  • Catalyst removal workstations and systems incorporating same for tubular reactors
    Patent number: 6360786
    Abstract: A system is used for removing catalyst from a tubular reactor vessel. A power box with a 110 volt to a 12 volt DC transformer is mounted outside the vessel and connected to a 110 volt power supply. An air manifold, also mounted outside the vessel, is connected to a high-pressure air supply and connects to several valves with a separate connection to the power box. Several workstations are placed on the tube sheet within the vessel. The workstation has a frame, a drum and reel assembly mounted on the frame along with a 12 volt DC motor. An air lance hose passes into the drum and reel assembly and, at the other end, connects to an air lance and vacuum assembly. A high pressure air hose connects the drum and reel assembly to one of the valves located outside of the vessel. A controller connects to the 12 volt DC motor to power the drum and reel assembly. The controller is also connected to the power box located outside the vessel and to a foot control. A seat is mounted on the drum and reel assembly.

  • Catalyst unloading device
    Patent number: 6182716
    Abstract: An electric motor is operatively connected to a reel for selectively storing, paying out, and rewinding an air lance of a device for unloading catalyst from tubular reactors. The electric motor powered reel provides improved on/off control of the air lance mounted on the reel, a braking force during withdrawal of the air lance from the reel, constant speed operation during rotation of the reel, and avoids the problem of lubricant contamination of the catalyst and reactor tubes.

  • Heat pipe
    Patent number: 4108239
    Abstract: A heat pipe is disclosed which carries an evaporable working fluid and which includes a wick. More particularly, in accordance with the invention the wick comprises a first layer having a small-pore structure and disposed adjacent the vapor space within the pipe and a second layer having a large-pore structure and disposed adjacent the first layer.

  • Cooling arrangement for flat semiconductor components
    Patent number: 3942586
    Abstract: An improved cooling arrangement for flat semiconductor components such as disc-type thyristors in which the semiconductor component is clamped between two solid cooling elements with each cooling element carrying at least one heat pipe with attached cooling fins and in which a plurality of such cooling arrangements rotationally displaced are combined in a column-like cooling stack to achieve equally good cooling for all heat pipes.
