Abstract: In a method for electronically documenting license information via the granting of a license and the use of said license in a network of several electronic data processing devices, the license information is added with a new transaction block to a decentralized transaction database and is managed using blockchain technology. When a license is granted to a licensee, a licensor generates new license information with a licensing input, the licensing input contains at least one license identification, and before, during or after use of the license granted by the licensor the licensee generates new license information with a license use input, and the license use input contains at least the license identification of the licensing input and a use identification. The licensing input can contain a license key encrypted with a public key of the licensee, with which the licensor and the licensee can generate and decrypt encrypted information.

Abstract: The present invention relates to a handle, in particular for use in a screwdriver. Such handle comprises an outer region having a first stiffness and an inner region comprising a second stiffness. According to the invention the second stiffness is smaller than the first stiffness. The inner region might be built with chambers and ribs wherein the chambers might be hollow or filled with a soft material, e.g. a gel or a soft porous or non-porous plastic material.

Abstract: A method for determining the relative level of contamination of a component in a water treatment infrastructure is disclosed. The method includes the steps of at least partially filling the component with water; isolating the component from the remainder of the infrastructure; taking a control water sample from the component at a point in time Ts and determining the quality of the water sample at Ts; storing the control water sample for a preselected test period Tt and in a container which will not affect the quality of the water sample; taking a second water sample from the component at a point in time Ts+Tt; determining the quality of the second water sample and the quality of the control water sample at Ts+Tt and calculating the water quality decrease in the control sample and the second sample during the test period Tt. The relative level of contamination of the component is calculated by subtracting any water quality decrease in the control sample from the water quality decrease in the second sample.

Abstract: A ground breaking apparatus has a vehicle with a cutter assembly attached thereto. The cutter assembly has a rotating cutter mounted to a cutter housing which is attached to and movable with the vehicle. The cutter housing has a forward door that moves between open and closed positions. A pusher bar is movable between an operating and a raised position is also included. When the door is open and the pusher bar is in the operating position, the vehicle moving forward will cause the pusher bar to engage trees which will also be engaged and cut, or ripped by the rotating cutter. The door may be closed in the direction the vehicle reversed. The cutter may be lowered so that as the vehicle moves in reverse, the rotating cutter head mulches trees into the soil and also breaks up ground fragments to prepare the soil for the desired use.

Abstract: A screw driver (50) for use with electrical appliances under voltage includes a handle (1) and a functional part (2) with a shank (3) and an end piece (5). The shank (3) is designed to be partly covered by an insulating sleeve (9) made of plastic. The end piece (5) is insulated and connectable to said handle (1) so that torque is transferable from said handle (1) to said functional part (2). The handle (1) is insulated from said shank (3). Furthermore the screw driver (50) includes a holding device (11) which is connected to the handle (1) and comprises a secured position and a released position. The holding device (11) is manually operable between the secured position and the released position. In the secured position the holding device (11) positively engages the functional part (2) such that the functional part (2) cannot be detached from the handle (1). In the released position the functional part (2) is allowed to be detached from said handle (1).

Abstract: A magnetic screw-holding device is assembled close to the profile tip on the shank of a hand-screwdriver or screwdriver-insert with long shank. The device essentially consists of a sleeve made of non magnetic-conducing material in which a magnet is fixed at the front side or of a magnet made of magnetic material embedded in a plastic binder produced by injection molding. The sleeve with the magnet or the magnet can easily move in longitudinal direction and is or can be brought into such a position relative to the profile tip that by the force of the magnet-field the sleeve or the magnet moves automatically into a position in which the front face of the magnet contacts the surface of the screw head and also attracts the screw onto the profile tip so that it completely penetrates into the recess in the screw head if a screw is placed on the profile tip.
