Abstract: An improved vision system is provided for identifying and assessing features of an article. Systems are provided for developing feature assessment programs, which, when deployed, may inspect parts and/or provide position information for guiding automated manipulation of such parts. The improved system is easy to use and facilitates the development of versatile and flexible article assessment programs. In one aspect, the system comprises a set of step tools from which a set of step objects is instantiated. The set of step tools may comprise machine vision step objects that comprise routines for processing an image of the article to provide article feature information. A control flow data structure and a data flow data structure may each be provided. The control flow data structure charts a flow of control among the step objects.

Abstract: Metal working compositions which contain rhamsan gum as a mist suppressant exhibit good anti-mist performance and good retention of performance in the presence of prolonged times of shearing.

Abstract: Electrorheological fluids of a hydrophobic liquid phase and, dispersed therein, electrorheologically active particles comprising a core particle and a coating of a metal carbonate, sulfate, thiosulfate, or sulfite exhibit reduced electrical conductivity compared with similar fluids containing uncoated particles.

Abstract: The invention concerns a method of using constrained layer sound damping. A composition and a laminated structure are provided for the reduction of noise coming from housings such as oil pans for automobiles. The composition comprises a rubbery polyurethane, an olefin polymer, and a filler. The laminated structure comprises the housing, the composition, and a sheet metal liner. The composition contains a blowing agent which is activated to provide a single unitary structure which dampens noise. The polyurethane and olefin polymer are thoroughly intermixed with each other, but maintain their separate identities in the blend.
