A bearing assembly for a door linkage. The bearing assembly is placed about a shaft which runs through a central opening in an arm, and the arm rotates about the shaft. The bearing assembly comprises a central composition bushing, a boss which is rotationally locked with the arm, and a plate. The central opening is large enough such that all the elements of the bearing assembly can be removed without disassembling the arm. The plate retains the elements of the bearing assembly in place when the arm is in use. The plate may also provide torque transmission between the boss and the arm.

A relief valve has a closed position with a lid of the relief valve closing an opening of a storage tank and an open position with the lid pivoted away from the opening of the storage tank. A hand saver device for maintaining the relief valve in the open position includes a body comprising a U-shaped base plate having a central axis, a first end, a second end opposite the first end, a pair of lateral sides extending axially from the first end to the second end, and a recess extending axially from the first end. In addition, the hand saver device includes a pair of laterally spaced extension arms extending upwardly from the base plate. Each extension arm includes a throughbore extending laterally therethrough. Further, the hand saver device includes an elongate locking rod configured to be removably and slidably disposed in the throughbores of the extension arms.

A multifunctional storage counter includes a plurality of sides and a countertop positioned thereon to enclose a storage space on a floor upon which the storage counter rests, and where at least one of the plurality of sides is an openable side. The storage counter is configured to be moved along the floor to enclose a stationary item resting on the floor through the openable side and into the storage space.

A liquid tank configured to receive and store liquids, namely waste cooking oil. A tank configured to receive and store used cooking oil which preferably greatly enhances the ease and reduces the work required to dispose of undesired liquid. A tank configured to receive and store used cooking oil which may be entirely manually powered, manually powered and free of all motors and electrical components, may be operated by a powered device, may include a motor, or may be operated manually with a powered assist.

An automated top door system is provided for selectively closing and opening a cargo container for top loading of cargo. The top door system includes: a door panel, a rotary actuator driven by a motor, and a coupling means connecting the door panel and the rotary actuator. The door panel is a self-supporting structural lightweight door panel, and the coupling means, which is a separate part or is part of said door panel, is configured to provide rotational movement of the door panel around a rotational axis of the rotary actuator, in response to the rotary movement provided by the rotary actuator, when in use. A top-loadable cargo container includes an automated top door system; and uses of the automated top door system in transport vehicles.

A hopper of a pharmaceutical counter comprises a housing defining an interior sized to hold a plurality of pharmaceuticals. The housing defines an outlet in communication with the interior that is sized and shaped to permit the plurality of pharmaceuticals to move therethrough. The hopper also includes a baffle supported by the housing and disposed in the interior. The baffle is disposed between upper and lower ends of the interior. The baffle is arranged to support a portion of the plurality of pharmaceuticals above the baffle when the plurality of pharmaceuticals is held in the interior of the housing. This relieves the head pressure of the pharmaceuticals at the outlet.
