Abstract: Extraction of a fluent material from a pressurized system containing same such as CFC for reclamation is effected into a container by reducing the temperature of the container to a sufficiently cold temperature to generate a vacuum within the container sufficient to extract the CFC from the system to be extracted. The container is cooled by placing the container into an insulated drum containing a glycol bath within which is provided an evaporator duct shaped with a plurality of separate duct portions lying in horizontal planes and spaced vertically with each portion interconnected to the next by a vertical section of the duct. Into the duct is injected carbon dioxide from a compressed liquid supply which is passed through a metering orifice tuned to the length and shape of the duct so that evaporation takes place by the end of the duct. Any liquid remaining at the end of the duct as the temperature cools is returned by a diverter valve into the gylcol bath for additional cooling effect.

Abstract: An auto electric tester has been provided that is simpler in construction, easier to manufacture and can expedite the location of several electrical problems more easily than all known prior art. The tester comprises a casing, circuitry mounted within the casing, four electrical conductors extending from the casing and connected to the circuitry.
