Drain pump

A pump cartridge comprising an external housing including a lateral wall, a first fin extending from a first side of the lateral wall, and a second fin extending from a second side of the lateral wall. The second side of the lateral wall may be opposite the first side of the lateral wall, such that the fins are on opposite sides of the lateral wall. The pump cartridge may be part of a pumping system further comprised of a chassis comprising a pump basin including an interior side wall, a first tab extending inwardly from the interior side wall, and a second tab extending inwardly from the interior side wall and opposed to the first tab. The first fin of the cartridge is reversibly engageable with the first tab of the chassis and the second fin of the cartridge is reversibly engageable with the second tab of the chassis.

Modular pump and pumping system including same

A liquid level control module comprising an elongated tubular housing immersible through a surface of a liquid and into a bulk volume of the liquid, and first, second, and third electrical switches, and first and second floats movable along the tubular housing. The first electrical switch is disposed within a lower portion of the tubular housing, the second electrical switch is disposed within an intermediate portion of the tubular housing, and the third electrical switch is disposed within an upper portion of the tubular housing. Each of the switches has an open state and a closed state. Motion of the first float relative to the first switch changes its state. Motion of the second float relative to the second switch changes its state, and motion of the second float relative to the third switch changes its state. Thus a two-float module may provide three level control signals.

Liquid level control module and apparatus comprising same

A visually observable display comprising a circuit board including at least one illuminator emitting light outwardly from a surface of the board, a light transmissive display window pane operable to receive light at an inner surface and transmit the light through an outer surface, and an insert disposed between the illuminator and the display window pane. The insert comprises an elongated light distributing conduit receiving light from the at least one illuminator at a first location in a direction substantially perpendicular to the display window pane, distributing the light transversely through the light conduit along the inner surface of the display window pane, and redirecting the distributed light outwardly along an outer wall of the conduit and outwardly through the window pane. The display may include multiple light illuminators emitting light outwardly from the board surface and into the light distributing conduit at discrete locations along the conduit.

Display panel

A method for static mixing in a waste water settling tank to increase the percentage of recovery of entrained solids from the waste water comprising a settling tank having a hopper bottom defining a sludge hopper, a deflector dome centrally disposed within the space contained in the hopper bottom, and an inlet pipe for introduction of waste water containing second entrained solids into the settling tank and having a discharge outlet in proximity to the underside of the deflector dome. Influent waste water is directed vertically upward into the center of the deflector dome which distributes the influent radially into contact, preferably turbulent, with previously introduced waste water containing first entrained solids to cause coalescence of the first and second entrained solids to form larger particles having increased settling velocity.
