  • STORAGE CONTAINER
    Publication number: 20140367395
    Abstract: The provided containers (100, 200) and methods provide for gravitational alignment of a plurality of stacked articles (120), in which at least two edges (140, 142) of each article align along inner walls (108, 114, 208, 214) of a respective container. The aligning walls of the container are provided with low-friction surfaces to facilitate sliding and alignment of the articles. By aligning the stack of articles along two edges, the articles can be registered relative to not only each other but the container itself, thereby facilitating loading, unloading, and conversion of articles in the stack. Optionally, a compressible layer (147) opposing one or both of the aligning walls conforms and distributes stress along the non-aligning edges, thereby preserving registration of the articles relative to each other when the container is transported.

  • Remote phosphor LED constructions
    Patent number: 8912562
    Abstract: A white light source includes a short wavelength LED and a phosphor layer that emits light at longer visible wavelengths. A dichroic reflector transmits the longer wavelength light, and reflects some LED light onto the phosphor such that as light travels from the LED to the dichroic reflector it does not pass through the phosphor. The LED may emit blue light, and the dichroic reflector may transmit a second portion of the LED light, such that the light source output light includes both the second portion of the LED light and the longer wavelength phosphor light. The LED may be mounted on a flexible substrate having a cavity region and neighboring region, the LED being mounted in the cavity region. A dielectric layer may be thinner in the cavity region than in the neighboring region, or a hole may extend completely through the dielectric layer in the cavity region.

  • Method of eliminating defects while extrusion coating film using speed control of the nip roll
    Patent number: 8911829
    Abstract: It has now been determined that an internal optical defect can be eliminated by controlling the relative speed mismatch between the resilient roll and the casting roll in a film extrusion coating process. In particular, slowing down the surface speed of the resilient roll relative to the casting roll when coating a biaxially orientated film was found to remove the optical defect. Conversely, speeding up the surface speed of the resilient roll relative to the casting roll when coating a uniaxially orientated film was found to remove the optical defect.
