Abstract: STUB DRAPER DRIVE FOR DRAPER HEADER                 ABSTRACT OF THE DISCLOSURE        A draper header attachable to a base tractor unit to harvest standing crop material and create a windrow by using draper conveyors to consolidate the severed crop material is disclosed wherein the draper header includes three draper sections, two of which are transversely shiftable to vary the location of a crop discharge opening.  The third draper section is fixed along the right side of the header and is rotatable to convey severed crop material inwardly away from the header sidesheet to displace the windrow away from any uncut crop material when the crop discharge opening is adjacent thereto.  Although the shiftable draper sections are rotatably driven by hydraulic motors, the fixed draper section is mechanically driven from a transverse drive shaft forming a part of the drive mechanism to the reciprocating cutterbar having a pair of counter-reciprocating sickles.

Abstract: Abstract Fingerprint Imaging Apparatus A fingerprint imaging apparatus for use in an identity verification system or the like.  The imaging apparatus includes a carriage rotatably mounted on a frame, with the carriage being driven by a stepper motor.  A transparent optical element having an arcuate recess for receiving a finger to be imaged is secured to the frame.  The rotatable carriage supports a light source and mirror which are positioned adjacent the optical element.  The mirror is positioned with respect to the source and optical element to receive light issuing from the element which originated from the souce.  The light is reflected by the mirror through a lens arrangement to a second mirror and then to a linear photo-diode array which are also mounted on the carriage.  When a finger is positioned in the recess of the optical element, the motor causes the carriage to rotate so that the finger is scanned by the light source.  The linear diode-array is periodically read out during the scan with the output of the array containing imaging data.  The data is then processed as required to accomplish the indentity verification function or the like.

Abstract: Mixing Systems Abstract Mixing systems for liquids having fibers sus-pended therein wherein the fibers tenaciously adhere to and accumulate on the leading edge of the impeller, thereby increasing the drag of the liquid on the impeller as it rotates and the consequent increase in the power required to rotate the impeller, is reduced. Axial flow of the liquid in a tank is produced by the impeller within a draft tube.  The leading edge of the blades of the impeller are inclined with respect to radial lines extending from the axis of rotation of the impeller beyond the angle of repose of the fibers on the leading edge.  Also, the coefficient of friction of the portion of the impeller, extending from the leading edge toward the trailing edge thereof, to which the fibers adhere is reduced by providing the surface thereof with a low coefficient of friction material.

Each spring contact includes opposed, deflectable contacting portions for engag-ing the conductive strips disposed on opposite sides of the insertable edge of the printed circuit board. The opposed contacting portions define an opening through which the edge of the printed circuit board may be inserted in the cavity of the connector hous-ing with low or zero insertion force. Subsequently, the printed circuit board is pivoted or rotated through an angle into a final contacting position, in which position the conductor strips on the printed circuit board engage and deflect the contacting por-tions of the spring contacts with a relatively high contact force. The connector housing includes first and second integrally formed stops or limit surfaces respectively associated with each of the opposed con-tacting portions of each spring contact that control or limit the deflection of the contacting portions and the resultant stress imparted to the spring contacts.

Inner and outer charge carrier regions having a high density of first charge carriers is formed in the substrate to define a channel region therebetween.  The inner carrier region is adjacent the isolation region so that the channel region extends in a closed loop from said isolation region, around the inner carrier region and back to the isolation region, with the outer carrier region surrounding the isolation and channel regions.  The chan-nel region has a low density of second charge carriers, having opposite charge than the first charge carriers, and a gate structure including a conductive band and an insu-lating layer is formed over the channel region.  In one alternate embodiment, additional isolation regions may be provided with these regions interrupting the channel re-gion.  In another alternate embodiment, the isolation region extends across the cell element and divides the inner and outer carrier regions and the channel region each into two sections.  On one side of the isolation region, the inner and outer carrier regions have first charge carriers with the associated channel having second charge carriers; on the other side of the isolation re-gion, the inner and outer carrier regions have second charge carriers with the associated channel region having first charge carriers
