Abstract: Methods and apparatuses for validating a message with a signature. The method may include receiving the message with the signature and carrying out an integrated validation and storing process. The signature may be validated based on a validation algorithm and a key. The received message may be stored in a database. A method for generating a signature for a message may include carrying out an integrated receiving and generating process. The message to be sent may be received and the signature may be generated based on a signing algorithm and a key. The message may be sent with the signature.

Abstract: The present invention relates to a device and a method for continuously producing a plastic plate and/or film comprising lugs or anchors that are formed therewith in one piece, wherein the molten plastic is guided in the form of a flat web through a gap between a roll and a circulating device, wherein said circulating device comprises circulating shaping strips having recesses for forming the anchors, and the shaping strips, when passing from a straight section into a curved section of the circulating device, open thereby enabling the formed anchors to be released or ejected without force. The device of the present invention and the method of the present invention enable a continuous production of anchor plates comprising, in particular, non-positive and complicated anchor shapes that can be realized quickly and with a few working steps.

Abstract: The invention relates to a filter for an open system interconnection layer2 traffic separation in at least one Access Switching Router (42) in a network (40), having ports in the routers (42, 44) configured to the same virtual local area network. The filter is filtering data packet traffic to the ports, simulating that if the source device and destination device is in the same layer2 domain, the router layer2 address is the actual destination address both for the source and destination device. It is also simulating that if the source device and destination device are not in the same layer2 domain but in the same layer3 subnet, the router layer2 address is the actual destination layer2 address for the source to the destination. By this filtering is providing the use of one IP subnet, spreading it over several premises and a multiple of Access Switching Router and the same subnet in multiple layer2 domains, thus covering more customers.

Abstract: The present invention relates to a tool coupling device comprising a coupling element (10) attachable to a machine tool and a tool adapter (11) intended to clamp a tool for chip forming machining. A plug (18) on the adapter (11) is related to a contact surface (30;38) that is intended to be in engagement with a corresponding contact surface (29;37) related to the coupling element (10), said engagement clamping the adapter (11) against the coupling element (10).
