    • 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).

    • A trailer with expandable sides and retractable wheels used for performing on site vehicle maintenance and repair services. The trailer has a rectangular frame mounted on wheels with a conventional trailer coupler for attachment to a towing vehicle. The wheels are pivotally mounted to the frame, the wheels being locked in a ground engaging position for towing the trailer, and being unlocked so that the frame may be lowered into a ground engaging position by a plurality of hydraulic cylinders for the servicing of vehicles. The frame includes a plurality of crossbeams. A pair of side extenders telescope into the front, rear and center crossbeams so that the width of the trailer may be extended by hydraulic cylinders with the frame in a ground engaging position. The trailer includes a two-post hydraulic vehicle lift for raising the vehicle to be serviced.
    • 具有可扩展侧面和伸缩轮的拖车,用于执行现场车辆维修和维修服务。 拖车具有安装在具有常规拖车联接器的轮子上的矩形框架,用于附接到牵引车辆。 轮子可枢转地安装在框架上,车轮被锁定在用于牵引拖车的地面接合位置,并且被解锁,使得框架可以被多个用于维修车辆的液压缸下降到地面接合位置。 框架包括多个横梁。 一对侧向延伸器望远镜伸入前,后和中心的横梁,使得拖车的宽度可以由液压缸延伸,框架处于接地位置。 拖车包括一个两柱液压车辆升降机,用于提升待维修的车辆。

    • 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,其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,该移动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。
