  • Patent number: 8479392
    Abstract: An automated tool and method for spacing a gap between the anti-vibration bars and the flow tubing in the bend region of a tube bundle of a U-tube steam generator, prior to welding, during manufacture. The tool comprises two toggle clamp elements attached to a scissors assembly, which are actuated by a linear drive motor in line with a force gauge, and coupled to a distance measuring device. The tool is operated by first attaching the toggle clamps respectively to two adjacent anti-vibration bars. A linear drive motor on the tool is then cycled and readouts of force and distance are plotted on a curve to determine the point of contact between the anti-vibration bar and the tube. The computer then automatically cycles the drive motor to adjust the gap to a desired range of position coordinates adjacent the point at which the curve markedly changes slope.

  • Patent number: 8443764
    Abstract: The arrangement is for positioning equipment in association with an opening in a boiler wall and has a rotation mechanism that rotates the equipment around a virtual rotation axis that lies within the outer wall of the boiler. During the use of a liquor spreader for the introduction of combustible material, the opening of the liquor spreader is arranged in the virtual center of rotation so that the point at which the combustible material is introduced is retained independently of the angle of rotation. The liquor spreader is united either with a glide device or the guide in the rotation mechanism.

  • Patent number: 8342139
    Abstract: Improvements in a catch and drain pan for a water heater is disclosed. The improvement includes an immersion resistant water heater support having a fixed or an adjustable leveling capability. The water heater Lifesaver support fits on the water heater support stand/area or inside a catch drain basing to elevate the water heater weight supporting base or metal legs above any standing water. The water heater Lifesaver support is also fabricated to level an uneven water heater to bring the water heater to a vertical orientation. The adjustable water heater support uses a sandwich of two supports in a cam configuration that are indexable in a plurality of finite engagement positions to slightly alter the vertical orientation of the water heater to account for variations and or horizontal orientation of the water heater mounting surface.

  • Publication number: 20120312253
    Abstract: A coil support member is attached to a coil inside a water storage vessel and includes multiple openings, insertion portions and a non-insertion portion. The openings are arranged in a lengthwise direction, and together with surrounding sites prevent contact between mutually adjacent loops of the tube of the coil and suppress contact between an inner surface of the water storage vessel and an outer surface of the coil. The insertion portions are formed between the openings and are inserted into an intra-coil space located radially inward of the outer surface of the coil. The non-insertion portion is positioned in an extra-coil space located radially outward of the outer surface of the coil. The insertion portions have insertion body portions preventing contact between mutually adjacent loops of the tube, and engagement portions contacting the tube from the intra-coil space and maintaining an inserted state of the insertion body portions.
