a substrate.

Abstract: A process for applying an organophosphorus-based layer on a substrate, utilizing a solution of an at least partially amine-neutralized organophosphorus acid, is disclosed.

Abstract: Compositions for treating glass fibers in which the composition comprises an organophosphorus acid or a derivative thereof are disclosed. Energy is applied to the glass fibers to bond the organophosphorus acid or derivative to the glass fibers.

Abstract: A telecommunications network such as an ATM, Frame Relay or packet based network will be better managed by identifying nodes through which a virtual connection is routed between two end nodes. A new method of tracing the nodes on the route includes sending trace cells downstream of a monitoring node toward one or both end nodes. Each downstream node either loops back a trace cell identifying itself to the monitoring node or forwards the trace cell further. A plurality of trace cells sent along the route identify nodes located thereon. In one embodiment, the trace cell is an extension of the ATM FMOAM cell (ATM Fault Management OAM cell) specified for loopback functions.
