Abstract: A process of producing a ceramic matrix composite turbine bucket, an insert for a ceramic matrix composite turbine bucket, and a ceramic matrix composite turbine bucket are disclosed. The process includes providing a bucket preform having a dovetail cavity, the dovetail cavity being enclosed within a dovetail shank of the bucket preform, positioning an insert within the dovetail cavity, then forming the ceramic matrix composite turbine bucket in a furnace. The insert includes a geometry configured to be fit within a dovetail cavity of the ceramic matrix composite turbine bucket, a bucket preform, or both. The insert is foam material or a plurality of ceramic matrix composite plies. The ceramic matrix composite turbine bucket includes a dovetail shank and a dovetail cavity enclosed within the dovetail shank. The dovetail cavity is arranged and disposed for receiving an insert.

Abstract: In one aspect, a system for operating a power generation system within a battery storage/discharge mode or a dynamic brake mode may generally include a power convertor having a DC link, a switching module coupled to the DC link and a selector switch configured to selectively couple the switching module to one of a storage device or a resistive element of the power generation system. The selector switch may be movable between a first position, wherein the switching module is coupled to the storage device such that power is capable of being directed between the DC link and the storage device via control of the switching module, and a second position, wherein the switching module is coupled to the resistive element such that power is capable of being directed between the DC link and the resistive element via control of the switching module.

Abstract: Certain examples provide systems and methods for medical diagnostic collaboration. An example system includes a conversation manager to facilitate a first conversation between a first device and a second device. The conversation manager manages a plurality of conversations based on respective conversation identifiers assigned to each of the plurality of conversations. The example system also includes a collaboration session manager to facilitate, via the first conversation, a collaboration session between the first and second devices, which allows a user of the first device and a user of the second device to view, share, and comment on a medical study. In addition, the example system includes a context manager to manage context information to describe a state of the medical study as it is displayed on the first device to synchronize a state of the medical study displayed on each of the first and second devices.

Application number: 20150147209
Abstract: A diaphragm pump and pump system including a pump housing defined along a longitudinal axis and having defined therein one or more pumping chambers and one or more driving chambers. At least two check valves communicating with each of the one or more pumping chambers for conducting a production fluid into and out of the pumping chamber. One or more flexible axially elongated diaphragms are mounted in the pump housing and sealingly separate the one or more pumping and driving chambers. At least one cam mechanism is disposed in the pump housing and coaxially therewith the pump housing longitudinal axis. The at least one cam mechanism is configured for rotational movement to provide for radial deflection of the one or more flexible axially elongated diaphragms into the one or more pumping chambers to effect pumping of a production fluid therethrough the diaphragm pump.

Application number: 20150147479
Abstract: A method for the formation of channels on a metallic substrate is described. The method includes the steps of applying at least one layer of a metallic coating material onto a surface of the substrate by a cold spray technique, so as to define boundary walls for the channels, and to build the boundary walls to a desired height. Additional coating material is then applied on one or more surfaces of the boundary walls by the cold spray technique, so as to modify the shape of the channels. The substrate can be any type of high-temperature component or hot gas path component. In some instances, the substrate is a gas turbine engine wall.

Abstract: A method for preparing an electrolyte separator for an electrochemical device is described. The method includes the step of applying a beta?-alumina coating composition, or a precursor thereof, to a porous substrate, by an atmospheric, thermal spray technique. An electrochemical device is also described. Some of these devices include an anode, a cathode, and an electrolyte separator disposed between the anode and the cathode. The separator includes a thermally-sprayed layer of beta?-alumina, disposed on a porous substrate. The electrochemical device can be used as an energy storage system, or for other types of end uses.
