    • A method for detecting the presence of an acid gas in a formation fluid from a subterranean formation comprises (a) lowering a coring assembly into a wellbore. The coring assembly including an outer core barrel and an inner core barrel disposed within the outer core barrel. The inner core barrel has an upper end, a lower end opposite the upper end, and a core sample chamber extending axially from the lower end. In addition, the method comprises (b) capturing a core sample from the subterranean formation within the sample chamber. Further, the method comprises (c) raising the coring assembly to the surface after (b). Still further the method comprises (d) contacting a formation fluid in the sample chamber with at least one detector during (c). Moreover, the method comprises (e) detecting the presence of a formation acid gas in the formation fluid with the at least one detector during (c).
    • 用于检测来自地下地层的地层流体中酸性气体的存在的方法包括(a)将取芯组件降低到井眼中。 所述取芯组件包括设置在所述外芯筒内的外芯筒和内芯筒。 内芯筒具有上端,与上端相对的下端,以及从下端轴向延伸的芯试样室。 此外,该方法包括(b)从样品室内的地层中捕获核心样品。 此外,该方法包括(c)在(b)之后将取芯组件提升到表面。 此外,该方法包括(d)在(c)期间使样品室中的地层流体与至少一个检测器接触。 此外,该方法包括(e)在(c)期间用至少一个检测器检测地层流体中地层酸性气体的存在。

    • A low battery indicating device is disclosed for indicating that a battery has low power. The device includes an indicator having a body movable between a retracted, unactuated position and an extended, actuated position. The indicator is visible when in the actuated position. The device also includes means for biasing the indicator towards the actuated position, and latch means cooperating with a portion of the body of the indicator, when the latch means is in a stop position, to hold the indicator in its unactuated position. The latch means is movable between the stop position and a go position which frees the indicator to move, under operation of the biasing means, to the actuated position. A memory alloy wire is mechanically associated with the latch means so as to leave the latch means in the stop position when the memory alloy wire is in a relaxed state and to move the latch means to the go position when the memory alloy wire is in a contracted state caused by heating of the memory alloy wire. Electrical sensor circuitry is in communication with the memory alloy wire. The electrical sensor circuitry is adapted to detect when the battery means has low power and cause heating of the memory alloy wire to cause it to change to the contracted state and thereby move the latch means to the go position.
    • 公开了一种低电量指示装置,用于指示电池具有低功率。 该装置包括指示器,该指示器具有可在缩回的未致动位置和延伸的致动位置之间移动的主体。 当处于致动位置时,指示器是可见的。 该装置还包括用于将指示器朝向致动位置偏置的装置,以及当闩锁装置处于停止位置时与指示器的主体的一部分配合的闩锁装置,以将指示器保持在其未致动位置。 闩锁装置可在停止位置和移动位置之间移动,该释放位置在偏置装置的操作下使指示器移动以移动到致动位置。 存储合金丝与闩锁装置机械地相关联,以便当记忆合金线处于松弛状态时使闩锁装置保持在停止位置,并且当记忆合金线处于松弛状态时将记忆合金线移动到停止位置 记忆合金丝由加热引起的收缩状态。 电传感器电路与记忆合金线连通。 电传感器电路适于检测电池装置何时具有低功率并且引起存储合金线的加热,使其变为收缩状态,从而将闩锁装置移动到转向位置。

    • A mobile vehicle service trailer provides a portable maintenance facility for motor vehicles (passenger cars, pickup trucks and sport utility vehicles, etc.) without need to transport the vehicle to a maintenance facility at a fixed location. The present trailer has rearwardly disposed wheels and laterally extendible ramps, enabling the trailer to be positioned laterally at the front or rear of the vehicle needing service and the vehicle to be positioned laterally across the trailer. This configuration provides for ease of loading and unloading the vehicle to and from the trailer in cramped parking situations, such as parking lots and garages, etc. The rear wheels of the trailer are pivotally mounted, allowing the trailer body to be lowered to the underlying surface for placement of a vehicle thereon. A specially formed trailer hitch may be provided for the towing vehicle, allowing the hitch ball to be lowered to the underlying surface to lower the trailer tongue without disconnecting the trailer from the towing vehicle. Corner jacks are provided for raising and lowering the trailer body as desired. A forward and a rearward hydraulically powered lift hoist are provided on the trailer body, for raising the vehicle for access to the underside thereof for maintenance operations (oil changes, etc.). The present trailer also includes a hydraulic power supply for operating the corner jacks, vehicle hoists, and for raising and lowering the ramps as desired.
    • 移动车辆拖车为机动车辆(乘用车,皮卡车和运动型多功能车等)提供便携式维护设施,而不需要将车辆运输到固定位置的维护设施。 本拖车具有向后设置的轮子和横向可延伸的坡道,使得拖车能够横向定位在需要服务的车辆的前部或后部,并且车辆横向跨越拖车定位。 这种配置提供了在狭窄的停车场地(例如停车场和车库等)中容易地将车辆装载和卸载在拖车上。拖车的后轮被枢转地安装,允许拖车主体被降下到底部 用于在其上放置车辆的表面。 可以为牵引车提供特别形成的牵引车钩,允许牵引球降低到下面的表面,以降低拖车舌头,而不会使拖车与牵引车辆断开连接。 根据需要提供角落千斤顶以提升和降低拖车主体。 在拖车主体上设有一个向前和向后的液压动力提升提升机,用于升起车辆进入其下侧进行维修操作(换油等)。 目前的拖车还包括用于操作角落千斤顶,车辆起重机以及根据需要升降斜坡的液压动力源。
