Abstract: A magnetic clutch for actuating a disconnect clutch includes an axis of rotation, an axially fixed stator, an axially movable armature, a torque-axial force converter unit with an armature side and a bearing side, and a rotary brake. The axially movable armature is axially retainable on the stator by a magnetic force from a power supply. The torque-axial force converter unit acts in an antagonistic manner to the magnetic force to hold the armature at an axial distance from the stator. The rotary brake is for effecting a rotational speed difference between the armature side and the bearing side. Other aspects of the disclosure include a disconnect clutch for an internal combustion engine in a hybrid drive train, a hybrid drive train, and a method for controlled closing of the disconnect clutch.

Abstract: The invention relates to a process for manufacturing a laminated material (S) comprising a fibrillated cellulose layer, characterized in that it comprises the following steps: (a) depositing a suspension (1) of fibrillated cellulose on a filtration membrane (2) and draining the suspension through that membrane so as to form a wet layer of fibrillated cellulose (A) having a dryness, that is to say a ratio between the mass of dry matter and the total mass of the fibrillated cellulose layer, of between 5% and 18%; (b) transferring the wet layer (A) under pressure to an at least partially hydrophilic surface of a substrate (B), so as to form the laminated material (S); (c) drying the laminated material. The invention also relates to a device for implementing the process.
