Abstract: A system includes a name server, an edge cache server, and a local cache server. The name server is configured to provide an anycast IP address in response to a request for an IP address of an origin hostname from a client system. The edge cache server is configured to respond to the anycast IP address and a unicast IP address and to retrieve content from an origin. The local cache server includes a storage and is configured to respond to the anycast IP address, to retrieve content from the edge cache server, and provide the content to a client system.

Abstract: A method of delivering content to a client includes receiving a request for the content from the client at a first server, determining the size of the content, and determining an optimal server to provide the content. The method further includes redirecting the client to the optimal server when the size of the content is above a threshold.

Abstract: A system for accessing documents from a main storage utilizing proxies and caches. Each of the documents is also assigned to one and only one of the caches. Users access the system through proxies, which are able to determine which cache stores the document. Proxies retrieve the documents through the caches. If the cache does not contain the document, only then is the document retrieved through the main server.

Abstract: Chaff for protecting a ballistic missile from detection by radar during re-entry into the atmosphere is shown to be made up of a plurality of dart like elements, each fabricated from pyrolytically formed graphite and shaped so as to follow a ballistic path through the atmosphere upon release from said missile and to appear as a resonant dipole to interrogating signals from a radar.

Abstract: Organic materials are separated and retrieved by mixing them with a liquid medium which is solid at room temperature and which is at atmosphere pressure. The material and medium are pumped by an electromagnetic pump while creating turbulence and then the velocity of the medium is decreased while heat is applied. Gases generated during the application of heat are collected. The medium is then cooled and returned to the pool at atmospheric pressure.

Abstract: Heat exchange apparatus for improving the efficiency of a fireplace is disclosed in the form of a plurality of heat transfer conduits connected at one end to a manifold and containing a plurality of heat exchange elements. A fan means directs air through the manifold and then through the conduits for contact with the heat exchange elements to thereby heat the air which is then discharged into a room.

Abstract: A kinetic energy penetrator assembly includes a motor casing having an aft pening. A nozzle with a nozzle opening is seated in the aft opening of the casing and confines expanding gases produced by burning propellant in the casing to a configuration for applying a thrust to the casing. An aft pusher plate is connected to a plug which plugs the nozzle opening and which has an aft space for receiving expanding gases. A penetrator rod is connected to the forward end of the motor casing and includes a bore riding sabot having substantially the same diameter as the diameter of the pusher plate and an aft portion of the motor casing. The penetrator assembly is meant to be launched from a gun with expanding gases in the gun barrel pushing against the pusher plate and ejecting the penetrator at some velocity from the barrel bore.
