A locking-unlocking structure for stopping a lifting body, which is vertically lifted and falls through repetition of a pushing action, in a lifting state and for releasing a stopping state of the lifting body is provided. The locking-unlocking structure includes a lifting body, which is exactly lifted immediately upward, or falls without being fluctuated left and right and, to control lifting and falling operations of the lifting body, an actuation unit is mounted in the lifting body movably left and right, and an actuation guide unit, which guides an operation of the actuation unit, is fixedly mounted in a fixing body, and the lifting body is provided therein with a rotation groove allowing the actuation unit to be movable left and right when the lifting body is lifted or falls, and a rotation shaft rotatably coupled to the rotation groove is provided at one side of a lifting plate. The lifting plate is provided on a lower end of an opposite side thereof with a stop protrusion circulating a lifting line and a falling line branching left and right. The actuation guide unit, which is configured to guide an operation of the actuation unit, includes the lifting line having a rising curve line and the falling line having a falling curve line, the lifting line and the falling line branching left and right at a lower end of the actuation guide unit, to guide repeatedly circulating operations of the actuation unit. The actuation guide unit is provided at a central upper portion thereof with a stop groove interposed between the lifting line and the falling line to securely mount the stop protrusion in the stop groove.

A method and system for treating oilfield produced water is disclosed. The method includes passing oilfield produced water through a chain of filters, first filter configured to filter particles of a size larger than 10 m from the water, a second filter configured to filter remaining particles of a size larger than 2 m from the water and a third filter configured to filter remaining particles of a size larger than 0.5 m from the water and automatically cleaning at least one of the filters.

Disclosed is a capsule apparatus having a filter housing defining a filter chamber with a top cap having a plurality of ports extending substantially laterally from a top end of the top cap. The lateral and substantially uniform orientation of the ports facilitates connection to panel mount assemblies and improves filter maintenance processes. A transfer tube extending the length of the capsule allows the introduction of heated fluids from a top mounted inlet port to a bottom of the capsule chamber to allow or a substantially uniform heat gradient in the capsule filter chamber. A dispersion ring or dispersion plate may be secured to a distal end of the transfer tube to promote uniform dispersion of liquids and/or gases introduced into the capsule apparatus. An alternative shield secured in the housing defines a first chamber in fluid communication with an inlet and a second chamber wherein the two chambers are in fluid communication via an opening defined by a lower end of the shield and a bottom of the filter chamber. An alternative capsule apparatus has an outlet tube extending downwardly from a top mounted outlet port in fluid communication with an enclosed filter membrane secured below a column of loose filter media.

An apparatus having one or more filters positioned by a connection member. The connection member orientates one or more filters at a transverse angle relative to the horizontal to drain contaminants from the filter.

An upper endcap of a fuel filter cartridge includes a skirt, an axially extending pin surrounded by the skirt, and a plurality of ribs that define fluid flow channels leading to the pin. The pin is extendable through an axially facing fuel inlet opening at the upper end of a standpipe for actuating a valve to an open position allowing fuel to flow through the axially facing inlet opening and into the standpipe. The valve can include a hole that receives the pin therein to help stabilize the valve when the valve is actuated open.

The present disclosure relates to a system and regenerable molecular media for wastewater purification treatment and a preparation method thereof. The molecular filter media of the present invention are extremely high surface area filter granules and pellets that are either supplied loose or molded into blocks. The industry uses these for filtration in flow-through filter devices. The disclosed regenerants effectively break bonds and get the molecular filters ready for the next cycle of use.

The present invention provides a disposable ultra-filtration system comprising a disposable pipetting tip and a disposable ultra-filtration cartridge, wherein the cartridge includes a membrane filtration chamber and a dead-end channel. In use, a piston in the pipette pressurizes air within the channel; the pressurized air can subsequently move the piston and cause a reverse flow back through the membrane of the cartridge, unplugging the pores thereof. Also disclosed is an automated workstation incorporating the disposable ultra-filtration system, and a system comprising the automated workstation, useful for measuring the free therapeutic drug concentration and free hormone concentration in a sample.

A refrigerator includes a body configured to be equipped with a storage, a door configured to be hinge-engaged with the body to open or close the storage, a water supply line configured to respectively supply water provided from a water source to an ice maker placed in the storage and a dispenser placed outside the door. One or more filters are configured to be engaged with the water supply line, and one or more bypass valves for respective water tanks are configured to be engaged with the water supply line at a part which is lower than an engagement point of the one or more filters. The one or more water tanks are configured to be placed inside the door and to be detachably engaged with the bypass valve for water tank.

An apparatus for manufacturing filters and inserting the filters into single dose capsules for preparing beverages comprises a punching and forming device for punching material portions from a sheet material and forming the material portions to assume the form of a beaker-shaped filters, an insertion device arranged in a distance of the punching and forming device along a work flow direction for inserting the formed filters into the capsules, a first transport device (175, 176) for accepting a plurality of formed filters from the punching and forming device and transporting the accepted filters to the insertion device, a second transport device (177) for accepting a plurality of formed filters from the punching and forming device and transporting the accepted filters to the insertion device. The first transport device (175, 176) and the second transport device (177) are movable with respect to each other.
