Abstract: A device and system for purifying a fluid is provided. The system includes a tank having an interior space and a media container disposed within the interior space. A valve is provided that cooperates with an element within the interior, the valve being movable between an open and a closed position. The valve being biased to the open position when the element is not positioned within the interior space, wherein the interior space is fluidly coupled to the atmosphere in the open position. The valve further being configured to move to a closed position when the element is positioned within the interior space.

Abstract: The present improved magnetic coil tattooing machine incorporates an armature assembly comprising an actuator appendage. The actuator appendage facilitates the actuation of an interrupter switch assembly that is remotely located in relation to the armature assembly. As a result of the described improvements it is now possible to adjust the activation timing of the interrupter switch assembly. An additional and unexpected advantage is a smooth homogenous operation of the interrupter switch assembly rendering the known tuning procedure of prior art obsolete.
