Abstract: A process for purifying laurolactam by means of integrated connection of distillation and crystallization is provided. The crystallization is performed as a solution or melt crystallization. The process reduces thermal stress applied to the laurolactam stream and improved yields are obtained. Raw materials are recovered and recycled in the production sequence.

Abstract: A power supply system for a vehicle has at least one control unit with two power supply terminals that are each protected against overload by a fuse. The first power supply terminal is connected to a voltage regulator for the microcomputer of the control unit and to the accumulator via the quiescent current switch, while the second power supply terminal is connected to the accumulator via a fuse. The first power supply terminal supplies the microcomputer with energy, while the second power supply terminal actuates one power switch per control unit in order to supply energy to the output stages of an actuator which is operated by the control unit. The on-board vehicle power system control unit activates the quiescent current switch in order to deactivate the microcomputer, while the power switches of the same control unit are supplied with power.

Abstract: In a control system for motor vehicles having a plurality of functional subsystems, such as a passenger compartment controller, a telematics system, a drive controller and a chassis controller, each functional subsystem has a plurality of control devices, and a central databus. Control devices of different subsystems are combined, in accordance with their spatial arrangement in the vehicle, to form local modules and are connected to one another by means of a module bus. Each module bus is connected to the central databus by means of a module interface.

Abstract: Process for the preparation of unsaturated 4,5-allene ketones by reaction of tertiary propargyl alcohols with alkenyl alkyl ethers or ketals in the presence of aliphatic sulfonic acids or sulfonic acid salts.

Abstract: A method and system for routing multi-rate traffic in a communications network determines a first expected admission cost difference that corresponds to admission of the traffic onto a single-link route. If the first expected admission cost difference is less than a pre-determined cost threshold, the network routes the traffic through the single-link route. If the first expected admission cost difference is equal to or greater than the cost threshold, the network determines a second set of expected admission cost differences that corresponds to admission of the traffic onto a set of multi-link routes, and selects the multi-link route that has a minimum expected admission cost difference. If the minimum expected admission cost difference is less than the cost threshold, the network routes the traffic through the selected multi-link route.
