Abstract: The plugging of fluidized solids in long transfer lines is a particularly troublesome problem from an operational standpoint. Obstructions are cleared by closing off the transfer line at both ends, introducing an inert (non-deleterious) gas into the conduit at a few atmospheres pressure above the pressure at the conduit output, maintaining the gas pressure for a time to allow pressure equilization along the conduit, and thereafter opening the conduit outlet to permit the plugged solids to refluidize and then clear the line.

Abstract: A method of controlling ectoparasitic Acarina that bore into and through the dermal integument of warm blooded animals by orally administering an 2-aryl-1,3-indandione and derivatives to said animals in an amount sufficient to kill said ectoparasites.

Abstract: A degassing or purging process is disclosed for the removal of unpolymerized gaseous monomers from solid olefin polymers. The disclosed process comprises conveying the solid polymer, e.g. in granular form, to the top of a purge vessel by means of an inert gas stream, feeding an inert gas stream to the bottom of the purge vessel and countercurrently contacting the solid polymer with the inert gas purge stream to strip away the gaseous monomers evolved from the solid polymer, and recycling a portion of the resulting stream to the purge vessel. In one embodiment, the recycle serves as the conveying gas and in another embodiment as the purge stream. The process is especially useful in purging gaseous unpolymerized hydrocarbon monomers from low pressure-polymerized, low density ethylene-hydrocarbon copolymers.
