Abstract: Apparatus for maintaining a clean environment in an aquarium. A false bottom having a perforate top and defining an open flow space thereunder is placed in an aquarium and is covered with a layer of gravel. An air-lift pump continuously pumps water out of the flow space and thereby circulates water downward through the gravel, and the gravel acts as a filter bed to collect wastes. A standpipe integral with the false bottom forms part of the airlift pump and defines an open flow channel of large capacity from beneath the false bottom through the filter bed. Periodically, e.g., once a week, water is discharged from the tank through the standpipe, preferably with a piston pump, so as to produce a strong pulsating, flushing flow downward through the gravel bed, which cleans the gravel and removes accumulated waste from the tank, without disturbing the gravel or any decorative plants of the like which may be present. The air lift pump desirably includes a bottom-slotted conduit extending transversely beneath the false bottom, an air inlet pipe at one end thereof, and an upstanding aerator pipe within the standpipe. This provides a two-stage pumping action, first, within the aerator pipe and, second, within the standpipe, which produces strong continuous circulation, and good aeration of the water.

Abstract translation: 用于在水族箱中保持清洁环境的装置。 具有穿孔顶部并且在其下方限定开放流动空间的假底部放置在水族箱中并且覆盖有一层砾石。 空气提升泵连续地将水从流动空间中抽出，从而使水向下循环通过砾石，并且砾石充当过滤床以收集废物。 与虚假底部一体的立管形成空气提升泵的一部分，并且通过过滤床从假底部下方限定大容量的敞开的流动通道。 周期性地，例如，每周一次，水通过立管从罐中排出，优选地用活塞泵排出，以便通过砾石床向下产生强烈的脉动，冲洗流，从而清除砾石并将积累的废物从 罐，而不打扰可能存在的砾石或任何类似的装饰植物。 空气提升泵理想地包括横向于假底部下方延伸的底槽导管，在其一端的进气管，以及立管内的直立通气管。 这提供了两阶段的泵送动作，首先是在曝气管内，其次在竖管内，产生强烈的连续循环，并且充分利用水。

Abstract: An apparatus for generating a wobble motion with a wobble body is disclosed. An endless band is secured to the wobble body for transmitting motion thereto. The endless band is formed of a flat circular ring band which is bent about axes parallel to two perpendicular diameters. In position, the endless band includes a symmetry plane which extends through one of the body suspension means. A drive mechanism secured to a frame imparts motion to the wobble body via the endless band. The wobble body is rotatably secured to a frame by suspension means.
