  • Publication number: 20030230934
    Abstract: The modular power supply of the present invention provides a new device and method for powering multiple portable and/or small devices each requiring an AC or DC current source at one of various low-voltage levels. The invention comprises a main power base that is capable of converting AC power levels in common use internationally into a main low-level DC bus, which may, for example, be 24VDC. The AC input source and the derived DC voltage are then supplied via separate buses to smaller power “blocks” of two distinct designs, one for transforming the AC bus voltage to a low-voltage AC output, and one for converting the DC bus voltage to a low-voltage DC output. The DC blocks are of a common design, but are differentiated in that their respective output voltages are set by a “programming” element. The AC blocks are of a second common design, but are differentiated in that their respective output voltages are set by a “programming” transformer.

  • Patent number: 5262111
    Abstract: A process for the continuous production of a rubber compound in a twin-screw extruder is disclosed that improves the dispersion of carbon black in the extrudate while reducing the specific energy requirements of the extrudate. Rubber is fed into the extruder together with a processing aid and masticated up to a temperature of 120.degree. C. to 180.degree. C. Subsequently, a first part of carbon black representing preferably 40% to 80% of the whole quantity of carbon black is fed into the heated extrudate. Afterwards, plasticizing oil is added to the extrudate before the second remaining carbon black part is fed and incorporated into the extrudate at a temperature of 120.degree. C. to 180.degree. C. The whole compound is then cooled, a crosslinking agent is added, and the compound is homogenized and extruded.
