  • Patent number: 6620011
    Abstract: A strip-shaped screw magazine having a plurality of spaced from each other connection webs (2, 12, 22) extending between two side walls (1, 11, 21) of the magazine transverse to the longitudinal extent of the screw magazine and defining a plurality of substantially square chambers (9, 19, 29) for receiving each a screw (8, 18, 28), and a sleeve (6, 16, 26) for receiving a stem of the screw (8, 18, 28) and arranged centrally in each of the receiving chambers (9, 19, 29), the receiving sleeve (6, 16, 26) having at least two break points (5, 25) and being connected by at least two support arms (3, 13, 23) uniformly arranged on the circumference of the sleeve with the side walls and/or the connection webs.

  • Patent number: 6597156
    Abstract: The invention is directed to an arrangement and a method for generating high voltage from a low-voltage supply source using a charge reservoir chargeable and rechargeable to the desired high voltage or higher via a charge pump. A first switching device regulates the supply of electric charge from the precharged charge reservoir to a separate storage capacitor. As a result, a high voltage signal that is extensively noise-free is available during certain operating phases, such as a measurement process. A second switching device ensures a regulated discharge from the storage capacitor when the capacitor is overcharged, for example, for the readjustment of the high voltage to be generated. A capacitive voltage divider, which reduces the high voltage without losses, is provided to determine the actual value of the high voltage. At very small currents, the desired high voltage can be maintained by using the capacitive voltage divider for a substantially longer time than by using an ohmic voltage divider.
