Patent number: 10844229Abstract: Radiation-curable, polyester acrylate-containing compositions (I) obtainable by reacting 0.5 to 20 mol % of a polyester polyol (A) and 0.5 to 30 mol % of a polyester diol (B) with 1 to 10 mol % of phthalic anhydride (C) and 65 to 75 mol % of (meth)acrylic acid (D) in the presence of an acidic esterification catalyst, a hydrocarbon (L), and a polymerization inhibitor. Reaction temperatures range from 60 to 140° C. The hydrocarbon (L) functions as solvent, forms an azeotropic mixture with water, and is removed distillatively after esterification. Water formed in the reaction is removed azeotropically. After neutralization of the esterification catalyst, free (meth)acrylic acid is reacted with an epoxide compound (E) in an amount equivalent to the acid number of the reaction mixture. The compound (E) has at least two epoxide groups per molecule. The compositions are suitable for coating the surfaces of solid substrates.Type: GrantFiled: October 2, 2017Date of Patent: November 24, 2020Assignee: BASF SEInventors: Delphine Kimpel, Kenneth Shaun Tranter, Daniel Kunz, Kathrin Cohen, Peter Thuery, Christine Roesch, Stefan Wahl

Patent number: 8850239Abstract: The network computing cluster includes one or more network computing stations and one or more power autarkic network computing stations supplied by one or more associated local power generators. The power autarkic network computing stations and the local power generators are connected with a local power network. A control signal is sent to a resource managing unit of the network computing cluster via a communication network. The control signal indicates the ability of the power autarkic network computing stations to process IT-services. The resource managing unit receives the control signal via the communication network. Triggered by the control signal, the resource managing unit sends a signal for transferring an IT-service processed by a network computing station of the network computing stations to the network computing station via the communication network.

Patent number: 7860524Abstract: The invention concerns a method of providing a Push-to-Talk (=PTT) service within one or more telecommunication networks (1, 2, 3, 4) by means of a gateway-server (5) which sets up a virtual connection per PTT connection. The virtual connection provides information about the participating terminals (10, 20, 30, 40) of the PTT connection, the service type to reach each terminal (10, 20, 30, 40), and the connection status of each terminal (10, 20, 30, 40). Thus, the gateway-server (5) is capable of providing the PTT service within and/or across different telecommunication networks comprising radio access telecommunication networks (1), fixed wire-line telecommunication networks (2), circuit-switched telecommunication networks (3), and packet-switched telecommunication networks (4).Type: GrantFiled: February 22, 2006Date of Patent: December 28, 2010Assignee: Alcatel LucentInventors: Volker Laible, Stefan Wahl, Dieter Kopp

Patent number: 7756260Abstract: The invention concerns a method for providing features to the user of a telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) that is connected to a central unit (CU) whereby, if said telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) is currently not interconnected via the central unit (CU), said telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) notifies the central unit (CU) at least about certain kinds of user activities, in case of such notification the central unit (CU) checks whether it is currently interconnected to another telephone assigned to the same subscriber as said notifying telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) and in case of the existence of such interconnection, the notifying telephone (HSA1, . . . HSAn, HSS1, . . . HSSm) is interconnected in parallel to this interconnection, and if said notifying telephone (HSA1, . . . HSAn, HSS1, . . .
