  • Publication number: 20190292090
    Abstract: A furnace system includes a muffle defining a furnace cavity. A lower heater is coupled to the muffle and is configured to create a hot zone within the furnace cavity having a temperature of about 1900° C. or greater. An upper muffle extension is positioned above the muffle and defines a handle cavity. A downfeed handle is positioned within the handle cavity such that a gap is defined between an outer surface of the downfeed handle and an inner surface of the upper muffle extension. An upper heater is thermally coupled to the upper muffle extension and configured to heat the gap. A gas screen is positioned in the upper muffle extension and is configured to inject a process gas into the handle cavity.

  • Publication number: 20180176193
    Abstract: A computing resource service provider may operate a secure proxy fleet within a content delivery network. The secure proxy fleet may protect sensitive data communicated between a client device and a backend service over one or more networks, for example, over the content delivery network to a computing resource service provider environment. The secure proxy fleet may protect sensitive data by encrypting the sensitive data before it is forwarded to a destination.

  • Publication number: 20170316437
    Abstract: Disclosed are various embodiments for predicting and classifying events that create a sudden or substantial increase in network traffic activity. To begin, an increase of network activity can be detected. Upon detecting the increase in network activity, it can be determined that the increase in network activity is unexpected in view of one or more predicted activity events. The system can be adjusted to reduce the network activity in response to determining that the increase in network activity is unexpected.

  • Patent number: 9727882
    Abstract: Disclosed are various embodiments for predicting and classifying events that create a sudden and substantial increase in network traffic activity. To begin, a sales event may be predicted based on the results following the search for one or more prediction factors that occur during a predefined period of time. Based either on the individual results of each evaluation or a combination of results of the search of two or more of the prediction factors, a sales event may be predicted. Additionally, upon detection of a sudden and substantial increase in network traffic activity, one or more classification factors may be evaluated to determine whether the cause of the increase is due to a sales event or other type of alternative activity event.

  • Publication number: 20160371614
    Abstract: A framework enables the automated and coherent analysis of the management of resources. Such resources may include impact resources. As such, the framework provides an integrated overview of various impacts of a resource portfolio, resource fund, manager of a fund, or other resource management instrument. The framework generates detailed reports at the portfolio, fund, manager, or firm levels. The reports provide an overview and a robust data set of metrics, scores, and other analytics regarding the impact of a particular resource management thesis, including at least an impact strategy score and an execution risk score. By determining a quantified and standardized measurement of the social and/or environmental benefits or impacts of various resource management instruments, the framework provides a user an aggregated overview of the various impacts at both the level of user's portfolio and the various funds, managers, or firms that the user holds within their portfolio.

  • Publication number: 20080000603
    Abstract: Methods are provided for creating covalent bonding of webs by combining cellulosic fibers having a carboxyl content approximately greater than 7 meq/100 g with one or more crosslinking agents. In a first step, a carboxyl group is placed onto a fiber. In an embodiment, the fiber is then reacted with an oxazoline-functional polymer which has been combined with a polycarboxylate compound. Heat is applied to the treated web, and this enables formation of a cross-linked bridge in the form of a covalent bond. In an embodiment, the covalent bonding of the carboxylated cellulose pulp webs utilizes oxazoline-functional polymers and polyacrylic acid. The oxazoline polymer in combination with polyacrylic acid should form a network polymer with covalent bonds to the cellulose carboxyl groups. The non-woven web may be strengthhened by covalent bonding, thereby improving overall wet/dry strength of the final product.

  • Patent number: 7300546
    Abstract: A cellulose fiber having extended biostability and the method of its manufacture are described. While prior treatments of cellulose with biotoxic metal compounds have given improved resistance to decay, these treatments have not been entirely satisfactory where the fiber had to be refined before use. Refining energy was very high and fiber length loss was substantial. Treatment of cellulose fiber with dideyldimethylammonium chloride (DDAC) or bromide (DDAB), these materials in combination with low levels of copper, or low levels of copper alone, has given a product with very good biostability without a major increase in refining energy or loss of fiber length. The treated fiber is particularly advantageous as a reinforcing component for cement board products.

  • Patent number: 7135557
    Abstract: A method of making a carboxylated carbohydrate is disclosed, cellulose being a preferred carbohydrate material. Carboxylated cellulose fibers can be produced whose fiber strength and degree of polymerization is not significantly sacrificed. The method involves the use of a catalytic amount of a hindered cyclic oxammonium compounds as a primary oxidant and chlorine dioxide as a secondary oxidant in an aqueous environment. The oxammonium compounds may be formed in situ from their corresponding amine, hydroxylamine, or nitroxyl compounds. The oxidized cellulose may be stabilized against D.P. loss and color reversion by further treatment with an oxidant such as sodium chlorite or a chlorine dioxide/hydrogen peroxide mixture. Alternatively it may be treated with a reducing agent such as sodium borohydride. In the case of cellulose the method results in a high percentage of carboxyl groups located at the fiber surface.
