Various embodiments for a drain debris straining assembly are described, where the drain debris straining assembly can be positioned inside a drain to collect hair and other debris. A drain debris straining assembly in accordance with an embodiment of the present application includes a basket assembly. The basket assembly includes a basket body surrounding a hollow core and at least one opening configured to filter fluid to entrap debris. The basket assembly further includes a flexible rib configured to compress against an internal diameter of a drain flange to form a seal between the basket assembly and the drain flange. The drain debris straining assembly may also include a pop-up assembly having an interference ridge sized and positioned to contact at least one inner wall of the basket assembly to retain a vertical position of the pop-up assembly relative to the basket assembly.

A system, a cartridge and a dispensing valve for eliminating a drift or sag in BCDMH output from an inline dispensing valve containing a dispensing cartridge mountable within the inline dispensing valve with the dispensing cartridge containing a batch of water erodible cluster inhibiting BCDMH particles to provide a linear output flow of BCDMH which is responsive to flow of water though a cartridge in the dispensing valve and a method of obtaining a linear output in a dispensing system by increasing the size of particles in a dispensing cartridge in the system.

A fuel injector assembly includes a fuel injector and an annular filter coupled with the fuel injector, the annular filter being snap-fitted with one of a nozzle case or an injector body of the fuel injector and slip-fitted with the other of the nozzle case or the injector body. The annular filter has a perforated wall forming a filtration screen covering an actuation fluid inlet formed in the nozzle case and positioned upstream of the actuation fluid inlet to trap particulates in incoming actuation fluid.

A starch separation system for an ethanol plant includes a dry fractionization system, a fiber blender, a refiner, a fiber liquefaction tank and a fiber wash system. A starch separation method includes the steps of providing a dry fractionization system receiving corn from the ethanol plant and fractionating the corn into corn oil, corn fiber, corn grits, corn, endosperm flour and germ cake. The corn components are converted to sugar and the sugar is converted to ethanol. A converted fiber stream is input to the fiber wash system for producing fiber wash water for input to the ethanol plant.

Described are apparatus, systems, and methods of improving cleaning of, e.g., stairs of swimming pools. Automatic swimming pool cleaners (APCs) capable of autonomous movement within water-containing vessels may be utilized to provide enhanced cleaning of sections of the vessels containing stairs or other angled surfaces.

A quick release pool skimmer basket apparatus includes an adjustable attachment apparatus, a basket having a sidewall, a filter element coupled to the sidewall to move between an open position and a closed position, and a handle extending upwardly from the basket. A trigger in the handle is operatively coupled to the filter element to hold the filter element in the closed position. Activation of the trigger releases the bottom from the closed position to the open position.
