  • Patent number: 10112134
    Abstract: An apparatus and method for filtering a liquid utilize a filter apparatus including a bypass filter, a full flow filter, and a flow balancing element for dividing a total inlet flow of fluid to the filter apparatus into a bypass portion, passing through the bypass filter, and a full flow portion, passing through the full flow filter. The bypass filter has a lower filtering efficiency than the full flow filter element, so that a venturi tube is not required for causing the bypass portion to pass through the bypass filter. The flow balancing element divides the flow into a desired bypass portion and a desired full flow portion, at a predetermined operating temperature. Below the operating temperature, the bypass portion increases and the full flow portion decreases, the bypass portion becoming greater than the full flow portion at a second predetermined temperature below the operating temperature.

  • Patent number: 9884778
    Abstract: The present disclosure relates to a filter, which comprises a housing, a protective bushing, a magnetic bar and a filter screen. The protective bushing, the magnetic bar and the filter screen are disposed in the housing. The protective bushing comprises a cavity and a channel. The channel is disposed along the axial direction of the cavity. The magnetic bar inside the filter adsorbs metal impurities in water in the channel. The shape of the channel increases the length of the flow path of the water so that the metal impurities in the water can be guaranteed to be sufficiently adsorbed by the magnetic bar. The filter screen filters out non-metal impurities in the water. An exhaust valve provided at the top of the protective bushing balances air pressure inside the filter and outside the filter, such that the water can flow out and in smoothly.

  • Patent number: 9884273
    Abstract: A fluid filter assembly is provided comprising a filter can, a filter cover assembly, and an interior filtering assembly. The filter cover assembly comprises an outer cover plate and an inner mounting plate. The outer cover plate of the filter cover assembly comprises a drawn-down portion that descends toward the interior volume of the fluid filter assembly and exhibits a metallic grain structure that is stretched relative to the metallic grain structure of the inner and outer circumferential mating portions of the outer cover plate. In one embodiment, the inner mounting plate is secured to a backside of the outer cover plate such that, upon rotational engagement of the internal threads of the inner mounting plate with a threaded fluid port, the inner mounting plate rotates with the filter can and the outer cover plate to advance in an axial engagement direction and forcibly urge the outer cover plate in the axial engagement direction from the backside of the outer cover plate.

  • Patent number: 9809969
    Abstract: A system designed to control and filter runoff water in storm drains is presented. Drain water frequently carries trash, organic matter, suspended solids, hydrocarbons, metals, nutrients and bacteria collected from streets and parking lots into a storm drain inlet, which enters storm water drain pipe systems. The present invention supplies a series of baffle boxes inserted in the drain water stream with a final box possessing an upflow filter comprising filtration media and filter cartridges. The system can also support a storm flow bypass that directs high-flow storm runoff water directly to the outlet to protect the filter system.

  • Patent number: 9757664
    Abstract: The invention provides systems and methods for the automation of the extraction of a liquid substance from a material. The disclosed systems include multiple tanks and valves under computer control providing for the safe transport of a solvent through the material under computer control. Solvent transport is accomplished by heating and/or cooling selected tanks or vessels to cause the solvent to evaporate or condense as desired. Tank and/or solvent heating and cooling is controlled automatically. Thus, in all embodiments the use of external pumps can be avoided.

  • Patent number: 9700818
    Abstract: A filter apparatus and filter element therefore are provided. The filter apparatus includes a filter head including an inlet port, a main flow outlet port and a drain flow outlet port. The filter element includes a ring of filter media defining an internal cavity. The filter element defines a main flow passage and a drain flow passage through the internal cavity. Each flow passage has an inlet on a clean side of the filter media directly fluidly communicating with the internal cavity. The main flow passage is fluidly coupled to the main flow outlet port. The drain flow passage (or air bleed passage) is fluidly coupled to the drain flow outlet port and includes (i) a restriction 154 sized large enough to allow air flow and small enough to prevent substantial liquid flow and (ii) a check valve 912 limiting flow to a single direction. The filter media separates the inlet port from the main flow and drain flow outlet ports.
