Title: Process for treating sludge
Inventor: MIURA NOBUYOSHI
IPC: B01F25/60
Filed: 2002-02-07
Abstract: A process for treating sludge is disclosed. Sludge to which a flocculating agent has been added is stirred by a stirring pump or shear-stirred by a liquid shear-stirrer prior to initiation of flocculation reaction of the flocculating agent to render the flocculating agent in a fine particulate state to thereby disperse, diffuse or distribute the flocculating agent in a fine particulate state throughout the sludge, so that flocks or aggregate structure type flocks or blocks can be efficiently formed. A treating line is constructed such that the sludge can flow therein as a laminar flow. The distance from a flocculating agent injection part to a stirring pump is made to a distance such that the flocculating agent can pass through in a reaction initiation time obtained in advance for the flocculating agent. The time at which flocculation strength of flocks formed by the flocculation reaction of the flocculating agent is maximal is experimentally confirmed in advance and a solid-liquid separator is set at a position where at such time the flocks can reside by the solid-liquid separator.

Title: Cloning, expression, sequencing, and functional enhancement of monoclonal scfv antibody against venezuelan equine encephalitis virus(vee)
Inventor: FULTON R ELAINE
IPC: C07K16/10
Filed: 2002-03-08
Abstract: The invention discloses generation of a single chain variable fragment (ScFv) antibody from a well-characterized monoclonal antibody (Mab) against Venezuelan equine encephalitis (VEE) virus, by cloning variable regions of the heavy (V  H) and the light (V L) chain antibody genes, connected by a DNA linker, in phagemid expression vector pCANTAB 5 E. Mab clone 1A4A1 was successfully cloned as ScFv in Escherichia colt strain TG-1 and expressed as a ~.about.30 KDa ScFv protein which was functional in recognizing VEE by ELISA. Results were reproduced in Escherichia coli strain HB2151, where the same clone, designated A116, was expressed mainly as soluble periplasmic protein. The 30 KDa A116 displayed weak binding specificity to VEE. Sequence analysis revealed a frame shift in the N-terminal region of the V L  domain, upstream to the complementarity-determining region 1, as the probable cause of reduced activity. A PCR-based site-directed mutagenesis approach was adopted to re-introduce the three single-base deletions in the 5 prime region of the V L gene of A116, corresponding to framework-1 region. The mutagenized A116 was designated as MA116. The introduction of these three bases corrected a localized frame-shift in framework-1 region to consensus framework-1 amino acid sequence. Five MA116 clones (MA116-4, MA116-6, MA116-14, MA116-15, and MA116-16) have been analyzed for their reactivity to VEE antigen, with MA116-15 showing comparable reactivity to the parental 1A4A-1 Mab in recognizing VEE antigen. Sequence data revealed that only MA116-15 had incorporated the three intended base insertions without accumulating any other mutational changes.

Title: Semiconductor and manufacturing method for semiconductor
Inventor: SJODIN HAKAN
IPC: H01L21/331
Filed: 2000-06-21
Abstract: A semiconductor component comprising a highly doped layer on a substrate layer and delimited by at least one trench extending from the surface of the component through the highly doped layer, also comprises a sub-layer between the substrate layer and the highly doped layer, said sub-layer being doped with the same type of dopant as the buried collector, but to a lower concentration. A method for manufacturing such a component is also disclosed.  The sub-layer causes a more even distribution of the potential lines in the substrate and in the subcollector layer, thereby avoiding areas of particularly dense potential lines. Since the breakdown voltage is lower in areas with dense potential lines, avoiding too dense potential lines means increasing the breakdown voltage of the component.

Abstract: A blood viscosity measuring system and methods for measuring blood viscosity monitors the change in height of two, oppositely-moving, columns of blood from the circulating blood of a patient and, given the dimensions of a capillary tube through which the blood flows, determines the blood viscosity over a range of shears, especially low shears.      The system includes a tube set (disposable or non-disposable) that includes a pair of riser tubes, a capillary tube of predetermined dimensions that is coupled between the riser tubes (or that forms a portion of one riser tube) and a valve mechanism for controlling the circulating flow of blood from the patient into the riser tubes. Respective sensors monitor the movement of the columns of blood in each of the riser tubes and an associated microprocessor analyzes these movements, along with the predetermined dimensions of the capillary tube to determine the viscosity of the patient's circulating blood. An alternative system and method monitors only one of the two oppositely moving columns while detecting a single height position of the other one of the moving columns. From that data, along with the dimensions of a capillary tube through which the blood flows, the blood viscosity over a range of shears, especially low shears, is determined.

Title: Visible-near infrared spectroscopy in burn injury assessment
Inventor: PAYETTE JERI
IPC: A61B5/00
Filed: 2001-01-26
Abstract: A non-invasive method of characterizing burn injuries using near infrared spectroscopy is described. In the method, a beam of light is emitted into th e burnt tissue portion at two or more different tissue depths. The spectra are  then compared using multivariate analysis to determine diagnostic regions of  the spectra. This information is used to categorize the burn. In some cases,  the diagnostic regions correspond to wavelengths related to the hemodynamics  of the tissue portion. The spectra can also be repeated over time, thereby allowing trends and changes in the spectra to be measured. This data is in turn used to categorize the burn as either a superficial burn, partial thickness burn, deep partial burn or a full thickness burn. Once the burn ha s been categorized, the clinician can intervene as needed to treat the burn.</ SDOAB>

Title: System for continuous wave rejection
Inventor: SEZGIN NADIR
IPC: H04B1/7115
Filed: 2000-02-04
Abstract: A method is disclosed for receiving transmitted signals in the presence of CW  interference in a communication system that determines the presence of a code in a received signal by comparing with a detector threshold calculations made in accordance with a sample of a received signal. Such systems include but are not limited to those incorporating a Sequential Probability Ratio Test. The method includes obtaining a first input power value of the received signal at a first sample time and obtaining a second input power value of the received signal at a second sample time. The first and second power values are compared in order to provide an input sample comparison and the forgoing steps are repeated in order to provide a plurality of input sample comparisons. The detector threshold is adjusted in accordance with the plurality of sample comparisons. The CW signal can be strongly correlated with a short code used for the acquisition purposes. Therefore in the CDMA systems if the received signal contains a CW signal, then the strong correlation between the CW signal and the short code used for acquisition may result in a false alarm. To prevent this, the following algorithm is suggested to be used for the cancellation of CW, if there is a CW signal present in the received CDMA  signal.

Inventor: HEIDT GUNTHER
IPC: F16J15/32
Filed: 2001-03-22
Abstract: A contaminant pressure responsive, lubricant pressure amplified or modified rotary seal cartridge for rotary well pumps and other rotary mechanisms. A  housing member having a passage subject to contaminant pressure, has a rotary wear sleeve which is supported by bearings and is sealed to the housing by a plurality of spaced seals which define at least one and preferably two or more lubricant chambers for bearing lubrication and for hydrodynamic sealing.  Lubricant pressure amplification cylinders are in fluid communication with respective lubricant chambers. Pistons moveable within each of the cylinders define differential surface areas exposed to lubricant and to contaminant pressure. Contaminant pressure acts on the pistons and develops lubricant pressure which is different, preferably higher, but can be lower than contaminant pressure. When lubricant pressure is higher than contaminant pressure it acts directionally toward contaminant pressure or environment pressure to minimize the potential for contaminant intrusion into the lubricant chambers and also enhances the hydrodynamic wedging of the lubricant into the dynamic sealing interface between the seals and the rotary member for enhanced service life of the seals even under high pressure conditions.
