An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) by selectively removing nitrogen to supply an oxygen-enriched product gas stream.
Amine gas plant at a natural gas field. Amine gas treating, also known as amine scrubbing, gas sweetening and acid gas removal, refers to a group of processes that use aqueous solutions of various alkylamines (commonly referred to simply as amines) to remove hydrogen sulfide (H 2 S) and carbon dioxide (CO 2) from gases.
Usually, the work is done over a special dissipative table mat, which allows a very slow discharge, and under the air gush of an ioniser. The ionization falls off very sharply with distance (even in ducting), so air ionization is rarely used for this purpose, and only for items immediately adjacent to the actual ionizer.
Water conditioners are formulations designed to be added to tap water before its use in an aquarium. [1] [2] If the tap water is chlorinated then a simple conditioner containing a dechlorinator may be used.

Example of a particle collimator. A collimator is a device which narrows a beam of particles or waves. To narrow can mean either to cause the directions of motion to become more aligned in a specific direction (i.e., make collimated light or parallel rays), or to cause the spatial cross section of the beam to become smaller (beam limiting device).
A typical flyswatter. A flyswatter (or fly-swat, fly swatter [1]) usually consists of a small rectangular or round sheet of a lightweight, flexible, vented material (usually thin metallic, rubber, or plastic mesh) around 10 cm (4 in) across, attached to a handle about 30 to 60 cm (1 to 2 ft) long made of a lightweight material such as wire, wood, plastic, or metal.
