摘要： A conveyor assembly includes a plurality of idler pulleys over which a belt rolls. The idler pulleys are journaled in bearings in side walls of the conveyor assembly. The pulley includes a generally cylindrical center portion or shaft and a stub shaft that is removably mounted to end walls at each end of the pulley shaft. Each stub shaft has a radially disposed flange that is used to removably secure to the stub shaft to the pulley shaft. Additionally, at least one of the bearings for each idler pulley is mounted in an access panel. The access panel is removably mounted to the conveyor side wall and is sized and shaped, such that when they are removed from the conveyor side wall, the pulley stub shaft can be easily reached in order to be removed from the pulley, and the pulley itself can be easily removed from the conveyor, for repair or replacement.

摘要： 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 traversing 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 amplify the natural stop band. The transmitter is mounted transvere 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.
摘要翻译：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，用于对穿过钻孔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。发射机和接收机之间还包括一个无孔挡板滤波器，以放大自然停带。变送器安装在钻铤的纵向轴线上，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。

摘要： 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.
