A filter device may include a filter housing, a ring filter element arranged within the filter housing, a tubular dome engaging in an interior of the ring filter element, and a valve arranged in a clean channel. The ring filter element may include a lower end disc and a pin. The ring filter element may engage a first channel via the pin. The tubular dome may have a guiding contour which may interact with a guiding element of the ring filter element. The guiding contour may include an axial groove. The pin may be introducible into the first channel when the guiding element enters the axial groove. The guiding element and the valve may be structured and arranged such that the guiding element interacts with a valve body of the valve and transfers the valve body into an opening position when the guiding element is slid into the axial groove.

An exchangeable filter system is provided with an exchangeable filter module that has at least one fluid inlet, at least one fluid outlet, and a fluid path connecting the at least one fluid inlet and the at least one fluid outlet with each other. The exchangeable filter module is provided with at least one filter element for filtering a fluid. A flange element and a counter flange element are provided. The flange element is provided to releasably engage the exchangeable filter module and to releasably engage the counter flange element. A valve device is arranged in the flange element. The valve device blocks the fluid path when the flange element is in engagement with the exchangeable filter module and is disengaged from the counter flange element. An internal combustion engine is provided with such an exchangeable filter system to filter fuel, lubricant or urea.

According to one aspect of the disclosure, a bulk material handling method includes receiving bulk material on a first level of a system at receiving stations equipped with dust control filtration equipment, pneumatically conveying the bulk material up to a third level into bulk material storage hoppers, storing the bulk material, dispensing the stored bulk material to a bulk material transporter on the first level, including dosing the stored bulk material to an interior of a bulk material dosing hopper to create a bulk material dose, docking the dosing hopper with the transporter via a docking apparatus, and releasing the dose into the interior of the transporter, through a reduced pressure region in an internal volume of the docking apparatus. Other disclosed aspects include a related system, subsystems, and apparatuses.

A disposable dental waste filter device has a body having a receiving end, and a separable cap having a tip end, the body for receiving and capturing therein amalgam that enters into the body through the tip end and the separable cap. A disposable dental waste filter device also has a body having a receiving end, a central lumen for receiving and capturing amalgam, a filter, and a circular leg portion having an exterior channel, and a separable cap having a tip end, a circular outer rim having a circular end ridge portion with the ridge portion adapted to be inserted into the exterior channel of the body for a snap fit engagement between the cap and the body, the body for receiving and capturing therein amalgam that enters into the body through the tip end and the separable cap.

A non-slippery outsole article comprises a first sole and a plurality of slip-resistant blocks. The first sole has two opposite sections, a top section in contact with a shoe body and a bottom section in contact with ground. The slip-resistant blocks are mounted in partition at the bottom section of the first sole, a plurality of protrusions being mounted on the top section of the first sole. The slip-resistant blocks are made of rubber and have a rough surface capable of slip resistance.

A valve member having a first flow path and a second flow path, and configured to control both flow paths through a filter assembly. The valve member allows control of the two flow streams in a compact space compared to traditional valves. The valve member may require less space to operate due to its compact nature as compared to traditional external valves with multiple handles that each require space to rotate. The valve member may also be used to easily shut-off flow to a filter of a filter assembly without limiting use of another filtration assembly in the same filtration system. Alternatively, the valve member may shut off flow to a corresponding filter of a stand-alone filter assembly that is not connected to another filter assembly. Also, the valve member allows less expensive and more lightweight filtration systems.

A water filtration apparatus comprises a housing having a housing outlet and a housing inlet, the housing outlet configured to allow filtered water to exit therefrom, the housing inlet includes a valve stem, where the housing has latch arms disposed adjacent to the valve stem. At least one filter is disposed in the interior portion of the housing, and the at least one filter is in fluid communication with the housing outlet and the housing inlet. A valve assembly includes a valve body releasably coupled with the valve stem, where the valve body has a faucet interface component, and the valve body configured to fluidly couple with a faucet via the faucet interface component. The valve assembly has a valve body release coupled with the valve body, and the valve body release is slidable relative to the valve body and the one or more latch arms.

A chemical solution supply system including: a first tank that stores a first chemical solution; a first pipe that is connected to the first tank and conveys the first chemical solution; a first filter unit that is connected to the first pipe and has a first filter through which the first chemical solution is filtered; a first valve that is provided in the first pipe between the first tank and the first filter unit; a second tank that stores a second chemical solution; and a second pipe that is connected to the second tank and the first pipe between the first filter unit and the first valve.
