    • A strip with an exterior sticky surface is judiciously selected for its ability to entrap dust and other loose debris without interfering with the operation of moving parts contacted thereby. The strip is attached to the sides of a magnetic tape cartridge, with the sticky surface facing outward, in places contacted by rollers and/or belts during the process of handling the cartridge in an automated system. Thus, any loose debris in the rollers or belts is retained by the tacky surface of the strip as the cartridge passes through the rollers and belts of the robotic system. The strips of the invention may be removably adhered to the data cartridge, or may be permanently attached. In a particular embodiment of the invention, the strips may be incorporated into a cleaner cartridge for the periodic maintenance of loading equipment.

    • The present invention is directed to sonic logging while drilling. A transmitter and at least one receiver are mounted on a drill collar for performing sonic investigations of the formation traversed by a borehole. It has been discovered that a drill collar has a natural stop band or notch where acoustic energy propagating in this frequency range is severely attenuated. Thus, to reduce drill collar acoustic coupling, the transmitter is operated within this natural stop band of the drill collar. An imperforate stop band filter is also included between the transmitter and receiver to enhance the natural stop band. The transmitter is mounted transverse to the longitudinal axis of the drill collar, and is preferably mounted within means that reduce drill collar acoustic coupling. The transmitter preferably includes a material whose acoustic response is more favorable along its longitudinal axis relative to its radial axis, thereby directing the acoustic energy into the formation rather than the surrounding drill collar. Received acoustic energy waveforms are electronically processed to reliably detect, in the presence of drilling noise, those acoustic signals which are produced by the transmitter and transmitted through the formation.
    • 本发明涉及在钻探时的声波测井。 发射器和至少一个接收器安装在钻铤上,用于对由钻孔穿过的地层进行声波研究。 已经发现钻铤具有自然的阻挡带或凹口,其中在该频率范围内传播的声能被严重衰减。 因此,为了减少钻铤声耦合,变送器在钻铤的这个自然停止带内操作。 发射器和接收器之间还包括一个无孔挡板滤波器,以增强自然阻挡带。 发射器横向于钻铤的纵向轴线安装,并且优选地安装在减少钻铤声耦合的装置内。 发射器优选地包括其声响应相对于其径向轴线沿其纵向轴线更有利的材料,从而将声能引导到地层而不是周围的钻铤。 接收到的声能波形被电子处理,以便在存在钻井噪声的情况下可靠地检测由发射机产生并通过地层传输的那些声信号。

    • A safety stop is provided for stopping a movable member having at least one set of opposed wheels for gripping a rail. The stop has a track on each of opposite sides forming a wedge shape of a narrow end progressively widening to a wide end in a direction of travel of the movable member. With the opposed wheels of the movable member respectively at opposite sides of the wedge shape member, the tracks of the wedge shape member engage and impart a spreading strain to the opposed wheels as the movable member moves in the direction of travel. The opposed wheels of the movable member comprise a deformable material to absorb the kinetic energy of the movable member. The tracks of the stop additionally may have undulating features comprising concave and convex surfaces in the direction of motion.
    • 提供安全止动件用于停止具有至少一组用于夹紧轨道的相对的轮的可动构件。 止动件在每个相对侧上具有形成狭窄端部的楔形状的轨道,其沿着可动构件的行进方向逐渐变宽到宽端。 由于可移动部件的相对的轮分别位于楔形部件的相对侧,所以当可移动部件沿行进方向移动时,楔形部件的轨道与相对的车轮接合并施加铺展应变。 可移动构件的相对的轮包括可变形材料,以吸收可移动构件的动能。 停止的轨道还可以具有包括在运动方向上的凹面和凸面的起伏特征。
