摘要:
Pieces of furniture which have a single configuration of parts, but that configuration allows for two different positions into which they may be placed and those positions provide different functionality from each other. Thus, the furniture has two different uses, but switching between them simply requires placing the piece of furniture in a different arrangement instead of removing or adding parts or moving parts relative to each other. Specifically, the piece of furniture is generally “flipped-over” to switch between arrangements.

A water inlet system for an aquarium is disclosed along with a siphon stopper and a method of attaching the system to an aquarium. The water inlet system is designed to pass through an aperture formed in a sidewall of the aquarium. A tubular member is connected to a pump which can supply water from a reservoir to the aquarium. The tubular member passes through the aperture and into the aquarium. An adapter having a spout is connected to one end of the tubular member. In addition, a siphon stopper is secured to the adapter, above the spout, and serves to break any back siphon that may develop should the water line in the aquarium drop below a predetermined point. The method includes the steps of attaching the water inlet system to the aquarium.

A cleaning device for aquariums comprises a water-tight enclosure configured to be submerged under water and a water pump comprising an inlet for receiving water and an outlet pipe for expelling water. The outlet pipe comprises a central axis. A power source is disposed within the water-tight enclosure for powering the water pump. An adjustable nozzle comprises a nozzle outlet in fluid communication with the outlet pipe, and the adjustable nozzle is configured to be rotated about the central axis of the outlet pipe to selectively adjust a position of the nozzle outlet. In one example, water volume flow or water velocity flow expelled from the nozzle outlet can be selectively adjusted via rotational adjustment of the adjustable nozzle relative to the outlet pipe.

A modular fish tank includes a chamber including a front section and a back section. The front section of the chamber includes a spherical bulb extended out from the chamber and is configured to magnify objects in the back section of the chamber when the chamber is filled with water. In an arrangement of two or more modular fish tanks, at least one of the modular fish tank in the arrangement is in a contact position next to another one of the modular fish tank in the arrangement. A viewing station for the modular fish tank includes one or more levels, and the levels each includes one or more modular fish tanks.

A removable wavemaker having a self-supporting structure for use in a wave tank has an integrated mounting structure for mounting on a frame of an open top of the wave tank, a linear motor positioned above a waterline in the wave tank having a forcer containing activation coils that is driven in reciprocation motion by electromagnetic interaction with an array of permanent magnets contained in a tubular support structure on which the forcer is configured to slide, and a vertically-oriented wave board mounted on a lower part of the integrated mounting structure below the waterline for generating waves within the wave tank. The forcer is supported on a movable carriage that rides on a rail fixed to the integrated mounting structure and is coupled to the wave board.

An automated fish tank cleaning assembly automatically cleans a fish tank. The assembly includes an upper housing and a processor coupled to and positioned in the upper housing. Support arms are extend from the upper housing supporting the upper housing on a fish tank. Each of a plurality of rollers is coupled an associated one of the support arms. Each of the rollers is operationally coupled to the processor wherein the rollers move the upper housing relative to the fish tank. A lower housing is coupled to the upper housing by a connection conduit extending between the upper housing and the lower housing. A plurality of cleaning arms is coupled to and extends from the lower housing. Each of a plurality of brushes is coupled to a distal end of an associated one of the cleaning arms relative to the lower housing.
摘要:
In a process for the dual use of packaging for a fish-related product such as fish food or a fish-related consumable product normally dispensed into an aquarium, a package including a compartment is filled with the fish-related product which is then dispensed until depleted. The dual use package is then placed within the aquarium and utilized as a decorative ornament. In this regard, the dual use package may be reconfigured for use as a decorative feature within the aquarium, and ballast may be added to the ornamental container before being submerged.

An aquarium acclimation device and method reduce stress and shock which may occur during transition of marine livestock including fish, invertebrates, corals, etc., from a store, online, or wholesaler, to an owner's aquarium. The acclimation device includes tubing, a squeeze bulb, a drip counter, and a rolling clamp. A “J” tube is hung over an edge of the aquarium with one end reaching into water in the aquarium and an opposite end hanging outside the aquarium. The squeeze bulb is connected to the outside end of the “J” tube for initiation of a flow of the aquarium water from the aquarium and a clear squeeze bulb may further provide the drip counter. The rolling clamp and drip counter allow a gradual, observable, and controlled flow for a gradual controlled transition to the aquarium environment.
摘要:
A cleaning device for cleaning the back side of a panel with a control member and a cleaning member, which is separate from the control member and which has a base member and two blades disposed thereon. The control member and the cleaning member interact magnetically through the panel, so that the cleaning member disposed on the back side of the panel can be guided along the panel while pressing the cleaning edges of both blades on the back side of the panel by means of the control member disposed in a manner corresponding to it on the front side of the panel. The two blades may be of different lengths and, by suitable geometry and arrangement of the blades or of magnetic elements, the shorter of the two blades exerts a greater pressing force on the panel with its cleaning edge than does the longer.
