  • Publication number: 20240304881
    Abstract: Lithium-ion batteries are recycled by a series of physical and chemical processes. Used batteries are comminuted, and then the shredded material stream is further processed to create black mass for further refinement into constituent materials that are used in the production of new batteries. Black mass is produced from a liquid stream and a solid stream. The method is adaptable to different types and sizes of lithium-ion batteries and is designed to minimize waste and optimize material recovery.

  • Patent number: 9789802
    Abstract: The present invention is a system for high capacity hydraulic truck loading. The system includes a frame to which a hydraulic cylinder is pivotably at a first cylinder pivot. The hydraulic cylinder, when actuated, applies a force to an L-shaped primary arm at a second cylinder pivot. This force cause the primary arm to pivot around various pivot points in a linkage assembly made up of the frame, a U-shaped secondary arm and a plurality of stabilizer arms. The respective positions of the connecting pivots and linkages allow the primary arm to raise or lower an item for loading without contacting a truck tailgate or bumper.

  • Patent number: 5967265
    Abstract: An inclined lift device for transporting an individual passenger includes a rail, a carriage adapted for being movable along the rail, a drive mechanism coupled to the carriage for moving the carriage along the rail, and a support secured to the carriage for supporting the individual passenger. The rail has at least one retaining surface and a guide surface. The carriage includes a housing pivotally coupled to the rail about an axis spaced from the guide surface, a retaining mechanism pivotally coupled to the housing about the axis and a follower coupled to the housing and spaced from the axis by a predetermined distance. The retaining mechanism engages said at least one retaining surface of the rail to retain the carriage relative to the rail during movement of the carriage along the rail. The follower engages the guide surface to pivot the carriage about the axis based upon a distance between the guide surface and the axis.
