  • Patent number: 9072637
    Abstract: A caddy for use with hospital staff or patients provides a rigid housing having a cradle which supports a container with at least one vertically and, preferably, at least one horizontally accessible compartments. A back of the cradle connects to a connector which connects to a hospital bed rail at a pivot to maintain the container in a pre-determined relationship while the rail is angled relative to a horizontal surface. The container is preferably removable relative to the cradle.

  • Patent number: 5914055
    Abstract: A system for repairing worn, distorted, cracked, or degraded portions of high temperature rotors such as those used in high-pressure and reheat steam turbines is disclosed. The repairs are applicable to low alloy steels generally described in ASTM Specification A-470 classes 3, 7, and 8. Explicit controls on the welding process, the welding consumables, and the placement of the weld fusion line are disclosed. For the welding process, a novel staging of the "relative heat input" for applying the initial cold wire gas tungsten arc weld (GTAW) buttering layer is disclosed. Significantly, the optimum weldment properties are achieved in the cold wire GTAW by utilizing a lower heat input for the crucial second layer relative to the first layer. Faster deposition or weld build-up is achieved over the buttering layer by applying the balance of welding through utilization of the hot-wire GTAW process.
