Abstract: An extender for hydraulic jacking systems. It increases the clearance under the raised object for increased access and mobility. It is easily installed and removed from commercially available systems.

Abstract: A compliancy joint for a robot has six degrees of compliancy freedom and comprises a housing having an inner ring. A float block is movably disposed in the interior of the housing and a plurality of circumferentially arranged pneumatic cylinders on the housing apply force circumferentially to the float block. Sensors are used to detect when the float block is near its compliancy limit and a controller is operatively connected to the sensors and the cylinders for preventing the float block from reaching its compliancy limit. This joint is able to break away from the robot should the robot exceed the device's compliancy limit, preventing damage to the robot and robot end of arm tooling.

Abstract: This invention pertains to an automatic method and apparatus for ascertaining the mass-moment of a blade of a jet engine. It encompasses robotic means to transport the blade from its loading station to the weighing station where its mass-moment is computed via a computer. Afterwards, the blade is returned to the loading station where the cycle begins over again.

Abstract: This invention pertains to an automatic apparatus and method for determining the mass-moment of a blade of a jet engine. It encompasses an elongated weighing beam that is lifted up off both the weighing scale and a fixed fulcrum block during the loading and unloading of the blade with respect to the weighing beam. When measurements are to be taken, the weighing beam, with blade attached, is lowered onto the scale and the fixed fulcrum block. The value measured by the scale is sent to a computer for calculation of the blades' mass-moment.

Abstract: This invention pertains to a robotic tool end assembly used to transport a blade of a jet engine to a specific workstation and then to transfer this blade to this workstation. It encompasses gripping means to grip the blade and coupling means that couple with the workstation prior to the exchange of the blade between the workstation and this robotic tool end assembly.
