Abstract: The present invention relates to a system for contactless induction of high-frequency vibrations in a volume of molten metal (1) during the manufacturing of a metal component or a metal matrix composite component. The system comprises a moveably arranged electromagnetic primary coil (2), adjustment means (3) for adjusting the position of the primary coil (2), and a control unit (5) for controlling the position of the primary coil (2) to a predefined distance above and not in physical contact with an upper free surface (4) of the molten metal (1) during use of the system. In some embodiments of the invention the molten metal (1) is contained in a foundry crucible (7) during manufacturing. In other embodiments, the system is used for an additive manufacturing system, so that the primary coil (2) is arranged above the melt pool (16). In both embodiments, a secondary low-frequency electromagnetic coil (9) may be arranged around and at a distance from the molten metal (1).

Abstract: The present invention relates to a method of manufacturing a metal matrix composite component (9). It comprises the use of a container (1) having a first compartment (2) and a second compartment (3) interconnected by a passage (4). A porous reinforcement preform (6) is placed in the first compartment (2), and matrix metal (7) is placed in the second compartment (3). The container (1) is then evacuated and sealed. The container (1) and its content is heated to above a melting temperature of the matrix metal (7) at least until the matrix metal (7) has melted. Then a high pressure P is applied to the outside of the container (1) so that at least the second compartment (3) is deformed to such an extent that melted matrix metal (7) is forced to flow via the passage (4) into the first compartment (2) and to infiltrate the porous reinforcement preform (6). The method may preferably be carried out in a hot isostatic pressure vessel (8).

Abstract: The present invention relates to a method of manufacturing a metallic component (1) wherein a plurality of layers of metallic wire (7) is wound around a mandrel or inner layer (2). An outer layer of a metallic material is provided around the wound layers of wire (7) so that a canister (8) is obtained. The canister (8) is then evacuated and sealed before it placed in a hot isostatic pressing device (9) at high pressure and high temperature for a predetermined period of time. Hereby at least a majority of the windings of wire (7) consolidate and diffusion-bond to form the metallic component (1). In some embodiments of the invention, the canister (8) and/or the mandrel/inner layer (2) is/are not removed after the consolidation and thus forms an integral part of the component (1).

Abstract: The present invention relates to a method of manufacturing a component 1 by additive manufacturing. The method comprises providing a work surface 2 on which the component 1 is to be manufactured, and providing at least one deposition material 3 from which the component 1 is to be composed. The deposition material, typically in the form of wire, is advanced to a localized deposition area 4 where it is added to the component 1 being manufactured. The method further comprises focusing at least one light beam 5 of incoherent light emitted from at least one heating source 6 in the deposition area 4 so that the deposition material 3 is deposited for building up the component 1. At least one light focusing mirror 7 and/or lens 11 is used to focus the incoherent light in the deposition area 4. The invention further relates to the use of such a method in space, such as on a space station, on a space craft or on parabolic flights for testing.

Abstract: Systems and methods, comprising a directed heat source coupled to a multi-wire feed-head configured to feed one or more wires having diverse compositions into a heat affected region, are provided for the synthesis of alloy samples having defined compositions, combinatorial alloy sample series and libraries, and shaped alloy components.

Abstract: A method includes receiving an initial electronic file where the initial electronic file is associated with a work product. The method further includes resolving, automatically, an electronic file content type associated with the initial electronic file and executing, automatically, at least one subscription program associated with the electronic file content type of the initial electronic file. The method further includes retrieving an enhanced electronic file based on a matter security level. The enhanced electronic file is associated with an indication of completion of the at least one subscription program. Another embodiment includes extracting a set of metadata from the initial electronic file and storing the set of metadata from the initial electronic file in a memory. Yet another embodiment includes populating, automatically, at least one field within a field-oriented electronic file from the set of metadata.

Abstract: Systems and techniques are disclosed that allow a user to enter a query in a query input region of a graphical user interface and respond to the query by automatically directing it to an appropriate database, saving a user from having to choose among the myriad databases within the system. The system provides shareable folders for not only selected documents or excerpts from documents, but also for annotations and markups associated with documents. The system also enables a user to set permissions as to whether to allow documents, as well annotations and markups, private or publicly available to other users. Further, the system allows a user to specify an action that is to occur once a particular event occurs affecting a document, annotation or markup.

Abstract: Apparatus, positioned at an inlet port to a pump, for shielding the pump from a process chamber of a semiconductor wafer processing system, where the apparatus has a controllably variable effective throughput area, and method for electrically controlling the size of the effective throughput area. Specifically, the apparatus is a controllable restrictor shield supported by an actuator, having a first effective throughput area and a second effective throughput area, where the first effective throughput area is typically less than the second effective throughput area. The size of the effective throughput area is directly responsive to an electric signal that controls the actuator.

Abstract: Apparatus for retaining the data held in a directional counter in the event of the voltage level supplied to the counter falling below a predetermined level comprises a directional counter means for comparing the level of voltage supplied to the directional counter with a predetermined voltage level, data storing means responsive to the comparator means for storing the output signal of the directional counter when the voltage falls below the predetermined voltage and for loading the stored output signal into the directional counter when the voltage level subsequently rises above the predetermined level.
