Abstract: A hoist swivel shackle assembly used with others to hoist heavy objects such as dies and molds. The shackle includes a "U" shaped shackle member pivotal on a swivel body which is rotatable about an orthogonal axis on a base. Long term distortion of the shackle member is minimized by flanges on the ends of the legs of the shackle that slidably engage side bosses on the swivel body to absorb outward loading on the shackle. The shackle is pivoted to the swivel body member by a pair of pins with annular recesses, fixed in a pair diametrally opposite pin receiving bores in the swivel body member. These pins are held in the swivel body member by pressing a softened material into threaded bosses in the swivel body forcing it around the pins and into their recesses. Overloading the swivel shackle assemblies is minimized by an indicator that tells the operator when he has exceeded the safety angle of the shackle member.

Abstract: A rotor and stator assembly having a rotor and a stator with opposing surfaces defining an air bearing and an air dam of an aspirating face seal. In a first embodiment, the air bearing and the air dam are axially offset. In a second embodiment, the rotor has an axially extending protuberance located radially between the air bearing and the air dam. The axial offset and the protuberance each act to divert the air flow (e.g., compressed gas or combustion gases in a gas turbine or steam in a steam turbine) in a direction transverse to the air flow direction through the air bearing and the air dam, thus isolating the air flows from the air bearing and the air dam which improves seal performance.

Abstract: A sealing element for a packer or bridge plug or other downhole tool is illustrated which employs the use of back-up rings above and/or below a resilient seal. The various sleeves which are moved with respect to each other to compress the sealing element are made so that they are physically connected to the back-up rings. As a result, upon run-in, inadvertent compression of the seal is prevented and upon release, a physical separation occurs between the back-up ring and the sealing element, which allows the sealing element to expand and relax. Subsequent upward movement of the packer or bridge plug easily deflects the back-up ring since the sealing element is no longer in a compressed state directly underneath it. The packer then can easily be removed.
