    摘要: The present invention relates to an arc-quenching device for circuit breakers having double-break contacts for use in low-voltage distribution systems. Provided around a prechamber (41) is a magnetic shield (91) for the purpose of intensifying the magnetic blowing action on an arc formed between the arc guide rails (51, 61) of the prechamber. In addition, a blowing loop (81) is inserted in the arc-quenching circuit and extends in sections parallel to an arc guide rail (61). Prechamber insulation having a bulge constricting the arc area likewise serves the purpose of optimizing the arc run.

    摘要: A paver hopper flap suspension system has a number flaps attached to the hopper frame. A cable restraint line is attached to the flaps. A tensioning system is attached to the cable restraint line. The tensioning system allows the flaps to distort as the loading truck body engages the hopper entrance. Once the truck exits the hopper entrance the hopper flap suspension system causes the flaps to spring back to their original shape. The suspension system may include a torsion spring biasing the flaps into a vertical position. The tensioning system may include a tension adjuster. Using this system the flaps are not torn and hold the asphalt in place as the loading trucks dump asphalt into the hopper.

    摘要: Circuit arrangement for operating discharge lamps (LP), having the following features: A power factor correction device (PFC) provides an intermediate circuit voltage; an inverter (INV), which draws its power from the intermediate circuit voltage, outputs power to discharge lamps (LP). According to the invention, an oscillation of the power factor correction device (PFC) only takes place when it is started, by means of a starting device (TRG), by an oscillation of the inverter (INV). This provides cost-effective control of the sequences in the circuit arrangement.

    摘要: An arrangement for producing a connection between two structural parts for preventing any relative movement thereof, consists of a blind bore in the one part and a through bore in the other part, a pin being inserted in fitting manner into the blind bore and projecting into the through-hole. Since the diameter of the through-hole is larger than the diameter of the blind bore an annular space is obtained within the through-hole which is filled out by a sleeve which is deformable through application of ultrasonic waves.
