A handheld fluid sprayer is configured to draw spray fluid from a reservoir mounted on the fluid sprayer and eject the spray fluid through a nozzle. The reservoir is removably mounted to the fluid sprayer. A priming pathway extends through the fluid sprayer and routes air out of the reservoir to prime the pump. The priming pathway extends from the reservoir and to a side of the pump opposite the reservoir.

A modular structural device for assembling a funnel of a filtration apparatus including a base sheet having a polygonal shape. The base sheet having two sections connected by a hinge along a diagonal from a first corner of the base sheet to a second corner opposite the first corner, the second corner being substantially concave. The device having at least connector having a first part and a second part disposed on opposite sections of the base sheet along opposite edges adjacent to the concave corner. The first part of the connector comprising a projection that extends away from an upper surface of the base sheet. The second part of the connector comprising a depression in a lower surface of the base sheet. The first part of the connector of the modular structural device is configured to interlock with the second part of the connector of another modular structural device.

Equipment for sucking and extracting anodic sludge from cells for electro-refining or electro-winning of metals that allows the continuous and selective extraction of anodic sludge without interrupting electro-refining or electro-winning, preventing the anodic sludge from causing contamination in the copper cathodes and in the time in later stages of metal recovery, where the equipment comprises: a vacuum tank (2) that receives the extracted anode sludge, comprising an outlet valve (21) located in its lower part; a filter (25) resistant to acid (25) inside the vacuum tank (2) for the separation of the anode sludge from the sucked electrolyte so that the anode sludge remains in the filter (25) by a decantation process while the electrolyte passes to the lower part of the tank body; a vacuum system (3), connected to the vacuum tank (2), which generates a vacuum inside the vacuum tank (2) to generate the suction or vacuum aspiration of the equipment; and an anode sludge collector (1) comprising a transparent tube (11) where a first end (12) has a suction nozzle (14) connected, through which the anode sludge enters, and a second end (13) is connected to the vacuum tank (2); a regulating valve (15) mounted at or near said outlet end (13) of the transparent tube (11), which is in communication with the interior of the transparent tube (11) at one of its ends and at atmospheric pressure at the another end, where said regulating valve (15) allows the regulation of the suction pressure inside the anode mud collector (1) and the extraction generated in the suction nozzle (14).

A portion pack for producing a beverage includes a container made of filter material in which an extraction material is arranged. The container has an upper side and a pivotable edge portion that is initially arranged in a closed position to close the upper side of the container. A supporting body encloses at least regions of the container. The container is held closed by a closure mechanism which is adapted to be releasable by moistening the supporting body with water to cause the pivotable edge portion to pivot upwardly to a beverage preparation position in which the upper side of the container is open. The invention also relates to a method for producing a beverage using such a portion pack.

In one embodiment, a sand boil filter apparatus has a filter cone including an inner cone mesh and an outer cone mesh, the inner cone mesh having a finer mesh than the outer cone mesh. A filter tube extends through the hollow interior of the filter cone. The filter tube includes a lower portion disposed below the open apex. The filter tube includes an upper portion disposed above the open base. The upper portion has a plurality of sets of exit openings which are spaced along a length of the upper portion to provide different possible exit heights for the plurality of sets of exit openings, each set including one or more exit openings disposed at an exit height of the filter tube. An exit height adjustment tool blocks all of the exit openings disposed below a set of unblocked exit openings selected to provide a corresponding exit height.
