Abstract: A sanitizing apparatus for writing utensils comprising a housing assembly and an ultraviolet and ozone generating assembly housed therein. The housing assembly comprises a top wall, a base and four walls. The first and second walls are perpendicularly disposed with respect to the third and fourth walls. The third and fourth walls are lateral walls. The housing assembly also comprises an angled wall that protrudes outwardly beyond the top wall and beyond the first wall defining a tray that terminates with a lip for preventing the writing utensil from falling off. A battery compartment is also housed within the housing assembly. The ultraviolet and ozone generating assembly radiates the writing utensil within the housing assembly with rays and ozone, to effectively sterilize bacteria and biological germs existing on the writing utensil. A visual indicator notifies a user when the ultraviolet and ozone generating assembly is operating.

Abstract: An improved resettable safety valve for preventing the escape of gas from a closed gaseous system wherein an inlet line is attached to the inlet chamber of the valve and an outlet line is attached to the outlet chamber of the valve. The valve comprises a housing wherein a piston-like plug with a head at one end and a rod-like body at the other end are contained within the housing. The housing includes an inlet chamber sized such that the plug head is movable laterally within the chamber. The housing includes a main chamber adjacent the inlet chamber and along the same axis as the inlet chamber and an outlet chamber adjacent the main chamber and along the same axis the main chamber sized such that the rod-like end of the plug fills the chamber at one end thereby preventing the flow of gas through the outlet chamber when the rod-like body is within the outlet chamber.
