  • Patent number: 7748148
    Abstract: A backlit display sign includes a rear sign enclosure element at the back of the sign with a forwardly facing wide mouth opening. Extending across the mouth opening is a front sign element or cover formed from an optically transmissive light guide which extends laterally across the mouth opening of the display. Light diffusing (scattering) reflective layers on the front and rear surfaces of the guide or within the guide itself make the guide a light propagation sustaining channel that serves to funnel light rays laterally and forwardly within itself to an image-producing opening where the light is allowed to be emitted for producing the image of a symbol, letter, number or other indicia that is visible on the front of the display. A light cavity between the front cover and the rear sign enclosure element contains at least one illuminating device, e.g. a light emitting diode (LED), to provide visible illumination that is transmitted from within the light cavity through the guide to the front of the sign.

  • Patent number: 7726554
    Abstract: A multiple punch and multiple die assembly has a workpiece protector which is a punch lifter that is operatively associated with each punch for supporting each of the punches in an inactive position as an active punch is moved by the ram to the active, i.e. operating position to thereby eliminate scoring or marking of the sheet material or other workpiece that is being punched. To eliminate the need for hand tools and hand assembly or disassembly, a manually moveable retainer on the punch assembly is provided that can be moved by hand between a punch-releasing and punch-retaining position for holding the punches within the multi-punch assembly during operation. To prevent stress fractures that formerly occurred in die carriers, support of each die is distributed between two different die components thereby reducing impact stress on the carrier as the ram drives the punch through the workpiece.

  • Patent number: 7553326
    Abstract: To prevent intimal hyperplasia within a dialysis graft, a flexible tube comprising the dialysis graft is coated interiorly before placement with an anticarcinogen or mitosis-inhibiting agent for preventing cell division. The graft can also be irradiated with light energy by directing light into the lumen of the tube that has been grafted in place, thereby preventing or reducing dialysis graft intimal hyperplasia and reducing inflammation. The light source can be a light emitting diode (LED) or a chemical light source, i.e., a chemiluminescent substance for producing cool light energy within the graft to prevent or reduce the symptoms of GIH. When phototherapy is used, the body is exposed to light radiation at the site of the graft in sufficient amount to prevent undesired cell proliferation within the vessels, the graft, or surrounding tissue where the invention is used without detectable damage to body tissue.
