  • Patent number: 6976807
    Abstract: A portable breakwater system for use in a body of water includes first and second support members adapted to be positioned on the floor of the body of water and a curtain attached between the first and second support members. The first and second support members allow the curtain to freely rise in response to a wave in the body of water so as to attenuate the wave. Each support member includes a base plate and a frame assembly extending upwardly from the base plate. The base plates can be anchored to the water floor with one or more weights. The frame assemblies include pivoting or telescoping sections that permit the curtain to rise in response to a wave. Alternatively, the curtain can be attached to pre-existing underwater structure, such as the support members of a dock located in the body of water. In this case, the curtain is attached to the support members via attachment sleeves that are slidingly mounted on the support members.

  • Patent number: 6925663
    Abstract: A crib device is provided for raising and lowering the dropside of a slatted crib. The dropsides are fitted with side rails attached to the outer slats. The side rails are channeled to receive a rod. The side rails fit within corner legs which are slotted to receive the side rails. The corner legs are also channeled to receive a rod. When the side rails are fitted within the corner legs, a slide rod is positioned through the respective channels. A latching mechanism is used to lock the dropside in place via a latching rod and latch rod recesses, which are located on the corner legs. When the latching mechanism is activated the dropside moves vertically along the slide rod with reduced risk of injury to both the user of the crib and the occupant of the crib as the outer slats block unwanted access to the slotted region of the corner legs.

  • Patent number: 6869255
    Abstract: A structural pile assembly includes a driven pile and pressurized grout contained beneath the pile so as to exert an upward force on the pile. An enclosure, such as a bladder or bellows, is filled with grout from a reservoir via a conduit which preferably extends axially along the length of the pile and is left in place after the grout hardens. A pressure gauge measures the pressure of the grout within the enclosure, permitting the direct measurement of end bearing and side bearing capacities of the resulting pile assembly. The load bearing capacity of the pile is enhanced by the pressurized grout, and is preferably at least twice the end bearing capacity of an unpressurized pile.

  • Patent number: 6854935
    Abstract: A method of reducing ground disturbance during freeze-thaw cycles. The steps include excavating soil from an area affected by ground disturbance due to subsurface flow and subsequent freezing of water. A subsurface layer of thermal insulation is then laid over the affected area, thereby thermally insulating the affected area from freezing. The subsurface layer of thermal insulation has a top surface and a bottom surface. A subsurface layer of wick material capable of drawing water away from the affected area by capillary action is also laid parallel to one of the top surface or the bottom surface of the subsurface layer of thermal insulation positioned in a path of the subsurface flow of water.
