Publication number: 20030230193Abstract: This disclosure relates to a method for deaerating a liquid layer such as a coating solution using electrostatic forces. A flow of charged particles is created above and moved towards a low conductivity liquid layer. The flow of charged particles causes localized thinning of the liquid layer which facilitates the removal of bubbles of entrained gas from the liquid by bringing those bubbles closer to the exposed surface of the liquid and rupturing them at that surface. This electrostatic deaeration technique is combined with other non-electrostatic liquid layer thinning techniques or degassing techniques to further facilitate removal of bubbles from the liquid in preparation of further processing of the liquid. The liquid layer may be stationary or flowing with respect to the application of charge particles.Type: ApplicationFiled: June 18, 2002Publication date: December 18, 2003Inventors: John W.

Patent number: 6053967Abstract: An air separator for liquid containing gas bubbles having an essentially cylinder-shaped chamber through which liquid, such as blood, flows essentially in helical flow paths, with the result that air bubbles are driven in a radial direction relative to the longitudinal axis of the chamber because of pressure differences produced by centrifugal forces. The inlet and outlet of the chamber of the air separator are coaxial relative to each other in the longitudinal axis of the chamber. The air separator also includes a flow-deflection component or influx distributor, which includes a rotation-symmetrical base body element whose outer surface faces inflowing liquid as a first deflection surface, which is geometrically defined by rotation of a curve section about the longitudinal axis of the chamber.Type: GrantFiled: August 25, 1994Date of Patent: April 25, 2000Assignee: Fresenius AGInventors: Klaus Heilmann, Bernd Knierbein

Patent number: 6042635Abstract: A method for wetting a filter element by a high viscosity liquid and an apparatus for practicing such method are provided. In the method, a sealable container that is equipped with a vibration device and is capable of holding a pressurized liquid therein is used. The vibration device creates a vibration in the pressurized liquid such that trapped air bubbles in the filter element are separated from the filter element and are exhausted. The method and apparatus can be used for pre-wetting any filter element in any type of liquid, either of the high viscosity type or of the low viscosity type, even though it is particularly suitable for wetting a filter element by a high viscosity liquid and removing trapped air bubbles in the filter element.Type: GrantFiled: June 4, 1998Date of Patent: March 28, 2000Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: W.

Patent number: 5958108Abstract: Apparatus and methods for separating fluids of differing specific gravities are discussed. More specifically, apparatus and methods for separating a high volume flow mixture of air and water into an essentially dry air component and a pure water component are discussed. The separator is high volume and is structured around three physical elements which are defined as an input, a water chamber and an air separator chamber. A composite flow enters the input where most of the heavier water component separates, under the force of gravity, and flows into the water chamber. The remaining fluid, which is air and water in the form of vapor, mist, or droplets, is drawn into the air separator chamber using a vacuum pump, and subsequently flows through a condensate sub chamber which physically is an element of the air separator chamber. Any moisture in this flow is condensed within, and drained from, the condensate chamber such that dry air is discharged from the air separator chamber.Type: GrantFiled: April 23, 1998Date of Patent: September 28, 1999Inventor: Thomas J.

Patent number: 5674199Abstract: An apparatus for trapping bubbles in blood flowing in a circuit, such as blood in an extracorporeal circuit, is provided. The apparatus includes a housing which defines a substantially vertical chamber. Blood is introduced into the chamber through an inlet tube extending downwardly into the chamber and is removed from the chamber at an exit port near the lower end of the housing. A diverter having a container base and rim is positioned within the chamber. Blood is introduced near the container base. The blood is redirected upward upon contact with the container base and is then redirected downward over the rim. The redirection of blood flow provides an opportunity for bubbles in the blood to separate from the blood in the chamber and also helps prevent stagnation of blood in the chamber which might otherwise lead to clotting and separation of the blood.Blood is introduced into a chamber of the apparatus in a generally downward direction below the level of blood already present in the chamber.Type: GrantFiled: September 21, 1995Date of Patent: October 7, 1997Assignee: Cobe Laboratories, Inc.Inventor: James Myron Brugger
