Abstract: The invention relates to a process for the preparation of a copolyether ester built up of hard polyester segments of repeating units derived from at least one alkylene glycol and at least one aromatic dicarboxylic acid or an ester thereof and soft segments derived from at least one polyalkylene oxide glycol, which comprises polymerization by condensation in the melt of at least one aromatic dicarboxylic acid, at least one alkylene glycol and at least one polyalkylene oxide glycol, in the presence of a catalyst based on a combination of titanium and a bivalent metal in a single compound or several compounds, characterized in that the molecular ratio of Ti : bivalent metal is at most 1.6, preferably at most 1.5. The invention leads to a substantial shortening of the polycondensation time in the melt or a higher degree of polymerization of the copolyether ester. The solid-phase post-condensation can also be shortened substantially. The process is effective in particular for copolyether esters with a high soft segment content and for copolyether esters with soft segments based on polypropylene oxide glycol.

Title: Multi-variable processes
Inventor: BROOKS ROBIN WILLIAM
IPC: G01D7/02
Filed: 2000-11-27
Granted: 2011-02-08
Abstract: Control and output-quality variables of a process plant (1) are plotted against parallel axes in a display unit (7).  Convex hulls between pairs of variables are calculated from sets of the variable-values accumulated historically in stores (7, 9) during successive runs of the process, and hulls (H; TC, BC) between successive axis-pairs are displayed. New variable-values for process optimisation are fixed for the variables taken in turn, each selection being made within displayed ranges (Rn-Rn) derived from the hulls effective between the respective variable and the variables already fixed. A display unit (13) provides on-line parallel-axis display of variable-values from the plant (1) showing alarm carets (DC, UC) where values violate limits (UL, LL) determined by the convex hulls, and allowing variation in the displayed-value for observing the resultant effect in avoiding alarm situation and towards optimisation.

Abstract: Apparatus and a method for the evaporative cooling of a web (5) within a dry er in a compact manner. Excess fluid overspray is controlled, thereby avoiding problems with fluid depositing on internal surfaces of the dryer, which can cause mineral build-up and can result in web breaks or quality defects if fluid drips onto the web. More specifically, a water delivery system (15) is used which directs a water mist to the web by appropriate design and placement of the spray nozzles (18). The quantity of water delivered to the web is regulated, and is preferably based upon web temperature. Excess mist is controlled by directing hot air to effectively vaporize the excess mist before it is able to contact the internal surfaces of the dryer enclosure (10) and its internal components.

Abstract: A power system specifically designed to provide reliable electrical power to a telecommunication facility is disclosed. The system includes a number of microturbine generators adapted to provide AC power that is then rectified to DC power by an array of rectifiers. The system is configured so that the microturbine generators are fueled initially by utility-supplied natural gas. In the event the utility-supplied natural gas fails, the system provides propane from a storage tank to fuel the microturbine generators. If both microturbine generator fuel sources fail or their fuel supply becomes exhausted, power is supplied to the rectifiers by a commercial electrical utility. The system also includes a number of hydrogen-powered proton exchange membranes that are operable to supply DC power directly to the facility if both the microturbine generators and the electrical utility fail. Finally, a number of super capacitors are coupled to the bus line directly connected to the facility in order to maintain power if it becomes necessary to switch power sources.
