The invention relates to a friction lining (1) for a wet-running friction clutch element that rotates without a preferred direction of rotation in the assembled state, having at least one annular disc-shaped The contact friction surface (4) has grooves (5, 6) through which coolant can flow. The grooves (5, 6) form two groove groups superimposed on each other. The friction surface (4) has no groove edges oriented perpendicular to the direction of rotation. Each groove (5) of the first groove group acts as a through groove from the friction surface - inner diameter (d_i) to the friction surface - outer diameter (d_a) extension. Each groove (6) of the second groove group acts as a through groove from the friction surface - inner diameter (d_i) to the friction surface - outer diameter (d_a) extension. Each groove (6) of the second groove group intersects with a groove (5) of the first groove group in such a way that a groove intersection (8) lies on the friction surface-inner diameter (d_i), or a groove intersection (7) Located on the friction surface - outer diameter (d_a). Here, the total groove cross-sectional area on friction face-inner diameter (d_i) or friction face-outer diameter (d_a) is less than one between friction face-inner diameter (d_i) and friction face-outer diameter (d_a) Friction Surface - The total groove cross-sectional area in diameter.

The disclosure relates to a fuel cell system and a method for controlling the fuel cell system (100) comprising a fuel cell stack (10) for providing an electrical power Pstack depending on a power demand, at least one auxiliary unit (24, 26, 33, 34, 38) for operating the fuel cell stack (10) with an electrical power consumption Paux, at least one consumer (44, 51) with an electrical power request Puse, and a control unit (60) for regulating the power demand as well as a method for controlling such a fuel cell system. It is provided that the control unit (60) is configured to selectively operate the fuel cell system (100) in a first operating mode or in a second operating mode, whereby the fuel cell stack (10) is turned off depending on the operating mode upon the falling below of an optimal efficiency degree operating point P(Eta max) of the fuel cell system (100) or a minimum operating point Pmin of the fuel cell stack. In particular, at least one auxiliary unit (24, 26, 33, 34, 38) is also turned off in the first operating mode, when the optimal efficiency degree operating point decreases.

A device for handling stacking or removing articles from a stack, has a stacking wheel located between the lifting elements for stacks and a conveyor. When the stacking wheel turns, depending on the direction of its rotation, an article is moved from the conveyor onto the stack in the lifting direction. The stacking wheel bears pairs of holding plates distributed around its periphery; on them swivelling fingers are supported. The swivelling fingers are pressed by springs into their action position in which they project over the facing surfaces of the holding plates and fit into receiving openings of the articles when articles are moved by the stacking wheel. Control plates are assigned to the stacking wheel and engage with their ramp edges the concave, downwardly pointing surface of the swivelling fingers to swivel them into their readiness position which does not project to the inside over the holding plates.

A method of forming a composite component in which the component comprises a series of sub -layers and in which the sub -layers are offset with respect to one or all of the other sub -layers forming the composite component.

Spray head, which comprises a spray head body (2), which comprises at least one nozzle (3), a heat-activated triggering element (5), in connection with the spray head of which a protection means (6) is arranged, which protection means is in front of the nozzle (3) in the protective position and mechanically protects the triggering element (5) when the spray head is in a non-active state, and which protection means (6) can be moved to a second position, in which at least one nozzle (3) and the triggering element (5) are not protected by the protection means (6). The triggering element (5) is fitted onto the fixing body (4) of the triggering element, which fixing body can be moved with respect to the spray head body (2) between two positions, a first position in which the spray head is in the non-active state and the fixing body (4) of the triggering element is in the retracted position, and a second position in which the fixing body (4) of the triggering element is pushed out, and which fixing body (4) of the triggering element is arranged to move with respect to the spray head body (2) from the effect of the pressure of the medium from a first position to a second position and at the same time to exert a force on the protection means (6), for moving the protection means from the protective position to a second position, in which case the spray head is placed into a state of readiness in the second position of the fixing body of the triggering element.

The invention is concerned with control of a continuously variable vehicle transmission. The transmission in question is to have a variator (10) which is coupled between a rotary transmission input (32) and a rotary transmission output (46), to provide continuous variation in a transmission dive ratio, via a launch device such as a clutch (62; 68). The variator and the launch device are constructed and arranged to exert a required torque, defined by an input signal. In accordance with the invention, the same control signal is used to control both the variator torque and the torque capacity of the launch device. In such an arrangement, vehicle launch (i.e. moving away from rest) can be controlled in a straightforward manner by progressively raising the relevant control signal, preferably a hydraulic pressure signal. Further independent claims are including for applying traction load to races (20, 22) of the variator and for a method setting torque of the launch device (62; 68) higher than torque of the variator (10).
