  • Publication number: 20230152938
    Abstract: In some implementations, a device may receive, via a data stream, log data associated with a set of register devices and may extract state information associated with the set of register devices from the log data. The device may transmit, to a client device, presentation information to cause the state information associated with the set of register devices and one or more user selection options for initiating actions to be performed by the set of register devices to be displayed by the client device via a graphical user interface (GUI). The device may receive an indication of a user input provided via the GUI associated with a user selection option of the one or more user selection options, that indicates an action to be performed by a register device. The device may communicate, with the register device, to cause the register device to perform the action.

  • Publication number: 20210239651
    Abstract: The invention relates to an ion transport device which is designed to transport ions by means of an electric field. The ion transport device has an ion transport channel in which an ion transport chamber is formed. In order to generate the electric field, the ion transport device has a plurality of field generating electrodes which are arranged one behind the other along the length of the ion transport channel in order to move ions through the ion transport chamber in a transport direction. The invention additionally relates to an ion mobility spectrometer and to a mass spectrometer.

  • Patent number: 8491959
    Abstract: In various embodiments, a sputtering target initially formed by ingot metallurgy or powder metallurgy and comprising a sputtering-target material is provided, the sputtering-target material (i) comprising a refractory metal, (ii) defining a recessed furrow therein, and (iii) having a first grain size and a first crystalline microstructure. A powder is spray-deposited within the furrow to form a layer therein, the layer (i) comprising the metal, (ii) having a second grain size finer than the first grain size, and (iii) having a second crystalline microstructure more random than the first crystalline microstructure. Spray-depositing the powder within the furrow forms a distinct boundary line between the layer and the sputtering-target material.

  • Patent number: 8002169
    Abstract: In various embodiments, a method of joining clad structures includes providing first and second clad structures each comprising a protective layer disposed only partially over a steel layer such that an edge region of the steel layer is exposed, joining the first and second clad structures at their respective edge regions, thereby forming a joint, and cold spraying a metal powder over and in contact with (i) the joint, (ii) the edge regions, and (iii) the protective layers of the first and second clad structures, thereby directly connecting the protective layers of the first and second clad structures with a layer of unmelted metal powder.

  • Publication number: 20110132534
    Abstract: The present invention is directed to a process for joining tantalum clad steel structures. The process broadly comprises: a) providing a first tantalum clad section, said first tantalum clad section comprising a tantalum layer over a steel layer, with a bonding layer optionally therebetween, with a portion of said steel layer in an edge region not being covered by said tantalum layer or said bonding layer, b) providing a second tantalum clad section, said second tantalum clad section comprising a tantalum layer over a. steel layer, with a bonding layer optionally therebetween, with a portion of said steel layer in an edge region not being covered by said tantalum layer or said bonding layer, c) locating said steel edge regions adjacent each other, d) welding the steel edge regions together, e) cold spraying a tantalum powder onto the welded edge regions and over the tantalum layers adjacent said edge regions thereby joining the tantalum clad steel sections.
