摘要： A novel apparatus is provided for removing with a treating fluid surface films that are hydrophilic in nature and comprise a less dense liquid component. The hydrophilic film is removed from non-absorbing surfaces such as metal, glass and plastics and may contain dissolved solids. The hydrophilic film is substantially immiscible in the more dense cleansing liquid. In a particular embodiment the more dense liquid is a cleansing fluid and the less dense hydrophilic component is present as a contaminant. The apparatus includes a tank (12), a separator chamber (14) and a holding chamber (16). The less dense liquid is removed from the upper part of the separator chamber 14. The configuration of separator chamber (14) effects rapid separation of overflow liquid into an upper layer of the less dense liquid and a lower layer of the more dense liquid. In another embodiment of the apparatus, a second separator chamber (89) and a second holding chamber (90) are included.

摘要： Temporary corrosion protection for fresh metal surfaces may be obtained by depositing a thin film of a protective organic compound, particularly a fatty acid ester, from a solvent, preferably a fluorocarbon on the surface to be protected. The film-forming esters are chosen to be self-removing by evaporation so that no cleaning is needed before carrying out processes which require a clean metal surface.

摘要： The present invention provides a novel apparatus and process for generating a vapor spray from a volatile fluid. In the invention, the volatile fluid is heated to a temperature just below its boiling point prior to being discharged from heat exchanger (18, 46). In one embodiment of the apparatus, heat exchanger (46) contains a diffusion plate (48) to ensure that the volatile fluid is at the selected temperature when discharged from the heat exchanger. In this embodiment, the apparatus further includes a pressure-responsive valve (40) and a bypass line (42) so that a selected pressure is maintained downstream from pump (34).The novel process of the present invention includes the step of heating the volatile fluid within heat exchanger (18, 46) to a selected temperature just below its boiling point prior to discharge from the heat exchanger. In one embodiment, the process further includes the step of impinging the volatile fluid stream as it enters heat exchanger (46) onto diffusion plate (48) so that it is ensured that the volatile fluid is at the selected temperature upon discharge. In this embodiment, passing of the fluid drawn from reservoir (32) is accompanied by modulating the flow of the drawn fluid through bypass line (42) connecting pump (34) and reservoir (32), whereby a selected pressure is maintained downstream from pump (34).

摘要： Quaternary azeotropic mixtures of 1,1,2-trichloro-1,2,2-trifluoroethane, methylene chloride, methanol and cyclopentane are provided. These azeotropic mixtures are useful as solvents to remove buffing compounds residues. These mixtures are useful not only because of their high solvency characteristics but also because they exhibit essentially the constant boiling characteristics of an azeotrope which is formed between these components, thereby facilitating handling and purification of the solvent mixtures without significantly altering their compositions. [The quaternary mixtures disclosed herein exhibit certain advantageous solvency characteristics of glycol based compositions, over the known binary or ternary azeotropic systems containing 1,1,2-trichloro-1,2,2-trifluoroethane, methylene chloride, methanol and cyclopentane.]
