20130160503 | Apparatus and Methods for Restricting Access to a Gas Source - In some embodiments, a locking cap system useful for controlling access to a gaseous system includes an outer cap, an inner lock, a metallic key and a magnetic opener. The inner lock rotates freely relative to the outer cap and is releasably engaged with the gaseous system. The metallic key is configured to be at least partially axially movable within the inner lock and the outer cap. The magnetic opener is useful to bias the metallic key so that the metallic key engages the inner lock and the outer cap simultaneously to allow the inner lock to rotate concurrently with rotation of the outer cap and engage or disengage from the gaseous system. | 06-27-2013 |
