The invention relates to a dynamic mixer (1, 100) for a plurality of fluid components, comprising a housing (2, 102) and a rotor element (3, 103) which is rotatably arranged in the housing, wherein the housing comprises a respective inlet opening (12, 13, 112, 113) at least for each component, and at least one outlet opening (20, 120). An annular space is provided between the rotor element and the housing, in which annular space a mixing element (7, 107) connected to the rotor element is arranged. The mixing element is provided with a blade element (23, 43, 53) configured as a guide element for conveying the components from the inlet opening to the outlet opening. The blade element (23, 43, 53) is a guide element and comprises a guide surface (25, 45, 55) of concave curved shape with respect to the outlet opening (20, 120). The blade element is further removed from the outlet opening (20, 120) on the upstream side thereof than on the downstream side thereof.

The invention relates to a hand-guided electric tool having a motor and a pulse width modulator for generating a pulse width modulated signal for operating the motor. A unit is provided for reducing the EMC interferences emitted by the electric tool.

An improved system for removing particulates from the cooling air in a gas turbine engine (10) has a separating element (60) set axially opposite to the air inlet (20) from the compressor (12) and comprising a circular sleeve fitted to the turbine housing. The cooling airstreams are ducted into the cooling air inlets (54, 55) via a non direct path. Particulates are prevented from blocking the air inlets and are taken into the burn chambers.

The invention relates to a method for producing a piston ring (1) provided with a butt joint (5), in that an annular metal main body is provided with at least one hard layer (2') at least in the area of the outer circumferential surface (2) of said main body, wherein after this coating the inner circumferential surface (3) of the piston ring is at least partially subjected to a wall-thickness-reducing material removal process.

The invention relates to photovoltaic thin-film solar modules, comprising in a first embodiment, particularly in the following order: at least one substrate layer; at least one rear electrode layer, particularly directly contacting the substrate layer; at least one conductive barrier layer, particularly directly contacting the rear electrode layer and / or the substrate layer; at least one contact layer, particularly an ohmic contact layer, particularly directly contacting the barrier layer; at least one semiconductor absorber layer, particularly a chalcopyrite or kesterite semiconductor absorber layer, particularly directly contacting the contact layer; optionally at least one first buffer layer, particularly directly contacting the semiconductor absorber layer and containing or substantially made of CdS or a CdS-free layer, particularly containing or made substantially of Zn(S, OH) or In2S3; and / or optionally at least one second buffer layer, particularly directly contacting the semiconductor absorber layer or the first buffer layer and containing or substantially made of intrinsic zinc oxide and / or high-resistance zinc oxide; and at least one transparent front electrode layer, particularly directly contacting the semiconductor absorber layer, the first buffer layer and / or the second buffer layer and particularly containing or substantially made of n-doped zinc oxide. Said thin-film solar modules further comprise: spaced-apart first structuring separation trenches filled with at least one insulating material, said trenches separating adjacent solar cells from one another down to the substrate layer; spaced-apart second structuring separation trenches filled or provided with at least one conductive material, said trenches extending to the contact layer or to the rear electrode layer or to the barrier layer, particularly to the barrier layer and each being adjacent to a filled first structuring separation trench; spaced-apart third structuring separation trenches, which extend to the contact layer or to the rear electrode layer or to the barrier layer, particularly to the barrier layer, and are each adjacent to a second structuring trench on the other side of the first structuring trench to which the second structuring trench is adjacent; and at least one conductive bridge from second structuring trenches filled with a conductive material or furnished with such a material to the front electrode layer of the adjacent solar cell, across adjacent first structuring separation trenches filled with insulating material. The invention further relates to a method for producing such thin-film solar modules.

The invention relates to a method and a device for controlling a drivetrain of a vehicle, particularly a hybrid vehicle. The drivetrain comprises at least two drive units. One drive unit is an internal combustion engine (202), the other is another motor (204). A temperature value representing the exhaust gas temperature of the internal combustion engine is detected. The proportion for generating the drive torque by means of the another motor is set as a function of the exhaust gas temperature such that a greater proportion of the driving torque is generated by means of the another motor at higher exhaust gas temperatures than at lower exhaust gas temperatures.
