    • An electrical homopolar capacitor generator includes a set of stacked dielectric plates and conductive plates arranged in a magnetic field, with at least one of the dielectric plates is rotated relative to the remainder of the plates to generate an electrical output charge between the conductive plates. One version of the generator employs flat circular disks with an inner dielectric disk rotated relative to the others. The inner disk is placed between a pair of electrically conductive plates, which in turn are placed between a pair of first and second dielectric plates which are in a fixed relationship to the conductive plates. A second embodiment utilizes concentric cylinders in a similar arrangement to the stacked circular disk embodiment, with relative rotation of an inner dielectric being effected along a common axis for all of the cylindrical plates.
    • 电气单极电容器发生器包括一组堆叠的电介质板和布置在磁场中的导电板,其中至少一个电介质板相对于其余的板旋转以在导电板之间产生电输出电荷。 发电机的一个版本采用扁平圆盘,其中内介质盘相对于其它盘旋转。 内盘被放置在一对导电板之间,导电板又位于与导电板成固定关系的一对第一和第二电介质板之间。 第二实施例利用与堆叠的圆盘实施例类似的布置的同心圆筒,内部电介质的相对旋转沿着用于所有圆柱形板的共同轴线实现。

    • Molybdenum is selectively extracted from an aqueous solution containing various other metal values, e.g. copper, arsenic, iron, bismuth, antimony, tin, and lead in addition to molybdenum. The molybdenum-bearing solution is adjusted to a pH of about 2.0 or less, and, then, intimately contacted with an organic extracting solution containing an alpha-hydroxy oxime. The loaded organic phase, containing extracted molybdenum values, is separated from the aqueous raffinate, and the molybdenum values contained in the organic phase are stripped therefrom using an aqueous stripping solution containing ammonium hydroxide. The efficiency with which the molybdenum is stripped from the loaded organic solution is poor unless nonylphenol is present in the organic solution as it is being stripped. The nonylphenol can be added to the system anytime prior to the ammonium hydroxide stripping step, e.g. it can be added to the organic solution before the extraction step, or it can be added to the aqueous-organic mixture during the extraction step (in which case it reports to the organic phase), or it can be added to the organic solution just prior to the stripping step.
    • 从含有各种其它金属值的水溶液中选择性提取钼,例如。 铜,砷,铁,铋,锑,锡和铅除了钼。 将含钼溶液调节至约2.0或更低的pH,然后与含有α-羟基肟的有机萃取溶液紧密接触。 将含有提取的钼值的负载的有机相从残液萃取液中分离出来,使用含有氢氧化铵的水性剥离液从有机相中除去含钼值。 除非在被除去的有机溶液中存在壬基酚,否则从负载的有机溶液中除去钼的效率很差。 可以在氢氧化铵汽提步骤之前的任何时间将壬基苯酚加入到体系中,例如。 可以在提取步骤之前将其加入到有机溶液中,或者在提取步骤中可以将其加入到含水 - 有机混合物中(在这种情况下它报告到有机相),或者可以仅添加到有机溶液中 在剥离步骤之前。

    • A telephoto lens sighting apparatus. A mount couples to a hot shoe of a camera and a first sight couples to the mount. The first sight has a first gap that corresponds with a viewing aperture of a telephoto lens coupled to the camera. A second sight may be movably coupled to the camera through a sliding track and may thereby move with respect to the first sight. The second sight has a second gap, and the first gap and second gap when aligned correspond with a viewing aperture of a telephoto lens coupled to the camera. A first receiver may couple to the camera to selectively receive the first sight and a second receiver may couple to the camera to selectively receive the second sight. The first sight and second sight may each pivot to a plurality of positions and their heights may be adjusted.
    • 远摄镜头瞄准装置。 一个安装座搭配相机的热靴,一见钟情的搭配。 第一视野具有与耦合到照相机的远摄镜头的观察孔对应的第一间隙。 第二视野可以通过滑动轨迹可移动地耦合到相机,并且因此可以相对于第一视线移动。 第二视野具有第二间隙,并且对齐时的第一间隙和第二间隙对应于耦合到照相机的远摄镜头的观察孔。 第一接收器可以耦合到相机以选择性地接收第一视线,并且第二接收器可以耦合到相机以选择性地接收第二视线。 第一视线和第二视线可以各自枢转到多个位置,并且可以调整其高度。
