ColorCode UnLimited Corp. of Cambridge, Mass., has developed tiny, color-coded plastic tags that could identify the origin of explosives. President Harry Shamir said the tags could be mixed in with explosives at a manufacturer's plant. Criminal investigators could trace the origin of an explosive by examining the tags.
The patented technology uses pigmented film sheets bonded together, then cut into strips and chopped to make tags about 1 millimeter square and 0.2 millimeters thick. The firm also developed technology to read the tags using their unique color sequences. Shamir said he is looking for investors to help commercialize the technology.

PU boards cut time to make prototypes
Cured polyurethane boards help reduce prototype development time at Siemens Automo-tive's Chatham, Ontario, plant.
Siemens uses Ren Shape 450 from Ciba-Geigy Corp.'s Formulated Systems Group in East Lansing, Mich., to make molds for vacuum forming polypropylene models of auto parts.
Siemens laminates the boards into blocks, then cuts and machines them into molds that are good for as many as 100 vacuum formed parts.
