Abstract : The invention is directed to providing a method and means for improving the coupling between a ferroelectric stack and a head and tail mass including a coupler means bonded onto opposite axial extremes of the stack having their axially exposed surfaces wiped with a film of silicone compound possessing the capability for inhibiting bonding. A liquid adhesive is coated onto surfaces shaped to mate with the axially exposed surfaces and the mating surfaces are forcefully brought together by a stress rod reaching between the head and tail masses. After curing, a rigid joint is set up across the hard adhesive where it contacts the head and tail masses while adjacent unbonded joints are created across the silicone compound film to block the transfer of destructive stresses caused by ambient temperature and pressure variations.
