20080262119 | PROCESS FOR PREPARING POLYMER POLYOLS - The invention relates to a process for the batch or semi-batch preparation of a polymer polyol, which process comprises mixing a base polyol, one or more ethylenically unsaturated monomers, a polymerization initiator, optionally a macromer, and optionally a chain transfer agent, and polymerizing the mixture thus obtained at a temperature of 50 to 200° C., wherein one or more of the compounds to be mixed are fed while having a temperature that is higher than ambient temperature. | 10-23-2008 |
20120184707 | PROCESS FOR PREPARING A POLYMER POLYOL - The invention relates to a process for preparing a polymer polyol, comprising mixing in a reactor vessel, a base polyol, one or more ethylenically unsaturated monomers, a polymerization initiator, optionally a macromer, and optionally a chain transfer agent, and polymerizing the mixture thus obtained at a temperature of 50 to 200° C., wherein after discharging the reactor vessel content, the interior surface of the reactor vessel walls and/or any internals present in the reactor vessel are blasted with round media. | 07-19-2012 |
20130131205 | PROCESS FOR PREPARING POLYMER POLYOLS - The invention relates to a process for the preparation of a polymer polyol which is at most 60 wt. %, which process comprises mixing a base polyol, one or more ethylenically unsaturated monomers, a polymerization initiator, optionally a macromer, and optionally a chain transfer agent, and polymerizing the mixture thus obtained at a temperature of 50 to 200° C., optionally below 120 C, wherein the initiator is of formula R | 05-23-2013 |

20150123968 | OCCLUSION RENDER MECHANISM FOR POINT CLOUDS - A method, apparatus, system, article of manufacture, and computer readable storage medium provide the ability to render point cloud data. After obtaining point cloud data, polygons are fit to the point cloud data. A texture atlas is created for each of the polygons. A lookup table is generated from the texture atlases and maps each pixel to a corresponding texture location. When a scene is loaded for rendering/processing, the polygons and texture atlas are loaded and projected into an off-screen buffer that defines a depth map of the scene with approximations of a depth per pixel in screen space. The off-screen buffer is used as a lookup table to determine texture data to be rendered for the scene. | 05-07-2015 |
