    • A composition of matter suitable for increasing the viscosity of liquids comprises tendrillar carbonaceous material (TCM) having a ultra low bulk density of less than about 0.1 g/cm.sup.3 and comprises intertwined tendrils having a diameter (number average) of from about 0.05 to about 0.2 micron and a length (number average) to diameter (number average) ratio greater than about 10, the tendrils comprising carbon fibers and an iron metal component dispersed throughout the carbon fibers as nodules that are intimately associated with and at least partially bonded to the carbon fibers, the tendrillar carbonaceous material comprising from about 0.1 to about 5% by weight iron. The TCM can be used as a viscosifier and for suspending solids in such applications as drilling muds, lubricating oils and greases. The TCM can be prepared by disproportionating carbon monoxide in the presence of iron contained in a blend of (1) previously formed TCM and (2) iron containing particles.

    • A manually operable "bubble" button for an amusement device, such as an arcade game, includes inner and outer nested, generally cup-shaped members formed of suitable plastic material. The inner member has an annular flange which seats on an annular shoulder of the outer member to limit the depth of insertion so that the concave wall portions of the members are spaced apart. Circumferentially spaced ribs on the inner member engage the outer member to center the members and a locating tab on the inner member seats in a recess in the outer member to ensure proper relative orientation of the members. An indicium is disposed between the inner and outer members, preferably being fixed to the inner member, at least the outer member being substantially transparent to visible light so that the indicium can be seen therethrough. The members are fixed together adjacent to their open ends.

    • This invention relates to the novel method for stabilizing the pressure sensed by the downstream-facing port of a pitot tube type flowmeter over a broad flow range, thereby providing a stable and repeatable flow coefficient. The invention comprises localizing the areas of boundary layer separation across deflecting surfaces located upstream of said port by sharply contouring the edges thereof and directing the flowing stream thereacross, and preventing reattachment of said boundary layer by positioning and contouring the surfaces containing said port downstream of said sharply contoured edges so as to continuously lie within the wake of the fluid flowing around the latter over a broad range of flow rates. The invention also encompasses the improved averaging pitot-type flowmeter characterized by flow deflecting means having sharply contoured edges on both sides thereof effective to fix the location at which boundary layer separation occurs over a broad range of laminar and turbulent flow conditions, an upstream-facing impact surface shaped to direct the flowing fluid across said sharply contoured edges, and a downstream-facing surface containing a port for sensing downstream pressure so contoured and positioned relative to said sharply contoured edges as to cooperate therewith in preventing reattachment of the boundary layer under varying flow conditions.
    • 本发明涉及一种用于在宽流量范围内稳定由皮托管式流量计的下游端口感测到的压力的新颖方法,从而提供稳定且可重复的流量系数。 本发明包括将边缘层分离的区域定位在位于所述端口上游的偏转表面上,通过锐利地轮廓化其边缘并引导其流动,并防止所述边界层重新附着,并通过将包含所述端口的表面 尖锐的轮廓边缘,以便在较宽的流量范围内连续地位于流体周围流动的流体之后。 本发明还包括改进的平均皮托托型流量计,其特征在于具有在两侧具有锐利轮廓边缘的流动偏转装置,其有效地固定在宽范围的层流和湍流条件下发生边界层分离的位置,上游侧 冲击表面成形为将流动的流体引导穿过所述锐利轮廓的边缘,以及包含用于感测下游压力的端口的下游侧表面,所述下游压力相对于所述锐利轮廓的边缘进行成形和定位,以便与其配合以防止在变化的边界层的重新附着 流量条件。

    • Continuous row average sampling of a stationary source gas stream is accomplished with the aid of a tubular sampling probe extending across the gas stream flow path in a transverse plane of the path and having sampling port means forming a longitudinally extending sampling port row through which gas is drawn into the probe. The sampling port means preferably comprise one or more ports spanned by a porous filter medium and are designed to produce a pressure drop which is substantially uniform along the port row and relatively large in comparison to any internal or external pressure changes which occur along the probe so as to maintain a uniform gas sampling rate along the port row.
