    Abstract: A supply arrangement selectively operates from either one of dual AC mains supply voltages of, illustratively, 220 or 110 volt RMS AC. When the arrangement operates from the 220 volt AC mains supply voltage, a bridge rectifier, operating as a full-wave rectifier, charges each of series coupled first and second capacitors to one-half the peak of the AC mains supply voltage. During the positive half-period of the AC mains supply voltage, a positive voltage, equal to the difference between the instantaneous mains supply voltage and the DC voltage across the first capacitor is coupled between two terminals of a load such as a degaussing circuit. A corresponding negative difference voltage, is coupled between the two terminals during the other half-period. When the supply arrangement operates from the 110 volt AC mains supply voltage, the rectifier arrangement is reconfigured to permit the entire mains supply voltage to be coupled between two terminals of the load while enabling the bridge rectifier to operate as a voltage doubler.

    Abstract: A double-ended ceramic metal halide lamp includes a luminous tube; at least two illuminators serially connected with each other deposed inside the luminous tube; and at least one ring-shaped retainers arranged between two illuminators to support the illuminators located along a central line of the luminous tube. A manufacturing method for a ceramic metal halide lamp includes following steps: (1) Arrange at least two serially connected illuminators inside an interior of a luminous tube; (2) Seal two ends of the luminous tube by a press sealing technique; and (3) Extract out the gas inside the luminous tube to form an eyelet at a central portion of the luminous tube.

    Abstract: This present invention describes a system of waterproof shoes with thermoplastic polyurethane (TPU) insteps, including vamp, instep and sole, in which the waterproof welt coated with waterproof glue is gummed on the seam between the vamp and the sole; the metal section, instep, mid-sole and inner welt is formed in integration by injecting with TPU polyurethane, in which the outer and inner welts are gummed with glue and sewn firmly with threads on the opposite sides of the instep; a metal piece is put between the thin bottom and the filling materials on the bottom side of the instep. The waterproof methods (the waterproof outer surface of the instep, and the waterproof welt coated with waterproof glue and gummed on the seam between the vamp and the sole reach the purpose of saving the materials and labor, obtaining the waterproof effects which is even better than those of the traditional waterproof shoes and may provide more functionality and better visual effects.
