20080253497 | UPPER INTERNALS ARRANGEMENT FOR A PRESSURIZED WATER REACTOR - In a pressurized water reactor with ail of the in-core instrumentation gaining access to the core through the reactor head, each fuel assembly in which the instrumentation is introduced is aligned with an upper internals instrumentation guide-way. In the elevations above the upper internals upper support assembly, the instrumentation is protected and aligned by upper mounted instrumentation columns that are part of the instrumentation guide-way and extend from the upper support assembly towards the reactor head in hue with a corresponding head penetration. The upper mounted instrumentation columns are supported laterally at one end by an upper guide tube and at the other end by the upper support plate. | 10-16-2008 |
20080279326 | NUCLEAR REACTOR DOWNCOMER FLOW DEFLECTOR - A nuclear reactor having a coolant flow deflector secured to a reactor core barrel in line with a coolant inlet nozzle. The flow deflector redirects incoming coolant down an annulus between the core barrel and the reactor vessel. The deflector has a main body with a front side facing the fluid inlet nozzle and a rear side facing the core barrel. The rear side of the main body has at least one protrusion secured to the core barrel so that a gap exists between the rear side of the main body adjacent the protrusion and the core barrel. Preferably, the protrusion is a relief that circumscribes the rear side of the main body. | 11-13-2008 |
20090052606 | NUCLEAR REACTOR INTERNALS ALIGNMENT CONFIGURATION - An alignment system that employs jacking block assemblies and alignment posts around the periphery of the top plate of a nuclear reactor lower internals core shroud to align an upper core plate with the lower internals and the core shroud with the core barrel. The distal ends of the alignment posts are chamfered and are closely received within notches machined in the upper core plate at spaced locations around the outer circumference of the upper core plate. The jacking block assemblies are used to center the core shroud in the core barrel and the alignment posts assure the proper orientation of the upper core plate. The alignment posts may alternately be formed in the upper core plate and the notches may be formed in top plate. | 02-26-2009 |
20090296877 | NUCLEAR REACTOR ALIGNMENT PLATE CONFIGURATION - An alignment plate that is attached to a core barrel of a pressurized water reactor and fits within slots within a top plate of a lower core shroud and upper core plate to maintain lateral alignment of the reactor internals. The alignment plate is connected to the core barrel through two vertically-spaced dowel pins that extend from the outside surface of the core barrel through a reinforcement pad and into corresponding holes in the alignment plate. Additionally, threaded fasteners are inserted around the perimeter of the reinforcement pad and into the alignment plate to further secure the alignment plate to the core barrel. A fillet weld also is deposited around the perimeter of the reinforcement pad. To accommodate thermal growth between the alignment plate and the core barrel, a gap is left above, below and at both sides of one of the dowel pins in the alignment plate holes through which the dowel pins pass. | 12-03-2009 |
20100119030 | NUCLEAR REACTOR INTERNALS ALIGNMENT CONFIGURATION - An alignment system that employs jacking block assemblies and alignment posts around the periphery of the top plate of a nuclear reactor lower internals core shroud to align an upper core plate with the lower internals and the core shroud with the core barrel. The distal ends of the alignment posts are chamfered and are closely received within notches machined in the upper core plate at spaced locations around the outer circumference of the upper core plate. The jacking block assemblies are used to center the core shroud in the core barrel and the alignment posts assure the proper orientation of the upper core plate. The alignment posts may alternately be formed in the upper core plate and the notches may be formed in top plate. | 05-13-2010 |

20080223661 | Grease Guide - A trough for use on wiping bar assembly of a rail lubrication system, wherein the wiping bar assembly includes a manifold body and a flow passageway having an exit end at least partially defined in the manifold body. The trough includes a body having a first section and a second section extending away from the first section, wherein the first section of the body is positioned adjacent the exit end, and wherein a mat is provided within the trough. | 09-18-2008 |
20100224449 | Modular Lubrication Unit - A modular lubrication unit for a rail lubrication distribution system includes a tank, a pump assembly, and a controller. The pump assembly is in fluid communication with the tank and the controller is in communication with the pump assembly for controlling the pump assembly. The controller is enclosed within a panel and the tank is self-contained and movable relative to the panel. | 09-09-2010 |
20100300810 | Top of Rail Foam Bar - A rail applicator assembly includes a rail having a head portion, a base portion, and a web portion extending between the head portion and the base portion. The head portion defines an outer surface. An applicator for applying a friction modifying material to the surface of the rail includes a foam body and an applicator support. The foam body is secured to the applicator support and defines a flow passageway that extends through the foam body for friction modifying material to flow through. | 12-02-2010 |
20120126073 | Wiping Bar Quick Clamp - A clamp device for mounting a rail device onto a railroad rail includes a clamp body having an upper section and a lower section. The clamp body defines a recess portion between the upper and lower sections and a bore extending through the lower section of the clamp body. A bolt having a first end and a second end extends through the bore of the clamp body. The clamp device also includes a quick release mechanism having a lever arm and a cam member pivotally connected to the second end of the bolt. The lever arm is connected to the cam member and has a clamped position and a released position whereby pivoting the lever arm from the released position to the clamped position draws the first end of the bolt and the clamp body together. | 05-24-2012 |
