  • Patent number: 11990487
    Abstract: A reflective member having transflective and substantially opaque regions is disclosed. The transflective region may serve as a sensor opening region. When viewing the member from a first direction, the difference between a total light reflectance of the member at the substantially opaque region and at the sensor opening region is less than five percent. Additionally, when viewing the member from the first direction, the difference between a color reflectance of the member at the substantially opaque region and at the sensor opening region is less than 5 delta C* units. A sensor disposed in a second direction of the sensor opening region of the member is operable to receive light through the member at the sensor opening region. The second direction is opposite the first direction.

  • Patent number: 5724715
    Abstract: A composite flange providing the low cost and bonding capability of molded flanges with the torque capacity near that of metal flanges. Multiple layers of braided fiberglass enveloping a fiberglass ring are placed into a mold of the desired shape. After the mold is closed, liquid resin is injected and the flange is cured to the desired state. After demolding, the flange is machined as necessary for installation onto the drive shaft.

  • Patent number: 3958064
    Abstract: Magnetic recording tape having a backing of biaxially oriented polyethylene terephthalate film containing small amounts of at least two types of structurally dissimilar minute polymeric particles. One type of particle is selected from the class consisting of polypropylene, styrene-acrylonitrile polymer, nylon and incompatible polyesters and the other from the class consisting of polymers of lower olefins. The tape, which has a microscopically irregular, scratch-resistant back free from large protruding particles, is especially adapted for use in instruments and computers, where the resultant dropout incidence is extraordinarily low. A further refinement employs as a backing a two-layer coextruded film, the back layer containing the polymeric particles and the face layer containing no particulate matter and hence being extremely smooth. When the smooth surface of the face layer of such a thin two-layer film is metallized, a mirror-like appearance results; the film can, however, still be handled in roll form.
