    摘要： An exhaust gas turbocharger for an internal combustion engine has a flow control gate that is timely pivotal and located within the exhaust gas inlet downstream of the flow splitter. Control is provided to timely pivot the flow control gate toward the turbine rotor and thus provides an initial high velocity spin to the rotor when turbo charged boost pressure is demanded from an adjustable direction flow control valve. The control valve uses boost pressure from the compressor to timely actuate a piston and lever connected to the pivotal flow control gate, or a signal from an engine control module (ECM) can be directed to a hydraulic, pneumatic or electrical actuator having a reciprocal control rod connected to the flow control gate.

    摘要： A multi-pulse rocket is equipped with a thermally insulating barrier that serves as a rupture disk or a movable plug or plate separating staged propellant grains. When a rupture disk it used, the disk can be equipped with a pyrotechnic actuator to weaken the disk upon command, enabling the propellant grain on the fore side of the disk to burst the disk at a relatively low pressure when ignition of the propellant grain is needed for additional thrust. Rupturing of the disk can also be controlled by attitude maneuvering ports on the fore side of the barrier whose open or closed conditions are controlled by independently operable closures. When a movable plug is used, the plug is movable between a closed position separating rocket chamber into subchambers isolating the propellant grains from each other and an open position allowing the flow of combustion gas between the two subchambers to achieve additional axial thrust. In all cases, the barrier when intact serves to contain both propellant grains regardless of whether one or both is ignited. The propellant grain on the fore side of the barrier can thus be used for either axial thrust augmentation or for attitude maneuvering.

    摘要翻译： 多脉冲火箭配备有绝热障碍物，其用作破裂盘或分离分段推进剂颗粒的活动塞子或板。 当使用破裂盘时，盘可以装备有烟火执行器，以便在命令时削弱盘，使得当推进剂颗粒点燃时点燃盘片的前侧上的推进剂颗粒以相对低的压力爆裂， 需要额外的推力。 盘的破裂也可以通过位于屏障前侧的姿态操纵端口来控制，其开放或关闭状态由独立可操作的闭合来控制。 当使用可移动塞子时，塞子可以将分离火箭箱的关闭位置与将推进剂颗粒彼此隔离的子室和允许两个子室之间的燃烧气体流动以获得额外的轴向推力的打开位置之间移动。 在所有情况下，完好无损的屏障用于包含两种推进剂颗粒，而不管其中一种或两种是否被点燃。 因此，阻挡物前侧上的推进剂颗粒可用于轴向推力增加或姿态机动。

    摘要： A safety enclosure for a human worker positioned on a ladder, comprising a bracket connectable to first and second preselected rungs of a ladder, having a longitudinally extending central portion preselected in length to span at least two adjacent rungs of the ladder. A continuous open hoop-like member having a preselected opening sized so as to freely encompass the midsection of a human worker is connected to the bracket means adjacent the first preselected rung. The hoop-like member has a pair of side portions extending normal to the bracket, and a back portion connecting the two side portions. Auxiliary hoop means connects the outboard ends of the side portions to the bracket and adjacent to the second preselected ladder rung. The bracket includes a first U-shaped hook-like portion sized to hook over and longitudinally engage the first rung. The bracket also includes, at the other end thereof, a U-shaped portion sized to snugly and normally encompass said second preselected rung. The safety enclosure further includes stabilizer means attached to the side portions and having members which may be moved normal to the bracket toward and adjacent to a building wall against which the ladder is resting.

    摘要： A data-storage cartridge has a rotary inner shell, or shutter, to selectively permit access to a data-storage disk disposed within the shell. The shutter is equipped with a wedge-shaped opening through which access to the data-storage disk is attained. A fabric liner is affixed to the inner surface of the shutter to isolate the disk from direct contact with the shutter. The ends of the liner extend beyond, i.e., overhang, the edges of the shutter which form the disk-access opening, thereby preventing direct contact between the data-storage disk and the edges.

    摘要： An improved method for the decarbalkoxylation of alkylated .beta.-keto esters to obtain high yields of ketones. In accordane with the method, decarbalkoxylation of alkylated .beta.-keto esters is accomplished by heating the esters in the presence of dilute aqueous alkali and an effective amount of a phase-transfer agent. The method produces commercially practical yields of ketone in a manner which is facile, economical and environmentally safe. Novel methylene-linked pyrethroid ketones produced from the improved method exhibit insecticidal activity against various agricultural pests.

    摘要： A vertically elongated chamber has a current of air blowing upwardly therethrough so that leaves deposited into the chamber are subjected to a combined effect of gravity and airflow and heavy stems of the leaves are thus oriented downwardly; conveyor means in the chamber translate the leaves laterally so that the leaves move, stem first, through an outlet passage at one side of the lower portion of the chamber. The leaves then fall onto a discharge conveyor with their stems oriented in the same direction. A zone of reduced pressure at the upper end of the chamber prevents the leaves being blown out the top of the chamber. Kicker means within the chamber above the conveyor means aid in separating leaves which may be stuck together.
