Certain embodiments described herein are directed to time of flight tubes comprising a cylindrical tube comprising an inner surface and an outer surface, the cylindrical tube comprising an effective thickness and sized and arranged to couple to and support a reflectron assembly inside the cylindrical tube. In some configurations, the cylindrical tube further comprises a conductive material disposed on the inner surface of the cylindrical tube, the conductive material present in an effective amount to provide a field free region for ions when the conductive material is charged.

Time of flight tubes and methods of using them

Certain embodiments described herein are directed to reflectron assemblies and methods of producing them. In some configurations, a reflectron comprising a plurality of lenses each comprising a planar body and comprising a plurality of separate and individual conductors spanning a central aperture from a first side to a second side of a first surface of the planar body is described. In some instances, the plurality of conductors are each substantially parallel to each other and are positioned in the same plane.

Reflectrons and methods of producing and using them

The sheet capacity of a pivoting feed head is combined with a complimentary pivoting design for the paper tray lift, such that a large total capacity of sheets is attained within a compact space, while allowing the lifting mechanisms to be located outside of the perimeter of the paper tray.

Method to accommodate a large capacity of sheets in a feeder mechanism

A system and method for accumulation of media invention includes a series of upper and lower transport belts for feeding media seriatim along a path of travel. An accumulator pocket is positioned between the upper and lower drive belts along the path of travel. An upper and a lower accumulator ramp is positioned adjacent the accumulator pocket are moveable between a first position and a second position. The first accumulator ramp position is such that the lower ramp is positioned to engage media moved seriatim along the path of travel to guide the media to form a forward accumulation of media in the accumulator pocket. The upper accumulator ramp second position is such that the upper accumulator ramp is positioned to engage media moved seriatim along the path of travel to guide the media to form a reverse accumulation of media in the accumulator pocket. One or more rollers can be mounted to cooperate with the lower accumulator ramp and one or more rollers can be mounted to cooperate with the upper accumulator ramp to reduce forces which would tend to cause previously assembled media collations to shear apart during transport into the accumulator pocket. The upper and lower accumulator ramps may also be positioned to enable transport of media through the system without the accumulation of media in the accumulation pocket.
