Patent number: 6423124Abstract: The device for regulating a flow rate of an air-liquid centrifuge separator includes a gas outlet pipe, an outlet pipe for separated liquids and an inlet pipe through which a fluid to be separated enters the separator. The device includes a by-pass pipe, arranged between the liquid outlet pipe and the fluid inlet pipe, which removes liquid from the liquid outlet pipe and transfers it to the fluid inlet pipe when a pressure of the liquid in the liquid outlet pipe exceeds a predetermined level. The device is particularly useful in separators for dental aspiration plants.Type: GrantFiled: July 24, 2000Date of Patent: July 23, 2002Assignee: Cattani S.p.A.Inventor: Ennio Cattani

Patent number: 6368068Abstract: A system for controlling one or more borehole pumps includes a receiver/separator tank. The receiver/separator tank includes a body having a sealable top cap, an electronics panel, a separator housing, a separator cap that divides the electronics panel from the separator housing, and an inlet base at a second end of the body and dimensioned to maintain entry pipes in appropriate positions. The tank further includes a fluid outlet pipe; a gas pipe; a safety line; a supply line; an exhaust line; a propellant line; a fluid return line; and a spiral diffuser. The spiral diffuser is connected to the fluid return line to disperse fluid received through the return line at an angle to separate gas contained in the fluid. Pressure from the fluid causes the spiral diffuser to spin within the separator housing, and thus, separating gas contained within the fluid from the fluid.Type: GrantFiled: April 11, 2000Date of Patent: April 9, 2002Inventors: Edward A. Corlew, Henry B. Steen, III, John W. Smith

Publication number: 20020011151Abstract: An assembly is disclosed for an apparatus used for deaeration of treatment agents applied to webs of paper and board, the assembly comprising at least one inlet manifold (3), at least one accept-fraction manifold (4), and at least one reject-fraction manifold (5) with associated framework structures; also a method is disclosed for operating the assembly. For deaeration the assembly uses a plurality of air separator units (12) connected to the manifolds so as to allow admission of the treatment agent to the air separator units (12) from the inlet manifold (3) and discharge of the accept and reject fractions formed in the air separator units (12) respectively to the accept-fraction and reject-fraction manifolds (4, 5).Type: ApplicationFiled: July 10, 2001Publication date: January 31, 2002Applicant: Valmet-Raisio OyInventors: Martti Myrttinen, Ilkka Roitto

Patent number: 6336959Abstract: The invention is directed to an apparatus and method for feeding solution from a container with high accuracy. An embodiment of the apparatus is provided as a container hermetically containing a solution is made of a high polymer that permits the container to change its shape in accordance with the amount of its content. The container is removably connected to a tube for forming an isolated conduit extending from the container via a pump to the destination to which the solution is fed. The isolated conduit is provided with a gas-liquid separation tank for separating gas from the solution and a gas trap section communicating with the gas-liquid separation tank. The gas-liquid separation tank and the gas trap section are located between the container and the pump, and the gas trap section has a variable volume. Further, a desired number of isolated conduits may extend via respective pumps to the destination to which the solution is fed.Type: GrantFiled: December 13, 1999Date of Patent: January 8, 2002Assignee: Chugai Photo Chemical Co., LtdInventor: Hisao Kamo

Publication number: 20010054356Abstract: The invention provides an apparatus for conditioning a organic fluid for subsequent use in a medical procedure. The apparatus includes a cabinet having a secure environment and a door providing the only access to the environment. An input system is provided for transporting a organic fluid charge from a source to the cabinet and a container is removably contained in the secure environment and coupled to the charge input system to receive the charge. Stressors are coupled to the cabinet and positioned for operation to create a conditioned charge in the container. An output system is coupled to the container and includes a receiver for the conditioned charge. The apparatus includes an automated control system operable upon closing the door to lock the door and to then condition the charge, and to then cause the charge to move from the container to the receiver.Type: ApplicationFiled: March 16, 2001Publication date: December 27, 2001Inventors: Duncan Arthur Newman, Paul George Andrew Moore, Taras Worona
