Title: Continuous preparation of low unsaturation polyoxyalkylene polyether polyols with continuous addition of starter
Inventor: SHIH T THOMAS
IPC: C08G65/10
Filed: 1997-07-12
Granted: 2006-10-10
Abstract: A continuous process for the preparation of polyoxyalkylene polyethers using DMC catalysts as the polyoxyalkylation catalyst employs continuous addition of alkylene oxide in conjunction with continuous additio n of starter and catalyst to a continuous oxyalkylation reactor. Despite the continuous introduction of starter, the molecular weight distribution of the polyether product is quite narrow, as indicated by the exceptionally low polydispersity of the product. The presence of low molecul ar weight species during the majority of the polyoxyalkylation also substantially eliminates extremely high molecular weight fractions havi ng molecular weights greater than 100,000 Da, again without appreciably broadening molecular weight distribution. By withdrawing intermediate molecular weight polyether product or diverting a portion of the end product to prepare a catalyst/starter mixture, rapid and sustained reaction rates can be achieved while employing low molecular weight starters. Continuous build ratios in excess of 0.98 can be achieved.
Patent CA-2255786-C (CA)
Inventor: VALABH RAJESH
IPC: H02K7/18
Filed: 1998-12-14
Granted: 2002-08-27
Abstract: The present invention includes a dual purpose carbonator/blending bottle connected to a source of beverage syrup, a source of potable water and to a source of pressurized carbon dioxide gas. The dual purpose bottle is retained within an ice bank water bath tank. A pair of ratio valves provide for metering the water and syrup at a desired ratio. The mixed beverage first flows through a serpentine coil, also located in water bath, and then flow into the dual purpose bottle. A refrigeration system provides for cooling an evaporator located in the water tank for forming the ice bank thereon. The carbonated beverage then flows from the bottle into a freeze cylinder. The freeze cylinder also includes a further evaporator coiled around an exterior perimeter thereof. The freeze cylinder evaporator is connected to and cooled by the same refrigeration system that cools the evaporator in the water bath tank. A scraping mechanism within the cylinder provides for scraping frozen beverage from the inner surface of the cylinder.  A control mechanism provides for controlling the refrigeration system and the cooling of both evaporators. The beverage is therefore pre-cooled to a temperature just above its freezing point before delivery to the freeze cylinder. Thus, less cooling power is needed to reduce the beverage to a frozen state. The present invention utilizes a method of controlling the operation of the refrigeration system and the cooling of both evaporators thereof. The control system provides for directing refrigerant to one or the other of the evaporators as is most efficient so as to avoid short cycling or pressure build up. The present invention uses a control strategy that can more accurately maintain a pre-selected temperature differential between the inlet and outlet temperatures of the evaporators. The control algorithm utilizes a proportional integral differential control approach that safely permits a much narrower temperature difference so that a greater length of each freeze cylinder evaporator can be utilized for efficient heat transfer cooling.

Abstract: A leak sensor system for use in liquid processing equipment is disclosed. Liquid is detected by a sensing resistor whose impedance decreases dramatically in the presence of liquid. The effect of this impedance drop on the output voltage of the sensor indicates a wet or moist state which may indicate leakage from the liquid processing. A terminal resistor is in the circuit beyond the sensing resistor to provide a warning indicator when the sensing resistor is damaged or disconnected. The leak sensor system is particularly useful in centrifuge equipment, e.g., for the processing of blood.
