  • Patent number: 12091255
    Abstract: A conveyor system includes a conveyor belt having a plurality of article-diverting conveyor belt rollers. An underlying drive roller assembly includes a plurality of pivotable rollers carriers, each having a freely rotatable drive roller that contacts the conveyor belt rollers from below. An actuator engages an orientation device to pivot the carriers and change the orientation of the drive rollers. The drive rollers may also move into and out of engagement with the conveyor belt rollers as their orientation changes. The orientation device is sandwiched between three-dimensional support plates to adjust the orientation of the drive rollers relative to the belt rollers. A top support plate includes corrugated vertical walls forming wearstrip holders. The orientation device may raise or lower the drive rollers during pivoting of the roller carriers. The drive roller assembly may be a modular assembly that can be customized for varying sizes, shapes and configurations.

  • Publication number: 20240279391
    Abstract: Mixtures are disclosed containing a plurality of charged pigment particles and one or more charge control agents. At least one of the charge control agents has a chemical structure that includes a cationic head group, such as an ammonium cation or an iminium compound, and a non-ionic, polar functional group, other than an acyclic secondary amide group. The mixtures are useful as dispersions for forming electrophoretic media that may be incorporated into electrophoretic displays. Alternatively, the dispersions may be useful for forming electrophotographic toners and dispersions for other printing applications.

  • Patent number: 11656522
    Abstract: A temperature regulation system includes a laminate material that has a first light transmissive electrode layer, a rear electrode layer, and a bistable electrophoretic medium disposed between the first and second electrode layer. The electrophoretic medium includes two types of particles that have different charges and color. The amount of incident radiation (visible light, infrared, etc.) that is absorbed by the laminate can be modified by providing a voltage between the electrode layers.

  • Publication number: 20220413323
    Abstract: An electrophoretic medium includes a fluid, a plurality of light scattering charged particles having a first polarity, and a first, second, and third set of particles, each set having a color different from each other set. The first and second particles may have a second polarity opposite to the first polarity, and the mobility of the third set of particles is less than half of the mobility of the light scattering particles, the first set of charged particles, and the second set of charged particles.

  • Publication number: 20220211657
    Abstract: Aspects of the technology described herein are directed to a method of treating gastrointestinal cancer in a subject. This method involves selecting a subject, where the subject (i) has been diagnosed with a gastrointestinal cancer and (ii) has (a) a pathogenic mutation in one or more homologous recombination-DNA damage repair (HR-DDR) pathway genes and/or (b) a family history suggestive of a breast or ovarian cancer syndrome; and administering to the subject an effective amount of a Poly(ADP ribose) polymerase (PARP) inhibitor, in combination with oxaliplatin and an antimetabolite. Methods of treating a gastrointestinal tumor in a subject and of increasing sensitivity of gastrointestinal tumor cells to oxaliplatin are also disclosed.
