Further, the apparatus comprises a first flow adjuster, inserted in the first fluid line for setting a volumetric or mass flow rate of the first fluid, and a second flow adjuster, inserted in the second fluid line for setting a volumetric or mass flow rate of the second fluid, as well as means for generating a first control signal, representing an instantaneous setting value for the first flow adjuster, and a second control signal, representing an instantaneous setting value for the second flow adjuster. To produce the fluid mixture, the first fluid and the second fluid are made to flow into the third fluid line alternately. The invention is particularly suited for mixing fluids having different viscosities.Type: GrantFiled: August 5, 2003Date of Patent: May 27, 2008Assignee: Endress + Hauser Flowtec AGInventor: Hartmut Breithaupt

Patent number: 7377686Abstract: The present invention uses one or more bags that are capable of being selectively pressurized and deflated in conjunction with a disposable bio bag such as a fermenter, mixing bag, storage bag and the like. The pressure bag(s) may surround a selected outer portion of the bag or may be contained within an inner portion of such a bag. By selectively pressurizing and deflating the pressure bag(s), one is able to achieve fluid motion in the bag thereby ensuring cell suspension, mixing and gas transfer within the bag without damaging shear forces or foam generation.Type: GrantFiled: April 7, 2004Date of Patent: May 27, 2008Assignee: Millipore CorporationInventor: John Dana Hubbard

Patent number: 7377687Abstract: A fluid temperature measurement probe, particularly for total temperature measurements in high temperature unsteady gas flows, such as in gas turbine engines. A pair of thin film resistance thermometers are deposited on the probe to sense its surface temperature at respective locations and the structure of the probe is configured such that the regions into which heat diffuses from the respective locations have different thermal products. In this way the thin film elements experience different heat transfer rates when exposed to the same fluid temperature. In one embodiment this is achieved by applying one of the elements to the surface of a solid rod of glass or ceramic and the other element to a portion which has been machined to leave an air pocket under a thin cylindrical wall of the rod material. In use the probe is exposed only temporarily to the high temperature fluid and withdrawn again before reaching its softening temperature.Type: GrantFiled: November 17, 2003Date of Patent: May 27, 2008Assignee: Qinetiq LimitedInventor: Kamaljit Singh Chana

Patent number: 7377689Abstract: According to one embodiment an apparatus to monitor the temperature of a transformer is disclosed. The apparatus includes a fiber optic cable having a temperature sensing probe on one end embedded in windings of a transformer. An optical converter transmits light to the probe and receives light from the probe, and converts the light received to an electrical signal. The light received back from the probe is controlled by temperature of the probe. Monitors are used to monitor different parameters of the transformer. A controller generates a simulated winding temperature based on data received from the monitors and converts the electrical signal to a direct winding temperature. The controller analyzes the operation of the transformer by comparing the direct winding temperature to the simulated winding temperature. Other embodiments are disclosed herein.Type: GrantFiled: August 31, 2005Date of Patent: May 27, 2008Assignee: Qualitrol CorporationInventor: Todd-Michael Balan

Patent number: 7377691Abstract: A radiographic apparatus obtains lag-free radiation detection signals with lag-behind parts removed from radiation detection signals taken from a flat panel X-ray detector as X rays are emitted from an X-ray tube. The lag-behind parts are removed by a recursive computation on an assumption that the lag-behind part included in each X-ray detection signal is due to an impulse response formed of exponential functions, N in number, with different attenuation time constants. X-ray images are created from the lag-free radiation detection signals.Type: GrantFiled: January 16, 2004Date of Patent: May 27, 2008Assignee: Shimadzu CorporationInventors: Shoichi Okamura, Keiichi Fujii, Susumu Adachi, Shinya Hirasawa, Toshinori Yoshimuta, Koichi Tanabe, Masatomo Kaino, Hiroshi Koyama
