Disclosed is a filter water spout attached to a basin faucet that comprises: a connection nozzle screwed to a washbasin faucet outlet and extending a vertical connection tube downward; an elbow pipe in which a vertical receiving pipe is formed in a vertical direction and a horizontal receiving pipe is formed in a horizontal direction ; a nozzle body having a horizontal connection tube formed on the side and having an open top ; a nozzle cap coupled to an upper portion of the nozzle body; a horizontal rotation member for allowing the vertical connection tube of the connection nozzle to be rotatably coupled to the vertical receiving pipe of the elbow pipe; and a vertical rotation member for allowing the horizontal connection tube of the nozzle body to be rotatably coupled to the horizontal receiving pipe of the elbow pipe.

Provided are a nucleic acid extraction and purification device and a biochemical molecule extraction and purification device, belonging to the field of experimental supplies. Both devices have the functionality of a test tube, and thus can hold a liquid to perform preprocessing extraction and purification of nucleic acids or biochemical molecules such as nucleic acids, i.e. achieving a process of cell rupture. Furthermore, both devices can quickly and easily transfer liquid to the extraction membrane, achieving the extraction and purification of nucleic acids or biochemical molecules such as nucleic acids. Furthermore, the two devices do not need to manually fit with a pipettor during the process of liquid transfer or use an automated robotic arm and a mechanical pipettor to complete the process of liquid transfer.

An in-tank fuel pump assembly and mounting system is disclosed which may be configured for mounting inside a fuel tank. The assembly includes a pump housing, pump mounted to the housing, and pressure relief valve. The housing may comprise upper and lower pump housing units coupled together. The upper housing unit is configured for mounting to a tank opening, which in one implementation may be the fuel fill opening. The lower housing unit extends into the tank to approximately the bottom of the tank. A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump housing may include an integral vapor trap.

The present invention discloses a filtering device used for removing impurities in a mixture of biological diatomite, which relates to the technical field of sewage treatment. This device includes a plurality of deflectors evenly distributed in multiple layers in the vertical direction. Each deflector includes a shell and a top plate. There is a filter unit symmetrically arranged on the left and right sides of each deflector. The top of the shell is covered with a top plate hinged with the depressed plate. The bottom of the shell is provided with water inlets which communicate with the shunt pipe, and the upper parts of the left and right side walls of the shell are provided with overflow ports. The shell also has a plurality of diversion folding plates located below the overflow ports and vertically staggered and distributed on the left and right side walls. The filter unit includes an inclined water guiding groove and a filtering plate.

Filter assemblies for filtering wash fluid to be circulated by a circulation pump in a dishwasher appliance are provided. A filter assembly includes a first filter member, a second filter member, a first discharge blade, and a second discharge blade. The filter assembly further includes a shaft extending through the first filter member, the second filter member, a first central bore hole of the first discharge blade, and a second central bore hole of the second discharge blade. The shaft includes a body which has an outer surface, the outer surface including a first threaded portion, a second threaded portion, a first unthreaded portion, and a second unthreaded portion. The plurality of first inner threads mesh with the first threaded portion and the plurality of second inner threads mesh with the second threaded portion.

A method for manufacturing a strainer, such as a strainer of an ejector used to transfer fuel between two tanks of an aircraft or to supply fuel to an engine is provided. The strainer includes a conduit whereof a first end is intended to be connected to an inlet of the ejector, and whereof a second end is located within a housing including an open face for the passage of fuel, the open face being closed off by a grate acting as a filter. The method includes the step of manufacturing the conduit, the housing and the grate of the strainer as a single monobloc part.
