An adsorbent for separating nitrogen from a mixed gas of oxygen and nitrogen is MSC wherein an oxygen and nitrogen separation ratio α and a ratio (t95 / t50) of a time t50 required for adsorbing 50% of the oxygen equilibrium adsorption amount and a time t95 required for adsorbing 95% of the oxygen equilibrium adsorption amount satisfy the inequality(t95 / t50)<0.4×(α−24)α≧35.The amount of adsorbent used with respect to a predetermined amount of nitrogen generated can be reduced since a method is carried out which uses this adsorbent to produce nitrogen by separating nitrogen from the mixed gas of oxygen and nitrogen by means of a PSA method. By this method, it is possible to reduce the cost of the apparatus and reduce and miniaturize the scale of the apparatus, and the power consumption amount can be reduced.

An actuating device for a friction clutch device installed in the drive train of a motor vehicle introduces actuating forces, especially clutch-engaging or clutch-releasing forces, to the friction clutch device to actuate at least one friction clutch of the friction clutch device in the engaging or releasing direction. At least one actuating element assigned to a friction clutch can be shifted axially relative to at least one support element, which is essentially fixed in the axial direction, to exert the actuating forces. The actuating element belongs to an actuator assigned to the clutch or can be shifted axially relative to the support element by the intermediate action of an actuator assigned to the clutch. The actuating element and the support element engage with each other in such a way that a rotational movement of the actuating element relative to the nonrotatably supported support element, this movement being imparted by the intermediate action of the actuator, is converted to an axial translational movement of the actuating element relative to the axially supported support element.
