  • Patent number: 11351506
    Abstract: A bubble generation device intermittently generates large bubbles in a liquid phase. The bubble generation device includes a bubble storing container, a pivot, and a pair of edge portion receivers. The bubble storing container stores bubbles generated by a gas supply nozzle in the liquid. The pivot allows the bubble storing container to pivot thereon, thereby releasing the large bubbles from the bubble storing container. The pair of edge portion receivers receives and blocks an edge portion of the bubble storing container to limit pivot of the bubble storing container. An inside of the bubble storing container is partitioned by a partition that is installed in an axial direction of the pivot.

  • Patent number: 11130100
    Abstract: An eductor includes an adjustable air inductor assembly connected to a source of outside air or other fluid. As liquid flows through a constricted orifice of the eductor, the venturi effect creates a vacuum or low pressure zone that draws inducting fluid through the inductor assembly and infuses such fluid into the liquid driven or transmitted through the eductor. The fluid inducted liquid is then discharged by the eductor into a body or contained volume of water. Improved aeration and fluid flow control, as well as reduced algae growth are achieved without extraneous mechanical equipment. Increased turbulent liquid flow is produced, for example, to more effectively clean dirt and debris from water recirculating swimming pools, fish tanks and similar environments.

  • Patent number: 8960648
    Abstract: An arrangement for removing dust from the atmosphere during cleaning of a generally flat surface, such as floor, includes a reservoir for providing water to a nozzle. Also included is an air compressor and a compressed air tank. Compressed air is provided in a controlled manner at an elevated pressure to the nozzle to reduce the water to minute droplets which absorb/encapsulate the dust particles and deposit them on the floor surface under the influence of gravity. A manual or automatic pressure regulator coupled to the outlet of the compressed air tank allows for selecting the air velocity and the size of the water droplets to match the size of the dust particles to increase the extent of dust removal. This dust removal approach can be used with virtually any type of generally flat surface and the compressed air has a siphoning effect to increase the water droplets produced and the dust particles removed.

  • Publication number: 20130108760
    Abstract: An inline carbonation apparatus includes a fluid tube having an inner diameter. A water flow control module is connected to a water source. At least one water orifice is linked to the water flow control module and is attached at one end of the fluid tube. The water orifice includes a plurality of holes atomizing water passing therethrough. A carbon dioxide source is connected to a carbon dioxide valve. The carbon dioxide solenoid valve is connected to a carbon dioxide regulator that is coupled to a carbon dioxide orifice and attached to the fluid tube in a spaced relationship from the water orifice. The atomized water has a pressure less than the carbon dioxide such that carbon dioxide is absorbed into the water forming carbonated water having a specified volume of carbonation. The water control module regulates a water flow rate into the inline carbonation apparatus.

  • Publication number: 20120267804
    Abstract: A room humidifying apparatus is provided which operates with minimum cost and without any electrical power. The humidifier is located so as to make use of a stream of air coming from a register. The humidifier has a casing carrying a main water tank, a water pan and an evaporative filter element which are located in the casing. The tank drips water onto the filter element, which has a lower portion located in the water pan to collect any excess water dripping down the filter element and also to moisten it with capillary effect. Heated air from the register becomes humidified on passing through the filter element. The water tank can be filled manually from the top or be detachable and filled through a bottom refill opening. Alternatively, the water tank can be connected to a water source with a valve to regulate the flow of water into the water tank. The water tank may be balanced so as to displace, for example tilt, from a first position when it contains water to a second position when it is empty.
