Abstract: A cutting tool (100) includes a top blade (102) and a bottom blade (104). The bottom blade (104) is pivotally coupled to the top blade (102). The top blade (102) and the bottom blade (104) together perform a cutting action on an object place between them. A first handle (108) is operatively coupled with the top blade (102). The first handle (108) defines a front portion (109) and a back portion (111). A second handle (110) is operatively coupled with the bottom blade (104). The cutting tool (100) is characterized in that in closed position of the cutting tool (100), at least a part of the second handle (110) at least partially encloses the back portion (111) of the first handle (108).

Abstract: A method and a device for operating a closed-loop or open-loop speed-controlled electric motor of a fan drive, which motor is connected to an on-board system voltage of a motor vehicle and the motor speed of which is set to a defined first desired speed, wherein, if the on-board system voltage fluctuates, the motor speed is set to a desired speed that is lower compared with the first desired speed.

Abstract: Catalyst system comprising a. a procatalyst composition comprising a transition metal compound, a metal compound and an internal donor, and b. an external donor being an diethoxy-substituted silane, wherein c. said internal donor being chemically different to said external donor.

Abstract: A hydraulic unit (5) for a cylinder head (2) of an internal combustion engine with a hydraulic, variable valve train (1) is provided. In the hydraulic unit, a high-pressure chamber (11), a medium-pressure chamber (12), and also a low-pressure chamber (16) used as a hydraulic medium reservoir are formed. The low-pressure chamber communicates merely via a choke opening (17) with the medium-pressure chamber, wherein the choke opening passes through a separating wall (18) extending between the low-pressure chamber and the medium-pressure chamber.

Abstract: A device for hydraulic control of gas exchange valves of a reciprocating internal combustion engine which has slave cylinders in operative connection with one or more gas exchange valves and master actuators in operative connection with at least one cam provided with a basic and cam profile of a camshaft that is rotatably driven by the engine and can be hydraulically connected to the slave cylinders. The device also has a control device controlled by an actuating member, the device controlling the volume of hydraulic liquid fed to the slave cylinders, and at least one feed line, via which low pressure liquid from a pressure source can be fed to the device by means of at least one non-return valve. The actuators have displaceable vanes, a component carrying the vanes, and cells limited by walls. The vanes are in operative connection with the basic and cam profile of the cam.

Abstract: Valve controller for reciprocating piston internal combustion engines with at least two intake and/or exhaust gas-exchange valves for each piston/cylinder unit, wherein the gas-exchange valves are guided by valve stems in a cylinder head (8) of the reciprocating piston internal combustion engine, loaded in a closing direction by valve springs, and can be controlled via a common bridge (10) by an activation device, wherein the bridge (10) is guided over a sliding surface parallel to the movement of the gas-exchange valves, the bridge (10) has at least one hydraulic valve clearance compensation element (14 or 15) that connects to a gas-exchange valve, and a device is provided that prevents rotation of the bridge (10) about the sliding surface.
