20100074686 | Structure forming a breakwater and capable of ice free, year round operation - A structure for use in a body of water has at least one level that includes a boat lift, a narrow dock, or a larger entertainment area, or combinations of these items on multi-level structures (e.g. a boat lift on a first level and an entertainment area on a second level). The structure can be towed to or from a body of water independently of other structures. The structure includes a buoyancy system, e.g. at least one ballast tank or inflatable bladder, for allowing the structure to float in a buoyant state or to sink in a non-buoyant state into engagement with a bottom of the body of water. One or more structures such as these can be assembled to form an artificial breakwater by placing a wall or skirt on the windward side(s) thereof with each wall or skirt extending from below to significantly above the waterline. This forms a calmer area of water on the leeward side(s) thereof. In addition, an opposing wall or skirt can be placed on opposite sides of the structures to form a bounded chamber beneath the structure. A water recirculating device is used to pull up warmer water from near the bottom of the body of water and to discharge this warmer water into the bounded chamber and/or a water heating device is provided in the bounded chamber. This helps keep the structure sufficiently ice free to permit year round use if so desired even in northern climates. | 03-25-2010 |
20100261587 | SELECTORIZED DUMBBELL HAVING A SELECTOR COMPRISING A PIN HAVING FORK-SHAPED CONNECTING PRONG(S) - A selectorized dumbbell has a handle that can be inserted into a gap between stacks of nested left and right weight plates. A selector determines how many left weight plates are coupled to the left end of the handle and how many right weight plates are coupled to the right end of the handle.
