  • Publication number: 20210324907
    Abstract: An idler roller having a fixed shaft with at least one spherical bearing and a second bearing which may, but need not be, a spherical bearing. In some embodiments, the second bearing is slidably-mounted on a central shaft. A shell is mounted between these bearings. Any changes in dimensions resulting from changes in temperature may them be accommodated by sliding movement of the second bearing, sparing the shell from distortion by bending or buckling. In other exemplary embodiments, the spherical bearing includes a first housing element fixedly-mounted on a central shaft and a complementary first free element disposed against the first housing element. A second bearing element is mounted on the central shaft, and a shell is attached to the first free element and rotatably-mounted to a second bearing element with a biasing element mounted on the central shaft urging a second free element away from the first free element.

  • Publication number: 20210260901
    Abstract: A method of applying a pattern to a nonplanar surface with a radius of curvature. A stamp with a major surface has a relief pattern of pattern elements extending away from a base surface. Each pattern element has a stamping surface with a lateral dimension 0 to 5 microns. An ink applied on the stamping surface includes a functionalizing molecule with a functional group that chemically binds to the nonplanar surface. The stamp is positioned to initiate rolling contact between the nonplanar surface and the major surface of the stamp. The stamping surface of the pattern elements contacts the nonplanar surface to form a self-assembled monolayer of the functionalizing material on the nonplanar surface and impart the arrangement of pattern elements. A relative position of the stamping surface is controlled with respect to the nonplanar surface while the major surface of the stamp contacts the nonplanar surface.

  • Patent number: 11090682
    Abstract: A process for applying a coating material onto a substrate as a non-uniform discontinuous pattern of coating material, the method including the present disclosure describes a method of applying a coating material onto a substrate, including providing a first distribution manifold having a cavity and a multiplicity of first dispensing outlets in fluid communication with the cavity, creating relative motion between a substrate and the dispensing outlets in a first direction; dispensing a first coating material from the dispensing outlets while maintaining the relative motion and translating the multiplicity of dispensing outlets in a second direction non-parallel to the first direction, and varying a rate of dispensing of the first coating material in a predetermined fashion to form a discontinuous pattern of the first coating material on a major surface of the substrate. Useful non-uniformly patterned coated articles can be prepared using the process.

  • Publication number: 20210094272
    Abstract: A method of applying a pattern to a nonplanar surface. A stamp has a major surface with pattern elements having a lateral dimension of greater than 0 and less than about 5 microns. The major surface of the stamp has a functionalizing molecule with a functional group selected to chemically bind to the nonplanar surface. The stamp is positioned to initiate rolling contact with the nonplanar surface, and contacts the nonplanar surface to form a self-assembled monolayer (SAM) of the functionalizing material thereon and impart the arrangement of pattern elements thereto. The major surface of the stamp is translated with respect to the nonplanar surface such that: a contact pressure is controlled at an interface between the stamping surfaces and the nonplanar surface, and a contact force at the interface is allowed to vary while the stamping surfaces and the nonplanar surface are in contact with each other.
