| 20080245931 | RAILWAY DIAMOND CROSSING - A modular railway diamond crossing incorporates sets of acute and obtuse angle castings. The rail connections to the castings have a fine taper to minimize joint impacts. The castings are spaced apart with a combination of rails and cast blocks. The outside block is a tapered design that maintains the flangeway and holds the castings and rails together. The inside block comprises a tapered common center casting. This unit also maintains the flangeway and a longitudinal distance between the castings. The center casting is a common part to all such crossings regardless of the crossing angle. | 10-09-2008 |

| 20110204153 | TRACK SYSTEM INCLUDING A GUARDRAIL - A track system for a railway system includes a base plate configured to be supported on a railroad tie. The system also includes a drive rail and a guard rail. The drive rail includes a head portion, a web portion, and a base portion.

| 20080240761 | Preconditioning Media Sheets To Reduce Transfer Voltage - Image transfer quality in an electrophotographic image forming device is improved by preconditioning a media sheet prior to transferring a toner image thereto at an image transfer station. The media sheet is preconditioned by applying a static charge to it. In a color DTM type device, the charge reduces the transfer voltages required at downstream image transfer stations to account for charge accumulated on the media sheet as a result of the image transfer process at upstream image transfer stations. The charge may be applied to the media sheet at a media sheet preconditioning element positioned upstream of an image transfer station. Alternatively, an initial charge may be applied to the media sheet at an image transfer station, without transferring a toner image to the sheet, and returning the sheet via a duplex path to positioned upstream of an image transfer station prior to an image transfer operation. | 10-02-2008 |
