    Abstract: Apparatus to feed sheets one at a time from a stack comprises a separator (10), rotating about a plane substantially normal to the stack (30). The separator rotation axis is tiltable in a first direction to contact the stack on one side to shingle the stack and move the top sheet rearwardly from under a restraint (51) and in a second direction to contact the stack on the other side to restore the stack to its unshingled state and move the top sheet over the restraint to a sheet feed roller (52).

    Abstract: A multibin, cut-sheet xerographic copier capable of operating in a simplex or a duplex mode, wherein sheets are fed from a selected sheet stack, one at a time, to the copier's transfer station, by a sheet feeding structure which includes a resilient combing wheel. The combing wheel is of a unique resilient construction, such that it exhibits a spring rate and damping factor which minimizes acoustical noise and enhances reliable, repeatable shingling of the top sheet of a stack to a closable sheet drive nip.

    Abstract: When transverse or slant tracks are recorded on magnetic tape, control of the position of the transverse transducer relative to the transverse track is critical in reading out the information in the transverse tracks. This control has two facets-finding a predetermined slant track and aligning the transducer with the slant track. The transverse track position sensing system shown herein provides control signals for these two functions. The position sensing is accomplished by use of a fixed head positioned relative to the path of the transverse transducer. The fixed head scans an area of the magnetic tape where each transverse track ends. Signals from the fixed head are analyzed to determine the track end position of each slant or transverse track. This information is, in turn, operated on to derive tape movement control information for the purposes of finding a slant track and aligning the track with the path of the slant track head. For greater accuracy in alignment, a second fixed head is provided for monitoring the other end of the transverse track to determine the angle of the slant track relative to the path of the slant track head. If the angles are not the same, corrections may be made by adjusting tape movement.
