    • A fluorometer for measuring a particular fluorescence emanating from a specimen and operating in accordance with the following method. Producing a burst of concentrated light energy and directing the concentrated light energy toward the specimen to produce a fluorescence from the specimen including the particular fluorescence. Preferably producing an image of the fluorescence. Detecting the fluorescence and producing a signal in accordance with the fluorescence. Controlling the passage of the image of the fluorescence for detecting within a particular time period so as to optimize the detection of the particular fluorescence. Timing the operation to sequence the detection of the fluorescence within the particular time period after the production of the burst of concentrated light energy. Scanning the fluorescence from the specimen for forming signals representative of the fluorescence from the specimen. Analyzing the signals to enhance the portion of the signal representing the particular fluorescence relative to the portion of the signal.
    • 一种荧光计,用于测量从样品发出的特定荧光并根据以下方法进行操作。 产生集中的光能的突发,并将集中的光能引导到样品以从包括特定荧光的样品产生荧光。 优选地产生荧光图像。 根据荧光检测荧光并产生信号。 控制在特定时间段内用于检测的荧光图像的通过,以便优化特定荧光的检测。 计算在产生聚集的光能的突发之后的特定时间段内对荧光的检测进行排序的操作。 扫描来自样品的荧光,以形成代表来自样品荧光的信号。 分析信号以增强表示相对于信号部分的特定荧光的信号部分。

    • Apparatus is provided to detect a discontinuity indicative of a hole in the bore wall of an axially extending tubular member. It comprises:(a) a carrier to be traveled axially lengthwise in the bore of the tubular member,(b) an acoustical wave transmitter located on the carrier to transmit acoustical waves for travel toward the bore wall and for reflection therefrom,(c) an acoustical wave detector at least partially located on the carrier to receive acoustical waves reflected from the bore wall and to detect the presence or absence of such reflected waves, and(d) a control for providing an indication of such discontinuity, and for controlling the transmission to the detector of the reflected acoustical waves, and characterized in that the detector is controllably exposed to reception of a sequential succession of reflected acoustical waves corresponding to a sequential succession of bore wall portions from which the waves are reflected.
    • 提供了用于检测指示轴向延伸的管状构件的孔壁中的孔的不连续性的装置。 它包括:(a)在管状构件的孔中沿纵向轴向行进的载体,(b)位于载体上的声波发射器,用于传送声波以朝向孔壁行进并用于反射;(c) 至少部分地位于载体上以接收从孔壁反射的声波并检测这种反射波的存在或不存在的声波检测器,以及(d)用于提供这种不连续性的指示的控制,并且用于控制 传输到反射声波的检测器,并且其特征在于,检测器被可控地暴露于对应于波形从其反射的连续的孔壁部分的顺序连续的反射声波。
