Abstract: A portable handheld edge cutter (1) has a cutterhead (2) fixed to a guide tube (4). Two wheels (6, 7) are attached to the cutterhead (2). The cutterhead (2) includes a gear unit mounted in a gear housing (8). A first wheel (7) is rotatably journalled on a first end (27) of the gear housing (8). On the opposite-lying end (28) of the gear housing (8), a cutting knife (9) is mounted and is rotatably driven by the output shaft (18) of the gear unit. In order to achieve a simple assembly of the edge cutter (1) and to protect the gear housing (8) against wear, the second wheel (6) is mounted between the gear housing (8) and the cutting knife (9) and that the two wheels (6, 7) are journalled coaxially to the output shaft (18).

Abstract: A node may contain a secure store agent. A process executing on the node may request connection information from the secure store agent. An encryption key phrase may be accessed, responsive to the request for connection information, to decrypt the requested connection information. The requested connection information may be obtained from a secure storage file in a file system.

Abstract: The invention relates to an operating medium tank (1) for a drive unit (2), especially for an internal combustion engine (3) of a portable handheld work apparatus. The tank (1) has a fill opening (4) and a output opening (5) in the housing wall (6) of the tank. According to the invention, at least one base (7) having a lug (8) is formed as one piece from the housing wall (6) in order to configure the tank so as to be operationally safe and easy to assemble. The tank (1) can be fixed with the aid of the lug (8) so as to be form-tight and separable on a receptacle (9) of the drive unit (2).

Abstract: The invention relates to an apparatus and to a process for batchwise preparation of polycondensation polymers having an intrinsic viscosity of from 50 to 150 cm3/g at the particular polycondensation temperature.

Abstract: A first base station, which is coupled to a first switching system part is set up within radio range of a second base station, which is coupled to a second switching system part. After initial synchronization of the first base station to the first switching system part and of the second base station to the second switching system part, the second base station receives radio frames transmitted from the first base station and determines their time error with respect to its own radio frame clock. The determined time error is then transmitted to the second switching system part. In response to this, the second switching system part transmits a synchronization signal to the second base station, with the transmission time being chosen as a function of the transmitted time error such that the radio frame clock of the second base station is synchronized with the radio frames of the first base station by time alignment with the synchronization signal.

Abstract: A resistance welding apparatus characterized by very low output impedance, and providing a substantially constant voltage source to low impedance (e.g., resistances on the order of 1-100 micro-ohms) materials-to-be-joined. The welding apparatus includes one or more primary and secondary winding pairs disposed about a high permeability core with the secondary coil(s) positioned between the primary coil(s) and the core. In a preferred form, the secondary coil(s) are capable of delivering more than 75,000 amperes of welding current. The welding apparatus is lighter, more cost efficient, and more energy efficient than conventional systems.
