| 20100110550 | Variable Transmission Composite Interference Filter - Now, according to the present invention, interference filters are provided that incorporate two band pass interference filters into a single composite interference filter. The two filters each have at least one band pass curve that is centered at the same wavelength for light that is incident at a given angle to the filter surface. The band pass curve shifts of the filter components, however, are dissimilar, which results in a decrease of transmitted light as the angle of incidence diverges from the given angle. | 05-06-2010 |

| 20100272381 | Bearing assembly having a dual stage seal - A bearing assembly is presented having a novel lubricant sealing design that, in one embodiment, combines the sealing advantages of both a labyrinth-like seal in combination with a contact seal. The improved seal includes a non-rotating seal case working in closely spaced cooperation with a rotor to form a channel. The rotor is attached and turns with the shaft, inducing flow in the channel. Lubricant leakage is impeded by the tortuous fluid path formed by the convoluted channel of the labyrinth-like seal and the fluid shear forces developed by the turning shaft. Any lubricant leakage is further impeded by a resilient seal contacting the surface of the rotor and constricting the channel. | 10-28-2010 |
| 20100322544 | Bearing assembly having a dust seal arrangement with contacting and non-contacting dust seals - A bearing assembly is presented having a novel lubricant sealing design that, in one embodiment, combines the advantages of contacting and non-contacting dust seals to balance energy efficiency while still providing an effective method for contaminant exclusion. The contacting and non-contacting dust seals further arranged to maximize the service life of the dust seals and prolong the maintenance intervals required on the bearing assembly. | 12-23-2010 |
| 20110064347 | Roller bearing backing ring - A novel two-piece backing ring assembly for a railcar axle is presented. The backing ring assembly has an annular body affixed to the fillet of the journal and a locking ring for further affixing the annular body into position on the journal. The locking ring has an inboard end affixed to the dust guard of the shaft and an outboard end for engaging a slot in the annular body. The locking ring assembly may be retrofitted to older generation railcar axles to increase the structural rigidity of the bearing assembly and minimize fretting wear caused by railcar axle deflection. | 03-17-2011 |
| 20110123142 | Railway car roller bearing - A bearing assembly is provided having a roller bearing a cone forming an inner race fitted around the journal portion of an axle. A cup forms an outer raceway that combines with the inner raceway to receive roller elements. A backing ring is centered to the shaft fillet. Tapered roller elements are located between and contact the inner and outer raceways. A cage is comprised of an inner ring, and outer ring, and a plurality of pocket bars extend between the inner and outer rings. The pocket bars of the cage include a protrusion that is received in a groove in the cone. | 05-26-2011 |
| 20110216993 | Railway car bearing seal - A bearing assembly is provided having a roller bearing with an inner raceway fitted around the journal portion of an axle. An outer raceway combines with the inner raceway to receive roller elements. An improved lubricant seal arrangement is provided between the wear ring and the supporting outer raceway comprising a stator element, a rotor element and a flinger element. | 09-08-2011 |

| 20110168144 | Method and apparatus for operating standard gasoline-driven engines with a readily-available non-volatile fuel, thereby obviating the use of gasoline - The conventional spark plug (or plugs) of a spark-fired gasoline engine are removed and replaced with a high-power spark plug (or plugs) capable of delivering very high power (e.g., one megawatt) over a relatively-narrow time interval (e.g., 20 nanoseconds). Next, the gasoline is replaced with a readily-available non-volatile fuel (e.g., JP-8). The gasoline—and its transportation, storage, handling and/or use—is eliminated altogether, thereby removing a strategic and tactical threat from enemy and terrorist forces who otherwise would be targeting the gasoline tanks or transports. Additionally, or alternatively, the fuel in the line (or the fuel injector) may be heated to start a cold engine or under cold ambient temperatures. The invention is also applicable to consumer products (e.g., lawnmowers) where the extra expense of occasional use is a tradeoff for safety and convenience. | 07-14-2011 |
