Abstract:
1. A high-voltage interference frequency generator ( 11 ) comprising a hollow cylindrical housing ( 12 ) containing piezoelectric pillars ( 13 ) for the conversion of mechanical pressure into electrical voltage which is short-circuited by spark gaps ( 37 ), characterized in that a mechanical pulse generator ( 25 ) is connected in series with said housing ( 12 ), two said piezoelectric pillars ( 13 ) each comprising a plurality of axially polarized piezoelectric discs being electrically connected in series in opposite relationship by an electrically conductive coupling portion ( 15 ), electrodes ( 34 ) extending from opposite ends ( 18 ) of the pillars ( 13 ) along the lengths of said pillars into the region of the coupling portion ( 15 ) said electrodes ( 34 ) terminating at proximate ends thereof into spark electrodes ( 36 ) for forming said spark gaps ( 37 ) extending towards the coupling portion ( 15 ) and between each other, said mechanical pulse generator ( 25 ) imparting an axial force against said piezoelectric pillars ( 13 ) to generate a voltage resulting in a build-up of mutually superimposed, oscillating electromagnetic fields and intensive microwave emission of wide-bond nature through the short-circuiting across the spark gaps ( 37 ).
