| 20120060575 | AGRICULTURAL BLEND AND PROCESS OF FORMING AN AGRICULTURAL BLEND - The present intention relates to an agricultural blend and a method of forming an agricultural blend. The agricultural blend includes a sulfate source and calcium silicate or a by-product of slag, the slag being selected from the group consisting of steel slag, stainless steel slag, alloy steel slag, carbon steel slag, and phosphate slag. The method includes blending a sulfate source and calcium silicate. | 03-15-2012 |
| 20120004795 | DRONE TAMPER - A drone vehicle for performing maintenance on a railway system is provided. A drone vehicle control system is structured to utilize tie position data to position a drone vehicle workhead over at least a portion of a respective tie. The drone vehicle control system is further structured to actuate the drone vehicle workhead. The drone vehicle may be controlled by a drone vehicle control system linked, preferably by wireless communications, to a lead vehicle and a lead vehicle control system. The lead vehicle control system and the drone vehicle control system are structured to communicate with each other, with the lead vehicle control system providing the tie position data to the drone vehicle control system. | 01-05-2012 |
| 20110290464 | HEADER FOR HEAT EXCHANGER AND METHOD OF MAKING THE SAME - A header box for a heat exchanger assembly and the method of manufacture. The header box has a first header component and a second header component. The first header component has a first corner portion with a first wall and a second wall extending therefrom. The second header component has a second corner portion with a third wall and a fourth wall extending therefrom. Free ends of the first wall and the third wall cooperate to form a first seam which is welded to maintain the first wall in position relative to the second wall. The free ends of the second wall and the fourth wall cooperate to form a second seam which is welded to maintain the third wall in position relative to the fourth wall. The header box, with the first corner portion and the second corner portion, will withstand the stress concentrations associated with a flow of fluid in the header box. | 12-01-2011 |
| 20110203781 | MULTIPLE-RING HEAT EXCHANGER - The heat exchanger with a radial heat source has a first header, a second header, first tubes and second tubes. The first header is configured to allow liquid to enter and exit the heat exchanger. The second header is spaced from the first header and has at least one lower baffle provided therein. The first tubes extend from the first header to the second header, with the first tubes being spaced proximate to the radial heat source. The second tubes extend from the first header to the second header, with the second tubes being spaced from the radial heat source a greater distance than the first tubes. An enhancement device may be positioned in respective tubes of the first tubes to create a water vortex in the first tubes wherein boiling of the water in the first tubes is prevented. | 08-25-2011 |
| 20110132590 | HELICALLY WOUND FINNED TUBES FOR HEAT EXCHANGERS AND IMPROVED METHOD FOR SECURING FINS AT THE ENDS OF THE TUBES - A finned tube for heat transfer from one medium to a second medium, and the method of manufacture, is disclosed. A helical fin of the finned tube has an area of compressed fins positioned proximate an insertion section which has a metal tube exposed with the helical fin removed therefrom. The compressed fins are a portion of the helical fin which has been compressed so that the helical fin in the area of the compressed fins is more closely spaced than the remaining portion of the helical fin. A base portion of the helical fin in the area of the compressed fins is layered and compressed on itself and is compressed against the metal tube. The layers of the base portion are compressed together and to the metal tube of the finned tube, which causes the layers of the base portion to bind together and bind to the metal tube to prevent movement of the helical fin in the area of the compressed fins in a direction parallel to the longitudinal axis of the finned tube. | 06-09-2011 |
| 20110083578 | BATTERY-POWERED RAIL VEHICLE - A rail consist having at least one propulsion car having traction motors and at least one working car having working motors. Energy storage units are provided on the consist to provide power to the traction motors and the working motors. The energy storage units provide sufficient power for work mode, travel speeds and curve characteristics of the consist. The use of the energy storage units provides safety, environmental and operational benefits. | 04-14-2011 |
| 20110064273 | AUTOMATED TURNOUT INSPECTION - A method of inspecting a turnout of a track includes the steps of: capturing images of the components of the turnout; converting each image into a set of coordinates that traces the transverse cross-section of a rail profile; analyzing the rail profile to determine if the rail profile is a profile of arunning rail portion or a component. Upon determination that the image represents a component, taking measurements of the rail profile and applying virtual gauges to the rail profile to check for potentially dangerous conditions of the component; and generating a summary of each cross-section of the rail profile of the component indicating problem areas. The method is used for identifying certain classes of switch or turnout rail conditions which can lead to derailments, and for enhancing the turnout inspection approach currently used. The use of this method as an integrated part of the rail profile monitoring program will reduce reliance on field measurements and will also allow more frequent, comprehensive, and convenient analysis of turnout condition. | 03-17-2011 |
| 20100237857 | STRINGLINE AND CROSS-LEVEL GAUGE - A tool and method for inspecting a track having a first rail and a second rail. The tool has a first mounting device which is attached to a first rail of the track. A cord attached to the mounting device is tensioned and positioning the cord in a proper position, allowing an inspector to measure a first distance between a defined point on the cord and the first rail or the second rail to determine if anomalies are present in the track. | 09-23-2010 |
| 20100193733 | REGENERATED CALCIUM ALUMINATE PRODUCT AND PROCESS OF MANUFACTURE - The disclosed invention provides an improved method that utilizes a liquid ladle slag in combination with a crushed material, such as a refractory brick, and alumina ladle brick or an aluminum dross, to manufacture a calcium aluminate product that can be used in the steel refining process. | 08-05-2010 |
