Abstract: A method of preventing scale and deposit formation on the surfaces of mist eliminators in wet scrubber flue gas desulfurization systems which utilize intermittent wash cycles which comprises coating the surfaces of these mist eliminators with a thin coating of talc.

Abstract: As a conditioning step for wrapping a plurality of articles in a low density polyethylene shrink film, perforations are formed in the shrink film for receiving machine elements utilized in performing the wrapping operation, the film being moved continuously between a pair of infeed rolls and a pair of outfeed rolls between which a rotatable mandrel is disposed and which includes perforating knives thereon for engaging the film while the film is moved continuously, the perforating knives being disposed on the opposite side of the web from a rotatable back up roll having cavities formed therein for receiving the ends of the perforating knives in such manner that the web is maintained under tension throughout the perforating process while the backup roll serves to prevent sidewise movement of the web due to web perforating action of the perforating knives.

Abstract: For applying heat to groups of articles disposed within a wrapper of shrink film whose ends are overlapped and disposed below the articles, a tunnel is provided including a conveyor through the tunnel having air passages therethrough and on which the groups of articles are disposed while being moved through the tunnel, a heater disposed below the conveyor, a primary fan for driving air through the heater and into a conduit which directs heated air through the passages in the conveyor and directly to the overlapped ends of the wrapper together with a fan and conduit for directing heated air at a lower temperature to the ends and sides of the groups of articles.

Abstract: Novel methods for making chlorohydrins are provided using a Lewis acid catalyst with an olefin and peroxy compound or where an enantiomer is desired, a Lewis acid catalyst in combination with a chiral alcohol, particularly glycol, and a combination of a peroxy compound and alkenol. In certain situations, an epoxide may be employed.

Abstract: A method of stabilizing particulate material covered by a liquid electrolyte containing dissolved inorganic salts in which a cathode is placed below the surface of the particulate material and an anode is placed in the liquid electrolyte or in the particulate material so that it is in an electrical relationship with the cathode. An electrical current is then passed betweeen the electrodes for a sufficient time to cause the dissolved inorganic salts to deposit on or between the cathode and the interface of the particulate material and liquid electrolyte.
