The present invention relates to detection and alarm systems for predicting and detecting the location of spills, leaks, emissions, and/or pollution sources, i.e., unwanted fluid (liquid/gas) flow/escape, at refineries, e.g., oil and gas refineries, and plants, e.g., petrochemical, chemical, pharmac
The present invention relates to detection and alarm systems for predicting and detecting the location of spills, leaks, emissions, and/or pollution sources, i.e., unwanted fluid (liquid/gas) flow/escape, at refineries, e.g., oil and gas refineries, and plants, e.g., petrochemical, chemical, pharmaceutical, and food processing plants, and avoiding said unwanted flow/escape. According to one embodiment, said system comprises at least one detector, at least one battery powered radio frequency transmitter, preferably, according to one embodiment, a 900 megahertz spread spectrum transmitter, and a central processing location which, according to one embodiment, is preferably capable of handling up to 3000 points in a single cell site.

The impact tool system of claim 7 wherein the ultrasonic transducer and the indenters are mechanically tuned to produce a Q-factor of the order of 800.11. A method of ultrasonically reworking a braking rotor or drum comprising ultrasonically impacting a metallic braking rotor or drum surface on said rotor or in said drum with a set of individual randomly ultrasonically driven indenter elements to provide a compressive work surface strength in said rotor or drum surface which exceeds the yield point of the rotor or drum and approaches maximum strength of the rotor or drum.
