Abstract: A hydrocarbon wax product from a HCS slurry comprising liquid synthesis product and catalyst particles is purified by circulating the slurry from a synthesis zone with a first temperature through a treatment zone with a second temperature in which a hydrogen-containing treatment gas contacts the slurry.  The gas treatment removes impurities from the hydrocarbon wax product and also removes catalyst de-activating species which may be present in the slurry.  Purified wax product is separated and removed from the treated slurry via wax withdrawal means. This avoids or minimizes the need for further treating the wax product. Remaining treated slurry may be returned to the synthesis zone.

Abstract: A closure assembly for a container including an internally-threaded annular flange, an externally-threaded closure plug that is received by the annular flange, and an annular gasket positioned between the annular flange and the closure plug for establishing a sealed interface. The container includes a container end panel that is formed over and around a portion of the annular flange and provides an inner axial wall that is positioned between the annular flange and the annular gasket. The clearance between the closing plug and the inner axial wall relative to the size of the annular gasket determines the degree of radial compression of the annular gasket as the plug is threaded into the flange. A radial lip of the plug is designed to contact an upper surface of the container end panel that is formed over the flange as a visual indication when the required tightening torque of the plug within the flange has been reached.

Abstract: In the blade structure in a gas turbine, inlet included angles are made large. As a result, a curve of a relative relationship between incidence angles ic1 and is1 and pressure loss becomes mild. Entrance metal angles, which are formed by an axial direction of the gas turbine and a tangential direction to a camber line at the front edge of the stationary blade, are made small. As a result, it becomes possible to make the incidence angles small. Chord length of a tip portion of a moving blade is made large. As a result, it becomes possible to make small the deceleration on a rear surface of the tip portion of the moving blade. Accordingly, it becomes possible to make the pressure loss small, and therefore, it becomes possible to improve the turbine efficiency.

Abstract: System and methods (Fig.6) for improved uplink signal detection where when a mobile device detects signaling indicating the presence of a packet for that mobile device from a network node (S10), the mobile device may transmit one or more NACKs in a sub-frame before the one in which the mobile device would transmit normal ACK/NACK for the packet(S11-S-12). Additionally, the mobile device may transmit one or more NACKs in the sub-frame immediately following the normal ACK/NACK for a packet (unless a packet was transmitted in the immediately following sub-frame and successfully decoded by the mobile device, in which case an ACK would obviously be transmitted) (S13). Therefore, extra uplink (UL) interference is eliminated. Moreover, the amount that a network node must offset its ACK/NACK decision threshold is significantly reduced.  This results in a reduction of required ACK power by a mobile device.
