In one embodiment, the present invention is a method and apparatus for DNS pre-fetching for multiple clients. In one embodiment, all packets coming into or going out of a local network are scanned for application protocol, domain names, and / or other information. If pre-defined criteria indicate that the network is interested in a particular domain name, a DNS lookup is performed and the corresponding IP address is cached by the local DNS server. The local DNS server is thereby able to quickly respond to future requests for the cached domain name. Moreover, because the IP address is cached at the local DNS server, any client connected to the local DNS server on the local network can request the cached domain name from the local DNS server and be quickly connected to the indicated domain name.

In an automated leads-and-bids matching system, bid profiles are defined to describe desires of lead buyers. Received leads are matched to active ones of the bid profiles whose specifications the leads substantially match. Lead segmentation data is captured on-the-fly for example by inducing potential consumers to navigate their way through tree-organized web sites that categorize the consumers according to their geographic location, income / revenue range, class of products desired and / or other attributes. Live voice or other telecommunication connections to the pre-classified consumers are coupled to corresponding, pre-classified telecommunication nodes of a call processing system. The call processing system deduces the segmentation data of the consumers from the identities of the pre-classified nodes through which their connections pass. The deduced segmentation data is passed to an automated matching system or auctioning subsystem that finds the highest bids for each given lead. A quality rating database rates the quality of leads provided by different sellers. A price discounting engine discounts the amount paid to sellers who are hot-rated as sources of inferior leads.

Existing floating handguards have the problem of adding size and weight to M16 style gas operated rifles because these tubular handguards attach to a relatively large diametral surface which lies outward of a firearm operating member or gas tube. Existing handguards are mounted thus so that the handguard inside surface will mechanically clear the gas tube. The present invention solves this problem by providing a handguard system integrated to a firearm, the system having a one-piece extended barrel nut with a smaller diameter outer surface configured to lie inward of the gas tube, between the gas tube and the barrel. A one-piece generally tubular handguard has an outer surface with a longitudinal rib and an inner surface with an inner diameter and a groove which is aligned with the rib. The handguard inner diameter engages the barrel nut outer surface and the groove provides clearance for the gas tube. The rib is configured to maintain the rigidity of the handguard adjacent the groove.

A system for capturing displaced fluid or pumping fluid through tubulars being run into or out of the wellbore is described. Embodiments are supported by a traveling block and top drive unit with telescoping features to rapidly seal over a tubular to connect the tubular to a mud system. Alternative sealing arrangements for sealing inside the tubular connection are also disclosed. These alternate sealing arrangements also provide flow areas larger than the tubular body since no portion of these arrangements enter the tubular body. All of the sealing arrangements provide a biased area whereby any internal pressure in the invention forces the seals into more intimate contact with their mating seal surfaces. A mudsaver valve having a large flow capacity is described to keep fluid from spilling when the apparatus is removed from the tubular. This mudsaver valve also provides for pumping of fluid into the tubular or flow of fluid from the tubular to the mud system prior to removing the apparatus from the tubular. In these embodiments, the apparatus can be placed in threaded sealing contact with the tubular and can incorporate a safety valve that can be manually closed in the event of a well kick. In another embodiment, a singular control input accomplishes operation of the apparatus to extend or retract the telescoping feature. Also illustrated is a drain valve that provides a method of completely removing all fluid pressure from within the apparatus prior to removing the apparatus from the tubular. The drain system also provides a means of disposing of the excess fluid away from the rig floor where spillage is a danger to the personnel or environment. The drain system can also be connected to a scavenger system that is intended as a vacuum system for removal of spillage. Connection to this system eliminates all possible spillage and completely removes fluids from the tubular handling area.
