  • Patent number: 7189033
    Abstract: Apparatus and methods for thrust sensing valves are disclosed. In one embodiment, an apparatus includes a housing including an input port and an output port and further having a mounting portion adapted to be coupled to a manufacturing tool. A supply member is operatively coupled to the housing to provide a flow of the pressurized medium into the input port of the housing. Finally, an elongated body is operatively coupled to the housing and moveable along an axis between a first position corresponding to a first pressure output from the housing and a second position corresponding to a second pressure output from the housing. The elongated body is biased into the first position and moveable into the second position in the presence of a thrust force on the mounting portion.

  • Patent number: 6971824
    Abstract: An apparatus for forming features in a workpiece is provided. The apparatus includes a nosepiece that engages a boss of a template and guides a tool member therethrough. The nosepiece includes a housing and an adjustable member positioned at least partially in an interior space of the housing. The adjustable member defines radial apertures that hold locking members such as spherical bearings. The locking members are configured to contact a tapered portion of the inner surface of the housing so that as the adjustable member is adjusted from an unlocked position to a locked position, the locking members contact the tapered portion of the housing and are urged radially inward to retain the boss.
