摘要： A heater for fluid flow components is disclosed. The heater has heat transfer surfaces that engage the component. The transfer surfaces are mounted on jaws that are movable to engage the component. The jaws have massive portions that act as heat reservoirs to maintain a constant temperature in spite of rapid cooling when gas is allowed to expand freely from the component. The jaws are heated by electrical resistive heating elements that are sealingly mounted within the massive portions. The sealing engagement allows the heater to be used in hazardous environments.

摘要： An apparatus for containing and scrubbing toxic or corrosive gases from a leaking pipe or cylinder is provided. A gas passageway attaches at one end to a leakage location on a pipe or cylinder, and at the other end to an air operated exhauster. The air operated exhauster, through the input of a non-flammable purge gas, creates an exhaust flow from the leakage location to a drum which is attached to the air operated exhauster. The drum contains a scrubbing media which, when it contacts the leaked gas, cleans or removes the harmful component, thus allowing release to the atmosphere of the cleaned air.
