Abstract: A Multi-Source electronic lighting device for use as a signal or illuminator. Light is created by a plurality light emitting diode elements which are encapsulated in a light transmitting medium. A curved cylindrical lens is contoured to cooperate with the location of the light emitting diode elements to create a composite light beam with a controlled beam pattern which is elongated in a defined plane. The intensity of the projected light beam is maximized through the efficient collection of created light.

Abstract: In the context of an oil and gas drilling rig flare system, a purge system is introduced so that in the event of a flammable gas release at the rig, the purge system can be activated. Activation of the system shuts off gas supply from a separator in the mud return system to the flare line and initiates a purge of an inert gas. Any ignition sources in the flare line are immediately turned off. The purging cools the flare line to a point where it cannot act as an ignition source itself. The inert gas prevents the presence of oxygen in the flare line to additionally prevent combustion within the flare line. The flowing inert gas cools the flare line to the point where it cannot ignite any escaping gas from the rig floor. The system can be manually or automatically actuated.
