Abstract: A closable tube assembly including a tube vessel, a first cap assembly, and a second cap assembly. The tube vessel has walls defining an opening to an interior of the tube vessel. The first cap is removably connected to the tube vessel over the opening and engages an edge of the opening and the tube vessel interior to close the opening at least in part. The second cap is removably connected to the tube vessel and the first cap so that opening closure is commonly effected by both the first cap and the second cap. Removal of the second cap opens the opening with the first cap engaged to the edge of the opening. Both the first cap and the second cap have an insert closure configuration relative to the opening, and the second cap has an insert configuration relative to the first cap.

Abstract: There is disclosed an electronic trading system and associated methods adapted to automatically match submitted orders on the basis of price, quantity limitations, and lines of credit defined by potential counterparties. Lines of credit are divided into time based tranches relating to the maturity of an instrument to be traded, and a number of schemes are used to manage the tranches in order to improve control and use of remaining credit, which can be replenished manually or automatically. Traders are grouped into desks, and orders submitted by a trader may be matched on behalf of any of several credit centers defined per trader desk. Lines of credit may be held in various ways such as at the level of counterparty trading organizations, and at the level of counterparty credit centers.
