Abstract: A THERMAL TRANSFER COLOR PRINTER  FOR PRINTING ON SHEETS OF PAPER            ABSTRACT OF THE DISCLOSURE A thermal transfer color printer is disclosed for printing color images on individual sheets of paper. One sheet of paper at a time is removed from a stack of paper stored in a cassette and this sheet is transported by a reversible platen roller in a first or forward direction at a first predetermined rate. While the sheet of paper is gripped between the reversible platen roller and one or more pinch rollers, slack is removed by a slack removing device. A multicolored ink ribbon with successively arranged color segments also is transported in the first direction at the same predetermined rate. A thermal printhead presses against the reversible platen roller to press the ink ribbon and sheet of paper together as they move in the first direction. Energization of the thermal elements on the thermal printhead by color component signals corresponding to the current color of the ink ribbon causes the particular current color to be thermally and selectively transferred to the sheet of paper. The thermal printhead then disengages the platen roller and the sheet of paper is transported in a set distance in a second direction opposite the first direction, and at a second predetermined rate, in order to repeat the process of thermally transferring other colors to the sheet of paper. During the back and forth movement of the sheet of paper, the reversible platen roller and the pinch rollers continuously grip the sheet of paper in order to precisely control the position of the sheet of paper to thereby avoid distortion. A complete color image is formed on the sheet of paper by superimposing the multiple colors of the ink ribbon as the sheet of paper and the different colors of the ink ribbon repeatedly move past the selectively energized thermal elements of the thermal printhead.

Abstract: ABSTRACT           A transportable trailing wide-swath wheel-supported implement such as a rock windrower is conveniently able to convert from wide-swath working mode to a transversely narrower folded mode for convenient transport of the implement.  The folding elements are a drawbar and the wheel legs, each of these being pivotally attached to the implement frame about a substantially vertical pivotal axis.  In working mode, the wheel legs and drawbar are extended at a relatively large acute angle or right angle to the frame whereas in transport mode they pivotally retract to assume relatively small acute angles to the frame.  The wheel legs may be locked in either extended or retracted position.  Between the drawbar and the frame is preferably pivotally connected a hydraulic piston-cylinder arrangement, permitting the angle of the drawbar to the frame to be adjusted and controlled.  If the implement is of the type having a working element in ground engaging contact, means such as an additional hydraulic piston-cylinder arrangement are preferably provided to enable the working implement to be pressed against the ground and to remove the weight from the implement-supporting wheels, the wheel legs rising above the ground permitting the wheels to clear the ground thereby facilitating their repositioning about the pivotal axis of connection to the frame.

Abstract: ABSTRACT OF THE DISCLOSURE         A tracking servo signal is generated for use in an optical disc pick-up system, being particularly advantageous for use when the depth of the pits is greater or less than one-fourth the wavelength of the light beam used to read the disc, in which case diffraction patterns formed by reflected light beams are not symmetric on a photo-detector and typically result in DC-shifted tracking error signals. A first tracking error signal is generated from selected output signals of a number of light-receiving areas of the photo-detector and a second tracking error signal is generated by combining output signals from these light-receiving areas in a pattern different than that used in generating the first tracking error signal.  These two tracking error signals are combined so that the resultant signal forms a tracking servo signal that has substantially no DC component.

Abstract: A FLOW CHECK MECHANISM Abstract of the Disclosure A flow check mechanism is disclosed which is useful in a female coupler for preventing closure of a male coupler coupled thereto should a vacuum occur in the female coupler.  The flow check mechanism includes a housing having a cylindrical bore formed therein with an inlet port at one end and an outlet port at an opposite end.  Formed within the cylindrical bore, between the inlet and outlet ports, is a pair of recesses.  A resilient ball is positioned in the cylindrical bore between the pair of recesses and has an outside diameter slightly larger than the inside diameter of cylindrical bore but less than the diameter of either of the recesses.  The flow check mechanism further includes first and second springs positioned in the cylindrical bore between the inlet port and the ball and between the ball and the outlet port, respectively.  The springs retain the ball in contact with the inner periphery of the cylindrical bore when the fluid pressure forces acting on opposite sides of the ball are approximately equal.  When the fluid pressure impinging on a given side of the resilient ball exceeds the fluid and spring forces on the opposite side of the ball, the ball will move into alignment with the respective recess and relieve the fluid pressure forces acting thereon.  Since springs of different spring forces may be used, it is possible for the resilient ball to permit fluid flow in one direction at a low pressure and to permit fluid flow in the opposite direction at a higher pressure.

Abstract: SINGLE NEEDLE BLOOD FRACTIONATION SYSTEM HAVING ADJUSTABLE RECIRCULATION THROUGH FILTER     Abstract of the Disclosure A single needle batch-type blood fractionation system for separating plasma from whole blood includes a disposable flow sys-tem having a single-lumen phlebotomy needle and associated donor conduit, a flow-through plasma separation filter, and an in-process fluid reservoir.  During an initial draw cycle whole blood is pumped through the filter to the in-process reservoir by a peristaltic-type inlet pump operating at a predetermined draw rate.  When a predetermined volume of filtered plasma-deficient blood has been collected in the reservoir, as sensed by the weight of the reservoir the system reverts to a return cycle wherein a portion of the plasma deficient blood in the reservoir is pumped back to the donor con-duit by a peristaltic-type return pump operating at a predetermined return rate higher than the draw rate of the inlet pump.  Depending on the relative operating speeds of the inlet and return pumps, an operator-controllable portion of the plasma-deficient blood from the in-process reservoir is returned to the donor through the phle-botomy needle, and the remaining portion is recirculated through the filter.  The partial recirculation of plasma-deficient blood through the filter during the return mode reduces the processing time of the system, provides for improved accommodation of whole blood of unusually high or low hematocrit, and enables the use of a smaller and less expensive filter.

Abstract: ABSTRACT    A nozzle assembly comprising a tubular sleeve, a nozzle and a nozzle body.  The nozzle and nozzle body are held in an assembled relation with their bores  aligned by the  tubular  sleeve which encircles them.   The sleeve provides a seal between the nozzle assembly and the body into which the nozzle assembly is mounted, and  also provides  a  seal between  the nozzle and nozzle body.          During use, when under working pressure, the tubular sleeve tends to  flow  and  move both  downstream and  radially,  forming  seals between the nozzle assembly and the body into which it is mounted; and  between  the  nozzle  and  nozzle  body,  which  seals  tend  to increase in effectiveness at the working pressure increases.   In another  form,  the  set  screw  has  a  chamfer  which  engages  a corresponding circular corner of said body, preventing downstream flow of the sleeve therebetween.
