  • Patent number: 11563222
    Abstract: An all mechanically controlled, non-venting pressure control system for liquid hydrogen and liquid oxygen cryogenic tanks that requires no electrical control while managing disparate, non-stoichiometric reactant boil-off rates is provided. The pressure control system allows for the passive and repeatable stoichiometric consumption of hydrogen and oxygen boil-off from cryogenic tanks to form liquid water, while preventing the liquid hydrogen and liquid oxygen cryogenic tanks from overpressurizing and venting to the external environment. More particularly, in response to an overpressure condition in a first reactant reservoir, a backpressure regulator is opened, providing the overpressure first reactant to a fuel cell or other consumer, and providing a pilot signal to open a supply line from a second reactant reservoir to the consumer. Whether the second reactant is supplied from the second reactant reservoir as gas or a liquid is determined based on the pressure within the second reactant reservoir.

  • Patent number: 11547961
    Abstract: A filter element has a first follower element with a first traction surface and a second follower element with a second traction surface provided for interacting with first and second mating surfaces of the filter housing, respectively. The first and second traction surfaces interact with the first and second mating surfaces to pull out the filter element from the filter housing. The first and second traction surfaces are spaced apart from each other along a longitudinal axis of the filter element and project radially into the interior of the filter element. At least one of the first and second follower elements has a stop surface adjoining circumferentially the respective traction surface. In a position of use, the stop surface interacts with a counter stop surface of the filter housing to form an at least unidirectional rotational degree of freedom blocking about the longitudinal axis relative to the filter housing.

    Abstract: A filter cartridge for a whole house water filter includes a cylindrical, or tubular, filter media coupled to a mixer tank with improved high flow mixing features. The mixer tank includes a bowl in which a flow diverter, a flow guide with angled fins and a filter media are provided. The flow diverter has a concave portion, i.e., a mushroom-shaped portion, the interior of which is in fluid connection with a central passage through which filtered water flows. In operation, the filtered water flows through the central passage and is deflected by the concave interior of the flow diverter down through the angled fins of the flow guide. The filtered water then passes out through an outlet. The mixer tank stirs the filter media and water mix to increase the kinetics of the mixing process.

  • Patent number: 11434149
    Abstract: The devices, systems, and methods of the present disclosure are generally directed to using an increase in gas pressure (e.g., through an increase in heat) to move an actuator that at least partially defines a volume containing a feed fluid in fluid communication with a membrane. As the increase in gas pressure moves the actuator, pressure on the feed fluid in the volume may increase beyond a threshold pressure sufficient to move the feed fluid through the membrane. Movement of the feed fluid through the membrane may reduce a volumetric concentration of one or more components of the feed fluid to form a permeate. For example, the increase in pressure may drive the actuator to increase pressure on salt-water in the volume and, ultimately, move the salt-water through the membrane to form the permeate as part of a reverse osmosis process achieved without the use of a mechanical pump.

  • Patent number: 11052336
    Abstract: A filter device allows avoiding liquid and dust before filtration to flow out to a tank during replacement of a filter element. A case includes a first tubular portion and a second tubular portion positioned with a lower side of the first tubular portion. The second tubular portion has a diameter smaller than that of the first tubular portion. In a state where the filter element is provided inside the case, a tubular portion of the filter element abuts on the second tubular portion. A part abutting on the second tubular portion of the tubular portion is absent of a hole. A part without abutment on the second tubular portion of the tubular portion has a plurality of holes.

  • Patent number: 10994231
    Abstract: A filter includes a filter assembly deployed within a pressure vessel. The filter includes a series of filter configurations arranged along a central flow path connected to an outlet. Each filter configuration has filter screens overlying at least one filtrate channel which directs filtered fluid to the central flow path, A partition is deployed within the pressure vessel so as to subdivide the pressure vessel into a first filter chamber and a second filter chamber, each containing a number of the filter assemblies. A flow diverter is deployed in the central flow path for diverting a flow of filtered liquid passing along the central flow path from the first filter chamber so as to flow outwards from the central flow path to undergo a second filtering in the second filter chamber. Also disclosed is an outlet flow throttling arrangement to avoid overload of a backwash cleaning system.

  • Patent number: 10940409
    Abstract: Cartridge components are configured to trap the upper end of a concave housing portion to define an enclosure surrounding a filter element. A disclosed embodiment includes a concave metal housing portion and plastic cartridge components, but other materials may be employed. An upper end cap spans the open end of the housing portion and defines at least one fluid flow aperture. A retainer surrounds the housing portion and is secured to the first component, with engagement features on the housing portion trapped between the upper end cap and retainer. The upper end cap and retainer may be secured to each other by spin welding, threads, adhesive or other suitable means. The outside circumference of one or both of the upper end cap and retainer may be provided with lugs, threads, bosses or other features to interface with complimentary features on the head for securing the cartridge to a head.

  • Patent number: 10926202
    Abstract: A filter device has a filter element (1) received in a filter housing of at least two interconnectable housing parts (17, 19). The filter element (1) can be fixed to a housing part (19) in a removable manner by one screw connection (32, 33). An additional screw connection (17, 41) is provided for connecting the housing parts (17, 19). To transmit a torque between threaded elements (33) of the one screw connection (32, 33) and of the additional screw connection (41), the threaded elements are rotatable relative to each other. A coupling device (43, 46, 61) is added that allows an additional rotational movement of the threaded element (17) of the additional screw connection (41) when the threaded element (33) of the one screw connection (32, 33) reaches the fixed rotational state.

  • Patent number: 10926205
    Abstract: A filter assembly has a one-piece cast metal pressure vessel with an inlet port communicating only with an inlet chamber and an integral offset bulkhead forming a separate filtrate chamber on the opposite side of the bulkhead having an upper exit port and lower exit port on opposite sides of the filtrate chamber. A filter assembly is disposed through an aperture in the bulkhead with the filter inlet side communicating only with the inlet chamber and the filter outlet side communicating only with the filtrate chamber. An access opening is provided in the top of the pressure vessel with a lid for changing filters. A closure member attached over the lower exit port configures the assembly for simplex operation. Relocating the closure member to cover the upper exit port on a pair of the pressure vessels with filters therein readily configures the pair for attachment to opposite sides of a central diverter valve for duplex filtering operation without rework of either of the pair of pressure vessels.
