  • Floating nut and carriage assembly
    Patent number: 9334937
    Abstract: A linear guide including a guide rail, a carriage, a drive screw and a connection arrangement is provided. The guide rail defines a linear travel path. The carriage is mounted to the guide rail for motion along the linear travel path. The drive screw is operably mounted to the guide rail. The connection arrangement couples the drive screw to the carriage to convert rotary motion of the drive screw to linear actuation of the carriage along the linear travel path. The connection arrangement provides a single degree of linear freedom between the drive screw and the carriage in a direction that is generally perpendicular to the linear travel path. The single degree of linear freedom permits relative motion between the screw and the carriage to relieve internal binding between the relative components.

  • Method of calibrating a magnetic character bearing document
    Patent number: 5488293
    Abstract: A method of calibrating a document having a magnetic character on the document comprises measuring by testing equipment, magnetic flux level of a known current passed through a specified conductor to establish a first signal having a first signal strength represented by a unit value, passing the document through the testing equipment to provide a second signal having a second signal strength produced by magnetic flux of the character and assigning a value to the second signal strength in comparison to and shown in units as a percentage of the unit value of the first signal strength.
