119263000 | Aerator | 10 |
20080251029 | DIFFUSER AND ANCHOR - An aquarium aerator unit includes an anchor that is weighted by an aquarium bedding material. The anchor includes a lower portion that has a defined edge and spaced-apart side sections proximate to the lower portion. An inner space is formed between the side sections above the lower portion. The defined edge provides a shovel edge that eases the lower portion into the bedding material and the inner space storing the bedding material to enhance stability and aesthetics. | 10-16-2008 |
20090139458 | Aerating or air bubble collecting device - An aerating device for an aquarium includes a carrier, a pumping device attached to the carrier and having a motorized impeller for pumping a water and for minimizing the air in the water into a number or reduced air bubbles, a siphon tube coupled to the pumping device and having a tube member engaged into the aquarium for allowing the water to be drawn into the siphon tube and drawn into the carrier by the impeller, and a partition engaged into the carrier and having a passage for collecting the bubbles, and a receptacle disposed above the passage of the partition for receiving and collecting the bubbles and the dirt or protein carried by the bubbles. | 06-04-2009 |
20100043718 | Submerged motor for aquarium - A submerged motor for use in an aquarium is disclosed to include a housing one or water input ports and two water output ports, a driving mechanism having a left-sided water pumping device and a right-sided water pumping device for pumping water through the water input ports and the water output port in different directions, and an electric controller electrically connected with the driving mechanism for controlling operation of the left-sided water pumping device and the right-sided water pumping device to change direction and flowing speed of the pumped water. | 02-25-2010 |
20100154717 | OXYGENATING IN AQUACULTURE - The invention relates to a device for supplying gas into water in sea cages, tanks or ponds with a pump and a dissolver for contacting the gas with the water. For higher efficiency and better handling the pump is a submerged pump. | 06-24-2010 |
20110067643 | Air vent tube for aquarium and fish tanks special usage and strengthen - I am Wu Zheng Yi, have invented AIR VENT TUBE FOR AQUARIUM AND FISH TANKS SPECIAL USEGE AND STRENGTHEN (Air Vent tube). This invention, Air Vent Tube (AVT), is for aquarium products and fish tanks using and strengthen. This Air Vent Tube is the best suitable for aquariums and fish tanks to increase air and oxygen in the water in fish tank, because fishes in the fish tanks need more oxygen in the water. The structure of Air Vent Tube is the idea created at least two surfaces and three surfaces, which are formed right angle shape and triangle shape. There is a long hole in the Air Vent Tube and the long hole connects with the short outflow hole in the large surface of the Air Vent tube. Along the Air Vent Tube length extension and view as long shape. These invented AVT can be made of glass material or other materials. | 03-24-2011 |
20130333627 | Temperature-Controllable Aquaculture Apparatus - An inexpensive, easily manufactured aquaculture apparatus featuring a water temperature control feature, useful for studying the effect of water temperature changes on the viability of aquatic species. The apparatus is useful to, for example, study the potential effect of global warming and rising ocean water temperatures on various aquatic species. | 12-19-2013 |
20140245962 | DISSOLVED GAS SUPPLYING DEVICE - A problem with conventional rearing apparatuses for deep-sea organisms was difficulty in supplying dissolved gas into water in an appropriate amount. | 09-04-2014 |
20140311416 | Dissolved Oxygen Control System for Aquaculture - Some embodiments provide a recirculating aquaculture system for aquatic life. The system includes a culture tank, a sensor configured to measure a current dissolved oxygen level in the culture tank, a variable speed pump configured to circulate water through the culture tank, and a controller in communication with the sensor and the variable speed pump. The controller is configured to retrieve a dissolved oxygen threshold level and a maximum gas to liquid ratio in the culture tank, retrieve the current dissolved oxygen level, compare the current dissolved oxygen level with the dissolved oxygen threshold level, and automatically increase one of a current water flow rate and a current oxygen flow through the system when the current dissolved oxygen level is less than the dissolved oxygen threshold level. | 10-23-2014 |
20140311417 | Method for Regulating Energy Consumption in Aquaculture Systems - Some embodiments provide a recirculating aquaculture system for aquatic life. The system includes a culture tank, a plurality of sensors configured to control parameters in the system, a variable speed pump configured to circulate water through the culture tank, and a controller in communication with the plurality of sensors and the variable speed pump. The controller is configured to prioritize the plurality of control parameters based on a hierarchy list, select a highest priority control parameter, determine potential actions for each of the plurality of control parameters, and select a highest priority action based on at least one of the hierarchy list, the highest priority control parameter, a current power consumption of the variable speed pump, time of day, feeding cycle of the aquatic life, and resting cycles of the aquatic life. The controller is also configured to execute the highest priority action. | 10-23-2014 |
20160113250 | AERATOR FOR ENHANCING AQUATIC LIFE BY CREATION OF MAGNETIC WATER - An aerator having a rotatable shaft that is secured to a magnetic driving element and a plurality of plates positioned in spaced apart relation to the magnetic driving element. Each plate and the magnetic driving element have a plurality of elongated openings about their peripheries to enhance aerodynamics and thus oxygen content within the aerated water. Simultaneously because of the rotation of the magnetic driving element a magnetic field is created in the water providing optimum conditions for the growth of algae and biofloc within the water. | 04-28-2016 |
