Abstract: A method of dissolving a rubber continuously to form a raw material for the production of rubber-modified polymer, by dissolving a rubber in a monomer liquid dissolving the rubber and capable of reacting with the rubber in the presence or absence of a solvent. Pieces of rubber are fed continuously to a dissolution tank to allow the dissolved rubber and the undissolved rubber to coexist in the dissolution tank, wherein the concentration of the dissolved rubber is the concentration at which the feeding to the reactor is made, and the quantity of the undissolved rubber present in the dissolution tank is at most the quantity that prevents pieces of the undissolved rubber from sticking to one another to form larger rubber masses. The time required for dissolution can be shortened, and the size of a dissolution tank can be made smaller, compared with the conventional methods.

Abstract: A lock-up control device is provided to control engaging force of a lock-up clutch, which shares engine output with a torque converter to transmit it toward an input shaft of a transmission. Herein, input shaft torque is estimated based on engine speed and engine intake negative pressure, while engine torque is estimated based on engine speed and throttle opening. A weight coefficient is produced based on an amount of variations of the engine torque when the amount of variations is greater than a prescribed value. Then, weighted mean engine torque is calculated by the input shaft torque and engine torque in accordance with the weight coefficient. Thus, the lock-up control device controls the lock-up clutch based on the weighted mean engine torque in such a way that the engaging force of the lock-up clutch is increased in response to the rise timing of the weighted mean engine torque. For example, the weight coefficient is determined in such a way that the engine torque is given high distributed weight in the weighted mean engine torque as compared with the input shaft torque. Thus, it is possible to increase the engaging force of the lock-up clutch promptly in response to the rise mode of the real engine torque, by which it is possible to avoid occurrence of control delay in control of the lock-up clutch.

Title: Process for treating wood
Inventor: MARCINKO JAMES L
IPC: B27K5/04
Filed: 1997-02-27
Granted: 2001-10-30
Abstract: A process for treating wood involving impregnation of the wood with a preservative followed by the heat-fixation of the preservative in the wood using a pre-heated aqueous heat tansfer fluid to effect the heat fixation of  the preservative. The process particularly relates to steps which are taken to reduce the level of any contamination of the aqueous heat transfer fluid resulting from any wood extractives, any unfixed preservative and/or any particulate matter (i.e. "sludge") that may be present in the fluid. The contamination is preferably reduced by incorporating in the heat transfer fluid an oxidant which will preferentially oxidize any wood extractives resulting from the contact of the treated wood with the fluid without any significant reaction occurring between the oxidant and the preservative. Useful oxidants include inorganic chlorate salts such as sodium chlorate.</S DOAB>

Abstract: An improved system and method for performing inversion and for correcting for shoulder bed effect. The method enhances the resolution of wave propagation resistivity logs and corrects the logs for adjacent bed effects, whereby the resulting logs have a vertical response as good as wireline high-resolution induction logs. The method first performs logging while drilling on a formation to obtain LWD resistivity log data. The method then selects one or more control depths at one or more locations of each of a plurality of detected beds in the formation. The present invention includes a novel method for selecting bed boundaries from the log data, and the control depths are then determined based on the determined bed boundaries. 1'he method then estimates the resistivity of each bed only at the selected control depths to produce an estimated resistivity of the beds. The method then computes a simulated log value at each control depth using a current estimate of the resistivity of the beds. The computed simulated log is then compared to the actual log data at each control depth, and the resistivity of each bed is adjusted using the difference between the actual and simulated values at the control depths. The above method iteratively repeats a plurality of times until the simulated log substantially matches the actual log at the control depths. The method for determining the bed boundaries in the formation preferably comprises fitting a cubic polynomial in depth to the conductivity, or log of the conductivity, using a weighted linear least-squares method. The curve fit of the log data is performed a plurality of times on portions of the log data using a windowing method. This windowing method comprises moving a window across the log data at periodic increments, and performing the curve fit on the window of log data at the periodic increments as the window is moved across the log data. The method then determines inflection points of the log data after the curve fit for each of the windows. The method then selects bed boundaries from the inflection points of the curve-fit of the log data.

Abstract: Tools for genetically engineering Pasteurellaceae are provided. Replication- conditional plasmids which are useful for the Pasteurellaceae have been isolated and characterized. The plasmids can be utilized for delivery of DNA segments into the Pasteurellaceae in situations where control of extrachromosomal replication desired, such as in achieving allelic exchange or site-directed mutagenesis. A restriction endonuclease, HsoI, was isolated from a bovine lung isolate of Haemophilus somnus. The enzyme was found to be a true isoschizomer of HinPI, a commercially available enzyme originally isolated from Haemophilus influenzae Pl. Commercially available HhaI methyl transferase was found to protect against cleavage by both enzymes. Methylation of foreign plasmid DNA was found to enhance transformation of Haemophilus somnus in excess of four orders of magnitude.< /SDOAB>

Title: Sheet feeder
Inventor: NORDLING MARK
IPC: B65H3/52
Filed: 1999-02-24
Granted: 2004-02-03
Abstract: An electromechanical friction feed device for controlling the single feed of sheet-like articles from a stack of such articles has a feed belt and stripper wheel that are used to draw a single article from the bottom of the stack to the discharge section of the feeder. The stripper wheels slowly rotate in a direction opposite to the feed movement to hold the penultimate sheet and those above it in a stack while the lowermost product is translated by the feed belt through the machine. The reverse rotation of the stripper wheel is accomplished using a dual ratchet mechanism along with unidirectional needle bearing assemblies that provide a smooth, continuous rotation of the stripper wheels. The two ratchet mechanisms are driven 180° out of phase with respect to one another to achieve the smooth continuous stripper wheel rotation. By using a dual ratchet mechanism instead of gears, the center distance between the feed belt drive shaft and the stripper wheel shaft can be adjusted to accommodate various product thicknesses. A discharge section of the friction feeder pulls the product from the feed belt and moves it at a higher velocity than that of the feed belt so as to provide separation between adjacent products being fed from the stack.
