Abstract: A multicolor organic light emitting device employs vertically stacked layers of double heterostructure devices which are fabricated from organic compounds. The vertical stacked structure is formed on a glass base having a transparent coating of ITO or similar metal to provide a substrate. Deposited on the substrate is the vertical stacked arrangement of three double heterostructure devices, each fabricated from a suitable organic material. Stacking is implemented such that the double heterostructure with the longest wavelength is on the top of the stack. This constitutes the device emitting red light on the top with the device having the shortest wavelength, namely, the device emitting blue light, on the bottom of the stack. Located between the red and blue device structures is the green device structure.

Abstract: There is disclosed a portable rack made entirely of metal which is uniquely suitable for use in storage and transporting of reels of wire or cable. The rack is designed to accommodate a desired number of cable reels in such a way that fully loaded reels may be stacked atop each other for transporting or storage of such reels, in such a way that the geometric features of the racks accommodate the geometric features of the reels to form a stable stack. The preferred embodiment of the reel rack is sufficiently small in size and weight that it can be manually moved or handled when not in use, yet sufficiently strong to withstand a vertical load of eight tons or more when in use.

Abstract: A self-adhesive wall board joint tape has a paper base layer with a mud or plaster receptive surface, the other surface has a pressure sensitive adhesive. A transfer liner is applied with a release surface against the adhesive surface of the paper base layer, and is coated on the opposite side with a low-tack releasable adhesive. When wound into rolls the transfer liner low-tack adhesive engages the untreated surface of an underlying base layer. The pull strength of the low-tack adhesive is selected to be greater than the pull strength of the high-tack adhesive on the release surface of the transfer liner. When unwound from the roll the transfer liner is adhered to the non-adhesive paper base layer, and the adhesive high-tack surface of the paper base layer is presented for immediate adhesion, without the need to remove a backing.

Abstract: An insulating unit has a pair of glass sheets about an edge assembly to provide a compartment between the sheets. The edge assembly has a U-shaped spacer made of metal, metal coated plastic, gas and moisture impervious polymer, or gas and moisture impervious film coated polymer. The outer legs of the spacer and the glass provide a long diffusion path to limit the diffusion of argon gas out of the compartment. The edge assembly has materials selected and sized to provide edge assembly having an RES-value of at least 75. A spacer for use in insulating units includes a plastic core having a gas impervious film e.g. a metal film or a halogenated polymer film. Also taught herein are techniques for making the unit and spacer.

Abstract: A quick wire coupling and release primarily adapted to provide a quick, safe and economical coupling of river barges into a tow by use of wire rope with the coupling and release also being capable of use in other applications. The quick wire coupling and release includes a wire latch and a rolling cam take-up assembly with one end of a wire rope having a socket and pin thereon which is coupled to the rolling cam take-up assembly and looped around the opposite timber head or fitting on an adjacent barge and brought back through the wire latch to remove slack from the wire rope with the cam assembly providing a final tension to the wire rope thereby securely retaining adjacent barges in abutting engagement to form a single unit.

Abstract: An improved marking device for use with an animal harness to provide a means for identifying mated animals by color code. A replaceable marking device such as a marker block of colored crayon is secured to the animal harness by a snap fitted retaining means thus providing for safe, quick and easy replacement of spent markers.

Abstract: Method and apparatus for the conversion to and from digital form of a PAL color television signal is described in which the digital signals represent the error between a particular sampled value of the signal and a predicted value for that particular sample, the predicted value being based on a previously occurring sampled value together with the difference between two similarly spaced sampled values occurring in the preceding line, the spacing of the two pairs of sampled values in the two lines being such that the phase change of the sub-carrier, if unmodulated, is the same in both cases. A simple switch delay system is described for effecting the selection of the sampling instants in the preceding line.

Abstract: A vehicle seat assembly includes an actuator controlled by a three-position spool valve which is connected by an adjustable two-link linkage to the seat. The valve is directly responsive to the geometry of the linkage to urge the seat, regardless of the load on the seat, to a ride position established by the linkage.

Abstract: A seat backrest having a contourable upholstered portion supported by a rigid frame includes means to impart a curvature to the upholstered portion to produce a desired supporting contour in the lumbar area of the seat's occupant. The contour-producing means includes a lumbar pad, a resilient member connecting the lumbar pad to the frame, and means operable from the side of the backrest for moving and holding the connecting member in a plurality of positions.

Abstract: A seat assembly has a seat frame tiltably supporting a back frame for movement about an axis parallel to the intersection of planes parallel to the seat and back frames, and has an adjusting mechanism for controlling the degree of tilt from a position to the side of and exterior to the seat frame. The adjusting mechanism includes a tilt adjustment slide movable in a channel provided in the side of the seat frame and having a groove therein oblique to the direction of movement of the slide. The slot engages a stud mounted in the back frame and movement of the slide towards and away from the axis of tilt causes the stud to move relative to the channel resulting in movement of the back frame relative to the seat frame.

Abstract: A seat backrest having a contourable upholstered portion supported by a rigid frame includes means to impart a curvature to the upholstered portion to produce a desired supporting contour in the lumbar area of the seat's occupant. The contour-producing means includes a lumbar pad, a flexible member connecting the lumbar pad to the frame, and means operable from the side of the backrest for moving and holding the connecting member in a plurality of positions.
