  • Patent number: 8714081
    Abstract: A safety device for a press having a head for applying force, a single fixed pressure source for actuating a low force pressure driven actuator and a high force pressure driven actuator for the head, wherein the operation of the head is limited to only with the low force actuator until the head is in a safe position, when the head is determined to be in a safe position the high force actuator's use is permitted.
    Type: Grant

  • Patent number: 8113258
    Abstract: An ultrasonic welding assembly is disclosed. The assembly includes an ultrasonic welder having nodal horn support for improving transmission of transducer energy to the weld comprising an acoustical tool having a horn; a weld tip on the end of said horn; and at least two nodal mounts which are in contact with and axially and radially support said horn. The horn self-aligns in housing by sitting a housing-key within a keyway in the horn. The weld tip self aligns by sitting the keyed tip in a keyway of the horn.

  • Patent number: 6159176
    Abstract: An improved ultrasonic surgical instrument is disclosed having a design that extends horn or tip life and minimizes instrument breakage and disintegration during use. The instrument comprises an ultrasonic tip having a distal working end and a metal sheath around the tip; the tip further having projections located in the vicinity of nodal points near the tip working end, said tip radially extending from the tip towards the sheath so as to provide the tip with radial inward support. The instrument can further comprise said tip with a substantially flat or convex end and said sheath with an inwardly projecting portion located distally of said tip projection and extending sufficiently radially inward so as to capture the tip with its projection should a tip break occur.
