A device for baiting insects which includes an anchor tube that is placed in the ground, a base plate that attaches to the anchor tube, a cover that attaches to the base plate, a bait cup placed in said anchor tube and that sits beneath the ground, and a termite media support rod that attaches to the bait cup and sits in the anchor tube, beneath the ground, the key to open the cover and access the bait, the anchor tube being molded into one integrated piece with a continuous spiral fin or threaded member that acts as a screw mechanism when inserting the station into the ground and the base plate, which sits at ground level, includes insect entry openings; a cover covers the base plate and bait cup, protecting the bait from the elements; and optionally a termite media support rod, which includes a disk molded on the bottom thereof used to hold material for termite monitoring.

Outdoor refillable bait station

An apparatus for use with a water treatment unit that indicates the end of life of the unit. The apparatus comprises a housing with at least one opening for the passage of liquid to a chamber, formed by the interior of the housing and the water treatment unit. The chamber includes a support member mounted to the housing. A float is rotationally mounted on the support member. The support member limits float movement to a predetermined distance upon each rotation of the float, resulting from each cycle of the water treatment unit. Once the float has made a specific number of rotations and has travelled the complete distance of the support member as water fills and drains from the chamber, the float rests in a position where it is visible through an opening in the housing, indicative of the end of life of the water treatment unit.

End of life mechanism for water treatment cartridge

Water filter cartridge

An apparatus for use with a water treatment unit and in particular, those having a treatment cartridge, that indicates the end of life of the unit. The apparatus comprises a housing with at least one opening for the passage of liquid to a chamber, formed by the interior of the housing and the water treatment unit. The chamber includes a support member mounted to the housing. A float is rotationally mounted on the support member. The support member limits float movement to a predetermined distance upon each rotation of the float, resulting from each cycle (use) of the water treatment unit. Once the float has made a specific number of rotations and has travelled the complete distance of the support member (as water fills and drains from the chamber), the float rests in a position where it is visible through an opening in the housing, indicative of the end of life of the water treatment unit.

The invention provides a method for preparing polyhalide resin disinfectants. The step of the method involves circulating an effective amount of a polyhalide salt carrier solution between an effective amount of elemental halide and a strong base anion exchange resin until substantially all of the resin is converted to the polyhalide form. The elemental halide and the resin are separately disposed but connected so that the polyhalide salt carrier solution can be recirculated until all of the elemental halide is transferred to the resin. The method of the invention can be used to form a tri-iodide or penta-iodide resin, or mixed form of the resin including IBr.sub.2.sup.-/I.sub.2.sup.-.
