A screen includes a screen with a screen frame and a screen filter. The screen frame includes lateral frame members on opposite lateral sides of the screen frame. At least one gear rack extends along at least one frame member of the lateral frame members. The screen may be utilized in a shaker system to process a fluid (e.g., drilling fluid).

The present invention provides a structure for assembling and disassembling a dirt suction head to/from a filter bag, comprising a first connection piece and a second connection piece; one end of the second connection piece is detachably connected to a connection pipe of the dirt suction head, and the other end of the second connection piece is provided with a holding cavity; one end of the first connection piece is connected to an opening of an end of a filter bag body, and the other end of the first connection piece is assembled into the holding cavity; or a circumferential side edge of the opening of the filter bag body is tightly pressed and fixed between an outer side wall of the first connection piece and an inner side wall of the holding cavity, which has achieved a quick assembling and disassembling and smooth external aesthetics of a connection position.

This collecting apparatus collects foreign matter mixed in condensate in/from a condenser of a steam turbine plant, and comprises a first foreign matter collector and an in-condenser collector. The first foreign matter collector is provided on an upstream side of a condensate pump in a pipe connecting a drain outlet provided to the bottom portion of the condenser and the condensate pump to each other, has an opening having a first dimension, and collects foreign matter while passing the condensate therethrough. The in-condenser collector is provided inside the condenser, has an opening having a second dimension larger than the first dimension, and collects foreign matter while passing the condensate in the condenser therethrough toward the drain outlet.

In some examples, a filter assembly may include a filter including a first gasket having a first channel adjacent to a first side of the filter and a second gasket having a second channel adjacent to a second side of the filter. The first gasket and the second gasket may include a beveled surface adjacent to the filter. The first channel and the second channel may include a diameter of from about 0.01 mm to about 0.5 mm. A finger tightening system may securely hold the filter without any leaks.

A beverage dispenser comprising: a cartridge receiving chamber 108, the chamber comprising a water inlet 112 and a treated water outlet 114 configured to connect to a cartridge water inlet and a treated water cartridge outlet of a water treatment cartridge, respectively; a cartridge seat 116, slidingly displaceable within the cartridge receiving chamber 108 between a cartridge operative position in which the cartridge water inlet and the treated water cartridge outlet establish a fluid communication with the water inlet and the treated water outlet of said chamber, respectively, and a cartridge extraction position in which the cartridge water inlet and the treated water cartridge outlet are disengaged from the water inlet and the treated water outlet of the chamber, respectively, the cartridge seat configured to engage a seat-receiving location formed at an external wall portion of said cartridge when received within the cartridge receiving chamber; and a user accessible actuation member 120 switchable between a locked position and an unlocked position, the actuation member being configured to slidingly displace the cartridge seat between said cartridge operative position, corresponding to said locked position, and said cartridge extraction position that corresponds to said unlocked position.

A tool for draining and removing a vehicle filter (e.g. an oil filter, an air filter, a coolant filter, a fuel filter, or the like) from a vehicle, and a method for removing a vehicle filter from a vehicle. The tool includes a perforator for providing a perforation in a vehicle filter; a housing comprising a cavity and an opening therein for receiving a fluid from a perforation in a vehicle filter into the cavity, the perforator at least partially located in the cavity, and the opening being configured such that least one of the perforator and a vehicle filter are positionable therethrough; and a gripper connected to the housing and comprising a gripping surface for engaging and gripping a vehicle filter to restrict relative rotation between the gripper and the vehicle filter to permit rotation of a vehicle filter by rotation of the tool.
