Abstract: A gas sensor is described that includes a planar carrier membrane; a gas-sensitive layer on the carrier membrane; a first and at least a second electrode, which each lie on the gas-sensitive layer in an electrically conductive manner; and a first electric supply line to the first electrode and a second electric supply line to the second electrode. The second electrode lies radially outside the first electrode, and the first supply line is insulated with respect to the gas-sensitive layer.

Abstract: A continuously variable transmission for transmitting torque with at least one input shaft introducing torque into the continuously variable transmission, with at least one further shaft, to which the torque is to be transmitted, and a force-transmitting endless element, which has a non-positive connection to the at least one input shaft and the at least one further shaft. A connection between either the at least one input shaft or the at least one further shaft and the force-transmitting endless element is provided by a rotary disk (10) around which the force-transmitting endless element is wrapped. The continuously variable transmission is characterized in that the rotary disk (10) has a radius (20), which is dependent functionally on a rotational angle and a certain mean radius. The invention further relates to an out-of-round rotary disk (10) for providing a non-positive connection.

Abstract: A rotating disk is provided, which can rotate by a rotational angle about a rotational axis (12) and has a number of teeth (20) arranged on a periphery of the rotating disk (10) and tooth spaces (22) located between the teeth, through whose middle runs a tooth-space middle line (30), and the rotating disk (10) has a periodically changing tooth-space geometry. The rotating disk (10) has a tip circle radius (24) that is constant. In addition, a drive device and a belt drive with a rotating disk (10) are provided.

Abstract: A rotary disk which is rotatable through a rotation angle around a rotation axis, which includes a rotary disk contour having at least one elevation and a predetermined number of teeth arranged on the rotary disk contour with respective midpoints is provided. The midpoints of respective adjacent teeth having a predetermined spacing, a rotary disk radius which depends functionally on the angle of rotation in an average radius, and a rotary disk wrapping curve resulting therefrom, the average radius being chosen such that an arc length running around the rotary disk wrapping curve is equal to the product of the predetermined spacing of the midpoints of adjacent teeth and the number of teeth. A corresponding method for designing at least one rotary disk for a timing control drive, rotatable through a rotation angle around a rotation axis, is also provided.

Abstract: A process for optimized design of a tension means drive having at least one non-circular pulley on an internal combustion engine, in which the pulley is controlled in position such that upon dynamic superposition of an excitation of the tension means drive during driving resulting from the pulley shape with at least one further excitation of the tension means drive, a specific overall excitation of the tension means drive results. The invention furthermore relates to a corresponding computer system.
