摘要： A process is provided for making a distinction between solid, porous materials, e.g. thermoplastics, having surfaces which are either untreated or treated to render them measurably impermeable to volatiles. The surfaces are first exposed to a high concentration of a volatile fluid which is removed after a fixed time period. The surfaces are then exposed to an environment, e.g. a vacuum, to cause the volatile fluid to back-diffuse and the fluid that back-diffuses is measured. The rate at which the fluid back-diffuses from the untreated surface is considerably greater than that of the treated surface.
摘要翻译：提供了一种用于区分固体，多孔材料的方法，例如。热塑性塑料具有未经处理或经处理以使其对挥发物具有可测量的不渗透性的表面。表面首先暴露于高浓度的挥发性液体，其在固定时间段之后被去除。然后将表面暴露于环境，例如，真空，使挥发性液体反向扩散，并测量反向扩散的流体。流体从未处理的表面反向扩散的速率明显大于被处理表面的速率。

摘要： This invention is directed to an apparatus for subjecting an article to shot blasting under cryogenic conditions which comprises a housing encompassing an entry station, an impacting station and an exit station. In connection with the housing, there are means provided for transporting an article to be shot blasted sequentially from the entry station, through the impacting station, and then to the station. A connection is made to the housing permitting the introduction of a cryogen into the impacting station thereby maintaining such station at a cryogenic temperature. The apparatus also has a means for directing media at a high velocity so as to impact upon an article to be treated while such article is being transported through the impacting station. The apparatus of the invention also functions to rotate the article while it is being transported through the impacting station, thereby permitting the stream of media to contact all critical portions of the article.
