  • Publication number: 20150320437
    Abstract: An apparatus comprises a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide comprises a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section comprises a plurality of body portions aligned along the longitudinal axis and a flexible locking member. The flexible locking member is operable to secure the body portions in relation to each other and in relation to the shaft. The end effector comprises an ultrasonic blade in acoustic communication with the waveguide. The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis.

  • Patent number: 5034148
    Abstract: This invention relates to a cleansing composition comprising a detergent and an acid salt and/or a complex of formic acid which has more than one chemical equivalent of formate ion per cation other than hydrogen. The compositions are suitable for cleaning stains and iron oxide deposits caused by the braking mechanism of railway carriages.

  • Patent number: 4261755
    Abstract: This invention relates to the use of sodium, calcium and ammonium salts of formic acid as early strength developers and setting accelerators in hydraulic cements, concretes, mortars and plasters. The salts used are acidic salts containing between 1.5 and 5 moles of the formate ion per mole of the cation. These salts have much greater solubility and are more effective than the corresponding calcium salts, particularly under low temperature conditions.
