    • A dynamic wheel bearing test system employs a motor and fly wheel interconnected through a drive shaft and clutch or speed control with a wheel portion mounted upon a fixed axle with test bearings interposed therebetween. The drive shaft is received by and rotates within a load reaction block to which are connected hydraulic actuators operating in three orthogonal planes to impart loads to the bearings. A first set of actuators provides radial loads to the bearings, a second provides side loading of the bearings, while a third set of actuators simulates a drag upon the aircraft employing the wheel and bearings under test.

    • A valve seat (28) having a generally saddle-shaped, eccentric surface (52); a groove (50) of constant depth and width formed in the eccentric surface, having sidewalls (70) perpendicular to the eccentric surface and a base (72) parallel to the eccentric surface; and a flexible O-ring (54) retained by friction within the groove. The groove sidewalls and base have a surface finish in the range of about 32 to 125, which provides sufficient smoothness to retain the O-ring in the required non-planar shape.The valve seat groove (50) can be produced according to the disclosed method, which is preferably implemented in a numerically controlled four-axis horizontal milling tool system. The valve seat part (100) is mounted in a fixture (102) on a rotary table (104) such that the part axis (56) is aligned with the longitudinal axis (Z) of the tool (106). Once the initial penetration position and depth of the tool (106) is established on the eccentric surface (52a) of the part (100), the only required machine movements are table rotation (104) and tool vertical axis movement (Y).

    • This invention provides novel aqueous fluid compositions which comprise a synergistic mixture of two classes of water dispersible or soluble polymers, i.e. (1) synthetic polymeric viscosifier and (2) polycationic organic polymer. These compositions are uniquely adapted for use in enhanced oil recovery. Addition of the polycationic organic polymer reduces the solution viscosity, increases the injectivity of the aqueous solution into low permeability formations. This reaction also reduces the shear degradation of the polymers during pumping, injection through the perforations, and during the period of relatively rapid fluid movement as the solution moves through an earthen or subterranean formation in the important zone within about a ten foot radius around the well bore. Once in an earthen formation, the polycationic organic polymer is rapidly adsorbed from the solution resulting in an increase in solution viscosity and improving the mobility ratio and also resulting in enhanced and/or increased oil recovery.
    • 本发明提供新的含水流体组合物,其包含两类水分散性或可溶性聚合物的协同混合物,即(1)合成聚合物增粘剂和(2)聚阳离子有机聚合物。 这些组合物独特地适用于增强采油。 加入聚阳离子有机聚合物降低溶液粘度,增加水溶液注入低渗透性地层。 该反应还降低了聚合物在泵送过程中的穿透过程中的剪切降解,以及在相对快速的流体运动期间,当溶液通过围绕井的大约十英尺半径内的重要区域中的土层或地下岩层移动时, 孔。 一旦形成土层,聚阳离子有机聚合物从溶液中快速吸附,导致溶液粘度增加并提高迁移率,并且还导致提高和/或提高的油回收率。

    • A sensor for capturing light at the ultraviolet (UV) or the deep UV wavelength includes a multi-layer anti-reflective coating (ARC). In a two-layer ARC, the first layer is formed on either the substrate or the circuitry layer, and the second layer is formed on the first layer and receives the light as an incident light beam. Notably, the first layer is at least twice as thick as the second layer, thereby minimizing an electrical field at a substrate surface due to charge trapping in the ARC. In a four-layer ARC, the third layer is formed on the second layer and the fourth layer is formed on the third layer. The first and third layers may be formed from the same material, and the second and fourth layers may be formed from materials having same/similar indexes of refraction. In this case, the first layer is at least twice as thick as any of the second, third, or fourth layers.
    • 用于在紫外(UV)或深紫外波长下捕获光的传感器包括多层抗反射涂层(ARC)。 在两层ARC中,第一层形成在衬底或电路层上,第二层形成在第一层上并接收作为入射光束的光。 值得注意的是,第一层的厚度至少是第二层的两倍,从而由于ARC中的电荷捕获而使衬底表面的电场最小化。 在四层ARC中,第三层形成在第二层上,第四层形成在第三层上。 第一层和第三层可以由相同的材料形成,并且第二层和第四层可以由具有相同/相似折射率的材料形成。 在这种情况下,第一层的厚度至少是第二层,第三层或第四层中的任一层的两倍。
