  • Patent number: 5806434
    Abstract: A suspension conveyor and sorting installation for the sequential sorting of individually conveyed objects. The installation includes two parallel conveyor paths arranged side by side and driven in opposite directions. Independent roller devices carry objects to be sorted and are conveyed by getting coupled to pushing members. Stop members stop the roller devices on associated conveyor paths, so that the roller devices can be uncoupled from the pushing members. A transfer apparatus is provided between the conveyor paths at a distance from their respective ends, for transferring the objects conveyed along the conveyor paths, from one conveyor path to the other conveyor path. Finally, a sorting controller, connected to the transfer mechanism and the stop members, controls the sorting of the conveyed objects such that the objects are sorted while remaining on the conveyor paths.

  • Patent number: 5575215
    Abstract: A bypass for a car of a circuit cable railway system, which is positioned at a turn-about station of the system between the incoming and outgoing lines of at least one revolving conveying cable. The bypass includes coupling points, disposed on incoming and outgoing tracks of the station, at which the car is decoupled from the conveying cable when entering the station and coupled to the conveying train cable when exiting the station. A conveying apparatus drives the car, which has been decoupled from the conveying cable, at a feeding velocity around the station on a station track, and accelerates movement of the car on the station track to enable the car to recouple with the conveying cable at the coupling point when exiting the station. The station track has an incoming portion at the location where the car enters the station and an outgoing portion at a location where the car exits the station.

  • Patent number: 4715361
    Abstract: Apparatus for passively exercising the human extremities includes an elongate track (16) comprising a tubular housing (46) having a slot formed in the bottom thereof. A lead screw (62) is longitudinally disposed in the housing and a carriage (26) is threadably engaged with the lead screw (62). The carriage (26) is connected to the extremity to be exercised, so that upon movement of the carriage (26) back and forth along the elongated track (16) the extremity is moved through a pre-determined range of motion. Stop members (28) are positionable on the housing in the path of movement of the carriage (26). Engagement of the carriage (26) with the stop member (28) effects longitudinal shifting of the lead screw (62). Longitudinal shifting of the lead screw (62) actuates switches (110) which reverse the direction of rotation of the lead screw (62) thereby reversing the direction of movement of the carriage (26).
