  • Patent number: 7422675
    Abstract: A process for changing an anode of a cell for the production of aluminum by fused bath electrolysis including a plurality of anodes. According to the invention, an anode handling tool is used including a positioning device, a gripping device and a sensor detecting the vertical position of the gripping device, and the position sensor is used to measure the vertical distances traveled by the gripping device with respect to a reference level N. At least one sound or electromagnetic waves beam is then produced in a determined reference line or plane and the passage of the anode in the beam is used to measure the distances. The vertical position of the replacement anode in the cell is determined starting from the values obtained for the traveled distances and the replacement anode is put into this position in the place initially occupied by the spent anode.

  • Patent number: 7376473
    Abstract: An automatic LPG tank insertion apparatus for automobiles has a rotary column provided with a lift body, which has a support arm. A rotating plate is rotatably mounted to the support arm such that yaw, pitch, and roll of the rotating plate can be controlled separately. Clamping devices are mounted on the rotating plate to selectively clamp an LPG tank. A trunk opening area measuring device includes a base unit, a guide shaft, a ruler shaft, and an encoder. Trunk opening sizes and LPG tank dimensions for various vehicle models are stored in a control computer. When vehicle model is input to the control computer, yaw, pitch, and roll of the rotating plate are adjusted so that the LPG tank can be inserted into a vehicle trunk.

  • Patent number: 7293668
    Abstract: Manual boom lift apparatus and method involve a base having three support legs, a fulcrum configured to fixedly mount the legs, a boom member detachably mounted on the fulcrum, the boom member including on either end a counterbalance arm configured for detachably mounting one or more counterweights and a lift arm configured for hoisting a load, the lift apparatus enabling lift and placement of the load by pivotal manipulation of the boom member. Assembly of the detachable boom lift apparatus components is performed on the work site (in situ) and involves removably pinning aligned hole pairs to join the components and filling one or more containers with ballast to act as counterweights to the hoisted load. The apparatus is lightweight and durable, is easy to transport through small openings and can be used in rooftop installations of heating, ventilation, air conditioning and refrigeration (HVAC/R) equipment.

  • Patent number: 7290672
    Abstract: A crane tower device includes a basket that supports a tower crane and sits within a bay formed by the vertical columns of a building under construction. The basket and the tower crane are supported by support stubs that are attached to the vertical columns. Because the lateral and vertical load is principally distributed vertically to the vertical columns rather than horizontally, no reinforcement of the horizontal beams, floors or any other portion of the building structure are needed, which results in substantial cost savings.

  • Patent number: 7290671
    Abstract: A crane performs a self-assembling/disassembling operation using a hoisting winch, a hoisting rope, and a hanging hook, and includes a sheave device for guiding the hoisting rope on an upper portion of a lower boom. The sheave device includes a first sheave on a rear side of the lower boom and second and third sheaves on a front side of the lower boom. The second and third sheaves are arranged next to each other in the left-right direction, and the rope end is attached to the lower boom at a position near the top end of the lower boom. Accordingly, a lifting height in the self-assembling/disassembling operation is increased and the rope end can be attached/detached easily and safely from the front side of the lower boom when the lower boom is laid on the ground.
