coating of the surface of the work- piece; introducing an electrolyte into the zone created between the anode and the cathode by causing it to flow under pressure through one or more holes, channels, or apertures in the anode and im- pinge on the cathode; and apply- ing a voltage between the anode and the cathode and operating in a regime in which the electrical current decreases or remains sub- stantially constant with increase in the voltage applied between the anode and the cathode and in a regime in which discrete gas bub- bles are present on the surface of the wokpiece during treatment.

ULTBAFILTBATION MEMBRANE

U.S. Patent 5,958,989. Sept. 28, 1999

I-F. Wang et al., assignors to USF Filtration and Separations Group Inc., Timonium, Md.

A method of preparing an asym- metric integral polymer mem- brane for ultrafiltration compris- ing providing a casting dope comprising a sulfone polymer, a solvent, and a nonsolvent, in ra- tios sufficient to form a homoge- neous solution or a colloidal dis- persion; casting the dope to form a thick film; coagulating the thin film in a quench bath; and recov- ering an ultrafiltration mem- brane having an asymmetry ratio of at least about 20, said mem- brane being substantially free of macrovoids.

ULTRAVIOLET-CURABLE

COMPOSITION

U.S. Patent 5,959,020. Sept. 28, 1999 M.R. Oliveri, assignors to Shamrock Technologies Inc., Newark, N. J.

A method for making an ultravio- let-curable composition compris- ing mixing at least one wax, at least one radiation-polymerizable compound, and at least one inhib- itor of polymerization; dissolving by heating to provide a mixture of radiation-polymerizable com- pound, wax, and inhibitor, wherein the heating step is at a temperature that is insufficient to activate polymerization of the radiation-polymerizable com- pound; cooling to provide a dis- persion of wax particles in the radiation-polymerizable com- pound; and micronizing the dis-

Removing heads before the plating build-up is excessive, prolongs the life ot the Dangler Assembly. INEXPENSIVE. Field studies have shown that using our disposable heads costs just pennies per barrel load to use.
