    摘要： A device and method for forming a tubular braid comprising a plurality of filaments. The braiding machine comprises a disc with a mandrel extending from the center in a perpendicular direction and a plurality of catch mechanisms arranged circumferentially around the edge of the disc. A plurality of filaments are temporarily affixed to the mandrel, each filament extending from the mandrel toward the edge of the disc and engaging the edge of the disc at a discrete point of engagement. The plurality of catch mechanisms are attached to actuators adapted to move the catch mechanisms in a generally radial direction relative to the edge of the disc to allow the catch mechanism to engage a subset of the filaments and move the engaged filaments beyond the circumferential edge of the disc.

    摘要： The present invention relates to a DC voltage converter with soft switching of the type with half-bridge arrangement at the primary side and of quasi-resonant half-wave type at the secondary side. This converter comprises a single transformer and can generate a plurality of regulated voltages at output. It furthermore comprises a resonant circuit for creating a half-wave resonant current in the secondary winding and charging a first load capacitor so as to produce a first DC voltage. It furthermore comprises an inductive circuit connected between said secondary winding and a second load capacitor able to generate a current so as to charge the second load capacitor during a part of the half-wave of the resonant current flowing in the secondary winding and thus produce a second DC voltage.

    摘要： The present invention relates to a DC/DC converter of half-bridge type with soft switching comprising a transformer. The primary of the converter is of the type with half-bridge arrangement and is linked to an input voltage source by way of two switches and the secondary is of half-wave type and is linked to a load by means of an inductance. Means are provided for alternately controlling the two switches, at fixed frequency, by pulse width modulation. To reduce the number of components of the converter, a capacitor of small value is arranged in series with said primary winding, which capacitor referred back to the secondary is designed to resonate with said inductance. The inductance is the transformer's leakage inductance seen from the secondary. The switches are advantageously switched while the current in said inductance is not zero.
