20080290651 | MULTIPLE FOLD PRODUCT AND METHOD OF MAKING THE SAME - A multiple fold product includes a relatively rigid substrate, such as paperboard, which has upper and lower surfaces. Slots are selectively cut into the substrate at the desired fold locations. The slots divide the substrate into an array of interconnected rectangular sections that are arranged in horizontal rows and vertical columns and which are interconnected by tabs. A first transparent, flexible sheet of material is mounted on the upper surface of the substrate. The first sheet of material has selected intelligence reverse printed on its lower surface such that the printed material is interposed between the substrate and the first sheet of material when the first sheet of transparent material is mounted on the substrate. A second transparent, flexible sheet of material is mounted on the lower surface of the substrate. The second sheet of material has selected intelligence reverse printed on its upper surface such that the printed material is interposed between the substrate and the second sheet of material when the second sheet of material is mounted on the substrate. Layers of opaque material interposed between the sheets of material and the substrate. | 11-27-2008 |
20090029156 | SUBSTRATE HAVING POLARIZED ADHESIVE - A surface cover having a polarized adhesive material bonded or operably connected to at least a portion of a substrate. The polarized adhesive material may be a hot melt adhesive material. The substrate may have little or no electret capabilities. The electrostatic charge of the polarized adhesive material may allow the surface cover to be removed from a mounting surface for positional adjustment during the application of the surface cover to the mounting surface. Once at its desired location, and/or aligned with the patterns, characters, or images on an adjacent surface cover, the polarized adhesive material may be activated. The adhesive force provided by the activated polarized adhesive material may provide a sufficient force for adhering surface cover along the mounting surface, thereby malting the dissipation or loss of electrostatic charge inconsequential to the ability of the surface cover to remain at its desired position along the mounting surface. | 01-29-2009 |

20100199948 | Concurrent Injection Of Liquid And Gaseous Fuels In An Engine - Disclosed is a method and corresponding fuel injector for injecting gaseous and liquid fuel into an engine. The method comprises delivering a liquid fuel to a fuel injector, delivering a pressurized gaseous fuel to the fuel injector, entraining the liquid fuel within the gaseous fuel within a chamber of the fuel injector and injecting the gaseous fuel and atomized liquid fuel into the combustion chamber. The liquid fuel can be passed through and dispensed from a needle into a chamber in the injector nozzle where it is entrained in the gaseous fuel during an injection event. The liquid/gas mass ratio is controlled by the needle movement, hydraulic resistances or electronic valves so that the majority of the liquid is injected during the first part of the gas injection. The injector can be used for late cycle direct injection of natural gas, or any number of gaseous fuel blends combined with many liquid fuels such as diesel, biodiesel and DME. | 08-12-2010 |
