Abstract: A thermal expansion system for actuating a remote operated sleeve assembly to open and close ports in a housing for fluidly communicating between a bore of a tubular string in a wellbore to the formation utilizes actuation of a propellant charge to create expanding gas and heat in a combustion chamber to directly act on one side of a piston connected to an axially moveable sleeve supported in the housing to shift the sleeve in one direction. Ignition of another propellant charge in a combustion chamber on an opposing side of the piston is used to directly shift the sleeve in an opposing direction.

Abstract: A three-position sleeve assembly having a housing with one or more housing ports and two sliding sleeves retained in a housing bore. The first sliding sleeve is movable between an open position to permit fluid flow through the housing ports, and a closed position to obstruct the housing ports with the first sleeve. The second sliding sleeve has one or more metering orifices and can be actuated to a metering position to align the metering orifices with the one or more housing ports to permit fluid flow through the housing ports at a metered flow rate, and an inactive position where the second sleeve is clear of the housing ports. The first and second sleeves can be actuated to set the sleeve assembly to an open mode, a closed mode, or a metering mode.

Abstract: A near end point of presence (PoP) of a cloud proxy service receives, from a client device, a request for a network resource. A far end PoP from a plurality of PoPs of the cloud proxy service is identified. Responsive to determining that a version of the network resource is stored in the near end PoP, a request for the network resource is transmitted to the far end PoP with a version identifier that identifies that version. The far end PoP receives, from the near end PoP, a response that includes difference(s) between the version of the network resource stored in the near end PoP with a most current version of the network resource. The response does not include the entire network resource. The near end PoP applies the specified difference(s) to the version that it has stored to generate an updated version of the network resource, and transmits it to the client device.

Abstract: A proxy server receives from a client device a request for a network resource that is hosted at an origin server for a domain. The proxy server transmits the request to the origin server. Responsive to determining that the origin server is offline, the proxy server determines whether the requested resource is available in cache. If it is in cache, the proxy server retrieves the requested resource from the cache and transmits the requested resource to the client device. The proxy server also transmits an offline browsing cookie to the client device for the domain such that when a subsequent request is received from the client device for a resource of the domain that includes the offline browsing cookie, a cached version of the requested resource will be served instead of querying the origin server.

Abstract: A proxy server receives from a client device a request to perform an action on an identified resource that is hosted at an origin server for a domain. The proxy server receives the request as a result of a DNS request for the domain resolving to the proxy server. The origin server is one of multiple origin servers that belong to different domains that resolve to the proxy server and are owned by different entities. The proxy server and the origin servers are owned by different entities. The proxy server analyzes the request to determine whether a visitor belonging to that request poses a threat. If the proxy server determines that the visitor poses a threat, the proxy server blocks the request and transmits a block page to the client device that indicates that the request has been blocked.
