  • Patent number: 10614249
    Abstract: Embodiments enable a displayed webpage containing sensitive information to be accurately and efficiently sanitized. The sensitive information is contained within a text string of the webpage and displayed using a font specified in a style sheet. The text string that is to be sanitized is determined based on a tag for sanitization associated with the text string. When the tag is determined, the text string is rendered using a font from the style sheet that is not legible. Upon rendering, the text string of the webpage is redisplayed using the non-legible font, which effectively sanitizes the text string containing the sensitive information.

  • Patent number: 10583846
    Abstract: The present invention generally relates to a rail transport system having no internal drive, and in particular to an improved rail transport system for conveying bulk materials. The rail transport system includes horizontal and vertical drive stations that include a drive tire that rotates on a plane parallel to the track. In this arrangement, force is applied on a different plane than earlier systems, and the reaction force is separated out of the tensioning device. The improvements of the drive stations provide for a reduction of steel used in the system, improved manufacturability and, therefore, reduction in system component costs as compared to previous drive stations. Moreover, the drive stations allow for improved maintainability and access to the drive tires.
