摘要： A top entry trunnion mounted rotary ball valve suitable for safe in-line maintenance, comprising a main valve body having an upstream and a downstream ball seat assembly, the ball seat assemblies further comprising a soft insert seal, a ball seat, a seat retainer and a plurality of compression springs in between the ball seat and the seat retainer. A guiding groove on the cylindrical surface of each of the ball seats, having a first end and a second end at an axial distance equal to or more than the measure of retraction required so as to get the mechanical clearance adequate to remove or assemble the ball member, the angular span between the first end and the second end of the guiding groove can be less than 180 degrees or more than 360 degrees, depending on the overall size of rotary ball valve, in order to be able to manually retract in the ball seats. Each ball seat is retracted in the recess, with the aid of a guide assembly, by using a straight rod, against a force Fc of the compression springs and the mechanical clearance is created between the ball member and the soft insert seal, to remove or assemble the ball member and or any or all components from or inside the valve body. An angle of grove a, which is an angle between the flange and the guide groove, is kept of relatively of low value for big sized valves whence an angular span of guiding groove becomes relatively higher so that the required axial distance, which is equal to or more than the measure of retraction required so as to get the mechanical clearance adequate to remove the ball member, is attainable between the first end of the groove and the second end of the groove, by a Force Ft apply-able by a person of normal physique, and vice versa for a small sized valve. The rotary ball valve cannot be put in operation inadvertently if the ball seats are in retractable or retracted position.

摘要： A mechanism for peer-to-peer file sharing by individual client networking applications is disclosed. A method of the invention includes sending to a server computing machine a request to access data by a networking application of a client computing machine; identifying to the server computing machine an ability of the client computing machine to seed data to peers of the client computing machine, receiving at the networking application a list of contact information of one or more peers of the client computing machine that have at least a portion of the requested data, selecting by the networking application one or more peers from the received list to download the data from, wherein the selection is prioritized based on a geographic proximity of the one or more peers to the client computing machine, and requesting by the networking application the content from the selected one or more peers.
