摘要： Method and apparatus for suppressing differential and common mode conducted electromagnetic interference emission in electrical equipment powered from a grounded A.C. line source without creation of a shock hazard. Differential mode interference is suppressed by connecting a capacitor across the power lines and common mode interference is suppressed by an inductor inserted in the ground lead, both positioned within the equipment case or housing. The capacitor and inductor can have substantially fixed values for a wide range of equipment. In the preferred embodiment, the inductor is constructed by winding a few turns of the ground lead itself through a high permeability, ferrite toroid positioned within the case or housing.

摘要： A method and apparatus for selectively demetallizing a metallized film whereby the metallized web is selectively demetallized by bringing the web into contact with two electrodes, one of which contacts a greater surface area of the web than the other, and maintaining an electrical potential difference between the two electrodes. Preferably, the electrodes comprise rollers, one of which may be provided with a predetermined pattern. The potential difference between the respective electrodes can be controlled to effect selected demetalization of predetermined desired regions of the web or to vary the extent of demetalization from a desired region. The web material can subsequently be used as microwavable packaging material.
