Handle for an ultrasonic insert tool

A magnetostrictive transducer including a plurality of magnetostrictive laminates each having a first end and a second end. The first and second ends of the laminates include openings. The laminates are arranged in a stacked configuration and bonded together by solder at the first and second ends. At the first and second ends the solder extends through the openings of the laminates forming a solder bar therein. The solder bars bond the laminates together with increased mechanical strength and also provide increased electrical contact between the laminates.

Laminated magnetostrictive transducer

A vibration cancellation device is provided for an air motor with a reciprocating drive piston. The device consists of an anti-phase piston which is axially aligned with the drive piston and reciprocates in the opposite direction of the drive piston. In one embodiment, the stroke of the anti-phase piston is adjustable to permit optimizing its vibration cancellation characteristics.
