Abstract: ABSTRACT     A printer includes a print mechanism for performing printing operations and a print medium feeding mechanism for feeding a print medium past the print mechanism so that printing operations can be performed on the print medium.          The print medium feeding mechanism includes a forward feed apparatus located downstream of the print mechanism for feeding the print medium in the forward direction past the print mechanism and a print medium tensioning apparatus.  A reverse drive is also included.  The tensioning apparatus includes at least one pair of pressure wheels rotatable mounted on the frame and located on opposite sides of a print medium being fed by the forward feed apparatus and means for restricting the rotation of at least one of the pressure wheels, whereby the pressure wheels exert a retarding force on the print medium tending to tension the print medium.  Each pressure wheel is constructed so that it is flexible in the axial direction so as to permit lateral movement of a print medium as it passes between the pair of pressure wheels.

Abstract: ABSTRACT OF THE DISCLOSURE       An  optical  recording  disk  comprises  a  track divided  into sectors and  having  a  longitudinal  axis. Areas  on  this  track   for  writing   data  using   a predetermined increment alternate with prewritten marker areas.   Each of these comprises at least two patterns having leading and trailing edges.  Part of at least one of these patterns is offcenter relative to the  track axis and associated with at least one edge of a pair of leading and trailing edges combined with another pair of leading and trailing edges to define along the axis two predetermined distances.   Each of  these distances  is between two consecutive multiples of the data writing increment.    The  patterns  are  adapted  to  be  scanned optically in succession by a read spot  to detect any track following error, by virtue of interaction of the read spot with at least the offcenter pattern part, and with  reference  to  a  timebase  synchronization  signal resulting  from  interaction of the  read  spot  with  at least  two  leading  edges  and  at  least  two  trailing edges.

Abstract: Abstract An abrasive surfacing machine is disclosed having a surfacing head which utilizes a large disk with a fibrous web abrasive medium.  The disk is sized to be at least as large in diameter as the width of the under-lying workpiece conveyor, and is disposed in parallel relation to the workpiece conveyor.  As such, any work-piece entering the abrasive surfacing area will first be engaged by the abrasive medium moving in a first direc-tion, and as the workpiece traverses the disk rotational axis movement of the abrasive medium is in the opposite direction.  The multidirectional movement of the abra-sive surfacing machine is particularly suited for deburring and polishing small parts even where the sur-face involved includes recesses, holes, grooves, chan-nels, bores, slots and other irregularities.

Title: Corona charging device
Inventor: GUNDLACH ROBERT W
IPC: G03G15/02

Granted: 1988-12-28
Abstract: ABSTRACT OF THE DISCLOSURE A minature coronode charging device comprising a plurality of coronode wires that are slanted with respect to the direction of travel of a charge receptor in order to reduce the effective distance between "hot spots" in the wires and thereby insure uniform charging of the receptor. The length of coronode wires between support points and their conducting contacts is very small, thereby eliminating sagging, singing, tensioning and capacitance problems when providing a corotron charging device of unlimited length. Individual high impedance to the plurality of coronode wires is provided in order to limit the amount of current passing to each of the wires from a high voltage source and thereby reduce the possibility of arcing and damages to the charge receptor. Spacing between corona wires and the charge receiving surface is small to provide low corona threshold and self-limiting charging.
