A vacuum device for a material handling system includes a vacuum device body and a sealing element. The vacuum device body has a vacuum passageway in which H vacuum is generated in response to activation of a pressurized air supply that forces pressurized air through a venturi device. The sealing element moves to a sealing position to substantially seal the vacuum passageway when the air supply is activated, and is urged toward the sealing position via pressurized air that is diverted from an inlet of the vacuum device to the sealing element. The sealing element moves to substantially vent the vacuum passageway when the air supply is deactivated. The vacuum passageway may be in fluid communication with a vacuum cup, which seals against the object when the sealing element is at the sealing position and the vacuum generating device generates at least a partial vacuum in the vacuum passageway.

A hatch power lift and locking system may include a hatch configured to cover an opening, the hatch being pivotable about an axis between a closed position and an open position. The assembly may also include at least one latch dog attached to the hatch, and at least one dog catch pin engaging with the at least one latch dog in the closed position. The at least one latch dog may include a latch slot for receiving the at least one dog catch pin, and a latch catch for engaging the at least one dog catch pin. The assembly may further include an actuator configured to move at least a portion of the hatch between the closed position and the open position.

A sliding power lift and locking assembly for lifting and locking an object includes a motor, a first drive shaft, a first drive block assembly, a first drive housing, and a link arm. The first drive shaft has a body and a cylindrical axis and is rotationally driven by the motor. The first drive block assembly includes an aperture configured to engage the body of the first drive shaft, a latch dog with a first slot configured to engage a dog catch pin associated with the object, and a slider. A portion of the first drive housing and a portion of the first drive block assembly are provided in a track of the first drive housing, and the track of the first drive housing is configured such that the first drive block assembly is configured to move in a path relative to the first drive housing. The link arm includes a first end and second end. The first end of the link arm is configured to move with the slider of the first drive block assembly, and the second end of the link arm is configured to connect to the object.

A retractable convertible top for a pleasure craft, including a canvas type fabric and stowable linkage mechanism, is described. This convertible top may be fully deployed and retracted automatically to provide a quick and efficient means of providing shelter for the open cabin of a pleasure craft while still allowing easy entrance and egress from the cabin when the top is fully deployed. The convertible top may be fully stowable within a small volume storage bin with watertight covers. The stowage bin may be integrated into the craft. The craft's existing hydraulic and control systems may be utilized to automatically deploy and retract the convertible top.

A method utilizing a vacuum cup for a material handling system including a body portion and a perimeter seal that functions to substantially seal against an object. Engaging the vacuum cup with an object to substantially seal the cup perimeter against the object. Substantially closing a relief port, via the sealing member, as the vacuum cup is engaged with the object. Transporting the object to a targeted location while the perimeter seal is substantially sealed against the object. Moving the vacuum cup in a direction generally away from the object at the targeted location. At least partially opening the relief portion to at least partially vent the cavity from the vacuum cup. Removing the vacuum cup from the object.
