Abstract: An apparatus for treating liquid includes a tank having a water inlet for receiving water, a treated water outlet for outputting treated water and a flow path between the inlet and the outlet. An injection section of the tank is located along the flow path of the tank with an outlet toward a bottom of the tank. Ozonated liquid containing ozone microbubbles is injected through an injection manifold positioned within the injection section of the tank. The ozone microbubbles adsorb to impurities in the ozonated water. A separation section of the tank is positioned downstream of the outlet of the injection section. The separation section has a contact surface such that the ozonated water travels upward to contact the contact surface and such that at least a portion of the ozone microbubbles adsorb to the contact surface.

Abstract: A transmission device with at least two output shafts and at least two multi-shaft planetary gearsets that are actively connected with one another. A shaft of a planetary gearset can be actively connected with an output shaft. In addition, a shifting mechanism, located between the two output shafts, shifts between a first power path or a second power path. In one of the planetary gearsets, torque from an electric machine can be transmitted along either the first or the second power path. In the first power path, torque from the electric machine is transmitted to the two output shafts in equal parts and with the same sign. In the second power path, torque is transmitted to the two output shafts in equal parts but with opposite signs. The planetary gearset, in the area of which the torque from the electric machine can be transmitted, is a simple negative planetary gearset.

Abstract: A method for operating a drive train of a motor vehicle. The drive train comprising a hybrid drive with an internal combustion engine and an electric motor, a transmission arranged between the hybrid drive and a drive output, and a clutch arranged between the internal combustion engine and the electric motor. The internal combustion engine is started by engaging the clutch only when the electric motor is providing drive power. In this situation when shifting gears in the transmission with interruption of the traction force, immediately after the gear change and during a load build-up phase of the shift operation, the internal combustion engine is started by the electric motor without traction force interruption. The clutch is controlled to partially engage to start the combustion engine and then it is completely disengaged before reaching a synchronous speed between the combustion engine and the electric motor.

Abstract: A dual clutch transmission for a front-transverse arrangement including a dual clutch and two partial transmissions (PG1, PG2). Each of the two clutches (K1, K2) of the dual clutch acts on one coaxial transmission input shaft (AW1, AW2), which acts upon a partial transmission (PG1, PG2). The partial transmissions are designed as planetary transmissions (PG1, PG2) that are to be shifted in a positive manner. The output is located on the same side of the transmission as the input and is axially parallel to the input in the same rotational direction. Torque is transmitted through the dual clutch transmission to the output shaft (Ab) by way of at least one intermediate shaft (W1, W2) that is parallel to the transmission input shafts (AW1, AW2).

Abstract: The invention relates to a medical plaster which is able to supply damaged skin and open wounds with an active compound which helps to accelerate wound healing and allows it to proceed better. The plaster has novel design features which enable, in particular, protein- or peptide-containing medicaments, such as, for example, erythropoietin (EPO), to exert their wound-healing or wound-healing-promoting action by release of the active compound from the plaster without being significantly deactivated or metabolized in the process by substances occurring in the wound secretion.

The ploughshares have a length between a leading edge and a trailing edge of at least 1.5 feet and are spaced apart at the trailing edge by at least two feet, to provide an average lift angle of upward lift of between 10 degrees and 15 degrees.
