rial, placed in the container and facing the first electrode, in such a manner that the introduced composite electroplating liquid spouts downward against the inside bottom surface of the container; flowing upward the spouted composite electroplating liquid through an upward flowing path formed between the first electrode and the second electrode; and applying an electric current between the first electrode and the second electrode, to form a composite plating layer comprising a metal matrix and the fine solid particles uniformly dispersed in the metal matrix on a surface of the first elec- trode or the second electrode.

Dendritic Cadmium Powder U.S. Patent 5,496,462. Mar. 5, 1996 1. Albert, assignor to Metaleurop S.A., France

A process for obtaining a fine powder containing dendritic cadmium, comprising electrolytic production of metallic cad- mium on an electrode, with a current den- sity between 700 and 1500 A/m2, with a cadmium concentration in the electrolyte

between 3.5 and 1.5 kg/m’, and with an electrolytic solution composed of cadmium sulfate and sulfuric acid, the sulfuric acid content being between 5 and 100 g/L, whereby a sponge consisting of tangled polymorphic dendrites is formed.

Reducing Volatile Organic Compound Emissions U.S. Patent 5,496,5&?5. Mar. 5, 1996 CR. Hamilton et al., assignors to Go/den Technologies Co. Inc., Golden, Cofo.

A method for reducing volatile organic compound emissions in the application to a surface of a VOC-containing coating, com- prising contacting with an effective amount of a finishing agent having a pH of 6.0 to 9.0 comprising terpene to remove oils present on the surface; and applying an amount of a VOC-containing coating effec- tive to coat the surface, said VOC-contain- ing coating including a compound selected from the group consisting of toluene, me- thylene chloride, isopropyl alcohol, butyl alcohol, and mixtures thereof, said VOC-

containing coating selected from the group consisting of inks, paints, plastic coatings, and mixtures thereof.

Apparatus for Galvanizing Linear Materials U.S. Pafent 5,496,568. Mar. 5, 1996 K.K. Maitra et al, assignors to Allied Tube & Conduit Corp., Harvey 111.

In a continuous process for galvanizing metal conduit, a method of applying molten zinc to a cleansed and preheated metal con- duit to be galvanized by providing an inert gaseous environment over the source; propel- ling a jet of molten zinc from the source through the gaseous environment; and pass- ing the conduit axially through the jet.
