51 results about "Ebb and flow" patented technology

Ebb and Flow (also called Ebb and flood and flood drain) are two phases of the tide or any similar movement of water. The Ebb is the outgoing phase, when the tide drains away from the shore; and the flow is the incoming phase when water rises again. The terms are also common in figurative use.

Hybrid Hydroponic Plant Growing Systems

Hybrid hydroponic plant growing systems are designed specifically for urban home, community and small farm gardening without the need for arable soil or broadcast irrigation. The innovative hybrid hydroponic systems provide a “hybrid” growing environment including a limited, containerized amount of soil-like growing media combined with soluble fertilizer creating a hydroponic nutrient solution. The use of containerized growing media allows the units to be utilized regardless of the availability of arable soil, irrigation water, or runoff capacity. Multiple hydroponic techniques, such as drip system, nutrient wicking, ebb-and-flow, and / or deep water culture are combined to optimize plant nutrition at different stages of plant growth. Incremental fertilization, water monitoring, and drain systems are designed for easy use by non-professional gardeners. Water recirculation minimizes water use and fertilizer runoff. The units are easily adapted to solar and other off-grid power techniques.

Fender System for Vessels Which Allows Fenders to Self Adjust

The present invention provides a fender system that is applied to a dock piling or solid faced bulkhead in order to prevent damage to a marine vessel while the vessel is moored to a fixed or floating dock, or dock piling, or solid faced bulkhead. The fender is designed to uniquely rise and fall with the level of the tide such that the fender is always in the most suitable position for protecting the vessel's hull from coming into direct contact with the piling or bulkhead. Thus, this system is useful in waters in which there is a constant ebb and flow of the tide and is especially useful in areas experiencing a storm surge.

Channel shaped deep water tidal channel formed by means of 'bidirectional contraction effect'

The invention belongs to the field of marine traffic engineering, and in particular relates to a channel-shaped deep water tidal channel which is formed through dredging by using a 'two-way water control effect'. The technical proposal is to set continuous and straight diversion dikes or quays basically along a main stream direction of ebb and flow in a sea area where reverse current is given a priority so as to form the channel-shaped deep water tidal channel in a shape of 'horn shaped mouth gates at two ends and a long and narrow passage in the middle', wherein the channel forms a basin for shipping or a deep water channel; and the diversion dikes or the quays at the two sides of the channel form a port deep water coastline. The technical effects of the channel-shaped deep water tidal channel are as follows: the 'two-way water control effect' allows the overall sediment transport capacity of flow to be not less than the water sediment concentration; and the water depth of the basin for shipping and a sea-route water area after basic construction deepening is maintained for a long term; and the formed channel-shaped tidal channel has the advantages of straight coastline, long coastline, wide water area breadth, fast channel water area flow rate, deep water depth, small back silting, and good flow pattern.
