Abstract: A method for obtaining recyclate from thermosetting materials, comprising the following method steps: providing thermosetting starting materials to be recycled; breaking the thermosetting starting materials with a twin-shaft shredder to obtain a plurality of fragments; shredding the fragments with a single-shaft shredder to obtain a plurality of flakes; and fine grinding of the flakes with a grinding device to obtain a recyclate powder.

Abstract: The invention relates to a fuel cell system assembly comprising at least two coupled fuel cell systems (A, B) that can be operated at different load points, each fuel cell system (A, B) being connected to a respective cooling circuit (3A, 3B) comprising a circulating coolant, via a coolant supply line (1A, 1B) and a coolant drain line (2A, 2B). According to the invention, the cooling circuits (3A, 3B) are coupled via a common return line (4), via which the coolant supply lines (1A, 1B) can be supplied with coolant, and a return conduit of at least one ancillary unit (5, 6), for example an electric heating device (5) and/or a heater core (6), is connected to the common return line (4).

Abstract: The invention relates to a hydraulic hybrid drive system (1) for a motor vehicle, comprising driven wheels (2), which have friction brakes (3) for applying a friction braking torque to the driven wheels (2), and a continuously adjustable hydraulic transmission (4), which has a motor-side hydraulic machine (5) and a wheel-side hydraulic machine (6) having a direct fluid connection to the motor-side hydraulic machine, wherein the hydraulic machines (5, 6) are connected in series and to the driven wheels (2) of the motor vehicle in regard to driving, such that the hydraulic machines (5, 6) can be operated both as hydraulic pumps and as hydraulic motors, and at least one hydraulic fluid energy storage device (7), which is connected to the hydraulic transmission (4) in regard to fluid flow, wherein the motor-side hydraulic machine (5) is connected to the wheel-side hydraulic machine (6) in regard to fluid flow by means of a high-pressure hydraulic line (8) and a low-pressure hydraulic line (9).
