Abstract: The present invention relates to a process for the manufacture of microporous carbon materials to perform selective separations of nitrogen in gas mixtures such as hydrogen sulfide, carbon dioxide, methane and C2, C3 and C4+ hydrocarbons, with high efficiency, shaped of microspheres or cylinders from copolymers of poly (vinylidene chloride-co-methyl acrylate) with density of 1.3 to 1.85 g/cm·sup·3 or poly (vinylidene chloride-co-vinyl chloride) with density of 1.3 to 1.85 g/cm.sup.3, using two stages. The first stage consists of a surface passivation of the material by chemical attack in a highly alkaline alcohol solution, with the aim of effecting a precarbonization on the surface of the copolymer that during the pyrolysis process is not deformed and gradually develops microporosity. The material of the first stage presents, in the layer, percentages between 55% to 85% carbon, between 5% to 20% oxygen, and between 10% to 40% chlorine.

Abstract: Automated choke control apparatus and methods are disclosed herein. An apparatus for automatically controlling a choke valve comprises a controller. The controller is to control a choke position of the choke valve via a first control loop in response to selection of a first one of a plurality of operation modes being detected. The controller is further to control a wellhead pressure of a wellhead via a second control loop in response to selection of a second one of the plurality of operation modes being detected, the wellhead being operatively coupled to the choke valve.

Abstract: Rate reduction for an application controller is provided. Computing resources used by an application controller receiving an amount of traffic from a network device can be determined. A determination whether the computing resources used by the application controller are approaching a computing capacity of the application controller can be made. A message can be sent to the network device to reduce the amount of traffic sent to the application controller in response to a determination that the application controller is approaching the computing capacity. A reduced amount of traffic can be received from the network device. Incrementally increasing amounts of traffic can be received from the network device after receiving the reduced amount of traffic from the network device.

Abstract: An example system includes a handler device and an edge device. The handler device is configured to receive a first packet, generate a second packet by encapsulating the first packet in a tunnel format, and forward the second packet, wherein the destination address of the second packet is a multicast address assigned to a home network associated with the handler device. The edge device configured to receive the second packet, decapsulate the second packet to obtain the first packet, and forward the first packet to one or more clients associated with the home network.

Abstract: A system includes a source including a memory storing: at least two encrypted files making up an installation image, each file encrypted with a key; a metadata file including an index to each key and a hash value for each encrypted file; a signature file providing a digital signature for the metadata file, the metadata file digitally signed with a private certificate; and a public certificate associated with the private certificate.
