A no filter no run (NFNR) fluid filter and fluid filter assembly are provided. The NFNR fluid filter assembly includes a fluid filter, a filter head or filter housing, and a bypass flow path. The bypass flow path may be sealed off when a compliant filter is installed. When a non-compliant filter is installed (a filter without a bypass seal), fluid may flow to the bypass flow path.

A multi-bank cooking system includes multiple discrete cooking systems sharing common plumbing and integrated safety features. The multi-bank cooking system may include two or more rack-fryer systems, each with discrete frypots, operating mechanisms and cooking controllers. Each of the discrete cooking systems, may share a common plumbing system with integrated valves and controls receiving coordinated safety signals to facilitate safe and efficient operation of the system.

A reductant storage system for an internal combustion engine system includes a storage container having a bottom wall, a top wall opposite the bottom wall, an opening extending through the top wall, and a reservoir formed by a hollow interior of the storage container; a filter assembly; and a header assembly. The filter assembly extends through the opening and is configured to seal the opening and includes a filtering material. The header assembly extends through the opening and inside the filter assembly. The header assembly includes: (i) a first sensor configured to measure a quality of the reductant contained within the filter assembly and (ii) a second sensor configured to measure a level of the reductant contained within the filter assembly.

A liquid-submersible vacuum system includes a housing enclosing a filtration element and a water pump, and a power converter configured to couple to a standard AC power supply. The vacuum system further includes a vacuum-to-waste assembly detachably coupled to the housing for selectively conveying filtered fluid from the vacuum system to a remote location.

A system for TFF filtration of a feedstock includes a feed vessel containing a solution comprising a target biomolecule, a filter membrane for filtering the solution, a feed pump for moving the solution from the feed vessel to the filter membrane, a buffer vessel coupled to the feed vessel by a buffer supply line, and a diafiltration pump disposed in the buffer supply line for delivering a buffer solution to the feed vessel. A variable path-length instrument is coupled to the feed line for determining, in real time, a concentration of the target biomolecule in the solution. A controller is coupled to the variable path-length instrument, the feed pump, and the diafiltration pump to control operation of the system based on the received information.

The invention relates to a device for separating solid materials out of liquids or gases and for discharging solid material. The device comprises a pressurised container and at least one filter element, the at least one filter element being arranged in a flexible container which is arranged in the pressurised container and is sealed tightly relative thereto. The pressurised container comprises at least one outlet for discharging the solid material and the flexible container comprises at least one discharge connection, the discharge connection of the flexible container being guided through the outlet of the pressurised container and sealed tightly relative to the pressurised container. In this case the outlet and the discharge connection of the flexible container can be closed and sealed by means of a closure mechanism relative to the environment outside the flexible container and the pressurised container.

Methods and apparatuses for screening are provided. Embodiments include a screen basket apparatus for screening material, comprising a grid frame having a plurality of openings arranged in a lattice and a plurality of screening cartridge assemblies affixed to the grid frame to cover the respective openings of the grid frame. The screening cartridge assembly includes a case and a screen assembly fitted into the case, and may be affixed to a set of transversal member of the grid frame. The case may be an injection molded thermoplastic polyurethane or a thermoset polymer. The screening elements together form a generally continuous screening surface across an exterior portion of the grid frame.
