Abstract: This disclosure describes systems, methods, and apparatus to protect users of the Internet from DNS outages. In particular, an outage avoidance system is provided that includes query processing, outage avoidance processing, and a local cache, all configured to extend the TTL of expired answers to DNS queries or to ignore the expiration of an answer's TTL value, and thereby provide the expired answer in response to a client request when a DNS server is unable to obtain an answer from a remote DNS server.

Abstract: A process for producing an IPA/PET copolymer fiber that is homogenous having a substantially level, single IPA copolymer content, said fiber having improved pilling resistance and dye uptake.

Abstract: This disclosure describes systems, methods, and apparatus for sharing DNS answers between DNS server systems within a DNS cluster, between proxy servers, and/or between DNS server systems of different DNS clusters. When a DNS answer is obtained by a DNS server system, the answer can be shared with peer DNS server systems within a same DNS cluster or with DNS server systems having a logical relation to the first DNS server system (e.g., geographic relationship), but being in different DNS clusters. Proxy servers may also mediate communication between a client and the DNS clusters. These proxies can also include the ability to share DNS answers between each other.

Abstract: This disclosure describes systems, methods, and apparatus for forward and reverse DNS translation of IPv6 IP addresses. For a PTR request where the authoritative DNS server does not have a domain name associated with the IP address in the request, a DNS answer augmentation system can generate an IP address on the fly using one or more algorithms that take information about the request as an input. Similarly, for an AAAA request where the authoritative DNS server does not have an IP address associated with the domain name in the request, the DNS answer augmentation system can generate a domain name on-the-fly using one or more algorithms that take information about the request as an input. The DNS answer augmentation system can reside between a client or a DNS server and an authoritative DNS server or be a part of the authoritative DNS server.

Abstract: A textile cushioning batting for use in furniture and the like having a high degree of loft and rebound is disclosed comprising: a non-woven blended batting comprising a major portion of a fine denier fiber and a minor portion of a coarse denier fiber. The fibers have increased crimping amplitudes, secondary crimping, sharper crimp and optimized crimps per inch. A low melt binds fiber binding the fine and coarse denier fibers together in the batting; and a sufficient number of the fibers being heat are bonded together at their intersections to provide a high loft resilient batting for cushioning.

Abstract: A system is provided for connecting a battery to a mounting system. The battery is coupled to a battery connector, and the mounting system is coupled to a mounting system connector. The system includes an inner housing of the battery connector configured to receive a plurality of cables from the battery. The system further includes a respective plurality of male connectors or female receptacles positioned within the inner housing of the battery connector and coupled to the plurality of cables. The plurality of male connectors or female receptacles is configured to remain unexposed upon disconnecting the battery connector from the mounting connector during an unsafe event. The system further includes an outer housing of the battery connector surrounding the inner housing, where the outer housing includes a tapered wall.

Abstract: A method and system for determining a ground speed for locomotives (e.g., 12, 14) of a train (16) comprising at least two locomotives for use in controlling an operation of the train. The method includes selecting an axle of any one locomotive of the train for measuring a speed corresponding to the selected axle. The method also includes determining a ground speed for at least another locomotive of the train based on a measured speed corresponding to the selected axle of the one locomotive.

Abstract: A method is disclosed for spinning polyester staple to produce dark dyeing yarns as compared to yarns having an otherwise similar composition. The method includes spinning polyester staple into yarn, in which the polyester includes between about 0.5 and 4 percent by weight of polyethylene glycol, into yarn in a rotor spinning machine at a rotor speed of between about 110,000 and 120,000 rpm and at a tension of between about 2.5 and 3.2 grams/tex. A resulting polyester fiber is also disclosed of between about 1.2 and 2.25 denier per filament, and that contains between about 0.5 and 4 percent by weight of polyethylene glycol, and with a fiber tenacity of 4.7 grams per denier or less.

Abstract: Silicone-hydrocarbon compositions of matter having utility as lubricants and hydraulic fluids, especially brake fluids.

Abstract: Arene polymers can be made by oxidative coupling of arenes of at least 10 carbons, optionally with benzene, using liquid hydrogen fluoride, a catalytic amount of a molybdenum compound and oxygen as the oxidant.

Abstract: There are disclosed olefin polymerization catalysts based on tetra(neophyl) zirconium and its reaction products with surface-hydroxylated oxides of metals of Groups II(a), III(a), IV(a) and IV(b) of the Periodic Table of the Elements, processes for their preparation, and processes for the polymerization of olefinic monomers employing such catalysts. Neophyl zirconium aluminate supported on alumina is disclosed as the preferred, most active catalyst. The polyolefins produced are linear high polymers of high crystallinity such as polyethylene and isotactic polypropylene. Diolefins are converted into rubber by use of the process employing the catalyst. Ethylene-propylene copolymer rubbers can also be produced by use of the catalysts.

Abstract: There are disclosed a novel class of catalysts for olefin polymerization, processes for the production of this class of catalysts and processes for the production of linear polyolefins, including linear polyethylene, linear polypropylene and linear copolymers of ethylene with higher olefins, using this class of catalysts. The new class of catalysts comprises Group IV(a) transition metal hydrocarbyl hydride aluminates supported on alumina. The catalysts are produced by reacting a tetra(hydrocarbyl) transition metal compound [(R--CH.sub.2).sub.4 --M in which R is aryl, aralkyl or tertiary alkyl, and M is Ti, Zr or Hf] with partially hydrated (0.5 to 1.5% water of hydration) alumina to produce hydrocarbyl-transition metal aluminates on alumina followed by hydrogenation until from about 60% to 100%, preferably 90% to 100%, of the hydrocarbyl groups have been displaced and partially replaced by hydride, and the valence state of the transition metal has been reduced.
