Patent number: 5699940Abstract: A device to empty fluid from a sealed pressure container by use of pressurized air, and thereafter to place the container under vacuum. The device has a sleeve portion which defines an interior chamber. A ring portion with a hole extends into the interior chamber and forms a seating surface. A slidable seat with an aperture is located in the interior chamber below the ring portion and is sized to loosely fit in the interior chamber and seat on the ring portion. An upper cap with an air channel is located at the upper end of the sleeve and a lower cap with an air channel is placed at the lower end of the sleeve portion. A spring placed in the interior chamber between the lower cap and the slidable seat biases the slidable seat into contact with the ring portion. A floatable ball is placed above the slidable seat and is adapted to fluid tightly seat on and seal off its aperture. The floatable ball is sized to freely pass through the hole in the ring portion. A vacuum generator is also provided.Type: GrantFiled: July 8, 1996Date of Patent: December 23, 1997Assignee: C.H. & I. Technologies, Inc.Inventor: James E. Clark, II

Patent number: 5570813Abstract: A viscous material delivery and management system for delivery of a particular viscous material to a viscous material utilizing destination. The system has a sealed container for containment of a particular viscous material, a source of inert gas in gaseous communication with the sealed container, and a viscous material conduit in communication with the sealed container for delivery of the particular viscous material. The inert gas provides the motive force to move the particular viscous fluid from the sealed container to the viscous material utilizing destination.Type: GrantFiled: May 22, 1995Date of Patent: November 5, 1996Assignee: C.H. & I.

Patent number: 5558140Abstract: A fluid container draining device for draining fluid from a fluid container, an oil filter, in a controlled manner. The fluid container draining device has a threaded screw with a sharpened tip and a channel communicating between an opening at a forward end of the screw and a rear region of the threaded screw. When the screw is turned it will penetrate the wall of the fluid container and enter the fluid containing cavity of the fluid container. The threaded screw has a radially extending abutment surface to provide fluid tight sealing between the screw and the fluid container's walls to prevent fluid leakage. A fluid valve is positioned at the rear region of the screw to provide fluid flow control between the interior of the fluid container and outside the fluid container. The fluid valve is provided with a fitting for connection to a suction line to thereby permit fluid to be evacuated from the fluid container.Type: GrantFiled: September 2, 1994Date of Patent: September 24, 1996Assignee: Clark Technology Systems, Inc.Inventor: James E.

Patent number: 5546979Abstract: A fluid container draining device for draining fluid from a fluid container, such as an oil filter, in a controlled manner. It has a front threaded screw with a sharpened drill tip. It has an internal channel communicating between an opening at the forward end of the screw and a rear region of the threaded screw. A fluid valve is positioned at the rear region of the screw in fluid connection with the channel. The fluid valve provides fluid flow control between the interior of the fluid container and the outside of the fluid container. The fluid valve has an internally threaded front region which screws into the externally threaded rear region of the screw, and an externally threaded rear region, onto which a fluid evacuation line is to be attached. A turning portion for turning the device into the wall of the container is located on the device.Type: GrantFiled: February 7, 1995Date of Patent: August 20, 1996Assignee: Clark Technology Systems, Inc.Inventors: James E.

Patent number: 5546986Abstract: A leakproof dual action valve which is operated by its relative state of engagement and disengagement to a complementary, mating spring-actuated valve connected to a fluid supply. The dual action valve has a sleeve member, a piston carrier portion, a piston body, and a valve. As the sleeve member of the dual action valve is screwed onto the mating spring actuated valve, the piston body simultaneously pushes open both the dual action valve and the spring actuated valve. When the sleeve member is unscrewed from the mating spring actuated valve, both valves close, thereby preventing and leakage of fluid. The dual action valve is adapted to connect to a vacuum hose, which will evacuate any fluid from the fluid supply.Type: GrantFiled: February 7, 1995Date of Patent: August 20, 1996Assignee: Clark Technology Systems, Inc.Inventors: James E. Clark, II, Poul Van Santen

Patent number: 5437202Abstract: A fluid sampling device for use in obtaining a precise volume of fluid to be sampled from a sealed vessel equipped with a hydraulic fitting to which the fluid sampling device is connectable. The device has a fluid sampling float chamber with an internally sealable top opening which opens into a bottom end of an air channel and a bottom opening which opens into a top end of a fluid channel. A floating ball is located in said fluid sampling float chamber and is sized to be sealingly sealable at the top opening. A vacuum generating means relying on air flow through a venturi to draw air out of the fluid sampling chamber through the air channel is located above the top opening of the float chamber. An air valve is located downstream of the venturi for controlling the direction of air flow though the venturi. A hydraulic coupler is located at a bottom end of the fluid channel which when connected to the hydraulic fitting on the sealed vessel opens, but when disconnected from the fitting closes.Type: GrantFiled: October 18, 1994Date of Patent: August 1, 1995Assignee: Clark Technology Systems, Inc.Inventor: James E.

Patent number: 5435468Abstract: A reusable viscous material dispensing system. The system has a sealed pressure cylinder with a rounded upper region with an inert gas inlet, and a rounded bottom region with a viscous material ingress and egress opening. A pressurizing boat is contained in the cylinder. The pressurizing boat has a lower, hull portion which is weighted with ballast, and an upper portion. The lower, hull portion and upper portion join along a circular interface region. The diameter of the circular interface region is smaller than the inner diameter of the cylinder. The boat floats in the cylinder filled with viscous materials, such as thick lubricating greases. The viscous material forms a gaseous pressure seal between the interface region of the boat and inside of the pressure cylinder. Fins extend radially outwardly from the interface region of the pressurizing boat. These fins prevent the interface region from scraping viscous materials off the sidewalls of the pressure cylinder.Type: GrantFiled: October 31, 1994Date of Patent: July 25, 1995Assignee: Clark Technology Systems, Inc.Inventor: James E.
