    • An amphibious vehicle that may be driven directly between land and water includes a vehicle with an opposed pair of flotation side hulls and a rear hull. The side hulls are movable between a stowed position above the vehicle and a lowered deployed position outboard thereof. Each side hull is mounted by arm assemblies including an upright bracket fixed to the vehicle and an arm pivotally connected to the bracket that can be extended or retracted linearly by actuators to raise and lower the side hulls. A locking mechanism prevents the extended side hulls from moving laterally but allows vertical adjustment thereof. The side hulls may be horizontally adjusted between compact contracted and extended protracted positions. The rear hull assembly is pivotally mounted to the back of vehicle permitting raising and lowering thereof and includes jet drives providing propulsion for water operation.

    • The disclosed HPLC flow schematic back-flushes the guard column with mobile phase once every operating cycle, the regular cleaning maintaining its effectiveness and useful life. This mobile phase flow reversal is accomplished by imposing a two position multiple port switching valve between the guard and separation columns. In one valve position, the mobile phase is pumped in one flow direction through both the separation and guard columns, but the switched valve maintains the same flow direction only through the separation column and reverses the mobile phase flow direction through the guard column, for effectively cleaning the guard column. Moreover, the mobile phase back flow is directed over the emptied sample drawing needle for cleaning it to reduce possible sample cross contamination. The improved flow circuits use basically only the typical HPLC system components, except for some insignificant modifications from existing injector designs.
    • 所公开的HPLC流程示意图每个操作循环一次性地将流动相反冲洗保护柱,定期清洗保持其有效性和使用寿命。 该流动相流逆转通过在保护和分离柱之间施加两位多端口切换阀来实现。 在一个阀位置,流动相通过分离柱和保护柱通过一个流动方向泵送,但开关阀仅通过分离柱保持相同的流动方向,并将流动相流动方向反向通过保护柱,以有效地 清洁保护柱。 此外,流动相回流被引导到空的样品拉伸针上,以清洁它,以减少可能的样品交叉污染。 改进的流量回路基本上仅使用典型的HPLC系统组件,除了现有喷油器设计的一些不太重要的修改之外。

    • A container for holding fluids in isolation includes an outer container and two deformable inner containers carried within the internal space of the outer container. The outer container is provided with a view port enabling the user to visually examine the inner containers. The inner containers have respective ports communicating with their interiors. As fluid is withdrawn from the first inner container its volume is reduced so that the second container may receive a like amount of fluid. The second inner container may hold colorants or absorbents. The container may be used with various chemical applications, such as high performance liquid chromatography or fluid injection analysis, wherein supply fluid is withdrawn from the first inner container, used, and returned as waste fluid to the second inner container so that the overall volume of fluids remains relatively constant.

    • The disclosed HPLC column is formed with overlying concentric inner and outer tubes. The flow path is established via the inner tube bore that holds packed absorbent, end filters and capping sealing members, and end coupling members cooperate with the inner tube at its ends. The sealing and end coupling members have conventional configurations for establishing a sealed connection with capillary lines and their fittings, for the series flow testing use through the column. The inventive method and manner of assembly provides that the outer tube overlies all of the inner tube and both sealing members, but only part of each end coupling member. The ends of the outer tube are then deformed radially inward to become mechanically interlocked with the end coupling members, as the column, holding also the filters and sealing members within the inner tube.

    • This modified HPLC instrument has the HPLC pump force only solvent through the serial flow line including a sampler, column, and detector; while buffer is discharged into the solvent from a syringe pump via a tee connection in the flow line downstream from the HPLC pump. A stepper motor drives the syringe pump at a discharge rate to yield an intended buffer/solvent dilution ratio compared to the steady HPLC pump flow rate. A pressure transducer detects variances of the flow line pressures, and servo controls the stepper motor for increasing the flow rate upon increased pressures and decreasing the flow rate upon decreased pressures, to hold the dilution ratio constant.

    • This linear drive has cooperating threaded screw and follower components suited to be rotated relative to one another to create a corresponding axial shift between the components, where the follower is improved by having spaced drive members each threadably cooperating with the screw and capable of carrying the maximum axial linear drive force between the components. Anti-friction structures support the drive members for allowing relatively effortless component rotation, frictionwise, even under this maximum driving force. Ramp structures cyclically expand and contract the axial separation between the drive members, which both generates the maximum axial driving force and effectively shifts the axial driving force alternately between the drive members. The force-carrying drive member will be thread friction bound relative to the screw, and the substantially loadfree drive member will be easily rotatable with the follower rotation suited to be axially advanced along the screw. Relative component rotation and repeated expanding and contracting shift cycles incrementally and alternately advance, with an inch-worm like action, the drive members along the screw to provide the axial shift and force generation between the components, the loadfree drive member being advanced and the force-carrying drive member remaining stationary relative to the screw.

    • A magnetic reciprocating pump includes a tube having ends defining intake and discharge ports, first and second magnetic plungers axially aligned within the tube of corresponding cross section for reciprocation therewithin, and a plurality of longitudinally spaced coils circumscribing the tube for driving the plungers axially when electrically energized. A gap is defined between the plungers so that the first plunger is slidable between one tube end and the second plunger and the second plunger is slidable between the other tube end and the first plunger. The first plunger closes one port when moved thereagainst and has a peripheral flow path permitting flow when moved away. The second plunger closes the other port when moved thereagainst and has an outer peripheral flow path and a communicating inner axial flow path permitting flow when moved away. The plungers when moved together close the second plunger axial flow path.
