20100162705 | METHODS, SYSTEMS AND/OR APPARATUS RELATING TO STEAM TURBINE EXHAUST DIFFUSERS - An axial flow steam turbine flow path that includes a rotor and a casing defining the axial steam flow path; and a toroidal diffuser for diffusing the exhaust steam and turning the exhaust steam from a generally axial flow direction to a generally transverse or vertical and tangential direction; wherein the toroidal diffuser comprises a diffuser that, at least in part, incorporates the shape of a toroid or a section of a toroid; and wherein a toroid comprises the shape generated by revolving a circular or oval shape in three dimensional space about an axis coplanar with the circular or oval shape, which does not touch the circular or oval shape. | 07-01-2010 |
20100303619 | SHAPED AND STIFFENED LOWER EXHAUST HOOD SIDEWALLS - An arrangement and method adapted for providing a stiffened lower exhaust hood for a steam turbine. Sidewalls of the lower exhaust hood may taper inward between a horizontal joint and an inlet to a condenser for the steam turbine, providing an enhanced flow path for the exhaust steam. Stiffening of the sidewalls may be provided by stiffening bends, stiffening curvature, and external stiffening beams on the wall plate of the sidewalls of the lower exhaust hood, permitting reduction or elimination of structural supports within the exhaust hood, which degrade exhaust steam flow. | 12-02-2010 |
20110142605 | LOW-PRESSURE STEAM TURBINE HOOD AND INNER CASING SUPPORTED ON CURB FOUNDATION - A support arrangement for an exhaust hood. The inner casing in the inventive arrangement is supported directly by the curb foundation. As a result, the effect of pressure changes in the exhaust hood are eliminated and the effect of temperature changes of the exhaust hood are reduced relative to the positioning of the inner casing and the rotor within it. Shaft bearings may be outside the exhaust hood located in a standard directly on the foundation. Rotor end packing may also be attached to the standard. The exhaust hood can be a much simpler design with less structural supports and less fabrication time. Easier maintenance is facilitated because the shaft bearings are not tucked under the exhaust hood and the end packing can be removed without removal of a large section of the exhaust hood. | 06-16-2011 |

20140053394 | COOLING CIRCUIT FOR REDUCING THERMAL GROWTH DIFFERENTIAL OF TURBINE ROTOR AND SHELL SUPPORTS - A standard for supporting a turbine rotor and a turbine shell includes a bearing block including a housing enclosing bearing surfaces engageable by the turbine rotor. Turbine shell-arm supports are located on opposite sides of the housing, the turbine shell-arm supports each having a horizontal and one or more vertical surfaces adapted to be engaged by support arms of a turbine shell enclosing at least a portion of the turbine. An internal cooling/heating circuit is arranged to simultaneously cool or heat the bearing block and the turbine shell-arm supports to thereby reduce differential thermal growth characteristics of the turbine rotor and turbine shell. | 02-27-2014 |

20140161622 | PROPELLER - A propeller having a central post to which one or more blades are connected. The blades are disposed and configured to pull air in from the propeller's sides toward the propeller's axis of rotation to create pressure in an area in the vicinity of the center of the propeller's rotating axis for generating thrust. | 06-12-2014 |

20090118704 | INTERCONNECTED RIBBON COILS, MEDICAL DEVICES INCLUDING AN INTERCONNECTED RIBBON COIL, AND METHODS FOR MANUFACTURING AN INTERCONNECTED RIBBON COIL - Medical devices and methods for making and using the same. An example method for manufacturing a medical device, or one or more components thereof, may include providing a tubular member and laser cutting the tubular member to define an interconnected ribbon coil. An example medical device may include a core member and an interconnected ribbon coil disposed about a portion of the core member. | 05-07-2009 |

20120298726 | PLUMBER'S HEAT SHIELD - A plumber's heat shield comprises an arcuate metallic shell attached to a spring-clamp by means of an obedient shaft which enables the heat shield to be moved to any position relative to the spring-clamp. The arcuate shell is preferably formed from aluminum or other material having high infrared reflectivity. The obedient shaft is preferably formed from helically-wound steel spring outer sheath surrounding a ductile copper wire core. The spring steel outer sheath prevents the ductile copper wire core from being bent at too sharp of a radius (which would cause the ductile core to work-harden and fracture) while at the same time protecting the ductile copper wire core from the open-flame of the soldering torch. | 11-29-2012 |
20130306713 | METHOD OF FORMING A SOLDER JOINT - A method of forming a solder joint includes the steps of providing a heat shield member formed as an arcuate preferably metallic shell attached to a spring-clamp by means of an obedient shaft; attaching the spring clamp to a structure adjacent the solder joint; moving the heat shield member by bending the obedient shaft so that the heat shield member is positioned in a location spaced-apart from the solder joint with the concave surface of the heat shield member facing the solder joint; and applying heat from a torch to the solder joint from the side opposite the heat shield so that the heat shield reflects the heat back onto the solder joint. | 11-21-2013 |

20100270838 | WORKER'S BODY SUPPORT - A worker's body support includes a base assembly which is preferably made of two spaced channel members. An upright assembly also preferably made of two spaced channel members is pivotally mounted at its lower end to the base assembly. An angular adjustment structure is pivotally mounted to the base assembly and is selectively mounted to one of a number of different locations to the upright assembly to adjust the angular orientation of the upright assembly. A seat is mounted to the upright assembly and is movable to a plurality of different locations and orientations. | 10-28-2010 |
