  • Patent number: 11370603
    Abstract: A container including vertical side walls and a horizontal bottom wall coupled with the vertical side walls to define an interior volume. At least one vertical side wall includes an inner wall, a spaced apart outer wall, a top rail coupled with the inner wall, a bottom sill coupled with the inner wall, and a plurality of vertical supports coupled with the inner wall and extending between the top rail and the bottom sill. The inner wall has a first surface area and the outer wall portion has a second surface area that is less than the first surface area. A frame is coupled with the inner wall and supports the outer wall and extends between two of the plurality of vertical supports, the top rail, and the bottom sill. A panel is supported by the frame and disposed on the outer wall.

  • Patent number: 10967596
    Abstract: A baler and methods of operating a baler. The baler includes a housing defining an interior volume, the interior volume including a compression portion and a loading portion. The baler also includes a first closure movably coupled with the housing and operative to enclose the compression portion and a second closure movably coupled with the housing and operative to enclose the loading portion. Further, the baler includes a reciprocating compression assembly including a linear actuator and a platen operably coupled with the linear actuator. The platen is movable between a retracted position and an extended position in response to actuation of the linear actuator. Additionally, the first closure defines at least one recess therein and a lip extending about at least a portion of the at least one recess. The lip is operative to engage with compressible material disposed in the compression portion.

  • Publication number: 20200346850
    Abstract: A container including vertical side walls and a horizontal bottom wall coupled with the vertical side walls, the vertical side walls and bottom wall together defining an interior volume. At least one vertical side wall includes an inner wall portion, an outer wall portion spaced apart from the inner wall portion, a top rail coupled with the inner wall portion, a bottom sill coupled with the inner wall portion, and a plurality of vertical supports coupled with the inner wall portion and extending between the top rail and the bottom sill. The inner wall portion has a first surface area and the outer wall portion has a second surface area that is less than the first surface area. A frame is coupled with the inner wall portion and supports the outer wall portion, and the frame extends between two spaced apart vertical supports of the plurality of vertical supports, the top rail, and the bottom sill. A panel is supported by the frame and disposed on the outer wall portion.

  • Publication number: 20190275758
    Abstract: A baler and methods of operating a baler. For example, the baler includes a housing defining an interior volume, the interior volume comprising a compression portion and a loading portion. The baler also includes a first closure movably coupled with the housing and operative to enclose the compression portion and a second closure movably coupled with the housing and operative to enclose the loading portion. Further, the baler includes a reciprocating compression assembly including a linear actuator and a platen operably coupled with the linear actuator. The platen is movable between a retracted position and an extended position in response to actuation of the linear actuator. Additionally, the first closure defines at least one recess therein and a lip extending about at least a portion of the at least one recess. The lip is operative to engage with compressible material disposed in the compression portion.

  • Patent number: 6098775
    Abstract: A spud assembly is provided for use in a pneumatically actuated brake, clutch or other friction assembly. The spud assembly includes a spud and a washer that are configured to reduce axial and rotational movement of the spud within the friction assembly. The spud includes a body portion that is centered about a first axis and extends through an aperture in a holding plate of the friction assembly. The body portion includes an outer wall that defines a pair of diametrically opposed flats. The flats engage a corresponding pair of flats in the washer which is fixed against rotation relative to the friction assembly holding plate. The spud also includes a holding member, such as a circular flange, that extends radially outwardly from the body portion of the spud. The holding member abuts one side of the holding plate to reduce axial movement of the spud.

  • Patent number: 6029782
    Abstract: A brake having multiple actuators is provided. In one embodiment the brake includes a torque transmission assembly centered about a longitudinal axis, a hub that is rotatable about the axis, and first and second pressure plate assemblies that are axially movable relative to the torque transmission assembly and each other. The brake also includes a drive plate assembly responsive to axial movement of the first pressure plate assembly for braking the rotation of the hub relative to the torque transmission assembly. Springs urge the second pressure plate assembly in a first axial direction towards the first pressure plate assembly and the first pressure plate assembly towards the drive plate assembly thereby setting the brake. One actuator is used to urge the second pressure plate assembly in a second axial direction, opposite the first axial direction and away from the first pressure plate assembly, to thereby release the brake.
