Claim 3
Dependent Claim
73 words
A CAPACITOR COMPRISING: A RECTANGULOID RIGID DIELECTRIC BODY MEMBER HAVING TWO PARALLEL SURFACES OF RELATIVELY MAJOR AREAS; AND A PAIR OF U-SHAPED CONDUCTIVE PLATES BONDED TO SAID BODY MEMBER IN OPPOSED RELATIONSHIP, EACH OF SAID PLATES HAVING A PAIR OF PARALLEL ARM PORTIONS DISPOSED ON SAID SURFACES AND HAVING ENDS TERMINATING IN A PLANE, SUCH PLANES BEING IN PARALLEL AND SPATIALLY OPPOSED, WHEREBY THE CAPACITIVE EFFECT IS EXHIBITED PRIMARILY BETWEEN SUCH OPPOSED ENDS.
