  • Patent number: 12364943
    Abstract: A filter material for use in fuel-water separation has a particle filtration layer and a coalescing layer downstream of, and coupled to, the particle filtration layer. The particle filtration layer is substantially constructed of binder fibers and media fibers. The coalescing layer has at least 70% glass fibers by weight. As another example, a filter material for liquid fuels has a particle filtration layer and a coalescing layer downstream of the particle filtration layer. The particle filtration layer has binder fibers and media fibers and is substantially free of meltblown materials. The ratio of air permeability of the particle filtration layer to air permeability of the coalescing layer ranges from about 3:1 to about 15:1.

  • Patent number: 12318713
    Abstract: A filter element has an upstream and downstream side. A filter media assembly of the filter element has an upstream side and a downstream side and has a first filter media layer and a second filter media layer that is adjacent to the first media layer. A substantial portion of the first layer and second layer are uncoupled, and at least one of the first media layer and second media layer comprises binder fiber. The second media layer has a mean flow pore size equal to or smaller than the first media layer. A support layer system is adjacent to the downstream side of the filter media assembly, and a first wire mesh layer is adjacent to the support layer system. At least the first media layer, second media layer, support layer system, and first wire mesh cooperatively define pleats at a pleat packing density of greater than 125%.

  • Publication number: 20240424081
    Abstract: Influenza vaccines are administered using solid-biodegradable microneedles. The microneedles are fabricated from the influenza vaccine in combination with solid excipient(s) and, after penetrating the skin, they dissolve in situ and release the vaccine to the immune system. The influenza vaccine is (i) a purified influenza virus surface antigen vaccine, rather than a live vaccine or a whole-virus or split inactivated vaccine (ii) an influenza vaccine prepared from viruses grown in cell culture, not eggs, (iii) a monovalent influenza vaccine e.g. for immunising against a pandemic strain, (iv) a bivalent vaccine, (v) a tetravalent or >valent vaccine, (vi) a mercury-free vaccine, or (vii) a gelatin free vaccine.

  • Patent number: 12172111
    Abstract: Thermoplastic bicomponent binder fiber can be combined with other media, fibers and other filtration components to form a thermally bonded filtration media. The filtration media can be used in filter units, such as breather caps. Such filter units can be placed in the stream of a mobile fluid and can remove a particulate and/or fluid mist load from the mobile stream. The unique combination of media fiber, bicomponent binder fiber and other filtration additives and components provide a filtration media having unique properties in filtration applications.

  • Publication number: 20240229312
    Abstract: A thermally bonded filtration media that can be used in high temperature conditions in the absence of any loss of fiber through thermal effects or mechanical impact on the fiber components is disclosed. The filter media can be manufactured and used in a filter unit or structure, can be placed in a stream of removable fluid, and can remove a particulate load from the mobile stream at an increased temperature range. The combination of bi-component fiber, other filter media fiber, and other filtration additives provides an improved filtration media having unique properties in high temperature, high performance applications.

  • Publication number: 20240206743
    Abstract: A monitoring system comprises sensors adapted to be worn by a user, and, a processor linked with the sensor. The processor receives sensor data and processes this data to determine user posture data including data indicative of vertical distance between level of the user's heart and ankle. Based on the posture data together with a value for degree of user chronic venous insufficiency and/or blood density, generate an estimate of user static venous pressure while the user is static, without calf muscle pump activity. The processor also processes the sensor data to determine if there is calf muscle pump activity, and generates an estimate of user active venous pressure according to the static venous pressure estimate, rate of calf muscle activity, and a value for degree of user chronic venous insufficiency. The processor may generate the venous pressure estimate in real time, and may control an NMES device accordingly.

  • Publication number: 20230226475
    Abstract: A filter and filter media configured and arranged for placement in a fuel stream is disclosed. The filter and filter media allow for filtering of liquid fuels, such as diesel fuel. In certain embodiments the filter media includes a media fiber (such as glass) and a binder fiber (such as bicomponent) that combine to create a media structure having low solidity and relatively low compressibility, and which contain a pore structure that avoids premature fouling of the filter by fuel degradation products.

  • Patent number: 11654271
    Abstract: Disclosed is a system for vascular access, where the system allows for transitions between retrograde and antegrade access without generation of multiple access sites and without inducing extensive vascular damage. In embodiments, the system can include a vascular access portion including a body with a first lumen for preferentially providing access in a retrograde direction into a vessel, and a second lumen for preferentially providing access in an antegrade direction into the vessel. The body can be transitioned (e.g., by way of expansion, contraction, or other deformation mode) between a retrograde delivery mode and an antegrade delivery mode.
