Abstract: A peer-to-peer email system and methods are provided for distributed email distribution, prevention of SPAM, and efficient email storage. Each email client also serves as a node in the peer-to-peer system, relaying email messages and/or attachments. Large attachments may be transmitted directly from sender to receiver, and if the receiver is not online at the time the sender sends the attachment, the receiver can request the attachment from the sender at a later time.

Abstract: Described is a seal segment (310) for a gas turbine engine, comprising: a gas facing wall (312) having a gas facing surface (314) and a first internal surface (316); an outboard wall (318) having an outboard facing surface (320) and a second internal surface (322) which is radially separated from the first internal surface with a gap therebetween; a first conduit (324) located between the first and second internal surfaces; and, a second conduit (326) located between the first and second internal surfaces, wherein the first and second conduits are radially separated by a party wall (328).

Abstract: A Peer-to-Peer (“P2P”) email and social networking system for use by plural users to exchange emails and attachments includes a mesh network that includes plural node computers, each running a P2P email client, and each constructed to transmit and receive emails. The emails are stored in mailboxes residing on each node computer, and may be encrypted during transmission, and may remain encrypted while stored at each node computer.

Abstract: Methods of paying debt over a network and debtor computer systems are provided for forming a secure email link between the debtor computer system and a creditor computer system; transmitting a notice of debt from the creditor computer system to the debtor computer system using the secure email link; and paying at least a portion of the debt at the debtor computer system based upon the notice of debt. The secure email link may be formed over a peer-to-peer email system.

Abstract: A wall cooling arrangement comprising on one side of a wall a multiplicity of cooling fluid inlet apertures and on the opposite of the wall a multiplicity of cooling fluid exit apertures, and in the body of the wall linking said inlet and exit apertures a network of multiply branched cooling passages. Flow of cooling fluid through a network is controlled by a throat positioned either at or close to the inlet to the passage network or at a location part way through the network, in which case there may be a plurality of inlet apertures feeding through a single throat to a plurality of outlet apertures.

Abstract: A component such as a turbine blade of a gas turbine engine has a cooling arrangement comprising a cascade impingement array in which cooling air flows from a supply chamber through impingement passages in webs to an internal passageway comprising first and second limbs. The cooling air flow through the limbs, provides improved heat transfer compared with continued impingement cooling in the chordwise direction of the blade.

Abstract: A downhole oil well fluted safety joint for use with a production string in cased hole provides an elongated tubular body having an internal open-ended flow bore and a plurality of radially spaced apart flutes extending from the bottom of the tool bore outer surface. The flutes provide spaces therebetween that allow fluid to circulate in the casing externally of the tool body above and below the fluted portions so that gravel can be pumped past the flutes, for example, to pack a screen and liner which is run below the tool body in typical installations. The tool is used, for example, to guide wire line or wash pipe inside a screen liner in order to check for fill and to prevent the wire line or wash pipe from inadvertently traveling on the outside of the tool body and thus, beside instead of inside the screen liner.

Abstract: A simple and sturdy stand for motorcycles known as dirt bikes that may be positioned between the wheels of the dirt bike and operable by the foot of the user for engaging its frame to raise and lower the front wheel of the dirt bike off of its supporting surface.
