  • Patent number: 6092519
    Abstract: A case for heating sample containers during transport, where the case has a housing that containing thermal insulation and a disposable heating material that generates heat by chemical reaction with oxygen. Closeable apertures allow control over the access of oxygen to the heating material, and thereby over the rate of reaction. A method of portably heating a sample cylinder is also disclosed.

  • Patent number: 5959305
    Abstract: A charge neutralization monitor monitors the operation of a charge neutralization system for an ion implantation system. The charge neutralization system produces neutralizing electrons in a region through which an ion beam passes in treating one or more workpieces. The charge neutralization monitor applies a suitable voltage to a target electrode positioned to collect neutralizing electrons produced by the charge neutralization system. The charge neutralization monitor then determines the available neutralizing electron current that may be produced by the charge neutralization system by monitoring the current flowing through the target electrode.

  • Patent number: 5316288
    Abstract: A lateral sheet registering device for registering sheets transported along a path including a lateral registration edge positioned along the path. An apparatus is provided for driving sheets laterally and along the path so that a lateral edge of a sheet is registered along the lateral registration edge and so that sheets are transported along the path. The invention further includes a gate positioned in the path opposite said lateral registration edge for engaging an edge of a sheet to oppose rotation of such sheet in the path. The gate also is positioned to permit unimpeded transport of the lead edge of a sheet so that larger sheets are transportable within the path.

  • Patent number: 5228671
    Abstract: A sheet feeder with single sheet bypass sheet feeding capability has a sheet support platform for supporting a stack of sheets, at least one sheet feed roll fixedly mounted on a rotatable shaft and having a segmented feed portion for contacting and feeding the top sheet in a stack of sheets and defining therewith a sheet feeding path, sheet registration rolls downstream of the feed roll, at least one sheet bypass registration finger upstream of the registration rolls and downstream of and freely mounted about the feed roll shaft in the sheet feeding path, a sheet bypass guide rotatably mounted about the sheet registration rolls, the bypass guide having an angled sheet entrance throat to center a sheet and guide the leading edge into said bypass registration finger, the feed roll being rotatable through an opening in the bypass guide from a nonfeeding, standby position where the segmented portion is on the side of the shaft opposite the sheet support platform and a sheet feeding position where the segmented po

  • Patent number: 5152520
    Abstract: A recording apparatus includes a two-piece universal non-dedicated high capacity feeder. The high capacity feeder has separate paper storage/handling and interface modules that enhance easy adaptation to most recorders by modification of only the interface module. Easy removal of the interface module from the cassette insertion slot of the recorder is made without disconnection of the paper handling module in order to make the slot available for any number of conventional cassettes.

  • Patent number: 5049947
    Abstract: An automatic printing machine which forms an image on a sheet substrate has a multi-mode sheet output station in the form of a brush decision gate having a bidirectionally rotatable cylindrical fibrous brush to direct sheets upwardly over the top of the brush in a first sheet transport path when rotated in a counter clockwise direction and downwardly under the bottom of the brush in a second sheet transport path when rotated in a clockwise direction, the brush being selectively rotated in a clockwise and counter clockwise direction.

  • Patent number: 4988087
    Abstract: A sheet stacker and an automatic printing machine containing a sheet stacker are provided comprising a generally horizontal stacking platform having an outboard and an inboard end, an arcuate turn baffle at the inboard end of the platform for guiding and turning sheets onto the platform having a convex side forming a drive nip with a sheet drive assembly comprising a rotatable dirve shaft having fixedly mounted thereto as least one cylindrical, compressible foam drive roll and least two cylindrical fiber brushes, the diameter of the fiber brushes being greater than the diameter of the foam drive rolls whereby the brushes when rotated urge the lead edge of a sheet being fed generally vertically downward toward the nip formed between the foam rolls and the baffle to enable the foam rolls to actively drive the sheet through the nip around the turn baffle onto the support platform toward the outboard end.
