Abstract: A filter unit includes a body portion that receives a water filter. An engaging portion is coupled to the body portion. A bypass actuator rotates relative to the engaging portion to rotationally and axially operate a bypass valve of a fluid manifold. The bypass actuator drives axial engagement of the engaging portion with a valve assembly of the fluid manifold. The bypass actuator extends through the body portion and the engaging portion.

Abstract: A modular filter manifold includes one or more plates, each plate including connections for one or more filters on a first side, and connections for fluid lines on a second side opposite the first. At least two fluid line connections are provided for each filter connection, with a fluid passage through the plate for each fluid line connection. Each of the fluid passages are independent of one another. The manifold plates can be joined to a support structure to form a manifold to which filters can be attached. Piping can be connected to the fluid line connections to allow flow through the filters in series or parallel flow.

Abstract: A rotary fluid filter including a filter body rotationally mounted within a housing. The housing having a front cap having a main fluid inlet and a backwash outlet, a rear cap having a main fluid outlet and a backwash inlet. The filter body having a front face, a rear face, and a plurality of fluid flow passages each extending through the filter body between the front face and the rear face and having a filter received in each fluid flow passage. The filter body operable to rotate with in the housing such that, for each fluid flow passage, as it is aligned with the main fluid inlet a main fluid is received therein, as it is aligned with the main fluid outlet the main fluid is discharged therefrom, and as it is aligned with the backwash inlet and the backwash outlet a backwash fluid is received therethrough.

Abstract: The invention relates to a method for removing a chemical substance from human excreta, such as faeces and urine, comprising the following steps of: providing a toilet for a person from whose excreta the chemical substance must be removed; releasably connecting a filtering device to the toilet, wherein the filtering device comprises at least one removable cartridge with a filter; transporting the excreta by means of a transport screw from the toilet toward the filter in the cartridge, wherein pressure is exerted on the excreta by means of a plunger; filtering the chemical substance out of the excreta in situ using the filtering device; periodically replacing the at least one cartridge; and processing the replaced cartridge. The invention also relates to a filtering device for application in this method, and a cartridge for use in such a filtering device.

Abstract: A filter cartridge with a longitudinal axis has mounting lugs engaging mating manifold flanges in an appliance to hold the cartridge in the appliance with fluid flowing through the cartridge at a line pressure of X psi while the lugs are designed for a greater, rated pressure Y. Each lug has a deformable portion and an aligned stop portion that are axially aligned. A distance d separates each stop portion from the axially aligned deformable portion. The deformable portion is below the stop portion and located to contact the manifold flange during use. The deformable portion permanently deforms above the rated pressure Y and below a qualification pressure Z that is at least twice the pressure X.

Abstract: A grill device includes a first grill seat and a second grill seat movably connected to the first grill seat such that the second grill seat is movable between a closed position, where the second grill seat overlaps with the first grill seat in an up-and-down direction to define a grill space therebetween for accommodating a food to be grilled, and an opened position. The second grill seat has a fume collecting chamber which is disposed opposite to and in spatial communication with the grill space in the up-and-down direction when the second grill seat is in the closed position so that fumes generated during grilling are dissipated successfully and are spontaneously ventilated and exhausted without the need to provide a power activated impeller, thereby reducing the manufacturing cost and saving energy.

Abstract: An inside-out liquid purification system includes a housing and a cartridge. The housing defines an interior space and includes an inlet at a top side of the housing, a fitting at the top side of the housing and inboard of the inlet, and an outlet at a bottom side of the housing. The cartridge is disposed within the interior space and includes a top cap having an orifice and configured to interlock with the fitting to suspend the cartridge within the interior space, a bottom cap adjacent to and suspended above the bottom side, and a filter having an annular shape and extending between the top cap and the bottom cap with the filter defining a hollow vertical column aligned with the orifice such that liquid enters the cartridge vertically through the orifice and exits the cartridge at least partially radially through the filter.

Abstract: Provided is a head assembly for a water purification filter, which includes a head body, a rotation shaft, and a fastening cap. In particular, the rotation shaft is rotated in the state of being placed on a seat protrusion formed on the head body, and a lower seal member is disposed in the portion where the rotation shaft is placed on the seat protrusion. Accordingly, there can be prevented a problem in which the lower seal member departs from a predetermined location during the coupling of the rotation shaft to the head body so that defective assembly occurs.
