A method cleaning a contaminate solvent used to treat a gas stream, for example a contaminated glycol or a contaminated amine stream, by vacuum evaporation using a mechanically-maintained horizontally-orientated thin film evaporator, where the contaminant material is recovered from the thin film in solvent- free form, as either a heavy organic material or as free flowing salts. The gradient magnetic field bio-medical unit is operable to generate a gradient magnetic field in a proximal area of a body object within a host body, wherein a constant magnetic field is present in the proximal area of the body object. The movement parameter is mapped to the color hues by apparatus comprising a user interface that allows the user to input color band resolution and a local range of relative parameter values. The process A writes contents of requests in its own request storing area, and the OS notifies the IO device that there is an unprocessed request by use of the address for the pending register. The drive is designed in such a manner that the crankshaft is suspended in the housing.
