Abstract: An electrically conductive polyacetal composition having improved toughness and flexibility, as well as good fluidity and processability. The composition includes an oxymethylene polymer, an elastomeric polyurethane, and an electrically conductive carbon black having a lower structure level (DBP absorption) and larger particle size (lower surface area) than conductive carbon blacks heretofore used in these compositions. The composition includes between about 65 and about 85 percent, by weight, of the oxymethylene polymer, between about 10 and about 20 percent, by weight, of the electrically conductive carbon black, and between about 10 and about 20 percent, by weight, of the elastomeric polyurethane. The electrically conductive carbon black has a surface area BET (N2) of between about 40 and about 100 m2/g, and a pore volume, DBP absorption, of between about 150 and about 350 ml/ 100g. The electrically conductive carbon black used in the present compositions is more easily dispersed in the composition polymers and lessens any increase in melt viscosity during compounding.

Patent CA-2281492-A1 (CA)
Inventor: RUSHMORE DEAN FREDERICK
IPC: A23L27/10
Filed: 1999-09-09
Abstract: Natural cocoa flavor and aroma compositions are prepared by passing a natural aroma gas, preferably from cocoa beans, through one or more condensers to remove water and substantially all the acetic acid present therein. The aroma gas may then be placed into a cryogenic collector in which liquid nitrogen is sprayed directly into the aroma gas stream to rapidly condense the aroma frost suspended in a stream of nitrogen gas, while minimizing contract of the cooled gas with the walls of the collector. The suspension of aroma frost particles in gaseous nitrogen is passed through a tubular porous filter to remove the aroma frost particles which collect on the outer surface of the tubular filter, with the nitrogen gas passing through the porus filter and being exhausted from the collector. The aroma particles recovered are suitable for incorporation in various food products where a natural cocoa or chocolate flavor is desired, including soluble cocoa products, cake mixes, confectionery products, and the like.
