  • Patent number: 8047224
    Abstract: The present invention is for a cartridge insert valve to limit excess flow through a pipe which is part of a piping system. The cartridge insert valve includes a cylindrical housing and an inlet cap with an inlet opening defined therein. The inlet cap is positioned on a cylindrical housing first end. The cartridge insert valve also includes a seat cap with an orifice defined therein. The seat cap is positioned on a cylindrical housing second end opposite the cylindrical housing first end. The cartridge insert valve is located in the pipe such that a fluid flowing through the pipe normally enters the inlet cap, flows through the cylindrical housing and exits the seat cap. The cartridge insert valve also includes a piston assembly that shuts off flow through the valve in response to an excess flow through the valve.

  • Patent number: 7900395
    Abstract: The invention is for landscape edging with improved mulch containment and improved drainage. The landscape edging has a substantially vertical planar surface adjacent to a substantially horizontal surface. The vertical planar surface and the horizontal planar surface are adhered to a sidewalk or pavement that borders a flower bed or garden. A riser extends upward from a first end of the horizontal surface. A lip surface extends from the riser in a direction away from the horizontal planar surface. A curved canopy surface extends from the lip, back over the lip and the horizontal surface, until it intersects with a flower bed wall. The flower bed wall it is a curved surface that extends between a second end of the horizontal planar surface and the canopy surface. The flower bed wall has orifices disposed therein to allow water from the flower bed to enter the landscape edging.

  • Patent number: 7537017
    Abstract: The invention is a shoulder support for a crutch having a pair of upper tubes that slide inside a pair of lower tubes. The shoulder support includes tube caps that are supported at a top of the upper tubes and a channel section positioned between the tube caps and attached to the tube caps by a bolt. A shoulder spring is bent into a bow-tie shape with two loops and a narrow portion. A crutch user positions his underarm atop the shoulder spring to support his weight, and the shoulder spring loops deflect outwardly when a user bears his weight on the crutch. The shoulder support includes a resilient shoulder pad that covers the shoulder spring to protect skin beneath arms of the user from scraping and chafing. Two rivets secure the narrow portion of the shoulder spring to the channel section at a top of the channel section.

  • Patent number: 7380565
    Abstract: The present invention is for a spill prevention system to prevent fuel spills from a connecting line connecting duel fuel tanks on a truck when the connecting line is severed or detached from one of the reducer fittings to which it is attached. The connecting line provides pressure communication between the fuel tanks so that fuel flows from one tank to the other whenever there is an unequal pressure acting on the fuel, which occurs whenever one tank has more fuel in it than the other. The connecting line connects to the reducer fitting located on each fuel tank. A safety valve is immersed in the fuel in each tank and connected to the reducer fittings. Each safety valve is configured to shut off flow to the connecting line when the connecting line is severed or detached from the one of the reducer fittings.

  • Patent number: 7258131
    Abstract: The invention is for a safety valve for a piping system. The safety valve has a cylindrical housing, a piston assembly with two disc-shaped pistons, each piston having at least one orifice defined therein, a shaft connecting the pistons, a valve stem, and a stop attached to one end of the valve stem. The safety valve has a valve seat with an opening shaped and sized to receive the stop. The safety valve has a spring positioned in the housing against the piston assembly so that the spring exerts a spring force on the second piston in a direction opposite the direction of fluid flow. When fluid forces acting on the piston assembly exceed a spring force acting on the piston assembly, the piston assembly moves in the direction of flow until the stop engages the valve seat and shuts off flow through the safety valve.

  • Patent number: 6988462
    Abstract: The invention is for a memory assist device with an indicia field to indicate a number. The memory assist device includes at least two filaments extending between internal walls of the memory assist device to form an indicia field. The memory assist device also includes clips selectively clamped on the filaments to indicate the number. In one embodiment, the memory assist device has a loop portion for attachment to a key chain when using the memory assist device to indicate a floor on which a user has parked his car in a parking garage. In other embodiments, the memory assist device has a first numerical label to associate a numerical expression with a particular clip. In still other embodiments, the memory assist device has a second numerical label to indicate the position of the clips within the indicia field.
