  • Patent number: 6803022
    Abstract: A device and method for separating heavier and lighter fractions of a fluid sample. The device includes a plurality of constituents comprising a container and a composite element in the container. The composite element is a separator comprising a deformable bellows, a ballast mounted to the lower end of the bellows, and a float is engageable with an upper end of the bellows. A fluid sample is delivered to the container and the device is subjected to centrifugation whereby the centrifugal load causes the ballast to move toward the bottom of the tube and causes an elongation and narrowing of the bellows. The separator then moves down the tube and stabilizes in a position between the separated phases of the fluid sample. Termination of the centrifugal load enables the bellows to return to its original condition in sealing engagement with the walls of the tube.

  • Patent number: 6797161
    Abstract: A chamber having an inlet for receiving polluted storm-water runoff and an outlet for the storm water to flow out. Within the chamber are a screen, one or more baffles, a collection reservoir, and a pivotal filter. The screen is elevated for separating and suspending miscellaneous debris such as vegetative matter, paper, and plastic. The baffles increase storm-water residence time to encourage settling of particulate matter such as sand and grit. The collection reservoir has an adjustable weir for skimming off floating matter such as motor oil, other hydrocarbons, and detergents. And the pivotal filter catches clay during typical storm flows and pivots out of the way during higher flows. In addition, a method for maintaining the pollution trap includes removing the screen for cleaning, suctioning out the particulate matter and oil, and replacing the pivotal filter member.

  • Patent number: 6685829
    Abstract: The invention relates to a fluid filter, such as an oil filter for a combustion engine. The inventive filter comprises an exchangeable filter inset which is provided with a ring-shaped cross-section that encompasses an inner chamber. The outlet for the purified fluid is joined to the inner chamber. The inventive filter also comprises a discharge line for emptying the filter during a filter change. A central discharge dome is provided which extends into the inner chamber. Said dome, together with the filter inset is mounted in such a way as to be axially displaced between a first closing position which closes the discharge line and a second release position which releases the discharge line. According to the invention, the discharge dome is fixed to the housing and is pushed into the release position thereof when said dome is impinged upon with a spring.

  • Publication number: 20030178351
    Abstract: A two-stage, retrofit filter is adapted for use with an electrical discharge machine (EDM) includes nested inner and outer filtering elements that may be placed as a unit in the same tank and over the apertured standpipe used for a one-stage filter, such that the fluid to be filtered now flows through each of the multiple filter elements. The retrofit EDM filter may be configured for flow in either direction, though the usual arrangement is one whereby the fluid being filtered flows up through the bottom of the tank, out the apertured standpipe, and into the inner filter element. Preferably, the filter elements are cylindrical, pleated elements composed of a technical grade filter paper. In the preferred embodiment, a pressure-operated release valve is provided in conjunction with the inner filter, such that when a predetermined pressure is reached due to the entrapment of contaminants by the inner filter, the valve opens to allow the fluid to be filtered to flow through the outer filter.

  • Patent number: 6613221
    Abstract: A sieve filter for fluid lines, especially for hydraulic pressure lines (2) in internal combustion engines which is formed of a hollow cylindrical main body (3) with a fluid inlet (4) and a fluid outlet (5), and of a fine mesh filter element (6) for through flow by fluid which has a bypass function when the filter element (6) is stopped up or filtering highly viscous fluid. The sieve filter (1) is biased by a spring element (7), and is insertable together with the spring element (7), between two axially spaced opposing surfaces (8, 9) inside the pressure line (2) such that its fluid inlet (4) and the spring element (7) are prestressed against the opposing surfaces (8, 9), whereby the main body (3) of the sieve filter (1) closes a bypass fluid channel passing the filter element (6) which is clearable through an axial displacement of the main body (3) against the force of the spring element (7) resulting from the rise of fluid pressure on the filter element.

  • Patent number: 6478954
    Abstract: A floating debris removal system has a bypass or overflow grate that is hinged at the top and positioned to swing downstream under certain conditions. The grate is fastened with a shear ring that will break when sufficient force is generated against the grate by the flow of overflow water and debris through the system. A plow-shaped member pivots off upwardly as flow increases. The member has a plow-shaped blade that spreads the flow across the inlet of the trap of the system to reduce the velocity of the flow. The shape and weight of the blade are selected for optimal function under a range of water levels and flow velocities, and can be altered to perform best for different installations. Debris pits are provided before or after the traps of the system to collect small suspended debris that is not removed by the traps. The pits are sized and configured to slow the velocity of the flow of that the suspended debris settles into the pits.
