electrostatically sprayable liquid; a capillary structure, which com- prises a hollow tube having a con- voluted inner surface and being formed of a polymeric material impermeable to the liquid; and means for applying high voltage to the liquid in order to cause the liquid to be projected from the at- omization tip as one or more liga- ments and thereaf ter to break up into a p lu ra l i ty of e lect r ical ly charged droplets.

PREHEATER FOR T H E R M A L OXIDIZERS U.S. Patent 5,810,581. Sept. 22, 1998 G. Martin and D. Chiles, assignors to Smith Engineering Co., Ontario, Calif.

A method for processing one or more gas s t reams containing pal- lu tan ts using a the rmal oxidizer employing a heat exchanger and an oxidation chamber, compris- ing mixing ambient air with a heated gas s t ream from the oxi- dation chamber to form a cooler in te rmedia te gas s t ream; mixing the i n t e r m e d i a t e gas s t r e a m with an inlet gas s t ream to be processed by the oxidizer , to form a r e s u l t i n g gas s t r eam, which has a t empera tu re suffi- cient to subs tant ia l ly e l iminate the condensat ion of organic or inorganic compounds prior to di- recting the resul t ing gas s t ream into the the rmal oxidizer; and di- rect ing a t rea ted gas s t ream ex- i t ing the t he rma l oxidizer for fu r the r processing or releasing it to a tmosphere.

METAL BRIGHTENING C O M P O S I T I O N U.S. Patent 5,810,9,38. Sept. 22, 1998 D.P. Murphy, assignor to Heake! Corp., Plymouth Meeting, Pa.

A process of brightening an un- pa i n t ed dul led meta l surface , which is in a fixed spatial position with respect to at least one glass surface, by contact ing with an aqueous liquid brightening com- position that comprises water and HF 2 ions not provided directly by hydrogen fluoride or it, s aque- ous solutions; and a component of acid(s) with a higher ionization constant, t han HF 2 ions, said aqueous liquid brightening com- pos i t ion not compr i s ing more than 10c~ of hydrochloric acid.

STEEL P ICKLING PROCESS U.S. Patent 5,810,939. Sept. 22, 1998 C. Angel eta/., assignors to EKA Chemicals AB, Babus, Sweden

A method for pickling steel com- prising spraying pickling solution onto steel, the pickling solution containing Fe 2~ and Fe :~ ions from a conduit ; collecting the sprayed pickling solution in a vessel connected to the conduit; and continuously circulat ing the collected pickling solution to re- genera te the pickling solution by oxidizing at least a portion of the Fe ~ ions in the collected pick- ling solution to Fe :~' ~ ions by sup- plying hydrogen peroxide to the collected pickling solution in the conduit.

G A L V A N I Z I N G FLUX U.S. Patent 5,810,946. Sept. 22, 1998 M.W. Cadal, y and A.S. Myerson, assignors to Metals Recy('lb~g Technologies Corp., Atlanta

A method tbr the production of zinc ammonium chloride galva- nizing fluxes from waste materi- als comprising zinc compounds comprising t reat ing with an am- monium chloride solution to form a first product solution, which comprises (NH:,)2ZnC12 and a first

undisso lved mate r i a l s ; adding zinc metal to form a second prod- uct solution; and adding hydro- chloric acid and one or more com- pounds selected from the group cons is t ing of NH4C1, NH:~, or NH4OH to the second product so- lution result ing in the formation of zinc ammonium chloride com- plex salts for use as zinc ammo- nium chloride galvanizing fluxes.
