20080264796 | LATERAL WIRE APPARATUS AND METHOD FOR MONITORING OF ELECTROPHORETIC INK PARTICLE MOTION - A lateral wire apparatus allows direct lateral viewing of particles of electrophoretic ink (e.g., liquid emulsion aggregation particle (LEAP) ink) that are undergoing electrophoretic migration. Electrophoretic ink movement is commonly monitored by placing the ink through the top electrode, but as the toner particles migrate back and forth between the two electrodes, the viewer can not see what lies beneath the top electrode. This may hide commonly known failure modes, such as particle agglomeration, swishing of particles due to hydrodynamic effects. The lateral wire apparatus includes two narrow gauge wires glued to a glass substrate and held apart at a fixed distance to help maintain a uniform electric field across the gap. A plastic block with pegs that situated at a fixed distance and threaded screws is used to make the lateral wire apparatus with precise wire spacing that may be reproducibly made in less than five minutes using inexpensive and readily available materials. | 10-30-2008 |

20110209955 | SHOCK STRUT WITH PRESSURE RELIEF - A shock strut includes a relief device that reduces the internal pressure within a sealed chamber of the shock strut when a load condition that exceeds a maximum operating load condition is encountered. The reduced pressure permits a telescopically moving piston of the shock strut to be received into a corresponding cylinder to an amount that increases the structural capability of the shock strut, especially with respect to applied side loads that generate bending and shearing stresses in the shock strut. In one embodiment, the reduced pressure permits the piston to “bottom out” relative to the cylinder, which is a condition not otherwise achievable without the relief device. This additional stroke achievable by the piston reduces or eliminates the need to reinforce and thus add weight to the shock strut because of higher load condition design requirements. | 09-01-2011 |
