  • Publication number: 20250146713
    Abstract: Wellbore synthesis techniques are disclosed suitable for use in geothermal applications. Embodiments are provided where open hole drilled wellbores are sealed while drilling in sequenced operations with utilization of phase change materials to form an impervious layer at the wellbore/formation interface in high temperature applications. The techniques may be chemical, thermal, mechanical, biological and are fully intended to irreversibly damage the formation in terms of the permeability thereof. With the permeability negated, the wellbore may be used to create a closed loop surface to surface geothermal well operable in the absence of well casing for heat transfer surfaces for maximizing thermal transfer to a circulating working fluid. Formulations for the working and drilling fluids are disclosed.

  • Patent number: 12170696
    Abstract: Some embodiments provide a method gaining insight into applicability of policies that authorize access to at least one service through application programming interface (API) calls by a plurality of users. The method receives an authentication policy that defines multiple users of a system providing the service, and also receives an authorization policy that defines access to the service by the users. The method generates an authorization policy for defining access to the service by authenticated users by combining the first and second policies. The method receives a query regarding access to the service from a particular set of one or more users, and uses the third policy to provide a response to the query that describes access to the service for the particular user set.

  • Publication number: 20240328177
    Abstract: A system and a method include a cam locking assembly including a support rod having a rod body that extends along an axis, a first rail component having a rail body that extends along the axis and coupled with the support rod and a third rail component, a cam having an interior passage extending along the axis that receives a portion of the support rod and an exterior surface having plural recesses, and guide pins that extend into the plural recesses of the cam and control movement of the cam. Movement of the cam controls movement of the third rail component between a loaded position and an unloaded position.

  • Publication number: 20240328432
    Abstract: The casing treatment system includes a compressor having an injection port, an extraction portion, a recirculation channel. It is also contemplated for the casing treatment system to include a plurality of injection ports, a plurality of extraction ports, and/or a plurality of recirculation channels. The casing treatment system is based on using the differences in the flow field at peak efficiency and near stall to “turn on” the recirculation at near stall operation to extend the stall margin, and to “turn off” the recirculation at peak efficiency operation to minimize impact to efficiency.

  • Patent number: 12097666
    Abstract: In various embodiments, a hot melt device comprising a heating device that is automatically or manually triggered is configured so as to have its melt surface applied bringing a thermoplastic material in its solid form into contact with a surface via mechanical extrusion; using a heater to heat the thermoplastic material to a temperature above a melting temperature of the thermoplastic material while maintaining the contact of the thermoplastic material with the surface; allowing the heated thermoplastic material to cool to a temperature that is below the thermoplastic material's melting temperature; and allowing the heated thermoplastic material to bond the hot melt apparatus to the contacted surface without a solvent or use of a curing chemical reaction when the heated thermoplastic material is cooled to below the thermoplastic material's melting temperature while remaining connected to the structural body.

  • Patent number: 12020086
    Abstract: Some embodiments of the invention provide a system for defining, distributing and enforcing policies for authorizing API (Application Programming Interface) calls to applications executing on one or more sets of associated machines (e.g., virtual machines, containers, computers, etc.) in one or more datacenters. This system has a set of one or more servers that acts as a logically centralized resource for defining and storing policies and parameters for evaluating these policies. The server set in some embodiments also enforces these API-authorizing policies. Conjunctively, or alternatively, the server set in some embodiments distributes the defined policies and parameters to policy-enforcing local agents that execute near the applications that process the API calls.

  • Patent number: 12003543
    Abstract: Some embodiments of the invention provide a method of modifying and validating API requests received at an API server. At a mutating admission controller of the API server, the method intercepts an API request received at the API server. The method invokes a mutating webhook to query a policy agent that includes a set of policies for modifying API requests to determine whether the API request requires modifications. When the policy agent determines that the API request requires modifications based on an identified policy from the set of policies, the method performs the modifications and forwards the modified API request for validation by the API server. After the API server has validated the API request, the method intercepts the API request at a validating admission controller and invokes a validating webhook to query the policy agent to determine whether the API request is valid.

  • Publication number: 20240110731
    Abstract: Closed loop wellbore configurations with unrestricted geometry for accommodating irregular or challenging thermal gradients within a thermally productive formation are disclosed. A working fluid is utilized in the loop for extraction of thermal energy there from. The loop and the unrestricted geometry are achieved using magnetic ranging of independent drilling operations which intersect from an inlet well and outlet well to form an interconnecting segment. In conjunction with the directional drilling, conditioning operations are incorporated to condition the rock face, cool the entire system, activate the wellbore for treatment to optimize thermal transfer inter alia. The significant degree of freedom in wellbore configuration is further optimized by the absence of mechanical impediments such as casing or liners in the heat transfer areas.

  • Patent number: 11938536
    Abstract: Metal powder particles for use in additive manufacturing are made by removing material from the surface of the particles using wet chemical etching to create a nanoscale texturing of the surface, increasing absorptivity by the metal powder particles of incident laser light and maintaining flowability. The nanoscale texturing has sub-wavelength features at laser wavelengths in the range 800-1100 nm. The particles are substantially spherical and have mean diameters in the range 10-70 ?m.

  • Patent number: 11645423
    Abstract: Some embodiments provide API (Application Programming Interface) authorization platform that allows API-authorization policy stacks to be created and enforced. Policy stacks (called “stacks”) define API-authorization policies across different sets of managed resources in a workspace. A stack in some embodiments defines a uniform set of one or more API-authorization policies for multiple different sets of resources so that the set of policies do not have to be specified independently for each set of resources. By instituting common policies across multiple managed resource sets (also called managed systems), stacks can be used to guarantee uniform baseline policies for the workspace.
