Abstract: In a method and apparatus for producing a composite component, a tubular hollow section blank is placed into a die cavity of a combination tool comprising an inner high-pressure shaping tool and an injection-molding tool. The combination tool is filled with a fluid in such a way that the blank is wetted from the inside by the fluid, and the ends of the combination tool are sealed by two axial molding plugs. The filled blank is then expanded under pressure . The finished hollow section is plastic-coated in the same tool. The hollow section is emptied after shaping in the sealed state, at least until it is no longer dripping, the pressurized fluid being expelled under pressure from the hollow section through at least one discharge channel formed in the axial molding plugs.

Abstract: The invention relates to a device (10) for handling excess paint (20) in a painting booth (12). The device (10) comprises a UV light source (28) by means of which a gas flow (22) containing the excess paint (20) can be exposed to ultraviolet light. The paint cured by means of the UV light is collected and separated from the gas flow (22) in a filter container (36) as paint powder (32). The invention further relates to a corresponding method for handling excess paint (20).

Abstract: A hybrid powertrain system includes torque generative devices to transfer power to an output member. An operator torque request, a rotational direction and speed of the output member, and a signal output from a transmission range selector are monitored. When a change in a direction of intended motion is determined, the powertrain system can change rotational direction of the output member when the speed of the output member is less than a threshold. The powertrain can inhibit a change in the rotational direction of the output member.

Abstract: A height adjustment mechanism for a vehicle seat includes an adjustment parallelogram. The adjustment parallelogram includes a seat frame part, an upper rail and lateral links connecting the seat frame part and the upper rail. A spindle drive can adjust the adjustment parallelogram such that a distance between the seat frame part and the upper rail is changed by changing a length of the spindle drive. The spindle drive connects two obliquely opposing corners of the adjustment parallelogram (1) together in a reinforcing manner.

Abstract: In order to provide better monitoring for the side environment of a vehicle a lighting unit to light up a vehicle environment and a detection unit for detecting an object in the vehicle environment are provided. The lighting unit is automatically switched on if the detection unit has detected an object in the vehicle environment.

Abstract: In a fuel cell system a specific connection and a valve arrangement make it possible for a compressor to supply precompressed air to a fuel cell stack via a waste gas line, said air then leaving the fuel cell stack via a line which is otherwise an air feed line. In this way, a humidifier may be bypassed. This is sensible in particular during a start phase at low ambient temperatures, during which the fuel cell system is intended to warm up without moisture in the fuel cell stack having a negative effect, for instance by freezing. The compressor may be operated both in the start phase or stop phase and during conventional operation by the same mode of operation.

Abstract: Provided is a catalyst composition comprising an intermetallic phase comprising Pt and a metal selected from either Nb or Ta, and a dioxide of the metal. Also provided is a low temperature method for making such compositions that results in the formation of intermetallic phase with small crystallite size and thus greater mass activity. In particular, a Pt3Nb—NbO2 catalyst composition can be prepared that is useful as a fuel cell catalyst and offers a very stable chemical substrate along with good electrode activity and remarkable durability. The use of Pt3Nb—NbO2 can considerably prolong fuel cell lifetime by reducing Pt dissolution levels and subsequent voltage losses. The Pt3Nb—NbO2 can be used in the cathode and/or anode of a fuel cell.

Abstract: An engine is selectively operative in one of a plurality of engine states to transfer torque to an input member of a hybrid transmission. The hybrid transmission is operative to transfer torque between the input member and a torque machine and an output member to generate an output torque in response to an operator torque request. A method for controlling the engine includes monitoring the operator torque request, determining operating power costs associated with a plurality of candidate engine states in response to the operator torque request, determining transition costs for transitioning the engine from a present engine state to each of the candidate engine states, determining stabilization costs for operating the engine in the present engine state and subsequently operating the engine in each of the candidate engine states, and selecting a preferred engine state based upon the operating power costs, the transition costs, and the stabilization costs for the plurality of engine states.
