Abstract: An apparatus includes a multi-tenant computer system including a processor and a memory operatively coupled to the processor. The apparatus receives a first service request from a first compute device and a second service request from a second compute device. Data values of the first service request are not accessible by the second compute device and data values of the second request are not accessible by the first compute device. The apparatus merges the data values of the first service request and the data values of the second service request and filters the results based on a set of rules not accessible to the second compute device to produce a first filtered result responsive to the second service request. The apparatus also filters the results based on a set of rules not accessible to the first compute device to produce a second filtered result responsive to the first service request.

Abstract: In a method for producing a brake disc, a friction surface layer is sprayed onto the base body or onto an intermediate layer applied on the base body by cold gas spraying a particle mixture which consists 25 to 75% by weight of a metal matrix material and 75 to 25% by weight of a carbide material. The metal matrix material consists of an iron-based alloy, nickel-based alloy, titanium or titanium alloy. The carbide material consists of tungsten carbide, titanium carbide, iron carbide, silicon carbide, chromium carbide or niobium carbide.

Abstract: In some embodiments, a non-transitory processor-readable medium receives, from a client compute device and at a multi-tenant computer system, a service request that includes an authentication token provided by a third-party compute device and that identifies a single-tenant account (1) of the multi-tenant computer system and (2) associated with the client compute device. The medium sends an information request for first information associated with the service request to the third-party compute device. The medium receives the first information from the third-party compute device in response to the information request. The medium processes the service request based on the first information to produce a service result responsive to the service request. The medium sends the service result to the client compute device.

Abstract: A reformer tube processing and filling system is provided for ensuring uniformity of reformer tube flow rates and reactivity. The disclosed invention provides a system for detecting and removing tube obstructions, as well as an automated process for verifying the flow rate for each tube and identifying tubes with abnormal flow rates to remove a source of human error and conserve labor costs. An automated tube filling system provides a calibrated fill mechanism coordinated with a calibrated loading rope withdrawal mechanism to ensure loading consistency. A lack of vibrating parts ensures a low dust count, and what little dust is present is removed via a built-in vacuum outlet in the loader.

Abstract: A method and corresponding apparatus for separation of carbon dioxide from an exhaust gas of a fossil-fired power are provided. In an absorption process, the exhaust gas containing carbon dioxide is brought into contact with an absorption medium so that the absorption medium is laden with carbon dioxide. In a desorption process, vapor from a water/steam circuit of the fossil-fired power plant is heated, wherein a laden absorption medium is regenerated. In a subsequent expansion process, the regenerated absorption medium is expanded so that a vapor and an expanded absorption medium are formed, wherein the vapor is recirculated into the desorption process. The laden absorption medium is divided into a first part stream and a second part stream. Only the second part stream is brought into heat-exchanging contact with the expanded absorption medium. The first and second part streams are supplied to the desorption process at different process stages.
