20150276693 | Safety System for Connection to a Toxic Gas Detector and a Power Feed - A safety system for connection to a toxic gas detector and a power feed, comprising a first connection to the detector, a second connection to the power feed, and an interrupt device coupled to said first and second connections, the interrupt device including a circuit for detecting a toxic gas signal from said first connection, and a circuit for permitting, through said second connection, power to flow through the power feed wherein the detecting circuit activates said permitting circuit if the toxic gas signal represents a toxic gas concentration below a predetermined level. | 10-01-2015 |
20130021160 | Safety System for Detecting and Controlling Toxic Gas - A safety system and method for connection of a toxic gas detector to a toxic gas producing engine, comprising an interrupt device coupled to connections to the detector and the engine, including a toxic gas signal detecting circuit and a circuit for permitting starting of the engine. In one embodiment, the permitting circuit is activated if the safety system is healthy and fully functional. Similarly, a safety system and method for connection of a toxic gas detector to a toxic gas supply, comprising an interrupt device coupled to connections to the detector and the toxic gas supply, including a toxic gas signal detecting circuit and a circuit for permitting of flow from the toxic gas supply. In both embodiments, the detecting circuit activates the permitting circuit if the toxic gas signal represents a toxic gas concentration below a predetermined level. | 01-24-2013 |
20130021119 | Electromechanical Switch for Controlling Toxic Gas - An electromechanical switch comprising a plunger, a first switch in contact with the plunger in a first position of the plunger, in which a connection of the switch is open, a button in sliding contact with the plunger, and a solenoid in contact with the plunger in a second position of the plunger, in which a connection of the first switch is closed. | 01-24-2013 |
