A solenoid valve is an electromechanically operated valve. Solenoid valve is used to control the fluid and gas automatic based components, belonging to the actuator; the valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. Multiple solenoid valves can be placed together on a manifold.  
"This report studies the Ozone Generation Technology market
Ozone generators work by combining oxygen (O2) with energy to produce ozone (O3). When the oxygen molecules are exposed to energy, the two atoms are broken apart. The single oxygen atoms quickly bond in groups of three to form ozone.
In the report, we mainly focused on the electrolytic ozone generators."
Description
A Steam Trap is an automatic valve that allows condensate, air and other non-condensable gases to be discharged from the steam system while holding or trapping the steam in the system. In industry, steam is used regularly for heating or as a driving force for mechanical power. Steam Traps are used in such applications to ensure that steam is not wasted.
An electric arc furnace is a high-temperature furnace that uses high-voltage electric arcs to make steel. Electric arc furnaces are a feature of the minimills that recycle iron and steel scrap into new steel products. Arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary steelmaking.

"Marine VHF radio refers to the radio frequency range between 156.0 and 174 MHz, inclusive. 
The ""VHF"" signifies the very high frequency of the range. In the official language of the International Telecommunication Union the band is called the VHF maritime mobile band. In some countries additional channels are used, such as the L and F channels for leisure and fishing vessels in the Nordic countries (at 155.5–155.825 MHz)."

Slot Machines are casino gambling machines with three or more reels which spin when a button is pushed. Slot Machines are also known as one-armed bandits because they were originally operated by one lever on the side of the machine as opposed to a button on the front panel, and because of their ability to leave the player in debt and impoverished
