20080196841 | WATER-BASED PRECIPITATION OF POLYMER SOLUTIONS - A solid polymer is recovered from a solution by the addition of a water-based solution containing a surfactant. The solutions are mixed and heated, so that the organic solvent containing the polymer is driven off, and the solid polymer can be recovered. The solid polymer is generally recovered in the form of small particles, which can be easily moved, as part of a slurry, and then dried. The process produces no hazardous waste. The by-products of the process can be re-used or discarded through ordinary channels. | 08-21-2008 |

The composition is a spin dope including tetrabromo bis-phenol A polycarbonate (TBBA-PC) and tetrabromo bishydroxyphenylfluorene polycarbonate (TBBHPF-PC), in proportions, by weight, ranging (in percent) from about 60/40 to 40/60, and n-methyl pyrrolidinone (NMP) and triethylene glycol (TEG), wherein the ratio of the amounts of NMP to TEG, by weight, is in the range of about 1.6-2.5.

20140291887 | METHOD FOR MAKING GAS-SEPARATION MEMBRANES HAVING IMPROVED FLUX AND SELECTIVITY - A polymeric fiber for use in gas separation is formed from a spin dope which includes solvent and non-solvent materials. The fiber is passed through a quench bath, and then a leach bath, in which the solvent and non-solvent are removed. The quench bath and the leach bath include sets of rollers which transport the fiber through the system. Each set of rollers in the leach bath operates at a speed which is greater than or equal to the speed of the rollers which are immediately upstream. Thus, the fiber is stretched, in different amounts, at the same time that the solvent and non-solvent are being removed, and while the fiber is still wet. The resulting fiber has been found to exhibit superior flux and selectivity properties. | 10-02-2014 |
20160038887 | POLYSULFONE MEMBRANE HAVING HIGH SELECTIVITY - A spin dope composition produces a polymeric fiber useful in non-cryogenic gas separation. The composition includes polysulfone as the polymeric component, two solvents, in which the polymer is soluble, and a non-solvent, in which the polymer is insoluble. The solvents preferably include N-methyl-pyrrolidone (NMP) and N,N-dimethyl acetamide (DMAC), and the non-solvent preferably includes triethylene glycol (TEG). Fibers made from the present composition have been found to exhibit superior properties of gas flux and selectivity, as compared with fibers made from spin dopes having only one solvent component. | 02-11-2016 |

An action planning module selects a next action of the robot. The marker generator module generates and outputs the marker commands to the simulator module in response to the selected next action. The GUI receives and displays the visual markers, selected future action, and input commands. Via the action planning module, the position and/or orientation of the visual markers are modified in real time to change the operation of the robot. | 08-27-2015 |
