    • An air-operated sound producing device includes a main housing including a downwardly curved reed-plate formed thereon with a plurality of variously sized sound channels formed therein, a reed assembly having at least two vibratable reeds formed thereon, and a means to secure the reed assembly over the downwardly curved reed-plate. The reed-plate provides a portion between the sound channels for center support and vibration of the reed. The reed assembly of the sound producing device is vibratable in whole, or in part, over multiple sound channels. The device is particularly suited for the use of thin, relatively wide reeds. Further, the device provides for the adaptation of a variety of interchangeable variously sized reeds produced from a single piece of material. The disclosed novel device can produce a wide variety of unusual and desirable sounds of considerable volume and has applications to hand-held musical instruments, toys, novelty items, and wildlife attraction devices.
    • 一种气动声音产生装置,包括:主壳体,包括形成在其上的多个不同尺寸的声音通道的向下弯曲的簧片,具有形成在其上的至少两个可振动簧片的簧片组件,以及用于固定簧片的装置 组装在向下弯曲的簧片上。 簧片提供声道之间的一部分用于中心支撑和筘振动。 声音产生装置的簧片组件可全部或部分地在多个声道上振动。 该装置特别适合使用薄而较宽的芦苇。 此外,该装置提供了由单一材料制成的各种可互换的各种尺寸的芦苇的适应性。 所公开的新颖装置可以产生相当大体积的各种不寻常和期望的声音,并且应用于手持乐器,玩具,新奇物品和野生动物吸引装置。

    • An improved gas analyzer for analyzing the concentrations and amounts of one or more different gases in drilling mud returning from a borehole is disclosed. An oil well drilling rig re-circulates the drilling mud by continuously pumping it through a gas separation means. The gas separation means generally includes a fluid stop, a bubble jar and a dririte chamber in order to separate the gases from the drilling mud. A gas sample from these separated gases can be mixed with a carrier gas and are conveyed to gas analyzing means where the concentration of the different hydrocarbon components of the gases in the mud can be continuously measured.
    • 公开了一种改进的气体分析仪,用于分析从井眼返回的钻井泥浆中的一种或多种不同气体的浓度和量。 油井钻机通过连续泵送钻井泥浆通过气体分离装置来重新循环钻井泥浆。 气体分离装置通常包括流体阻挡件,气泡罐和驱动室,以将气体与钻井泥浆分离。 来自这些分离的气体的气体样品可以与载气混合并输送到气体分析装置,其中可以连续地测量泥浆中气体的不同烃成分的浓度。
