A lift assembly including an article to be lifted between a lowered position and a raised position, a flexible drive element coupled to the article and defining a longitudinal axis, a power mechanism coupled to the flexible drive element, a drum powered by the power mechanism and dimensioned to facilitate winding of the flexible drive element onto the drum, and a cable keeper providing a force on the flexible drive element to bias the flexible drive element toward the drum.

Lift assembly systems and methods

A lift assembly includes an article to be lifted between a lowered position and a raised position, a drive element coupled to the article, a power mechanism coupled to the drive element, and a power transfer mechanism coupled between the power mechanism and the drive element. The power transfer mechanism includes control electronics having a first upward limit switch adapted to deactivate the power mechanism when the article is lifted to a first upward height, and a second upward limit switch adapted to deactivate the power mechanism when the article is lifted to a second upward height higher than the first upward height.

To address the problem of flush fluid leakage under normal operating conditions in rotary machinery, an improved pack-box has been conceived. The pack-box has a rotary bearing concentrically disposed within the pack-box, wherein a circumferential segment of the rotary bearing is circumferentially fixed within the pack-box. The pack-box further comprises a wall-step that defines at least a first thermal expansion channel and an inner wall that defines at least a second thermal expansion channel.

A reactor vessel including: a mixing chamber having a vertical length, an upper inlet, and a lower outlet; and a vertically oriented paddle within the mixing chamber and having a cross-sectional shape of a hydrofoil, wherein the paddle moves with respect to the mixing chamber.

A lift assembly comprising an article to be raised and lowered, a cable coupled to the article and defining a longitudinal axis, a power mechanism coupled to the drive element, a drum powered by the power mechanism, a cable keeper biasing the drive element toward the drum, a keeper shaft providing lateral movement of the cable keeper, and an encoder mounted for rotation with the keeper shaft. The encoder provides information regarding the position of the article. The lift assembly can also include a load cell assembly including a load cell housing, a load cell member contacting the drive element and movable relative to the load cell housing, and a load cell sensor coupled to the load cell member and operative to provide an output corresponding with a load on the drive element. The load cell member can be mounted for movement laterally relative to the longitudinal axis.

A thermoplastic molded housing has a cylindrical bore with axial grooves and inclined camming surfaces extending about the bore surface. A plastic molded vial for receiving injectable fluid in a cavity receives a plunger therein for dispensing the fluid and for displacing the vial. The vial has a ratchet member with fixed ratchet teeth and tabs about its circumference which tabs and teeth form camming surfaces which cooperate with the housing camming surfaces. The tabs are aligned for reciprocating in the housing bore grooves. A ring is secured captured to the vial for rotation about the vial and for limited axial displacement along the vial longitudinal axis. A spring urges the ring and vial to the retracted position. The ring has tabs with camming surfaces for selectively engaging the grooves and the camming surfaces of the ratchet member tabs, ratchet teeth and housing bore camming surfaces to selectively position the vial and the needle attached thereto from a needle retracted position enclosed by the housing bore to an extended needle use position and for retracting the needle and vial to a permanent retracted position in response to depression of the plunger and vial or displacement of the vial alone and to the spring force on the ring.
