20080236770 | RAPID FATTY ACID ASSAY FOR USE IN PULP PITCH CONTROL - Methods are provided for determining the surface fatty acid content in a wood pulp or whitewater sample. The methods comprise reacting free fatty acids which are present on the surface of the wood pulp fibers in the sample or in the whitewater with one or more reagents to form a measurable species, and determining the fatty acid content from the quantitative measurement of the measurable species. The method is useful as a quick, portable, accurate and low cost assay for assessing the fatty acid content present at various sample points in pulp and paper mills. The method for determining the free fatty acid content can be conducted in a batch process (e.g., where samples are collected periodically and the test is conducted offline). Alternatively, the method for determining the free fatty acid content can be conducted in a continuous or semi-continuous process (e.g., online sampling/analysis). | 10-02-2008 |
20100170646 | METHOD OF INCREASING ENZYME STABILITY AND ACTIVITY FOR PULP AND PAPER PRODUCTION - Wood pulp is treated with an esterase formulation in combination with a metal ion or cationic polymer to increase the stability or activity or both of esterase enzymes at high temperature, or at extreme pH ranges of acidic and alkaline conditions. The treatment by esterase together with metals ion or cationic polymer can be used to treat pitch containing pulp at high temperatures prior to, during or after refining of wood chip/pulp, in order to enhance the reduction of pitch problems and facilitate in the manufacture of paper. | 07-08-2010 |
20100269989 | USE OF 1,3-SELECTIVE LIPASES FOR PITCH CONTROL IN PULP AND PAPER PROCESSES - Formulations for pitch control, and methods of making and using thereof, are described herein. The formulations contains one or more 1,3-selective lipases. 1,3-selective lipases catalyze the hydrolysis of the terminal ester groups in triglycerides leaving the internal ester group intact. The enzyme formulations can contain one or more additives, such as dispersants, metal ions, absorbents, adsorbents, cationic polymers, and combinations thereof. The enzyme formulation is typically applied as a solution to the pulp stock. The enzyme formulations can be applied at any of one or more various points during the pulping and paper manufacturing processes. The use of selective lipase(s) decreases the total concentration of fatty acids in the system, and catalyzes the formation of monoglycerides, which are more effective at dispersing fatty acids than glycerol, the product of non-selective lipases, thereby improving pulp and paper machine runnability and pulp and paper quality. | 10-28-2010 |

The pulps to be treated include mechanical, chemical, semi-chemical pulps; sulfide pulp; recycled old newspapers; mixed office wastes; corrugated boxes; and their combinations. The use of water soluble aminoplast ether copolymers to control or prevent pitch and stickies deposition improves down stream performance of papermaking equipment increasing mill efficiency and improving paper quality. | 04-28-2011 |
20150136343 | Enzymatic Treatment of Virgin Fiber and Recycled Paper to Reduce Residual Mineral Oil Levels for Paper Production - Compositions comprising enzyme compositions are provided. Also provided are methods of treating virgin fiber and recycled wastepaper containing mineral oils using the compositions comprising enzyme compositions. The mineral oils generally originate from wastepapers with mineral oil based inks and certain other hydrocarbon-based chemistries used during the manufacturing, paperboard converting, and packaging process. The enzymes break down or modify mineral oils present in the fiber and paper, mobilize and liberate them from the fibers, and increase removal of mineral oils during paper recycling, pulping and papermaking processes. The method results in the break down or modification of mineral oil components in wastepaper, recycled pulp, and paper products by the enzyme compositions so that the mineral oils can be more efficiently detached and removed. The resulting pulp and paper has much reduced mineral oil concentration or less problematic forms of mineral oils and is beneficial for making food packaging paper products. | 05-21-2015 |
20150267349 | Method of Increasing Enzyme Stability and Activity for Pulp and Paper Production - Wood pulp is treated with an esterase formulation in combination with a metal ion or cationic polymer to increase the stability or activity or both of esterase enzymes at high temperature, or at extreme pH ranges of acidic and alkaline conditions. The treatment by esterase together with metals ion or cationic polymer can be used to treat pitch containing pulp at high temperatures prior to, during or after refining of wood chip/pulp, in order to enhance the reduction of pitch problems and facilitate in the manufacture of paper. | 09-24-2015 |

20080240447 | SYSTEM AND METHOD FOR USER AUTHENTICATION WITH EXPOSED AND HIDDEN KEYS - The present invention relates to a system and method for digitally authenticating users both online and offline. In one embodiment, a hardware token assigned by a trusted token provider to the user is employed to ensure the identity of the user. In the online authentication, the token is adapted for generating an exposed key EK and a hidden key HK based on a noise code NC and a time code TC of the token, a space code SC of a service server, and an owner code OC of the user. A login session is initialized by entering a user identifier at the service server and the generated EK from a computing device. The service server computes an expose key CEK and a hidden key CHK based one an authentication license generated by the token provider. The service server authenticates the user if the CEK is same as the EK, and sends a response message encrypted the CHK to the computing device. Then, the user provides the HK to the computing device to decrypt the encrypted response message so as to access his/her account. In the offline authentication, the token is adapted for generating a license exposed key LEK used to render the encrypted digital content on an offline compliant device. The compliant device authenticates the user if a license exposed key computed by the compliant device based on a content license of which the user bought is same as LEK, so as to render the protected digital content after authentication. | 10-02-2008 |
20090044013 | Systems and Methods for Preventing Spam - Systems and methods are disclosed for preventing spam, including email spam and telephone spam, through the use of dynamic passcodes or dynamic signatures included with transmitted messages. Both the dynamic passcodes and dynamic signatures may be changed periodically or continually, according to an example embodiment of the invention. Qualified senders may include a dynamic signature that is automatically generated by the sender's node or exchange entity. The recipient's node or exchange entity can then use a graylist associated with the recipient account in verifying the qualified sender and/or dynamic signature. On the other hand, non-qualified senders may need to manually obtain a dynamic passcode from a dynamic passcode provider and include the dynamic passcode with the transmitted message. The dynamic passcode provider may be a public website using human interactive proofs. According to an embodiment, a non-qualified sender may be optionally pre-charged with a fee to obtain a dynamic passcode. The recipient of the message may then refund the charge if the received message is not spam. | 02-12-2009 |

20110143094 | Process for Forming High Surface Area Embedded Coating with High Abrasion Resistance - The process of the present invention significantly increases the durability of superhydrophobic surfaces, while retaining similar optical properties to those of the original surface. The process uses velocity and heat to take freshly formed nano- and ultrafine particles and can partially embed and chemically bond them to the substrate, creating a strongly bonded nano-to-submicron textured surface. This nanotextured surface can then be modified to have desirable surface properties; for example, it can be hydrophobic, oliophobic, or hydrophilic. The high points of the coating made with this process protect the remainder of the surface from abrasion, thus greatly increasing product life in many uses. In preferred embodiments, the process is used to coat transportation vehicle windshields. | 06-16-2011 |
