  • Patent number: 6090884
    Abstract: Disclosed herein are starch stabilized polymeric emulsions. Persulfate salts degrade starch to give it suitable characteristics, and then also, essentially simultaneously, initiate polymerization with monomers. This permits a single reaction condition to be used for both the degradation step and the polymerization step, and avoids the need for use of metallic ions such as iron.

  • Patent number: 5952407
    Abstract: A novel thermosettable composition-of-matter is disclosed. One embodiment of the composition-of-matter includes a polymeric thermosettable ingredient having at least three acetoacetoxy-type functional pendant moieties as well as at least three acid-functional pendant moieties. Another embodiment of the composition-of-matter includes at least two polymeric thermosettable ingredients, one of which includes at least three acid-functional pendant moieties and the other of which includes at least three acetoacetoxy-type functional pendant moieties. The novel composition is characterized in that the acid-functional and acetoacetoxy-type functional pendant moieties crosslinkably-react together, when subjected to elevated-temperature conditions for a predetermined period of time, thereby producing a crosslinked polymeric network. The novel thermosettable composition-of-matter can be used "as is" if either of the polymeric thermosettable components is a "fluid" (i.e., is able to flow) at room temperature.

  • Patent number: 5294805
    Abstract: A method and apparatus for analyzing tracking errors in magnetic tape. The apparatus and method allow for distinguishing between those errors in track configuration due to rotational errors (i.e., errors deriving from rotation of the head wheel of a recording and/or reading machine) and errors in track configuration due to other sources of error. An apparatus useful to practice the method holds a magnetic tape in a condition useful for examining the magnetic tape to measure the configuration of recorded tracks on the recording surface of the tape. The apparatus includes means for applying and maintaining a selected tension to the longitudinal and cross-web axes of the tape, a planar measuring surface having X and Y measuring scales allowing for measurement of distances between selected points on the recording surface of the tape, and a microscope or other sensing device for examining the recording surface.

  • Patent number: 5275880
    Abstract: A layered microwave radiation absorber comprises an absorbing layer bound to one side of a conductive layer (such as a metallic plate or foil), and an adhesive layer bound on the other side of the conductive layer. The combination may be applied directly to the surface of any object, but especially to an existing conductive object coated with an nonconductive coating (such as paint) without removing the nonconductive coating from the surface. Several types of absorbing materials may be used, and other layers may be included. The absorber has superior resistance to delamination.

  • Patent number: 5268569
    Abstract: An imaging system employs a photoconductive material capable of bearing a latent photostatic image, a plurality of elongated parallel stripes adjacent the photoconductive material, selective scanning of the stripes to produce charge carriers within the photoconductive material, and time-ordered detection of the current created by the charge carriers with the plurality of elongated parallel stripes. Appropriate addressing of the stripes as they are scanned produces a pixellated representation of the latent image. The system has improved output signal strength and higher resolution than known systems.

  • Patent number: 5268950
    Abstract: A conductive coating on a thin glass strip senses the image signal on a selenium coated photoimaging plate as the plate is scanned with a laser beam. The glass strip is suspended over the surface of the plate with finger-like members. The finger-like members that support the strip are spring loaded downward toward the plate, but are suspended above the plate by a pressurized cushion of air. The strip bends to assume the surface profile of the plate, thus maintaining uniform spacing even though the plate may not be flat and may even have a varying profile along its length.
