Patent number: 10633798Abstract: Resin systems and methods for making and using same are provided. The method for making a paper product can include contacting a plurality of pulp fibers with a resin system. The resin system can include a first polyamidoamine-epihalohydrin resin and a second resin that can include a second polyamidoamine-epihalohydrin resin, a urea-formaldehyde resin, or a mixture thereof to produce a paper product. The first resin and the second resin can be sequentially or simultaneously contacted with the plurality of pulp fibers. The period for sequential addition between the first resin and the second resin is about 1 second to about 1 hour.Type: GrantFiled: December 4, 2017Date of Patent: April 28, 2020Assignee: ECOLAB USA INC.Inventors: Cornel Hagiopol, David F.

Patent number: 10301777Abstract: Wet strengthened fiber products, wet strengthening resins, and methods for making such wet strengthened fiber products and wet strengthening resins. The wet strengthened fiber product can include a fiber web and an at least partially cured wet strengthening resin, which prior to at least partially curing, the wet strengthening resin can include a polyamide-epihalohydrin (PAE) resin and a cationic styrene maleimide (SMI) resin. The PAE resin can include a reaction product of a polyamidoamine and an epihalohydrin and the cationic SMI resin can include a reaction product of a styrene maleic anhydride (SMA) copolymer and an amine. The wet strengthened fiber product can include the wet strengthening resin in an amount of about 0.05 wt % to about 5 wt %, based on a dried weight of the wet strengthened fiber product.Type: GrantFiled: June 27, 2017Date of Patent: May 28, 2019Assignee: ECOLAB USA INC.Inventors: Cornel Hagiopol, David F. Townsend, Clay E. Ringold, James W. Johnston

Patent number: 9907113Abstract: Provided is a system for wireless communications including several base stations supporting a wide area wireless network and several mobile user equipment (UE) devices. Each mobile UE device may be configured to transmit a request to establish a local wireless connection with one or more of the UE devices. The mobile UE device may receive a response containing connectivity information from each of the mobile UE devices and then select one of the mobile UE devices based on the connectivity information received from each of the mobile UE devices. The mobile UE device may then establish a local wireless connection with the selected mobile UE device. The mobile UE device may then communicate with one of the base stations in the wide area wireless network through the selected mobile UE device, utilizing the local wireless connection.Type: GrantFiled: May 10, 2012Date of Patent: February 27, 2018Assignee: INTEL CORPORATIONInventors: Marco Y.
