Abstract: A pulse-width rectifier for operating an electric machine in motor operating mode or in generator operating mode, includes a terminal for a control device that communicates with the pulse-width rectifier via a data connection. In order to safeguard the supply of energy in the case of a disturbance in the data transmission between the control device and the pulse-width rectifier, the pulse-width rectifier is constructed such that it automatically switches into an emergency generator operating mode in which it produces at its direct-voltage output a prespecified power with which it is possible to maintain at least an emergency operation of electrical consumers.

Abstract: A method for controlling a motor vehicle drive, in particular a hybrid drive, is provided, the motor vehicle drive having at least two individual motors. In a first method step, at least one total setpoint torque is calculated. In a second step, the at least one total setpoint torque is split into at least two individual setpoint torques of the at least two individual motors. Subsequently, in a first individual torque comparison step, the sum of the at least two individual setpoint torques is compared with the total setpoint torque. In the event of a difference by more than a predefined tolerance value, a limitation step is initiated. In this limitation step, the at least two individual setpoint torques are each multiplied by a limiting factor to generate at least two limited individual setpoint torques.

Abstract: A shirt-smoothing device includes a lower part and an inflatable body fixed thereon. Because the inflatable body must be at least the same size as the shirt to be smoothed, the device has considerable height, however, the rigid components in the area of the inflatable body are lowerable to handle the device more easily and, more particularly, to stow it away easily. An internally disposed supporting frame and a button strip tensioner disposed in front of the inflatable body can be lowered after use into the lower part, whereby the inflatable body, which is exclusively connected to the supporting frame at the top becomes folded. The same applies to flexible inflatable support bodied and support nets disposed between the inflatable body and the supporting frame. The storage space required for the shirt smoothing device can be substantially reduced by the invention and the handling and storage thereof simplified.

Abstract: A rotary fluid-control valve for controlling fluid flow has a cylindrical valve chamber, a dove-tail shaped valve body mounted rotatably in the valve chamber and movable between an open position and a closed position, and four fluid passages extending from the valve chamber. The passages are arranged essentially parallel with respect to one another and the valve body is pivotally connected to the valve chamber with a pivot pin extending in the axial direction of the valve chamber. The passages extend perpendicular to the pivot pin. The valve chamber has a convex section that, when the valve body is rotated out of the closed position, causes an asymptotic rise in the throughflow quantity. A stop or pressure equalizing projection projects into the valve chamber and is dimensioned so that a pressure drop in the closed position of the valve body corresponds to a pressure drop of the radiator in the open position of the valve body.

Abstract: A device and method for controlling air conduction in a vehicle includes an air conduction element. The air conduction element is controlled as a function of the moisture in the vehicle interior, intermediate positions of the air conduction element being possible between a maximum proportion of circulating air and a maximum proportion of fresh air. In this way, the proportion of fresh air is increased only gradually when there is a high pollution impact if the interior moisture does not exceed a maximum moisture value .PHI..sub.max. Control of the moisture in the vehicle interior increases the comfort of the vehicle occupants. A circulating-air dryer makes it possible, in principle, to continue in circulating-air operation for an unlimited period.
