摘要： Small workpieces to be coated with plastic material are preheated and dropped onto a fluidized bed of plastic powder subjected to compound vibratory motion which causes the powder and the workpieces to move along a helical ramp onto a screen overlying the point of entry, with some of the particles fusing onto the workpiece surfaces to form a film. The remainder of the powder, on reaching the screen, drops back onto the bed as the coated workpieces move on to a receptacle. Fresh workpieces are deposited on the bed through one or more chutes traversing the screen; to prevent the rise of any particles through the chutes, a downward airflow is created therein.

摘要： The instant invention relates to a method for preparing paraffin-sulphonic acids by photochemical sulphoxidation of paraffinic hydrocarbons. The invention also relates to a device for carrying out this method.The invention relates more particlarly to a method for continuously preparing paraffin-sulphonic acids by photochemical sulphoxidation of paraffinic hydrocarbons comprising the steps of reacting a gaseous mixture of sulphurous acid anhydride and oxygen with a liquid paraffiaic phase and injecting at least a portion of said gaseous mixture into said liquid phase in the form of a finely divided dispersion in a recycling fraction of said paraffinic phase which carries said gaseous mixture.
