摘要:
A drive unit is in working connection with a power takeoff by way of a wrap spring, which has a predetermined number of turns between its two ends and which serves as a load torque interlock. The wrap spring has a first actuating area assigned to a selected direction of rotation on at least one of its two ends and a second actuating area assigned to the opposite direction of rotation, where the first actuating area can be brought into nonrotatable working connection with the drive unit and the second actuating area into nonrotatable working connection with the power takeoff. By the application of a drive torque produced by the drive unit on the first actuating area, a first change in the diameter of the turns in the direction away from a braking device can be obtained, with the result that the frictional connection between the turns and the braking device is at least weakened. By the absorption of a restoring torque which originates from the power takeoff and acts in the opposite direction of rotation on the second actuating area after the drive has been turned off, a second change in the diameter of the turns in the direction toward the braking device can be obtained, with the result that the frictional connection between the turns and the braking device is increased.

A device which is used to guide cables or wires through walls. The device includes a maintaining device which is connected to two or more cable maintaining elements that surround, in a frame-like manner, a mounting area which includes a through-opening, and the cable maintaining elements are arranged in the region of the through-openings. According to this invention, the mounting area has a matrix-form and includes at least two mounting lines and at least two mounting gaps which enable the mounting area to be equipped in a simple and easy manner. The mounting lines and the mounting gaps predefine, respectively, a constant modular dimension, and the cable maintaining elements are dimensioned with respect to the width and the longitudinal extension in the direction of the mounting line and direction of the mounting gap, so that the width and the length correspond to a multiple whole number of the modular dimension.

A portable spray apparatus (1) is provided to selectively discharge liquid spray medium and solid dust medium with a blower airflow (7) generated by a blower (6). An adaptor (8) is provided which has at least a channel section (9) of a liquids channel (10) for the liquid spray medium and a channel section (11) of a solids channel (12) for the solid dust medium. The adaptor (8) is releasably connected to a supply vessel (4). The liquids channel (10) and the solids channel (12) open into the blower airflow (7). Various built-in positions of the supply vessel (4) and of the adaptor (8) are freely selectable relative to each other and to the blower unit (3) by the operator. In one built-in position, the liquids channel (10) is connected via its channel section (9) to an interior space (13) of the supply vessel (4) and, in another built-in position, the solids channel (12) is connected to this interior space (13) via the channel section (11) thereof.

The invention relates to a fuel cell system including a first heat exchanger via which cathode feed air can be supplied to a fuel cell or fuel cell stack and to which a mixture of afterburner exhaust gas of an afterburner and cathode exhaust air having materialized in the fuel cell or fuel cell stack can be supplied for heat exchange between the cathode feed air and the mixture via the first heat exchanger. In accordance with the invention it is provided for that a second heat exchanger is provided via which the cathode feed air can be supplied from the first heat exchanger to the fuel cell or fuel cell stack and via which the afterburner exhaust gas can be supplied to the first heat exchanger to form the mixture, in thus achieving a heat exchange between the afterburner exhaust gas and the cathode feed air.

The invention relates to a method for damping vibrations on chassis bearings of motor vehicles, and a device for implementing the process. A process and a device are to be presented with which outstanding vibration damping and vibration isolation and noise insulation can be achieved over a wide frequency range with consideration of the driving states and roadway conditions which occur in motor vehicles. For this purpose it is proposed that the driving state of the motor vehicle and/or the roadway conditions are detected by way of sensors and that the at least one chassis bearing is modified to different characteristics to change its stiffness and/or damping depending on the detected parameters. The device is formed with sensors for detecting the driving state of the motor vehicle and for roadway conditions, with an electronic control device for processing the acquired signals and for selection of various controllable characteristics and at least one chassis bearing, the stiffness and/or damping of which can be modified.
