Articulated seal puller system
A tool is formed of an upper component and a lower component. An intermediate component is formed of a first plate and a parallel second plate. The first plate and the second plate span the lower end of the upper component forming an upper pivot point and span the upper end of the lower component forming a lower pivot point. A foot is integrally formed with and extends r the lower component. A handle is formed of a cross piece with a central extent from the lower component adjacent to the lower end of extent central extent being attached to the upper end of the upper component. |

Ratcheting box torque wrench
A ratcheting box torque wrench is provided. The wrench includes a head and a handle connected to the head. The head has a slipping torque limiter that applies torque to a fastener in a first direction (T) up to a torque limit before slipping in the first direction (T) and ratchets in a second direction (R). |

Pushing lever structure of ratchet wrench
A pushing lever structure of a ratchet wrench is provided. The ratchet wrench has a head portion. A ratchet gear, a toothed element, and a pushing lever are mounted in a receiving space of the head portion. A rear peripheral surface portion of the toothed element is provided with a recess. A pushing block extending forward from the pushing lever extends into the recess of the toothed element. When rotated, the pushing lever can move the toothed element effectively because it is the pushing block of the pushing lever that drives the toothed element into displacement. The bottom side of the head portion is mounted with a cover plate, and the bottom end of the pushing lever is pivotally provided on the cover plate to enhance the rotation stability of the pushing lever. |

Supporting machining workpieces
A workpiece support includes a workpiece support element and a suction device. A workpiece is mounted on a workpiece side of the workpiece support element during machining. Towards a remote lower side, the workpiece support element is permeable to a waste air flow loaded with machining-related emissions. The suction device includes a vacuum generator and a suction line. The vacuum generator is configured to generate the waste air flow flowing from the workpiece side to the lower side, to suck off the waste air flow into the suction line in a flow direction and to subsequently discharge the waste air flow via the suction line. The suction line has a suction opening having a flow cross section which can be passed by the waste air flow in the flow direction. An opening width of the flow cross section and/or a position of the suction opening can be variably adjusted. |

Bias device for biasing a gripping device including a central body and shuttles on the working arms
A device comprising: (a) a first working arm; (b) a body; (c) a shuttle, and (d) a bias device; wherein the bias device biases the first working arm relative to the body when the shuttle is in a first position, and wherein the bias device is free of biasing the first working arm relative to the body when the shuttle is in a second position. |

Dual sided shot peening of BLISK airfoils
Dual sided shot peening system includes pressurized air supply in communication with independently controllable first and second air pressure regulators in communication with first and second shot supplies and independently controlled first and second shot flow control valves disposed between first and second nozzles and the shot supplies. Computer may be in control of regulators and valves. Nozzle supports may fixedly or movably support nozzles during shot peening. The system may be used for simultaneously shot peening first and second sides of a portion of a workpiece such as airfoils of a BLISK. First and second streams from first and second nozzles may have different properties and may be varied during shot peening. |
