Abstract: This disclosure provides a devices and systems for securing a gas turbine nozzle segment and sealing one or more cooling cavities of the gas turbine nozzle segment during manufacturing. The device can have a support assembly for receiving a nozzle segment having at least one cooling cavity. The device can have at least one clamp assembly configured to secure a first portion of the nozzle segment to the support assembly. The at least one clamp assembly having a first clamp arm, and a first tightening assembly coupling the first clamp arm to the support assembly. The device can have a first port seal assembly having at least one sealing member coupled to the first seal body and configured to interact with and seal the corresponding one or more cooling cavities.

Abstract: A method and system are provided for computing an optimal restoration capacity and/or optimal restoration paths for a network to resolve a restoration scenario by solving a linear program (LP) model. The LP model includes decision variables corresponding to restoration capacity and restoration paths and constraints requiring restoration of traffic and conservation of capacity in the network. For example, the system determines a set of network paths that need to be restored in the network, preprocesses network data corresponding to the network to reduce LP processing workload and time; generates possible restoration paths and solves the LP model, preferably through column generation methods, to determine the optimal restoration capacity and/or the optimal restoration paths to resolve the restoration scenario; changes the LP solution into integer form, as necessary, and changes the LP solution in integer form to the original format of the network data or an equivalent thereof.

Abstract: The invention relates to a RTV silicone composition having increased hot oil resistance upon curing. The RTV silicone composition comprises a polydiorganosiloxane, an acyloxy-functional crosslinker, a metal salt of a carboxylic acid catalyst, a filler, and a metal acetate. In a preferred embodiment a metal acetylacetonate is also added.
