ABSTRACT:
Improvements in a capacitive structure comprising a plurality of capacitive layers in stacked relation to one another with indentations along their edges. Similar upper and lower dielectric covers with beveled portions along their edges cover the uppermost and lowermost capacitive layers. Along each edge, a mass of conductive material provides electrical connections and covers the beveled portions of the respective covers as well as the edges of the respective covers and of the capacitive layers, so as to lock the respective covers onto the capacitive layers. The respective covers are provided with parallel grooves, which may be washed or flushed, as by means of pressurized air, so as to remove contaminants.
