  • Patent number: 10857492
    Abstract: A filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with influent and effluent piping, such as within a refrigerator. The filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

  • Patent number: 10814054
    Abstract: An intermediate element for a medical extracorporeal fluid line designed to conduct a fluid, such as blood, has a main part extending between two connection parts. A flow channel passes continuously through the main part and the connection parts. The connection parts hydraulically connect the main body to a fluid line. On the periphery of the main part a receiving area is arranged, which is designed to receive a measurement value transmitter. An opening to the flow channel is defined in the receiving area and is sealed in a fluid-tight manner towards the receiving area by an elastic element. The measurement value transmitter is a gas sensor of a sensor device for measuring at least one gas contained in the fluid. The elastic element is a diffusion element, which is permeable to at least one gas. The diffusion element is bonded to an edge of the opening.

  • Patent number: 10618821
    Abstract: During the process of compressing air, atmospheric air along with water vapor and airborne contaminants are ingested into the air compressor. Many of these compressors utilize oil for lubrication, sealing and cooling. A compressor system utilizes drain valves to remove the condensate that accumulates in the system which are typically located on the compressor, moisture separators, coalescing filters, receivers, dryers, and drip legs. While the drain valves successfully remove the condensate, this condensate is now contaminated with lubricant. The compressor system also includes a filter for the removal of lubricant from the condensed water so that the water can be discharged to sewer. The filter is arranged to house a series of vertically stacked filter cartridges, each cartridge structured to pass fluid flow to the other cartridge. The housing and the cartridges each having registration surfaces to position the filter within the housing and discourage removal of the same.

  • Patent number: 10569266
    Abstract: An ion exchanger includes a housing and a cartridge. The housing has an inlet port, through which coolant flows in, and an outlet port, through which the coolant flows out. The cartridge is detachably attached to the housing. The cartridge is filled with ion-exchange resin. The ion exchanger is configured to remove ions from the coolant through ion exchange when the coolant flowing in the housing passes through the ion-exchange resin. The cartridge includes a bypass route that causes some of the coolant that has flowed into the housing to bypass the ion-exchange resin and flow to the outlet port.

  • Patent number: 10532300
    Abstract: A filtering device, a system including the filtering device, and methods of using the filtering device. The filtering device is configured to be arranged inside a fluid to be filtered and comprising at least one main filter and a filter holder supporting the main filter. The filtering device is configured to be moved inside the fluid, in such a way that when the filtering device is moved in a first movement direction, at least one part of the fluid passes through the main filter in a first filtering direction. The filtering device is configured in such a way as to prevent the fluid from passing through the main filter in a second filtering direction opposite to the first filtering direction when the filtering device is moved in a second movement direction opposite to the first movement direction.
