Abstract: Mixed alkali metal salts of phosphoric acid in combination with a co-catalyst such as tetramethylammonium hydroxide (TMAH) are excellent transesterification catalysts for use in the preparation of polycarbonate from bisphenol A and diphenyl carbonate. The mixed alkali metal phosphate salts were shown by kinetic measurements made on a model system composed of p-tert-octylphenol and bis(p-cumylphenyl) carbonate to be inherently more potent catalysts than salts of phosphoric acid comprising a single alkali metal ion. In addition to providing higher rates of polymerization, the new catalysts were shown to provide polycarbonates containing reduced levels of Fries rearrangement product relative to polymerization reactions catalyzed by conventional catalyst systems such as sodium hydroxide together with TMAH co-catalyst.

Abstract: Siloxane bischloroformates are prepared in a continuous process by phosgenating siloxane bisphenols in a flow reactor using a substantial excess of phosgene and sodium hydroxide. While very high levels (>95%) of conversion of the siloxane bisphenol to the corresponding siloxane bischloroformate are achieved using a flow reactor according to the method of the invention, only more modest conversion (˜90%) of the siloxane bisphenol to the corresponding siloxane bischloroformate is attained when analogous batch processes are employed. The process holds promise for use in the manufacture of silicone-containing copolycarbonates which requires high purity siloxane bischloroformate intermediates.

Abstract: The present invention is directed toward providing interactive haptic collision detection between a stationary and a moving object in a virtual reality environment. A user grasps the arm of a haptic device and manipulates an object as viewed on a virtual reality display. As any portion of the manipulated object comes too close to the surface of the stationary object, the haptic device imposes feedback forces against the user's efforts that increase in magnitude as the user manipulates the object beyond a force boundary proximate to the surface of the stationary object. The feedback forces are applied directionally in line with the shortest path between the surfaces at risk of collision. Several measures can be implemented by the user to reduce the computation load involved in constantly comparing the distances between points on the surface of the movable object and points on the surface of the stationary object without seriously compromising the collision detection and avoidance functions of the system.
