  • Publication number: 20240323190
    Abstract: A system enables a publisher to specify access to people-based identifiers in a cookieless authentication environment. By giving the publisher the ability to grant access to these identifiers only to trusted parties, data leakage is greatly reduced. Permission is controlled by encrypting the same identifiers using one of a plurality of keys, so that only those parties to whom the publisher desires to give access associated with a particular key may access the information. An application programming interface operated by a resolution vendor accepts publisher identifiers and, after resolution of those identifiers into persons, returns envelope data structures that contain encrypted identifiers for persons. A sidecar process handles decryption and re-encryption of the envelopes as needed to support the identification environment.

  • Publication number: 20240261917
    Abstract: Tool rack for an automatic machine comprising a control unit and a positioning platform connectable to a plurality of tools, the tool rack having a linear guide, one tool station or more than one tool stations connected to the linear guide for receiving and/or providing at least one of said plurality of tools in an operating volume of the positioning platform, a position transducer for detecting a position of the tool station or at least one of the tool stations relative to the linear guide and transmitting the position to the control unit.

  • Patent number: 11223059
    Abstract: Method and power plant comprising a Solid Oxide Fuel Cell (SOFC) for production of electrical energy and H2 gas. The power plant is charged with a feed gas selected from the group consisting of natural gas, bio-gas and syngas. The feed gas, prior to being fed to the SOFC, is reformed in a reformer with a CaO containing CO2 absorber, thereby producing a carbon free H2 gas as feed for the SOFC while converting CaO to CaCO3. The latter is regenerated to CaO in an endothermic reaction in a CaO regenerator at a temperature of at least 850° C. utilizing heat from the SOFC to heat the regenerator. A heat exchange medium collects heat in the SOFC and is subjected to further temperature increase in a heating device before being subjected to heat exchange in the CaO regenerator.

  • Patent number: 10927008
    Abstract: Method and device for biogas upgrading and hydrogen production from anaerobic fermentation of biological material under production of energy rich gases selected among methane and hydrogen or a combination thereof. The method comprises addition of hydrogen gas to a fermentation step to enhance the methane: CO2 ratio in the raw biogas produced. At least part of the raw biogas is subjected to a step of sorption enhanced reforming without prior separation of CO2, using CaO as an absorbent to capture CO2 from the raw biogas as well as CO2 released in the reforming reaction. CaO is regenerated in an endothermic reaction using heat at least partially provided, directly or indirectly, by the bio-gas to be upgraded, thereby producing substantially pure hydrogen and substantially pure CO2.

  • Patent number: 9574600
    Abstract: The invention relates to an assembly for a turbine engine, the assembly comprising a tubular shaft (60), a nut (64) screwed onto an end portion of said tubular shaft (60), and a locking member (86) for locking the nut (64) on the shaft (60), said member (86) including means (90, 78) for coupling in rotation with the nut (64) and means (92, 68) for coupling in rotation with the shaft (60), said member (86) being movable between a position for coupling the nut (64) in rotation relative to the shaft (60), and a position for releasing the nut (64) relative to the shaft (60). The nut (64) includes a housing (72) in which said member (86) is suitable for being held when in its release position.

  • Patent number: 9550147
    Abstract: A particulate, heterogeneous solid CO2 absorbent composition, comprising decomposition products of Ca3Al2O6 after having been heated to a temperature between 500° C. and 925° C. in the presence of H2O and CO2 for a period of time sufficient to allow the Ca3Al2O6 to react and form the particulate, heterogeneous absorbent composition which exhibits a higher concentration of aluminum than calcium in the particle core but a higher concentration of calcium than aluminum at the particle surface. The invention also comprises a method for preparing the particulate, heterogeneous product as well as a method for utilizing the composition for separating CO2 from a process gas.
